Preoperative application of three-dimensional angiography in elderly patients with meningioma / 中华老年医学杂志

ABSTRACT

Objective To study the preoperative application value of the three-dimensional angiography in surgical strategy for the elderly patients with meningioma. Methods Forty-two elderly patients aged 60 years and over with meningioma were examined preoperatively with multi-slice spiral CT angiography(MSCTA) and (or) 3 dimensional contrast-enhancement MR angiography(3D CE-MRA)as simulation group.In three-dimensional post-processing workstation,the oppression and invasion degree of the intracranial important blood vessels,nervous running zone and sinus,as well as surgical risks were evaluated. 28 elderly patients without the above examination were as control group. The operation time, blood transfusions and postoperative complications were compared between the two groups. Results All 42 cases of simulation group completed reasonable surgical plan and approach.The incidence of postoperative complications were lower in simulation group than in control group (35.7％ vs.50.0％,P＞0.05),intra-operative blood transfusion were significantly decreased in simulation group as compared with control group [(5301.0± 150.6) ml vs.( 621.4±226.7)ml,t=2.01,P=0.049],operation time after three-dimensional simulation were reduced as compared with control group [(257.1 ±72.6) min vs.(307.5±88.2)min,t=2.61,P=0.011].Conclusions Application of three-dimensional angiography in elderly patients with meningioma to evaluate the operative risk may help make reasonable surgical strategy,thus reducing the surgical trauma and complications.
