Nine patients underwent transcatheter embolization with a suspension of microfibrillar collagen hemostat (MCH). Four of the patients had large vascular renal tumors, and two had bleeding bladder carcinomas. There was one case each of bleeding rectal tumor, bleeding esophageal varices, and arteriovenous malformation of the shoulder. MCH was highly thrombogenic and could be injected through very small catheters. It was highly effective as an occlusive agent and was able to penetrate the small end-arteries of a lesion. Its main disadvantage is that if normal tissues are inadvertently embolized, there is a risk of ischemic complication.
9名患者接受了微纤维胶原止血剂（MCH）悬浮液的经导管栓塞治疗。其中4例患者患有大型肾血管肿瘤，2例患有出血性膀胱癌。分别有1例出血性直肠肿瘤、出血性食管静脉曲张和肩部动静脉畸形。MCH具有高度血栓形成性，可通过非常细的导管注射。作为一种闭塞剂，它非常有效，能够穿透病变的小终末动脉。其主要缺点是，如果无意中栓塞了正常组织，存在缺血性并发症的风险。
