MORA O, RENÉ et al. Atherosclerotic aneurysm of the superficial temporal artery. Report of one case. Rev Chil Cir [online]. 2008, vol.60, n.5, pp. 429-433. ISSN 0718-4026. http://dx.doi.org/10.4067/S0718-40262008000500011.
Superficial temporal artery aneurysms (STAA) are an uncommon condition. Only 14 atherosclerotic STAA had been reported. This contrasts with almost 400 cases of superficial temporal artery traumatic pseudoaneurysms reported. We report a 66 years oíd female with hypertension treated for 17 years. She consulted for a painless pulsatile mass on the right temporal región lasting 14 months. A Doppler vascular ultrasound, described a superficial temporal arteryfusiformaneurysmof 2 cmdiameterand 3 cm length. The surgical exploration revealed the presence of the aneurysm compromising the superficial temporal artery. Simple dissection and resection of the lesión, ligating all the involved vascular branches was performed. The histopathological study reported involvementof allthree layersofthe vascular wallovertheaneurysmatic área, also reported the presence of atherosclerotic adventitial vessels and atherosclerotic thickening of the intima. The Van Gieson stain for elastic fibers demonstrated integrity of the internal elastic layer.
