Late complication of a femoral monitoring catheter: a case of femoral false aneurysm treated surgically.

Femoral false aneurysms are rare. They are one of the main complications of femoral catheterization, trauma of this area, or the use of intravenous drugs. They usually occur in the days after femoral puncture, and only rarely occur years after the procedure or incident. Treatment often requires complex surgical methods. We report the management of a patient with a ruptured infected femoral false aneurysm that was diagnosed 4 years after a femoral puncture performed in intensive care unit to perform peripheral arterial catheter hemodynamic monitoring. The patient was operated with exclusion of the aneurysm and prosthetic bypass, associated with intravenous antibiotics adapted to the bacterial strain grown from the operative site, which resulted in a favorable outcome.
