A carotid artery resection and replacement including neck dissection are used as a method of treatment for head and neck cancer with infiltration into the carotid artery. The recent development of imaging technique makes it easy to estimate the detailed anatomical relationship between the tumor infiltration into the carotid artery, it's resection and replacement are indicated at radical neck dissection. To detect any possibility of cerebral ischemia at the time of ligation of carotid artery, a temporary occlusion test of internal carotid artery with a ballon catheter (balloon occlusion test) is performed. Recently, we performed a carotid artery resection and replacement using an artificial vessel Gore-Tex) in a case of neck cancer with infiltration into the carotid artery.

Objectives: We studied what is the role of elective carotid artery resection in the management of advanced cervical metastatic cancer. Materials and Methods: 5 patients with elective carotid artery resection in advanced metastatic cervical cancer were reviewed retrospectively. The patients underwent complete neuroradiologic evaluation, including CT/MRI. angiography, duplex doppler, balloon occlusion test with EEG, and brain SPECT for determination of compatible collateral circulation after carotid artery resection. Results: Perioperative complication were appeared in 2 patients those were middle cerebral arterial infarction and mediastinal bleeding. Postoperative mortality rate was 20%. 4 patients recurred within 1 year. Conclusion: Preoperative collateral study rarely provide whether resection carotid artery or not. Elective carotid artery resection cannot provide locoregional control of tumor and don't promote survival.

To predict preoperatively the safety of permanent occlusion of an internal carotid artery with $^{99m}Tc$-HMPAO brain single photon emission computed tomography(SPECT) from an objective point of view, Twenty-four patients underwent balloon test occlusion (BTO) of the internal carotid arteries because of neck and skull base tumors. The authors assessed the uptake of both middle cerebral artery territories before and during BTO with $^{99m}Tc$-HMPAO brain SPECT using semiquantitative analysis method and compared the results with other factors(neurologic examination, arterial stump pressure and electroenceph-alogram). Nineteen patients had not experienced neurological deteriorating or any problem during BTO. Their comparative uptakes of the middle cerebral artery territories were 95 to 101% of the pre-BTO state. The remaining five patients showed severe neurologic symptoms such as transient hemiplegia and unconsciousness. Their comparative uptake of the middle cerebral artery territories were 77 to 85% of the pre-BTO state, and were well matched with other factors. $^{99m}Tc$-HMPAO brain SPECT before and during BTO seems to be a simple and objective method for prediction of permanent neurologic deficits when the comparative uptake of middle cerebral artery territories during BTO is lower than 85% of that before BTO.
