We present a case report of early surgical treatment of abdominal compartment syndrome after aortobifemoral bypass. A 73-year-old man was admitted to the I.I. Mechnikov North-Western State Medical University with critical lower limb ischemia. Aortobifemoral bypass with a synthetic prosthesis was performed via laparotomy. The postoperative period was complicated by the dynamic bowel obstruction. The patient's condition worsened (hypovolemic and septic shock, respiratory failure due to severe pneumonia). Initial tactics was conservative. Signs of bowel ischemia (pneumatosis of the intestinal wall, gas in the portal vein) were identified using “point of care” ultrasound, which led to a change in the treatment tactics. On the same day, decompression relaparotomy was performed and the intestinal decompression tube was inserted. The postoperative period proceeded with positive dynamics: early extubation with acceptable parameters of gas exchange, minimal dosages of vasopressor support. Bowel function improved and stool appeared on the 2nd day after surgery. Gas in the portal vein is an ultrasound phenomenon, which in 70 % of cases suggests necrosis of the intestinal wall. The detection of such a symptom in patients after the abdominal aorta surgery may indicate bowel ischemia, since mesenteric circulation disorders primarily develop in the inferior mesenteric artery. This condition requires urgent surgical intervention, but its differential diagnosis with postoperative paralytic ileus is not always possible, especially in the early stages. We demonstrate a case of early gas detection in the portal vein and the emergency intervention that allowed preventing irreversible ischemic damage of the bowel. “Point of care” ultrasound can help suspect this condition and determine the indications for early surgical intervention, which can positively influence the outcome.
