Background: Traditional treatment of infected polytetrafluoroethylene (PTFE) grafts consist of removal of the entire prosthesis. Closure of the native vessels may compromise vascular patency. We examined the outcomes for patients in whom a PTFE remnant of an infected graft was retained on the vessel.
Methods: We reviewed the operating room log from 2000 to 2011 and identified all patients who had partial removal of an infected PTFE graft used for hemodialysis or peripheral bypass. These patients were examined for subsequent complications.
Results: Twenty-seven patients underwent 30 partial graft excisions with mean follow-up of 27 months. A total of 17% (5 of 30) of the partial graft resection procedures resulted in complications. Of 48 total remnants left behind at the arterial or venous anastomoses, reinfection occurred in 15%.
Conclusions: Leaving a well-incorporated small 1-to 5-mm PTFE remnant at the arterial or venous anastomoses can be performed safely with a low risk of complications.

This case series reports two cases of scleral lens (SL)-associated suture erosion of polytetrafluoroethylene CV-8 (Gore-Tex, Newark, DE) in scleral-sutured CZ70BD (Alcon, Fort Worth, TX) posterior chamber intraocular lens (SS-PCIOL). Suture erosion after SS-PCIOL has been reported in two of the patients who were fitted with SL for visual acuity improvement. Erosion was corrected in both cases with suture repositioning and corneal patch graft, with one patient requiring the exchange of the intraocular lens.

Left ventricular assist device (LVAD) explantation is technically challenging during heart transplantation (HT) and is associated with intraoperative and postoperative blood loss. This single institution study examined the effects of partial polytetrafluoroethylene (PTFE) protective coverage during HeartMate 3 implant on perioperative blood loss during the explant-HT. We found that partial PTFE coverage of the outflow graft and chassis during HeartMate 3 implant is significantly associated with reduced intraoperative and postoperative transfusion requirements, and postoperative chest tube output.

The increasing prevalence of cardiovascular diseases highlights the urgent demand for small-diameter artificial vascular grafts (SD-AVGs). However, the clinical application of current SD-AVGs is limited by complications such as thrombosis and proliferative stenosis. We first designed and fabricated a triple-layered SD-AVG (TL-SD-AVG) composed of polycarbonate polyurethane and polyethylene terephthalate using electrospinning and mixed weaving techniques.

Vascular surgical site infections (SSI) are common and associated with graft infection, surgical reintervention, and increased lengths of stay. While antibiotic prophylaxis and negative pressure dressings have improved SSI rates, reported incidence remains as high as 30%. Robotic approaches have decreased surgical site infections in multiple surgical specialties, but remain without a vascular surgery indication.

Background: Living donor liver transplantation (LDLT) is a crucial alternative to deceased donor transplantation, especially in regions with limited access to cadaveric organs. Right lobe graft implantation into the inferior vena cava (IVC) requires advanced surgical techniques to optimize outcomes and reduce complications.
Aim: To compare two venous anastomosis techniques-direct polytetrafluoroethylene (PTFE) grafting of V5-V8 veins to the IVC triangulation to the right hepatic vein (RHV)-in terms of graft viability and postoperative outcomes.
