Abstract

The purpose of this study was to determine the effectiveness of venous occlusions achieved by embolization with platinum microwire coils. Follow-up venographies in 19 patients, 1-20 months (average 8 months) after coil embolizations, were evaluated. Twenty-eight of 126 (22.2%) coil embolizations were found to be patent. Coils which had not formed or partially formed upon embolization had a patency/recanalization rate of 37.5% (12/32). Among coils which had formed nearly completely or completely only 16 of 95 (17%) showed venous patency. As coil embolization had been augmented by sclerotherapy in all patients, the effectiveness of long-term venous occlusion by platinum wire coils alone is probably lower than our figures indicate. We conclude that attention to complete or near-complete coil formation upon embolization appears to be critical to maximize long-term occlusive effects of platinum microcoils. Their effectiveness in general, however, is lower than anticipated.

摘要

本研究的目的是确定用铂微丝线圈栓塞实现静脉闭塞的有效性。对19例患者在进行线圈栓塞后1至20个月（平均8个月）的随访静脉造影进行了评估。在126次线圈栓塞中，有28次（22.2%）被发现仍通畅。栓塞时未形成或部分形成的线圈的通畅/再通率为37.5%（12/32）。在几乎完全形成或完全形成的线圈中，95次中有16次（17%）显示静脉通畅。由于所有患者的线圈栓塞均通过硬化疗法增强，单独使用铂丝线圈实现长期静脉闭塞的有效性可能低于我们的数据所示。我们得出结论，栓塞时注意线圈的完全或接近完全形成似乎对于最大化铂微线圈的长期闭塞效果至关重要。然而，它们的总体有效性低于预期。
