RESUMEN
Objective:To investigate the application of side branch protection technique in interventional treatment of intracranial arteriosclerosis stenosis.Methods:We reviewed the patients who underwent interventional treatment of intracranial arteriosclerosis stenosis from November 2018 to May 2021 in Affiliated Drum Tower Hospital of Nanjing University Medical School, and analyzed the role of side branch protection technique in the prevention and treatment of complications. Relevant evaluation indicators including: (1) imaging: patency of blood flow in target vessels and branch vessels; (2) clinical presentation: ischemic stroke or transient ischemic attack (TIA) events within 72 hours and one month follow-up results.Results:A total of 9 patients underwent side branch protection during interventional treatment for intracranial arteriosclerosis stenosis, the blood flow of target vessels was improved obviously after operation, and the blood flow of the affected branches was not affected; no stroke or TIA events occurred in 72 hours after operation and one month follow up.Conclusions:Proper application of side branch protection technique can reduce the perioperative complications effectively during the interventional treatment for intracranial arteriosclerosis stenosis.
RESUMEN
Objective To evaluate the feasibility of jailed-balloon technique(JBT) in the treatment of true coronary bifurcation lesions.Methods From March 2013 to October 2014,a total of 71 patients who received coronary angiography,were diagnosed as true coronary bifurcation lesions and then underwentpercutaneous coronary intervention(PCI) in the Department of Cardiology of the Second Affiliated Hospital of Kunming Medical University was divided into group A(jailed balloon side branch protection group,28 cases) and group B(traditional side branch protection group,43 cases).The perioperative complications,X-ray exposure time,the number of intervention supplies,the total expenses,the incidence of adverse cardiovascular events and other indicators between the groups were compared,and the feasibility of JBT was evaluated.Results There were no significant differences between the two groups in perioperative complications(P＞0.05),postoperative adverse cardiovascular events and restenosis rate of side branch after angiography(P＞ 0.05),but the PCI related indicators (including the balloon use number,PCI operation time,the amount of X-ray exposure,wire number,the amount of contrast agent and operation cost) in group A were significantly lower than those in group B(P＜0.05).Conclusion JBT applied in the treatment of true coronary bifurcation lesions can reduce the operative time,X-ray irradiation time and related medical expenses.
