Purpose: To report implantation of an iliac branch device (IBD) for preserving antegrade blood flow to a sole internal iliac artery (IIA) via an ipsilateral approach during endovascular repair to reline an aortobi-iliac allograft.

Technique: The technique is described in a 55-year-old man with an enteric fistula involving an aortobi-iliac Y-prosthesis. After complete excision, the prosthesis was replaced by an allograft.

Branched versus fenestrated endografts for endovascular repair of aortic arch lesions.

Objective: Endovascular repair of the aortic arch represents a formidable challenge because of aortic diameter, angulation, elasticity, and greater distance to the femoral access vessels. Whereas both fenestrated and branched endografts have been customized to accommodate complex pathologic processes of the arch, no data comparing the techniques are available. The aim of this study was to compare the outcomes of custom-made fenestrated vs branched thoracic endovascular aortic repair (fTEVAR vs bTEVAR).

Complete Antegrade Transapical Deployment of a Branched Aortic Arch Endograft: A Porcine Feasibility Study.

Purpose: To describe and prove the concept of a technique for complete transapical deployment of a single-branch aortic arch endograft in a porcine model.

Methods: Eight domestic pigs underwent antegrade transapical delivery of a single-branch arch endograft, including a mating stent-graft to the innominate artery. Technical feasibility, operating time, radiation parameters, and hemodynamic changes were studied according to a standardized protocol during baseline (T0), after establishing the transapical access and through-and-through wire (T1), and after stent-graft deployment (T2).

Early outcomes and perioperative risk assessment in elective open thoracoabdominal aortic aneurysm repair: An analysis of national data over a five-year period.

Open surgical repair of thoracoabdominal aortic aneurysms remains associated with significant morbidity and mortality. We sought to analyse multicentre national data on early outcomes of open surgical thoracoabdominal aortic aneurysm repair. Patients who underwent open repair of thoracoabdominal aortic aneurysm from 2005 to 2010 were identified from the National Surgical Quality Improvement Program database.

Chronic type B aortic dissection: indications and strategies for treatment.

Chronic type B aortic dissection is a distinctive condition that needs individual treatment strategies and different considerations than in therapy of acute or subacute type B aortic dissection. The most common indication for treatment of this complex disease is aneurysmal dilatation of the dissected aortic segment. While open repair of the enlarged dissected aorta remains the best option for good-risk patients and patients with connective tissue disorders in high-volume centers with respective expertise, endovascular management of chronic type B aortic dissection with postdissection aneurysms has significantly gained ground in the past years.

[Transcardiac Access Routes for Endovascular Treatment of Ascending Aortic Pathologies].

Gold standard for treatment of pathologies of the ascending aorta is still open surgery with extracorporal circulation in moderate to deep hypothermia. These procedures are associated with high morbidity and mortality, especially if performed in older patients or after previous cardiac surgery. Thoracic endovascular aortic repair (TEVAR) has become the preferred treatment option for thoracic aortic pathologies of the descending aorta even in high-risk patients with severe comorbidities resulting in reduced morbidity and mortality compared to open repair.

Proximal thoracic endograft displacement rescued by balloon-assisted pull-back, external shunting, and in situ fenestration of the left carotid artery.

Proximal displacement of thoracic aortic endografts is a catastrophic adverse event, which rarely occurs but is associated with extremely high morbidity and mortality. We describe herein the case of a patient with accidental proximal displacement of a thoracic endograft with occlusion of all supra-aortic branches, successfully rescued by the combination of three advanced endovascular techniques: (1) aggressive pull-back maneuver with a compliant balloon; (2) establishment of an arterio-arterial temporary shunt to the occluded carotid artery over sheaths; and (3) in-situ fenestration of the occluded carotid artery.

TEVAR for chronic aortic dissection - is covering the primary entry tear enough?

Treatment-strategies for type B aortic dissection (TBAD) are rapidly developing towards endovascular treatment strategies. While TEVAR for acute TBAD shows favourable results, TEVAR in chronic TBAD following the same interventional strategies as in acute TBAD by covering the proximal entry-tear alone has shown unsatisfactory results with one third of the patients developing further false-lumen growth and mortality of 36% at 3 years. This review article describes endovascular strategies and adjunctive techniques to prevent distal false-lumen back-flow in patients with chronic TBAD, as covering the proximal entry tear has proven insufficient.

Acute aortic syndromes: definition, prognosis and treatment options.

Acute aortic syndromes (AAS) are life-threatening vascular conditions of the thoracic aorta presenting with acute pain as the leading symptom in most cases. The incidence is approximately 3-5/100,000 in western countries with increase during the past decades. Clinical suspicion for AAS requires immediate confirmation with advanced imaging modalities.
