前列腺供血动脉的来源及临床意义

Clinical evaluation of the prostatic arterial origination

目的观察DSA下前列腺供血动脉的来源,为动脉栓塞治疗前列腺增生提供参考。方法对72例选择性及超选择性插管成功病例,进行前列腺供血动脉造影,观察并记录前列腺供血动脉的来源、个数、优势供血动脉。结果前列腺供血动脉复杂(72例,共237支供血动脉),常有数支动脉同时参与供血,主要的起源动脉和个数为:膀胱下动脉69支、髂内动脉63支、阴部内动脉52支、直肠下动脉29支、膀胱上动脉14支。优势供血动脉63支,主要来源为:髂内动脉3支、膀胱下动脉20支、阴部内动脉6支和直肠下动脉2支。结论动脉造影检查可对前列腺供血动脉的来源和优势供血动脉作出正确判断,对指导介入栓塞治疗具有重要的临床意义。

Objective To investigate the origin of prostatic blood-supply by digital subtraction angiography （DSA） and provide references for the arterial embolization of prostatic hyperplasia. Methods A total of 72 male patients with successful selective and super-selective prostatic arterial catheterization angiographies were observed and recorded the original arterial blood-supply of the prostate, number of the prostatic arteries and the predominant blood supply. Results The blood-supply of prostate is very complicated including the original prostatic arterial supply from the inferior vesicle arteries （69）; the internal iliac arteries （63）; the internal pudendal arteries （52）; the inferior rectum arteries （29）; the superior vesicle arteries （14）. The predominant arterial supply include the internal iliac arteries （37）; the inferior vesicle arteries （20） ; the internal pudendal arteries （6） and the inferior rectum arteries （2）. Conclusion Arterial contrast medium angiography can correctly demonstrate and assess the original arterial supply of prostate, providing significant guidance for further interventional embolization.
