Background: Tunneled central venous catheters placed by interventional radiologists are now widely used for hemodialysis and infusion therapies throughout the world. However, complications such as infections and malfunctions still remain a major concern in oncology and hemodialysis patients.
Purpose: To evaluate the long-term follow-up results of tunneled central venous catheters in an adult population in terms of infectious complications and malfunction rates in dialysis and oncology patients.
Material and Methods: We retrospectively reviewed the hospital charts and our electronic database for 434 tunneled internal jugular catheters in 335 consecutive patients between December 2002 and March 2006. Mean patient age was 57 years (range 23-86 years) in the hemodialysis group and 45 years (range 18-83 years) in the infusion group. A total of 224 hemodialysis catheters were placed in 168 patients (68 females, 100 males) and 210 infusion catheters in 167 patients (48 females, 119 males).
Results: Technical success rate was 100%. Mean duration of catheter use was 86 days (1-652 days) and 60 days (2-686 days) for hemodialysis and infusion catheters, respectively. A total of 107 hemodialysis (47%) and 95 infusion catheters (45%) were electively removed due to completion of therapy and resolution of need for dialysis. Revisions were performed 0.22 and 0.11 per 100 catheters days in the hemodialysis and infusion groups, respectively. Our total infection rate was 0.10 episodes per 100 catheter days, and the rate of infections necessitating catheter removal was 0.05 episodes per 100 catheter days in the hemodialysis group, which is lower than that reported in other big series. However, in the infusion group, the rate of infections necessitating catheter removal was 0.28 episodes per 100 catheter days.
Conclusion: Long-term central venous accesses using tunneled internal jugular catheters appeared to be safe and effective for both hemodialysis and long-term infusion therapies, with relatively higher infection rates in oncologic patients. 相似文献

This study was designed to compare the incidence of mechanical, thrombotic and infective complications in transjugular (IJV) and axillosubclavian (SCV) central venous catheters (CVC) in patients with hematological malignancy. In a prospective observational trial, 131 consecutive patients were classified into two groups: Group A included those with IJV catheter insertions under sonography guidance (n=61) and group B included those with SCV insertions under venography guidance (n=70). After catheter placement, patients were prospectively acquired and recorded to obtain the following data: success rates, total catheter days, and complication episodes per 100 catheter days. All procedures were technically successful. Total catheter days were 7800 (group A) versus 8391(group B). Mechanical complications were observed in three cases from group A and 11 from group B, with an incidence rate of 0.04 per 100 catheter days versus 0.13 (P=0.043), respectively. Two symptomatic thrombotic complications were observed in group B. The number of infective complications was not significantly different between the two groups (P=0.312). There was no difference in infective complication incidence between the two groups. To minimize catheter-related mechanical and thrombotic complications, however, the IJV approach is superior to the SCV approach. 相似文献

Objective
To assess the technical success and complication rates of the radiologic placement of central venous ports via the internal jugular vein.Materials and Methods
We retrospectively reviewed 1254 central venous ports implanted at our institution between August 2002 and October 2009. All procedures were guided by using ultrasound and fluoroscopy. Catheter maintenance days, technical success rates, peri-procedural, as well as early and late complication rates were evaluated based on the interventional radiologic reports and patient medical records.Results
A total of 433386 catheter maintenance days (mean, 350 days; range 0-1165 days) were recorded. The technical success rate was 99.9% and a total of 61 complications occurred (5%), resulting in a post-procedural complication rate of 0.129 of 1000 catheter days. Among them, peri-procedural complications within 24 hours occurred in five patients (0.4%). There were 56 post-procedural complications including 24 (1.9%, 0.055 of 1000 catheter days) early and 32 (2.6%, 0.074 of 1000 catheter days) late complications including, infection (0.6%, 0.018 of 10000 catheter days), thrombotic malfunction (1.4%, 0.040 of 1000 catheter days), nonthrombotic malfunction (0.9%, 0.025 of 1000 catheter days), venous thrombosis (0.5%, 0.014 of 1000 catheter days), as well as wound problems (1.1%, 0.032 of 1000 catheter days). Thirty six CVPs (3%) were removed due to complications. Bloodstream infections and venous thrombosis were the two main adverse events prolonging hospitalization (mean 13 days and 5 days, respectively).Conclusion
Radiologic placement of a central venous port via the internal jugular vein is safe and efficient as evidenced by its high technical success rate and a very low complication rate. 相似文献5.

The aim of this study was to evaluate the technical aspects and efficacy of placing tunneled central venous access catheters
(CVA) in the inferior vena cava (IVC) via a direct translumbar approach. Between August 1994 and July 1998, 50 CVA (Hickman
13.5 F) were placed in the IVC via a direct translumbar approach in 46 patients (10 males, 36 females) with a mean age of
39.9 years (age range 10–87 years). The indications were chemotherapy administration plus leukoaphoresis (n = 39), bone marrow transplantation (n = 2) and hemodialysis (n = 5). The reasons for placing the CVA in the IVC were cosmetic (n = 34), supradiaphragmatic venous thrombosis (n = 8), previous catheter infection (n = 2), and non-functioning arteriovenous fistula (n = 2). There were no immediate complications. The mean period of time the CVA was in place was 3 months (15 days to 15 months),
during which the function was excellent. The commonest late complication was infection (4 local, 6 bacteremia). Others included:
pain (n = 2), ureteric fistula (n = 1), pericatheter fibrin sheath formation (n = 6) and catheter-tip impaction (n = 2). Two catheters were damaged due to postprocedural inappropriate manipulations and two others fell off due to incorrect
fixation. Due to these complications, it was necessary to remove ten catheters, replace an additional four and reposition
two. Direct translumbar catheterization of the IVC is a safe and effective way of placing a long-term CVA with a moderate
complication rate.

Central venous access: techniques and indications in oncology 总被引:1,自引:0,他引:1

Long lines can be inserted centrally or peripherally through patent veins into the central venous system down to the atrial caval junction. Traditionally surgeons, anesthetists, cardiologists and more recently interventional radiologists have been placing them using vein cutdown or percutaneous needle puncture techniques. Typical candidates for implanted venous catheters are cancer patients undergoing long-term chemotherapy. The most important issues, in addition to the patency of central veins and the history of previous indwelling catheters, pacewires or venous thrombosis, are the patient's performance status, body mass index, medical history and respiratory status, and the relevant technique. The present article will give an overview of the radiological and surgical implantation techniques and will highlight the impact of imaging means on the technical feasibility, assessment and treatment of device-related complications. 相似文献

Purpose:
To review image-guided chest port insertion using the right internal jugular vein as the access site of choice. Material and Methods:
One hundred and eighteen subcutaneous chest ports were placed via the internal jugular vein in 117 patients with malignancies using both fluoroscopic and US guidance in interventional radiology suites. Results:
The technical success rate was 100% with no procedural complications. Follow-up was obtained in all patients with total access days of 40,450 days (mean, 342.8 days). Premature catheter removal was required in 8 patients (6.8%, 0.20 per 1,000 access days) due to non-treatable complications: 2 catheter occlusions/malfunctions (1.7%, 0.05 per 1,000 access days), 1 catheter-related skin erosion (0.85%, 0.024 per 1,000 access days), and 5 infections (4.2%, 0.15 per 1,000 access days). Two symptomatic right upper extremity venous thromboses also occurred (1.7%, 0.05 per 1,000 access days) that were treated successfully with anticoagulation. Conclusion:
Image-guided placement of internal jugular vein chest ports has a high success rate and low complication rate compared with reported series of unguided subclavian vein port insertion. The internal jugular vein should be used as the preferred venous access site compared to the subclavian vein. 相似文献

Purpose
To evaluate the efficacy and outcome of a flow confirmation study (FCS) in oncologic outpatients undergoing chemotherapy suspected of a central venous port (CVP) system-related mechanical complication.Materials and methods
A total of 66 patients (27 men, 39 women; mean age, 60 years) received FCS for the following reasons: prolonged infusion time during chemotherapy (n = 32), inability to inject saline fluid (n = 15), lateral neck and/or back pain (n = 6), subcutaneous extravasation of anticancer drug (n = 5), arm swelling (n = 4), and inability to puncture the port (n = 4). FCS consisted of examining the position of CVP, potential secondary shifts or fractures, and integrity of the system using contrast material through the port.Results
Of the 66 patients, 43 had an abnormal finding uncovered by FCS. The most frequent abnormal findings was catheter kinking (n = 22). Explantation and reimplantation of the CVP system was required in 21 of the 66 patients. Remaining 45 patients were able continue using the CVP system after the FCS without any system malfunction.Conclusion
FCS was effective for evaluating CVP system-related mechanical complications and was useful for deciding whether CVP system explantation and reimplantation was required. 相似文献13.
An unusual case of hemopericardium and presumed fatal cardiac tamponade complicating attempted right internal jugular vein
catheterization by the posterior approach is reported. Reports of complications in a series of internal jugular vein catheterizations
using various approaches (posterior, central, anterior, supraclavicular) and subclavian vein catheterizations are reviewed.
Internal jugular vein catheterization is not necessarily safer than subclavian vein catheterization: numerous factors determine
success rate and complication rate in central venous catheterizations. 相似文献

The purpose of this study was to compare the technical success and complication rates of ultrasonography-guided central venous
catheterization between adult and pediatric patients which have not been reported previously. In a 4-year period, 859 ultrasonography-guided
central vein catheterizations in 688 adult patients and 247 catheterizations in 156 pediatric patients were retrospectively
evaluated. Mean age was 56.3 years (range, 18 to 95 years) for adults and 3.3 years (range, 0.1 to 16.3 years) for children.
The preferred catheterization site was internal jugular vein in 97% of adults and 85% of children. The technical success rate,
mean number of punctures, and rate of single wall puncture were 99.4%, 1.04 (range, 1–3), and 83% for adults and 90.3%, 1.25
(range, 1–5), and 49% for children, respectively. All the differences were statistically significant (p < 0.05). Complication rates were 2.3% and 2.4% for adults and children, respectively (p > 0.05). Major complications such as pneumothorax and hemothorax were not seen in any group. In conclusion, ultrasonography-guided
central venous catheterization has a high technical success rate, lower puncture attempt rate, and higher single wall puncture
rate in adults compared to children. Complication rates are comparable in the two groups. 相似文献
