46-year-old wife (donor) and 52-year-old husband (recipient) admitted to our clinic for kidney transplantation. CT angiography of the donor showed us there were bilateral renal double artery and a tortuous aorta that is deviated to the left side. The main artery cannot be reached by laparoscopy because of the upper level of renal artery and deviation of the aorta and an open conversion was performed. Presence of tortuous aorta with multiple renal arteries makes laparoscopic donor nephrectomy a challenging procedure even preformed by an experienced surgeon. The possibility of open conversion should always be kept in mind in these cases.

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].

Background: Endovascular management of aortic arch is always demanding and challenging in type B aortic dissection (TBAD) patients. However, there is limited knowledge to understand the complex geometry of aortic arch. The aim of this study is to investigate aortic arch geometry and its potential clinical implications for endovascular planning.

Background: The syndrome of Loeys-Dietz (LDS) is a rare connective tissue disorder. A classic triad of symptoms is seen: hypertelorism, atypical uvula or clef palate, and multiple tortuous arteries and aneurysms of the aorta and main arterial branches. Mutations in genes involving the transforming growth factor-beta (TGFB) signaling pathway are the cause of this syndrome.

Endovascular procedures rely on navigating guidewires, catheters and other devices through tortuous vasculature to treat disease. A critical challenge in these procedures is catheter herniation, in which the device deviates from its intended path, often irrecoverably. To elucidate the mechanics of herniation, we developed a physical flow model of the aortic arch that enables direct measurement of device curvature during experimentally simulated neuroendovascular procedures conducted from an upper arterial access.
