Therapeutic effect of pre-operative tirofiban on patients with acute ischemic stroke with mechanical thrombectomy within 6

Abstract

Objective

The objective of this study was to investigate and discuss the therapeutic effect of pre-operative tirofiban on patients with acute ischemic stroke (AIS) with mechanical thrombectomy (MT) within 6–24 h.

Patients and methods

We retrospectively queried our AIS database from January to November 2018, and selected 99 patients with AIS within 6–24 h and evidence of proximal large vessel occlusion who were suitable for MT. They were divided into two groups, group A (with tirofiban, n = 56) and group B (without tirofiban, n = 43), according to whether they were intravenously infused with tirofiban before MT. The baseline characteristics and outcomes of patients were subjected to statistical analysis, including age, gender and risk factors, occlusion site, the time from onset to door, time of door to puncture, baseline National Institutes of Health Stroke Scale (NIHSS), pre-operative Alberta stroke programme early CT (ASPECT) score, angioplasty/stenting, modified Rankin Scale score 0–2 at 3 months, symptomatic haemorrhage and mortality, the time of door to recanalization, endovascular procedure time, 7-day (7d) NIHSS score, and a modified treatment in cerebral infarction (m-TICI) grade of 2b or 3. All of the thrombi were analysed by histopathology.

Results

The differences in the time of door to recanalization, endovascular procedure time, 7d NIHSS score and the m-TICI were significantly different between groups (P < 0.05). The other agents were not significantly different between groups (P > 0.05 each). Histopathological analysis showed that all thrombi contained different amounts of platelets, fibrinogen, Haemamoebas and red blood cells.

Conclusion

The use of tirofiban before MT can shorten the procedure time and improve the recanalization rate of occluded vessels in AIS patients.
