Objective To study the feeding arteries of sacral tumors with digital substraction angiography (DSA). Methods A total of 27 patients with sacral tumors, who were encountered at authors’ hospital during the period from January 2006 to December 2012 , were enrolled in this study. DSA of abdominal aorta, bilateral internal iliac arteries, median sacral artery and lumbar arteries was performed in all patients. The origins, branches of the feeding arteries were determined, and the results were analyzed. Results Of the 27 cases with sacral tumors, DSA demonstrated median sacral artery in 20 (20 arteries in total), lateral sacral artery in 22 (36 arteries in total), ilio-lumbar artery in 18 (27 arteries in total), lumbar artery in 10 (15 arteries in total), inferior gluteal artery in 3 (3 arteries in total) and superior gluteal artery in 2 (2 arteries in total). Conclusion In our series, the blood supply of the sacral tumors is mainly from the median sacral artery, lateral sacral artery, ilio-lumbar artery and lumbar artery. Occasionally, superior and inferior gluteal arteries also participate in the blood supply of the sacral tumors. For the evaluation of sacral tumors, attention should be paid to the presence of rare feeding arteries.

Objective:To systematically evaluate the clinical efficacy and safety of Xixian Tongshuan Capsules/Pills combined with Western medicine in treating cerebral infarction.Methods:All RCTs about Xixian Tongshuan Capsules/Pills combined with Western medicine in treating cerebral infarction were retrieved from CNKI, Wanfang Database, VIP database, PubMed and CBM. The search period was from the database establishment to December 31, 2021. Two researchers independently extracted the basic literature data and evaluated the methodological quality, then used RevMan5.4 software for meta-analysis.Results:Totally 9 articles were included, involving a total of 988 patients, including 505 cases in the observation group and 483 cases in the control group. Meta-analysis showed that the total effective rate of Xixian Tongshuan Capsules/Pills combined with Western medicine in treating cerebral infarction was higher than that of conventional Western medicine [ RR=1.20, 95% CI (1.13, 1.27), P<0.05]. At the same time, the effect of NIHSS score, Barthel score and FIB were better than those of conventional Western medicine [respectively: MD=-3.21, 95% CI (-4.45, -1.97), P<0.05; MD=11.83, 95% CI (10.66, 13.00), P<0.05; MD=-0.95, 95% CI (-1.36, -0.54), P<0.05]. After treatment with Xixian Tongshuan Capsules/Pills combined with Western medicine, the adverse reactions mainly included dizziness, nausea, indigestion, rash, facial blushing, etc. There was no statistically significant difference in safety between the two groups [ RR=1.50, 95% CI (0.75, 3.01), P>0.05]. Conclusions:Under the treatment of conventional Western medicine, the addition of Xixian Tongshuan Capsules/Pills can improve the clinical efficacy of cerebral infarction treatment, effectively improve the symptoms of neurological impairment, improve the ability of daily life, and promote the prognosis and recovery, and without increasing the incidence of adverse reactions. However, large sample and high quality studies are still needed to support the conclusion.
