Resection of @entity10470 can be difficult to perform because of its site, vascularity, arterial adherence and local cranial nerve involvement. Advances in vascular surgical technique have reduced the risks of perioperative complications such as @entity130 , @entity64 and @entity204 . From January 1980 to May 1994 20 @entity1 (22 @entity10470 ) were examined. All @entity1 except one were evaluated with a preoperative angiography. No preoperative embolization was performed. Thirteen @entity1 underwent ultrasonography, nine a CT scan of the neck, 5 magnetic resonance scanning and two magnetic resonance angiography. One old @entity1 refused operation. The authors report their experience on 21 carotid body @entity5 resections (14 Shamblin group I and 7 group II @entity1823 ). Surgical technique is based on subadventitial resection (18 excisions) and 3 resections were performed from the medial surface of the carotid bifurcation which had been partially absorbed into the mass. In the last 15 operations intraoperative Somatosensorial Evoked Potential (SEP) monitoring has been used. Only two @entity1 required arterial repair because intimal dissection and another @entity1 needed vagus nerve section. The ligation of external carotid artery and internal carotid resection with graft replacement were never necessary in these @entity1 . No early or late @entity204 occurred and no recurrences were detected at follow-up.
