• 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)
  • 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)
  • 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)
  • subsequent
  • 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)
  • 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)
  • syndrome
  • Some examples include: Twin-twin transfusion syndrome - laser ablation of vessels Fetal bladder obstructions Aortic or pulmonary valvuloplasty - opening the aortic or pulmonary fetal heart valves to allow blood flow Atrial septostomy - opening the inter-atrial septum of the fetal heart to allow unrestricted blood flow between the atria Congenital diaphragmatic hernia - balloon tracheal occlusion Image-guided surgery Fetoscopy Peiró JL, Carreras E, Guillén G, et al. (wikipedia.org)
  • hemodynamic
  • 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)
  • 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)
  • 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)
  • 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)
  • heart
  • 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)
  • delivery
  • The inflated balloon (56) isolates the two delivery openings (72,82) from one another to facilitate use of an extracorporeal circuit. (google.de)
