中文摘要 | 對子宮肌瘤與腺瘤的經動脈栓塞,擁有很高的成功率。在國外已是手術外的另一種替代性治療。了解子宮動脈的解剖特性,對子宮肌瘤與腺瘤的經動脈栓塞,有很大的幫忙。 我們收集共有RR 個病人,由兩側股動脈同時進入檢查。採三種不同的角度攝影。正面直像,同側PS 度斜像,對側PS 度斜像,用w 型管以同時攝影。利用子宮動脈的s 型特性,以認定子宮動脈開口,分析子宮動脈管腔大小。將導管置放在子宮動脈橫向部,以永久性顆粒栓塞劑,將子宮動脈塞滿。此研究結果發現,對側PS度斜像,最易於認定子宮動脈開口;對於大多數的子宮動脈栓塞,RLP>dë 的導管,常可勝任。 |
英文摘要 | To analyze uterine arteriographic features of patients with uterine myomas and adenomyosis that might facilitate transcatheter uterine artery embolization (UAE). Seventy-eight uterine arteriograms of 44 consecutive patients (mean age 38.8 year-old ± 6.8) (32 with uterine myoma, mean age of 38.6 ± 6.7 and 12 with uterine adenomyosis, mean age of 39.2 ± 7.1) treated with transcatheter uterine artery embolization were retrospectively reviewed by 2 radiologists in consensus. Ten uterine arteriograms were excluded because of poor diagnostic quality or incomplete visualization of uterine artery origins. The indication for UAE was symptomatic patients who refused or were not suitable for traditional surgery. UAE was performed via bilateral common femoral approach using two angiographic catheters. Simultaneous angiographic studies of both internal iliac arteries in AP, bilateral 25-degree oblique projections and selective uterine artery studies only in AP projections were obtained by injecting contrast medium into two angiographic catheters linked by a “Y” luer-lock connector. The arteriographic features thought relevant to UAE were the incidence of a typical “U” course, the radiographic projection that best demonstrated the origin of uterine arteries from internal iliac artery, and the average size of the uterine artery measured at the descending segment. Our analysis showed that the origin of uterine artery was best visualized in contralateral 25-degree oblique projection in 67% (52 of 78) arteriograms, ipsilateral anterior oblique in 17 % (13 of 78) and straight A-P in 17%. The classic “U” configuration occurred in 100% of uterine arteries. The average size of the uterine artery at the descending segment measured 2.9 mm for uterine myomas and 2.4 mm for uterine adenomyosis. Selective catheterization of the uterine artery was successful in 87% of cases using a 4.2-French Shepard hook angiographic catheter (equivalent to 1.4 mm in outer diameter). Transient uterine artery spasm occurred in 13% of uterine arteries (10 of 78) with all but one could be relieved by intra-arterial injection of 25 µg of nitroglycerin. Microcatheter was used in 17% (6 of 44) of patients, but all during our early experience. Uterine artery embolization was technically successful in 100% of our patients and no miscannulation of arteries other than the uterine arteries was noted. Our study revealed that a proper knowledge on the typical uterine arteriographic features facilitated proper and safe performance of transcatheter uterine artery embolization. |
