BACKGROUND The most reliable data about arterial variations, which are very important in surgery and radiology, can be obtained from a large series of patients. MATERIALS AND METHODS We examined angiographic and multislice computerised tomography (MSCT) images in a group of 1,265 patients and in 1 dissected specimen. RESULTS While in 946 (74.72%) of the patients a normal vascular pattern (t...

This study reports important variations in branches of the subclavian artery in a singular cadaver. The origin of the left vertebral artery was from the aortic arch. On the right side, no thyrocervical trunk was found. The two branches which normally originate from the thyrocervical trunk had a different origin. The transverse cervical artery arose directly from the subclavian artery and supras...

Several authors have described anatomic variations of the aortic arch in 13% to 20% of the patients who do not have aortic disease. However, few studies have evaluated these patterns in the thoracic aortic dissection (TAD). In the authors' knowledge, this is the first survey that specifically investigates the frequency of these variations in a broad, nonselected group of Chinese patients with a...

Fig. 1. CTaxial image (a) evidences the anomalous origin of both carotid arteries from a unique trunk and demonstrates the presence of an aberrant right subclavian artery which passes ahead the thoracic spine inducing extrinsic compression of the esophagus. The origin of the bi-carotid trunk, which arises directly from the aortic arch, is more clearly viewable in the MPR image (b). Fig. 2. Pre-...

BACKGROUND The chimney graft (CG) technique was introduced to rescue accidentally covered aortic branches during aortic endovascular repair. It extends the sealing zone. There is concern about "gutter" type I endoleak (EL-I) and about the durability of CGs. The aim of the present report was to analyze the rapidly increasing existing data. METHODS A search was performed (PRISMA criteria) for a...

A 57-year-old Chinese male patient presented with Standford type A aortic dissection with an aberrant right subclavian artery (ARSA). At operation, the ascending aorta was replaced by a mono-branch vascular prosthesis with the branch bypassing to the ARSA; the triple-branched stent graft was inserted into the true lumen of the arch and proximal descending aorta (covering the origin of the ARSA)...

Four cases of non-specific arteritis involving the aorta and its main branches are described. Three of the cases were hypertensive and one of these had evidence of aortic incompetence. Cases 1, 2, and 3 had involvement of the aortic arch vessels and the descending aorta, whereas Case 4 presented as a coarctation of the abdominal aorta. There was a significant association with systemic disturban...

OBJECTIVES To study technical feasibility and early results of the technical modification suggested by Caliani et al. for correction of aortic coarctation and aortic arc. METHODS Between January 2005 and July 2006, nine newborn patients with aortic coarctation and significant aortic hypoplasia were selected, and underwent a new surgical approach in order to correct this aortic defect. The def...

A female newborn was referred at birth to our hospital because of respiratory distress. Her family history was unremarkable except for the first-degree consanguinity of her parents. She had a mildly dysmorphic appearance, generalized hypotonia, and several musculoskeletal features such as joint laxity, arachnodactyly, pectus excavatum, flexion contracture of the wrists, and feet anomalies (Figu...

After cervical aortic nerve section, mean arterial pressure in the unanesthetized dog increased by an average of 7.4 mm Hg. Following a more extensive denervation of aortic arch receptors by section of intrathoracic vagal branches, arterial pressure increased by 16.7 mm Hg. The above changes were seen in the stable state after the effects of surgery had disappeared. In both cases carotid barore...
