Introduction Mechanical thrombectomy (MT) is now accepted as a standard treatment for the treatment of patients with ischemic stroke due to large vessel occlusions (LVO) in the anterior circulation.

Aim of Study Intracranial hemorrhage is one of the most feared complications following brain infarction and is strongly associated with poor outcomes. We wanted the demonstrate different situations of procedure-related hemorrhagic complications during MT for LVO in order to try to prevent them in future and to anticipate appropriate reaction when they acure.

Methods We retrospectively analyzed 380 conscecutive patients treated with MT in the University Clinical Centre of Serbia performed from January 2018 to May 2023 for hemorrhagic complications. All the details of periprocedural events were notified and patients were radiologically and clinically followed. Technical outcome was accessed by mTICI scale and clinical outcome by 3 months mRS.

Results In our cohort, we found 4 procedure-related hemorrhagic complications, two of the patients died and the other two recovered to the level of mRS 5 and 2.

Conclusion Procedure-induced hemorrhage complications are rare and potentially disastrous events of which interventionalists need to be aware and be prepared for adequate endovascular solutions.
