We report a case of a 6-year-old female with acute gastric volvulus with total gastric necrosis and ischemia of the surrounding organs. Congestion necrosis occurs because of strangulation. It is considered that this case was caused by elevated intragastric pressure with marked stomach dilation. Thus, rapid decompression was essential.

Patients with hepatic arteriovenous malformations rarely present with pulmonary hypertension. We report the case of a 3-month-old boy who developed severe pulmonary hypertension due to a hepatic arteriovenous malformation. The use of pulmonary vasodilators to treat the patient's pulmonary hypertension worsened his high-output heart failure. This is the first case in which emergency hepatectomy rescued a patient with hepatic arteriovenous malformations who developed pulmonary hypertension.
