Either radionuclide or contrast venography, or both, were performed in nine patients 2 months to 4 years after insertion of Mobin-Uddin caval umbrella filter for prevention of recurrent pulmonary embolism. In six patients the cava was occluded, and three major groups of collaterals were observed (central, intermediate and superficial). Large gonadal veins, which may predispose to recurrent embolism, were seen in two cases. Radionuclide venography gave a clear indication of caval patency or occlusion, and distinguished central from superficial collaterals. Identification of specific gonadal veins required contrast femoral or iliac venography.
在植入莫宾-乌丁下腔静脉伞形滤器以预防复发性肺栓塞后的2个月至4年,对9例患者进行了放射性核素静脉造影、造影剂静脉造影或两者同时进行。6例患者的下腔静脉闭塞,观察到三大组侧支循环(中央组、中间组和浅表组)。在2例患者中发现了可能易导致复发性栓塞的大生殖静脉。放射性核素静脉造影清楚地显示了下腔静脉的通畅或闭塞情况,并区分了中央侧支和浅表侧支。识别特定的生殖静脉需要进行股静脉或髂静脉造影。
