Angiographic experience with chemodectomas in 21 patients is reviewed. Arterial supply was identified from the vertebral artery, the internal carotid artery, and branches of the external carotid artery. A striated cephalad extension from a cervical chemodectoma (five patients) is believed to represent arterial supply to tumor in vein. In two patients, internal and external carotid arteriograms did not opacify important arteries originating near the carotid bifurcation. Retrograde filling of sigmoid sinus (four patients), tumor mass in jugular vein (two patients), and arteriovenous shunting (nine patients) were observed during the venous phase. Thorough angiogra phy is essential for evaluation of chemodectomas of the head and neck.
回顾了21例化学感受器瘤的血管造影经验。确定肿瘤的动脉供应来自椎动脉、颈内动脉和颈外动脉分支。5例颈部化学感受器瘤出现向头侧的条纹状延伸，被认为代表肿瘤在静脉内的动脉供应。2例患者的颈内和颈外动脉造影未使起源于颈动脉分叉附近的重要动脉显影。在静脉期观察到4例乙状窦逆行充盈、2例颈静脉内肿瘤团块和9例动静脉分流。全面的血管造影对于评估头颈部化学感受器瘤至关重要。
