RESUMEN

Micropigs are the most likely source animals for xenotransplantation. However, an appropriate method for evaluating the lung of micropigs had not been established. Therefore, this study was performed to evaluate the feasibility of 64-channel multi-detector row computed tomography (MDCT) to measure the diameter of the pulmonary arteries and the lung volume in micropigs. The mean diameters of the trachea, and left and right bronchi were 1.6 +/- 0.17, 1.18 +/- 0.14, and 1.1 +/- 0.11 cm, respectively. The mean diameters of the main, right, and left pulmonary arteries were 1.38 +/- 0.09, 1.07 +/- 0.26, and 0.98 +/- 0.13 cm and the diameters of right, left, and common inferior pulmonary veins were 0.97 +/- 0.20, 0.76 +/- 0.20, and 1.99 +/- 0.26 cm, respectively. The mean lung volume was 820.3 +/- 77.11 mL. The data presented in this study suggest that the MDCT may be a noninvasive, rapid, and accurate investigational method for pulmonary anatomy in living lung donors.

RESUMEN

We present the multidetector CT findings with a pathologic correlation for the case of a solitary fibrous tumor located in the trachea. The MDCT revealed a well-circumscribed intraluminal mass arising from the trachea, with strong nodular enhancement in the periphery of the mass. The enhancement pattern of the mass corresponded histopathologically to a focal hypocellular area in the center and prominent blood vessels along the periphery of the mass. We also present volume-rendered and virtual bronchoscopic images of this rare submucosal tracheal tumor.

RESUMEN

A congenital coronary artery fistula is a rare condition, which is an abnormal communication of the coronary artery with the ventricles or atriums or the pulmonary artery. A case of 69 year-old man, complaining of recent aggravating chest pain for 5 months is reported. The coronary angiography shows coronary artery-pulmonary artery fistula. Multidetector row CT shows coronary artery-pulmonary artery fistula combined with aortopulmonary fistula via common channel and the fistulas were surgically ligated.

RESUMEN

PURPOSE: To evaluate the accuracy and availability of Multidetector-Row Computed Tomography (MDCT) and Color Doppler Sonography as a method for making an early diagnosis of DVT after joint arthroplasty. MATERIALS AND METHODS: A total of 71 cases (63 patients) were selected. 32 cases (32 patients) underwent a THRA and 39 cases (31 patients) underwent a TKRA between April 2004 to August 2004. All cases underwent both Color Doppler Sonography and MDCT, before and after surgery. No prophylactic medications for DVT were given. Patients who previously had DVT or pulmonary embolism or a medication history of anticoagulation therapy were excluded. RESULTS: DVT was found by MDCT in 33 cases (46.5%) and by Color Doppler Sonography in 15 cases (21.1%). In the 33 cases of DVT diagnosed by MDCT, 24 cases developed in the calf vein, among them, only 4 cases were positive and remaining 20 were negative in Color Doppler Sonography. In the 15 cases of DVT diagnosed by Color Doppler Sonography, 13 cases were positive and only 2 cases were negative in MDCT. CONCLUSION: MDCT is effective in diagnosing DVT after joint arthroplasty in terms of the objectivity, efficacy and accuracy.
