Background: Bronchiectasis is characterized by chronic sputum production and complications such as hemoptysis and repeated infections. Even though some patients are cured by surgical resection of bronchiectatic lesions, most bronchiectasis patients can not be treated surgically because of multiple site involvement, and they are treated by medical measures such as postura1 drainage and antibiotics when indicated. Recently there have been some reports that low-dose longterm erythromycin treatment is effective on bronchiectsis, and it is well known that low-dose longterm erythromycin treatment is the treatment of choice in diffuse panbronchiolitis which is characterized by chronic sputum production and dyspnea. To evaluate the efficacy of erythromycin, we tried erythromycin on twenty five stable bronchiectasis patients for more than six months. Methods: We tried erythromycin 250 mg b.i.d. for more than 6 months. We checked respiratory symptoms, chest PA, spirometry, and side effects before treatment and after 3 and 6 months of treatment. Results: 1) 32% of the patients showed marked improvement of symptoms and PFT. 32% showed slight improvement of symptoms with little change of PFT, and 36% showed no change of symptoms and signs. 2) Analysis of the patients showing marked improvement revealed that most of them had diffuse bronchiectasis and paranasal sinus involvement. Conclusion: These results suggest that low-dose longterm erythromycin treatment can be tried on diffuse bronchiectasis patients with sinus involvement. And further studies will be followed on the mechanism of erythromycin in bronchiectasis.

A 9-year-old, castrated male Malamute dog was presented with chronic cough. On thoracic computed tomography, non-tapered and dilated peripheral bronchi were detected. Bronchoarterial ratio was about 2.2. The dilated bronchi appeared as a cluster of grapes especially in left cranial, left caudal and right middle lung lobe. Based on the computed tomographic findings, the diagnosis was made as the saccular type of bronchiectasis.

Background: The patient with bronchiectasis may have obstructive ventilatory impairment combined with mild restrictive ventilatory impairment due to fibrosis of surrounding lung parenchyme and pleural adhesions caused by chronic recurrent pulmonary infections. Since hyperinflation or emphysematous change can be occured in bronchiectasis, pulmonary functions such as lung volumes and diffusing capacity may also vary with associated emphysema. Methods: For the evaluation of lung volumes and diffusing capacity in bronchiectasis with respect to the anatomic types and severity of bronchiectasis, a total of 40 cases comprising 24 cases of tubular, and 16 cystic type of bronchiectasis were analyzed retrospectively. Correlation between lung functions and extent of bronchiectasis or associated emphysema detected in HRCT were also evaluated. Results: Vital capacity(VC) tended to decrease in cystic type than in tubular type. As the severity of bronchiectasis became serious, the VC were significantly reduced, whereas the total lung capacity(TLC), residual volume(RV) and its ratio to the total lung capacity(RV/TLC) had no significant difference. Lung clearance index(LCI) was significantly increased in cystic type than in tubular type, whereas the slope of phase III in single breath nitrogen curve($\triangle$N2/L) was not significantly changed regard to the type and severity of bronchiectasis. DLCO and DLCO/VA reflecting diffusing capacity were significantly decreased in cystic type and also as the severity of bronchiectasis became serious. The correlation coefficient of VC, DLCO and LCI with the extent of bronchiectasis were -0.322, -0.339 and 0.487, respectively, whereas other parameters were not significantly correlated with the extent of bronchiectasis. VC and DLCO correlated negatively with the extent of emphysema while RV, RV/TLC, LCI and $\triangle$N2/L correlated positively. Conclusion: These findings suggest that the reduction of VC and diffusing capacity or uneven distribution of inspired gas in bronchiectasis are related to both the extent of bronchiectasis and associated emphysema while increased residual volume be related to the extent of associated emphysema alone.

Background: Bronchiectasis is a irreversible disease, a lot of cases of which are associated with chronic bronchitis, pulmonary emphysema and bronchial asthma due to chronic recurrent pulmonary infection. Therefore, pulmonary functions in bronchiectasis may also vary with associated diseases or involved segments. Methods: For the evaluation of ventilatory dynamics in bronchiectasis with respect to the pathoanatomic types of bronchiectasis and the degree of dyspnea, a total of 93 cases comprising 45 cases of tubular, 30 saccular and 18 mixed type of bronchiectasis whose clinical diagnosis was confirmed by bronchography were analyzed retrospectively. They were also divided into two groups: those with Hugh-Jones dyspnea grade 1 & 2 (group I) and those with Hugh-Jones dyspnea grade 3 & 4 (group II). Pulmonary functions tested in this study were analyses of curves of forced expiratory volume and flow-volume, and determinations of maximal voluntary ventilation and closing volumes. Results: The results were as follows; 1) The vital capacity and parameters reflecting expiratory flow rate except PEF were significantly reduced in saccular and mixed type than that in tubular type of bronchiectasis. 2) In saccular and mixed type, the maximal voluntary ventilation tended to decrease while CV/VC tended to increase. 3) As the degree of dyspnea became serious, the involved segments were progressively increased. In contrast, ventilatory functions were significantly reduced in proportion to the severity of dyspnea. Conclusion: These findings suggest that in bronchiectasis, there be obstructive ventilatory impairment combined with mild restrictive ventilatory impairment, which becomes more prominent in saccular and mixed type and also as the degree of dyspnea progresses.

Bronchial artery aneurysm is a rare but life-threatening disease when it ruptures, and it requires prompt treatment to prevent from catastrophic ruptures. A 78-year-old woman was referred to our hospital to evaluate mediastinal massfound on chest computed tomography. We did a selective bronchial artery angiography and diagnosed as bronchial artery aneurysm. Aneurysmectomy with division of afferent and efferent arteries was performed through standard thoracotomy without cardiopulmonary bypass. The patient recovered uneventfully and was discharged on postoperative 8th day without any complications.

1) 천식 기관지 확장증에서는 기종상 음영이나 기관지가 확장된 상이 있고, 또한 미만성 범세기관지염 5예에서는 미세 반점상 음영이 전체 예에서 인정이 되었다. 2) 폐염에서는 기관지의 확장이나 점액이 고여 침윤음영이 전체 예에 나타나고 있었다. 한편, 간질성 폐염 29예에서는 반점상 음영(불균일 CT치의 상승과 내부에 작은 기관지 확장으로 작은 air상)이 보였다. 폐섬유증 19례에서는 기종상 농포상 음영이나 혈관 기관의 부정 확장, 반점상 음영이 15예로 79 %를 차지하고 있다. 만성 폐기종에서는 기종상, 다발성 농포상 음영, 고목상 혈관이 특징적인 소견이었다. 3) 속립성결핵에서는 작은 입상 음영, 폐결핵 15예에서는 공동 음영 7예, 원형의 융합음영 8예, 침윤음영, 다수의 석회화상, 혈관 기관의 부정 확장 등이 특징적이었다. Aspergillus증에서는 공동 음영 내부에 fungus ball이 보였다. 이상은 미만성 폐질환의 특징적인 CT의 이상 소견에 대해서 검토하였으나, 꼭 일치되는 것은 아니며, 기타 기초적 검사나 임상적인 경과관찰이 필요하였다. 끝으로, 대한방사선기술학회의 발전과 학회원 여러분의 건승을 기원합니다. 그리고 한국과 일본의 우호적인 학술교류가 지속되기를 희망합니다.
