Several studies have suggested that surgical procedures performed at high-volume centers may result in superior outcome. Technically more demanding procedures such as aortic aneurysm repair appear to demonstrate a stronger relationship with volume. The present chapter reviewed the literature using the MEDLINE database to identify studies investigating the effect of volume in aortic aneurysm repair outcomes. The great majority of studies identified shows an advantage for high-volume hospitals with regard to perioperative mortality of abdominal (AAA), thoracic (TAA) and thoracoabdominal (TAAA) aortic aneurysm repair...

OBJECTIVE: Alloplastic aortic graft infection is a devastating complication following aortic surgery. It is associated with excessively high mortality and morbidity caused by anastomotic rupture or septicemia. Many authors consider in situ replacement after complete surgical graft removal as the method of choice. However, there is an ongoing debate about the most suitable material for reconstruction. We present our first experiences with replacing the descending and infra-renal aorta using custom-made bovine pericardium grafts...

BACKGROUND: Endovascular aneurysm repair (EVAR) and Thoracic endovascular aortic repair (TEVAR) are commonly performed by interventional radiologists, cardiologists, general surgeons, cardiothoracic surgeons, and vascular surgeons, with each specialty having differences in residency structure, operative experience, and subspecialty training. The aim of this study is to evaluate the impact of surgeon specialty on outcomes following EVAR and TEVAR. METHODS: Patients who underwent EVAR and TEVAR were identified from the 2007 to 2009 Nationwide Inpatient Sample (NIS)...

Successful endovascular aortic repair is highly dependent on the quality of the iliac access vessels. Patients with poor access vessels can be turned down from endovascular aortic repair or thoracic endovascular aortic repair by the treating physician. Perioperative complications such as failure to deliver the device or iliac rupture can be addressed to improper access vessels. In this article, we describe a novel technique to access the common iliac artery when access vessels are poor in diameter or quality...

Endovascular abdominal aortic aneurysm repair (EVAR) and thoracic aortic aneurysm repair (TEVAR) have been widely incorporated into clinical practice. However, changes in arterial stiffness and post-implantation syndrome after aortic endografting remain important issues under investigation. The aneurysm sac wall motion after successful EVAR and TEVAR reflects complex interactions between all the components of the excluded aneurysm, including true compliance of the aneurysm wall itself, intra-aneurysm sac pressure, remodeling of the thrombus, and mechanical characteristics of the endograft...

In recent years, aortic aneurysm treatment with stent graft grafting in the X-ray fluoroscopy is increasing. This is an endovascular therapy, because it is a treatment which includes the risk of radiation damage, having to deal with radiation damage, to know in advance is important. In this study, in order to grasp the trend of exposure stent graft implantation in a hybrid operating room (OR) system, focusing on clinical data (entrance skin dose and fluoroscopy time), was to count the total. In TEVAR and EVAR, fluoroscopy time became 13...

The patient with thoracic aortic disease can present for open or endovascular repair. Thoracic endovascular aortic repair (TEVAR) has emerged as a minimally invasive option for a multitude of aortic pathology, including dissections, aneurysms, traumatic injuries, and ulcers. Postoperative management of these patients depends on the extent of procedure, whether it was open or endovascular, and, finally, on the preoperative comorbidities present. While procedural success has catapulted TEVAR to popularity, midterm results have been mixed...

The axillary artery approach has been used for access for complex endovascular aortic procedures such as thoracic endovascular aortic repair with poor anatomy for traditional deployment as well as for fenestrated and branched abdominal aortic endografts. We report the first case of an iliac graft limb deployment through the axillary artery during an endovascular aortic repair for maintenance of anterograde internal iliac flow in a patient with a symptomatic abdominal aortic aneurysm and chronic occlusion of both the external iliac and common femoral arteries...

Endovascular procedures, such as transcatheter aortic valve implantation (TAVI), thoracic endovascular aortic repair (TEVAR), and endovascular abdominal aortic repair (EVAR) have been established as promising less invasive therapeutic options. However, despite continuous advances and device improvements, the use of large-sheaths still remains an important challenge, since significant coexisting arterial disease may be encountered in patients undergoing such procedures. Identification of coexisting arterial diseases by optimal preoperative imaging assessment is essential to anticipate these difficulties and avoid the complications by using adequate access options...

BACKGROUND: The chimney graft (CG) technique was introduced to rescue accidentally covered aortic branches during aortic endovascular repair. It extends the sealing zone. There is concern about "gutter" type I endoleak (EL-I) and about the durability of CGs. The aim of the present report was to analyze the rapidly increasing existing data. METHODS: A search was performed (PRISMA criteria) for all studies of visceral and thoracic/arch chimney grafts. Technical and clinical details and outcome were assessed...

OBJECTIVE: Thoracic endovascular aneurysm repair (TEVAR) for the aortic arch aneurysm is challenging because of its curved anatomic configuration and the presence of the supra-aortic branches. The Najuta fenestrated endograft (Kawasumi Laboratories, Inc, Tokyo, Japan) was developed to treat aortic arch diseases, offering maximal proximal landing length while preserving the blood flow to the supra-aortic branches. We evaluated the perioperative and midterm outcomes of this fenestrated endograft...

We report the management of a patient who had an open-surgical repair following traumatic avulsion of the supra-aortic trunks (SAT) 30 years prior to presentation with a large arch aneurysm and poor cerebral collaterals. "Simple" thoracic endovascular aneurysm repair (TEVAR) was not an option because it would have excluded the collateral circulation to the carotid and vertebral arteries. We devised a two-stage hybrid procedure to repair this challenging aneurysm.

The approach to aortic pathology is nowadays more and more endovascular at both thoracic and abdominal levels. Thoracic stenting has gained worldwide acceptance as first intention to treat pathologies of the descending thoracic aorta. Indications have been extended to aortic arch aneurysms and also to diseases of the ascending aorta. The current devices in use for thoracic endovascular repair (TEVAR) are Medtronic Valiant, Gore TAG, Cook Tx2 and Jotec. The choice of the endograft depends on the thoracic aortic pathology and the anatomical suitability...
