Aim:

This study aimed to evaluate the clinical outcomes of patients presenting with acute ischemic stroke, having large-to-medium vessel occlusion on pre-operative CT scans, and undergoing emergency mechanical thrombectomy.

Method:

Patients who presented to the emergency department of Istanbul Fatih Sultan Mehmet Training and Research Hospital with acute ischemic stroke and underwent mechanical thrombectomy between May 1, 2025, and November 1, 2025, were retrospectively reviewed. The demographic and clinical characteristics, procedural success, and post-procedure clinical outcomes of the 62 patients were evaluated.

Results:

The mean age of the 62 patients in our study was 64.7 (min. 37 - max. 99), and 32 (51.6%) of these patients were female and 30 (48.4%) were male. When the patients’ medical histories were examined, 34 (54.8%) had HT, 22 (35.5%) had AF, 17 (27.4%) had CAD, and 13 (21%) had DM. The average time from symptom onset to the start of the procedure was 228 minutes (min. 55 - max. 617). Regarding hemorrhagic complications, hemorrhagic transformation was observed in 25% of the patients, with only 1 reaching a life-threatening level. Successful reperfusion was achieved in 54 (87.1%) of the patients, and 3-month MRS scores showed that 49 (79%) patients achieved a good clinical outcome. When comparing large and medium-sized vessel occlusions from an MRS perspective, no significant difference was observed between the two groups(p:0.834)

Conclusions:

Mechanical thrombectomy is a safe and successful method for patients presenting with acute ischemic stroke and large-to-medium vessel occlusion. Studies conducted over the last 10 years have shown that mechanical thrombectomy, particularly in cases of large vessel occlusion, is associated with good clinical outcomes, and current guidelines recommend mechanical thrombectomy for this patient group. In our study, when we examined the 3-month MRS scores in patients who underwent thrombectomy, we observed an acceptably good clinical outcome.
