Isolated nontraumatic @entity8 is rare. In this communication, 35 cases are presented; 24 cases (group 1) (22 male, 2 female) were diagnosed angiographically, and 11 (group 2) (10 male, 1 female) were observed at autopsy. In group 1, 23 of the @entity1 were @entity101 when they were first seen, and in 17 of them the @entity101 was of recent onset. Additional presenting signs and symptoms included @entity812 (10 @entity1 ), gross @entity811 (5), and @entity10 (6). Renal function was satisfactory. Renal vein @entity916 levels could be lateralized in 8 of 16 @entity1 . Isotope renograms performed in 18 @entity1 , showed @entity854 in 7, @entity66 in 6, and normal results in 5. Angiograms showed that the dissection was unilateral in 18 cases and bilateral in 6 cases. @entity4267 was observed radiographically in 22 cases and was bilateral in 12. In group 1, 13 @entity1 were treated with antihypertensive medication only, and 11 underwent operation. At follow-up (mean 52.0 months), the mean blood pressure were 128/88 mm Hg and 139/89 mm Hg for the medical and surgical groups, respectively. Eleven medical and nine surgical @entity1 continued to require antihypertensive drugs at follow-up. Among the 11 @entity1 in group 2, only 4 were @entity101 . In only one case the dissection may have contributed significantly to the @entity1 's @entity204 . These studies indicate that isolated nontraumatic @entity8 most commonly occurs in young @entity1 with coexistent @entity4267 . @entity101 is commonly present and therapy should be directed toward its control. In this study, blood pressure control was effectively accomplished with medical therapy.
