First report of validation of the prognostic nutritional index in patients with subarachnoid hemorrhage undergoing endovascular occlusion or surgical clipping.

Purpose: The study aims to investigate the effect of prognostic nutritional index (PNI) on the outcome of patients with SAH undergone endovascular occlusion or surgical clipping.

Methods: Clinical data of consecutive patients with SAH patients who were managed in the neurosurgical department of Kanuni Research and Training Hospital in Trabzon from January 2020 to June 2022 was analyzed. The primary endpoint was early mortality in one month.

Changes in retinal nerve fiber layer thickness may be the cause of post-COVID-19 headaches.

Objective: The prevalence of post-COVID headaches is not low. The eye can be affected by this infection, but it is not clear yet what the relationship is between persistent headaches and the thickness of the retinal nerve fiber layer (RNFL) after COVID-19 infection this study aims to investigate the relationship between these subjects.

Methods: In this retrospective study, in patients who have had a persistent headache, SD-OCT analysis of RNFL was obtained, and RNLF thickness values before and after COVID-19 infection were analyzed.

New histopathological evidence for the relationship between hydromyelia and hydrocephalus following subarachnoid hemorrhage: An experimental study.

Objectives: Subarachnoid hemorrhage (SAH) is a serious pathology with a high death and morbidity rate. There can be a relationship between hydromyelia and hydrocephalus following SAH; however, this subject has not been well investigated.

Materials And Methods: Twenty-four rabbits (3 ± 0.

Overlooked evidence for transmission deficit of pupillary light reflex can be secondary to trigeminal nerve ganglion degeneration following subarachnoid hemorrhage; preliminary experimental study.

Objective: Although the effect of oculomotor and cervical sympathetic networks on pupil diameter is well known; the effect of the trigeminal nerve on pupil diameter has not been investigated yet. This subject was investigated.

Materials And Methods: Five of 23 rabbits were used as a control group (GI;  = 5); 0.

Flow diverter stent treatment for unruptured supraclinoid segment internal carotid artery aneurysms: a Turkish multicenter study.

Objective: Despite the relatively high success of surgical clipping of supraclinoid segment aneurysms of the internal carotid artery (ICA), flow diverter (FD) stent therapy is becoming increasingly used for these aneurysms. This study aims to evaluate the characteristics of FD placement for unruptured ICA supraclinoid segment aneurysms at 6 different centers with different experience levels in Türkiye.

Methods: In this retrospective, multicenter study, the authors reviewed the demographic information, aneurysm shape/dimensions (neck, aspect ratio, dome/neck ratio, and maximum diameter), preoperative antiplatelet regimen, FD stent brand, perioperative complications, intervention time, clinical (modified Rankin Scale) and radiological (O'Kelly-Marotta [OKM] grading scale) outcomes, and follow-up time of 54 patients.
