Video Summary

In this video, Dr. Namir Adib discusses the risk of branch occlusion and ischemic complications with the pipeline embolization device in the treatment of posterior circulation aneurysms. He explains that the pipeline has become an important treatment modality for intracranial aneurysms but is limited by the risk of branch occlusion and subsequent ischemic stroke. Dr. Adib presents findings from a study that assessed this risk and factors that may predict branch occlusion and ischemic complications. The study collected data from multiple centers and found that branches with rich collateral supply, such as the vert and PCA, had a higher occlusion rate. However, most occlusions were asymptomatic. The study also found that intraaneurysm thrombosis was associated with a higher risk of thromboembolic complications. Overall, the study suggests that end arteries tend to remain open after pipeline coverage, while branches with collateral supply are more likely to occlude.
