OBJECTIVE: Despite technical advances of fenestrated and branched endografts, endovascular exclusion of aneurysms involving renal, visceral, and/or supra-aortic branches remains a challenge. In situ fenestration (ISF) of standard endografts represents another endovascular means to maintain perfusion to such branches. This study aimed to review current indications, technical descriptions, and results of ISF. METHOD: A review of the English language literature was performed in Medline databases, Cochrane Database, Web of Science, and Scopus using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines...

BACKGROUND: This study assessed the early and long-term results of arch operations performed after a prior aortic operation. METHODS: From 1994 to 2014, 154 consecutive patients (mean age, 59.7 years) underwent an aortic arch repair, after a previous aortic operation, at our institution. Antegrade selective cerebral perfusion was used in all cases. Chronic postdissection aortic aneurysm (87 [56.5%]) and degenerative aneurysm (43 [27.9%]) represented the most common indications for surgical intervention...

Neurologic injuries following aortic arch operations can be devastating, with stroke occurring in up to 12% of elective operations and significant cerebral dysfunction occurring in up to 25% of cases. The primary challenge unique to aortic arch operations involves interruption of direct perfusion of the brachiocephalic vessels during arch reconstruction. For this reason, neuroprotection is paramount. The 2 main modes of protection are (1) reducing metabolic demand through hypothermia and (2) limiting, or even eliminating, the ischemic period...

BACKGROUND: Patients undergoing hybrid aortic arch reconstruction require careful protection of vital organs. We believe that whole body perfusion with tailored dual circuitry may help to achieve optimal patient outcomes. METHODS: Our circuit has evolved from a secondary circuit utilizing a cardioplegia delivery device for lower body perfusion to a dual-oxygenator circuit. This allows individually controlled regional perfusion with ease of switching from secondary to primary circuit for total body flow...

We review the operative techniques of aortic arch replacement. Aortic arch replacement presents several formidable challenges, as it requires arresting the circulation to the body and replacement of the brachiocephalic vessels with special consideration for protecting the central nervous system. Perfusion strategies, selective antegrade cerebral perfusion, and operative graft selection are key elements in aortic arch replacement surgery. Standard approaches include the island technique, the branched graft technique, and the "Spielvogel" trifurcated graft technique-each having its own advantages...

OBJECTIVE: The optimal strategy to deliver antegrade cerebral perfusion for cerebral protection during hypothermic circulatory arrest has not been established. The purpose of this review was to present our current clinical protocol utilizing selective antegrade cerebral perfusion during aortic arch surgery and to compare it to other published experience. CLINICAL PROTOCOL: Since 2013, our clinical protocol for aortic arch surgery has evolved to using selective antegrade cerebral perfusion via the innominate artery, moderate hypothermia, and ancillary strategies such as goal-directed perfusion (GDP)...

Many known risk factors for adverse cardiovascular and neurological outcomes in children with congenital heart defects (CHD) are not modifiable; however, the temperature and blood flow during cardiopulmonary bypass (CPB), are two risk factors, which may be altered in an attempt to improve long-term neurological outcomes. Deep hypothermic circulatory arrest, traditionally used for aortic arch repair, has been associated with short-term and long-term neurologic sequelae. Therefore, there is a rising interest in using moderate hypothermia with selective antegrade cerebral blood flow on CPB during aortic arch repair...

Open aortic arch replacement is a complex and challenging procedure, especially in post dissection aneurysms and in redo procedures after previous surgery of the ascending aorta or aortic root. We report our experience with the simultaneous selective perfusion of heart, brain, and remaining body to ensure optimal perfusion and to minimize perfusion-related risks during these procedures. We used a specially configured heart-lung machine with a centrifugal pump as arterial pump and an additional roller pump for the selective cerebral perfusion...

The key to aortic surgery is protection of the brain, heart, spinal cord, and viscera. For operations involving the aortic arch, the focus is on cerebral protection, while for pathology involving the descending thoracic aorta, the focus is on spinal protection. Optimal cerebral and spinal protection requires an extensive knowledge of the operative steps and an understanding of the cardiopulmonary bypass modalities that are possible. A bloodless field is required when operating on the aorta. As a result, periods of ischemia to the central nervous system and end-organ viscera are often unavoidable...

Open aortic arch surgery after coronary artery bypass grafting (CABG) is considered a high-risk operation. We reviewed our surgical approach and outcomes to establish the risk profile for this patient population. In methods, from 2000-2014, 650 patients underwent aortic arch surgery with circulatory arrest. Of these, 45 (7%) had previous CABG. Complete medical record was available for review including all preoperative coronary angiograms and detailed management of myocardial protection. In results, the mean interval from previous CABG to aortic arch surgery was 6...

Hypothermic circulatory arrest is a critical component of aortic arch procedures, without which these operations could not be safely performed. Despite the use of hypothermia as a protective adjunct for organ preservation, aortic arch surgery remains complex and is associated with numerous complications despite years of surgical advancement. Deep hypothermic circulatory arrest affords the surgeon a safe period of time to perform the arch reconstruction, but this interruption of perfusion comes at a high clinical cost: stroke, paraplegia, and organ dysfunction are all potential-associated complications...

PURPOSE: Selective antegrade cerebral perfusion (SACP) involving cannulation of either the axillary or innominate artery is a commonly used technique for maintaining cerebral blood flow (CBF) during the use of hypothermic cardiac arrest (HCA) for operations on the aortic arch. Nevertheless, asymmetrical CBF with hypoperfusion of the left cerebral hemisphere is a common occurrence during SACP. The purpose of this report is to describe an adjunctive maneuver to improve left hemispheric CBF during SACP by applying extrinsic compression to the left carotid artery...

OBJECTIVES: Operating on the aortic arch is a surgical challenge involving various periods of circulatory arrest. Deep hypothermia is used to protect the brain. Selective antegrade cerebral perfusion (SACP) is employed to protect the brain and enable cerebral ischaemia time to be prolonged. However, there is no standardized SACP protocol. Our centre has performed flow- and pressure-controlled bilateral antegrade cerebral perfusion since 1999. The aim of this study was to investigate the potential relationship between perfusion pressure and neurological outcome, and to examine whether the selective application of higher cerebral perfusion pressure results in better neurological outcomes...
