Background: digital variance angiography (DVA) provides higher image quality than digital subtraction angiography (DSA). This study investigates whether the quality reserve of DVA allows for radiation dose reduction during lower limb angiography (LLA), and compares the performance of two DVA algorithms.
Methods: this prospective block-randomized controlled study enrolled 114 peripheral arterial disease patients undergoing LLA into normal dose (ND, 1.

We compared the diagnostic performance of non-contrast Quiescent-interval single-shot magnetic resonance angiography (QISS MRA) and carbon-dioxide digital subtraction angiography (CO2 DSA) in chronic lower extremity PAD patients. A 19-segment lower extremity arterial model was used to assess the degree of stenosis (none, <50%, 50−70%, >70%) and the image quality (5-point Likert scale: 1-non-diagnostic, 5-excellent image quality).

The only urgent endovascular alternative to high-risk open surgery in the treatment of postdissection aneurysms is branched endovascular aortic repair (BEVAR), which is extremely difficult due to the intimal membrane in the aorta lumen and the compressed true lumen. In this case report, we present the first application of BEVAR for aortic dissection in Hungary.

Bevezetés: Az akut alsó végtagi ischaemia nagy klinikai jelentőségét gyakori előfordulása és súlyos szövődményei (amputáció, halálozás) okozzák. A műtéti megoldás mellett a katéterrel végzett thrombolysis jelent terápiás lehetőséget, használata azonban nem terjedt el széles körben hazánkban.
View Article and Find Full Text PDFOur aim was to investigate whether the previously observed higher contrast-to-noise ratio (CNR) and better image quality of Digital Variance Angiography (DVA) - compared to Digital Subtraction Angiography (DSA) - can be used to reduce radiation exposure in lower limb X-ray angiography. This prospective study enrolled 30 peripheral artery disease patients (mean ± SD age 70 ± 8 years) undergoing diagnostic angiography. In all patients, both normal (1.

If the vertebral artery can be sacrificed, embolization with coiling, liquid injection, or parent artery exclusion can be done. We hereby present a case of a 74-year-old male patient presenting with an asymptomatic atherosclerotic giant extracranial vertebral artery aneurysm in the V1 segment of the vertebral artery, successfully treated with balloon expandable stent-graft deployment.

Background: Little is known about the optimal vascular access for PULA interventions, despite the well-known technical complexity of these procedures.
Methods: We performed the retrospective analysis of consecutive patients treated for symptomatic steno-occlusive disease of the proximal upper limb arteries between January 2015 and December 2019 in three high-volume centers.
Background: Mycotic aortic pseudoaneurysm is a rare complication after heart transplantation (HTX) with remarkable mortality. Intrathoracic infection is a well-documented predisposing factor for this disease. Staphylococcus aureus, Pseudomonas aeruginosa or Candida species are commonly isolated from resected specimens of the pseudoaneurysms.

Patients And Methods: Between 1st of June 2013 and 31st of July 2016, we performed 130 TACE procedures in 64 patients in the Borsod University Teaching Hospital at Miskolc.
