[Large infectious thoracoabdominal aortic aneurysm in a chronic contained rupture, treated successfully using the "simplified technique"].

The clinical case of a 72-years old male is reported, admitted into a Medical Department through the Emergency Service, with a clinical picture of heavy lumbar pain, with walking compromise and acute urinary retention, lasting for several hours. Laboratory analysis revealed a marked elevation of acute inflammatory parameters and a renal failure, expressed by 108 mg/dl of urea and 4.4 mg/dl of creatinine. The patient was admitted with the provisional diagnosis of acute prostatitis, pos-renal acute renal insufficiency and dorso-lumbar pathology of unknown etiology. Three consecutive and subsequent hemocultures allowed the isolation of a Streptococcus pneumonae strain and a CT dorso lumbar spine evaluation disclosed a D11 to D12 spondylodiscitis, with a partial destruction of the vertebral bodies and an extensive throracoabdominal aortic aneurysm adjacent to those vertebrae, with some characteristic features of an infectious aneurysm. Simultaneously, an hemothorax on the left chest was noticed, consequence of a chronic contained rupture of the aneurysm. Following an intensive and specific antibiotic therapy and with an almost completed recovery of the renal function, he underwent surgical management, consisting in the evacuation and drainage of the hemothorax, followed by resection of the aneurysm and extensive tissular debridmente, culminating in the vascular reconstruction utilizing the "simplified technique", introduced in 1984 by A. Dinis da Gama for the surgical management of thoracoabdominal aortic aneurysms. The patiente tolerated the procedure well, with no intercorrences or complications and the post operative course was unventfull. One month later, a CT-angio control disclosed the revascularization procedure working in excellent condition. Finally, an orthopedic artrodhesis of the injuried vertebrae was performed, allowing an easy and pain-free walking and he was discharged on day 60, under antibiotic treatment. The main features of this clinical case are emphasized and discussed, namely those aspects related to its pathogenesis, clinical presentation, diagnosis and surgical management.
