Article Abstract
Background: This study aimed to investigate the relationship between neutrophil percentage-to-albumin ratio (NPAR) and collateral circulation in patients with chronic total occlusion (CTO). Chronic total occlusion is an advanced stage of coronary artery disease (CAD) and is characterized by complete occlusion of the coronary arteries. Collateral circulation provides alternative routes that supply blood flow instead of occluded arteries and may affect the prognosis of CTO patients. Neutrophil percentage-to-albumin ratio is recognized as an indicator of inflammation and can be used to predict the prognosis of various diseases.
Methods: In this retrospective study, 320 patients with CAD who were diagnosed with CTO by coronary angiography were included. Demographic characteristics, clinical findings, and laboratory test results were recorded. The degree of coronary collateral circulation was classified according to the Cohen-Rentrop method. Neutrophil percent-age-to-albumin ratio and other inflammatory parameters were measured. The relationship between NPAR and collateral circulation was evaluated using multivariate analysis.
Results: Neutrophil percentage-to-albumin ratio levels were significantly associated with poor collateral circulation. Neutrophil percentage-to-albumin ratio, together with other inflammatory parameters (white blood cell count, neutrophil-to-lymphocyte ratio, C-reactive protein), was identified as an independent marker of poor collateral circulation in CTO patients. Fasting blood glucose levels and diabetes mellitus were also associated with poor collateral circulation.
Conclusion: Neutrophil percentage-to-albumin ratio is emerging as a simple and effective inflammatory marker that can be used to predict the quality of collateral circulation in CTO patients. This is important for predicting the prognosis of CTO patients and the success of percutaneous revascularization. However, more extensive studies are needed.

Endovascular Treatment for Fungal Internal Carotid Artery Aneurysm.

Fungal cerebral aneurysms, particularly those resulting from direct invasion by fungal sinusitis, are rare and often fatal when involving the cavernous segment of the internal carotid artery (ICA). We present a case of a ruptured fungal ICA aneurysm caused by sinusitis, successfully treated with parent artery occlusion (PAO). In this case, an 80-year-old woman presented with right ptosis, facial pain, and cranial nerve III, IV, and VI palsies.

In our study, we performed both computed tomographic angiography (CTA) and digital substraction angiography (DSA) collateral artery flow scoring in anterior system acute stroke patients who underwent mechanical thrombectomy (MT) within the first 16 hours. The study aimed to evaluate the consistency of both scoring methods and their relationship with the 90-day clinical outcomes of the patients. From January to December 2022, the files of patients with middle cerebral artery occlusion who underwent MT and were followed up at a stroke center were retrospectively reviewed.

Purpose: We retrospectively analyzed the effect of coil type on the number of coils used and the procedure time in pre-Fontan coil embolization of collateral arteries.
Material And Methods: Twelve patients with congenital heart disease underwent coil embolization before Fontan surgery between 2010 and 2021. They were divided into 2 groups.

Background: Collateral circulation influences clinical outcomes in patients with acute ischemic stroke due to anterior circulation large-vessel occlusion (LVO). While both arterial and venous collateral assessments on single-phase computed tomography angiography (CTA) have prognostic value, they have traditionally been evaluated independently.
Purpose: We developed the CTA Collateral Impairment Score (CCIS), a composite measure incorporating arterial (Tan) and venous (Cortical Venous Opacification Score (COVES)) scores, and investigated its association with 90-day functional outcomes.
