A Case of Pseudo-xanthoma Elasticum Presenting with Ischaemic Claudication

AbstractA 37-year-old man presented with symptoms of intermittent claudication. Investigations revealed atypical calf vessel disease but no obvious aetiology. Ten years later he re-presented with worsening symptoms. CT angiography confirmed the atypical pattern of lower limb arterial disease but also noted calcification of the renal parenchyma, myocardium and scrotum. A diagnosis of pseudo-xanthoma elasticum was confirmed by skin biopsy. Pseudo-xanthoma elasticum is a rare condition that presents infrequently to vascular surgeons. Early recognition should prompt aggressive risk factor management to slow accelerated atherosclerosis. Clinicians should be aware of the clinical features of this condition to allow early diagnosis

Management of median arcuate ligament syndrome in patients who require pancreaticoduodenectomy

Pancreaticoduodenectomy is the standard treatment for localised neoplasms of the pancreatic head. The operation can be performed safely in specialist units but good outcome is compromised if postoperative blood flow to the liver and biliary tree is inadequate. Coeliac artery occlusion with blood supply to the liver arising from the superior mesenteric artery via the gastroduodenal artery is difficult to recognise, especially intraoperatively. Recognition of absent hepatic artery pulsation after occlusion of the gastroduodenal artery opens a dilemma: should the resection be abandoned or should vascular reconstruction be undertaken, adding risk to an already complex procedure? We describe two cases with a resectable pancreatic endocrine tumour in which coeliac artery occlusion caused by median arcuate ligament compression was identified from cross-sectional imaging and reconstructions. We highlight two different strategies to correct the vascular insufficiency and allow safe pancreatic resection
