Lower extremity peripherally inserted central catheter placement ectopic to the ascending lumbar vein:A case report

BACKGROUND Peripherally inserted central catheters(PICCs)are an essential infusion route for oncology patients receiving intravenous treatments,but lower extremity veni-puncture is the preferred technique for patients with superior vena cava syndrome(SVCS).We report the case of a patient with a lower extremity PICC ectopic to the ascending lumbar vein,to indicate and verify PICC catheterisation in the lower extremity is safe and feasible.And hope to provide different per-spectives for clinical PICC venipuncture to get the attention of peers.CASE SUMMARY On 24 August 2022,a 58-year-old male was admitted to our department due to an intermittent cough persisting for over a month,which worsened 10 d prior.Imaging and laboratory investigations suggested the patient with pulmonary malignancy and SVCS.Chemotherapy was not an absolute contraindication in this patient.Lower extremity venipuncture is the preferred technique because administering upper extremity venous transfusion to patients with SVCS can exacerbate oedema in the head,neck,and upper extremities.The patient and his family were informed about the procedure,and informed consent was obtained.After successful puncture and prompt treatment,the patient was discharged,experiencing some relief from symptoms.CONCLUSION Inferior vena cava catheterisation is rare and important for cancer patients with SVCS,particularly in complex situations involving ectopic placement.

Clues for diagnosing misplaced central venous catheter in the right ascending lumbar vein during right femoral venous access

The right ascending lumbar vein is difficult to detect on anteroposterior abdominalradiographs because it overlaps with the inferior vena cava on anteroposteriorradiographs.Intensive observation by medical providers may be a cue fordiagnosis.However,knowledge of catheter misplacement of the right ascendinglumbar vein is also necessary,because misplacement cannot be suspected withoutthat awareness.

Central venous catheterization-related complications in a cohort of 100 hospitalized patients:An observational study

Objective:To evaluate the complications of central venous catheterization(CVC).Methods:A prospective,observational study was conducted at a tertiary care center in India from December 2018 to September 2020.Critically ill patients(aged≥18 years)in the intensive care unit undergoing CVC procedures were included in the study.Baseline demographics and detailed medical history were recorded.Chest X-rays and electrocardiography were performed on all the patients.Complications associated with CVC were recorded.Results:A total of 100 patients with the indication for central venous catheter insertion were included.The majority(81%)of the patients were inserted with CVC at the right internal jugular vein.Complications such as arterial puncture(2%),hematoma(4%),blood clot formation(4%),catheter kinking(3%),thoracic injury(1%),thrombophlebitis(6%),sepsis(9%)and nerve injury(1%)were reported.Conclusions:Though central venous access is preferred in management of critically ill patients,it has its risks.However,early recognition and prompt management of complications may reduce mortality and morbidity.Physicians and intensive care unit intensivists should be vigilant for central venous catheter-related complications.Suitable site selection,operator experience,and proper catheter maintenance are associated with optimal outcomes.

Clinical analysis of central venous catheter-related infections in patients in the emergency ICU

BACKGROUND:Catheter-related infection(CRI)of the central vein is a common cause of nosocomial infection.This study was undertaken to investigate the pathogen culturing and risk factors of CRI in emergency intensive care unit(EICU)in order to provide the beneficial reference.METHODS:From January 2008 to December 2010,a total of 1 363 patients were subjected to catheterization.In these patients,the peak CRI rate of the patients was determined by bacterial cultivation and blood bacterial cultivation.RESULTS:CRI happened in 147 of the 1 363 patients using the central venous catheter.The peak rate of CRI was 10.79%,with an incidence of 3.05 episodes per 1 000 catheter days.Of the147 patients,46.94%had gram-negative bacilli,40.14%had gram-positive cocci,and 12.92%had fungi.Unconditional logistic regression analysis suggests that multiple catheterization,femoral vein catheterization,the application of multicavity catheter,and the duration of catheterization were the independent risk factors for CRI.CONCLUSION:The risk factors for catheter-related infections should be controlled to prevent the occurrence of nosocomial infection.

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.

Thoracic duct cannulation during left internal jugular vein cannulation:A case report

BACKGROUND Central venous catheter insertion is an invasive procedure that can cause complications such as infection,embolization due to air or blood clots,pneumothorax,hemothorax,and,rarely,chylothorax due to damage to the thoracic duct.Herein,we report a case of suspected thoracic duct cannulation that occurred during left central venous catheter insertion.Fortunately,the patient was discharged without any adverse events related to thoracic duct cannulation.CASE SUMMARY A 46-year-old female patient presented at our department to undergo cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.During anesthesia,we decided to insert a central venous catheter through the left internal jugular vein because the patient already had a chemoport through the right central vein.During the procedure,blood reflux was observed when the needle tip was not within the ultrasound field of view.We did not try to find the tip;however,a guide wire and a central venous catheter were inserted without any resistance.Subsequently,when inducing blood reflux from the distal port of the central venous catheter,only clear fluid,suspected to be lymphatic fluid,was regurgitated.Further,chest X-ray revealed an appearance similar to that of the path of the thoracic duct.Given that intravenous fluid administration was not started and no abnormal fluid collection was noted on preoperative chest X-ray,we suspected thoracic duct cannulation.CONCLUSION It is important to use ultrasound to confirm the exact position of the needle tip and guide wire path.

Upper body peripherally inserted central catheter in pediatric single ventricle patients

BACKGROUND There is risk of stenosis and thrombosis of the superior vena cava after upper extremity central catheter replacement.This complication is more serious among patients with single ventricle physiology,as it might preclude them from undergoing further life-sustaining palliative surgery.AIM To describe complications associated with the use of upper extremity percutaneous intravenous central catheters(PICCs)in children with single ventricle physiology.METHODS A single institution retrospective review of univentricular patients who underwent superior cavopulmonary anastomoses as their stage 2 palliation procedure from January 2014 until December 2018 and had upper body PICCs placed at any point prior to this procedure.Clinical data including ultrasonography,cardiac catheterization,echocardiogram reports and patient notes were used to determine the presence of thrombus or stenosis of the upper extremity and cervical vessels.Data regarding the presence and duration of upper extremity PICCs and upper extremity central venous catheter(CVC),and use of anticoagulation were recorded.RESULTS Seventy-six patients underwent superior cavopulmonary anastomoses,of which 56(73%)had an upper extremity PICC at some point prior to this procedure.Median duration of PICC usage was 24 d(25%,75%:12,39).Seventeen patients(30%)with PICCs also had internal jugular or subclavian central venous catheters(CVCs)in place at some point prior to their superior cavopulmonary anastomoses,median duration 10 d(25%,75%:8,14).Thrombus was detected in association with 2 of the 56 PICCs(4%)and 3 of the 17 CVCs(18%).All five patients were placed on therapeutic dose of low molecular weight heparin at the time of thrombus detection and subsequent cardiac catheterization demonstrated resolution in three of the five patients.No patients developed clinically significant venous stenosis.CONCLUSION Use of upper extremity PICCs in patients with single ventricle physiology prior to super cavopulmonary anastomosis is associated with a low rate of catheterassociated thrombosis.

Massive hemothorax following internal jugular vein catheterization under ultrasound guidance:A case report

BACKGROUND Hemothorax is a rare but life-threatening complication of central venous catheterization.Recent reports suggest that ultrasound guidance may reduce complications however,it does not guarantee safety CASE SUMMARY A 75-year-old male patient was admitted for laparoscopic radical nephrectomy.Under ultrasound guidance,right internal jugular vein catheterization was successfully achieved after failure to aspirate blood from the catheter in the first attempt.Sudden hypotension developed after surgical positioning and persisted until the end of the operation,lasting for about 4 h.In the recovery room,a massive hemothorax was identified on chest radiography and computed tomography.The patient recovered following chest tube drainage of 1.6 L blood.CONCLUSION Hemothorax must be suspected when unexplained hemodynamic instability develops after central venous catheterization despite ultrasound guidance.So the proper use of ultrasound is important.

Analysis of Use and Outcomes of Peripherally Inserted Central Catheter (PICC-Line) in Hemato-Oncological Patients

Aims: To audit the use and outcomes of using PICC lines in hemato-oncological patients. Objectives: To study the demographics of patients: ?studying the use of PICC line in hemato-oncological patients;studying the rate of complications in PICC line;studying the cause of early removal of PICC line. Methods: All PICCs inserted in adult hemato-oncological patients in Hematology and Medical Oncology Department of Health Care Global (HCG) Hospital were studied prospectively, as per the proforma, till PICCs were removed or patient expired and the pattern of complications were noted. Results: Eighty-four PICCs were inserted over a period of initial nine months and followed for a total of 1 year with three months post insertion duration for a total of 10,868 catheter-days (mean of 129 days i.e. 4.3 months, range: 1 to 288 days). The most common indication for PICC was chemotherapy (100%). Among them 19 (22%) PICCs had complications and 12 were removed at the rate of 1.1/1000 PICC-days. Complications with haematologic malignancies were more as compared to those with solid tissue malignancies. Conclusions: Despite significant complication rates, PICCs are a relatively safe and cost effective mode of establishing central venous access.
