Emergency endovascular treatment of early spontaneous nonaneurysmal popliteal artery rupture in a patient with Salmonella bacteremia.

Rupture of a nonaneurysmal popliteal artery and subsequent pseudoaneurysm formation is an exceedingly rare event after bacteremia caused by Salmonella spp. Only a few cases have been reported in the literature. Moreover, spontaneous popliteal artery rupture resulting from this pathology, to our knowledge, has not been reported. We describe an early spontaneous rupture of the popliteal artery complicated by acute compartment syndrome in a 67-year-old man who had recently experienced fever, chills, and diarrheal syndrome and had sustained episodes of bacteremia infection, with isolation of S enteritidis. Immediate endovascular sealing of the bleeding site was achieved with a covered stent, and his recovery was uneventful. The long-term durability of endovascular repair in this type of pathology remains to be determined, however.
