目的 观察子宫肌瘤动脉内数字减影血管造影 (IADSA)影像学特点。方法 对 15 6例子宫肌瘤患者行子宫动脉栓塞术 (UAE) ,通过术时DSA造影及术后DSA片观察子宫肌瘤DSA影像学特点。结果 15 6例子宫肌瘤的血供均来自子宫动脉 ,共分 3种类型 :①Ⅰ型 :一侧子宫动脉供血为主型 ,占 5 3 2 % (83/ 15 6 ) ;②Ⅱ型 :双侧子宫动脉供血为主型 ,占 34 6 % (5 4/ 15 6 ) ;③Ⅲ型 :单纯一侧子宫动脉供血型 ,占 12 2 % (19/ 15 6 )。子宫肌瘤的血管网分两层 ,一层存在于子宫肌瘤的表面形成粗大的血管网 ,另一层在子宫肌瘤的内部形成致密的毛细血管网。结论 子宫肌瘤属富血管性肿瘤 ,其血供来源于子宫动脉 ,由内外两层血管网组成
Objective To observe the imaging features of intramyocardial digital subtraction angiography (IADSA) in uterine fibroids. Methods 15 cases of uterine fibroids underwent uterine artery embolization (UAE), DSA angiography and postoperative DSA films observed uterine fibroids DSA imaging features. Results 15 cases of uterine fibroids blood supply from the uterine artery, is divided into three types: ① type: one side of the uterine artery blood supply-based, accounting for 53.2% (83/156); ② type: bilateral Uterine artery blood supply was the main type, accounting for 34.6% (54/156); ③Ⅲ type: uterine arterial blood supply alone, accounting for 12 2% (19/156). Uterine fibroids vascular network divided into two layers, one layer exists in the surface of the uterine fibroids to form a thick vascular network, and the other in the formation of dense uterine fibroids capillary network. Conclusion Uterine fibroids are vascular tumors, the blood supply from the uterine artery, vascular network composed of two layers inside and outside
