Occlusion arteriography: diagnostic and therapeutic applicability of balloon catheters.
Occlusion arteriography using flow-directed Swan-Ganz balloon catheters is a safe and simple method, which opens up new technical, diagnostic, and therapeutic possibilities. Since 1976, occlusion arteriography with double-lumen Swan-Ganz balloon catheters and a percutaneous introducer system has been performed in 315 patients. The following advantages were found: (1) simplification of selective and subselective catheterization due to the flow-directed positioning of the balloon-tipped catheter; (2) high contrast of the arterial phase of the angiogram and demonstration of the smallest arteries as a result of a brief, complete occlusion of the main vessels ("standstill arteriogram"); (3) early and optimal demonstration of the corresponding venous system, especially optimization of the indirect splenoportogram and mesentericoportogram; (4) reduction of the volume of contrast agent usually needed for diagnostic reasons; (5) reliable and complete blockade of the tumor-feeding artery during transcatheter embolization with particulate substances; (6) reliable and complete blockade of the feeding artery as a preoperative protective measure in tumor nephrectomy and splenectomy.
