Studies from Beth Israel Deaconess Medical Center in the Area of Aneurysm Described (Sequential Hemodynamic Analysis of Ruptured Posterior Communicating Artery Aneurysms Treated With Coil Embolization and Delayed Flow Diversion).

A study conducted at Beth Israel Deaconess Medical Center in Boston, Massachusetts, analyzed hemodynamic changes in patients with ruptured posterior communicating artery aneurysms treated with acute coiling and delayed flow diversion. The research found that after coiling, there was a reduction in aneurysmal volume and an increase in wall shear stress, with complete occlusion achieved after delayed flow diversion. The study concluded that low shear areas may have contributed to aneurysm rupture, and delayed flow diversion caused hemodynamic disturbances distal to deployment. The findings provide valuable insights into the treatment of posterior communicating artery aneurysms. [Extracted from the article]
