Improving culprit artery identification with intraprocedural cone-beam CT aortography and its clinical impact in bronchial artery embolization. To evaluate the impact of intraprocedural cone-beam CT (CBCT) aortography on culprit artery identification and clinical outcomes in patients undergoing bronchial artery embolization (BAE). Two hundred eighty-two patients with 317 BAE procedures were retrospectively reviewed. Patients who underwent preprocedural chest CT angiography (CTA) without intraprocedural CBCT aortography were categorized as Group A (n = 177). Patients who underwent both preprocedural chest CTA and intraprocedural CBCT aortography were categorized as Group B (n = 105). Whether CBCT can provide improved culprit artery identification and whether this improvement has a clinical impact
Trends in computed tomography aortography and acute aortic syndrome in an emergency department within Aotearoa New Zealand. Acute aortic syndrome (AAS) comprises a triad of life-threatening aortic conditions that are difficult to diagnose because of their non-specific clinical presentations. Contrast-enhanced computed tomography aortography (CTA) has a high sensitivity and specificity
Computed Tomography-Aortography Versus Color-Duplex Ultrasound for Surveillance of Endovascular Abdominal Aortic Aneurysm Repair: A Prospective Multicenter Diagnostic-Accuracy Study (the ESSEA Trial). Background Color-duplex ultrasonography (DUS) could be an alternative to computed tomography-aortography (CTA) in the lifelong surveillance of patients after endovascular aneurysm repair (EVAR
Quantitative aortography for assessing aortic regurgitation after transcatheter aortic valve implantation: results of the multicentre ASSESS-REGURGE Registry. Quantitative aortography using videodensitometry is a valuable tool for quantifying paravalvular regurgitation after TAVI, especially in the minimalist approach - without general anaesthesia. However, retrospective assessment of aortograms showed moderate feasibility of assessment. We sought to determine the prospective feasibility of quantitative aortography after a protocol of acquisition. This was a multicentre registry in Japan, Canada, the Netherlands and Germany including consecutive patients with Heart Team indication to undergo TAVI over a median period of 12 months. Operators performed final aortograms according to a pre-planned
Importance of Contrast Aortography With Lotus Transcatheter Aortic Valve Replacement: A Post Hoc Analysis From the RESPOND Post-Market Study. The aim of this post hoc analysis from the RESPOND (Repositionable Lotus Valve System-Post-Market Evaluation of Real World Clinical Outcomes) post-market study was to assess the final implantation depth on the contrast aortogram after Lotus valve (Boston Scientific, Marlborough, Massachusetts) transcatheter aortic valve replacement (TAVR) and to correlate with permanent pacemaker implantation (PPI) and paravalvular leak (PVL). Contrast aortography allows for the assessment of implantation depth and PVL during and after TAVR. Previous reports suggested an association between final device position and rates of PPI and PVL. The RESPOND study was a prospective
Successful treatment of massive hemothorax with class IV shock using aortography with transcatheter embolization of actively bleeding posterior left intercostal arteries after penetrating left chest trauma: A case for the hybrid OR Hemothorax is a common occurrence after blunt or penetrating injury to the chest. Posterior intercostal vessel hemorrhage as a cause of major intrathoracic bleeding
Effects of anatomical characteristics as factors in abdominal aortic aneurysm rupture: CT aortography analysis. The aim of this study was to analyze the anatomical characteristics of patients with ruptured abdominal aortic aneurysms (AAAs) using computed tomography (CT) aortography in order to determine the risk factors for rupture.We retrospectively reviewed the CT aortography findings and medical records of patients with ruptured AAAs who underwent CT aortography between February 2002 and December 2014. Age, sex, blood pressure at the time of rupture, treatment methods used for the ruptured AAAs, and treatment outcomes were analyzed. Statistical analyses were performed to determine the association between the maximum aneurysm diameter, which is considered the standard predictor
A novel synchronised diastolic injection method to reduce contrast volume during aortography for aortic regurgitation assessment: in vitro experiment of a transcatheter heart valve model. In the minimalist transcatheter aortic valve implantation (TAVI) era, the usage of transoesophageal echocardiography has become restricted. Conversely, aortography has gained clinical ground in quantifying prosthetic valve regurgitation (PVR) during the procedure. In a mock circulation system, we sought to compare the contrast volume required and the accuracy of aortographic videodensitometric PVR assessment using a synchronised diastolic and standard (non-synchronised) injection aortography. Synchronised diastolic injection triggered by the signal stemming from the mock circulation was compared
Tailored Duration of Contrast Material Injection in High-Pitch Computed Tomographic Aortography With a Double-Level Test Bolus Method. To achieve the efficient usage of contrast material (CM) in high-pitch CT aortography, an appropriate duration of the CM injection is crucial. We used a modification of the double-level test bolus method for determination of proper injection duration with the aim of evaluating the image quality of tailored-duration CM injection compared with that of a fixed duration. The institutional review board approved retrospective review of 80 consecutive subjects who had undergone high-pitch 70-kVp CT aortography with a modified double-level test bolus method. The interval between peak enhancement at the aortic root and femoral artery was derived from the time/attenuation

Low-tube-voltage (80 kVp) CT aortography using 320-row volume CT with adaptive iterative reconstruction: lower contrast medium and radiation dose. To evaluate CT aortography at reduced tube voltage and contrast medium dose while maintaining image quality through iterative reconstruction (IR). The Institutional Review Board approved a prospective study of 48 patients who underwent follow-up CT aortography. We performed intra-individual comparisons of arterial phase images using 120 kVp (standard tube voltage) and 80 kVp (low tube voltage). Low-tube-voltage imaging was performed on a 320-detector CT with IR following injection of 40 ml of contrast medium. We assessed aortic attenuation, aortic attenuation gradient, image noise, contrast-to-noise ratio (CNR), volume CT dose index (CTDIvol
