Abstract
右肝動脈(right hepatic artey，RHA)通常是固有肝動脈(proper hepatic artery，PHA)的二終末之一。所謂「異常的」( anomalous)或 「迷走的」(aberrant )或「替代」(replacing)放「副」(accessory)右肝動脈則源自上腸系膜動脈( Superior mesenteric artery，SMA)彼等之好發率不同，統計為3.3-18.5%。本研究 在242例 中共找到31例迷走右肝動脈，百分比為12.8，一般情況下，在上腸系 膜動 脈注射造影劑便足夠顯示此異常分支之右肝動脈，但在治療性栓 塞術時則要相當熟 練之技巧才能使導管插入此一動脈分枝。本文僅提 供本科同仁為了克服迷走右肝動 脈彎曲之管道而採用的三種方法：（ 1）樞軸技術（pivoting technique），（2） 圈式技術（loop technique）或modified Waltman氏技術，(3)偏轉器技術併用可操 縱 導管（deflector-technique with steerable catheter）。 The right hepatic artery (RHA) is generally one of the two main branches from the proper hepatic artery (PHA). However, the so-called "anomalous/aberrant/replacing / accessory" RHA which arises from the superior mesenteric artery (SMA) constitues a variable frequency from 3.3% to 18 .5% (7-9). In our series 12.8% were found. Demonstration of the aberrant RHA possesses no technical problem while performing diagnostic angiography, as injection of the contrast medium in the SMA trunk is sufficient. On the contrary, it would require much skill to overcome the alternative bondings while attempting therapeutic embolization. We present our experiences here on overcoming the ziggag passage of the RHA and differentiated into 3 different methods, namely: 1. Pivoting technique, 2. Loop technique or modified Waltman's technique which can be easily achieved with a simple C-Curved catheter, and 3. Deflector technique with steerable catheter.
