Postoperative thoracic aortic false aneurysm is a challenging complication of aortic surgery. We describe our surgicalapproach for an 8-cm thoracic aorta false aneurysm in a 59-year-old woman who had previously undergone aortic surgery. Surgery must be planned carefully because massive hemorrhage during resternotomy is a dreadful complication of postoperative false aneurysm surgery. We decided to start cardiopulmonary bypass before resternotomy and use a ventricular vent from the apex, an endo-vent from the pulmonary artery, and an endo-balloon with antegrade blood cardioplegia.

Background: The aim of this study was to compare intravascular ultrasound (IVUS) assistance for endovascular aortic aneurysm repair (EVAR) to standard assistance by angiography. Methods: From June 2015 to June 2017, 173 consecutive patients underwent EVAR. In this group, 69 procedures were IVUS-assisted with X-ray exposure limited to completion angiography for safety purposes because an IVUS probe does not yet incorporate a duplex probe (group A), and 104 were angiography-assisted procedures (group B).

Background: Penetrating aortic ulcer (PAU) is an atherosclerotic lesion penetrating the elastic lamina and extending into the media of the aorta. It may evolve into intramural hematoma, focal dissection, pseudoaneurysm, and eventually rupture. The purpose of this study was to evaluate the effectiveness of a totally intravascular ultrasound (IVUS)-assisted endovascular exclusion of PAU. Methods: Thirteen consecutive patients (median age 66 years) underwent IVUS-assisted endovascular exclusion of PAU.

A 77-year-old male patient presented with a symptomatic, 66-mm pararenal aortic aneurysm. The patient was classified as unsuitable for open surgery due to significant comorbidities. Fenestrated or branched endografts were contraindicated due to the poor iliac access (6 mm diameter). A double Nellix with chimney endovascular aneurysm sealing (ChEVAS) technique was selected to exclude the pararenal aortic aneurysm and to preserve renal arteries and the superior mesenteric artery.

Following the definition given by the recent ESVS guidelines, juxtarenal abdominal aortic aneurysm (JAAA) is defined as an aneurysm extending
up to but not involving the renal arteries, necessitating suprarenal aortic clamping for open surgery, i.e. a short neck (<10 mm). JAAA repair
always represents a challenge intervention, either by open or endovascular means, mostly related to the renal arteries involvement. Concerning
endovascular repair, different options can be considered. Among them, fenestrated endografts (FEVAR) should be considered as a first option1,

We report a case of Yersinia enterocolitica septicemia in a 63-year-old patient admitted to the Vascular Surgery Department of Umberto I Hospital (Rome, Italy) for an abdominal aortic aneurysm. The microorganism, recovered from both peripheral blood cultures and aneurysmatic aortic wall specimens, was identified as Y. enterocolitica using matrix-assisted laser desorption ionization-time of flight analysis (MALDI-TOF MS) and 16S rDNA gene sequencing. The isolate responsible for septicemia belonged to the O:9 serotype (biogroup 2).
