<i >Introduction</i>. Dialysis associated steal syndrome (DASS) constitutes a serious risk for patients undergoing vascular access operations. We aim to assess the measured volume flow using ultrasound in with clinically suspected and determine differences among types of arteriovenous (AV) access. >Methods</i>. Patients permanent hemodialysis without ischemic underwent duplex (US) exams assessment quantitative evidence hemodynamic steal. Volume was proximal feeding artery. >Results</i>. 118...
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,...
Transcarotid artery revascularization (TCAR) has emerged as a safe and effective method for carotid revascularization, offering several key advantages over endarterectomy (CEA) stenting (CAS). Intraoperative transcranial Doppler (TCD) monitoring plays pivotal role in assessing cerebral hemodynamics detecting embolic signals during TCAR at our institution. This review synthesizes the current literature provides guidance TCD throughout various phases of TCAR, from preoperative assessment to...
Not all newly created arteriovenous fistulas (AVFs) successfully mature and develop into a functioning access for hemodialysis. Percutaneous transluminal angioplasty (PTA) balloon-assisted maturation (BAM) have been utilized to either treat flow-limiting stenoses or promote accelerate maturation. We hypothesized that unusable upper arm AVFs can be rescued by conversion functional using the percutaneous placement of stent graft (SG).Clinical data on 12 patients with an early non-usable AVF...
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...
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...
Background: This study aimed to assess intraoperative cerebral hemodynamic responses and embolic events during transcarotid artery revascularization via transcranial Doppler, near-infrared spectroscopy, bispectral index monitoring. Methods: Twelve patients (7 males, 5 females; mean age: 72.8±9.0 years; range, 63 91 years) undergoing with simultaneous monitoring were analyzed in this retrospective between September 2017 December 2019. The flow velocity pulsatility of the middle artery,...
ABSTRACT Introduction It is unclear whether kidney/pancreas (KP) transplantation will prevent the progression of peripheral arterial disease (PAD) in patients with insulin dependent diabetes (IDDM) and end‐stage renal disease. We sought to determine pre‐ posttransplant prevalence symptomatic PAD changes carotid artery intima‐media thickness (IMT) KP recipients. Methods In this single center study, outcomes were compared between recipients without a history PAD. A subset underwent IMT...
