Posterior circulation aneurysms are more likely to rupture than those in the anterior circulation but also pose more of a challenge for endovascular treatment or neurosurgical clipping. Aneurysms arising from the posterior cerebral artery are rare; dissecting aneurysms are even rarer. Dissecting posterior cerebral artery aneurysms can be spontaneous or post traumatic. Our case depicts a patient with acute subarachnoid hemorrhage due to a ruptured, dissecting posterior cerebral artery aneurysm who underwent successful endovascular treatment by means of flow diversion.

Intraoperative rupture is the most important complication of aneurysm surgery1-5 and occurs in 3 different stages: premature (before dissection), dissection, and clipping.5 We present a video of premature rupture and its management (Video 1). A 45-year-old patient presented with subarachnoid hemorrhage originating from a dorsal internal carotid artery (ICA) aneurysm of the communicating segment. Due to our sufficient experience, we preferred direct clipping in this case. ⋯ In the literature review including 10,540 cases,1 the mean incidence of IOR is 16.6%. Therefore every neurosurgeon should be prepared for this important complication and know its management well. This case reminds us once again the golden rule of aneurysm surgery: proximal control first.

THE ROLE OF PLASMA COPEPTIN LEVEL IN DETERMINING THE SEVERITY AND MORTALITY OF SUBARACHNOID HEMORRHAGE.
The study aimed to investigate the role of plasma copeptin level in setting the diagnosis, severity and mortality of patients with subarachnoid hemorrhage (SAH) admitted to the emergency department. We included patients aged ≥18 years who were diagnosed with SAH. Blood samples were collected from patients at the time of admission to the emergency department for assessment of plasma copeptin levels. ⋯ There was no significant correlation of plasma copeptin levels with the GCS, WFNS, and modified Fisher scores. There was no significant difference in copeptin levels between the patients who died in the hospital (mean: 0.73±0.42 ng/mL) and those who did not (mean: 0.80±0.41 ng/mL) (p=0.41). Although plasma copeptin level may be used in the diagnosis of SAH, it does not have a role in determining the patient condition severity and mortality.

As a common hemorrhagic cerebrovascular disease, subarachnoid hemorrhage (SAH) has high mortality and disability. Delayed cerebral ischemia (DCI) is among the major complications after SAH, severely affecting the patient prognosis. Through bibliometric analysis, this study investigated the global research status, trends, and hotspots of DCI after SAH from 2013 to 2022, providing a scientific reference for researchers in this field. ⋯ DCI after SAH has drawn increasing interest in academic circles during the past decade. This study presented an objective, systematic, and comprehensive analysis of the literature on DCI after SAH. Currently, the hotspots in this field focus on pathophysiological mechanisms.
