Collateral blood vessels in acute ischemic stroke: a physiological window to predict future outcomes

Arquivos de Neuro-Psiquiatria, 2016
Collateral circulation is a physiologic pathway that protects the brain against ischemic injury and can potentially bypass the effect of a blocked artery, thereby influencing ischemic lesion size and growth.

Baseline Characteristics Associated with Good Collateral Status Using Hypoperfusion Index as an Outcome

Tomography, 2022
Up to 30% of ischemic stroke cases are due to large vessel occlusion (LVO), causing significant morbidity. Studies have shown that the collateral circulation of patients with acute ischemic stroke (AIS) secondary to LVO can predict their clinical and ...

Comparison between modified Allen’s test and Barbeau test for the assessment of hands’ collateral circulation before arterial puncture among critically ill patients

International Journal of Africa Nursing Sciences, 2021
Background: Continuous monitoring of critically ill patients requires an important procedure as arterial puncture. The first site of choice for arterial puncture is radial artery.

The pathophysiology of the collateral circulation (arteriogenesis) [PDF]

The Journal of Pathology, 2000
Since the mid 1980s a new strategy is coming from bench to bedside termed angiogenesis. This process involves sprouting of capillaries and finally results in newly developed microvessels which belong to the capillary level. Importantly these newly formed capillary tubes lack vascular smooth muscle cells, they are not surrounded by mural cells and are ...

Collateral Circulation and Rabep2 Polymorphisms in Large Artery Occlusion: Impacts on Short‐ and Long‐Term Prognosis

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Intracranial anterior circulation large artery occlusion (AC‐LAO) is a predominant cause of ischemic stroke. Although collateral circulation plays a critical role in stroke outcomes, the genetic and environmental factors affecting collateral ...

The association between single-point insulin sensitivity estimator and high-sensitivity C-reactive protein with collateral circulation in coronary chronic total occlusion

Frontiers in Endocrinology
BackgroundThe single-point insulin sensitivity estimator (SPISE) is a novel metric used to assess insulin resistance. However, its association with collateral circulation impairment in patients with chronic total occlusion (CTO) remains unclear.

The coronary collateral circulation revisited [PDF]

Netherlands Heart Journal, 2013
The coronary collateral circulation constitutes a vascular network that forms bridges between adjacent arteries. In response to obstructive coronary artery disease (CAD) due to atherosclerotic plaque progression, these bridging vessels enlarge by a complex interplay of physical forces along with molecular and cellular players.
