Bleeding caused by ectopic varices is an uncommon but important and life-threatening complication of portal hypertension. Spontaneous external hemorrhage from a recanalized umbilical varix is an extremely rare source of ectopic variceal bleeding. We report on the acute presentation of a patient with a bleeding umbilical varix and successful treatment with percutaneous umbilical vein embolization with sclerotherapy. This previously unreported technique is described, which adds a new therapeutic option for the management of this challenging clinical dilemma. A discussion on the recognition and management of ectopic varices is also provided.
异位静脉曲张引起的出血是门静脉高压症的一种不常见但重要且危及生命的并发症。再通的脐静脉静脉曲张自发性外出血是异位静脉曲张出血的极罕见来源。我们报告了一例脐静脉曲张出血的患者，采用经皮脐静脉栓塞联合硬化治疗取得了成功。描述了这种以前未报道的技术，为这种具有挑战性的临床难题的治疗增加了新的选择。还讨论了异位静脉曲张的识别和处理。
