在台灣40 歲以上男性有百分之26 有勃起功能障礙，治療大多使用磷酸雙脂酶-5 抑制劑(Phosphodiesterase-5 inhibitors)，但是對於血管狹窄所造成勃起功能障礙(Arteriogenic Erectile Dysfunction)的患者卻是成效不佳，近年 來周邊血管的導管治療(Percutaneous Transluminal Angioplasty, PTA)技術已日漸成熟，我們利用電腦斷層血管攝影 術(Computed Tomography Angiography, CTA)診斷配合血管攝影術及治療周邊血管的擴張氣球，治療動脈狹窄所造 成的勃起功能障礙。透過這樣的技術來治療以往用藥效果不佳，且歸為內會陰動脈(Internal Pudendal Artery, IPA) 血流供應不足所造成勃起功能障礙。但是治療目標血管非常細小，手術醫師與放射師的合作默契更是一大考驗， 手術時間也較為冗長，且治療所使用耗材都不是健保給付項目，對患者來說是一筆可觀治療費用，但卻是對於血 管因素造成的勃起功能障礙(Erectile Dysfunction, ED)卻是最好的治療方式，本案例在治療過後，經過五項國際勃 起功能指標量表(IIEF-5)評估後，滿意度提升達到一個等級。

In Taiwan, 26% of men over 40 years old have erectile dysfunction, Most of them treated by Phosphodiesterase-5 inhibitors. However, the patients with vascular stenosis caused erectile dysfunction have insufficient benefited from it. In recent years, the treatment of peripheral vascular catheter technology has become more mature. We use CT angiography and conventional angiography to diagnose vascular disease causing erectile dysfunction, followed by revasculization interventions including peripheral vascular surgery and balloon angioplasty for treatment. By means of these procedures, we can treat vascular erectile dysfunction patients who had poor response to medical treatment. Due to the target vessels are very small, it is a great challenge for the technical cooperation between operator and radiologist. The operation time is relatively long. The use of instrument and the procedure are not universal health insurance payments project, being is a substantial cost of treatment to patient After our treatment, using five international index of erectile function scale (IIEF-5) assessment. There was a significant improvement in distress.
