bubble_chart Overview Abdominal Angina Syndrome refers to a syndrome characterized by postprandial upper or mid-abdominal pain caused by relative intestinal ischemia. It is also known as visceral colicky pain, intestinal colicky pain, intermittent ischemic motility disorder, abdominal intermittent claudication, ischemic abdominal syndrome, chronic visceral ischemic syndrome, intermittent ischemia of the mesenteric artery, and abdominal vascular insufficiency syndrome.
bubble_chart Pathogenesis
Due to the hardening of the stirred pulse, the opening of the gastrointestinal branch of the abdominal stirred pulse becomes narrowed or blocked. The affected stirred pulse often occurs on the mesenteric membrane. After eating, the blood flow and demand of the intestines increase, causing relative ischemia and hypoxia of the intestines, leading to intestinal spasms and significant abdominal colicky pain.
bubble_chart Clinical Manifestations
1. It is more common in middle-aged and elderly male patients, with other manifestations of stirred pulse sclerosis.
2. Abdominal colicky pain often occurs 15-30 minutes after meals, lasting 1-3 hours, with the duration and intensity of pain related to the amount of food consumed. Abdominal colicky pain can be a precursor to intestinal vascular infarction.
3. Accompanied by nausea, vomiting, and diarrhea, patients often reduce food intake due to fear of pain, leading to weight loss.
4. Sometimes, a systolic vascular murmur can be heard in the upper abdomen.
5. Anemia, elevated white blood cell count, and positive fecal occult blood may occur.
bubble_chart Diagnosis
1. Clinical manifestations of colicky pain syndrome in the abdomen.
2. Abdominal X-ray examination shows no abnormal findings.
3. Abdominal stirred pulse angiography can determine the location and degree of vascular stenosis or obstruction.
4. Abdominal Doppler B-mode ultrasound examination is helpful for diagnosis.
bubble_chart Treatment Measures
The main procedure is the reconstruction surgery for abdominal cavity stirred pulse or mesenteric membrane stirred pulse. It can also involve the use of a stirred pulse catheter balloon to dilate or recanalize the narrowed or blocked segments. Drug therapy may include the use of vasodilators or anticoagulant therapy, such as taking anti-thrombotic pills or low-dose aspirin.
