Function of the coronary collateral circulation during the course of a single abrupt coronary occlusion was evaluated in awake dogs instrumented over the long term. Studies were performed approximately 2 weeks after collateral development had been stimulated in the dogs by partial stenosis of the proximal left circumflex coronary artery. The pressure drop from the central aorta to the distal ci...

Collateral ligament injury can be a cause of ACL graft failure. These ligament injuries must be addressed at revision surgery in order to prevent failure of the revision surgery. In malalignment with associated collateral ligament injury, osteotomy may be the preferred choice to manage the collateral ligament laxity. This outline will describe techniques for managing collateral ligament injury ...

This study investigates how the use of collateral affects incentives for borrowers and lenders and the resulting loan pricing relationship. With data from the UK Survey of Small and Medium-Sized Enterprises 2008, a simultaneous equation approach reveals that high quality borrowers choose contracts with more collateral and lower interest rates, which suggests that collateral acts as an incentive...

A patient with an umbilical hernia presenting with collateral veins in the abdominal wall and umbilicus is a case that every hernia surgeon has to deal with occasionally. Several underlying diseases have been described to provoke collateral veins in the abdominal wall. However, the treatment strategy should be uniform. We herein report a case of a successful laparoscopic umbilical hernia repair...

RATIONALE Collaterals are arteriole-to-arteriole anastomoses that connect adjacent arterial trees. They lessen ischemic tissue injury by serving as endogenous bypass vessels when the trunk of 1 tree becomes narrowed by vascular disease. The number and diameter ("extent") of native (preexisting) collaterals, plus their amount of lumen enlargement (growth/remodeling) in occlusive disease, show re...

BACKGROUND AND PURPOSE Good CTA collaterals independently predict good outcome in acute ischemic stroke. Our aim was to evaluate the role of collateral circulation and its added benefit over CTP-derived total ischemic volume as a predictor of baseline NIHSS score, total ischemic volume, hemorrhagic transformation, final infarct size, and a modified Rankin Scale score >2. MATERIALS AND METHODS...

BACKGROUND The platelet products thromboxane A2 and serotonin have been shown to cause constriction of well-developed coronary collateral vessels. This study was performed to determine whether intravascular platelet activation produced with platelet activating factor (PAF) can cause a decrease in coronary collateral blood flow. METHODS AND RESULTS Collateral vessel growth was induced by embol...
