Arterial blood pressure in cats can be measured by direct or indirect techniques. Most direct measurement techniques require sedation or anesthesia, which decreases blood pressure. The restraint and human intervention needed for indirect techniques cause blood pressure to increase. These limitations make the accurate assessment of blood pressure and the response to antihypertensive medications difficult to interpret. Radiotelemetry allows for direct measurement of the arterial blood pressure and heart rate without sedation, anesthesia, or animal handling during measurement. A surgical technique for the placement of radiotelemetry catheters and the complications associated with the technique have not been described in cats. Our purpose is to provide a detailed description of the placement of the modified implant model TA11PA-C40 (Data Sciences International), with accompanying illustrations, and to discuss complications associated with the procedure. Radiotelemetry catheters were surgically placed in the left femoral artery of 12 cats. The surgical procedure was completed within 50 min, and no surgical complications occurred in any cat. The radiotelemetry catheters were used for an average of 6.5 weeks (range, 5.5 to 9.5 weeks). This technique allows for long-term monitoring of ambulatory blood pressure and heart rate in the research setting. This methodology is especially useful for studies of the pathophysiology of hypertension and assessment of the efficacy of antihypertensive medications.
