[Mycotic aneurysms of the thoraco-abdominal part of the aorta]

Mycotoc aneurysms (MA)--a rare and extremely dangerous lesion of the aorta. CT, MRA and aortography were used to diagnose MA of the thoracoabdominal areas in 2 men of 64 and 67 years of age. The clinical picture included: fever with shivering with the temperature 38-39 degrees C and increasing pains in the inferiothoracic and lumbar areas of the spine. Hemoculture was positive in 1 patient only. The patients were operated on. Shunting of the aorta from the inferiothoracic to infrarenal segments was performed in one patient with the exclusion of the involved portion and resection of MA. Metalloosteosynthesis of the spine due to destruction of LI-LII and compression of the spine were performed in the second patient followed by analogous shunting of the aorta and visceral arteries with the resection of the aneurysm. To prevent infection of the prostheses the shunts were wrapped up with a piece of the greater omentum. One patient died two months later from recurrent sepsis. The other one is alive, within 28 months the shunts are patent, there are no signs of a reinfection.
