Objective(s): Paraplegia is deterioration in motor or sensory function of the lower limbs that can occur after modification of a thoracoabdominal aortic aneurysm. The purpose of this survey was to determine the protective action of lutein on spinal cord ischemia-reperfusion (I-R) damage. Materials and Methods: Thirty-five male rats were distributed into five groups: intact, sham, dimethyl sulfo...

20-Hydroxyeicosatetraenoic acid (20-HETE), a potent vasoconstrictor and mediator of the myogenic response, is a major arachidonic acid metabolite in the microvasculature of the rat kidney formed primarily by the cytochrome P-450 (CYP) 4A isoforms, CYP4A1, CYP4A2, and CYP4A3. We examined CYP4A isoform expression and 20-HETE synthesis in microdissected interlobar, arcuate, and interlobular arteri...

Cystic medial necrosis is a disorder of large arteries, particularly the thoracic aorta, characterized by an accumulation basophilic ground substance in media with cyst-like lesions. A male his late 20s was brought to our trauma bay after he met road traffic accident complaint abdominal pain. Clinical examination revealed tenderness left lumbar region. The contrast-enhanced computerized tomogra...

Abstract The renal arteries arise from the lateral side of abdominal aorta at L2 vertebral level, just below origin superior mesenteric artery. Multiple aberrant can pose difficulties in transplantation, interventional radiological and urological procedures, artery embolization, angioplasty, or vascular reconstruction for congenital acquired lesions. We present a case left kidney supplied by al...

Objetivo: Demostrar que el tratamiento endovascular es la mejor opción terapéutica en pacientes con aneurisma de aorta abdominal y riñón herradura. Además revisar estas patologías asociadas son poco frecuentes, encontrándose 0.12 % los tratados. Esta asociación incrementa dificultad técnica reparación abierta. Descripción del caso: Se analiza a una paciente femenina adulta mayor acude centro pa...

OBJECTIVES This research aims to study how carotid atherosclerosis is related to growth of infrarenal aortic diameter and aneurysmal formation. DESIGN Population-based follow-up study. MATERIALS AND METHODS At baseline, ultrasound examination of the carotid artery and the abdominal aorta was performed in 4241 persons from a general population with no evidence of abdominal aortic aneurysm (A...

A n abdominal aortic aneurysm (AAA) consists of a localized dilation of the aorta, with an increase in diameter of at least 50%.1 Most AAAs are located in the infrarenal region. Their prevalence has increased 300% in the past 30 years (between 3% and 6% in men over 65 years of age and 10% in men over 70). The increased prevalence of this condition and the aging population have elevated the cost...

A giant aneurysm of the abdominal aorta presented with a 2-3 h history of right loin pain radiating to the groin and was associated with microscopic haematuria. The pain settled and a urogram was performed 2 days later. Considerable calcification in its wall outlined a very large aneurysm of the abdominal aorta with a maximum transverse diameter of 13.5 cm. The patient underwent successful emer...
