中文摘要 | 女性骨盤腔脫垂可能涉及單一或多重器官的狀況,為了獲得手術前的確定診斷,動態磁振造影可能可以取代傳統 X 光透視攝影或超音波檢查,收集更足夠的資訊,允許外科醫生有一個有效的術前計劃。不管有沒有尿失禁的症狀, 在手術之前,九名患有骨盤腔脫垂的婦女接受動態磁振造影檢查。這些患者全部採取仰臥的位置檢查。當患者的骨盤腔是在放鬆和繃緊期間,每相隔 4 秒,我們以超高速的掃描取得骨盤腔中央的矢狀合縫圖像。然後,再把各種動態磁振造影圖像,以特定的測量方法加以分析,呈現骨盤腔脫垂的多樣性和程度差異狀況。PCL 線、H 線、M 線和 levator plate 角度被分別記錄下來。根據這些測量數據,五名受檢者 (5/9) 被證實為多重器官的骨盤腔脫垂患者,四名受檢者 (4/9) 只是單一器官的骨盤腔脫垂患者。七名患者接受手術治療,手術後,所有患者的症狀都獲得重大改善。其中二名患者幾乎完全治癒。動態磁振造影檢查明白展示在骨盤腔內器官下降的簡單或複雜狀況。不僅增加手術的成功率,而且協助外科生做好術前計劃,準確地預測手術的結果。這些結果讓手術醫師高度滿意,動態磁振造影也許能成為骨盤腔脫垂手術前的標準檢查。 |
英文摘要 | Prolapse of pelvic organs in a female can be simple or complex. To make a definite diagnosis of pelvic prolapse preoperatively, dynamic magnetic resonance (MR) is an alternative to conventional fluoroscopic or sonographic examination, with the advantage of providing greater details, and thus helping the surgeon to have a good preoperative plan. Nine women suffering from pelvic prolapse with or without urinary stress incontinence underwent dynamic MR imaging examination (1.0T Magnex100/HP, Shimadzu, Kyoto, Japan) before surgery. All patients were examined in the supine position. A single-shot ultra-high speed scan (FE/8/3.02-20°, 128, 100%-100% 1 NEX 1 slice 10 mm L1.0 second) was used to obtain midline sagittal images, with the patients at rest and during pelvic strain. MR images were then obtained every 4 seconds. Each examination was analyzed, based on specific measurements, to determine the presence and extent of prolapse of pelvic organs. The pubococcygeal, levator hiatus width and muscular pelvic floor relaxation lines, and the angle of the levator plate were identified. Based on these measurements, multicompartment involvement in the pelvic prolapse was confirmed in five patients (5/9). Four patients (4/9) had single compartment involvement. Seven patients underwent surgery. All patients reported significant improvement in their symptoms and signs after surgical intervention. Two patients had an almost complete recovery. MR demonstrated simple or complex organ descent in all pelvic compartments, and may become a standard preoperative examination for pelvic floor abnormalities. The MR images facilitated comprehensive planning by the surgeon; thus, they can increase the success rate and help to accurately predict the outcome of the surgical intervention. The surgeons also expressed high postsurgical satisfaction with the information provided by dynamic MR. |
