[Bilateral femoro-popliteal acute recurrent arterial thrombosis in the course of heparin-induced thrombocytopenia (white thrombus syndrome)].

Heparin induced thrombocytopenia with thrombosis, or the "white clot syndrome" is a rare but very important complication of heparin therapy. The syndrome is idiosyncrasic, immune-mediated and not dose dependent and therefore is equally likely to occur with prophylactic and therapeutic heparin dosage regimens. We report a typical case of HIT that occurs with prophylactic heparin therapy and results in bilateral amputation of the lower limbs.

[Herniation of the cecum and ascending colon through Winslow's foramen and the lesser omentum. A case report].

Internal hernia into epiploic foramen is a rare clinical entity, representing 1% of all herniae and 8% of internal herniae. We report a peculiar case of internal herniation presented during a laparotomy for acute colecystitis where the caecum and ascending colon entered the lesser sac through the forame of Winslow and reentered the main abdominal cavity through a congenital defect of the lesser omentum.
