Double Arterialized Free Jejunal Flap

ABSTRACT

In a standard free jejunal transfer, one artery and one vein are anastomosed. However, when raising the jejunal flap, a one-segment jejunum sometimes has two arteries and one accompanying vein as a vascular pedicle. Free jejunal transfer in which two arteries and one vein are anastomosed was designed. We report on the safety and advantages of using this artery-dominant transfer when performing microvascular anastomosis. This technique was used when a one-segment jejunum had two arteries and an accompanying vein. Eight patients underwent this arterial-supercharged free jejunal transfer. All flaps survived, and no complications developed except for two cases of intraoperative thrombosis before the procedure. It is important to transfer the artery-rich graft into the same physiological environment by reconstructing the similar hemodynamics. The grafts can be transferred without harm. This artery-dominant method can be an option when conditions are unfavorable for safer jejunal transfer.
