• distal
  • The flow pattern was characterized by high-velocity, turbulent, slightly pulsating, monophasic venous flow that was not influenced by respiration ( Figure , B). When interpreted together, these spectral Doppler findings indicate the presence of a pseudoaneurysm in communication with an arteriovenous fistula emptying into the distal portion of the common femoral vein.

  • The purpose of this study is to analyze and identify pre-, intra-, and post- operative parameters that predict Steal-Syndrome with distal malperfusion after Arterio-Venous Fistulas (AVF) as primary endpoint. (clinicaltrials.gov)
  • ligation
  • After consideration at multidisciplinary review, the patient was referred for surgical ligation of the fistula in December 2008. (ahajournals.org)
  • bruit
  • CCF symptoms include bruit (a humming sound within the skull due to high blood flow through the arteriovenous fistula), progressive visual loss, and pulsatile proptosis or progressive bulging of the eye due to dilatation of the veins draining the eye. (wikipedia.org)
  • One can also listen through a stethoscope for the sound of the blood "whooshing" through the fistula, a sound called bruit. (wikipedia.org)
  • classically
  • We examine the case of a female evaluated in the emergency department with a vertebral AV fistula presenting classically as pulsatile tinnitus and later successfully treated with standard endovascular techniques. (hindawi.com)
  • patients
  • Patients will be eligible if they are 19 years of age or greater and have placement of an arteriovenous fistula planned witin 30 days. (clinicaltrials.gov)
  • However, in patients who develop symptoms indicating disease progression or the pseudoaneurysm/arteriovenous fistula fails to undergo spontaneous thrombosis within 3 months, other treatment options, including surgery or interventional therapy with stent graft of the feeding artery, must be considered.

  • Letter: Swelling of arm in patients with arteriovenous fistula. (bmj.com)
  • Eleven patients have so far been dialysed for a total of 80 fistula months. (bmj.com)
  • The spontaneous dural cavernous fistula which is more common usually results from a degenerative process in older patients with systemic hypertension and atherosclerosis. (wikipedia.org)
  • Cimino recognized that these fistulas did not cause the patients harm and were easy places to get repeated blood samples. (wikipedia.org)
  • Patients may have multiple accesses, usually because an AV fistula or graft is maturing and a catheter is still being used. (wikipedia.org)
  • Cimino
  • Before the Cimino fistula was invented, access was through a Scribner shunt, which consisted of a Teflon tube with a needle at each end. (wikipedia.org)
  • Frustrated by this limitation, James E. Cimino recalled his days as a phlebotomist (blood drawer) at New York City's Bellevue Hospital in the 1950s when Korean War veterans showed up with fistulas caused by trauma. (wikipedia.org)
  • veins
  • There is new information that links vitamin D to the function of our veins and arteries, which are used in the creation of an arteriovenous fistulae. (clinicaltrials.gov)
  • If the fistula is near the surface, a mass can be felt, and the affected area is usually swollen and warm with distended, often pulsating superficial veins. (merckmanuals.com)
  • placement
  • Placement in the groin is usually done when options in the arm and hands are not available due to anatomy or the failure of fistulas previously created in the arms/hands. (wikipedia.org)
  • Procedure
  • In addition, Demographic parameters and patient comorbidities will be acquired and procedure specific parameters (e.g. location of the fistula) will be documented. (clinicaltrials.gov)
  • occur
  • Direct fistulas occur when the Internal Carotid artery (ICA) itself fistulizes into the Cavernous sinus whereas indirect is when a branch of the ICA or External Carotid artery (ECA) communicates with the cavernous sinus. (wikipedia.org)
