Pulmonary Atelectasis*

The authors have experienced a case of entire lung collapse on the right side which appeared after upper abdominal operation under endotracheal general anesthesia. It has been rarely reported in the literature.

Accessory fissures serve not only as natural barriers against infection but also help in localizing any focal pulmonary parenchymal diseases and in distinguishing pleural from parenchymal diseases. Knowledge of these fissures might be useful in differentiating unusual forms of atelectasis or consolidation occuring adjacent to the fissure. Left minor fissure (LMF) is a kind of unusual accessory fissures of the left lung, which separates adjacent segments of the upper lobe as clefts of various depths lined by two layers of visceral pleura. In this study, 4 cases of LMFs found in the left upper lobe during a routine dissection of 36 cadavers were observed. Of the 4 cases, 3 cases were true LMFs which located between the anterior segment of the upper lobe and superior segment of lingula, and 1 case was considered as left azygos fissure. Among the true LMFs, 2 LMFs coursed horizontally and 1 LMF coursed upward obliquely along the costal surface. The depth of LMFs was 0.5~1.2 cm and the length was 5~8 cm.

The characteristic radiographic and CT findings of Iobar atelectasis are well known. However, Iobar atelectasis is a dynamic process, and atypical presentations may occur due to a number of different causes. Familiarity with the various typical and atypical radiographic findings of Iobar atelectasis is important for correct diagnosis. The aim of this manuscript is to illustrate the spectrum of radiographic findings of Iobar atelectasis and to correlate the radiographic findings with the CT findings. The review will illustrate examples of typical and atypical Iobar atelectasis, including combined Iobar atelectasis, peripheral Iobar atelectasis, migrating Iobar atelectasis, rounded atelectasis involving the entire lobe and Iobar atelectasis mimicking paravertebral and mediastinal masses.

To evaluate late change of irradiated lung, a total of 60 rats was irradiated on right lungfield with a single dose of 2000 rads using Co-0 teletherapy unit. Follow-p roentgenographic and histopathologic study was performed three, six and twelve months after irradiation in each group of 20 rats. The results were as follows: 1.Chest roentgenographic findings in the order of frequency were pneumonic consolidation, atelectasis, and pleural effusion in 3-onth follow-p group; atelectasis, fibrostreaky infiltration, and pneumonic consolidation in 6-onth follow-p; and normal, and normal, and atelectasis in 12-onths follow-p group. 2. Main histopathological findings were alveolar and interstitial exudates, and diffuse infiltration of inflammatory cells in 3-onth follow-p group; thickening of interstitium and vascular wall in 6-onth follow-p group; and interstitial fibrosis in 12-onth follow-p group.

BACKGROUND: Compared with blockers mounted on the endotracheal tube, (a conjugated blocker), studies about blockers that are independent of a single-lumen tube, (a separated blocker) are rare. This study's object was to find several characteristics about these new blockers. METHODS: We compared the peak and plateau airway pressures in intubated patients (n = 30) with, (group EB) and without, (group E) blockers. We measured the depth of the blockers and the pressures of the balloon of the blockers. Balloon pressures were measured twice outside and inside of the E-tube with 7 ml of air. All of these measurements were done in the supine position with 1 L/min flow rate. The frequency of malposition, the score of the lung collapse, and bronchial mucosa change were checked thereafter. RESULTS: The peak airway pressures of group EB were significantly higher than those of group E (p < 0.05). However, the plateau pressures of both groups were not different. The depth of the blockers was 52.0 +/- 1.8 cm, and the balloon pressures of the blockers were 124 +/- 22 and 139 +/- 20 mmHg, respectively. Six patients needed additional bronchoscopy because of malposition. The lung collapse score was good in 17 patients, fair in 10 patients, and poor in 3 patients. There was not any severe bronchial mucosa damage. CONCLUSIONS: Understanding the characteristics of these new blockers, we can consider the use of them in some situations in which the use of a double-lumen tube is impossible or inconvenient.
