Internal maxillary artery ligation is effective in treating epistaxis. Occasionally a patient may continue to hemorrhage after this procedure. Evaluation of postoperative angiograms reveals several factors accounting for the failure of internal maxillary artery ligation. These factors include incomplete ligation of vessels, alternative dominance of vessels, and reconstitution of flow through collaterals. Eleven such patients have been successfully treated with angiography and embolization. There was one complication of skin slough in the region of the columella. Embolization is a useful modality in the management of these difficult cases.
上颌内动脉结扎术在治疗鼻出血方面是有效的。偶尔，患者在该手术后可能会继续出血。术后血管造影评估揭示了几个导致上颌内动脉结扎术失败的因素。这些因素包括血管结扎不完全、血管优势替代以及通过侧支循环重建血流。11例此类患者已通过血管造影和栓塞术成功治疗。在鼻小柱区域出现了1例皮肤坏死的并发症。栓塞术是处理这些疑难病例的一种有用方法。
