Purpose: To analyze our experience with endovascular stent-grafting of descending aortic aneurysms in high-risk patients.
Methods: Nineteen patients underwent endovascular stent-graft repair of descending aortic aneurysms using the Talent Stent Graft System (Medtronic). All patients were considered high-risk for open surgical repair due to their age, requirement for emergency surgery, and comorbidities. Computed tomography and/or MR tomography were performed at 3, 6 and 12 months postoperatively and thereafter every 12 months.
Results: Secondary technical success was 100%. Thirty-day mortality was 5%. Incidence of postoperative stroke and paraplegia were 5% each. One patient required a second stent-graft due to a type I endoleak during the same hospital stay (primary technical success 95%). All patients have been followed for a median of 20 months. No migration, wire fractures or endoleak appeared during follow-up.
Conclusion: Endovascular stent-grafting had a low 30-day mortality and morbidity in high-risk patients. One patient developed an aortoesophageal fistula 40 days after stent implantation. Stent-graft repair is a valuable supplement to surgical therapy in high-risk patients.

Purpose: To report a case series on using a novel semi-branch feature in custom-made stent-grafts in the endovascular treatment of complex aortic aneurysms and summarize the contemporary usage of this technology.
Case Series: Four patients underwent endovascular aortic aneurysm repair (EVAR) with a custom-made semi-branch stent-graft (Semi-Branch Endovascular Aortic Aneurysm Repair [SBEVAR]). Two male patients, 75- and 76-year-old, were treated due to failed EVAR with late-type Ia endoleak, and the other two, 80- and 55-year-old male patients, due to a juxta-renal aortic abdominal aneurysm (JRAAA).

Multiple Aneurysmal Arterial Disease (MAD) is an extremely rare arterial vascular condition and is produced by an abnormal alteration of smooth muscle cells and neutrophils, producing a multiple-aneurysmal degeneration. We present the case of a 36-year-old patient with a MAD in the cerebral territory and extremities with no surgical indication; however, with an aneurysm of the right inferior renal segmental artery, inferior mesenteric artery, left common iliac artery, and right internal iliac artery with surgical indication. An open approach with single-stage surgical repair, including graft interposition, bypass, exclusion, and vascular reimplantation, was performed.

Objective: As aneurysmal disease is progressive, proximal disease progression and para-anastomotic aneurysms are complications experienced after open infrarenal abdominal aortic aneurysm repair (AAA). As such, fenestrated or branched endovascular repair (F/BEVAR) may be indicated in these patients. Data describing fenestrated endovascular aneurysm repair after prior open repair are limited to institutional databases.

Objective: The aim of this single-center case series is to demonstrate that an ultra-low dose (ULD) can be routinely achieved in the hybrid operating room in standard endovascular aortic repair (EVAR) for infrarenal abdominal aortic aneurysm by adjusting the manufacturer's predefined imaging parameters, hardware configurations and user protocols (including benchmarking).
Methods: The hybrid operating room manufacturer predefined EVAR software setup of the dose exposure control software (OPTIQ, Siemens Healthineers, Forchheim, Germany) at our university medical center was screened for possible improvements regarding radiation dose application. Tests on a water-equivalent as well as polymethyl methacrylate phantom model to assess the impact of technical settings were performed, including comparison of settings for exposure control software, different magnification, collimation configurations and detector distance.
