缺血性脑血管病介入诊断和治疗的临床研究

目的采用数字减影血管造影(DSA)对缺血性脑血管病患者进行介入诊断,分析血管内支架成形术介入治疗缺血性脑血管病的临床疗效。方法选取2002年1月至2012年11月期间入住我院的100例缺血性脑血管病患者为研究对象,利用DSA对其进行介入诊断,并选出符合介入治疗的64例进行支架成形手术治疗,观察DSA诊断结果,分析介入治疗效果及不良反应发生情况。结果 100例缺血性脑血管病中患有脑血管和头颈部大血管病变76例,病变血管84支。64例行支架成形术患者均成功放置支架,成功率达到100%,血管都得到不同程度的扩张,8例出现心率变缓等不良反应。结论对缺血性脑血管病进行DSA介入诊断,可为介入治疗提高评估依据。支架成形术是一种有效介入治疗手段,其具有良好的临床治疗效果。

DSA Diagnosis of Carotid Body Tumor

Objective: To make a further understanding of the DSA features of the carotid body tumor (CBT) and to explore the clinical value of DSA diagnosis and interventional treatment for CBT. Methods: Twelve cases of CBT with DSA data were analyzed retrospectively. The DSA appearances in all of the patients were observed dynamically in a double blind manner by two experienced radiologists together and a consensus interpretation formed. Results: DSA could establish definitive diagnosis in all cases. The DSA features of the CBT were: the increase of bifurcation angles of internal and external carotid arteries in all cases; the CBT supplied by external carotid arteries in most cases and the significant increase of tumor vessels in bifurcation; invasion of internal or external carotid arteries in 6 cases. The tumor staining disappeared mostly after the supplying arteris were embolized in 2 cases, and the bleeding during the operation reduced significantly. Conclusion: The DSA is useful in the diagnosis of the CBT and for therapeutic planning. The pre-operation embolization of the CBT contributes to reduce the bleeding during operation.

颅外段脑动脉狭窄70例介入诊断和治疗

目的通过对颅外段脑血管狭窄患者进行介入诊断及治疗,了解呼伦贝尔地区缺血性脑血管病患者的血管情况,并评价介入治疗的疗效及安全性。方法选取2009年8月至2014年1月入住呼伦贝尔市人民医院的70例颅外段脑动脉狭窄患者为研究对象,利用数字减影血管造影(DSA)技术对其进行介入诊断,并选出符合介入治疗的38例患者进行血管成形支架置入术,观察介入治疗效果、不良反应发生情况及预后情况。结果 70例颅外段脑动脉狭窄患者中有介入治疗指征的有38例,总共病变血管43支,均成功放置支架,成功率达到100%,血管都得到不同程度的扩张,缺血得到不同程度的改善,1例出现心率变缓的不良反应。结论对颅外段脑动脉狭窄进行DSA介入诊断及治疗,是一种有效的介入治疗手段,具有成功率高、安全性好、并发症少等优点。
