Objective: To evaluate the efficacy and safety of adenosine induced asystole during the intra-arterial injection of nBCA, aiming at controlled endovascular occlusion of intracranial vessels.
Method: A retrospective analysis of patient files and procedure documentations was performed. Between August 2010 and July 2014, adenosine induced asystole was applied in 29 consecutive procedures, performed in 24 patients (12 female). A total of 21 AVMs, 4 dural AV fistulas, 3 intracranial aneurysms and 1 arterial vessel injury were treated. The procedures were evaluated according to the following criteria:
- 1.
- was asystole achieved?
- 2.
- was the nBCA injection sufficiently controlled?
- 3.
- was a complication of the adenosine injection encountered?
- 4.
- did the nBCA embolization cause adverse effects, related to venous passage or arterial displacement?
Results: Asystole was induced in all 29 attempts. The injection and propagation of nBCA was well controlled in all procedures. All patients returned spontaneously to rhythmic cardiac action, without any circulatory issues. No complication related to venous passage or distal arterial migration of nBCA was observed.
Conclusions: Adenosine induced asystole per se is safe. In high-flow arteriovenous shunts and in rare arterial embolizations (e.g., dissecting aneurysm occlusion), nBCA injection is well controlled if performed under cardiac arrest.
