[Pericardial patch in the treatment of peripheral arterial prosthesis infections]

Prosthetic vascular infections are rare, occurring in less than 3 % of cases. If left untreated within the required timeframe, serious complications such septic shock and anastomotic rupture with hemorrhage may occur and lead to the patient's death. Targeted and prolonged intravenous or oral antibiotic therapy is necessary but insufficient without surgical revision and removal of the infected prosthetic material. Once the infected prosthetic material is removed, blood continuity must be restored to ensure downstream vascularization and avoid amputation. There are two types of repair: extra-anatomical and in situ reconstructions. For the latter, it is ideal to avoid using prosthetic material. The solutions described in the literature are most often autologous venous grafts and cryopreserved arterial allografts. These are not always available. An alternative is to use a bovine pericardial patch, shaping it into a tube on the table with a longitudinal suture. We report a case of an infected common femoral artery prosthesis replaced with a pericardial patch and covered with the sartorius muscle.
