Neurogenic Pulmonary Edema Caused by Subarachnoid Hemorrhage: A Case Report

Neurogenic pulmonary edema is a serious and life-threatening complication caused by central nervous system diseases, excluding cardiogenic pulmonary edema, other causes of pulmonary edema, lung injury, etc. The lack of specific diagnostic criteria for NPE and the lack of awareness among clinicians often lead to underdiagnosis and misdiagnosis. The disease progresses rapidly with poor prognosis and high mortality [1]. In this paper, we report a patient with a ruptured right middle cerebral artery aneurysm causing subarachnoid hemorrhage, who developed neurogenic pulmonary edema and underwent elective aneurysm clamping under general anesthesia. The relevant perioperative management is reported as follows, and the anesthesia management of patients with neurogenic pulmonary edema is analyzed in the context of the relevant literature.

De novo aneurysm formation after the contralateral middle cerebral aneurysm clipping operation: a case report and review of literature

A left middle cerebral artery aneurysm was ruptured and clipped, but a de novo aneurysm on contralateral side ruptured within 5 years in a 38-year-old man. The cause of the formation of de novo aneurysms is unknown and is not consistent with most of current reports.
