Brief summary

This study will assess the nitinol U-clip as an alternative to conventional microsurgical suture for arterial anastomoses in free tissue transfer.

Detailed description

Within Scott & White, a total of 25 free flaps will be performed using U-clips for microvascular anastomoses in lieu of traditional suturing techniques. Each of these free flaps may be in individual patients or two anastomoses may be included in one patient. Historical controls will be used for comparison of complication rates of U-clip versus sutured anastomoses. Postoperatively, the study participants will be evaluated at 2 weeks (+/- 1 week) and at 3 months (+/- 1 month) follow up.

Interventions

DEVICEnitinol u-clip

The U-clip is comprised of nitinol, an alloy of nickel and titanium.
