TAA 4. Four-Dimensional Computed Tomography Angiography for Unclassified Endoleaks After Thoracic Endovascular Aortic Repair
The objective of this study was to assess the feasibility and safety of four-dimensional computed tomography angiography (4D-CTA) for unclassified endoleaks by conventional computed tomography angiography (C-CTA) in patients after thoracic endovascular aortic repair.
rich GS Abstract OBJECTIVE: To investigate the association between psoas muscle area (PMA) and density (PMD) with survival and quality of life (QoL) after fenestrated-branched endovascular aortic repair (F-BEVAR). METHODS: The study included 244 consecutive patients enrolled in a prospective study to investigate outcomes of F-BEVAR. Pre-operative computed tomography angiography was used to measure PMA (cm2) and PMD (Hounsfield unit [HU]) at the L3 level. Lean PMA (LPMA) was calculated (PMA × PMD). Patients were divided into two groups using the LPMA cut off point based on a Cox hazard model. G...
Abstract OBJECTIVES: With a focus on renal function, the goal of this multicentre study was to assess peri-operative complications and late mortality of open surgical repair (OSR) of juxtarenal abdominal aortic aneurysms (JRAAA). METHODS: From February 2005 to December 2015, 315 consecutive patients undergoing elective OSR of a JRAAA in five French academic centres were evaluated retrospectively. The definition of JRAAA was an aortic aneurysm extending up to but not involving the renal arteries, i.e., a short neck
CONCLUSION: Pre-EVAR planning should focus on identification of risk factors for kinking. Adjunctive stenting is an effective prophylaxis for selected high risk limbs, yet intra-operative identification remains problematic. Also, it is noteworthy that most limb occlusions occur in the first year after EVAR, emphasising the importance of careful early follow up of high risk patients.

Rationale: Penetrating aorta ulcer (PAU) with isolated left vertebral artery (ILVA) is a rare condition, accounting for no more than 1% of all kinds of aorta diseases. And traditional treatment was open surgery with total arch replacement by elephant trunk. Here, we report a case of PAU combined with ILVA managed by thoracic endovascular aortic repair (TEVAR) technique. Patient concerns: A 65-year-old male with chronic hypertension and Nicotine abuse underwent intermittent back pain for 2 years and aggravated a bit for 1 week. Diagnoses: Preoperative computed tomography angiogram (CTA) indicated PAU combined with I...
Conclusions Virtual noncontrast images based on venous-phase scans appear to be a more accurate representation of TNC scans than VNC images based on arterial-phase scans.
AbstractCoronary artery anomalies (CAA) are vanishingly rare, affecting less than 1% of the general population. While the majority of anomalies do not cause significant symptoms; those that do, have devastating outcomes on the patient. Seventeen percent of deaths from exercise is attributed to CAA, and over half of these present as sudden death making CAA the second most common cause of sudden cardiac death in individuals. Computed tomography is generally regarded as the first ‐line investigation due to its superior ability to delineate the course of the coronary vessels and the surrounding structures, while intravascula...
We report a rare case of 4 cm true aneurysm of left axillary artery in a 3-year-old girl. Computed tomography angiography confirmed the diagnosis. Open surgical repair with resection and primary end-to-end anastomosis was performed. The patient did not have any complication after 1-year follow-up. Axillary artery aneurysm i s extremely rare in pediatric population. Previous reports of this rare entity are discussed comprehensively.
ConclusionThe accuracy and speed of the proposed method allow for use in an intraoperative setting of deformation correction for EVAR.
A 73-year-old woman with a history of a 6-cm juxtarenal abdominal aortic aneurysm who underwent a fenestrated endovascular aortic repair using the Zenith fenestrated endovascular (ZFEN) device (Cook Medical, Bloomington, Ind) presented with a type IA endoleak found on routine surveillance computed tomography angiography (CTA). The previously placed ZFEN device included a scallop for the superior mesenteric artery (SMA) and bilateral stented fenestrations to the renal arteries.
Presence of gas is a frequent finding on early postoperative computed tomography angiography (CTA) after endovascular aortic aneurysm repair (EVAR) with unclear clinical relevance. The aim of this study was to examine and compare the presence of gas within the aneurysm sac following EVAR on early postoperative CTA after the use of carbon-dioxide (CO2) flushing technique with saline flushing alone.
