A new injection portal for brachially inserted central venous catheter. A multicenter study

Area of Science:

• Vascular Surgery
• Medical Devices
• Oncology Support

Background:

• Totally implantable portal systems are essential for long-term central venous access in various patient populations.
• Standard venous portal systems may not be suitable for all patients, necessitating alternative solutions.
• The P.A.S. Port system represents a novel approach utilizing brachial veins for venous access.

Purpose of the Study:

• To evaluate the safety, efficacy, and patient acceptance of the P.A.S. Port system.
• To assess the complication rates and success of implantation in a multicenter setting.
• To determine the suitability of the P.A.S. Port system as an alternative for patients needing central venous access.

Main Methods:

• A prospective study involving 61 P.A.S. Port system implantations across five centers.
• Patients included those with malignant (52) and non-malignant (9) diseases.
• Implantation involved subcutaneous placement in the forearm with percutaneous or cutdown catheterization via basilic or cephalic veins under local anesthesia; catheter tip position confirmed by imaging.

Main Results:

• A total follow-up of 323 months was achieved.
• Forty-five systems remained functional at the end of the observation period.
• Complications included temporary armphlebitis (5 patients), infection (2 explants), skin rupture (1 explant), and suspected leakage (1 explant).

Conclusions:

• The P.A.S. Port system is characterized by ease and safety of implantation, achieving a high success rate and low complication rate.
• The system is well-accepted by both patients and healthcare professionals.
• It provides a valuable alternative for patients who are unsuitable for standard venous portal systems, offering excellent venous access.
