Urinary obstruction secondary to benign prostatic hyperplasia is a late manifestation of the disease, and a poor prognostic sign for responding to conservative therapies. Prostatic artery embolization - when performed successfully - can be an effective treatment for reducing obstructive urinary symptoms. Outlined in this report is the successful recanalization of a prostatic artery chronic total occlusion prior to embolization in an 89-year-old man with benign prostatic hyperplasia, who initially presented with urinary obstruction. Prostatic artery recanalization was possible using a specialized crossing technique from peripheral arterial disease interventions, and allowed for more distal embolization of the prostate gland. This technique may be useful when advanced atherosclerotic disease limits the feasibility and clinical success of prostatic artery embolization.
良性前列腺增生继发的尿路梗阻是该疾病的晚期表现，也是对保守治疗反应不佳的预后不良迹象。前列腺动脉栓塞术——如果成功实施——可以成为减轻梗阻性尿路症状的有效治疗方法。本报告概述了一名89岁患有良性前列腺增生且最初表现为尿路梗阻的男性患者，在栓塞术前成功再通慢性完全闭塞的前列腺动脉的过程。使用外周动脉疾病干预的专门通过技术可以实现前列腺动脉再通，并允许对前列腺进行更远端的栓塞。当晚期动脉粥样硬化疾病限制了前列腺动脉栓塞术的可行性和临床成功率时，该技术可能会有用。
