Arterioenteric fistula is a rare but serious complication of enteric drained pancreas transplant, which may lead to massive gastrointestinal bleeding. We present 3 patients with failed enteric drained pancreas transplants and massive gastrointestinal bleeding secondary to arterioenteric fistula. One patient was treated by embolization and the 2 others by stent graft placement. Bleeding was successfully controlled in all cases, at follow up of 5 days, 8 months, and 12 months, respectively. One patient died 24 days after embolization, of unknown causes.

We conclude that interventional procedures can be successfully performed in the majority of patients with obstruction of splanchnic veins, with subsequent improvement of symptoms. Treatment should be customized according to the site and nature of obstruction.

Objective: This study aims to investigate long-term effects of iodinated radiographic contrast media used for coronary angiography (CAG) on the thyroid function in euthyroid patients. Methods: In a prospective observational cohort study, nonionic iodinated contrast material was electively used in 101 patients for coronary angiography. The patients were recruited without age restrictions and, at baseline, all had normal levels of free triiodothyronine (FT3), free thyroxine (FT4) and thyrotropin (TSH). The morphology of the thyroid was evaluated by thyroid ultrasonography (USG). Four and eight weeks after CAG, serum TSH, FT3 and FT4 levels were assessed. Results: Compared to a mean baseline level of 1.49 (25%-75%, range 13-2.21), follow-up TSH levels decreased significantly to 1.45 (25%-75%, range 1.98-0.92, p=0.017) and 1.40 (25%-75%, range 1.89-0.87, p=0.003) at 4 weeks and 8 weeks, respectively (p=0.008). No significant diffe-rence was observed in TSH levels between the 4 th and 8 th weeks (p=0.833). Conclusion: Iodinated radiographic contrast agents may cause subclinical hyperthyroidism in euthyroid patients undergoing CAG. (
