A Case of Femoral Arterial Bleeding by an Unknown Origin Metastatic Groin Lymph Nodes Carcinoma.

We report a case of femoral arterial bleeding complicated with hemorrhagic shock caused by bacterial infection attributed to an inguinal lymph node metastasis of carcinoma of unknown primary. Because of severe preoperative condition, a venous patch plasty of ruptured artery, and omentopexy for the groin was performed as a less invasive surgery. But the recurrence of bleeding was occurred postoperatively. A staged operation, hemostasis with a venous patch plasty at a first stage, and an extra-anatomical bypass soon after improvement of shock condition in a second stage, can be one of surgical procedures to save the lives and salvage limbs.
