• embolization
  • In view of the histologic findings, the regional distribution of the rash, and the temporal relationship to the procedure, this reaction is compatible with panniculitis secondary to particle embolization of the drug-eluting balloon coating, including paclitaxel and urea components. (onlinejacc.org)
  • Embolization involves the selective occlusion of blood vessels by purposely introducing emboli, in other words deliberately blocking a blood vessel. (wikipedia.org)
  • arteries
  • In the latter group, the lumen was filled with bright speckled or low echogenic material, although angiography revealed excellent coronary dilation in all these arteries. (onlinejacc.org)
  • Arteries with a lumen filled with bright speckled or low echogenic material frequently develop abrupt occlusion. (onlinejacc.org)
  • By the late 1960s, Melvin Judkins had begun work on creating catheters that were specially shaped to reach the coronary arteries to perform selective coronary angiography. (wikipedia.org)
  • Microvascular dysfunction: The theory gaining the most traction is that there is dysfunction of the coronary arteries at the level where they are no longer visible by coronary angiography. (wikipedia.org)
  • It may also involve transcranial doppler exam of arteries to the brain Echocardiography, sometimes involving more specialized techniques such as Transesophageal echocardiography (TEE) or myocardial contrast echocardiography (MCE) to diagnose myocardial infarction Arteriography of the affected extremity or organ Digital subtraction angiography is useful in individuals where administration of radiopaque contrast material must be kept to a minimum. (wikipedia.org)
  • aortic
  • The purposes of this study were to evaluate the clinical, hemodynamic, and angiographic changes after stent-supported reconstruction of the aortic bifurcation with the kissing balloon technique and to assess the long-term results of this procedure. (ahajournals.org)
  • Temporary aortic occlusion may be performed prior to definitive hemostasis for trunk injury accompanied by hemorrhagic shock in which bleeding control is difficult. (pubmedcentralcanada.ca)
  • Aortic occlusion was conventionally performed by cross-clamping the aorta after resuscitative thoracotomy. (pubmedcentralcanada.ca)
  • Therefore, cross-clamping after thoracotomy has been replaced with the aortic occlusion technique because of the latter's greater efficacy and feasibility. (pubmedcentralcanada.ca)
  • coils
  • The coils replace the balloons Between the end of the '80s and the beginning of the '90s, INR was suddenly revolutioned after the work of two italian physicians: Cesare Gianturco and Guido Guglielmi. (wikipedia.org)
  • Indirect CCF may be treated by occlusion of the affected cavernous sinus with coils, liquid agents or a combination of both. (wikipedia.org)
  • collateral
  • We conducted a preoperative angiography and a BTO of the right ICA to evaluate collateral flows. (scirp.org)
  • 2) Checking the development of collateral veins/ angiography under balloon occlusion of the GR shunt reveals many collateral veins. (ynjr.net)
  • Contrast X- ray examination of the shunt is performed under balloon occlusion to grade the development of collateral veins and the gastric varices. (ynjr.net)
  • The grade 1 and 2 collateral veins rarely need occlusion, but grade 3 and higher veins require occlusion. (ynjr.net)
  • For grade 2 to 4, the downgrading technique is performed once, and if this is successful, less or no occlusion of the collateral veins is required. (ynjr.net)
  • 10 One in 4 of these individuals was found to have sufficient collateral support to prevent ischemia on sudden balloon occlusion. (ahajournals.org)
  • In addition to evaluating the symptoms described above, angiography can distinguish between cases caused by arteriosclerosis obliterans (displaying abnormalities in other vessels and collateral circulations) from those caused by emboli. (wikipedia.org)
  • However, it takes time for sufficient collateral circulation to develop, making affected areas more vulnerable for sudden occlusion by embolisation than for e.g. gradual occlusion as in atherosclerosis. (wikipedia.org)
  • ischemia
  • Following the balloon inflation, the LF component of RR interval began to increase after the onset of myocardial ischemia, peaked at about 80 s, and then declined in the late phase of inflation. (onlinejacc.org)
  • The patients with no LF augmentation had little evidence of myocardial ischemia as reflected by changes in ST segment and LV systolic function during coronary occlusion. (onlinejacc.org)
  • They are rarely if ever observed during angiography in the absence of severe ischemia (vessels less than 200 micrometers are not visible, generally), and only coronary stenosis, anemia, and exercise have experimentally been shown to cause transformation. (wikipedia.org)
  • aneurysms
  • The remodeling technique of balloon-assisted Guglielmi detachable coil placement in wide-necked aneurysms: experience at the University of Illinois at Chicago. (springer.com)
  • Safety and efficacy of adjunctive balloon remodeling during endovascular treatment of intracranial aneurysms: a literature review. (springer.com)
  • Complications such as aneurysms, dissections, or occlusion of othe renal artery have been associated with renal artery FMD. (wikipedia.org)
  • heparin
  • Before the angiography, a bolus heparin of 5000 units was administered intravenously and the activated clotting time reached 282 sec. (scirp.org)
  • chronic total
  • Patients with high-grade lesions or chronic total occlusions (CTOs) (duration ≥4 weeks, Thrombolysis In Myocardial Infarction grade 0 or 1 flow) and Canadian Cardiovascular Society class 2 or 3 exertional angina were eligible. (ahajournals.org)
  • There are 800,000 Chronic Total Occlusions (CTO) per year in the USA. (wikipedia.org)
  • Implantation
  • Methods and Results -In 48 patients with obstructions of the aortoiliac segment, primary stent implantation was performed with the "kissing balloon technique. (ahajournals.org)
  • CTEPH
  • Both V/Q scanning and modern multidetector CT angiography (CTPA) may be accurate methods for the detection of CTEPH, with excellent diagnostic efficacy in expert hands (sensitivity, specificity, and accuracy of 100%, 93.7%, and 96.5% for V/Q and 96.1%, 95.2%, and 95.6% for CTPA). (wikipedia.org)
  • transcatheter
  • B- RTO (balloon- occluded retrograde transvenous obliteration) has developed in Japan since 1996 as a transcatheter treatment for large gastric varices. (ynjr.net)
  • typically
  • Evaluation of individuals with Takotsubo cardiomyopathy typically includes a coronary angiogram to rule out occlusion of the left anterior descending artery, which will not reveal any significant blockages that would cause the left ventricular dysfunction. (wikipedia.org)
  • Thrombectomy
  • In the legs, below the inguinal ligament, percutaneous aspiration thrombectomy is a rapid and effective way of removing thromboembolic occlusions. (wikipedia.org)
  • In the arms, balloon thrombectomy is an effective treatment for thromboemboli as well. (wikipedia.org)
  • total
  • We administered ioxaglic acid (Hexabrix, Guerbet Japan, Tokyo, Japan) at a rate of 3 mL/s and total amount of 5 mL for the right ICA angiography ( Figure 1(a) , Figure 1(b) ). (scirp.org)
  • 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)
