Beware of the aneurysm in stealth mode!

Endovascular treatment is one of the treatment options considered for acute stroke in many primary stroke centers. Outcome from such treatment can be very successful and gratifying if the intervention is timely and patient selection is appropriate. There are however certain pitfalls that need to be kept in mind which, if the interventionalist is not careful, can adversely affect the outcome. We describe such a case where the patient presented with acute stroke due to basilar artery thrombosis but also had an aneurysm in the affected vessel. We also make certain recommendations to reduce the chances of complications arising during treatment of patients with such a condition.
