This study was conducted in 47 patients with biopsy-proven cancer of the head or neck. These patients each had an intra-arterial infusion tube inserted retrogradely. Positioning in the infusion tubes had been determined by staining of the mucocutaneous area of the malignant lesion under observation with injection of blue dye. Digital subtraction angiography (DSA) was performed from the infusion tube. DSA demonstrated that infusion tubes were in the correct position in 26 patients (55%), and in an incorrect position in 21 patients (45%). The infusion tubes of all patients with cancer of the maxillary sinus were in the correct position. However, the majority (54%) of infusion tubes in patients with cancer of the tongue were in an incorrect position. Observation of arterial flow from the infusion tube using DSA should be made in all patients with head or neck cancer in order to avoid the potential complications of intra-arterial chemotherapy.
本研究对47例经活检证实为头颈部癌症的患者进行。这些患者均逆行插入了动脉内输液管。输液管的定位是通过向观察到的恶性病变的黏膜皮肤区域注射蓝色染料进行染色来确定的。从输液管进行数字减影血管造影（DSA）。DSA显示，26例患者（55%）的输液管位置正确，21例患者（45%）的输液管位置不正确。所有上颌窦癌患者的输液管位置均正确。然而，舌癌患者中大多数（54%）的输液管位置不正确。为避免动脉内化疗的潜在并发症，应对所有头颈部癌症患者使用DSA观察输液管的动脉血流情况。
