BACKGROUND Pulmonary thromboembolism (PTE) sometimes leads to a shock state and sudden death due to acute massive pulmonary arterial thrombosis. The origins of pulmonary arterial thrombi are varied, but most arise from deep vein thrombosis. We herein presented a very rare cause of PTE due to paradoxical embolism caused by arteriovenous fistula from common iliac artery to common iliac vein. ⋯ This suggested that the emboli had passed through the arteriovenous fistula from the right common iliac artery to the common iliac vein. CONCLUSIONS This is a very rare cause of fatal paradoxical pulmonary thromboembolism. Paradoxical emboli passing through arteriovenous fistula from the right common iliac artery to the common iliac vein are a rare cause of PTE.

BACKGROUND Acute hypotensive transfusion reaction (AHTR) is characterized by the abrupt onset of hypotension immediately after the start of transfusion and usually resolves when transfusion ceases. Recent studies have shown an association with pre-operative treatment with an angiotensin-converting enzyme (ACE) inhibitor. This report presents two cases of AHTR in non-related patients and describes the diagnosis and management. ⋯ CONCLUSIONS AHTR is a diagnosis of exclusion, based on laboratory and clinical findings. Antibody-mediated acute hemolytic transfusion reaction and any other causes of hypotension should be excluded as rapidly as possible. Patients who are at high risk of intraoperative bleeding might benefit from cessation of ACE inhibitors pre-operatively.

BACKGROUND Endoscopic retrograde cholangiopancreatography for common bile duct stone in patients who underwent gastrectomy and Roux-en-Y anastomosis is challenging. We report a case in which we performed endoscopic retrograde cholangiopancreatography through a small-intestinal incision approach for a common bile duct stone, which had developed after total gastrectomy and Roux-en-Y anastomosis. CASE REPORT An 86-year-old woman with a history of laparoscopic-assisted total gastrectomy and R-Y anastomosis and incision of the common bile duct and cholecystectomy for common bile duct stone by open surgery 3 years ago presented with abdominal pain. ⋯ An incision on the Y limb of the Roux-en-Y anastomosis 20 cm from the jejunojejunal anastomosis and insertion of an endoscope through this opening were performed to extract the common bile duct stone. The patient was discharged on postoperative day 22 without complications. CONCLUSIONS For a patient with a common bile duct stone, who underwent gastrectomy and Roux-en-Y anastomosis, with firm adhesions at the porta hepatis, combined endoscopy and open surgery using a small-intestinal incision approach can be effective when small-bowel endoscopes are unavailable or the cannulation to Vater's papilla by them is difficult.

Retropharyngeal Hematoma as an Unusual Presentation of Myelodysplastic Syndrome: A Case Report.
BACKGROUND Retropharyngeal hematoma is a relatively rare diagnosis that requires a high clinical suspicion and stabilization of the airway to prevent rapid deterioration. We report a case of a spontaneous retropharyngeal hematoma in an elderly patient with myelodysplastic syndrome and associated thrombocytopenia. CASE REPORT A 90-year-old man with myelodysplastic syndrome was brought to the Emergency Department with complaints of difficulty swallowing and muffled voice for 24 hours. ⋯ CONCLUSIONS This case adds to the growing body of literature on spontaneous retropharyngeal hematomas. High clinical suspicion is warranted in patients who present with acute dysphagia, odynophagia, and dysphonia. Prompt imaging and airway management are vital in managing patients with this condition.

A Case of Heyde Syndrome with Resolution of Gastrointestinal Bleeding Two Weeks After Aortic Valve Replacement.
BACKGROUND Heyde syndrome is the association between gastrointestinal (GI) bleeding from arteriovenous malformation (AVM) and aortic stenosis. The aim of this study was to review Heyde syndrome and to discuss the management of this condition. CASE REPORT A 56-year-old female with a history of severe aortic stenosis and recurrent GI bleeding secondary to small bowel AVM, presented for hospital admission with melena and maroon blood in her stool. ⋯ At the 6-month follow-up she showed stable hemoglobin at 14.3 gm/dL without further episodes of GI bleeding. CONCLUSIONS Physicians need to consider Heyde syndrome in patients with aortic stenosis and GI bleeding secondary to angiodysplasia. Physicians should also be attentive in patients with Heyde syndrome presenting with GI bleeding after undergoing aortic valve replacement, as GI bleeding might take time to resolve completely in these patients.
