The objective of this study was to investigate and discuss the effect of direct angioplasty therapy on acute middle cerebral artery occlusion (MCAO) patients with good leptomeningeal collateral circulation in 4.5 h.
We retrospectively reviewed our acute ischemic stroke database from January 2017 to January 2019, then selected consecutive patients with evidence of the proximal M1 segments of MCAO and good leptomeningeal collateral who have received angioplasty or mechanical thrombectomy (MT). The baseline characteristics and outcome of patients was statistical analysis, included age, gender and risk factors, baseline national institutes of health stroke scale (NIHSS) scores, preoperative alberta stroke programme early CT (ASPECT) score, time from door to needle, time of door to puncture, endovascular procedure time, 7d NIHSS score and the modified treatment in cerebral infarction (m-TICI) 2b or 3, symptomatic hemorrhage, average hospital stays, modified rankin scale (mRS) score 0-2 at 3-month and mortality. All the thrombi were analyzed by histopathology. All statistical analysis was done with t-test for continuous data and χ2 test for binary data.
A total of 93 patients were included (direct angioplasty = 41 (44.1 %), MT = 52 (55.9 %)). There was no significant difference in baseline data between the two groups. The difference in the time of door to recanalization, the time of puncture to recanalization, symptomatic hemorrhage, and average hospital stays were significantly different between groups (P < 0.05). The other agents were not significantly different between groups (P > 0.05 each). Histopathological analysis showed all thrombi contained different amounts of platelets, fibrinogen, white blood cell, and red blood cell.
Direct angioplasty therapy on acute MCAO with good leptomeningeal collateral may help to shorten the time of surgery, reduce symptomatic hemorrhage, and hospital stay.
