Renal and Mesenteric Arterial Disease

Renal/ Mesenteric Artery Stenosis

Sometimes the renal arteries (to the kidneys), or mesenteric arteries (arteries which supply the gut) may become narrowed or diseased. They may also become aneurysmal (larger than normal). Narrowing of the renal arteries can sometimes lead to refractory hypertension or renal failure. Dr Vivienne Moult is able to provide surgical management options for renal artery stenosis should it be require in consultation with your renal physician (kidney specialist). If there is a serious narrow or blockage of the mesenteric arteries (arteries to the gut), then this can cause acute or chronic mesenteric ischaemic - which can be a very serious and life threatening problem. Dr Vivienne Moult undertook a fellowship and gained valuable experience working with one of the best and well published mesenteric surgeons in the world. Dr Moult offers a full range of both endovascular and open surgical options to treat complex mesenteric vascular disease. 

Visceral Aneurysms

Sometimes aneurysms (a localised enlargement of the artery) can occur in the renal or mesenteric arteries. Aneurysms carry the potential risk of rupture which can be serious and life-threatening. Rupture risk of a visceral (within the abdomen) artery aneurysm is highest during pregnancy and childbirth, therefore any aneurysms of these vessels in females of child bearing age is usually recommended for repair. 

Visceral aneurysms in other patient groups may be recommended for repair if they reach certain threshold diameters. Small, sub-threshold aneurysms are often monitored and kept under close surveillance. Aneurysms of the splenic and renal arteries are the most common of the visceral aneurysms. Dr Vivienne Moult can assess your arteries and any aneurysms and provide individualised expert advice and treatment recommendations. 

Aneurysms may be treated using a number of different techniques such as coiling (blocks the aneurysm), stenting, or plugs (blocks the artery) or a combination of these. Open repair is sometimes required which may involve excision of the affected artery or bypass. No two aneurysms are the same and therefore your treatment must be individualised and carefully planned by a vascular surgeon such as Dr Vivienne Moult.
