Interventional Radiology of salivary Gland Disease using balloon Catheter

在涎腺导管球囊扩张治疗前，探讨梗阻性涎腺炎。本文报告梗阻性涎腺炎10例。调查结果如下：1)绝大多数（9 / 10）的梗阻发生在咬肌前缘部分。2)病程并不总是与病情严重程度相关。3)唾液腺外周导管损伤与造影剂排泄程度相关。从1)的结果来看，扩张术可以适用于大多数梗阻性涎腺炎。在以上结果的基础上，我们采用PTCA球囊导管对2例梗阻性涎腺炎进行球囊扩张治疗。在第一个病例中，尽管疼痛轻微减轻，扩张治疗对梗阻性涎腺炎没有明显的效果。这种不满意的原因被认为是由于唾液管弯曲导致球囊导管输送不足。第二例，虽然球囊尖端到达梗阻部分，但我们对梗阻性涎腺炎也没有效果，因为扩张直径不足以治疗，从两例的结果来看，我们必须改进仪器，特别是导管的强度和球囊的扩张直径。

Before the balloon dilation therapy of duct of salivary gland, we investigate the obstructive sialoadenitis. Ten cases of obstructive sialoadenitis were investigated. Results of investigation were listed below.1) Most (9 of 10) of the cases, obstruction arise from part of anterior border of masseter muscle.2) Duration of illness was not always correlated with gravity of patient's illness.3) Damage of peripheral duct of salivary gland was correlated with degree of excretion of contrast media.From the result of 1), it was thought that dilation therapy could be adapted to most of obstructive sialoadenitis.On the basis of above results, we performed two cases of balloon dilation therapy of obstructive sialoadenitis using PTCA balloon catheter. In first case, in spite of slight reduction of pain, dilation therapy had no apparent effect on obstructive sialoadenitis. The reason of such unsatisfactory was thought to be result from insufficient delivery of balloon catheter owing to curvature of salivary duct. In second case, although apex of balloon reached the portion of obstruction, we also had no effect on obstructive sialoadenitis, because dilation diameter was not enough for treatmentFrom the results of two cases, it became clear that we must improve the instrument, especially both strength of catheter and dilation diameter of balloon.
