Reno-hepatic artery bypass for an inferior pancreaticoduodenal artery aneurysm with associated celiac occlusion

A minimally invasive approach for management of pancreaticoduodenal artery and gastroduodenal artery aneurysm with celiac artery occlusion

Management of pancreaticoduodenal artery aneurysms (PDAAs) and gastroduodenal artery aneurysms (GDAAs) with concomitant celiac occlusion represents a challenging clinical scenario. Here, we describe a 62-year-old female with PDAA and GDAA complicated by celiac artery occlusion due to median arcuate ligament syndrome. We used a staged, minimally invasive approach consisting of: (1) a robotic median arcuate ligament release; (2) endovascular celiac artery stenting; and (3) visceral aneurysm coiling. The findings from this case report represent a novel treatment strategy for the management of PDAA/GDAA with celiac artery compression secondary to median arcuate ligament syndrome.

A Hybrid Approach in the Management of a Large Pancreaticoduodenal Artery Aneurysm

Pancreaticoduodenal artery aneurysms (PDAA) are rare and represent a small fraction of known visceral aneurysms. We describe a case of a 79-year-old male with an 82 mm PDAA in the setting of chronic celiac artery occlusion. The patient was treated with an open repair. Due to the large size of the aneurysm and the dense adhesions to the surrounding tissues, vascular control of the superior mesenteric artery (SMA) was achieved by endovascular balloon occlusion and the aneurysm repaired with resection and primary aneurysmorrhaphy. The patient had an uneventful postoperative course.

Current management strategies for visceral artery aneurysms: an overview

Visceral artery aneurysms (VAAs) are rare and affect the celiac artery, superior mesenteric artery, and inferior mesenteric artery, and their branches. The natural history of VAAs is not well understood as they are often asymptomatic and found incidentally; however, they carry a risk of rupture that can result in death from hemorrhage in the peritoneal cavity, retroperitoneal space, or gastrointestinal tract. Recent advances in imaging technology and its availability allow us to diagnose all types of VAA. VAAs can be treated by open surgery, laparoscopic surgery, endovascular therapy, or a hybrid approach. However, there are still no specific indications for the treatment of VAAs, and the best strategy depends on the anatomical location of the aneurysm as well as the clinical presentation of the patient. This article reviews the literature on the etiology, clinical features, diagnosis, and anatomic characteristics of each type of VAA and discusses the current options for their treatment and management.

Management of pancreaticoduodenal artery aneurysm associated with coeliac artery stenosis

Pancreaticoduodenal and gastroduodenal artery aneurysms are rare but require early radiological or surgical intervention due to a high risk (61%) of rupture. A 71-year-old woman presented with an incidental 30-mm aneurysm arising from the inferior pancreaticoduodenal artery associated with coeliac axis stenosis. She underwent embolisation of the pancreaticoduodenal aneurysm, but the coeliac axis stenosis was not amenable to radiological intervention. She remained well at six months of follow-up and a repeat computed tomography angiogram six months later reported stable appearances. The management of pancreaticoduodenal aneurysms is discussed.

Polyarteritis nodosa-induced pancreaticoduodenal artery aneurysmal rupture

Polyarteritis nodosa (PAN) is a systemic, necrotizing vasculitis of small- and medium-sized arteries typically with multiorgan involvement. Most cases of PAN are idiopathic, although hepatitis B or C virus infections and hairy cell leukemia are important in the pathogenesis of some cases. PAN is characterized as segmental transmural inflammation of muscular arteries. Diagnosis is based on clinical suspicion, a negative immunofluorescence test for antineutrophil cytoplasmic antibodies, and whenever possible, biopsy conformation. Angiographic images may reveal microaneurysms affecting the renal, hepatic, or mesenteric vasculature. Aneurysmal formation and rupture are important complications that can be fatal. Treatment may warrant immunosuppression with steroids and cyclophosphamide. If left untreated, PAN can be fatal. To our knowledge, we report the second documented case of PAN-induced ruptured inferior pancreaticoduodenal artery aneurysm.

Inferior pancreaticoduodenal artery aneurysms associated with occlusive lesions of the celiac axis: diagnosis, treatment options, outcomes, and review of the literature

PURPOSE

To describe the presentation, treatment, and outcomes for 14 patients with aneurysms of the inferior pancreaticoduodenal arteries associated with occlusive lesions of the celiac axis, and to review the literature for similar cases.

METHODS

Over a period of 12 years, 14 patients (10 women and 4 men) ranging in age from 26 to 50 (mean 46) years were demonstrated to have aneurysms of the inferior pancreaticoduodenal artery origin associated with stenosis or occlusion of the celiac axis. All patients were treated by a combination of surgery and interventional radiology.

RESULTS

Outcome data collected between 3 months and 4 years (mean 2 years) demonstrated that all aneurysms remained excluded, and all 14 patients were well. The 49 case reports in the literature confirm the findings of this cohort.

CONCLUSION

In inferior pancreaticoduodenal artery aneurysm resulting from celiac occlusive disease, endovascular treatment is best achieved by stenting the celiac axis and/or embolizing the aneurysm when necessary.
