Methods and materials
31 patients ( 20 males and 11 females) with mean age of 54.5 years underwent balloon angioplasty using Maverick balloon catheter(Boston scientific) with <80% vessel diameter under general anesthesia.
Clinical presentation mainly included recurrent Transient ischemic attacks and minor strokes despite being on double anti platelet regimen.Inclusion criteria were smaller vessels (≤ 2-mm diameter),
longer lesions (>12 mm),
distal lesions,
tortuous vascular anatomy,
and vessels at branch points.
Patients who underwent stenting for ICAD in our institution were excluded from this study.19 lesions were in anterior circulation(11 M1,3 M2,4 ICA),
and 12 lesions(2 PCA,
7 Basillar and 2 in V4) were in posterior circulation.A combination of micro catheter and micro wire was used to cross the lesion in all the other patients .Maverick balloon less than 80% of the target vessel diameter was used to dilate the lesion with low atmosphere pressure(<6mm) with slow inflation for a time of 15 to 30 seconds under roadmap guidance.
Post procedure all the patients were closely monitored in the neurointensive unit for a minimum of 24 hours time period.All the patients were kept on dual antiplatelts and followed up clinically at one month,
3 months and 6 months interval.
