Extended Retrosigmoid Approach for Resection of a Lateral Pontine Arteriovenous Malformation: 2-Dimensional Operative Video

Pontine arteriovenous malformations (AVMs) are uncommon lesions, with few reports in the literature. The best treatment option is debated, with options including surgical resection, endovascular embolization, and radiosurgery. Patient consent for the procedure was obtained. Herein, we report the successful resection of a ruptured lateral pontine AVM with an associated aneurysm in a woman in her early 70s. Surgical resection can be considered an effective treatment option for brainstem AVMs and should be considered alone or in conjunction with other treatment modalities.
