Transesophageal echocardiography (TEE) can be used to identify risk factors such as aortic atherosclerosis [2] before any sort of surgical manipulations involving aorta and its related structures. TEE has become an important noninvasive tool to diagnose acute thoracic aortic pathologies. TEE evaluation of endoleaks helps early detection and immediate corrective interventions. TEE is an invaluable imaging modality in the management of aortic pathology. TEE has to a large extent improved the patient outcomes.

PURPOSE: To evaluate risk factors for early (<30 days) type I endoleak following thoracic endovascular aortic repair (TEVAR). METHODS: A retrospective study was conducted of 439 consecutive patients (mean age 74.0±10.0 years; 333 men) who underwent TEVAR at a single center between June 2006 and June 2013. Pathologies included 237 aortic arch aneurysms and 202 descending thoracic aortic aneurysms (dTAA). Maximum TAA diameter was 63.6±13.7 mm. Among the distal aortic arch aneurysms, 124 required coverage of the left subclavian artery (LSA), while the remaining 113 arch aneurysms had debranching (n=40), the chimney technique (n=52), and a branched stent-graft (n=13)...

OBJECTIVE/BACKGROUND: Surveillance after endovascular aortic aneurysm repair (EVAR) is mandatory and computed tomography angiography (CTA) is considered the standard imaging modality, although patients are exposed to ionizing radiation and nephrotoxic contrast medium. The primary aim of this study was to determine the diagnostic efficacy of duplex ultrasound (DUS) and contrast enhanced ultrasound (CEUS) using CTA as the gold standard. The secondary aim was to determine the clinical consequences of endoleaks missed by DUS and CEUS, or CTA...

We herein report two cases of perigraft effusion mimicking graft infection after debranching thoracic endovascular repair for an anastomotic pseudoaneurysm of the distal ascending aorta. Both patients presented with a bulging tumor on the sternum. Enhanced computed tomography showed no endoleak, but extension of periprosthetic graft fluid to a subcutaneous sternal wound was present. We suspected a deep sternal wound infection; however, cultures of débrided tissues were negative. After drainage of the subcutaneous fluid or negative pressure wound therapy, both patients were doing well without recurrence of effusion...

OBJECTIVE: Gutters can be described as the loss of continuous apposition between the main body of the endograft, the chimney stent graft, and the aortic wall. Gutters have been associated with increased risk of type IA endoleaks and are considered to be the Achilles' heel of chimney endovascular aneurysm repair (ch-EVAR). However, there is no classification yet to classify and quantify gutter types after ch-EVAR. METHODS: Different gutter types can be distinguished by their morphologic appearance in two- and three-dimensional views and reconstructed slices perpendicular to the center lumen line...

In the modern endovascular era, abdominal aortic aneurysm repair is still not free of complications with re-interventions following endovascular aneurysm repair (EVAR) being more common than with open surgical repair. A variety of endovascular, open surgical and combined techniques were described according to the anatomical considerations and general health of the patient to achieve the best possible result after these complications. In cases of type Ib endoleak following aorto-uni-lateral EVAR for an abdominal aortic aneurysm, the use of the internal branched device (IBD) constitutes a safe and effective technique...

PURPOSE: To describe a sac embolization technique modification for type II endoleak prevention that makes a totally percutaneous approach feasible during endovascular aneurysm repair (EVAR) using the Excluder stent-graft. TECHNIQUE: Percutaneous access of the common femoral arteries is obtained and 2 suture-mediated closure systems are placed on each side. A 16-F or 18-F sheath is placed for delivery of the Excluder stent-graft main body and a 16-F sheath is used on the contralateral side...

OBJECTIVE: Endovascular aneurysm repair (EVAR) is widely used with excellent results, but its infectious complications can be devastating. In this paper, we report a multicenter experience with infected EVAR, symptoms, and options for explantation and their outcome. METHODS: We have reviewed all consecutive endograft explants for infection at 11 French university centers following EVAR, defined as index EVAR, from 1998 to 2015. Diagnosis of infected aortic endograft was made on the basis of clinical findings, cultures, imaging studies, and intraoperative findings...

OBJECTIVE: Intracranial blood blister-like aneurysm (BBA) is a rare type of aneurysm that lacks all layers of the arterial wall. These fragile aneurysms have the propensity to rupture with minimal manipulation, which makes them hazardous and difficult to treat. The present study evaluated the safety and feasibility of endovascular treatment of BBAs with the Willis covered stent. MATERIALS: Thirteen patients (7 men and 6 women, age range 28-68 years) who presented with ruptured BBAs and were treated with the Willis covered stent were retrospectively reviewed...

Thoracic endovascular aortic repair (TEVAR) is increasingly used in the treatment of acute type B aortic dissection. Type Ia endoleaks are a common complication of the procedure, but its clinical significance and the best treatment strategy remain poorly defined. We present a case of a type Ia endoleak following TEVAR in the treatment of acute type B aortic dissection. Chimney technique approach was used in an attempt to seal the endoleak. Although technical success was suboptimal, the patient remained clinically stable and event free...

A 75-year-old patient with severe comorbidities was treated with an Endurant(®) (Medtronic, USA) II endograft due to a ruptured abdominal aortic aneurysm (AAA). After four years of unremarkable follow-up, bilateral limb separation was detected. The patient underwent endovascular bridging without any complication. Although rarely detected in newer grafts, late bilateral type IIIa endoleaks can present and should be promptly repaired. Complex or ruptured AAAs treated with off-label use of endografts should be under closer surveillance using imaging tools for potential endoleaks or aneurysm sac growth...

Juxtarenal aortic aneurysms (JRAAs) are challenging to treat by endovascular aneurysm repair (EVAR) procedures. The chimney technique with EVAR (Ch-EVAR) is one of the feasible and less invasive treatments for JRAAs. However, the main concern of Ch-EVAR is the potential risk of "gutters," which can lead to type Ia endoleak (EL). Most type Ia ELs after Ch-EVAR procedures occurred intraoperatively, and these ELs could be treated using an endovascular technique. However, late-onset type Ia ELs could be extremely rare, which might have a fear of conservative treatment...

Endovascular aortic aneurysm repair (EVAR) is a predominant surgical procedure to reduce the risk of aneurysm rupture in abdominal aortic aneurysm (AAA) patients. Endoleak formation, which eventually requires additional surgical reoperation, is a major EVAR complication. Understanding the etiology and evolution of endoleak from the hemodynamic perspective is crucial to advancing the current posttreatments for AAA patients who underwent EVAR. Therefore, a comprehensive flow assessment was performed to investigate the relationship between endoleak and its surrounding pathological flow fields through computational fluid dynamics and image processing...
