Project description:BackgroundThere is still no reference standard for the implantation of totally implantable venous access ports (TIVAPs). A recently published multicentre randomised controlled trial (RCT) revealed a significantly greater risk of pneumothorax after closed cannulation than after an open strategy. The aim of this meta-analysis was to provide an update of the available evidence for the safety and effectiveness of primary open versus closed cannulation strategy.MethodsRCTs comparing outcomes of open cut-down of the cephalic vein and closed cannulation of the subclavian vein were sought systematically in MEDLINE, Web of Science and CENTRAL. The primary outcome was the occurrence of pneumothorax. A beta-binominal model was applied to combine the respective outcomes, and results are presented as odds ratios (OR) with 95% confidence interval (CI).ResultsSix RCTs with a total of 1831 patients were included in final analysis. Meta-analysis showed statistically significant superiority of the open cut-down technique regarding pneumothorax (OR 0.308, 95% CI 0.122 to 0.776), but a statistically significant higher failure of the primary technique for the open cut-down technique than for closed cannulation (OR 2.364, 95% CI 1.051 to 5.315). There were no significant differences between the two procedures regarding other morbidity endpoints.ConclusionThis meta-analysis shows a general superiority of open cut-down of the cephalic vein over closed cannulation of the subclavian vein regarding the occurrence of pneumothorax. Open cut-down should be the first-line approach for TIVAP implantation. Closed cannulation should be performed with ultrasound as second-line procedure if the open technique fails.Systematic review registrationPROSPERO CRD42013005180.

Project description:PurposeLong-term totally implantable venous access ports (TIVAP) are essential for administering chemotherapy and parenteral nutrition in cancer patients. This study aimed to evaluate patient satisfaction and postoperative complications, compared to existing literature, emphasizing patient-reported outcomes (PRO) as a critical factor in treatment decisions.MethodsA prospective, monocentric observational study included 149 patients requiring TIVAP between April 13 and August 17, 2022. Patient satisfaction was assessed using a questionnaire covering four domains: overall satisfaction, willingness to choose the port again, cosmetic result, and pain experience. A meta-analysis of seven studies (1,035 patients) was performed to establish baseline data. The study assumed a non-inferiority margin of 12 points on a 0-100 scale (lower scores indicating better outcomes). Follow-ups were carried out at four weeks and six months.ResultsOf the 149 patients (mean age 58.8 years, 96% with oncological diseases), 117 (78.5%) TIVAPs were implanted via the cut-down technique, primarily using the cephalic vein (84.6%). Out of 1,240 documented catheter accesses, 91.4% were complication-free. Satisfaction scores demonstrated non-inferiority across all domains compared to literature: overall satisfaction (18.5 vs. 35.6; p < 0.001), willingness to choose the port again (15.8 vs. 29.4; p < 0.001), cosmetic result (38.0 vs. 39.9; p = 0.003), and pain experience (17.1 vs. 31.5; p < 0.001).ConclusionThe study demonstrated adequate patient satisfaction and non-inferiority of the investigated TIVAP system compared to other systems, though no superiority was found in cosmetic outcomes.

Project description:A totally implantable venous access port (TIVAP) is important in children who need intravenous infusion for a long time. A number of studies have shown methods for locating the tip of the TIVAP catheter. To explore whether transesophageal echocardiography (TEE) can be used to accurately locate the TIVAP catheter tip through a subclavian approach and to improve the rate of correct TIVAP catheter placement and reduce complications of TIVAP placement. In 36 children who needed TIVAP implantation surgery, we used real-time TEE guidance to place the catheter tip around the crista terminalis. In all children, chest X-rays were used to figure out whether the catheter tip as localized by TEE was within the T5-T7 segment. Then, we compared the length of the catheter calculated by the height formula and the actual catheter length applied under TEE guidance. The medical records, surgical details, nursing records, and recorded complications were collected during the follow-up. The success rate of TIVAP implantation was 100% in all enrolled patients and no hemopneumothorax or pinch-off syndrome occurred. Compared with TEE, chest X-ray showed a coincidence rate of 80.56% in correctly detecting the TIVAP catheter tip locate. The height-derived catheter length (11.0 [9.6, 11.8]) cm and the TEE-derived catheter length (10.0 [9.3, 10.8]) cm were significantly different (p < .001). TEE can be used to guide TIVAP catheter positioning through a left subclavian approach in children accurately and successfully and more accurate than chest X-ray and height calculation formula.

Project description:IntroductionKnowledge of effects of catheter port reversal (CathPR), when blood is withdrawn from the venous port and returned via the arterial port, often used in dysfunctional catheters in renal replacement therapy, is limited in the setting of citrate continuous veno-venous hemofiltration (CVVH).MethodsIn this open trial, post-filter ionized calcium (PfiCa), post-filter citrate concentration (PfCC), catheter recirculation, and solute clearance were measured before, during, and after 6 hours of CathPR, in well-functioning catheters. All other settings, including citrate settings, were left constant during the study.ResultsTwenty-three patients were included. Mean PfiCa before CathPR of 0.36 mmol/L (SD 0.06) decreased to 0.31 (0.04) after 2 hours (P = 0.002), 0.31 (0.04) (P = 0.002) at 4 hours, and 0.31 (0.04) at 6 hours (P = 0.001). Return to normal increased mean PfiCa to 0.34 (0.06) (P = 0.006). Mean PfCC rose from 592 mg/L (SD 164) before CathPR to 649 mg/L (190) after 2 hours (P = 0.045), to 696 mg/L (192) after 4 hours (P < 0.001), and to 657 mg/L (214) after 6 hours (P = 0.018). Return to normal decreased mean PfCC to 598 mg/L (184) (P = 0.024). Mean recirculation increased during CathPR (from 4.3% [0-8.7] before to 13.8% [9.7-22.2], P < 0.001). Urea, potassium, and creatinine clearances dropped significantly, but calcium clearance was unaffected.ConclusionCathPR caused a significant decrease in PfiCA and increase in PfCC. Calcium handling differs from other solutes because of increases caused in citrate concentration and subsequent effects on calcium chelation. In citrate CVVH, CathPR in dysfunctional catheters should be limited in time, with intensive follow-up. Trial registration: ClinicalTrials.gov: NCT024600416. Registered 9 November 2015.

Project description:Background and aimNinety-four thousand gynecological cancer diagnoses are performed each year in the United States. The majority of these tumors require systemic adjuvant therapy. Sustained venous access was overcome by indwelling long-term central venous catheter (CVC). The best choice of which CVC to use is often arbitrary or dependent on physician confidence. This meta-analysis aims to compare PORT and peripherally inserted central catheter (PICC) outcomes during adjuvant treatment for gynecological cancer.MethodsMeta-analysis Of Observational Studies in Epidemiology (MOOSE) and the preferred reporting items for systematic reviews and meta-analyses statement (PRISMA)were used to conduct the meta-analysis.Results1320 patients were included, 794 belonging to the PORT group and 526 to the PICC group. Total complication rates were fewer in the PORT group, p = 0.05. CVC malfunction was less frequent in the PORT group than in the PICC group, p <0.01. Finally, thrombotic events were less expressed in the PORT group than in the PICC group, p = 0.02. No difference was found in operative complication, migration, malposition, extravasation, infection, and complication requiring catheter removal.ConclusionsPORT had fewer thrombotic complications and fewer malfunction problems than PICC devices. Unless specific contraindications, PORTs can be preferred for systemic treatment in gynecological cancer patients.

Project description:Totally implantable venous access port (TIVAP) implantation is one of the most often performed operations in general surgery (over 100,000/year in Germany). The two main approaches for TIVAP placement are insertion into the cephalic vein through an open cut-down technique (OCD) or closed cannulation technique of the subclavian vein (CC) with Seldinger technique. Both procedures are performed with high success rates and very low complication frequencies. Because of the low incidence of complications, no single interventional trial is able to report a valid comparison of peri- and postoperative complication frequencies between both techniques. Therefore, the aim of this systematic review is to summarize evidence for peri- and postoperative complication rates in patients undergoing OCD or CC.A systematic literature search will be conducted in The Cochrane Library, MEDLINE, and Embase to identify randomized controlled trials (RCTs), observational clinical studies (OCS), or case series (CS) reporting peri- and/or postoperative complications of at least one implantation technique. A priori defined data will be extracted from included studies, and methodological quality will be assessed. Event rates with their 95% confidence intervals will be derived taking into account the follow-up time per study by patient-months where appropriate. Pooled estimates of event rates with corresponding 95% confidence intervals will be calculated on the base of the Freeman-Tukey double arcsine transformation within a random effect model framework.The findings of this systematic review with proportional meta-analysis will help to identify the procedure with the best benefit/risk ratio for TIVAP implantation. This may have influence on daily practice, and data may be implemented in treatment guidelines. Considering the impact of TIVAP implantation on patients' well being together with its socioeconomic relevance, patients will benefit from evidence-based treatment and health-care costs may also be reduced.PROSPERO CRD42013005180.

Project description:Percutaneous central vascular venous access to allow positioning of a totally implantable access port (TIAP) is a widely employed procedure. An open issue is the need to find an ionizing radiation free technique which allows a safe and correct positioning of the device. Echo-guided vein puncture is currently accepted as the best method for decreasing major immediate complications. We describe an entirely echo-based method for the insertion and assessment of correct placement of the totally implantable access ports (TIAP). 20 TIAPs with the described technique have been placed. TIAP can be safely positioned by entirely echo-guided technique avoiding ionizing radiation imaging.
