Hazards of straight catheter aortography in the tortuous abdominal aorta. 1979

A J Gerlock, and V Goncharenko

Twenty abdominal aortograms utilizing a straight-tipped catheter were evaluated for catheter tip motion during the injection of contrast media. The catheter tips were stable in 15 patients but showed downward recoil in the remaining 5 patients. These 5 patients had marked tortuosity of their abdominal aortae which was felt to be the etiology of the catheter tip instability. Based on this finding, the use of a straight-tipped catheter is to be discouraged in patients with extreme tortuosity of the abdominal aorta.

D002404 Catheterization Use or insertion of a tubular device into a duct, blood vessel, hollow organ, or body cavity for injecting or withdrawing fluids for diagnostic or therapeutic purposes.
