| 目的 探讨动态增强MRA(DCE-MRA)在经颈静脉肝内门体分流术(TIPS)术前定位中的作用。 方法 收集46例肝硬化门脉高压患者的MRA图像,测量并根据测量结果进行穿刺。 结果 肝静脉穿刺点到门静脉穿刺点平面上下垂直距离(AA’)为(22.63±10.21)mm;肝静脉穿刺点到门静脉穿刺点平面前后垂直距离(A’A’’)为(13.93±1.07)mm;前后穿刺角度为(31.64±9.23)°;肝静脉、门静脉穿刺点距椎体右缘距离分别为(23.51±2.12)mm、(38.51±5.36)mm;左右穿刺角度为向右偏(33.57±8.93)°。45例穿刺成功,且穿刺次数较少。 结论 门静脉穿刺点位置变化较大,定位需个体化。DCE-MRA是一种有价值且无损伤的定位方法,对TIPS术前定位有重要意义。 |

| Objective To explore the role in the localization of vascular puncture points with dynamic contrast-enhanced magnetic resonance angiography (DCE-MRA) before transjugular intrahepatic portosystemic shunt (TIPS). Methods MRA images of 46 patients with portal hypertension were measured. The patients were then punctured according to the measurement Results The supero-inferior distant from the puncture point of hepatic vein to plane of right branch of portal vein (AA’) was (22.63±10.21)mm, the anteroposterior distant from the puncture point of hepatic vein to plane of right branch of portal (A’A’’) was (13.93±1.07)mm, the angle of sag was (31.64±9.23)°. The distant from puncture point of hepatic vein (AS) and right branch (BS) were (23.51±2.12)mm and (38.51±5.36)mm. The angle of cor was (33.57±8.93)°. Forty-five patients were successful punctured, and the time of puncture decreased. Conclusion The location of portal vein puncture point during TIPS are changeable, therefore individualized location of positioning is needed. DCE-MRA is a valuable non-invasive method of localization, playing an important role in localization of vascular puncture points of TIPS. |
