Objective: To report our experience with long term external catheters and implantable ports in the last 8 years.
Material And Methods: From December 1987 to August 1995 a total of 617 central venous catheters were implanted in 541 patients in our Interventionist Vascular Radiology Unit, 265 men (49%) and 276 women (51%), with a mean age of 46 years. A total of 335 (54%) were partially implantable external catheters and 241 (39%) implantable ports in chest and 41 (7%) in the forearm.
Results: A technical success--defined as the possibility of implanting the catheter--was achieved in 98% of cases. Immediate complications included 5 pneumothorax (0.8%), 11 accidental carotid artery puncture (2%) with no clinical relevance, 18 catheter misplacement (3%), and 8 vein spasm (1%). Fifty-two catheters (8%) were removed on account of infectious complications. Currently, 71 catheters are still in use (12%), 433 (70%) have been removed or the catheter was patent until patients's death.
Conclusions: Partially implantable central venous catheters and totally implantable ports are a safe alternative in patients requiring a central venous access for prolonged treatments. The low number of immediate complications renders the Interventionist Vascular Radiology Unit the proper place where to perform these procedures.

This is a prospective observational study designed to develop an echocardiography-guided tip location program for central venous catheter (CVC) implantation, and to assess the feasibility and the accuracy of the program. First, a multidisciplinary expert committee designed an echocardiography-guided tip location program; then, a pilot prospective observational study was conducted to assess the feasibility of the program in a vascular access clinic in a tertiary hospital. A total of 186 patients participated in the study.

Totally implantable subcutaneous venous access ports (TISVAPs) are essential for long-term central venous chemotherapy, delivering medication directly into the central veins of patients. While they play a critical role in reducing patient discomfort, TISVAPs pose a notable risk of post-insertion infections-particularly concerning for oncology patients with compromised immune systems due to aggressive treatment regimens. Our research addresses this issue by developing a predictive nomogram to estimate the risk of TISVAP-associated infections.

Introduction: The lack of peritoneal dialysis (PD) catheters designed explicitly for neonates creates significant challenges in the provision of neonatal PD. High resource settings can circumvent this limitation by resorting to alternative extracorporeal dialysis methods. However, in low-resource settings, PD remains the preferred dialysis modality, and the use of off-label catheters for PD results in complications such as omental wrapping and occlusion.

Although the implantation of the totally implantable venous access ports globally is increasingly sophisticated, there is still a dearth of absolute standardization in the technical choice of each surgical step, with numerous technologies demonstrating significant applicability. This review comprehensively summarizes the diverse choices of implantation procedural techniques related to the pocket location, vein access, port specification, catheterization method, puncture guidance, single-incision technique, catheter tip positioning method, port fixation, skin closure, and first-use period. The aim is to provide surgeons with alternative options when they encounter different problems in each procedure due to the diverse clinical characteristics of patients during venous port implantation.
