[摘要] 目的 探讨东芝 320排动态容积CT(dynamic volume CT,DVCT)血管成像技术与超声对动脉性阴茎勃起功能障碍的应用价值。 方法 门诊性听觉视觉刺激试验(auditory visual stimulation test,AVSS)、阴茎海绵体血管活性物质注射(intracavernous injection,ICI)后疑诊为血管性勃起功能障碍患者38例,阴茎海绵体局部注射罂粟碱30 mg诱发勃起后在320-DVCT下进行检查。 结果 320-DVCT可以清楚显示阴茎海绵体动脉、阴茎背动脉、阴部内动脉。42例患者中,阳性33例(阴茎海绵体动脉16例、阴茎背动脉7例、阴茎内动脉10例),阴性9例。 结论 320 CT 阴茎动脉造影是诊断动脉性勃起功能障碍的可靠方法,应用多种后处理技术、四维立体成像能准确显示病变的部位。

[Abstract] Objective To explore the application value of Toshiba 320 row dynamic volume CT(dynamic volume CT, DVCT) angiography and ultrasound on arterial penile erectile dysfunction. Methods A total of 38 patients with suspected vascular erectile dysfunction after auditory visual stimulation test(AVSS), intracavernous injection(ICI) of vasoactive substances were examined under 320-DVCT after local injection of papaverine 30 mg to induce erection in penile corpus cavernosum. Results 320-DVCT could clearly show the penile cavernous artery, penile dorsal artery, internal pudendal artery. Of the 42 patients, 33 cases were positive(16 cases of penile cavernous artery, 7 cases of penile dorsal artery and 10 cases of internal pudendal artery), and 9 cases were negative. Conclusion 320 CT penile angiography is a reliable method to diagnose arterial erectile dysfunction, and using a variety of post-processing techniques, four-dimensional imaging can accurately show the site of the lesion.

阴茎勃起功能障碍(erectile dysfunction,ED)發病率与年龄呈正相关,是指阴茎持续性出现不能保持和(或)达到充分勃起以致不能获得满意的性活动。临床上目前常选用5型磷酸二酯酶抑制剂如万艾可等为代表对ED进行治疗,但部分ED患者对此类药物治疗不敏感。ED作为临床中一种极为常见的男科疾病,其在40~70岁男性中的发病率达52%,严重影响着男性的身心健康,该疾病的就诊率较低,为10%左右,因此对ED病因机制探讨、治疗方案研究显得尤为重要[1,2]。国外学者Lue TF等[3]在1985年最先提出采用高频超声及多普勒技术对患者的阴茎血管性勃起功能障碍进行评估。目前临床中将彩色多普勒超声作为诊断ED血流动力学异常的金标准[4]。随着CT技术的迅猛发展,320-DVCT能清楚显示心脏冠状动脉、脑血管、脊髓动脉等细小血管,有高速、低辐射、高清晰度、动态多参数成像及多种后处理技术,使发现动脉性ED患者的微小病变成为一种可能。……
