Treatment of Venous Hemorrhage Between Vestibulocochlear Nerve and Hypertrophic Flocculus During Microvascular Decompression Procedure for Hemifacial Spasm.

Hemifacial spasm is a kind of painless, intermittent, involuntary, and irregular unilateral facial muscles convulsion. Microvascular decompression has become the standard surgical procedure for hemifacial spasm after years of popularization and development. In the article, the authors described in detail a therapeutic strategy for rapid intracranial venous bleeding between vestibulocochlear nerve and hypertrophic flocculus. When simple compression hemostasis failed, the authors applied fibrin glue and gelatin sponges for hemostasis and finally successfully controlled venous bleeding. The patient's symptoms were completely relieved after operation. Routine postoperative examination of head computed tomography revealed no intracranial hemorrhage. The combination of fibrin glue and gelatin sponges may be a possible solution for complicated and intractable venous hemorrhage during microvascular decompression procedure in some patients with hemifacial spasm.
