Arterial hemorrhage, pseudoaneurysms, and arterial-enous fistulas, howeer, require prompt interention with angiographic embolization. 但是，動(dòng)脈出血，假性動(dòng)脈瘤以及動(dòng)靜脈瘺需要血管造影栓塞進(jìn)行急診干預治療。
Although arterioenous fistulas are considered superior to grafts, it is unknown whether that is true in the subset of patients with a preious failed fistula. 雖然動(dòng)靜脈瘺是在移植血管前的優(yōu)先選擇，但是在瘺閉患者這一亞組中還不清楚動(dòng)靜脈瘺是否依然是正確的首選。
