Carotid body tumour excision: Anaesthetic challenges and review of literature

Surgical Excision of Carotid Body Tumor Through Modified Approach–A Case Report

“…Clinical diagnosis of CBT is usually confirmed with duplex ultrasound, CT, MRI and rarely conventional angiography [3,13]. As our patient reported with HPE report of the tumor and CT scan with contrast no further investigation was done considering the poor financial background and unaffordability.…”

“…If the clamping period is less than 10 min, the risk of developing neurological damage is very low as per Patetsis et al [17]. Temporary balloon occlusion of the carotid artery to assess the adequacy of collateral circulation across the circle of Willis can be done at the time of carotid angiography [3]. Hypothermia reduces the cerebral metabolic rate for oxygen (CMRO 2 ) by 6 % for every 1°C reduction in brain temperature [28°C.…”

“…Even though carotid body tumors are rare they are the first most common type of para ganglioma of head and neck region [2]. Frequently these tumors turn out to be malignant; hence operative intervention is the rule [2,3]. Scudder was the first surgeon to successfully remove this tumor preserving the carotid system [4].…”

Anaesthetic challenges in carotid body tumour resection: a case report and review of literature

“…Risk of considerable rapid blood loss during surgical resection 20 necessitates the use of invasive monitoring, hypotensive anaesthesia and availability of minimum four units of cross-matched blood.…”

“…21 Inj. Thiopentone (3-5 mg/kg/hr) infusion can be used to decreases the cerebral metabolic oxygen demand, 20 if carotid artery has to be clamped.…”
