Tumores do corpo carotídeo: revisão de oito casos e abordagem cirúrgica

Abstract

Carotid body tumors are rather uncommon. Even though there is a great amount of literature on the subject, the controversy regarding its biological behavior and therapeutics and mainly, the surgical management still remains. We present eight patients with carotid body tumors (total of 9 tumors, one bilateral) surgically treated at the Neurosurgery Department of Santa Casa in Belo Horizonte, from 1989 to 1999. The age ranged from 11 to 66-years-old (35,6+/-17.7). Four patients were women and four were men. We had satisfactory postoperative results with low morbidity and no deaths. Based on our experience and on the review of the literature, some aspects of this disease are discussed. We conclude that carotid body tumors are uncommon and should be treat with carefully surgery techniques to obtain low morbi-mortality rates.

“…Although well-delineated, they are nonencapsulated tumors that are highly vascularized by branches of the external carotid artery and its vasa vasorum. 3,4,[9][10][11] Generally, the initial manifestation reported by patients is presence of a painless mass palpable in the lateral neck. Imaging exams such as computed tomography and color Doppler ultrasonography of the cervical region will show the tumor and its limits, providing information for staging and helping with choice of treatment.…”

“…1,2 This type of tumor accounts for 60-70% of paragangliomas of the head and neck, they are highly vascularized and, although well-delineated, they are not encapusulated and proximity with important structures, such as nerves, combined with dense vascularization make resection difficult. [2][3][4] Diagnostic suspicion is aroused by clinical assessment, with autonomic symptoms, and/or imaging exams such as angiotomography (gold standard), with presence of the lyre sign and intense vascularization at the lesion site, while Doppler ultrasonography shows a vascularized mass in the region of the carotid bifurcation. Additionally, angiotomography and magnetic resonance angiography can identify location, extent, correlations with adjacent structures, and the vascular nature of the tumor.…”

A importância da embolização pré-operatória no tratamento do tumor do corpo carotídeo: relato de caso e revisão da literatura

“…Schudder was the first to remove one of these tumors and preserve the external and internal carotid arteries. 2 Carotid glomus tumors are the most frequent among paragangliomas; according to Prache et al, its incidence is 1:1,170,000. They are benign tumors, which are developed in the vessel adventitia, in the common carotid artery bifurcation, in posteromedial location.…”

“…The lesion is bilateral in about 5% of cases, and may reach 32% if it has family origin (dominant autosomal). 2 Attention should be given to differential diagnoses of masses in the neck region. Singh et al described a case of pulsatile mass in the neck in which clinical examination and tomography suggested diagnosis of carotid body tumor.…”

“…1 The most common differential diagnosis is with increased lymphatic nodules, brachial cyst, mixed tumors, and carotid artery aneurysm. 2 Such range of differential diagnoses makes this a rich clinical case.…”
