The functional significance of coronary collateral flow from a nonobstructed supply artery was studied in 121 patients with severe (>80%) single-vessel disease, 64 with and 57 without Q wave infarction. All patients underwent exercise thallium imaging and coronary angiography. On angiography, collateral flow was present in 85% of 74 occluded arteries compared with only 17% of 47 arteries with s...

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 paper proposes a model of booms and busts in housing and non-housing consumption driven by the interplay between relatively low interest rates and an expansion of credit, triggered by further decline in interest rates and relaxing collateral requirements. When credit becomes available, households would like to borrow in order to frontload consumption, and this increases demand for housing ...

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...
