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.

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.

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.

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.

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.

Emphysematous thrombophlebitis caused by a misplaced central venous catheter: A case report

BACKGROUND Central venous catheters(CVCs)often cause life-threatening complications,especially CVC-related bloodstream infection(CVC-BSI)and catheter-related thrombosis(CRT).Here,we report an unusual case of misplaced CVC-induced emphysematous thrombophlebitis,a rare but potentially lethal form of CRT and CVC-BSI characterized by both thrombosis and gas formation.CASE SUMMARY A 48-year-old male presented to the emergency room of a local hospital with sudden-onset headache and coma for 4 h.Computed tomography(CT)revealed right basal ganglia hemorrhage,so emergency decompressive craniotomy was performed and a CVC was inserted through the right subclavian vein for fluid resuscitation during anesthesia.Two days later,the patient was transferred to the intensive care unit of our hospital for further critical care.On day 9 after CVC insertion,the patient suddenly developed fever and hypotension.Point-of-care ultrasound(POCUS)demonstrated thrombosis and dilatation of the right internal jugular vein(IJV)filled with thrombosis.Ultrasonography also revealed that the CVC tip had been misplaced into the IJV and was surrounded by gas bubbles,which manifested as hyperechoic lines with dirty shadowing and comet-tail artifacts.Further CT scan confirmed air bubbles surrounding the CVC in the right neck.The final diagnosis was septic emphysematous thrombophlebitis induced by a misplaced CVC and ensuing septic shock.The responsible CVC was removed immediately.The patient received fluid resuscitation,intravenous noradrenaline,and a 10-d ultra-broad spectrum antibiotic treatment to combat septic shock.Both CVC and peripheral venous blood cultures yielded methicillin-resistant Staphylococcus cohnii.The patient was gradually weaned off vasopressors and the symptoms of redness and swelling in the right neck subsided within 7 d.CONCLUSION Emphysematous thrombophlebitis is a fulminant and life-threatening CVC-BSI associated with thrombosis and gas formation in the vein.A misplaced CVC may facilitate the development of emphysematous thrombophlebitis.POCUS can easily identify the artifacts produced by gas and thrombosis,facilitating rapid diagnosis at the bedside.

Clinical Study of Aspirin in the Prevention of Thrombosis in Breast Cancer Patients with Postoperative Chemotherapy after PICC Insertion

Objective: To study the clinical effect of aspirin in the prevention of venous thrombosis in breast cancer patients with postoperative chemotherapy after peripherally inserted central catheter (PICC) insertion. Methods: 240 cases of female breast cancer patients with postoperative chemotherapy after PICC insertion in The First People’s Hospital of Jingzhou from June 2014 to December 2017 were selected and divided into experimental group (n = 120) and control group (n = 120) according to the length of stay. The modified Seldinger technique was used in both groups. The experimental group had oral Aspirin enteric-coated tablet on the day of PICC insertion, 100 mg/day until the PICC catheter was removed, while the control group did not take anticoagulant drugs. The therapeutic effects were evaluated by color Doppler ultrasound, Coagulation analysis, and complete blood count. Results: There were three cases with venous thrombosis in the experimental group, and the incidence rate was 2.5%, while ten cases in the control group developed venous thrombosis, and the incidence rate was 10%. There was a statistically significant difference in the incidence of thrombosis between the two groups (P Conclusion: This study showed that oral Aspirin can effectively reduce the incidence rate of venous thrombosis in breast cancer patients with postoperative chemotherapy after PICC insertion. Therefore, it is worthy of clinical application.

Economic Analysis of Port and PICC in Long-term Intravenous Administration for Malignant Tumor Patients in Chinese Oncology Hospital Setting

OBJECTIVE: To calculate and compare the cost of Port and PICC's application in long-term intravenous administration, and to support the decision making of hospital manager. METHODS: Literature review and patient survey in 2 oncology centers in China were carried out to investigate the cost and impact of Port and PICC for patients. The cost at different time of intravenous administration was calculated and compared. One-way sensitivity analysis was performed and tornado graph was drawn. RESULTS: Direct cost of Port at 0.5, 1, 1.5, and 2 years were7442, 8005, 8553, and 9131 CNY, and 4700, 9399, 14032, 18799 CNY for PICC respectively. Direct & indirect cost at 0.5, 1, 1.5, and 2 years were 9291, 11704, 14101, 16529 CNY for Port and 9697, 19393, 29023, 38787 CNY for PICC. Sensitivity analysis showed that productivity loss and device maintenance cost were the most in?uential factors to the result. CONCLUSION: Port had higher cost in short term and less in long term compared with PICC. Patients expected to get intravenous administration more than 0.5 year should use Port if both direct and indirect costs were included.

Venous thromboembolism in patients with liver cancer:a retrospective study

Background:Little is known about the association between venous thromboembolism(VTE)and tumors.In this study,we identified the clinical features of patients with liver cancer who presented with at least 1 VTE episode.Methods:This was a retrospective case-control study of a single-institution database with univariate and multivariate analyses usingχ^(2)and Fisher exact tests.Statistical significance was set at P<0.05.Results:The overall incidence of VTE in the patients with liver cancer was 1.2%.More than half(53.8%)of the 13 patients with liver cancer and venous thrombosis died within 2 months.The thrombus in 12 patients(92.3%)was located within the deep veins,whereas the other patient(7.7%)was diagnosed with a pulmonary embolism.Of the 11 patients,9(69.2%)had swelling and/or pain symptoms.All 6 patients with peripherally inserted central catheters(PICCs)had thrombosis,accounting for 46.2%of all patients with liver cancer and venous thrombosis.Compared with the controls,liver cancer patients with PICC tubes,thrombosis-related symptoms such as swelling and pain,traumatic stimulation such as fracture,acute respiratory distress syndrome,and interventional therapy or hemostasis drugs were prone to be diagnosed with VTE(P<0.05).Conclusions:Liver cancer and thrombosis are rare and have poor prognoses.Liver cancer with thrombosis may be associated with PICC catheterization,traumatic stimulation,or hemostatic drugs.Patients with liver cancer and thrombosis often present with swelling and pain.
