SUMMARY
Eight cases of aorto‐arteritis with narrowing of the abdominal aorta showed a marginal artery of Drummond on aortography. There was no case with clinical evidence of abdominal angina. In six cases there was occlusion or narrowing of the superior mesenteric artery with flow of blood in the marginal artery from the inferior to the superior mesenteric artery and these patients also had hypertension resulting from involvement of renal artery/arteries. The other two patients with involvement of the inferior mesenteric artery, showed the marginal artery being filled from the superior mesenteric artery and were normotensive since there was no renal artery involvement. There were only four patients in whom the aortic arch or its branches were also involved. Two patients had evidence of active pulmonary tuberculosis.
