Insights
A 57-year-old woman with polyarteritis nodosa had visceral artery aneurysms successfully treated. A hybrid operation involving bypass and embolization resolved complex lesions, avoiding hepatic ischemia.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Rheumatology
Background:
- Polyarteritis nodosa (PAN) can affect visceral arteries, leading to aneurysms and stenosis.
- Incidental detection of visceral artery aneurysms necessitates careful treatment planning.
Observation:
- A 57-year-old woman presented with incidentally detected celiac axis occlusion, superior mesenteric artery stenosis, and multiple visceral artery aneurysms.
- Endovascular embolization was deemed high-risk due to potential hepatic ischemia.
Findings:
- A hybrid surgical approach was successfully employed.
- The procedure included antegrade aorto-celiac-superior mesenteric artery bypass, coil embolization, and aneurysm resection.
- This resolved complex PAN-related visceral artery lesions.
Implications:
- Hybrid operations offer a viable solution for complex visceral artery aneurysms when endovascular methods are contraindicated.
- Successful treatment preserved organ perfusion and avoided major complications like hepatic ischemia.
- This case highlights the importance of multidisciplinary collaboration in managing rare vascular manifestations of systemic diseases.
Abstract:
A 57-year-old woman presented to vascular surgery clinic with visceral artery aneurysms that were incidentally detected during regular check-up. Imaging studies revealed occlusion of the celiac axis and severe stenosis of the superior mesenteric artery and 3 aneurysms along the posterior and inferior pancreaticoduodenal arteries, as well as the right gastroepiploic artery. Endovascular embolization of all aneurysms was rejected because of the risk of hepatic ischemia. These complicated lesion caused by polyarteritis nodosa were successfully treated using a hybrid operation with coil embolization, aneurysm resection, and antegrade aorto-celiac-superior mesentery artery bypass.
