Abstract
Introduction
The standard treatment for acute ischemic stroke is intravenous (IV) rtPA for patients
who can reach the hospital within 3 to 4.5 h. There are case reports, where IA thrombolysis
has helped patients in case an IV thrombolysis has failed. We report 14 cases of acute
ischemic stroke treated by intra-arterial (IA) thrombolysis.
Materials and Methods
We have retrospectively analyzed 14 cases of acute ischemic stroke treated at our
department between December 2008 and October 2011 by intra-arterial thrombolysis.
The patients with suspected large vessel occlusion (11 patients) and patients not
responding to IV rtPA (3 patients) were considered for the IA thrombolysis.
Results
We achieved complete recanalization (TIMI 3) in 11 patients. One patient had a bleed
following the procedure but recovered well during the hospital stay. All the patients
were followed up to 90 days. Majority of them have good functional outcome.
Conclusions
Our study suggests that intra-arterial thrombolysis is a feasible option in the subgroup
of patients with large vessel occlusion. However, there is a need for a randomized
multicentric study to support our results.
