Prospective nonrandomized study to evaluate cone beam computed tomography for technical assessment of standard and complex endovascular aortic repair.

Objective: The objective of this study was to analyze the utility of cone beam computed tomography (CBCT) for technical assessment of standard and complex endovascular aneurysm repair (EVAR).

Methods: Data of consecutive patients who underwent standard or complex EVAR in 2016 and 2017 at our institution were entered into a prospective database and analyzed retrospectively. There were 154 patients (126 male; mean age, 74 ± 8 years) enrolled in a prospective study between 2016 and 2017.

Preloaded Catheters and Guide-Wire Systems to Facilitate Catheterization During Fenestrated and Branched Endovascular Aortic Repair.

Objective: The aim of this study was to review the clinical outcomes for patients treated for pararenal (PRA) and thoracoabdominal aortic aneurysms (TAAAs) by fenestrated-branched endovascular aortic repair (F-BEVAR) using preloaded systems (PLS).

Methods: We reviewed clinical data of 83 patients (64 male, mean age 75 ± 7 years) enrolled in a prospective study to investigate F-BEVAR. All patients had PLS, which included two catheters or two through-and-through guide wires with 12-Fr trans-brachial sheaths positioned in the descending thoracic aorta.

Comparison of Perioperative Outcomes of Patients with Iliac Aneurysms Treated by Open Surgery or Endovascular Repair with Iliac Branch Endoprosthesis.

Background: Treatment of common and internal iliac aneurysms is usually done by open surgery. A novel iliac branch endoprosthesis (IBE) is commercially available with encouraging initial results. Our objective is to compare perioperative outcomes of patients with iliac aneurysms treated by open surgery (OS) versus endovascular repair with IBE.

Outcomes of upper extremity access during fenestrated-branched endovascular aortic repair.

Objective: Upper extremity (UE) access is frequently used during fenestrated-branched endovascular aortic repair (F-BEVAR) to facilitate catheterization of downgoing vessels. Limitations include risk of cerebral embolization and of UE arterial or peripheral nerve injury. The aim of this study was to assess outcomes of F-BEVAR using UE access.

Outcomes of an iliac branch endoprosthesis using an "up-and-over" technique for endovascular repair of failed bifurcated grafts.

Objective: Type IB endoleak after endovascular aneurysm repair may be treated by an iliac branch endoprosthesis (IBE) through brachial access for internal iliac artery (IIA) stenting. The aim of this study was to evaluate outcomes of the IBE using an "up-and-over" transfemoral technique in patients with prior aortic repair compared with the standard technique in patients with de novo iliac aneurysms.

Methods: We reviewed the clinical data of patients treated for aortoiliac aneurysms using Gore IBE (W.

Evolution from physician-modified to company-manufactured fenestrated-branched endografts to treat pararenal and thoracoabdominal aortic aneurysms.

Objective: The purpose of this study was to review treatment trends and outcomes of patients who underwent fenestrated-branched endovascular aneurysm repair (F-BEVAR) of pararenal aneurysms (PRAs) or thoracoabdominal aortic aneurysms (TAAAs) using physician-modified endografts (PMEGs) or company-manufactured devices (CMDs).

Methods: We reviewed the clinical data of 316 consecutive patients (242 male patients; mean age, 75 ± 8 years) who underwent F-BEVAR between 2007 and 2016. F-BEVAR was performed under two prospective investigational device exemption protocols since 2013.

Impact of onlay fusion and cone beam computed tomography on radiation exposure and technical assessment of fenestrated-branched endovascular aortic repair.

Objective: The objective of this study was to analyze the impact of advanced imaging applications and cone beam computed tomography (CBCT) on radiation exposure of the patient and operator and detection of technical problems during fenestrated-branched endovascular aortic repair (F-BEVAR) for treatment of pararenal aneurysms and thoracoabdominal aortic aneurysms (TAAAs).

Methods: We reviewed the clinical data of 386 consecutives patients (289 male; mean age, 75 ± 8 years) treated by F-BEVAR for 196 pararenal aneurysms and 190 TAAAs (mean, 3.4 ± 0.

Penetrating Aortic Ulcer and Intramural Hematoma.

Acute aortic syndromes include a variety of overlapping clinical and anatomic diseases. Penetrating aortic ulcer (PAU), intramural hematoma (IMH) and aortic dissection can occur as isolated processes or can be found in association. All these entities are potentially life threatening, so prompt diagnosis and treatment is of paramount importance.

Severe infolding of fenestrated-branched endovascular stent graft.

Infolding of a fenestrated-branched stent graft is an infrequent complication due to excessive oversizing. We report the case of an 89-year-old man who underwent a four-vessel fenestrated-branched endovascular aortic repair for a pararenal aortic aneurysm. Computed tomography angiography revealed severe infolding across the mesenteric-renal vessels.
