• arterial
  • Tourniquet equivalents In the same way that external compression tourniquets reduce or eliminate arterial blood flow, aortic cross clamping has the same effect. (wikipedia.org)
  • Schaper summarizes the status-2009 knowledge of coronary collateral transformation in a recent review: "Following an arterial occlusion outward remodeling of pre-existent inter-connecting arterioles occurs by proliferation of vascular smooth muscle and endothelial cells. (wikipedia.org)
  • arch
  • Features that make stent placement more difficult include significant aortic arch tortuosity, thrombus containing lesions, occluded carotid artery, heavily calcified vessels, symptomatic patients and very tortuous and twisting vessels. (wikipedia.org)
  • myocardial
  • After balloon removal there is also a risk of 'embolic shower' from micro clots that have formed on the surface of the balloon, and can lead to peripheral thrombosis, myocardial ischemia, hemodynamic decompensation, and late pseudoaneurysm. (wikipedia.org)
  • perfusion
  • Hypertonic/hyperoncotic fluids may reduce overall fluid requirements and tissue edema, improve perfusion and reduce the incidence of paraplegia associated with aortic cross-clamping and subsequent reperfusion. (medicalexpress.net.br)
  • clamp
  • Following this the East Carolina University group performed the first video-assisted mitral valve repair through a mini thoracotomy, using video-direction, a transthoracic aortic clamp, and retrograde cardioplegia [ 9 ]. (hindawi.com)
  • dilation
  • A number of other steps may or may not be performed, including the use of a cerebral protection device, pre- or post-stent balloon dilation and cerebral angiography. (wikipedia.org)
  • occlude
  • The balloon (102) is preferably filled with a partitioned resilient material (104) to permit varying diameters of the balloon and occlude body passageways having varying diameters and curvatures. (google.de)
  • This CO2 balloon system was tested on model aortas with inline fluid flow and pressure monitoring to determine the maximum pressure the balloons could occlude. (uwo.ca)
  • vascular
  • Mechanical failure of the balloon itself is also a risk which entails vascular surgery to remove under that circumstance. (wikipedia.org)
  • monocytes and polycytes migrate to the vascular wall, which has, as a result of the occlusion, become permeable to the blood's cellular components. (wikipedia.org)
  • acute
  • Urgent endoscopy is often used to diagnose and sometimes treat acute upper gastrointestinal syndromes (hemorrhage, toxic ingestion, and occlusion). (readbyqxmd.com)
  • device
  • The device and the balloons were then developed for commercial use between 1967 and 1969 heart surgery by William Rassman, M.D. at Cornell Medical Center and were manufactured by Datascope Corporation in 1969. (wikipedia.org)
  • blood flow
  • HAD offered only minor advantages over NaHCO 3 with respect to blood flow and antioxidant status of spinal cord and muscle following this period of aortic cross-clamping and reperfusion. (medicalexpress.net.br)
  • heart
  • aortic root pressure measurement and venting and clearing of the heart and aortic root. (google.com)
  • If one of the heart valves is affected, this may cause dysfunction, such as mitral regurgitation in the case of left-sided coronary occlusion that disrupts the blood supply of the papillary muscles. (wikipedia.org)
  • wherein
  • 8. The method as specified in claim 1 wherein said balloon further comprises a flexible outer shell disposed about said resilient material. (google.de)
  • recent
  • Most observers agree that a 90% occlusion is necessary to bring about transformation in the absence of other factors, though a recent article suggests that they may appear as a result of coronary spasm in the absence of total occlusion (see below). (wikipedia.org)
