BACKGROUND: Venous aneurysms of the upper torso are uncommon in contrast to the abdomen and lower extremities. Mostly silent, they can cause significant morbidity. Large or symptomatic venous aneurysms are generally treated with open resection. To our knowledge, there are no documented cases of head and neck venous aneurysms treated by a hybrid endovascular and open approach. CASE PRESENTATION: A 56-year-old female presented with the complaint of pain and increasing size of a supraclavicular mass...

In-stent restenosis (ISR) is the most common long-term complication following Carotid Artery Stenting (CAS), affecting 3.5% to 21% of patients after a mean follow up of 18 months in published reports. Until now, the optimal management for ISR after CAS is still not clear and different endovascular treatments along with various surgical options have been proposed. Moreover, surgical treatment for ISR in a previously operated patient of ipsilateral endarterectomy is a technically demanding procedure. In this report, we describe a case of severe carotid recurrent ISR, which occurred after CAS for post-endarterectomy restenosis, that was successfully treated, in a straightforward way, with a carotid bypass using a Gore(®) Hybrid Vascular Graft...

PURPOSE: Chronic traumatism of the common femoral artery due to intravenous injection in drug abusers, in association with local infections and arterial wall weakening caused by HIV, can lead to the development of pseudoaneurysms. Rupture of pseudoaneurysm is a dramatic event in such patients and its correction is difficult and controversial. Most of the cases reported describe open surgical elective options, that consist in ligation, repair or substitution of the damaged arterial segment, employing when possible biological grafts...

Blunt subclavian artery injuries are rare and are associated with high morbidity and mortality. Several case reports have suggested that endovascular repair is safe with short operative times and minimal blood loss. We report a case of a 20-year-old male patient involved in a high speed motor vehicle collision that resulted in partial transection of left subclavian artery with complete luminal thrombosis. Patient also had a left main-stem bronchus avulsion along with major intra-abdominal injuries and multiple spine and long bone fractures...

Thoracic endovascular aortic repair (TEVAR) is an emerging treatment option for thoracic aorta aneurysms (TAA). Endovascular access is a challenge. We present a novel TEVAR technique in a patient with single kidney and a 6.4 cm TAA. Attempting to place a sheath through iliac arteries was unsuccessful. The decision to proceed to hybrid TEVAR was made. The protection of the solitary kidney was achieved through axillo-femoral bypass, followed by an end-to-side anastomosis between the aorta and a bifurcated graft...

PURPOSE: To report a hybrid technique for the treatment of a suprarenal aortic aneurysm (SAA) in a patient with iliac occlusive disease. Initially an infrarenal aorto-bifemoral surgical graft was implanted, followed by deployment of a fenestrated bifurcated stent-graft at the suprarenal part of the aorta. CASE REPORT: A 69-year old man presented with a 51-mm saccular SAA and iliac occlusive disease with intermittent claudication. Both common iliac arteries had been previously treated with kissing stents...

Aortic arch aneurysm is a complex pathology which requires coverage of one or more aortic arch vessels. In this study we explore the hemodynamic behavior of the aortic arch in aneurysmatic and treated cases with three currently available treatment approaches: Surgery Graft, hybrid Stent-Graft and chimney Stent Graft. The analysis included four models of the time-dependent fluid domains of aneurysmatic arch and of the surgery, hybrid and chimney endovascular techniques. Dimensions of the models are based on typical anatomy, and boundary conditions are based on typical physiological flow...

AIMS: The standard approach for thoracic endovascular aortic repair (TEVAR) is transfemoral; however, calcifications and tortuosity of the access vessels might be so extensive as to increase the operative risk markedly or preclude the procedure. This study evaluates the transapical approach as an alternative route for TEVAR in such patients. METHODS AND RESULTS: From June 2011 to July 2013, the institution's interdisciplinary board for aortic diseases initially denied TEVAR for eight patients with thoracic aortic pathology due to extensive calcification and tortuosity of the distal vessels...

OBJECTIVE: To study the effect of disconnected pancreatic duct syndrome (DPDS) on endoscopic management of pancreatic fluid collections (PFCs). BACKGROUND: Data on the impact of DPDS in patients undergoing endoscopic treatment of PFCs are limited. METHODS: Retrospective study of patients undergoing endoscopic drainage of PFCs from 2003 to 2015. If treatment response was suboptimal following initial endoscopic or endoscopic ultrasound-guided transmural drainage, hybrid interventions (endoscopic ultrasound-guided multigate/dual modality technique, endoscopic/percutaneous sinus tract necrosectomy) were performed...

Hybrid aortic arch repair is increasingly used for the management of aortic arch aneurysm. Pseudoaneurysm is a newly described late complication of this procedure. A 57-year-old man underwent emergent supra-aortic debranching and aortic arch stent grafting after rupture of an arch aneurysm. Three years later, the patient presented with a pseudoaneurysm at the junction between the stent graft's proximal landing zone and the origin of the debranching graft. At reoperative repair, the proximal stent graft had eroded through the aortic wall at the junction of the endograft proximal landing zone and the proximal anastomosis of the debranching graft...

Aneurysm formation and recurrent coarctation are common complications of coarctation repair, and various types of treatment have been described. Native aortic coarctation during adult life is rarer and can be responsible for severe complications. We report an original case of thoracic aortic aneurysm associated with native coarctation successfully treated by a hybrid approach, comprising retrograde implantation of a thoracic stent graft and carotid-axillary bypass graft. A large intercostal collateral was embolized with coils...

OBJECTIVES: To report our experience with intravascular and hybrid intra-operative stent placement for baffle obstruction in patients with complete transposition of the great arteries (TGA) after the atrial switch (Mustard/Senning) operation. BACKGROUND: Venous baffle obstruction is a challenging complication after atrial switch operation in patients with TGA. Traditional treatment options include intravascular stenting or surgery. METHODS: A retrospective analysis of Mayo Clinic's electronic medical record was completed to identify consecutive pediatric and adult patients with TGA after atrial switch who underwent baffle stent implantation from 1994 to 2015...

Blunt trauma to the right proximal subclavian artery is uncommon and tends to be associated with pseudoaneurysm formation. We report a patient with right proximal subclavian artery pseudoaneurysm after blunt chest trauma following a motor vehicle accident. The condition was successfully treated with a combined insertion of a covered stent and carotid-carotid bypass as a hybrid procedure. Duplex scans at 6 month and 1 year follow-up documented good stent-graft positioning and no pseudoaneurysm recurrence.

OBJECTIVE: Myocardial infarction (MI) continues to be a major burden of disease, despite rapid reperfusion interventions. Reperfusion of ischemic hearts (reperfusion injury) induces free radical generation, activation of early stress responses and apoptosis, which contributes to ventricular remodeling and dysfunction, which may lead to developing heart failure. Mineralocorticoid receptor (MR) antagonists have been shown clinically to reduce blood pressure, particularly in resistant hypertension, and substantially increase survival in heart failure...

A hybrid strategy, firstly performed in the 1990s, is a combination of tools available only in the catheterization laboratory with those available only in the operating room in order to minimize surgical morbidity and face with any cardiovascular lesion. The continuous evolution of stent technology along with the adoption of minimally invasive surgical approaches, make hybrid approaches an attractive alternative to standard surgical or transcatheter techniques for any given set of cardiovascular lesions. Examples include hybrid coronary revascularization, when an open surgical anastomosis of the left internal mammary artery to the left anterior descending coronary artery is performed along with stent implantation in non-left anterior descending coronary vessels, open heart valve surgery combined with percutaneous coronary interventions to coronary lesions, hybrid aortic arch debranching combined with endovascular grafting for thoracic aortic aneurysms, hybrid endocardial and epicardial atrial fibrillation procedures, and carotid artery stenting along with coronary artery bypass grafting...

Rapamycin is an immunosuppressive agent that is added to drug eluting stents. It prevents restenosis, but it also impairs reendothelialization. Nicorandil is a hybrid agent with adenosine triphosphated (ATP)-sensitive K+ (KATP) channel opener and nitrate properties. It prevents oxidative stress and cell apoptosis induced by rapamycin in endothelial cells in vitro. However, whether nicorandil promotes reendothelialization after angioplasty delayed by rapamycin remains to be determined. Balloon injury model was established in SD rats...
