PURPOSE: Fusion of preoperative data with intraoperative X-ray images has proven the potential to reduce radiation exposure and contrast agent, especially for complex endovascular aortic repair (EVAR). Due to patient movement and introduced devices that deform the vasculature, the fusion can become inaccurate. This is usually detected by comparing the preoperative information with the contrasted vessel. To avoid repeated use of iodine, comparison with an implanted stent can be used to adjust the fusion...

TEVAR is a well-stablished treatment of descending thoracic aneurysms and increasingly complex endovascular procedures are being performed including aortic arch and ascending aorta. However, follow-up complications may be expected, which will enhance the need of alternative approaches such as transapical, in case of complex anatomies and reinterventions. We report the case of a man with prior history of ischemic cardiopathy and multiple endovascular aortic interventions with proximal landing in zone 1 and distal landing proximal to celiac trunk...

INTRODUCTION: Only 3 cases of aorto-cisterna chyli fistula have been described in the literature but none with a resulting pseudoaneurysm (PSA). CASE REPORT: A 68-year-old man presented following a motor vehicle collision. Imaging revealed a retroperitoneal hematoma with enhancement of the cisterna chyli, representing aortic to cisterna chyli fistula. Three days later CTA showed resolution of the fistula, but revealed a PSA. The patient underwent arteriography that confirmed the PSA, and then a CT-guided thrombin injection was performed...

Aortoiliac occlusive disease (AOID) results in varying degrees of pelvic and lower extremity arterial insufficiency. Treatment approach has evolved and endovascular therapies are being successfully reported for high-grade lesion. However, Trans Atlantic Inter-Society Consensus (TASC) D often necessitates open revascularization. Disease limited to the infrarenal segment does not typically affect intestinal perfusion in the absence of visceral aortic or mesenteric vessel involvement. Chronic mesenteric ischemia most commonly occurs due to atherosclerotic disease of two or three of the mesenteric vessels...

BACKGROUND:  Post-coarctation of the aorta (CoA) pseudoaneurysms is a complication of open repair. Thoracic endovascular repair (TEVAR) is feasible but complicated by proximity to the supra-aortic trunks and severe arch angulation. METHODS:  We describe three cases of post-CoA pseudoaneurysms treated with custom-made Relay stent grafts (Vascutek, Scotland). RESULTS:  Technical and clinical success was achieved in all three cases with no mortality, morbidity, endoleaks, or complications...

Preservation of the residual hypogastric artery (HGA) in patients with previous endovascular aortic aneurysm repair (EVAR) may require complex operative strategies. We report an alternative technique to preserve the residual HGA with the Gore Excluder Iliac Branch endoprosthesis (IBE) in urgent situations. MethodsWe report the case of two high-risk patients (unfit for open surgery), with previous EVAR and exclusion of one HGA, treated in emergency setting. Both patients met the anatomical requirements for Gore IBE use...

BACKGROUND: Although iodinated contrast (IC) agents are commonly used in endovascular aneurysm repair (EVAR), perioperative use in patients with renal dysfunction or IC allergies is avoided. Carbon dioxide (CO2 )-guided angiography is a promising alternative. We aimed to evaluate short-term and mid-term outcomes of EVAR using CO2 -guided angiography. METHODS: Three hundred and eighty-one patients who underwent EVAR from January 2012 to September 2016 were retrospectively reviewed and divided into an IC-EVAR group (n=351) and CO2 -EVAR group (n=30)...

Penetrating aortic ulcer (PAU) is an acute aortic syndrome that can proceed to life-threatening aortic dissection or even aortic rupture. Isolated iliac aneurysms are relatively rare and often asymptomatic due to their deep pelvic location but are frequently associated with high mortality with rupture. We report a case of a 68-year-old man with a symptomatic penetrating ulcer in the descending aorta and an asymptomatic right iliac aneurysm involving the common and internal iliac arteries. The patient was successfully treated by endovascular repair in a single-stage manner using stent grafts in the descending aorta and right common iliac artery after coil embolization of the right internal iliac artery...

We describe the successful surgical treatment of a 71-year-old man affected by right buttock claudication after a right internal iliac artery (IIA) coil embolization as an adjunct to endovascular iliac artery aneurysm repair. Computed tomography angiography revealed extensive aortoiliac calcifications and thrombus in the vessel walls. Despite patency of the contralateral IIA and preservation of right distal collateral flow through ipsilateral hypogastric branches, the symptom was persistent and disabling. The high-risk patient underwent an "open" repair of the infrarenal abdominal aneurysm with removal of the entire stent-graft and concomitant revascularization of the right IIA...

An 87-year-old woman presented to the emergency department with a 2-week history of progressively worsening shortness of breath, fever and generalised myalgia. She underwent a transcatheter Portico aortic valve implantation for severe symptomatic aortic stenosis 3 months prior to this presentation. Examination revealed a temperature of 40°C and a systolic murmur in the aortic area. Inflammatory markers were elevated, and blood cultures were positive for methicillin-sensitive Staphylococcus aureus A possible diagnosis of infective endocarditis was made as one major and one minor criterion in the modified Duke criteria were fulfilled...

OBJECTIVES: Aortic neck diameter is an independent anatomical feature that is poorly understood, yet potentially linked to proximal seal failure and adverse outcome following standard EVAR. The aim of this study was to assess whether large proximal aortic neck (LAN) diameter is associated with adverse outcome using prospectively collected individual patient data from The Global Registry for Endovascular Aortic Treatment (GREAT). METHODS: A total of 3166 consecutive patients, from 78 global centres, receiving Gore Excluder stent grafts for infrarenal abdominal aortic aneurysm repair between 2011 and 2017 were included...

OBJECTIVES: This study aims to report mid-term follow-up outcomes of a series of TAAD patients treated with TEVAR in China. BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has been used to treat type A aortic dissection (TAAD) for years. However, by comparing public reports, their outcomes which were based on different sample sizes show inconsistency. METHODS: Between January 2001 and December 2015, there were 56 patients with TAAD received TEVAR identified in 5 medical centers...

Objectives: Stent implantation for the treatment of aortic coarctation has become a standard approach for the management of older children and adults. Criteria for optimal stent design and construction remain undefined. This study used computational modelling to compare the performance of two generations of the Cheatham-Platinum stent (NuMED, Hopkinton, NY, USA) deployed in aortic coarctation using finite element analysis. Design: Three-dimensional models of both stents, reverse engineered from microCT scans, were implanted in the aortic model of one representative patient...

Mitroflow aortic prosthesis dysfunction in case of complex vascular disease is considered a challenging scenario. Because of the high risk for surgical reoperation and the presence of chronic aortic dissection originated from a calcified Kommerel diverticulum, we considered to perform a transapical valve-in-valve transcatheter aortic valve implantation (TAVI) procedure. Myocardial ischemia is a dreadful complication reported in valve-in-valve TAVI procedures, mainly in patients with degenerated Mitroflow aortic bioprostheses...
