OBJECTIVE: Data in literature suggest iliac artery dilatation and endograft retraction as complications after endovascular aneurysm repair. However, mainly older generation endografts were included. Therefore, we sought to evaluate the distal sealing zone chronological changes after endovascular aneurysm repair with newer generation stent-grafts. METHODS: Clinical and radiological data of patients with abdominal aortic aneurysms treated with endovascular aneurysm repair between January 2010 and December 2013 were reviewed...

BACKGROUND: Patent foramen ovale (PFO) closure after a cryptogenic cerebral ischemic event is a routinely procedure. The most used device is Amplatzer™ PFO Occluder 25mm, but PFOs with complex anatomy require larger device for closure. We compared Amplatzer™ Septal Occluder (ASO) device versus Amplatzer™ PFO Occluder 30 or 35mm (A-PFO 30/35) about the safety of procedure and the presence of residual shunt during the follow-up. METHODS: From June 2002 to July 2016, 355 patients (pts) with PFO undergone closure at our institution...

Perigraft seroma (PGS) is a relatively rare complication of aortoiliac reconstructive surgery. We herein describe a case of a large PGS that was managed by utilizing a hybrid technique of relining the original graft with simultaneous open drainage. An 86-year-old man with a 17.3-cm diameter PGS after prosthetic bifurcated graft replacement for abdominal aortic aneurysm was admitted to our hospital. He presented with abdominal distension and discomfort, and had difficulty in taking food. The entire relining of the original covered stent graft with GORE® EXCLUDER® using aortic extension cuff and iliac extenders and simultaneous open evacuation of PGS were successfully performed...

A patent foramen ovale (PFO) is implicated in several pathologic processes, including that of cryptogenic stroke (cCVA). Recent trials identify "high-risk" PFOs in patients with cCVA as likely to benefit from percutaneous closure. The younger the patient (<60 years old) the more likely a PFO may be attributable to the cCVA. The RoPE Score index helps determine the likelihood that an existing PFO is related to a cCVA. This may help guide the clinician and patient when contemplating percutaneous PFO closure...

Currently, there is a wide range of commercially available endografts for infrarenal abdominal aortic aneurysm (AAA) repair. Results of long-term follow up after endovascular aneurysm repair (EVAR) are limited. Thereby, the durability of these endografts and the difference between manufacturers is not fully clear. In this review, studies with mid- and long-term results, with a minimum median follow up of 36 months per endograft, were included describing results with Cook Zenith? Flex? endograft (Cook Medical Inc...

OBJECTIVE: To compare two endograft types, the original GORE EXCLUDER AAA endoprosthesis (W. L. Gore & Associates, Flagstaff, Ariz) with the repositionable GORE EXCLUDER featuring the C3 delivery system, which allows repositioning of the proximal part of the graft to achieve accurate placement in relation to the renal arteries, in unselected patients with aortoiliac aneurysms. In a second nested, substudy we investigated the relative effect of the standard Gore and Gore Dryseal introducer sheaths on intraoperative transfusion needs...

In selected cases of endovascular aortic repair (EVAR) of an abdominal aortic aneurysm, such as patients with tortuous proximal aortic neck, achieving a successful cannulation can sometimes be difficult. Herein, we described a novel cross-wire technique to help overcome such anatomical variations. During the EVAR procedure among our 5 cases, the main body of the Gore Excluder Stent Graft was deployed through an ipsilateral guidewire. Because of a large angle between the contralateral guidewire and the contralateral short limb of the main body, a successful traditional cannulation was unfeasible...

Marfan syndrome is a heritable connective tissue disorder affecting skeletal, ocular and cardiovascular systems. Cardiovascular manifestations comprise aneurysmal dilatation of aortic root, aortic dissection and rupture; peripheral arterial aneurysms have been reported in femoral, iliac and subclavian arteries with surgical reconstruction as the first-line therapeutic option. We report a Marfan patient with a symptomatic aneurysm of left subclavian artery in the intrathoracic retro-clavicular space; instead of open surgical resection, an endovascular solution was successfully applied by use of a flexible self-expanding stent-graft (W...

Most studies of immunosuppressive therapy (IST) in myelodysplastic syndromes (MDS) are limited by small numbers and their single-center nature, and report conflicting data regarding predictors for response to IST. We examined outcomes associated with IST and predictors of benefit in a large international cohort of patients with MDS. Data were collected from 15 centers in the United States and Europe. Responses, including red blood cell (RBC) transfusion independence (TI), were assessed based on the 2006 MDS International Working Group criteria, and overall survival (OS) was estimated by Kaplan-Meier methods...

INTRODUCTION: Although endovascular therapy is becoming an alternative to open surgical repair of splenic artery aneurysms (SAAs), reports on the use of stent grafts for SAA repair are limited. We present our experience of endovascular therapy using a stent graft for the treatment of an SAA that had ruptured into the gastric lumen. We also reviewed 18 cases of stent graft repair for SAAs, including the present case. CASE REPORT: A 43-year-old man was admitted due to hematemesis...

BACKGROUND: Failure of endovascular aneurysm repairs (EVARs) requiring open conversion remains a major challenge. We analyzed indications for repair, operative strategies, and outcomes with a focus on iliac artery degeneration after endograft removal. METHODS: A prospective, institutional database was reviewed to identify patients who underwent explantation of a failed EVAR device. Demographics, reason for failure, operative details including extent of endograft removal, and complications/survival were examined...

The Hippo pathway effector, Yes-associated protein (YAP), is a transcriptional coactivator implicated in cholangiocarcinoma (CCA) pathogenesis. YAP is known to be regulated by a serine/threonine kinase relay module (MST1/2-LATS1/2) culminating in phosphorylation of YAP at Serine 127 and cytoplasmic sequestration. However, YAP also undergoes tyrosine phosphorylation, and the role of tyrosine phosphorylation in YAP regulation remains unclear. Herein, YAP regulation by tyrosine phosphorylation was examined in human and mouse CCA cells, as well as patient-derived xenograft (PDX) models...
