Strategies for managing left main trunk compression by left atrial appendage clip: a case report.

Background: Closure of the left atrial appendage (LAA) using a clip in at-risk patients reduces stroke risk. The rate of LAA closure procedures is increasing worldwide; however, complications have been reported, with coronary compression being one possible lethal complication associated with the anatomical structures around the LAA.

Case Summary: A 75-year-old man presented with a diagnosis of a φ50 mm saccular thoracic aortic aneurysm.

[Failed Surgical Clipping of a Posterior Communicating Artery Aneurysm with Oculomotor Nerve Palsy due to Ventricular Tachycardia:Validity of Endovascular Coiling in the Hybrid Operating Room].

Unruptured posterior communicating artery aneurysms with oculomotor nerve palsy are at high risk of rupture, and early intervention is recommended to prevent aneurysm bleeding and to improve oculomotor function. Both surgical clipping and endovascular coiling are available, and either of them is applied according to the anatomical condition and patient's comorbidity. In this article, we describe a case of an unruptured posterior communicating artery aneurysm with oculomotor nerve palsy, which was initially treated with surgical clipping.
