喀血に対する気管支動脈塞栓術 ―Stainless Steel Coilを用いて―

Four patients with hemoptysis were treated by bronchial artery embolization, using only stainless steel coils 5mm or 3mm in diameter as the embolic material. Immediate control of hemoptysis was achieved in 3 of the 4 patients without any significant complication. Two of these patients are alive without recurrent hemoptysis, one of them 3 months and the other two years one month after the embolization. One of these patient died of renal failure 5 days after embolization. Recurrent hemoptysis occurred in 1 of the 4 patients with incomplete embolization. A second attempt at embolization failed because the coil fell down through the aorta into the iliac artery. The coil was surgically removed under fluoroscopy. Since the stainless steel coil is a non-absorbable embolic material, if carefully used, longer therapeutic results can be achieved for patients with hemoptysis.
