Transabdominal ultrasound showed ( Video 1 )partially thrombosed aneurysm at the origin of the superior mesenteric artery with a light fusiform artery ectasia and parietal thrombotic deposition. It appeared hypoechogenic, eccentric with clear reduction of lumen calibre, and a color doppler signal characterized by clear aliasing due to increased flow velocities.

Abdominal angio TC ( Video 2 ) showed a large aneurysm, diameter mm 16,6x 27, of the proximal superior mesenteric artery, with mural thrombus and secondary high grade lumen stenosis.

 

Abdominal angiography was performed with femoral arterial approach and showed a high grade stenosis of the proximal tract (about 30 mm in length) of the mesenteric artery and an aneurysm with a diameter of 15x10 mm. ( Video 3 ).


Endoluminal treatment was then performed with axillar artery approach.The mesenteric stenosis and the aneurysm were first negotiated by means of a .014 guidewire; two stents were then placed to cover the aneurysm and to dilate the stenosis; the first, distal, was a Cordis Genesis stent (mm 7x24), the second ( mm 7x15), was added to the first and placed more proximal. The dilatation of the arterial stenosis was complete and the aneurysm disappeared. Six and twenty-two months follow-up showed a good dilatation of the arterial lumen (Video 4).

CLINICAL CASE

MESENTERIC SUPERIOR ARTERY THROMBOSIS IN TAKAYASU’S ARTERITIS

A 55-year-old woman presented with an history of abdominal postprandial pain, initially sporadic (after rich meal), then more and more frequent, and finally coliky-like.


DISCUSSION

Twenty-four months after the procedure the patient is still in good health: no more abdominal postprandial pain. After complete diagnostic workup a diagnosis of Takayasu’s Arteritis was made; meantime the patient follows a glucocorticoid therapy.

Takayasu’s disease (“pulseless disease”) is an idiopathic chronic inflammatory disorder that most often affects aorta and its branches; the splanchnic vessels unusually are involved. It is most prevalent in adolescent girls and young women and, although more common in the Orient, it is neither racially nor geographically restricted. An association of the disease has been described with HLA-DR2, MB1 in Japan and HLA-DR4, MB3 in the United States and with Crohn’s disease and ulcerative colitis. The disease is a panarteritis with inflammatory mononuclear cell infiltrates and occasionally giant cells.

There is marked intimal proliferation and fibrosis, scarring and vascularization of the media and disruption and degeneration of the elastic lamina leading to narrowing of lumen with or without thrombosis, aneurysm and rarely rupture of involved vessels. The vasa vasorum are frequently involved. Treatment is large doses of glucocorticoids prior to reconstructive surgery, and the 5-year survival rate is higher than 90%.
