The screening tool for diagnosing lower extremity arterial disease is the assessment of ankle-brachial index (ABI), which widely used in general practice. However, resting ABI can easily produce a false negative result. In light this, our goal was to determine proportion definitive diagnoses (peripheral [PAD] confirmed or refuted) among patients screened practice, and rate cases need further specialized examination necessary, with special attention groups having non-compressible arteries...
Objective This study aimed to report the initial experience with a novel bidirectional double cuff inner branch design for incorporation of renal and mesenteric arteries in patients undergoing fenestrated branched endovascular aortic repair (F/BEVAR). Methods A retrospective review was undertaken F/BEVAR grafts integrating at least one cuffed implanted three tertiary centres between March 2022 June 2023. All consecutive were included. Baseline characteristics, operative follow up data...
The purpose of this proof-of-concept study was to demonstrate the setup and feasibility transcarotid access for remote robotic neurointerventions in a cadaveric model.The interventional procedures were performed fresh-frozen model using an endovascular system angiography imaging system. A prototype remote, robotic-drive with ethernet-based network connectivity audio-video communication used drive remotely. After surgical exposure common carotid artery model, 8-Fr arterial inserted anchored....
Acute aortic catastrophes (AAC), mainly ruptured aneurysms and dissections, lead all other vascular conditions in morbidity mortality, even if intervention occurs. The aim of our study was to give a descriptive overview the demographic pathological characteristics AAC. Between 1994 2013, 80,469 autopsies were performed at Semmelweis University hospitals Budapest. After collecting autopsy reports we able create AAC database upon which conducted analysis. We found 567 cases cause death 120...
Purpose: To illustrate dynamic, time-resolved CTA (d-CTA) imaging technique in characterizing aortic endoleak type/inflow using quantitative parameters and its value providing image guidance for targeted treatment approach. Technique: Dedicated protocol involved acquiring multiple contrast enhanced scans third-generation CT scanner (Somatom Force ® , Siemens Healthineers). Parameters such as scan field of view (FOV), kV, number/timing were customized based on patient’s body-mass-index,...
Our aim was to investigate whether the previously observed higher contrast-to-noise ratio (CNR) and better image quality of Digital Variance Angiography (DVA) - compared Subtraction (DSA) can be used 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 In all patients, both normal (1.2 µGy/frame; 100%) low-dose (0.36 30%) protocols were for acquisition images three...
Abstract Purpose In retrospective clinical studies digital variance angiography (DVA) provided higher contrast-to-noise ratio and better image quality than subtraction (DSA). Our aim was to verify the usefulness benefits of DVA in carbon dioxide (CO 2 )-assisted lower limb interventions. Materials Methods A workstation running software integrated into a Siemens Artis Zee with Pure system, this new processing technology used four patients (3 male, 1 female, age: 76.2 ± 4.2 years) peripheral...
Background: digital variance angiography (DVA) provides higher image quality than subtraction (DSA). This study investigates whether the reserve of DVA allows for radiation dose reduction during lower limb (LLA), and compares performance two algorithms. Methods: this prospective block-randomized controlled enrolled 114 peripheral arterial disease patients undergoing LLA into normal (ND, 1.2 µGy/frame, n = 57) or low-dose (LD, 0.36 groups. DSA images were generated in both groups, DVA1 DVA2...
Our purpose was to study the accuracy of dynamic computed tomography angiography (d-CTA) in characterizing endoleak type, inflow vessels as compared with digital subtraction (DSA) using qualitative and quantitative analysis.Between March 2019 January 2021, all patients who underwent d-CTA imaging after EVAR were retrospectively reviewed. Two blinded independent reviewers qualitatively reviewed DSA images. Quantitative region interest (ROI) analysis performed by measuring time-resolved...
Abstract Background Over the span of last decade, medical research has been increasingly putting greater emphasis on study meteorological parameters due to their connection cardiovascular diseases. The main goal this was explore relationship between fatal aortic catastrophes and changes in atmospheric pressure temperature. Methods We used a Cox process model quantify effects environmental factors sudden deaths resulting from catastrophes. transfer entropy draw conclusion about causal...
In many studies on aortic disease, women are underrepresented. The present study aims to assess sex-specific morphometric differences and gain more insight into endovascular treatment of the ascending aorta (AA) arch.Electrocardiogram-gated cardiac computed tomography scans 116 consecutive patients who were evaluated for transcatheter valve replacement retrospectively reviewed. Measurements AA arch made in multiplanar views, perpendicular semi-automatic centerline. Multiple linear regression...
<i>Objective:</i> To evaluate a novel technology for real time tracking of RF-Identified (RFID) surgical tools (Biotic System) (Fig. 1), providing intraoperative data analytics during simulated cardiovascular procedures. Ineffective asset management in the Operating Room (OR) leads to inefficient utilization resources, contributes prolonged operative times and increased costs. Analysis captured can assist quantifying instrument utilization, procedure flow, performance prevention retained...
Absztrakt Bevezetés: Az érhomograftokat korábbi érrekonstrukció után kialakult graftinfekció vagy saját véna hiányában, végtagmentő érműtétek esetén alkalmazzuk. Többszervi donáció során a thoracalis aortaszegmens, aortabifurcatio, arteria iliaca, femoralis és poplitea, illetve vena saphena magna kerülhet eltávolításra. Célunk, hogy az elvégzett beavatkozások eredményeit elemezve optimalizáljuk homograftok alkalmazását. Módszerek: A betegek anyagát retrospektíven dolgoztuk fel kórházi...
Purpose: The aim of this study is to evaluate the value selective intra-arterial cone-beam computed tomography angiography (CBCTA) relative conventional (CTA) in understanding visceral artery aneurysm (VAA) morphology, and its impact on treatment planning. Materials Methods: Between January 2017 August 2021, all patients who had a diagnosis VAA underwent intraoperative CBCTA imaging were retrospectively reviewed. Impact decisions, optimal C-arm angulations derived from CBCTA, additional...
Abstract Introduction Emergent complex abdominal aortic diseases are challenging to treat. During In-situ laser fenestration (ISLF) branches covered and then restored with in-situ of the stentgraft promising mid-term results1. The aim this study was examine our outcome ISLF in visceral pathology. Method Retrospective multicenter on consecutive cases stent-grafts 2018-2023 three centers. Technical success defined as a successful vascularization bridging stent without any type 3 endoleak....
Abstract Introduction Structural defects during fenestrated endovascular aortic repair (FEVAR) can be difficult to identify intraoperatively. This study aims assess the potential value of routine intraoperative completion cone-beam computed tomography (CBCT) FEVAR. Method A retrospective review all consecutive FEVARs in a 10-year period was performed our center. Patients with plain CBCT and postoperative CTA were selected. Endpoints included adjunctive procedures (IAP) early secondary...
Purpose: Direct percutaneous access to the carotid artery (diPerCa) during endovascular aortic arch repair (EVAAR) can potentially present a minimally invasive with lesser local adverse events. Techniques: A retrospective review of consecutive EVAAR between January 2018 and 2024, in tertiary referral center, was performed identify cases, which diPerCa used. Patients who were planned for no previous intervention included. standardized technique employed where an ultrasound-guided retrograde...
