Protein C and antithrombin III represent main inhibitors of the plasmatic coagulation system. Due to the lack of practicable assays the clinical importance of protein C was only established during the last six years. In familial protein C deficiency 77% of patients present with recurrent venous thromboses, half of them below the age of 30. In addition to recurrent superficial thrombophlebitis more serious manifestations like deep vein thrombosis and pulmonary embolism have been described. Mesenteric vein thrombosis has been reported in only 5 cases all of which could be controlled by conservative treatment. In our patient protein C deficiency was discovered 10 years after the angiographic diagnosis of portal and mesenteric vein thrombosis. Thereafter, the patient complained of recurrent abdominal discomfort. Intestinal ischaemia due to mesenteric vein thrombosis required segmental resection twice. Postoperatively the patient was heparinized. After excluding a secondary protein C deficiency due to a lack in vitamin K, hepatic disease, or disseminated intravascular coagulation, long-term anticoagulation by dicumarol was implemented as therapy of first choice.

This study evaluated the indications, surgical techniques, and outcomes of allograft pancreatectomy based on a single center experience. Between 2003 and 2013, 47 patients developed pancreas allograft failure, excluding mortality with a functioning pancreas allograft. Early graft loss (within 14 days) occurred in 16, and late graft loss in 31. All patients with early graft loss eventually required allograft pancreatectomy. Nineteen of 31 patients (61%) with late graft loss underwent allograft pancreatectomy. The main indication for early allograft pancreatectomy included vascular thrombosis with or without severe pancreatitis, whereas one recipient required urgent allograft pancreatectomy for gastrointestinal hemorrhage secondary to an arterioenteric fistula. In cases of late allograft pancreatectomy, graft failure with clinical symptoms such as abdominal discomfort, pain, and nausea were the main indications (13/19 [68%]), simultaneous retransplantation without clinical symptoms in 3 (16%), and vascular catastrophes including pseudoaneurysm and enteric arterial fistula in 3 (16%). Postoperative morbidity included one case each of pulmonary embolism leading to mortality, formation of pseudoaneurysm requiring placement of covered stent, and postoperative bleeding requiring relaparotomy eventually leading to femoro-femoral bypass surgery 2 years after allograftectomy. Allograft pancreatectomy can be performed safely, does not preclude subsequent retransplantation, and may be lifesaving in certain instances.

Barium enema investigation is regarded as a safe investigative procedure. Rarely, it may cause complications such as colonic perforation and barium intravasation. Barium intravasation may be caused by the inadvertent introduction of the catheter into the vagina, thereby into the vaginal venous plexus. It may also occur through mechanical colonic perforation with the catheter, or via diseased bowel conditions. This may lead to complications such as liver microabscesses, massive pulmonary embolism, hypovolemic shock, disseminated intravascular coagulopathy and even sudden death. With that in mind, we would like to report an interesting case of barium intravasation into the portal venous system via the vagina venous plexus. The patient experienced abdominal discomfort with mild per vaginal bleed and went into disseminated intravascular coagulopathy. She received supportive management and she made a full recovery.
