ABSTRACT
BACKGROUND: The natural history of aneurysms ends in rupture and death. In 1990 the first endovascular exclusion of an aneurysm, using an endoluminal graft implanted through the femoral arteries was performed. More recently, the same procedure has been used for aneurysms of the thoracic aorta. AIM: To report our experience with endovascular treatment of thoracic aorta aneurysms. MATERIAL AND METHODS: Analysis of 14 patients (nine male), aged 30 to 79 years, treated between May 2001 and August 2002. RESULTS: The mean diameter of the aneurysms was 6.9 cm. The etiology was atherosclerotic in nine patients. The Excluder device (Gore) was preferentially used. There was no operative mortality or paraplegia. One patient had a transient leg monoparesis that reverted completely. No patient had type I endoleaks. Two patients had type II endoleaks on discharge, that sealed spontaneously. In a follow up, ranging from 2 to 17 months, one patient died of a bronchopneumonia and no aneurysm rupture has been detected. CONCLUSIONS: The short term results of endoluminal treatment of thoracic aorta aneurysms are excellent. This treatment is less invasive and has less complications than conventional surgery.

Se hace estudio histopatologico de musculo estriado en ratas de 3 semanas de vida, heparinizadas y sin heparina, inyectadas por via intramuscular con penicilina, cloramfenicol y NaCl9%. Se concluye que estos antibioticos son capaces de producir necrosis muscular y una reaccion intersticial secundaria, que es acentuada por la presencia de hemorragia. Se intenta extrapolar esta situacion experimental a lo que se sucede con tratamiento antibiotico intramuscular intensivo y prolongado en el recien nacido y lactante menor, que a nuestro juicio y el de los tratadistas sobre el tema seria una de la causa de la fibrosis yatrogenica del cuadriceps
