OBJECTIVES: We sought to evaluate outcomes of stent implantation (SI) for recurrent coarctation of the aorta (RC) following the Norwood operation. BACKGROUND: RC is common following the Norwood operation. Balloon angioplasty (BA) is standard treatment but may result in unsatisfactory relief of RC. SI may improve RC, but outcome data are limited. METHODS: We performed a multi-center retrospective study of patients who underwent SI for RC between the Norwood operation and Fontan completion...

BACKGROUND AND AIM: Concomitant endovascular stent grafting of the descending thoracic aorta during open repair for acute DeBakey I aortic dissection can be performed in patients with extensive dissection and malperfusion. We analyzed the effects of this strategy on distal aortic remodeling. METHODS: From 2006-2014, acute DeBakey I dissection patients without primary aortic arch tear undergoing open distal hemiarch reconstruction (Standard group) versus those undergoing hemiarch with descending thoracic aorta (DTA) thoracic endovascular aortic repair (TEVAR group) were retrospectively reviewed...

A 74-year-old patient presented with recurrent aneurysms in the infrarenal abdominal aorta and right common iliac artery 6 years after endovascular aortic repair using endografts in the same location. The patient underwent an aorto-bi-iliac replacement with removal of the stent graft. Two holes measuring 2 mm each were found in the removed graft, and they appeared to have been caused by wear from continuous friction between the endograft and the aortic wall.

Complexity of the spatial configuration of an aortic implant with bifurcation in the distal part is related to changes in blood hemodynamic in the area of bifurcation which may disturb blood flow and lead to thrombus formation. This study was designed to characterize parameters which define spatial configuration of an aortic implant for which the risk of thrombus formation is the smallest. We used AngioCT data from 74 patients, aged 55 ±10 years, after endovascular procedure to prepare 3D geometries of stent-grafts...

Legs ischemia might be associated with acute aortic dissection, in acute phase or even in subacute phase. In general, immediate central repair for acute aortic dissection is mandatory prior to intervention of leg ischemia because central repair might improve leg ischemia. Depending on condition of leg ischemia, revascularization of occluded artery should be considered. The perfusion to ischemic leg during central repair is useful to diminish leg injury. There are some useful modalities for revascularization such as some route of extra-anatomical bypass, placing of stent graft for closing entry site of dissected aortic wall...

Visceral artery revascularisation through a retroperitoneal approach provides an infrequent yet viable, alternative means of managing mesenteric ischaemia in patients with previous abdominal operations. We present a unique case implementing this surgical approach in a 55-year-old man in which we performed a retroperitoneal aortobifemoral bypass with concomitant retrograde jump graft from the aortic prosthesis to the superior mesenteric artery (SMA) for bilateral lower extremity rest pain and chronic mesenteric ischaemia...

INTRODUCTION: Neck enlargement is well described in patients treated with self-expandable endografts for abdominal aortic aneurysms. Double endografting (ie, overlapping of stent grafts) occurs in patients with proximal cuffs or bifurcated to monoiliacal configuration conversions. When the aortic neck of patients receives 2 suprarenal fixation endografts, it may behave differently in terms of radial force and interaction of additional suprarenal stents extending to the visceral aorta...

BACKGROUND: Previous studies comparing endografts with suprarenal and infrarenal fixation for endovascular abdominal aortic aneurysm repair (EVAR) have found conflicting results and did not account for differences in patient selection. This study aims to evaluate the differences in outcomes among surgeons who routinely use either suprarenal or infrarenal fixation, as well as all surgeons in the Vascular Study Group of New England (VSGNE). METHODS: All patients undergoing EVAR in the VSGNE from 2003 to 2014 were identified...

Transradial access has been described in a variety of clinical contexts but has been rarely utilized for visceral artery interventions and during complex endovascular aortic aneurysm repair (EVAR) when upper extremity access is required. This is usually accomplished via brachial artery access, and although brachial access is generally safe and effective, radial access may offer some benefits with regard to patient comfort and potential complications. Here we report a case of successful delivery of a renal snorkel via a radial artery approach during EVAR...

PURPOSE: To describe the technical aspects of a thoracoabdominal aortic aneurysm (TAAA) repair using a patient-specific fenestrated-branched stent-graft. TECHNIQUE: The technique is demonstrated in a 69-year-old man with a 6.2-cm asymptomatic type III TAAA. A patient-specific fenestrated-branched stent-graft was designed with 2 down-going directional branches for the celiac and superior mesenteric arteries and 2 reinforced fenestrations for the renal arteries. The procedure was performed under general anesthesia and included sequential stenting of the celiac, superior mesenteric, and bilateral renal arteries...

OVERVIEW: To describe a new endovascular procedure for acute type A aortic dissection (TAAD) repair. METHODS: Between 2013 and 2016, 12 patients (average age 54±9.6 years; 10 men) with acute TAAD (mean EURO score 11.4%±3.2%, range 5-17) and unfit for surgery underwent thoracic endovascular aortic repair (TEVAR) with 2 periscope grafts to preserve blood supply to supra-aortic branches plus bypass grafting as needed. If the ascending aorta was dilated to >40 mm, sternotomy was performed to wrap the ascending aorta and reduce its diameter to accommodate the aortic stent-grafts...

We evaluated the effects of changes in blood flow due to abdominal aortic aneurysm (AAA) surgery by using a simple zero-dimension model and applied theoretical values to clinical data.The zero-dimension electronic circuit model and diagram of blood flow distribution were created by setting the resistance of the aorta, bilateral iliac arteries, renal arteries, and aneurysm. Resistance of the aneurysm and resistance of the aorta before surgery were compared with that of the aorta after surgery. We set the radius length of each anatomical parameter to calculate theoretical values...

OBJECTIVE: By using a guidewire fixator, the distal guidewire position can be secured in an artery. This new principle enables a method for fenestrated endovascular aortic repair where the connection between the aortic branches and the stent graft fenestrations is made before inserting and deploying the stent graft. METHODS: This is conducted using a fenestrated stent graft with preloaded catheters, through which the prepositioned and distally secured guidewires from the branches are inserted...

OBJECTIVE: We studied short-term and long-term effects of covered stent endovascular graft exclusion for the treatment of abdominal aortic aneurysm rupture. PATIENTS AND METHODS: From January 2013 to January 2016, 88 patients with fractured abdominal aortic aneurysm were enrolled in this study. Patients were divided into the control group or the open abdomen group (n=52) and the observation group or the isolated group (n=36). Patients in the control group were treated with open abdominal aneurysm resection and artificial blood vessel transplant technique, while patients in the observation group were treated with percutaneous stent graft endovascular graft exclusion...

BACKGROUND: Thoracic Endovascular Aortic Repair (TEVAR) has substantially decreased the mortality and major complications from aortic surgery. However, neurological complications such as spinal cord ischemia may still occur after TEVAR. S-100β is a biomarker of central nervous system injury, and oxidant injury plays an important role in neurological injury. In this pilot study, we examined the trends of S-100β and antioxidant capacity in the CSF during and after TEVAR. METHODS: We recruited 10 patients who underwent elective TEVAR...
