The incidence of aneurysm after open surgical repair of coarctation is 11% to 24%. If the condition is left untreated, fatal rupture may occur. Thoracic endovascular aortic repair (TEVAR) has been reported as a feasible and safe alternative to open surgical repeated procedures in this context. However, TEVAR might be challenging because of the proximity of the pathologic condition to the supraaortic vessels and the ongoing presence of the coarctation. We report a unique case of a 48-year old man undergoing TEVAR because of aortic aneurysm after previous surgical coarctation treatment and successful closure of the coarctation with a vascular plug device...

We describe a very rare case of a 67-year-old man with multiple saccular aortic aneurysms throughout the entire aorta due to antineutrophil cytoplasmic antibody-associated vasculitis (AAV). The patient underwent staged aortic surgical procedures, including stent-graft insertion for a left iliac artery aneurysm, thoracic endovascular aortic repair for a descending aortic aneurysm, and total replacement of the ascending aorta and aortic arch with the use of high-dose steroids to control inflammation. The histologic findings demonstrated that the damage to the vasa vasorum of the adventitia resulting from AAV caused ischemia of the media, resulting in the formation of saccular aneurysmal changes...

Methylmethacrylate is a prosthetic material commonly used for the reconstruction of large chest wall defects. We present the first reported case of delayed methylmethacrylate plate migration, which resulted in an aortic pseudoaneurysm with aortopulmonary fistula. Treatment management, including staged repair combining endovascular and open approaches, is also discussed.

Endovascular repair of abdominal aortic aneurysms has widely replaced the open surgical repair due to its minimal invasive nature and the accompanying lower perioperative mortality and morbidity. During the past two decades, certain improvements and developments have provided a wide variety of endograft structural designs and geometric patterns, enabling the physician to approach a more patient-specific treatment of AAA. This review presents the currently available aortic endografts and describes the clinical, technical and mechanical characteristics of them...

OBJECTIVES: This study aims to determine whether warfarin therapy influences the occurrence of endoleaks or aneurysm sac enlargement after endovascular aortic repair (EVAR). METHODS: A total of 367 patients who underwent EVAR for abdominal aortic aneurysm between 2007 and 2013 were recruited for this study. Satisfactory follow-up data including completed computed tomography scan follow-up for more than 2 years were available for 209 patients, and the mean follow-up time was 37 ± 12 months...

Occlusion of an internal iliac artery or its branches is sometimes required prior to abdominal endovascular aneurysm repair. The Amplatzer vascular plug (AVP) is a useful device for this purpose, but it requires a large lumen catheter or guiding sheath to place it in the intended artery. We propose an anchor balloon technique for advancing this guiding sheath/catheter through a tortuous or angulated iliac artery for AVP placement.

PURPOSE: To evaluate the feasibility, safety, and outcome of transcatheter embolization using ethylene vinyl alcohol copolymer (EVOH) of type I endoleaks associated with endovascular abdominal aortic aneurysm repair. PATIENT POPULATION AND METHODS: Retrospective chart review was performed to identify 8 consecutive patients who had undergone EVOH embolization for type I endoleaks between 2012 and 2015. The primary approach used to access the endoleak was the perigraft technique, where the endoleak itself is catheterized at the anastomotic site...

Inadvertent coverage of origin of internal iliac artery (IIA) during endovascular aneurysm repair may lead to type II endoleak. Except for open surgery, the endovascular solution is limited. We report a case with such complication that was successfully treated with coil embolization using retrograde extrastent approach. This is a new technique that has not been reported before, and as such, had been useful in the treatment of type II endoleak from IIA as an alternative to open ligation of IIA origin.

: Laparoscopic surgery (LS) is the minimally invasive alternative to open surgery and endovascular approach for treating major aortic diseases. Only few reports in the literature describe the long-term outcomes of the laparoscopic approach for major vascular diseases. Furthermore, the widespread use of endovascular techniques has limited the use of LS to wellselected patients. This review evaluated the results of LS for aortic disease and compared the clinical outcomes of laparoscopic technique with those of open and endovascular surgery...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) requires large-bore vascular access due to the considerable diameters of the endoprosthesis and delivery device. The preclose technique preceding endograft delivery has opened the door for an evolved access strategy. In addition, treatment under local anesthesia offers the advantage of optimal neuromonitoring. The goal of this study was to analyze the efficacy and safety of percutaneous TEVAR under local anesthesia. METHODS: All patients undergoing TEVAR in an elective setting at the Antwerp University Hospital between June 2012 and June 2015 were prospectively entered into an endovascular database...

OBJECTIVES: To determine whether follow-up survival is better after elective endovascular aneurysm repair (EVAR) than open surgical repair (OSR) for intact abdominal aortic aneurysm (AAA), we combined 5-year survival curves themselves of EVAR and OSR in randomized controlled trials (RCTs) and propensity-score matched (PSM) studies. METHODS: Eligible studies were RCTs or PSM studies of elective EVAR versus OSR enrolling patients with intact AAA and reporting 5-year (at least) survival curves...

BACKGROUND: Follow-up computed tomography angiography (CTA) scans add considerable postimplantation costs to endovascular aneurysm repairs (EVARs) of abdominal aortic aneurysms (AAAs). By building a risk model, we hope to identify patients at low risk for aneurysm sac enlargement to minimize unnecessary CTAs. METHODS: 895 consecutive patients who underwent EVAR for AAA were reviewed, of which 556 met inclusion criteria. A Probit model was created for aneurysm sac enlargement, with preoperative aneurysm morphology, patient demographics, and operative details as variables...

BACKGROUND: Hospital readmission rates after surgery may represent an overall hospital effect or a combination of specialty and patient effects. We hypothesized that hospital readmission rates for procedures within specialties were more strongly correlated than rates across specialties within the same hospital. STUDY DESIGN: For general, orthopedic, and vascular specialties at Veterans Affairs hospitals during 2008-2014, 30-day risk-adjusted readmission rates were estimated for six high-volume procedures and each specialty...

PURPOSE: To compare the efficacy of an embolization agent with sclerosing properties (made of chitosan and sodium tetradecyl sulfate, CH-STS) with a similar embolization agent but without sclerosing properties (made of chitosan, CH) in treating endoleaks in a canine endovascular aneurysm repair model. METHODS: Two chitosan-based radiopaque hydrogels were prepared, one with STS and one without STS. Their rheological, injectability, and embolizing properties were assessed in vitro; afterwards, their efficacy in occluding endoleaks was compared in a canine bilateral aneurysm model reproducing type I endoleaks (n = 9 each)...
