warfarin and Intestinal-Pseudo-Obstruction

Bromadiolone, commonly known as super warfarin, is a long-acting coumarin dicoumarin rodenticide. The mechanism of bromadiolone is mainly to inhibit vitamin K1 epoxide reductase and affect the synthesis of coagulation factors Ⅱ, Ⅶ, Ⅸ and Ⅹ, which causes blood coagulation dysfunction and systemic multiple organ hemorrhage. Here, we report of a case of bromadiolone poisoning patient who had digestive tract, abdominal hemorrhage, as well as secondary paralytic ileus. After blood product transfusion and vitamin K1 supplementation, the patient was discharged after the physical condition was improved. It's suggestied that clinicians should pay attention to rare complications to prevent missed diagnosis when treating other bromadiolone poisoning.. 溴敌隆是一种长效香豆素类抗凝类杀鼠剂，俗称"超级华法林"，其作用机制主要是抑制维生素K1环氧化物还原酶，影响凝血因子Ⅱ、Ⅶ、Ⅸ和Ⅹ的合成，致使机体凝血机能障碍，导致全身多脏器出血。本文报道一例溴敌隆中毒后导致消化道、腹腔出血，同时继发麻痹性肠梗阻的患者，给予输注血制品、补充维生素K1等治疗后，病情好转出院。提示临床医生在救治其他溴敌隆中毒时，要注意少见并发症，以免漏诊。.

A 69-year-old man was admitted to hospital with abdominal pain. In the four years prior to his presentation, he had undergone repeated transarterial chemoembolizations and injections for hepatocellular carcinoma. He underwent his 8th transcatheter arterial therapy one month prior to admission. Abdominal X-rays and contrast-enhanced computed tomography showed large amounts of small intestinal gas and venous thrombosis from the portal vein to the superior mesenteric vein, respectively. The thrombosis was reduced after anticoagulation therapy (heparin, antithrombin III, danaparoid sodium and warfarin). This is the first case report of paralytic ileus due to superior mesenteric venous thrombosis after transcatheter arterial therapy for hepatocellular carcinoma with an arterioportal shunt.
