Sixtyone patients with pancreatic cancer were treated with transcatheter celiac and superior mesenteric arterial anticancer agents (MMC 20mg, EADM 40mg and 5FU 20g) infusion (TCSAI).RESULTS The DSA diagnoses were confirmed by operations and pathological examinations, with a coincidence 826% rate of, and a therapeutic effective rate of 426%.CONCLUSION DSA is of diagnostic value for pancreatic tumors, and helpful in understanding the course of the disease, judging the prognosis and selecting the therapeutic regimen, and could improve the chemotherapeutic effect as well..展开更多

Methods： 24 HCC patients, 30 times DSA were examined, serum VEGF level was measured with the quantitative enzyme linked immunosorbent assay （ELISA） in patients and healthy control subjects in this study. Results： Among DSA for 24 patients with HCC, 18 of 24 cases showed hepatic artery blood supply of tumor. Four of 24 cases showed portal vein blood supply of tumor, 1 of 24 cases showed superior mesenteric artery blood supply of tumor and artery-venous shunt formation, and there was no blood supply to tumor in one case. Serum VEGF level in HCC[（χ＋s）194.5±14.2] ng/L was significant elevated to those in patients comparing with those of the normal controls （132.4±47.9） ng/L and marked differences （P〈0.01）. Conclusion： During the cases for plenty blood supply or arteryvenous shunt formation in patients with HCC, serum VEGF level markedly elevated in the patients of HCC. VEGF expression was significantly related to intrahepatic dissemination, recurrence and metastasis in patients with HCC.展开更多
目的:探讨三维数字减影血管造影(three-dimension digital subtraction angiography,3D-DSA)在脑血管疾病诊断中的应用价值。方法:对临床怀疑脑血管疾病患者208例,同时进行常规DSA(2D-DSA)和3D-DSA检查,并对结果进行对比分析。结果:208...目的:探讨三维数字减影血管造影(three-dimension digital subtraction angiography,3D-DSA)在脑血管疾病诊断中的应用价值。方法:对临床怀疑脑血管疾病患者208例,同时进行常规DSA(2D-DSA)和3D-DSA检查,并对结果进行对比分析。结果:208例中,检出动脉瘤128例,脑动脉狭窄或闭塞29例,动静脉畸22例,烟雾病10例,脑肿瘤4例。2D-DSA病变检出率80.3%(167/208);3D-DSA病变检出率92.8%(193/208);两组检出率差异具有统计学意义(P<0.05)。结论:3DDSA在脑血管疾病诊断中具有重要的应用价值,是2D-DSA的优化和补充。展开更多
