Analysis of relevant factors and prognosis of intracranial high-density shadow after emergency endovascular intervention treatment
Objective To investigate the incidence and impacting factors of intracranial high-density shadow after emergency endovascular intervention treatment,and the correlation between high-density shadow and clinical prognosis.Methods A total of 100 stroke patients undergoing endovascular intervention treatment admitted to the First People's Hospital of Yibin from June 2020 to June 2021 were selected as the research object.Immediately after operation,the plain CT scan of the skull was reexamined to determine whether there was high-density shadows.The patients were divided into the high-density shadow group(n=52)and the non-high density shadow group(n=48).The preoperative National Institute of Health Stroke Scale(NIHSS),the modified Rankin scale(mRS),the alberta stroke program early CT score(ASPECTS),intraoperative American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology Collateral Vessel Grading System(ASTIN/SIR)classification,the modified thrombolysis in cerebral infarction(mTICI)after operation,and the good prognosis(mRS score≤3)rate after operation,etc.,were compared between the two groups of patients.Results The good prognosis rates at 3,6,and 12 months postoperatively for the 100 patients included in the study were 34.00%,52.00%,and 54.00%,respectively.It was discovered that there were all statistically significant differences in intraoperative ASTIN/SIR grade,postoperative mTICI recanalization grade and good prognosis rate for 3 months(P<0.05),while there were no statistically significant differences in other postoperative indices(P>0.05).Conclusion For patients with good collateral circulation,more caution should be exercised during operation,and postoperative attention should be paid to the condition.Imaging review and evaluation should be emphasized to reduce the impact of contrast agent extravasation on the prognosis of patients.
