Abstract:
Objective: To provide a better displayed method in order to avoid damaging the posterior circulation perforators in neurointervention surgery.
Methods: Eighty patients in our hospital from March to July 2017 treated with posterior circulation cerebral brain DSA examination were randomly divided into control group (normal vertebral artery angiography, 40 cases) and experimental group (optimized vertebral artery angiography, 40 cases) . The basilar artery and proximal posterior cerebral artery on both sides were observed in different modes after angiography, and differences of the numbers of each segments perforators were counted in both groups.
Results: To compare the two groups after angiography, we found that the average numbers of perforators in P1 segment were 2.00±1.01 and 1.95±1.10 on left and right sides in experimental group, vs. 1.52±0.71 and 1.45±0.81 in control group; 1.45±0.99 and 1.43±1.15 vs. 0.78±0.65 and 0.55±0.55 in P2 segment; 1.87±0.88 and 1.80±1.07 vs. 0.37±0.54 and 0.28±0.50 in both sides of the pons perforators artery of basilar artery. The number of perforators in each part of the control group was less than that of the experimental group, the difference had statistical significance (P<0.05) .
Conclusions: The optimized vertebral artery angiography method can effectively show the numbers and direction of perforators of posterior circulation during the encephalon angiography examination, which can guide neurointervention surgery and prevent to damage the related perforators in neurointervention.
