目的:探讨DSA诊断小肠血管畸形的价值。方法:本文分析21例小肠血管畸形患者的临床及DSA特征,其中男性14例,女性7例,所有患者均行肠系膜上、下动脉造影。结果:临床特征:①急性消化道出血为主症状;②常规检查一般为阴性;③血红蛋白含量短期内降至4~6 g/mL。DSA特征:①动静脉瘘;②局部肠壁染色增浓;③局部血管异常增多,结构紊乱。其中12例进行了动脉导丝栓塞,2例栓塞后出血,进行外科手术切除。结论:DSA是诊断血管畸形所致小肠出血的最有效的方法,动脉导丝栓塞是安全,有效的治疗方法,同时为外科手术切除提供的正确部位。
Objective: To investigate the value of DSA in the diagnosis of intestinal vascular malformations. Methods: The clinical and DSA features of 21 patients with small bowel vascular malformations were analyzed. Among them, 14 were male and 7 were female. All patients underwent superior mesenteric and inferior arteriography. Results: Clinical features: ① acute gastrointestinal bleeding as the main symptom; ② routine examination is generally negative; ③ hemoglobin content decreased to 4 ~ 6 g / mL in the short term. DSA features: ① arteriovenous fistula; ② partial thickening of the intestinal wall staining; ③ local vascular abnormalities increased, structural disorders. Among them, 12 cases had arterial guidewire embolization, 2 cases had hemorrhage after embolization and were surgically removed. Conclusion: DSA is the most effective method to diagnose intestinal bleeding caused by vascular malformations. Arterial catheter embolization is a safe and effective method of treatment, and at the same time provides the correct site for surgical resection.
