[Complications of mechanical thrombectomy].

Clinical Problem: Ischemic stroke is the most common cause of disability in adults and an important disease for society; therefore, the prevention, diagnosis, and treatment play an important role. Endovascular mechanical recanalization to reopen large occlusions of the intracerebral vessels has established itself as the gold standard in therapy, which is why knowledge of the most important complications and their management is essential for interventionalists.

Practical Recommendations: Intracranial hemorrhages, which include intracerebral and subarachnoid hemorrhages, are dreaded complications that significantly worsen the clinical outcome. Early monitoring and optimal management are therefore essential. Cerebral air embolism is a rare but dangerous complication whose prevention is paramount, as treatment options are limited.
