Direct quantitative assessment of the peripheral artery collateral circulation in patients undergoing angiography.
BACKGROUND Despite the fact that numerous studies have pursued the strategy of improving collateral function in patients with peripheral artery disease, there is currently no method available to quantify collateral arterial function of the lower limb. METHODS AND RESULTS Pressure-derived collateral flow index (CFIp, calculated as (occlusive pressure-central venous pressure)/(aortic pressure-c...
متن کاملDirect Quantitative Assessment of the Peripheral Artery Collateral Circulation in Patients Undergoing Angiography
Peripheral artery disease of the lower extremities is a common disease and present in 15% to 20% of persons older than 65 years. Endovascular or surgical therapy fails or is not applicable in approximately one fourth of patients who would need revascularization therapies, which makes alternative approaches such as arteriogenesis (the positive remodeling of preformed collateral arterioles) neces...
متن کاملCombining the Modified Allen’s Test and Pulse Oximetry for Evaluating Ulnar Collateral Circulation to the Hand for Radial Artery Catheterization of the ED Patient
Radial artery catheterization for the purpose of continuous blood pressure monitoring and frequent blood gas sampling is regularly performed in the emergency department (ED) and in the intensive care unit (ICU). In the operating room, anesthesiologists generally have the benefit of a conscious and cooperative patient, and the modified Allen’s test can be performed before catheterization of the ...
متن کاملHand circulation after radial artery harvest for coronary artery bypass grafting.
Despite wide spread use of the radial artery (RA) graft for coronary artery bypass grafting, the change of hand circulation after RA harvest has not been fully clarified. Severe hand ischemia such as resting pain or gangrene is a rare complication and has been reported in 4 patients. These cases resulted from occlusive artery disease in forearm, which should be carefully explored before RA harv...
