The position of ‘shunt restriction’ along an arterialized vein affects venous congestion and flap perfusion of an arterialized venous flap

Evolution of free flap reconstruction in the upper extremity: perspective from a tertiary plastic and reconstructive institution

“…Arterialized venous flaps are common for single webspace contractures but are plagued with increased complication rates. The advent of shunt-restriction optimized the peripheral perfusion through the venous flaps and has led to decreasing rates of congestion, making this a reliable, thin and versatile alternative (Lam et al., 2013; Lin et al., 2016; 2010).…”

The use of indocyanine green angiography in arterialized-venous free flaps: Case report and insight into flap vascular physiology

“… 1 Arterialized venous flaps (AVFs) present several advantages: great flexibility in design, minimal donor site morbidity, no major artery harvested, and an easy suprafascial dissection. 2 , 3 , 4 , 5 …”

“…AVFs have remained unpopular due to their tendency to develop venous congestion and flap necrosis. 1 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 Literature reports have proposed hypotheses with regards to survival mechanisms, yet their physiology remains unclear. 1 , 2 , 3 , 4 , 5 …”
