Vascular endoscopy for intravascular surgery--an experimental study.
A combination of endoscope and high-pressure saline irrigation system was tested in the occlusion of experimental aneurysms, and angioplasty and fibrinolysis of vascular occlusive lesions in canine femoral arteries. Endoscopy provided detailed information about the aneurysmal orifice and lumen and aided balloon placement and detachment. Endoscopy visualized the dynamic changes accompanying thrombolysis and the fine intimal injury due to angioplasty invisible on angiography. Vascular endoscopy is valuable for pre-, intra-, and postoperative evaluation of intravascular interventions.
