The significance of the extracranial-intracranial anastomoses of carotid system in occlusion of internal carotid artery

Biomolecules & Biomedicine, 2004
The existence of collateral circulation in patients with impaired intracranial circulation was studied. We analysed angiograms of 35 patients of the Neurology Clinic of Clinical Centre in Sarajevo with occlusion of internal carotid artery.

Computational Simulations for Aortic Coarctation: Representative Results From a Sampling of Patients [PDF]

, 2011
Treatments for coarctation of the aorta (CoA) can alleviate blood pressure (BP) gradients(D), but long-term morbidity still exists that can be explained by altered indices of hemodynamics and biomechanics.

The preservation effect of coronary collateral circulation on left ventricular function in chronic total occlusion and its association with the expression of vascular endothelial growth factor A.

Advances in Clinical and Experimental Medicine, 2020
BACKGROUND Patients with coronary chronic total occlusion (CTO) typically have collateralization of the distal vessel, and these collaterals can contribute to the relief of ischemia and anginal symptoms and to the preservation of ventricular function ...

Sex Differences in Collateral Circulation and Outcome After Mechanical Thrombectomy in Acute Ischemic Stroke

Frontiers in Neurology, 2022
BackgroundCollateral circulation is known to lead to smaller infarct volume and better functional outcome after mechanical thrombectomy (MT), but studies examining sex differences in collateral circulation are scarce.

The ratio between cerebral blood flow and Tmax predicts the quality of collaterals in acute ischemic stroke [PDF]

, 2018
Background In acute ischemic stroke the status of collateral circulation is a critical factor in determining outcome. We propose a less invasive alternative to digital subtraction angiography for evaluating collaterals based on dynamic-susceptibility ...

Leukocytes, Collateral Circulation, and Reperfusion in Ischemic Stroke Patients Treated With Mechanical Thrombectomy.

Stroke, 2019
Background and Purpose- Peripheral immune cells are activated after stroke and may in turn influence the fate of ischemic brain tissue, thus exerting a dual role in ischemic stroke.

Predictors and Prognostic Implications of Well-Matured Coronary Collateral Circulation in Patients with a Chronic Total Occlusion (CTO).

International Heart Journal, 2020
The predictors and prognostic implications of well-matured collaterals in those with a chronic total occlusion (CTO) are unknown. We sought to identify the determinants of collateral maturation and to determine its effects on procedural outcomes and ...

Medical therapy, percutaneous coronary intervention and prognosis in patients with chronic total occlusions [PDF]

, 2015
Objective There is little published data reporting outcomes for those found to have a chronic total coronary occlusion (CTO) that is electively treated medically versus those treated by percutaneous coronary intervention (PCI).

Relevance of peripheral inflammation indexes in different collateral circulation for intracranial hemorrhage in acute anterior circulation ischemic stroke patients undergoing endovascular treatment

Journal of Stroke and Cerebrovascular Diseases
Background: Asymptomatic intracranial hemorrhage (aICH) is common after endovascular thrombectomy (EVT). Collateral circulation could modify the association between aICH with functional outcome and we aimed to investigate the impact of systemic ...
