Background: Embolic stroke during arch replacement is a serious concern in patients with shaggy aorta.
Objective: To evaluate shaggy aorta in patients who received total aortic arch replacement with antegrade selective cerebral perfusion utilizing axillary perfusion.
Method: Between January 2005 and December 2010, 63 patients underwent preoperative contrast-enhanced computed tomography scanning of the aorta to evaluate atheromatous plaque. We analyzed operative data to investigate which factors were associated with outcomes and survival.
Results: Shaggy aorta was found in 34 (54%) patients. There were 3 (5%) cases in the ascending aorta, 26 (41%) in the aortic arch, and 19 (30%) in the descending aorta. Operative mortality occurred in 1 (2%) patient. Although stroke occurred in 2 (3%) shaggy aorta patients, shaggy aorta was not associated with an increased likelihood of stroke (p = 0.4951). Survival was significantly lower in patients with shaggy descending aorta (p = 0.0411) and in patients >75-years old (p = 0.0200); these traits were identified as independent risk factors for late death (p = 0.0368 and p = 0.0100, respectively).
Conclusion: We concluded that our perfusion technique protects patients with shaggy aorta against embolism, and that the survival is lower in patients with shaggy descending aorta.

Shaggy aorta is severe luminal surface degeneration of the aorta leading to an increased risk of plaque destabilization and embolization to the peripheral or visceral vessel beds. It represents a challenging clinical entity for both endovascular and open repair owing to potential atheroembolization, increased early morbidity and mortality, and poor long-term survival. Patients may be denied repair owing to its high risks.

Ascending aortic replacement is a basic procedure in aortic surgery. The crucial factor is the anastomosis method, including the anastomosis site formation. The anastomosis method is usually completely different between true aneurysms and acute aortic dissection because of the difference in the fragility of the aorta.

Shaggy aorta (SA) is characterized by a critical and extensive atheromatous disease of the thoracic and abdominal aorta. This degenerative and dangerous pathology is the result of the confluence of multiple modifiable and non-modifiable risk factors. The clinical importance of this pathology relies on the various syndromes that can develop from its etiopathogenesis, which generates great morbidity and mortality in the affected patients.

Objectives: To evaluate the blood flow velocity and wall shear stress in total arch replacement with a "shaggy" aorta, using computational fluid dynamics, and determine the optimal cannulation method.
Methods: A patient-specific aortic arch aneurysm model was constructed by using computed tomography scans. Three cannulas were assessed, as follows: dispersive with a steep angle, dispersive with a gentle angle, and the endo-hole type.
