Aortic root aneurysm extending into the arch as a rare complication of Kawasaki disease: surgical management.

An aortic aneurysm complicating Kawasaki disease (KD) is extremely rare. We herein report a case of 48-year-old KD patient with severe aortic regurgitation, aneurysm of the aortic root, ascending aorta and aortic arch, and giant heavily calcified coronary aneurysms. The patient underwent successful surgical management.

WILIS IRLE ARITINS, IMPORTANT FOR CEREBRAL PROTECTION IN AORTIC SURGERY - PRIMARY CT ANGIO DATA.

Unilateral selective cerebral perfusion (SCP) is a method for cerebral protection in aortic arch surgery. However variations of the circle of Willis (CoW) could vitiate its protective effect. The aim of our present work was to make a retrospective analysis of 30 patients, in whom CT angio was performed between January and March 2008.

The role of Willis circle variations during unilateral selective cerebral perfusion: a study of 500 circles.

Objectives: During unilateral selective cerebral perfusion (uSCP), with right axillary artery or brachiocephalic trunk cannulation, the brain receives blood only via the right common carotid artery and right vertebral artery (VA). The left hemisphere is perfused mainly through the circle of Willis (CW). However, at least 50% of individuals have some variation in the CW.

Light and electron-microscopic study of leucine enkephalin immunoreactivity in the cat claustrum.

The claustrum is a complex telencephalic structure owing to its reciprocal connectivity with most--if not all--cortical areas. However, there is a paucity of data in the literature concerning its histochemical components, including opioid peptide neurotransmitters. The aim of the present study was to examine the morphology, distribution and ultrastructure of leucine-enkephalin-immunoreactive (Leu-enk-ir) neurons and fibers in the dorsal claustrum (DC) of the cat.

Neuronal nitric oxide synthase immunopositive neurons in cat claustrum--a light and electron microscopic study.

Nitric oxide is a unique neurotransmitter, which participates in many physiological and pathological processes in the organism. Nevertheless there are little data about the neuronal Nitric Oxide Synthase immunoreactive (nNOS-ir) neurons and fibers in the dorsal claustrum (DC) of a cat. In this respect the aims of this study were: (1) to demonstrate nNOS-ir in the neurons and fibers of the DC; (2) to describe their light microscopic morphology and distribution; (3) to investigate and analyze the ultrastructure of the nNOS-ir neurons, fibers and synaptic terminals; (4) to verify whether the nNOS-ir neurons consist a specific subpopulation of claustral neurons; (5) to verify whether the nNOS-ir neurons have a specific pattern of organization throughout the DC.
