Three hundred forty-one needle aspiration biopsies (NAB) of major salivary gland tumors were performed over a 32-year period. Eighty percent of tumors were benign, and 20% were malignant. Preoperative NAB findings were compared with pathologic diagnosis of the surgically resected specimen in all cases. Forty-six of 63 aspirates from malignant tumors were correctly diagnosed by NAB, establishing a sensitivity at 73%. Two hundred forty-nine of 265 aspirates from benign tumors were correctly diagnosed by NAB, establishing a specificity at 94%. Overall accuracy was 90%. Diagnostic error or difficulty in clinically localizing the tumor to the salivary gland was encountered in 64 patients with parotid tumors and 12 patients with submandibular tumors. NAB correctly localized over 85% of these tumors to the salivary gland, thus enabling both immediate and correct decision-making concerning subsequent management to be undertaken.

Case report: A 47-year-old man was admitted with recurrent symptoms of dysarthria, diplopia, vertigo, and drop attacks. Workup revealed Ͼ90% stenosis of the left vertebral artery at its origin with poststenotic dilatation (Fig 1). The vertebral artery was 4 mm in diameter. The plaque appeared to have significant embolic potential. The right common femoral artery was accessed with short 9F sheath, and patient was anticoagulated with intravenous heparin (100 U/kg body weight). The left subclavian artery was cannulated using headhunter catheter. The catheter was advanced over the wire to mid brachial artery. Wire exchanged to stiff wire. MoMa flow reversal guide catheter (Medtronic, Minneapolis, Minn) was advanced over the stiff wire until the trailing balloon was engaged in the left subclavian artery. The leading balloon was positioned in left subclavian artery and kept deflated. The trailing balloon in left subclavian artery was inflated after
