[Experimental evaluation of vascular two-sided velour prostheses]

Area of Science:

• Biomaterials Science
• Vascular Surgery
• Surgical Innovation

Background:

• Vascular grafts are crucial for reconstructive surgery.
• Development of novel graft materials is ongoing.
• Knitted grafts offer specific structural advantages.

Purpose of the Study:

• To evaluate the performance of novel Polish knitted vascular grafts.
• To assess the suitability of velour-surfaced grafts for abdominal aorta implantation.
• To determine the healing and integration characteristics of these grafts.

Main Methods:

• Implantation of knitted vascular grafts with dual velour surfaces into the abdominal aorta of six dogs.
• Evaluation of surgical handling, including suturing ease and initial fluid permeation.
• Post-implantation assessment of graft healing and intimal lining formation.

Main Results:

• Suturing of the grafts was straightforward.
• Initial fluid permeation through the grafts was minimal and ceased within 2.5 minutes.
• Grafts demonstrated successful healing and were uniformly covered by an intimal layer.

Conclusions:

• Polish knitted vascular grafts with velour on both sides exhibit favorable surgical handling and early healing characteristics.
• These grafts show potential for successful application in reconstructive vascular surgery.
• The observed minimal permeation and good integration suggest a promising biomaterial for aortic repair.
