We present a case of isolated rectal ischaemia, a rare complication after emergency surgery for a ruptured abdominal aneurysm. We discuss the possible aetiology of this condition and how this rare condition may be missed unless care is taken at the time of reoperation.

Abdominal aortic aneurysms are relatively common and often life-threatening, with especially high mortality after aneurysm rupture. The introduction of endovascular aneurysm repair, a minimally invasive alternative to traditional open repair, led to decreased mortality and morbidity in randomized controlled trials, but these trials were conducted in highly selected patients and providers and were underpowered to detect differences in rare adverse events throughout follow-up. With observational studies of Medicare beneficiaries, we demonstrate that the randomized trial results are generalizable to the majority of patients undergoing abdominal aortic aneurysm repair in the United States...

OBJECTIVE: Preloaded endovascular delivery systems expand the anatomic eligibility for complex aortic repair by requiring only one iliac access vessel and providing a stable platform for guiding sheaths into challenging target vessels. This article reports the lessons learned and early clinical outcomes using a modified preloaded delivery system for fenestrated endovascular aneurysm repair (FEVAR) in three aortic centers in Europe. METHODS: From October 2015 to March 2016, consecutive patients presenting with extensive aortic aneurysm treated with a modified preloaded FEVAR were prospectively enrolled from three high volume European aortic centers...

OBJECTIVE: Reported are initial 12-month outcomes of patients with chronic symptomatic aortic dissection managed by the Streamliner Multilayer Flow Modulator (SMFM; Cardiatis, Isnes, Belgium). Primary end points were freedom from rupture- and aortic-related death, and reduction in false lumen index. Secondary end points were patency of great vessels and visceral branches, and freedom of stroke, paraplegia, and renal failure. METHODS: Out of 876 SMFM implanted globally, we have knowledge of 542...

OBJECTIVE: Finite element analysis (FEA) has been suggested to be superior to maximal diameter measurements in predicting rupture of abdominal aortic aneurysms (AAAs). Our objective was to investigate to what extent previously described rupture risk factors were associated with FEA-estimated rupture risk. METHODS: One hundred forty-six patients with an asymptomatic AAA of a 40- to 60-mm diameter were retrospectively identified and consecutively included. The patients' computed tomography angiograms were analyzed by FEA without (neutral) and with (specific) input of patient-specific mean arterial pressure (MAP), gender, family history, and age...

BACKGROUND: Severe aortic tortuosity of the access route often prevents successful complete exclusion of an aneurysm in thoracic endovascular aortic repair (TEVAR). CASE PRESENTATION: We performed antegrade TEVAR on a 79-year-old man with right hemiparesis. We deployed the stent graft from the ascending aorta with a tube graft conduit to treat a descending thoracic aortic aneurysm associated with rickets and multiple comorbidities. Although the application of a ministernotomy diminished the potential advantages of endovascular treatment in view of less invasive surgery, antegrade TEVAR using an ascending aortofemoral through-and-through wire technique was a good option in this patient because a conventional retrograde approach was not feasible due to his severely tortuous aorta...

OBJECTIVES: To analyse the results and review the literature about thoracic aortic endovascular repair (TEVAR) for type B acute aortic dissection (TBAAD) complicated by descending thoracic aortic aneurysm (DTA) in the hyperacute or acute phases. METHODS: This was a multicentre, observational descriptive study. Inclusion criteria were TBAAD with a DTA of ≥50 mm, TBAAD on an already known aneurysmal descending thoracic aorta, and TBAAD presenting with an enlarged aorta with a total diameter <50 mm, but with >50% diameter increase compared with a previous computed tomography angiography (CTA) showing a non-dissected aorta with normal sizing...

INTRODUCTION: and Objectives: Implications of aortic neck dilatation following EVAR are unclear. Previous studies are limited to comparisons of individual, early-generation devices. We compared aortic neck dilatation among contemporary stent-grafts. METHODS: We reviewed pre- and post-op CTA for EVARs performed from 2008-2014. Images were analyzed using 3-D centerline reconstructions. Aortic neck diameter was measured in orthogonal planes at and 10 mm below the lowest renal artery...

BACKGROUND: Ascending and thoracic aortic dissections progress into thoracoabdominal aneurysms 20-40% of the time, due to the initial aortic injury with associated weakness of the aortic wall. The increased firmness of the intimal flap usually results in a collapsed true lumen that does not spontaneously re-expand even with progressive dilatation of the aorta. In an effort to identify a safe and effective treatment path for this complex disease process, we present 4 cases illustrating successful sequential thoracic endovascular aortic repair (TEVAR) and fenestrated endovascular aortic repair (FEVAR)...

PURPOSE: Abdominal aortic aneurysm (AAA) can present with symptoms because of aneurysmal compression of adjacent organ systems. This condition has always been treated by open surgical repair. Here, we report a case of an AAA complicated by inferior vena cava (IVC) thrombosis and deep venous thrombosis (DVT) due to IVC compression by aneurysm successfully treated by endovascular aneurysm repair (EVAR). CASE REPORT: A 50-year-old man presented with three-day right lower extremity edema...

We performed an exome-wide association study (EWAS) to identify genetic variants - in particular, low‑frequency or rare variants with a moderate to large effect size - that confer susceptibility to aortic aneurysm with 8,782 Japanese subjects (456 patients with aortic aneurysm, 8,326 control individuals) and with the use of Illumina HumanExome-12 DNA Analysis BeadChip or Infinium Exome-24 BeadChip arrays. The correlation of allele frequencies for 41,432 single nucleotide polymorphisms (SNPs) that passed quality control to aortic aneurysm was examined with Fisher's exact test...

OBJECTIVE Obstructive sleep apnea (OSA) is associated with the progression of abdominal and thoracic aortic aneurysms. However, the role of OSA in the overall outcome of intracranial aneurysms (IAs) has not yet been established. Authors of this report investigated the role of OSA in the overall outcome of IAs. METHODS Radiological and clinical data on patients (from 2010 through 2015) with confirmed IA were retrospectively reviewed. Significant differences between the OSA and non-OSA groups were determined using a chi-square test...

PURPOSE: To report a heretofore undescribed complication seen on imaging after endovascular aortic sealing (EVAS). CASE REPORT: A 77-year-old woman was treated with the Nellix EVAS device for an infrarenal aortic aneurysm. After a normal computed tomography (CT) scan at 15 days, the 6-month CT showed the onset of perianeurysmal inflammatory tissue. The patient was asymptomatic, and blood tests were normal. Imaging suggested a nonaggressive inflammatory process, so a conservative approach was adopted with close follow-up...
