To assess feasibility, efficacy and safety of carbon dioxide (CO2) digital subtraction angiography (DSA) to guide endovascular aneurysm repair (EVAR) in a cohort of patients with chronic kidney disease (CKD). After Ethical Committee approval, the records of 13 patients (all male, mean age 74.6 ± 8.0 years) with CKD, who underwent EVAR to exclude an abdominal aortic aneurysm (AAA) under CO2 angiography guidance, were reviewed. The AAA to be excluded had a mean diameter of 52.0 ± 8.0 mm. CO2 angiography was performed by automatic (n = 7) or hand (n = 6) injection...

BACKGROUND: We report a preliminary experience about endovascular aortic repair (EVAR) of infrarenal abdominal aneurysm (iAAA) with severe proximal aortic neck angulation using the Aorfix(TM) stent graft. METHODS: Data of consecutive patients with iAAA with severe proximal neck angulation submitted to endovascular repair between September 2012 and December 2014 in two Italian centres of Vascular and Endovascular Surgery were retrospectively reviewed and outcomes analyzed using the software JMP 5...

BACKGROUND: The chimney technique has been developed for the treatment of complex aortic aneurysms. We analyzed the midterm to long-term outcomes of this approach from a single- centre experience. METHODS: From October 2008 to July 2016, 58 patients underwent endovascular aortic aneurysm repair using the chimney technique. Indications for treatment were thoracic aortic aneurysm (TAA) (n = 11), thoracoabdominal aortic aneurysm (TAAA) (n = 2), pararenal aortic aneurysm (PAAA) (n= 15), aortoiliac/isolated hypogastric artery aneurysm (n = 25), type I endoleak after previous TEVAR/EVAR (n=4), proximal pseudoaneurysm after AAA open repair (n = 1)...

BACKGROUND: An abdominal aortic aneurysm (AAA) (pathological enlargement of the aorta) is a condition that can occur as a person ages. It is most commonly seen in men older than 65 years of age. Progressive aneurysm enlargement can lead to rupture and massive internal bleeding, which is fatal unless timely repair can be achieved. Despite improvements in perioperative care, mortality remains high (approximately 50%) after conventional open surgical repair. Endovascular aneurysm repair (EVAR), a minimally invasive technique, has been shown to reduce early morbidity and mortality as compared to conventional open surgery for planned AAA repair...

OBJECTIVE: A retrograde technique through the gap between the distal stent landing zone and the iliac artery wall has been applied to treat type II endoleak after endovascular aortic aneurysm repair (EVAR). In this study, we tried to investigate its efficacy in the management of type III endoleak and intraoperative accidental events. METHODS: We reported 2 complications of EVAR that were difficult to treat with conventional methods. One patient had a sustained type III endoleak after EVAR, and the right renal artery was accidentally sealed by a graft stent in the other patient during the operation...

PURPOSE: Postcoarctation thoracic aortic aneurysm formation is one of the most serious complications for coarctation of aorta. Open surgery to repair these aneurysms is associated with high morbidity and mortality. Endovascular therapy is an attractive alternative to open surgery. We have studied the efficacy and safety of endovascular therapy for postcoarctation thoracic aortic aneurysms, and will share our findings and experience through this document. METHODS: The data was retrospectively collected on consecutive patients who were presented with postcoarctation thoracic aortic aneurysms at our medical center...

INTRODUCTION: Prophylactic open surgery is the standard practice in patients with connective tissue and thoraco-abdominal (TAAA) and aortic arch disease. Branched and fenestrated devices offer a less invasive alternative but there are concerns regarding the durability of the repair and the effect of the stent graft on the fragile aortic wall. The aim of this study was to evaluate mid-term outcomes of fenestrated and/or branched endografting in patients with connective tissue disease. METHODS: All patients with connective tissue disease that underwent TAAA or arch aneurysm repair using a fenestrated and/or branched endograft in a single high volume centre between 2004 and 2015 were included...

OBJECTIVES: The purpose of the present study was to compare the long-term survival in matched cohorts of patients with infrarenal abdominal aortic aneurysm (AAA) undergoing an elective open repair (OR) or an endovascular aneurysm repair (EVAR). MATERIALS AND METHODS: Patients with a primary elective repair of an infrarenal aortic aneurysm between 1998 and 2006 were identified in a retrospective review of our single centre database. EVAR and OR patients were matched with respect to age, gender, renal disease, tobacco use, hypertension, chronic obstructive pulmonary disease and coronary artery disease...

Graft infection following aortic aneurysms repair is an uncommon but devastating complication; its incidence ranges from <1% to 6% (mean 4%), with an associated perioperative and overall mortality of 12% and 17.5-20%, respectively. The most common causative organisms are Staphylococcus aureus and Escherichia coli; causative bacteria typically arise from the skin or gastrointestinal tract. The pathogenetic mechanisms of aortic graft infections are mainly breaks in sterile technique during its implantation, superinfection during bacteremia from a variety of sources, severe intraperitoneal or retroperitoneal inflammation, inoculation of bacteria during postoperative percutaneous interventions to manage various types of endoleaks, and external injury of the vascular graft...

Endovascular aortic aneurysm repairs rely heavily on radiologic imaging modalities for preoperative surveillance, intraoperative management, and postoperative follow-up. Ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI) and angiography all have utility at different stages of management. Often one imaging modality compliments another by providing supplementary information. Data from the imaging exams must be synthesized into one coherent plan for managing patients with aortic aneurysms...

PURPOSE: To determine the midterm outcomes of internal iliac artery (IIA) coverage by a stent-graft in endovascular aortic aneurysm repair (EVAR) under specific anatomic and technical circumstances. MATERIAL AND METHODS: From January 2003 until January 2014, 57 patients with aortoiliac aneurysms, including 20 with 24 IIA aneurysms (IIAAs), underwent EVAR with IIA coverage. IIAA diameter change or IIA thrombosis, buttock claudication, type II endoleak, and secondary interventions related to the IIA were studied...

The majority of the ruptured abdominal aortic aneurysms today is treated endovascularly. In cases with short aneurysm neck, chimney technique can be used to extend landing zone in emergency setting. Additionally, the repositioning ability of C3 delivery system (Gore & Associates) allows better positioning in cases with challenging anatomy. In our experience, proximal reposition of partially deployed device can be problematic in some patients. We present a case of endovascular repair of ruptured abdominal aortic aneurysm using chimney technique where proximal reposition was achieved by snaring the aortic device via axillary access...

OBJECTIVES: Endovascular aneurysm repair (EVAR) is considered the treatment of choice for abdominal aortic aneurysms with suitable anatomy. In order to improve radiation safety, European Directive (2013/59) requires member states to implement diagnostic reference levels (DRLs) in radio-diagnostic and interventional procedures. This study aimed to determine local DRLs for EVAR across five European centres and identify an interim European DRL, which currently remains unestablished. METHODS: Retrospective data was collected for 180 standard EVARs performed between January 2014 and July 2015 from five specialist centres in Ireland (n=2) and Italy (n=3)...

Aortic graft infection is a potentially lethal complication of open and endovascular repair of aortic aneurysms. Graphene is the only existing two-dimensional material, and its unique structure gives graphene and its derivatives a plethora of original characteristics. Among other characteristics, graphene demonstrates bacteriostatic and bactericidal effects that could potentially resolve the problem of graft infection in the future. Data already exist in literature supporting this antibacterial effect of graphene oxide and reduced graphene oxide...
