摘　　要：目的 总结不同侵袭危险程度小肠间质瘤的数字减影血管造影（DSA）表现。方法 回顾性分析2008年9月至2010年6月四川大学华西医院收治的以消化道出血为首发症状、经病理学检查证实的15例小肠间质瘤患者的临床资料，总结其不同侵袭危险程度的DSA征象。结果 15例患者中1例极低度侵袭危险程度的肿瘤DSA检查示动脉期见引流静脉，边缘清晰，肿瘤染色均匀；4例低度侵袭危险程度的肿瘤DSA检查示供血动脉增粗、边缘清晰，肿瘤染色均匀；4例中度侵袭危险程度的肿瘤DSA检查示动脉增粗紊乱，形态不规则，其中3例肿瘤染色不均匀；6例高度侵袭危险程度的肿瘤DSA检查见肿瘤血管明显增粗紊乱、边缘模糊，肿瘤染色不均匀。结论 小肠间质瘤侵袭危险程度越高，DSA检查示肿瘤血管越不规则、紊乱；而侵袭危险程度越低肿瘤血管越规则、整齐。Objective To summarize the features of signs of digital subtraction angiography （DSA） of small intestinal stromal tumor （SIST） with different invasion risk degrees. Methods The clinical data of 15 patients with SIST who were admitted to the West China Hospital of Sichuan University from September 2008 to June 2010 were retrospectively analyzed. The signs of DSA of SIST with different invasion risk degrees were analyzed.Results The result of DSA showed that 1 patient with lowinvasive SIST presented draining veins and clear edge with homogeneously stained tumor in arterial phase. Enlarged tumors vessels, sharp edges and uniform tumor staining were observed in 4 patients with lowinvasive risks. Enlarged and disordered tumor vessels and irregular shape were observed in 4 patients with moderateinvasive risks, and 3 of them showed heterogeneity stained tumor. Obvious enlarged and disordered tumor vessels, unclear edge and uniform tumor staining were showed in 6 patients with highinvasive risks. Conclusions The higher invasive risks correlates with more irregular and disorder tumor vessels. The tumors with lowerinvasive risks have more regular and trim blood vessels.
