Median arcuate ligament syndrome: vascular surgical therapy and follow-up of 18 patients.
ABSTRACT The median arcuate ligament syndrome (MALS) or celiac artery compression syndrome is a rare vascular disorder caused by an extrinsic compression of the celiac artery from the median arcuate ligament, prominent fibrous bands, and ganglionic periaortic tissue. Clinical symptoms are postprandial abdominal pain, nausea, vomiting, unintentional weight loss, and sometimes, abdominal pain during body exercise caused by an intermittent visceral ischemia. The aim of this study was to evaluate the operative management of patients with MALS in our institution, especially in consideration of various vascular reconstructive techniques.
Between June 2000 and January 2009, a total of 341 patients were treated in our department for vascular pathologies of the visceral arteries (225 chronic visceral ischaemia, 84 acute visceral ischaemia, and 14 visceral artery aneurysms). In a retrospective study of 18 patients with MALS, the records, clinical symptoms, diagnostic evaluation, and surgical procedures were compiled. This was completed by a reassessment for a follow-up.
A MALS was diagnosed in 15 female (83.3%) and three male (16.7%) patients. The mean patient age was 46.2 years (range 20-68 years). The diagnosis of MALS was based on a radiological analysis in all patients by a digitally subtracted angiogram, but duplex ultrasound was used lately more frequently to study the influence of respiration on the stenotic degree of the celiac trunk. All 18 patients were treated with open surgery in an elective situation. Due to the local and specific pathology of the celiac trunk with a fixed stricture or stenosis, out of 18 cases beside decompression, 11 (primary, seven; secondary, four patients) further procedures were performed on the celiac artery (aorto-celiac vein interposition n = 6, aorto-hepatic vein interposition n = 1, resection of the celiac artery and end-to-end anastomosis n = 2, patchplasty of the celiac artery with vein n = 1, and transaortic removal of a stent of the celiac artery n = 1) Follow-up was obtained in 15 patients (83.33%) with a mean duration after surgery of about three and a half years (40.68 months, range from 2 to 102 months). Eleven of the 15 patients (73.33%) were completely free of abdominal symptoms, and nine of them had gained between 3 and 10 kg in weight after surgery. The weight of two patients remained stable. Of the 11 patients with a successful outcome in the follow-up, six of them had undergone decompression solely. In the other five patients, vascular co-procedures on the celiac trunk had been performed.
The MALS is a rare vascular disorder caused by an extrinsic compression of the celiac artery and induces upper abdominal, mostly, postprandial pain. A definite diagnosis of MALS can be achieved by lateral aortography of the visceral aorta and its branches during inspiration and expiration. Open surgical therapy is a safe and reliable procedure with no mortality and low morbidity. As to the local and specific pathology of the celiac trunk after decompression with fixed stricture or stenosis, further vascular procedures are necessary. The long-time follow-up seemed adequate. The laparoscopic approach reduces the procedure of decompression only, something which seemed inadequate for most cases. Endovascular treatment with percutaneous transluminal angioplasty and insertion of a stent does not solve the underlying problem of extrinsic compression of the celiac trunk and often requires open procedures during the long-term course. Due to the low incidence of MALS, no guidelines will do justice to all the patients sufficiently, and the choice of treatment must depend on the specific clinical situation for each patient.

ABSTRACT: Duodenal metastasis from renal cell carcinoma is rare, and even rarer is a massive gastrointestinal bleeding from such tumours. Coeliac occlusive disease, although rarely symptomatic, can lead to ischaemic changes with anastomotic dehiscence and leaks when a patient undergoes pancreatoduodenectomy. A 41-year-old man with known metastasis to the adrenal glands and the second part of the duodenum close to the ampulla of Vater from clear cell renal cell carcinoma was admitted to our department due to massive gastrointestinal bleeding from the duodenal metastasis. Endoscopic control of the bleed was not possible, while the bleeding vessel embolization was able to control the haemorrhage only temporarily. An angiography during the embolization demonstrated the presence of stenosis of the coeliac artery and also hypertrophic inferior pancreaticoduodenal arteries supplying the proper hepatic artery via the gastroduodenal artery (GDA). The patient underwent emergency pancreatoduodenectomy with preservation of the gastroduodenal artery. The patient had an uneventful recovery and did not experience further bleeding. Also the blood flow to the liver was compromised as shown by the normal liver function tests (LFTs) postoperatively. To the best of our knowledge, this is the first report of a preservation of the GDA during an emergency pancreatoduodenectomy.Case reports in surgery. 01/2014; 2014:218953.

ABSTRACT: Median arcuate ligament syndrome is an anatomic and clinical entity characterized by dynamic compression of the proximal celiac artery by the median arcuate ligament, which leads to postprandial epigastric pain, vomiting, and weight loss. These symptoms are usually nonspecific and are easily misdiagnosed as functional dyspepsia, peptic ulcer disease, or gastropathy. In this report, we presented a 72-year-old male patient with celiac artery compression syndrome causing recurrent abdominal pain associated with gastric ulcer and iron deficiency anemia. This association is relatively uncommon and therefore not well determined. In addition, we reported the CT angiography findings and three-dimensional reconstructions of this rare case.Korean journal of radiology: official journal of the Korean Radiological Society 07/2014; 15(4):439-42. · 1.32 Impact Factor

ABSTRACT: Magnetic resonance (MR) angiographic techniques optimize the visualization of the vasculature at MR imaging. MR angiography has several advantages over Doppler ultrsonography and computed tomographic angiography, with adaptable protocols to answer specific clinical questions. Novel noncontrast MR angiographic techniques now enable assessment of the abdominopelvic vasculature without administration of gadolinium-based contrast media. This article reviews MR angiographic techniques and discusses applications for arterial and venous evaluation in the abdomen and pelvis.Radiologic Clinics of North America 07/2014; 52(4):839-859. · 1.83 Impact Factor
