Experimental use of an illuminated and magnetic tip, flow-directed pulmonary artery catheter for lung resection.
The authors performed a study to design and evaluate a device giving the surgeon added protection against pulmonary artery injury in a closed thoracic compartment. Eleven swine were used for a total of 12 lobectomies. A light-bearing, magnetic-tipped, modified Swan-Ganz catheter was passed through the jugular vein into the left pulmonary artery. By using magnetic guidance through a port site and balloon inflation, cessation of flow in the pulmonary artery was documented by Doppler. Twelve video-assisted lobectomies were performed. Nine of 12 (75%) lobectomies were completed successfully by using the magnetic-tipped, illuminated balloon catheter. In 4 cases, the catheter displaced because of the short left main pulmonary artery in swine. In one case, the balloon was recovered, and successful lobectomy was performed. The use of a magnetic-tipped, flow-directed device may provide an effective means of endovascular control during thoracoscopic pulmonary arterial dissection.
