Preoperative ultrasound mapping of the saphenous vein: prognostic value on early post operative results, a prospective study.
A prospective series of 92 patients had their greater saphenous vein assessed with duplex ultrasound scanning prior to planned infrainguinal bypass procedures. Sixteen (17%) bypass procedures thrombosed within the first week postoperatively. A naturally occurring optimal vein diameter was discovered: 3.5-4.2 mm at mid-thigh level and 0-1.5 mm less at mid-calf level. It was significantly correlated with higher one week patency: thrombosis occurred in 11% in veins with this optimal diameter combination and in 19% in all other combination (P < 0.05). These results confirm and expand a retrospective study.
