The thoracic aorta is involved in 30% to 40% of cases. Within the thoracic area, the anatomic distribution is as follows: 45% involve the ascending aorta, 35% involve the descending thoracic aorta, 10% involve the aortic arch, and 10% involve both the thoracic and abdominal aorta. The mosaic tissue-engineered porcine pulmonary artery valved conduits were successfully implanted in 12 sheep. One sheep died after 93 days because of atelectasis, but the remaining 11 sheep survived until 12 months. The sheep weights were significantly higher than the preoperative weights ( ± vs ± kg, P Author: Zhiwei Xu, Zhiwei Xu, Yan Tan, Juyi Wan, Hao Wu, Da Gong, Qiuxia Shi, Zifan Zhou, Xiufang Xu, Wenbin.

Sternal artery (or internal mammary), from the ventral side of the subclavian, supplies the ventral body wall. Costocervical axis, branch from the sub- clavian just opposite the first rib. It later branches into two arteries supplying the back and neck. Thyrocervical axis, arises from the subclavian below the first rib. Its branches supply the neck and shoulder. Using a clean pair of scissors and forceps, remove sections of the aorta, about 5cm x 2cm (depending on the size of the aorta), being careful not to remove the area with the intercostal vessels. 7. Place the strips in a petri dish until ready to separate the layers.

The intercostal arteries are a group of arteries that supply the area between the ribs ("costae"), called the intercostal highest intercostal artery (supreme intercostal artery or superior intercostal artery) is an artery in the human body that usually gives rise to the first and second posterior intercostal arteries, which supply blood to their corresponding intercostal es: Intercostal muscles and intercostal space.
Unpaired Visceral Artery of the Abdominal Aorta-the first major branch of the abdominal aorta-branches from the aorta around the level of the T12 vertebra-one of three anterior/ midline branches of the abdominal aorta (the others are the superior and inferior mesenteric arteries).
In this work, we determined whether the acellular intima from porcine thoracic aorta can be a new kind of xenograft to repair the skin-wound surface in a rat model. Acellular intima xenografts (AIX) were prepared from tunica intima, and then the swelling ratio, moisture content ratio, water retention ratio, degradation rate, and water vapor Cited by: 5.

Other articles where Thoracic aorta is discussed: connective tissue disease: Necrotizing vasculitides: the aorta, involves principally the thoracic aorta (chest portion) and the adjacent segments of its large branches.
Symptoms, including diminished or absent pulses in the arms, are related to narrowing and obstruction of these vessels. A common trunk of the posterior intercostal arteries originating from the descending thoracic aorta is normally an anatomical variation.
A search through the literature disclosed the frequencies of common trunks variations among population, but no information relates to particular topic of simultaneous multiple common trunks of the PIA present in Cited by: 1. Introduction.
The thoracic aorta is a large elastic artery with functionality beyond a static, passive conduit. 1 Functions of the aorta include regulating systolic blood pressure by accepting the ejection bolus through expansion and maintaining diastolic blood pressure by dynamic, elastic recoil.
1–2 Consequently, normal functioning of the aorta requires consistent passive and Cited by: Composed of two coxal bones that articulate with each other anteriorly and with the sacrum posteriorly.
It performs three functions: it bears the weight of the body; it serves as a place of attachment for the legs; and it protects the organs located in the pelvic cavity, including the urinary bladder and the reproductive organs.
In vitro hemodynamic characteristics of tissue bioprostheses in the aortic position. Yoganathan AP, Woo YR, Sung HW, Williams FP, Franch RH, Jones M.
The in vitro hemodynamic characteristics of a variety of old and new generation porcine and bovine pericardial bioprostheses were investigated in the aortic position under pulsatile flow by: The thoracic wall or chest wall is a musculoskeletal structure that has a vast vascular supply.
Most of the arteries of the thoracic cavity arise directly from the thoracic aorta; while others arise from its the other hand, the veins of the thoracic wall eventually coalesce to drain into the vena caval system.

The atherosclerotic lesions of the descending aorta were scored from 0 (no atherosclerosis) to 3 (plaque >5 mm and/or "complex" plaque with ulcerated or mobile parts). Atherosclerosis was observed in patients, (grade 3 in 16, and grade 2 in 86 patients) whereas patients only had an intimal thickening or normal intimal by: CURRENT REVIEW Pressure-Induced Arterial Wall Stress and Atherosclerosis Mano J.

Intercostal muscle flaps were used with rabbits to reconstruct full thickness defects of thoracic aorta and the auricle of the atrium of the heart.
Repair was achieved by the muscle flap, which provided good structural support with formation of elastic tissue and : Ch. Papp, G. Klima, J. McCraw.
