Abstract:

Vascular crisis is a thorny problem which may be encountered during the process of vascularized free flap transplantation. Improper handling can lead to serious consequence, such as flap transplantation failure. The occurrence of intraoperative vascular crisis can significantly prolong surgical time, aggravate the patient′s physical function consumption, exacerbate the operator′s fatigue, and lower surgical efficiency. Dealing with postoperative vascular crisis usually requires surgical exploration, which is an important burden for both the patient and the surgeon. Once it is not detected in time or mishandled, it may lead to flap transplantation failure. Therefore, the prevention, timely detection, and effective management of vascular crisis in clinical practice can reduce the physical, mental, and economic burden on patients to some extent. This article aimed to review the research progress on vascular crisis in vascularized free tissue flaps.

Key words: Free tissue flap, Vascular crisis, Vascular anastomosis, Oral maxillofacial defects, Reconstructive surgery, Microsurgery
