脾动脉羊毛钢丝襻栓塞术治疗脾功能亢进

Partial splenic artery embolization using spring coils in the treatment of hypersplenism

自１９９０年９月至１９９６年７月，我们采用脾动脉羊毛钢丝襻栓塞治疗脾功能亢进３３例，３５例次（２例二次栓塞）。术前平均血小板计数（５２±１３）×１０９／Ｌ，术后２个月平均血小板计数（１１１±５５）×１０９／Ｌ。２７例有效（２２例显效，５例明显改善），有效改善率８１．７％，平均随访１０．２个月。作者对脾动脉羊毛钢丝襻栓塞后血流量变化，血小板破坏部位，钢丝襻栓塞位置与治疗效果的关系进行了讨论。结果表明：脾动脉羊毛钢丝襻栓塞术疗效好，并发症少，又保存了脾脏的免疫功能。

Fron September 1990 to July 1996, partial splenic artery embolization using spring coils was performed in 33 patients with hypersplenism. The embolization was carried out once in 31 patients and twice in the remaining 2. The average thrombocyte count was (52±13)×109/L preoperatively.The average thrombocyte count increased to(111±55)×109/L 2 months postembolization.The effective cases were 27 of 33 patients (81.7%).The thrombocyte count returned to nomal in 22 and improved in 5. The average followup period was 10.2 months. The relationship between the change of splenic artery bloodflow postembolization, the site of platelet destruction,location of spring coils and therapeutic effect was discussed. Our results show that partial splenic artery embolization using spring coils might yield better therapeutic effect with less complications
