Sleep-Mediated Heart Rate Variability after Bilateral Carotid Body Tumor Resection

Bilateral carotid-body resection.

FIGuRE 1. Lateral tomogram of neck showing forward displacement of trachea by soft tissue mass (hollow arrows) with luminal narrowing (single solid arrow). extrinsic obstruction of the trachea is an extremely rare phenomenon. Elderr mentioned a rare patient with medias-tinal lymphoma may require immediate tracheostomy. Our patient did not present with peripheral bulky disease and her chronic ly...

Obstructive sleep apnea following bilateral carotid body resection.

A patient who had undergone bilateral carotid body resection five years earlier for palliation of chronic airflow obstruction was found to have severe obstructive sleep apnea. He presented with hypercapnic respiratory failure, which improved after tracheostomy. A physiologic mechanism is proposed to explain this association. Previously reported studies of anesthetized animals suggest that loss ...

Bilateral carotid body tumor resection in a female patient☆

Introduction Carotid body tumors also called carotid paragangliomas are rare neuroendocrine neoplasms derived from neural crest cells, approximately 3% of all paragangliomas occur in the head and neck area (Xiao and She, 2015); although they represent 65% of the head and neck paragangliomas (Georgiadis et al., 2008). Presentation of case We present the therapeutic management of a 65-year-old ...

Heart Rate Variability in Sleep Studies

NORMALIZED SPECTRAL BAND POWERS/VARIANCES ARE DERIVED MEASURES REFLECTING AUTONOMIC ACTIVITY, COMMONLY COMPUTED IN MANY HEART rate variability (HRV) data analysis software packages available to sleep researchers, particularly for the low-frequency (LF: often 0.04-0.15 Hz) and high-frequency (HF: often 0.15-0.40 Hz) spectral power/variance bands. The normalized (or normalized unit) spectral indi...
