Three patients with saccular aneurysms arising from unilaterl renal arteries or their distal tribut-aries were presented together with a review of reports from the Japanese Literatures. One hundred and eleven patients (51 males, 59 females and 1 unspecified), 1 to 71 year in age, displayed 127 renal artery aneurysms. Seventy-four patients had hypertension. The blood pressures of the males and females were 177±6/107±5 and 171±6/105±5 mmHg (mean±S.E.), respectively. Solitary aneurysms affected 50 patients and multiple ones occurred in 15 subjects. The blood pressures of the former and the latter group were 171±5/103±4 and 185±8/113±5mmHg (mean±S.E.), respectively. These differences were not statistically significant. The blood pressures of the patients with jet-type aneurysms were considerably higher than those of the subjects with saccular type aneuryms (197±5/113±3s/161±6/99±5, mmHg, mean±S.E., respectively). Of the 53 patients with hypertension, high blood pressure was improved in 42 patients following the treatment. Subsequently, the necessity for curative measures, either surgical or nonsurgical, can be emphasized in patients with renal aneurysms.
