【摘要】：目的探讨Stanford B型主动脉夹层原发破口位置对腹腔主要分支动脉血流灌注的影响。方法回顾性分析130例Stanford B型主动脉夹层患者术前主动脉CTA资料,对受累的腹腔主要分支血管(腹腔干、肠系膜上动脉、双侧肾动脉)缺血类型和灌注损伤程度进行分型,并分析二者与不同夹层原发破口位置的关系。结果 130例患者共计542支分支动脉中,465支(465/542,85.79%)存在缺血,包括337支(337/542,62.18%)动力型缺血及128支(128/542,23.62%)静力型缺血,其中灌注受损69支(69/542,12.73%)、灌注未受损396支(396/542,73.06%);77支(77/542,14.21%)血管无缺血。灌注受损的分支血管中,动力型缺血37支(37/69,53.62%),静力型缺血32支(32/69,46.38%),差异无统计学意义(χ~2=3.077,P=0.215)。夹层原发破口位置对腹腔主要分支动脉缺血类型(动力型、静力型)及灌注改变情况(受损、未受损)无明显影响(χ~2=1.352、0.776,P=0.509、0.678)。结论 B型主动脉夹层原发破口的位置对腹腔主要分支动脉缺血类型及灌注损伤程度无明显影响,评估腹腔主要分支血管缺血及灌注改变情况对指导手术方案制定有重要临床意义。
[Abstract]:Objective to investigate the effect of primary opening position of Stanford B aortic dissection on blood perfusion of main branches of abdominal cavity.Methods Aortic CTA data of 130 patients with Stanford B aortic dissection before operation were retrospectively analyzed. The types of ischemia and perfusion injury of the main branches of abdominal cavity (celiac trunk, superior mesenteric artery, bilateral renal artery) were classified.The relationship between them and the location of the original break in different interlayer is analyzed.Conclusion the location of the primary opening of type B aortic dissection has no significant effect on the type of ischemia and the degree of perfusion injury of the main branches of abdominal cavity.It is important to evaluate the changes of ischemia and perfusion in the main branches of abdominal cavity.
