Bezoar as a cause of portal vein pneumatosis: a case report

Pneumatosis of the portal vein is considered a rare imaging sign rather than a disease. It usually occurs in patients with digestive tract diseases such as intestinal obstructive diseases, mesenteric vascular diseases, closed abdominal trauma, and liver transplantation. Because of its high mortality rate, it is also termed the “sign of death.” Hawthorn contains tannic acid, and seafood is rich in calcium, iron, carbon, iodine, and other minerals and proteins. Thus, consuming both hawthorn and seafood together can result in the formation of an indigestible complex in the body, acting as the main pathogenic factor in patients with intestinal obstruction. We herein describe a patient with duodenal obstruction caused by hawthorn who developed the hepatic portal venous gas sign and was cured by nonsurgical treatment.

Portal gas is relatively rare, and the majority of reported cases have shown it to have a close relation to bowel diseases. At present, portal exploration usually begins with color Doppler sonography, and clinicians now possess a good understanding of color Doppler findings of a wide spectrum of portal abnormalities. However, the color Doppler sign we present in this article has not been reported before. We report two cases of ischemic bowel disease in which B-mode ultrasound showed multiple hyperechoic spots moving in the portal vein; the color Doppler appearance was as if the portal vein was on fire (flaming portal vein sign). Knowledge of this simple color Doppler sign helps to improve the diagnostic strategies in patients with portal gas.

Extensive Aeroportia, Operate or Not to Operate? A Report of a Challenging Case

Aeroportia is the presence of gas in the portal vein. It is considered an ominous radiological sign with poor outcomes. Historically, it was associated with bowel necrosis, and surgery was mandated in all cases. Herein, we present a challenging case of portal venous gas and its management. An 87-year-old male patient, with multiple co-morbidities, presented with abdominal pain. The computerized tomography (CT) scan showed extensive portal venous gas without evidence of bowel ischemia. Initially, he was managed conservatively, but his clinical condition deteriorated. So, an exploratory laparotomy was performed which revealed multiple superficial splenic abscesses covering the surface of the spleen and a pale segment of jejunum with questionable viability. Splenectomy was performed and second-look laparotomy was planned to assess the small bowel viability. Second-look laparotomy revealed dusky discoloration of 30 cm jejunal segment. The affected segment was resected. The patient improved after surgery and was discharged home. In conclusion, aeroportia (portal venous gas) is a radiological entity. The clinical condition of the patient must be kept in consideration to manage the patients optimally. However, if the patient deteriorates, a high index of suspicion for mesenteric ischemia and early surgical intervention are the keys to save the patients' life.
