Description

The supra-aortic trunks and the most critical visceral branches of the abdominal aorta (celiac trunk, superior mesenteric artery, and renal arteries) are responsible for the blood supply to the head, neck, superior limbs, and abdominal viscera. The atherosclerotic degeneration of those vessels or branches could eventually lead to a significant decrease in the blood flow to vital structures. That is the main reason why those arteries are currently common sites of endovascular manipulation. The knowledge about the resistance of these vessels' walls and their compliance is beneficial for the doctors who manipulate them and the industries that produce endovascular devices. The present dataset is a collection of uniaxial biomechanical tests from arteries harvested during the autopsy procedure of 27 adult donors. Samples from the brachiocephalic trunk, left common carotid artery1, left subclavian artery, celiac trunk, superior mesenteric artery, and renal arteries were collected for analysis whenever it was possible. A 2 cm long segment of each artery was collected and longitudinally opened to produce a flat tissue sample. Like the standardization used for aorta fragments previously published in literature2, the uniaxial tensile test utilized the INSTRON SPEC 2200 device and was coordinated by INSPEC software and SERIES IX software. The essential variables studied through this test are failure stress, failure tension, and failure strain. Each sample test generated a graph representing the relationship between stress and strain (elastic diagram). Notable findings: Although much smaller and seaming much more delicate than the aorta itself, some of its branches showed values of stress and tension higher than the ones observed in aorta fragments previously published in the literature by Monteiro and Nynomiya.3,4 DATA DESCRIPTION: Biomechanical Data: For each valid sample test, three documents were generated: 1. Stress X strain graph (all graphs contain a notification in their left upper corner about each sample's failure stress, strain (also called ultimate yield in the charts), and tension). 2. Table (excel file containing all the values related to the stress X strain graph) 3. A report from the Biomechanical test software containing details of the test All files related to valid biomechanical tests from these 27 cadaveric donors' arteries were included in the present dataset. Unfortunately, some of the tensile tests were not considered valid as the samples slipped from the biomechanical test equipment clips. Therefore, only valid tests are present in this dataset.
