Obturator bypass using a ringed polytetrafluoroethylene graft for inguinal graft infection.

Inguinal vascular graft infections are high-risk events that cannot be controlled medically but require surgical intervention. This study reviewed the long-term clinical outcomes of obturator bypass using a ringed polytetrafluoroethylene graft for inguinal graft infection. A total of eight consecutive patients who underwent obturator bypass using a ringed polytetrafluoroethylene graft for inguinal prosthetic graft infection at a single medical center between January 2006 and October 2017 were retrospectively analyzed. The demographics, clinical characteristics, surgical procedure, and clinical outcomes were evaluated. There was no perioperative death; however, there were three operative complications. On the 1st and 9th postoperative day, two patients underwent hematoma evacuation in the pelvic cavity, and the other patient underwent suture reinforcement for partial dehiscence of the distal anastomosis on the 49th postoperative day. The median length of hospital stay was 14.5 (range, 7-29) days. Only one graft occlusion was observed at postoperative month 40; however, there were no ischemic symptoms. There were no limb amputations and postoperative deaths during the long-term follow-up period. There were no infections of the previous residual and obturator bypass grafts and inguinal infection during the follow-up period of 49 (range, 7-154) months. Obturator bypass for inguinal graft infection is feasible and durable with excellent long-term outcomes. However, perioperative bleeding should be taken into consideration.
