Introduction Cerebral vasospasm (CVS) is a frequent complication following subarachnoid hemorrhage (SAH). The most interventional and pharmacological measures are only effective for short periods.

Recently, studies have shown a possibly beneficial effect of the treatment of CVS following SAH through stent-retriever devices. We report our experience with the new pRELAX traction maneuver and device in the treatment of CVS.

Aim of Study Our aim is to show that the pRELAX traction maneuver is both safe and effective in our small experience.

Methods We treated six patients suffering from posthemorrhagic CVS using pRELAX Traction Maneuver.

We temporarily deployed the pRELAX device into CVS affected vessels and pulled it back unfolded into the internal carotid artery; in a technique comparable to endovascular thrombectomy.

Angiographic results, periprocedural complications and angiographic follow-up data were recorded.

Results Six patients and thirteen vessels were included (8 middle cerebral artery; 5 intradural internal carotid artery). There were no periprocedural complications and all vessels showed significant angiographic improvement already during the treatment. None of the treated vessels showed recurrent CVS requiring further endovascular treatment. No new ischemia were found in the treated vessels territories and no vascular injury was seen on follow-up angiographies.

Conclusion The treatment of CVS with the new pRELAX traction maneuver showed promising results in our experience, at a low risk and with favorable in-hospital course of the patients. Since the treatment options of CVS following SAH are limited, this initiative may pose a long sought measure to prevent ischemic complications for patients surviving SAH.
