Techniques in hybrid repair of aortic arch and thoracoabdominal aortic pathologies.

Introduction: Since the mid-1900s, techniques in the repair of aortic arch and thoracoabdominal aortic pathologies have drastically evolved. Open aortic surgical repair was once the sole option for both simple and complex aneurysmal degeneration. Today, a number of minimally invasive and hybrid approaches are now available to assist both the surgeon and patient in tackling this challenging problem.

Objectives: We aim to evaluate the safety and effectiveness of the Zenith Dissection Endovascular System (ZDES; Zenith TX2 Dissection Endovascular Graft with Pro-Form and Zenith Dissection Endovascular Stent), which uses a proximal stent graft along with a distal bare metal stent compared to traditional stent grafts in the repair of acute, complicated Type B Aortic Dissection (AcTBAD).
Methods: This retrospective study reviews the medical charts of 32 patients with AcTBAD repaired at a single urban academic medical center. 16 of these AcTBAD cases were repaired with the ZDES (87.

A 77-year-old male presented for an incidental 5-cm gastroduodenal artery aneurysm (GDAA). He underwent an endovascular GDAA coil embolization with 6 months of no aneurysmal growth on surveillance imaging. His 12-month scan revealed aneurysmal growth from 5 cm to 7.

Aneurysmal Coronary Artery Disease (ACAD) can occur as localized dilations of a segment of one or more coronary arteries or diffuse ectasia-type dilatations of one or more coronaries. Atherosclerosis remains the most common cause of these aneurysms, with Kawasaki Disease being implicated in the Asian population. We present a case of a 62-year-old Asian woman who dies suddenly with no prior symptoms.

Aneurysm rupture is a life-threatening event, yet its underlying mechanisms remain largely unclear. This study investigated the fracture properties of the thoracic aneurysmatic aorta (TAA) using the symmetry-constraint Compact Tension (symconCT) test and compared results to native and enzymatic-treated porcine aortas' tests. With age, the aortic stiffness increased, and tissues ruptured at lower fracture energy [Formula: see text].
