Baroreflex failure syndrome after bilateral excision of carotid body tumors: An underestimated problem Giorgio De Toma, MD, Virgilio Nicolanti, MD, Maurizio Plocco, MD, Giuseppe Cavallaro, MD, Claudio Letizia, MD, Gianfranco Piccirillo, MD, Antonino Cavallaro, MD Journal of Vascular Surgery Volume 31, Issue 4, Pages 806-810 (April 2000) DOI: 10.1067/mva.2000.103789 Copyright © 2000 Society for Vascular Surgery and International Society for Cardiovascular Surgery, North American Chapter Terms and Conditions

Fig. 1 Arteriograms with left (A ) and right (B ) carotid injections shows the CBTs and the splaying of the carotid arteries. The vascularity of the tumors at the carotid bifurcations should be noted.

Fig. 2 A, Recording of the systolic blood pressure (millimeters of Mercury) and heart rate expressed in R-R intervals (milliseconds) of the patient, 30 days after the bilateral surgery. B , The same recordings (milliseconds and millimeters of Mercury) in an age-matched healthy subject. The flatter pattern of the heart rate curve in the subject who underwent the operation should be noted.

Fig. 3 Spectral analysis obtained from the R-R intervals (milliseconds; A ) and systolic blood pressure (millimeters of Mercury; B ), simultaneously recorded beat-to-beat for 512 beats. The LF and HF components in the case presented (thin curve ) are much flatter than in a healthy subject (thick curve ).

Fig. 4 The α index pattern (milliseconds/millimeters of Mercury) calculated point by point at each frequency oscillation. In the case described, this invariably ranges around 5.0 ms/mm Hg (thin curve ), which is far lower than that of a normal subject (thick curve ).
