Transcatheter venous embolization with metallic coils is a safe and reliable method for the treatment of pelvic congestion syndrome and pelvic varicocele. While rare, coil migration to the pulmonary arteries is potentially fatal. We report the migration to the pulmonary artery of a cluster of nine metallic microcoils placed in the internal iliac vein to obliterate giant rectal varices. Our patient suffered no severe sequelae. To avoid coil migration to the pulmonary arteries, the coils chosen for placement must take into consideration the characteristics of the target vessels, particularly of larger veins.
经导管用金属线圈进行静脉栓塞是治疗盆腔淤血综合征和盆腔静脉曲张的一种安全可靠的方法。虽然罕见,但线圈迁移至肺动脉可能会致命。我们报告了为消除巨大直肠静脉曲张而置于髂内静脉的一簇九个金属微线圈迁移至肺动脉的情况。我们的患者未出现严重后遗症。为避免线圈迁移至肺动脉,放置时所选用的线圈必须考虑靶血管的特征,尤其是较大静脉的特征。
