Four types of venous flaps for wound coverage: a clinical appraisal.
Venous flaps were used for coverage of hand wounds over exposed bones, joints, and tendons in 28 patients. Four types of operations were performed. Among them type IV was the best. It included the advantages of perfusion in types I and III, but excluded their disadvantages. The viability of venous flaps was confirmed. Clinical observation showed that a venous flap is not merely a composite graft. The presence of a vascular network in the flap helps to ensure initial survival before the establishment of neovascularization between the venous flap and the recipient site. Partial loss of a flap was observed in two cases and complete failure was seen in one case. Viability versus flap size and modality of perfusion are analyzed. With total venous perfusion, small venous flaps usually survive better than large ones. For large venous flaps, arterialized venous perfusion is better than total venous perfusion. Venous flaps are useful for wound coverage of fingers and hand, but they do not replace cross-finger flaps or other conventional flaps when these simpler flaps are available.
