Objective:To explore and analyze the effect of implementing a precise education model on the nursing care of perioperative patients in the interventional catheterization room.Methods:We selected 70 patients who were going to undergo surgical intervention in our hospital from August 2020 to December 2022 as the subjects for this study through random sampling.The patients were divided into a control group and an observation group,with 35 cases in each group.The control group underwent basic nursing intervention,and the observation group was given precise patient education.The nursing effects of both groups were observed.Results:After the intervention,all compliance indicators of the observation group were better than those of the control group(P<0.05).Besides,the incidence of complications in the observation group(2.86%)was lower than that of the control group(17.14%)with P<0.05.Furthermore,the patient satisfaction of the observation group(97.14%)was higher than that of the control group(82.86%),with P<0.05.Conclusion:A precise propaganda and education model facilitates the nursing of perioperative patients in the interventional catheterization room.Therefore,this practice should be popularized.

Anatomical variation in the internal jugular vein:potential risk factors for central venous catheterization-a case report

Central venous catheterization(CVC)is an invasive medical procedure used to measure central venous pressure and provides a stable route for continuous drug administration.CVC is widely used in the emergency department and intensive care units.It is typically performed by inserting a catheter through the internal jugular vein(IJV)into the superior vena cava near the right atrium.[1,2]While catheterization is a fundamental skill proficiently performed by healthcare professionals,lethal complications may occasionally occur because of undesirable positioning,depth and diameter.

How to manage the malposition of deep vein catheterization into the artery?

Central venous catheterization establishes temporary,efficient,and rapid use of deep venous access in patients,which provides high flow rate fluid perfusion,enables measurement of central venous pressure,and acts as an important reference for clinical decision-making.However,various complications such as pneumothorax,hemothorax,hematoma,and puncture failure can easily occur during the puncture and catheterization process.

Analysis of the Nursing Effect of Hierarchical Extended Nursing Based on The Guidance of Orem’s Theory in Patients with PICC Catheterization

Objective:To analyze the nursing effect of hierarchical extended nursing based on the guidance of Orem’s theory in patients with peripherally inserted central(PICC)catheterization.Methods:Ninety-one patients with PICC catheterization admitted to the hospital from May 2021 to May 2023 were selected and divided into a control group and an observation group,with 45 and 46 cases,respectively.The control group received routine nursing care,while the observation group received routine nursing care combined with hierarchical extended nursing based on the guidance of Orem’s theory for 3 months.Relevant indicators between the two groups were compared.Results:The improvement degree of various indicators in the observation group after nursing was better than that of the control group(P<0.05).Conclusion:Graded extended nursing based on the guidance of Orem’s theory improved the knowledge,belief,behavior,and self-efficacy of patients with PICC catheterization,and relieved their anxiety,depression,and other negative emotions.The nursing effect was deemed to be significant.

Pulmonary arterial hypertension confirmed by right heart catheterization following COVID-19 pneumonia: A case report and review of literature

BACKGROUND Pulmonary arterial hypertension(PAH)is a disease of the arterioles resulting in an increased resistance in pulmonary circulation with associated high pressures in the pulmonary arteries,causing irreversible remodeling of the pulmonary arterial walls.Coronavirus disease 2019(COVID-19)has been associated with development of new onset PAH in the literature leading to symptoms of dyspnea,cough and fatigue that persist in spite of resolution of acute COVID-19 infection.However,the majority of these cases of COVID related PAH were diagnosed using echocardiographic data or via right heart catheterization in mechanically ventilated patients.CASE SUMMARY Our case is the first reported case of COVID related PAH diagnosed by right heart catheterization in a non-mechanically ventilated patient.Right heart catheterization has been the gold standard for diagnosis of pulmonary hypertension.Our patient had right heart catheterization four months after her initial COVID-19 infection due to persistent dyspnea.CONCLUSION This revealed new onset PAH that developed following her infection with COVID-19,an emerging sequela of the infection.

A comparative study of TR Band and a new hemostatic compression device after transradial coronary catheterization

Objective: Transradial coronary catheterization has proved to be safe and effective in clinical practice. Various hemostatic compressive devices have been used in subsequent procedures. The objective of this study was to compare the efficacy and safety of a new hemostatic compression device and the widely used TR Band. Methods: A total of 118 patients were divided randomly into two groups: TR Band and the new hemostatic compression device. Efficacy of hemostasis, patient comfort, local vascular dysfunction, and radial artery occlusion(RAO) were evaluated and compared between groups. Results: Occurrence of errhysis or hematoma did not significantly differ between groups(13.6% vs. 11.9%, P = 0.782). Fewer patients had moderate to severe pain or moderate to severe numbness in the new hemostatic compression device group(1.7% vs. 22.0%; 1.7% vs. 18.6%, respectively). Pulse loss between distal artery and device was lower in the new hemostatic compression device group(5.1% vs. 22.0%, P = 0.007), and fewer patients experienced obstruction of venous reflux compared with the TR Band group(6.8% vs. 25.4%, P = 0.006). Combined incidence of RAO at discharge was 7.6%, and was lower in the new hemostatic compression device group(1.7% vs. 13.6%, P = 0.015). In contrast to the TR Band, application of the new hemostatic compression device was independently associated with lower incidence of RAO at discharge(odds ratio: 0.062, 95% confidence interval: 0.006–0.675, P = 0.022). Conclusions: Both the new hemostatic compression device and the TR Band can efficiently achieve hemostasis following transradial coronary catheterization. However, fewer patients felt discomfort with application of the new hemostatic compression device. Pulse loss in the artery distal to the compression device, obstruction of venous reflux, and RAO occurred significantly less often with application of the new device.

Catheterization of the gallbladder: A novel mouse model of severe acute cholangitis

AIM To establish a severe acute cholangitis(SAC) model in mice.METHODS Cholecystic catheterization was performed under the condition of bile duct ligation(BDL). Trans-cholecystic injection of lipopolysaccharide(LPS) was defined as the SAC animal model. Sham operation group, intraperitoneal injection of LPS without BDL group, intraperitoneal injection of LPS with BDL group and trans-cholecystic injection of normal saline with BDL group were defined as control groups. The survival rates and tissue injuries in liver, lungs and kidney were evaluated.RESULTS Mice in the SAC group showed a time-dependent mortality and much more severe tissue injuries in liver, lungs and kidney, compared with other groups. However, relieving biliary obstruction could effectively reduce mortality and attenuate liver injury in the SAC mouse model.CONCLUSION Trans-cholecystic injection of LPS under the condition of biliary obstruction could establish a repeatable and reversible mouse model of SAC.

Comparison of intraosseous access and central venous catheterization in Chinese adult emergency patients: A prospective, multicenter, and randomized study

BACKGROUND: It is challenging to establish peripheral intravenous access in adult critically patients. This study aims to compare the success rate of the first attempt, procedure time, operator satisfaction with the used devices, pain score, and complications between intraosseous(IO) access and central venous catheterization(CVC) in critically ill Chinese patients.METHODS: In this prospective clustered randomized controlled trial, eight hospitals were randomly divided into either the IO group or the CVC group. Patients who needed emergency vascular access were included. From April 1, 2017 to December 31, 2018, each center included 12 patients. We recorded the data mentioned above.RESULTS: A total of 96 patients were enrolled in the study. There were no statistically significant differences between the two groups regarding sex, age, body mass index, or operator satisfaction with the used devices. The success rates of the first attempt and the procedure time were statistically significant between the IO group and the CVC group(91.7% vs. 50.0%, P<0.001;52.0 seconds vs. 900.0 seconds, P<0.001). During the study, 32 patients were conscious. There was no statistically significant difference between the two groups regarding the pain score associated with insertion. There were statistically significant differences between the two groups regarding the pain score associated with IO or CVC infusion(1.5 vs. 0.0, P=0.044). Complications were not observed in the two groups.CONCLUSIONS: IO access is a safe, rapid, and effective technique for gaining vascular access in critically ill adults with inaccessible peripheral veins in the emergency departments.

Clinical Application of Newborn Umbilical Vein Catheterization Combining with PICC

Purpose: Research on clinical application effect of combining very low birth weight newborn (VLBWN) umbilical vein catheterization (UVC) with peripherally inserted central catheter (PICC). Method: 60 cases of VLBWN checked in our hospital’s ICU are selected and divided into combination group (n = 30) and PICC group (n = 30) according to the random number table. Combination of UVC and PICC is applied on newborn of combination group while only PICC is applied on newborn of PICC group. These two groups’ newborn’s PICC catheterization operation time, PICC indwelling time, weight gain, hospital stays, hospital infection, planned extubation, successful single puncture, adverse events and other indexes are observed. Result: Newborns in combination group have less PICC catheterization operation time and less hospital stays than newborns in PICC group while newborns in combination group have longer PICC indwelling time and greater weight gain than newborns in PICC group. The difference here has statistical significance (p < 0.05). Combination group’s hospital infection ratio (3.33%) is lower than that of PICC group (23.33%). The difference here has statistical significance (p < 0.05). Newborns in combination group have a planned extubation rate of 93.33% and a successful single puncture rate of 93.33%, which are greater than those of newborn in PICC group (respectively 73.33% and 70.00%). The difference here has statistical significance (p < 0.05). Newborns in combination group have an adverse event occurrence rate of 43.33%, lower than that of PICC group (70.00%). The difference here has statistical significance (p < 0.05). Conclusion: Application of combination of UVC and PICC on VLBWN can greatly improve PICC catheterization efficiency and newborn patients’ nutriture and reduce rate of complications, thus, it is worthy of clinical application.

Bladder perforation caused by long-term catheterization misdiagnosed as digestive tract perforation:A case report

BACKGROUND Spontaneous bladder rupture is relatively rare,and common causes of spontaneous bladder rupture include bladder diverticulum,neurogenic bladder dysfunction,gonorrhea infection,pelvic radiotherapy,etc.Urinary bladder perforation caused by urinary catheterization mostly occurs during the intubation process.CASE SUMMARY Here,we describe an 83-year-old male who was admitted with 26 h of middle and upper abdominal pain and a history of long-term catheterization.Physical examination and computed tomography of the abdomen supported the diagnosis of diffuse peritonitis,most likely from a perforated digestive tract organ.Laparoscopic exploration revealed a possible digestive tract perforation.Finally,a perforation of approximately 5 mm in diameter was found in the bladder wall during laparotomy.After reviewing the patient's previous medical records,we found that 1 year prior the patient underwent an ultrasound examination showing that the end of the catheter was embedded into the mucosal layer of the bladder.Therefore,the bladder perforation in this patient may have been caused by the chronic compression of the urinary catheter against the bladder wall.CONCLUSION For patients with long-term indwelling catheters,there is a possibility of bladder perforation,which needs to be dealt with quickly.

Effects of oral premedication on cognitive status of elderly patients undergoing cardiac catheterization

Background Sedatives and analgesics are often administered to achieve conscious sedation for diagnostic and therapeutic procedures. Appropriate concerns have been raised regarding post procedure delirium related to peri-procedural medication in the elderly. The objective of this study was to investigate the effect of premedication on new onset delirium and procedural care in elderly patients. Methods Patients 〉 70 years old and scheduled for elective cardiac catheterization were randomly assigned to receive either oral diphenhydramine and diaze- pam （25 rag/5 mg） or no premedication. All patients underwent a mini mental state exam and delirium assessment using confusion assess- ment method prior to the procedure and repeated at 4 h after the procedure and prior to discharge. Patients＇ cooperation during the procedure and ease of post-procedure were measured using Visual Analog Scale （VAS）. The degree of alertness was assessed immediately on arrival to the floor, and twice hourly afterwards using Observer＇s Assessment of Alermess/Sedation Scale （OAA/S）. Results A total of 93 patients were enrolled. The mean age was 77 years, and 47 patients received premedication prior to the procedure. None of the patients in either group developed delirium. Patients＇ cooperation and the ease of procedure was greater and pain medication requirement less both during and after the procedure in the pre-medicated group （P 〈 0.05 for both）. Nurses reported an improvement with patient management in the pre-medicated group （P = 0.08）. Conclusions In conclusion, prcmedication did not cause delirium in elderly patients undergoing cardiac catheterization. The reduced pain medication requirement, perceived procedural ease and post procedure management favors premedication in elderly patients undergoing cardiac catheterization.

Efficacy and safety of distal radial approach for cardiac catheterization: A systematic review and meta-analysis

BACKGROUND The traditional radial approach(RA)is recommended as the standard method for coronary angiography(CAG),while a distal RA(DRA)has been recently used for CAG.AIM To assess the efficacy and safety of the DRA vs RA during CAG.METHODS The following databases were searched through December 2020:MEDLINE,the Cochrane Central Register of Controlled Trials,EMBASE,the World Health Organization International Clinical Trials Platform Search Portal,and Clinical-Trials.gov.Individual randomized-controlled trials for adult patients undergoing cardiac catheterization were included.The primary outcomes were the successful cannulation rate and the incidence of radial artery spasm(RAS)and radial artery occlusion(RAO).Study selection,data abstraction and quality assessment were independently performed using the Grading of Recommendations,Assessment,Development,and Evaluation approach.RESULTS Three randomized control trials and 13 registered trials were identified.The two approaches showed similar successful cannulation rates[risk ratio(RR)0.90,95%confidence interval(CI):0.72-1.13].The DRA did not decrease RAS(RR 0.43,95%CI:0.08-2.49)and RAO(RR 0.48,95%CI:0.18-1.29).Patients with the DRA had a shorter hemostasis time in comparison to those with the RA(mean difference-6.64,95%CI:-10.37 to-2.90).The evidence of certainty was low.CONCLUSION For CAG,the DRA would be safer than the RA with comparable cannulation rates.Given the limited data,additional research,including studies with standard protocols,is necessary.

Percutaneous transhepatic portal catheterization guided by ultrasound technology for islet transplantation in rhesus monkey

BACKGROUND:Pig islet xenotransplantation has the potential to overcome the shortage of donated human islets for islet cell transplantation in type 1 diabetes.Testing in nonhuman primate models is necessary before clinical application in humans.Intraportal islet transplantation in monkeys is usually performed by surgical infusion during laparotomy or laparoscopy.In this paper,we describe a new method of percutaneous transhepatic portal catheterization(PTPC) as an alternative to current methods of islet transplantation in rhesus monkeys.METHODS:We performed ultrasound-guided PTPC in five adult rhesus monkeys weighing 7-8 kg,with portal vein catheterization confirmed by digital subtraction angiography.We monitored for complications in the thoracic and abdominal cavity.To evaluate the safety of ultrasound-guided PTPC,we recorded the changes in portal pressure throughout the microbead transplantation procedure.RESULTS:Ultrasound-guided PTPC and infusion of 16 000 microbeads/kg body weight into the portal vein was successful in all five monkeys.Differences in the hepatobiliary anatomy of rhesus monkeys compared to humans led to a higher initial complication rate.The first monkey died of abdominal hemorrhage 10 hours post-transplantation.The second suffered from a mild pneumothorax but recovered fully after taking only conservative measures.After gaining experience with the first two monkeys,we decreased both the hepatic puncture time and the number of puncture attempts required,with the remaining three monkeys experiencing no complications.Portal pressures initially increased proportional to the number of transplanted microbeads but returned to preinfusion levels at 30 minutes post-transplantation.The changes in portal pressures occurring during the procedure were not significantly different.CONCLUSIONS:Ultrasound-guided PTPC is an effective,convenient,and minimally invasive method suitable for use in non-human primate models of islet cell transplantation provided that care is taken with hepatic puncture.Its advantages must be weighed against the risks of procedure-related complications.

Development and validation of a risk prediction model for repeated indwelling urinary catheterization in patients with cervical cancer after surgery

Objective:To study the factors influencing secondary indwelling catheterisation after cervical cancer surgery and to develop a predictive risk model.Methods:A total of 260 patients in a tertiary hospital in Chongqing were selected from January 2020 to December 2021 via convenience sampling.Relevant information of patients was recorded,including age;body mass index;history of hypertension and diabetes,bladder dysfunction,postoperative urinary retention,and postoperative urinary tract infection;Histology;staging;surgical approach;Operation time;Time of first remove of catheter;indwelling catheter days;Hospitalization days.Least absolute shrinkage and selection operator was used to reduce dimensionality and select patient characteristics,and multivariate analysis was performed based on the selected variables.Based on the outcome of analysis,a line chart model was developed for predicting the risk of secondary catheterization in patients with indwelling catheterization after radical cervical cancer surgery.The coefficient of conformity index(C-index)and calibration curves were used to evaluate the accuracy and fit.The model was internally validated via bootstrapping(1000 random samples),and the clinical utility of the model was assessed via decision curve analysis(DCA).Results:Four characteristic variables were selected,including preoperative bladder function,postoperative urinary tract infection,surgical approach,and Time of first remove of catheter.They are independent risk factors affecting urinary tract.The risk prediction model exhibited good discrimination performance with a C-index of 0.722(95%CI,0.661-0.783)and was well calibrated.The C-index was 0.708 in internal validation analysis.DCA showed that the risk model was clinically useful for predicting secondary catheterization,and clinical benefits were observed at the decision threshold of≥11%.Conclusion:A novel model was developed to predict the risk of secondary catheterization.The model was based on preoperative bladder dysfunction,postoperative urinary tract infection,surgical approach,and number of days since the removal of the primary catheter.

Knowledge and Practices among Nurses Regarding Patients’ Care Following Cardiac Catheterization at a Tertiary Care Hospital in Karachi, Pakistan

Aims: The purpose of this study was to assess the knowledge and practices among nurses regarding patient care, following cardiac catheterization, at a tertiary care hospital in Karachi, Pakistan. Background: Cardiovascular diseases (CVDs) are the major cause of morbidity and mortality, globally. Nurses are the largest body of health care professionals who attempt to reduce the burden of cardiovascular diseases. Design: This study employed a descriptive analytical cross-sectional study design to answer the research questions. Methodology: The data were collected from 70 participants using two instruments. Knowledge was assessed through a 50-multiple-choice questions-based questionnaire, whereas, to assess the practices, an observational checklist was utilized which comprised of 20 components. Findings: The majority of the nurses, 54.3%, had adequate, 40% nurses had inadequate, and only 5.7% nurses had excellent knowledge scores. Moreover, 87.1% nurses were observed as carrying out unsatisfactory practices, whereas, only 12.9% nurses were found carrying out satisfactory practices. Conclusion: Since variation in the practices was observed in each of the department, therefore, there is a need for further research, to assess nurses’ attitudes through a qualitative approach and to develop and implement a standard post-cardiac catheterization care protocol.

Bladder perforation injury after percutaneous peritoneal dialysis catheterization:A case report

BACKGROUND Insertion of a catheter into the bladder is a rare complication of peritoneal dialysis(PD),and is mainly related to surgical injury.This paper reports a case of bladder perforation that was caused by percutaneous PD catheterization.CASE SUMMARY A 64-year-old man underwent percutaneous PD catheterization for end-stage renal disease.On the second day after the operation,urgent urination and gross hematuria occurred.Urinalysis showed the presence of red and white blood cells.Empirical anti-infective treatment was given.On the third day after the operation,urgent urination occurred during PD perfusion.Ultrasound showed that the PD catheter was located in the bladder,and subsequent computed tomography(CT)showed that the PD catheter moved through the anterior wall into the bladder.The PD catheter was withdrawn from the bladder and catheterization was retained.Repeat CT on the fourth day after the operation showed that the PD catheter was removed from the bladder,but there was poor catheter function.The PD catheter was removed and the patient was changed to hemodialysis.CT cystography showed that the bladder healed well and the patient was discharged 14 d after the operation.CONCLUSION Bladder perforation injury should be considered and treated timeously in case of bladder irritation during and after percutaneous PD catheterization.The use of Doppler ultrasound and other related technologies may reduce the incidence of such complications.

Carotid Artery Cut-Down in Pediatric Cardiac Catheterization: When and How?

Background:Vascular access used for pediatric cardiac catheterization is one of the most important factors that affects the success of the procedure.We aimed to compare the effect,success,and complications of cardiac catheterizations performed by carotid cut-down or femoral puncture in newborns or young infants.Methods:We included who underwent catheterization in our department between 28 January 2017 and 15 April 2021.These patients underwent balloon aortic valvuloplasty,balloon coarctation angioplasty,ductal stenting,diagnostic procedures for aortic arch pathologies,and modified Blalock-Taussig in-shunt intervention.Patients were divided into two groups:femoral puncture(group=1)and carotid cut-down(CC,group=2).Results:Seventy-two catheterization procedures were performed in 64 patients;32(44.4%)were performed via the femoral approach and 40(55.6%)were performed via the carotid approach.Sixteen(22.2%)procedures were diagnostic and 56(77.8%)procedures were interventional.CC was performed in 13(32.5%)patients with failed femoral intervention.Patients in the CC group had shorter durations of procedure,vascular access,and anesthesia,compared with the femoral access group(80.9 and 116.2 min,p=0.001;12.9 and 22.5 min,p=0.001;140.9 and 166.6 min,p=0.001,respectively).Patients who underwent CC had fewer complications than did patients in the femoral access group(2.5%and 21.8%,respectively;p=0.01);larger sheats were used in CC patients(p=0.028).Conclusion:The carotid artery can be successfully used as a primary catheterization route,particularly in patients with small body weight and patients who require rapid vascular access,or stenting of the vertical duct.

C-peptide increase in chronic type 1 diabetic patients treated with autologous bone marrow cell transplantation through pancreatic artery catheterization: Three years follow-up

Background: Recent extensive clinical evidence demonstrated that autologous adult stem cell therapy was safe and effective as a treatment strategy for type 1 diabetes. Our initial work was designed to examine the safety and efficacy of the implantation technique on 20 subjects with six months of evolution. This new report analyzes the results from three years follow up. Methods: With the authorization from the Ministry of Health of Argentina, 20 subjects with type 1 diabetes were treated with single autologous bone marrow cell transplantation into pancreatic blood flow through pancreatic artery catheterization immediately after bone marrow aspiration. The primary endpoint was defined as normalization of C-peptide and glycated hemoglobin (HbA1c) with insulin independence at 3 years posttreatment. Results: 15 subjects (75%) achieved clinical improvements. 7 subjects (33%) reached the primary endpoint, in which 4 subjets with decreased C-peptide levels required insulin administration again at 3 years post-treatment. Other 8 subjects (34%) showed partial function at 3 years post-treatment. There were no serious adverse events observed. No increases of islet cell antibody (ICA) and glutamic acid decarboxylase (GAD) antibody. Conclusion: This procedure may be a safe and effective treatment for chronic type 1 diabetes. The follow-up results showed a significant increase of the pancreatic secretion of C-peptide and a decrease in the daily dose of exogenous insulin. This effect partially disappears by the three years follow-up without an increase of the level of the ICA and GAD antibodies.

Non-Infectious Complications of Non-Tunneled Central Venous Catheterization for Hemodialysis: Incidence and Reasons in Ouagadougou (Burkina Faso)

Goal: Evaluate the importance and reasons of non-infectious complications of non-tunneled central venous catheterization in our hemodialysis unit. Patients and methods: The study, a prospective type, was conducted in the department of nephrology and hemodialysis of Yalgado Ouedraogo University Hospital Center (YO-UHC) in Ouagadougou, Burkina Faso, from 15 February to 30 June 2015. Patients in whom a new central venous catheter (CVC) was inserted during the study period were included. Catheterization-related complications were noted. Results: During the study period, 156 CVCs (9 per week) were placed in femoral (56.4%), internal jugular (40.4%) or subclavian vein (3.2%). There were 114 patients (59.7% of men and 40.3% of women), average age 41.8 ± 17.1 years, low socio-economic level in 64% of cases. At least a non-infectious complication was observed in 67 cases representing 42.9%. They were: puncture failure (40%), arterial puncture (12.2%), puncture of the thoracic duct (1.3%), pneumothorax (1.3%), bleeding related to the catheter insertion (5.8%), hematoma (1.3%), opposite direction (0.6%), dysfunction of the CVC (10.3%), femoralthrombophlebitis (3.2%). Conclusion: Non-infectious complications of non-tunneled central venous catheterization in our hemodialysis unit were frequent and sometimes severe. Their common denominator was the absence of ultrasound guidance. Our study reaffirms the need for equipping with Doppler ultrasound in our hemodialysis units, even in developing countries, for better security of the patient during central venous catheterization.

The Transradial Approach for Cardiac Catheterization and Percutaneous Coronary Intervention:A Review

Cardiac catheterization and percutaneous coronary intervention play an important role in the management of coronary artery disease.Although the transfemoral approach has been the traditionally dominant method,there has been an increased utilization of the transradial approach.Multiple observational studies and randomized clinical trials have shown fewer bleeding complications,reduced morbidity and mortality,improved quality of life,and better economic outcomes when the transradial approach is utilized when compared to the transfemoral approach.Despite its many benefits,utilization of this approach in certain countries including the United States has been less than optimal due to a lower adoption rates mostly driven by lack of training opportunities and decreased awareness of clinical benefits of the transradial approach.In this review,the history,observational trends,efficacy,and technical aspects of transradial cardiac catheterization and percutaneous coronary intervention are discussed.
