Internal Arteriovenous Fistula Within a Radial Forearm Flap – A Novel Technique to Increase Femorodistal Bypass Graft Flow to the Diabetic Foot and Flap Covering Ischaemic Tissue Loss

Abstract

In a group of diabetic patients increased flow in a vascular bypass graft was achieved by an internal av-fistula within a radial forearm flap. This method is useful in selected cases with poor run off and large ischaemic lesions.

Salvage of a free osteocutaneous fibula flap by creating a distal arteriovenous fistula in facial reconstruction

“…Studies have reported that an AV fistula of less than 1 cm in diameter steals less than 20% of the cardiac output and can be used safely. 9 In addition, venocutaneous fistulae can be performed to decrease high resistance in solely venous problems. 5 In the case presented here, the OCFF was modified to a bone flap by discarding the skin island due to vascular insufficiency.…”

Axially vascularised mandibular constructs: Is it time for a clinical trial?

“…13 fistula is less than 1 cm and the fistula accepts less than 20 percent of the cardiac output (Blaisdell et al, 1966;Tukiainen et al, 2006;Eweida et al, 2013;Horch et al, 2014). Regarding bone density and mineralization distal to an AV fistula, contradictory results are shown in the literature, ranging from an increase in bone growth (Vanderhoef et al, 1963) to decreased mineralization and augmented osteopenia (Muxi et al, 2009).…”

Ausgedehnte Gewebedefekte bei vaskulären Wunden - Möglichkeiten der plastischen Chirurgie

“…Für die Rekonstruktion von Hautweichteildefekten unter Einsatz von Gefäßbypassoperatio-nen haben sich jedoch Lappenplastiken mit einem geringen Flusswiderstand und großem Gefäßkaliber bewährt. Hierbei sind vor allem der Latissimus-dorsi-, der Rectus-abdominis-, sowie der Radialis-Lappen zu nennen [15,16,19,37,41,42] [50]. In der Zukunft kann unter Umständen eine zusätzliche Optimierung der Therapie durch den Einsatz von Stammzellen erreicht werden [51].…”
