Unsuspected vascular disease: A potential limitation to the use of the intra‐aortic balloon

Since vascular tortuosity or stenosis may preclude placement of the Intra‐aortic balloon, 63 consecutive patients (37 men) having routine Judkins' cardiac catheterization had an aortogram prior to withdrawal of the last catheter. No patient had a history of claudication, palpable aneurysms, pulse deficit, or bruit. No complications occurred. Significant peripheral vascular disease was found in ten patients: three had aortic, one had iliac, and six had femoral stenosis or tortuosity. All were men. The age of patients with peripheral vascular disease was 61.4 ± 7.7 years, while those without were 56.9 ± 9.3 years (P = NS). No difficulty was encountered entering the femoral artery in any patient; there was difficulty advancing the catheter in five of ten (50%) patients with peripheral vascular disease and in three of 54 (6%) patients without (P < 0.002). Fifteen patients without peripheral vascular disease had normal coronary arteries, while none with peripheral vascular disease was normal. In patients with coronary disease, the number of vessels involved was the same in both groups. Peripheral vascular disease that might preclude placement of the Intra‐aortic balloon occurs in 14% of patients undergoing cardiac catheterization and 18% of patients with coronary artery disease. Aortography may be safely performed and should be considered during routine cardiac catheterization in patients who may require Intra‐aortic balloon placement.
