BACKGROUND Arteriogenesis refers to the development of collateral conductance arteries and is orchestrated by circulating monocytes, which invade growing collateral arteries and act as suppliers of cytokines and growth factors. CD44 glycoproteins are involved in leukocyte extravasation but also in the regulation of growth factor activation, stability, and signaling. Here, we explored the role o...

Background—Arteriogenesis refers to the development of collateral conductance arteries and is orchestrated by circulating monocytes, which invade growing collateral arteries and act as suppliers of cytokines and growth factors. CD44 glycoproteins are involved in leukocyte extravasation but also in the regulation of growth factor activation, stability, and signaling. Here, we explored the role o...

The mouse ischemic hindlimb model is used widely for studying collateral artery growth (i.e., arteriogenesis) in response to increased shear stress. Nonetheless, precise measurements of regional shear stress changes along individual collateral arteries are lacking. Our goal is to develop and verify trans-illumination laser speckle flowmetry (LSF) for this purpose. Studies of defibrinated bovine...

An unusual unilateral variation in the branching pattern of axillary artery was observed in a 60 year old female embalmed cadaver. The axillary artery had only two branches arising from its proximal (first) part and no branches from its remaining distal (second & third) parts. The branches are superior thoracic (usual) and another large collateral (unusual) branch. This collateral branch is the...

OBJECTIVE The objective of this study was to evaluate the efficacy of hemostasis with patency in avoiding radial artery occlusion after transradial catheterization. BACKGROUND Radial artery occlusion is an infrequent but discouraging complication of transradial access. It is related to factors such as sheath to artery ratio and is less common in patients receiving heparin. Despite being clini...

Arteriosclerotic vascular disease is the most common cause of death and a major cause of disability in the developed world. Adverse outcomes of arteriosclerotic vascular disease are related to consequences of tissue ischemia and necrosis affecting the heart, brain, limbs, and other organs. Collateral artery growth or arteriogenesis occurs naturally and can help restore perfusion to ischemic tis...

Background. Although aspirin exerts beneficial antiplatelet activity in patients with coronary artery disease, cyclooxygenase blockade produced by aspirin causes a potentially deleterious effect by interrupting endothelial production of prostacyclin. Collateral vessels that develop in response to coronary occlusion display prominent endothelial cell proliferation and undergo vasoconstriction in...

Brachial artery Bilateral trifurcation Radial recurrent artery The variations in the arterial pattern specially in the extremities are common. The trifurcation of brachial artery into radial, ulnar and either common interosseous or median artery are found commonly, but radial recurrent artery as a third branch is very rarely reported. Here we are reporting a rare case of bilateral trifurcation ...

CONTEXT Coeliac artery stenosis is a condition affecting a minority of patients undergoing pancreaticoduodenectomy. In such cases, the development of collateral pathways through the blood supply of the pancreatic head provides challenges for surgical management. CASE REPORT We report a case of coeliac artery stenosis in a patient undergoing pancreaticoduodenectomy. The main blood supply for t...

OBJECTIVE This study was aimed to evaluate relationship between hyperintense vessels (HV) on fluid-attenuated inversion recovery (FLAIR) and artery steno-occlusion related intracerebral collaterals. MATERIALS AND METHODS A total of 233 patients with 260 atherosclerotic lesions in the M1 segment of the middle cerebral artery (MCA) were examined with FLAIR and digital subtraction angiography (D...
