Establishment and validation of a predictive model for peripherally inserted central catheter-related thrombosis in patients with liver cancer

BACKGROUND Peripherally inserted central catheters(PICCs)are commonly used in hospitalized patients with liver cancer for the administration of chemotherapy,nutrition,and other medications.However,PICC-related thrombosis is a serious complication that can lead to morbidity and mortality in this patient population.Several risk factors have been identified for the development of PICC-related thrombosis,including cancer type,stage,comorbidities,and catheter characteristics.Understanding these risk factors and developing a predictive model can help healthcare providers identify high-risk patients and implement preventive measures to reduce the incidence of thrombosis.AIM To analyze the influencing factors of PICC-related thrombosis in hospitalized patients with liver cancer,construct a predictive model,and validate it.METHODS Clinical data of hospitalized patients with liver cancer admitted from January 2020 to December 2023 were collected.Thirty-five cases of PICC-related thrombosis in hospitalized patients with liver cancer were collected,and 220 patients who underwent PICC placement during the same period but did not develop PICC-related thrombosis were randomly selected as controls.A total of 255 samples were collected and used as the training set,and 77 cases were collected as the validation set in a 7:3 ratio.General patient information,case data,catheterization data,coagulation indicators,and Autar Thrombosis Risk Assessment Scale scores were analyzed.Univariate and multivariate unconditional logistic regression analyses were performed on relevant factors,and the value of combined indicators in predicting PICC-related thrombosis in hospitalized patients with liver cancer was evaluated using receiver operating characteristic(ROC)curve analysis.RESULTS Univariate analysis showed statistically significant differences(P<0.05)in age,sex,Karnofsky performance status score(KPS),bedridden time,activities of daily living impairment,parenteral nutrition,catheter duration,distant metastasis,and bone marrow suppression between the thrombosis group and the non-thrombosis group.Other aspects had no statistically significant differences(P>0.05).Multivariate regression analysis showed that age≥60 years,KPS score≤50 points,parenteral nutrition,stage III to IV,distant metastasis,bone marrow suppression,and activities of daily living impairment were independent risk factors for PICC-related thrombosis in hospitalized patients with liver cancer(P<0.05).Catheter duration of 1-6 months and catheter duration>6 months were protective factors for PICC-related thrombosis(P<0.05).The predictive model for PICC-related thrombosis was obtained as follows:P predictive probability=[exp(Logit P)]/[1+exp(Logit P)],where Logit P=age×1.907+KPS score×2.045+parenteral nutrition×9.467+catheter duration×0.506+tumor-node-metastasis(TNM)staging×2.844+distant metastasis×2.065+bone marrow suppression×2.082+activities of daily living impairment×13.926.ROC curve analysis showed an area under the curve(AUC)of 0.827(95%CI:0.724-0.929,P<0.001),with a corresponding optimal cut-off value of 0.612,sensitivity of 0.755,and specificity of 0.857.Calibration curve analysis showed good consistency between the predicted occurrence of PICC-related thrombosis and actual occurrence(P>0.05).ROC analysis showed AUCs of 0.888 and 0.729 for the training and validation sets,respectively.CONCLUSION Age,KPS score,parenteral nutrition,TNM staging,distant metastasis,bone marrow suppression,and activities of daily living impairment are independent risk factors for PICC-related thrombosis in hospitalized patients with liver cancer,while catheter duration is a protective factor for the disease.The predictive model has an AUC of 0.827,indicating high predictive accuracy and clinical value.

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.

Focus on peripherally inserted central catheters in critically ill patients

Venous access devices are of pivotal importance for an increasing number of critically ill patients in a variety of disease states and in a variety of clinical settings(emergency, intensive care, surgery) and for different purposes(fluids or drugs infusions, parenteral nutrition, antibiotic therapy, hemodynamic monitoring, procedures of dialysis/apheresis). However, healthcare professionals are commonly worried about the possible consequences that may result using a central venous access device(CVAD)(mainly, bloodstream infections and thrombosis), both peripherally inserted central catheters(PICCs) and centrally inserted central catheters(CICCs). This review aims to discuss indications, insertion techniques, and care of PICCs in critically ill patients. PICCs have many advantages over standard CICCs. First of all, their insertion is easy and safe-due to their placement into peripheral veins of the armand the advantage of a central location of catheter tip suitable for all osmolarity and p H solutions. Using the ultrasound-guidance for the PICC insertion, the risk of hemothorax and pneumothorax can be avoided, as wellas the possibility of primary malposition is very low. PICC placement is also appropriate to avoid post-procedural hemorrhage in patients with an abnormal coagulative state who need a CVAD. Some limits previously ascribed to PICCs(i.e., low flow rates, difficult central venous pressure monitoring, lack of safety for radio-diagnostic procedures, single-lumen) have delayed their start up in the intensive care units as common practice. Though, the recent development of power-injectable PICCs overcomes these technical limitations and PICCs have started to spread in critical care settings. Two important take-home messages may be drawn from this review. First, the incidence of complications varies depending on venous accesses and healthcare professionals should be aware of the different clinical performance as well as of the different risks associated with each type of CVAD(CICCs or PICCs). Second, an inappropriate CVAD choice and, particularly, an inadequate insertion technique are relevant-and often not recognized-potential risk factors for complications in critically ill patients. We strongly believe that all healthcare professionals involved in the choice, insertion or management of CVADs in critically ill patients should know all potential risk factors of complications. This knowledge may minimize complications and guarantee longevity to the CVAD optimizing the risk/benefit ratio of CVAD insertion and use. Proper management of CVADs in critical care saves lines and lives. Much evidence from the medical literature and from the clinical practice supports our belief that, compared to CICCs, the so-called power-injectable peripherally inserted central catheters are a good alternative choice in critical care.

Delayed cardiac tamponade diagnosed by point-of-care ultrasound in a neonate after peripherally inserted central catheter placement: A case report

BACKGROUND Peripherally inserted central catheters(PICCs)have been increasingly applied worldwide owing to many advantages.Even with these advantages,the related complications should not be ignored,especially in neonates.The available evidence about PICC-related thrombosis was manifold,but the cardiac tamponade,an emergency and life-threatening complication,has been rarely reported.Early recognized cardiac tamponade by ultrasound may reduce mortality.CASE SUMMARY A neonate weighting 2.8 kg was born at 40 wk of gestation.He was admitted to the Surgery Intensive Care Unit due to suspected congenital megacolon.A PICC line was inserted via the left antecubital fossa for the administration of total parenteral nutrition.Three days later,the patient was still on total parenteral nutrition.Cardiac tamponade caused by PICC was found on ultrasound.The patient recovered spontaneously after an emergency pericardiocentesis.CONCLUSION Proficiency in the use of point-of-care ultrasound may save the life of patients,since it enables clinicians to treat patients faster,more accurately,and in a noninvasive way at the point of care.

Arterial embolism caused by a peripherally inserted central catheter in a very premature infant:A case report and literature review

BACKGROUND Extremely premature infants have poor vascular conditions.Operators often choose deep veins such as the femoral vein and axillary vein to peripherally insert central catheters,and these vessels are often accompanied by arteries;thus,it is easy to mistakenly enter the artery.CASE SUMMARY The case of an extremely premature infant(born at gestational age 28+3)in whom the left upper extremity artery was accidentally entered during peripheral puncture of the central venous catheter is reported.On the 19th day of hospitalization,the index finger,middle finger and ring finger of the left hand were rosy,the left radial artery and brachial artery pulse were palpable,the recovery was 95%,and the improvement was obvious.At discharge 42 d after admission,there was no abnormality in fingertip activity during the follow-up period.CONCLUSION Arterial embolization in preterm infants requires an individualized treatment strategy combined with local anticoagulation and 2%nitroglycerin ointment for local tissue damage caused by arterial embolism in the upper limb.Continuous visualization of disease changes using image visualization increases the likelihood of a good outcome.

Diagnosis and treatment of peripherally inserted central catheters(PICC)-related sepsis in breast cancer patients carrying PICC catheter for chemotherapy

Objective:The aim of our research was to study the incidence,clinical diagnosis and treatment of peripherally inserted central catheters(PICC)-related sepsis in breast cancer patients carrying PICC catheter for chemotherapy.Methods:The data of the incidence,diagnosis and treatment of PICC-related sepsis in 215 cases of breast cancer patients carrying PICC catheter for chemotherapy in our hospital from August,2009 to September,2011 were analyzed retrospectively.Results:216 PICCs had been successfully applied in 215 cases of breast cancer patients and followed for a total of 19,109 catheter days,(median catheterization duration,88.9 days,range 1-212 days).Among those,3(1.39%) PICCs were removed respectively as a result of PICC-related sepsis in 29,73 and 108 catheter-days(median 70 d),with a rate of 0.16 per 1000 catheter-days.Conclusion:Chemotherapeutic treatment via PICC for breast cancer patients is one of the most secure and effective measures but there exists small number of cases in which PICC catheter related sepsis is possible.Careful observation of relevant symptoms and signs,early diagnosis and treatment,not relying completely on blood culture tests and timely removal of PICC catheter can be very effective in treating PICC-related sepsis in these patients.

An Unusual Peripherally Inserted Central Catheter (PICC) Fractured <i>in Vivo</i>with Embolization Happened in a Child: A Case Report

We report a case of a 7-year-old child who received a peripherally inserted central catheter (PICC) for chemotherapy. He suffered from an unusual PICC fracture in vivo with pulmonary embolism after eight circles of chemotherapeutic agents administered. In this case report, we review the literatures for the underlying pathophysiology of this uncommon phenomenon. IV nurses should consider the possibility of the infusion dysfunction deriving from the PICC line fractured. Accurate tip catheter placement and specific care may reduce morbidity.

Peripherally inserted central catheter placement in neonates with persistent left superior vena cava: Report of eight cases

BACKGROUND Reports on peripherally inserted central catheter(PICC)placement in neonates with persistent left superior vena cava(PLSVC)are rare.The majority of PLSVC patients have no clinical symptoms or hemodynamic changes,which are usually detected during cardiac catheterization,cardiac pacemaker implantation,or PICC placement.However,in neonates with PLSVC,PICC placement can be challenging.Here,we report PICC placement in eight neonates with PLSVC.CASE SUMMARY This article introduces the concept of the“TIMB”bundle.After PICC implantation,we found PLSVC in all eight patients.The key points of care regarding PICC placement in neonates with PLSVC included“TIMB”,where“T”indicates a reasonable choice of the catheterization time,“I”refers to a retrospective analysis of imaging data before catheterization,“M”refers to correct measurement of the body surface length,and“B”indicates that the tip of the PICC is placed in the middle and lower 1/3 of the left superior vena cava under the guidance of B-ultrasound.CONCLUSION“TIMB”is a bundle for PICC placement in neonates,especially for those with PLSVC.Using this new approach can improve the first-attempt success rate of PICC placement,reveal cardiovascular abnormalities in advance,allow the selection of different measurement methods reasonably according to the puncture site,and finally,improve the accuracy of catheter positioning through the use of B-ultrasound guidance.

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.

Tip orientation under real-time point-of-care neck ultrasonic monitoring is advantageous in peripherally inserted central catheter procedures:a retrospective cohort study

Background:We analyzed the success and catheter tip malposition rates of peripherally inserted central catheter(PICC)placement using ultrasonic monitoring.Methods:A total of 564 patients were recruited and assigned to either the intervention or control group.In the intervention group,282 patients underwent ultrasound-guided PICC insertion,which helped to identify the position and depth of the catheter tip.From a total of 9000 patients,282 were selectively chosen to receive the traditional method using body surface measurements(control group).The primary endpoint was the success rate;the secondary endpoint was the catheter tip malposition rate as detected by postprocedure chest radiography.Results:In the intervention group,a total of 94 catheters were in a suboptimal position;26 were too deep,68 were too shallow,and 1 was inserted into the subclavian vein,with success and malposition rates of 66.3%and 0.4%,respectively.In the control group,139 catheters were in a suboptimal position;88 were too deep,51 were too shallow,9 were inserted into the jugular vein,and 2 were inserted into the subclavian vein,with success and malposition rates of 46.8%(P<0.001)and 3.9%(P=0.004),respectively.Significant differences were observed in success and malposition rates between the 2 groups.Conclusion:Ultrasound-guided PICC procedures achieved higher success rates and lower malposition rates.
