Insights
Recurrent abdominal pain after coronary artery bypass grafting may signal celiac trunk stenosis. Prompt diagnosis and treatment, such as angioplasty, can resolve symptoms and improve patient outcomes.
Area of Science:
- Cardiology
- Vascular Surgery
- Gastroenterology
Background:
- Coronary artery bypass grafting (CABG) is a common procedure for coronary artery disease.
- Abdominal pain can be a complex symptom with multifactorial causes.
- Gastroepiploic artery grafts are utilized in CABG procedures.
Observation:
- A patient with a history of CABG experienced recurrent abdominal pain.
- Initial evaluations focused on gastrointestinal causes without resolution.
- A positive stress test prompted further cardiac and vascular investigation.
Findings:
- Coronary angiography revealed occluded native coronary arteries but a patent left internal mammary artery (LIMA) bypass.
- Aortography demonstrated severe (95%) stenosis of the celiac trunk.
- Successful angioplasty and stenting of the celiac trunk restored blood flow.
Implications:
- Celiac trunk stenosis should be considered in patients with abdominal pain post-CABG, especially those with gastroepiploic artery grafts.
- Vascular assessment of the celiac trunk is crucial in such cases.
- Intervention for celiac trunk stenosis can lead to complete symptom resolution and improved quality of life.
Abstract:
A man presented to the emergency room with recurrent episodes of abdominal pain. He had a history of coronary artery bypass grafting of the left internal mammary artery (LIMA) to the left anterior descending (LAD) artery and the right gastroepiploic artery to the posterior descending artery. After numerous gastrointestinal evaluations, a stress test was performed, which was positive. Coronary angiography showed a proximal occlusion of the LAD and right coronary artery and a normal functioning LIMA bypass. Aortography showed a 95% stenosis of the celiac trunk. Angioplasty and stent implantation of the celiac trunk was successfully performed. Six months later the patient was completely asymptomatic with a negative stress test. In conclusion, abdominal pain in patients who have undergone coronary artery bypass surgery using the right gastroepiploic artery should raise suspicion not only of a stenosis of the arterial conduit but also of a potential stenosis of the celiac trunk.

Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
