Unilateral flooding of the lung after intubation with a double-lumen tube makes intraoperative sonography of the lung during video-assisted thoracoscopic surgery possible. After flooding with 15 ml/kg, the arterial partial oxygen pressure (with FiO2=1.0) is higher than that in total atelectasis by about 100 mmHg, while it is only slightly less than that(More)
A sonographic examination of the lung has so far been impossible because of sound reflection. In conjunction with video-assisted thoracoscopic surgery, lung sonography would be helpful to make up for the lack of direct palpation. Animal experiments with pigs were performed to find out whether lung sonography becomes possible following bronchoalveolar(More)
PURPOSE To evaluate the use of interventional procedures for treating complications following endovascular repair of aortic aneurysms. METHODS Fifty-five patients (49 men; mean age 67.5 years) underwent endoluminal stent-graft repair of traumatic (n = 4) or arteriosclerotic (n = 51) aortic aneurysms in the thoracic (n = 3) or infrarenal (n = 52) aorta.(More)
Soft-tissue mobilization (STM) is a system of manual techniques employing low-load, long-duration forces applied in approximation, traction, and torsional vectors to improve mobility between overlying and adjacent connective tissue layers throughout the body. The purpose of this article is to present the theory of STM as related to the properties of wound(More)
The paper represents the results of the mediastinoscopy in 135 cases of Boeck's sarcoid. The frequent formation of keloid's in the scar of the mediastinotomy is emphasized. The histological examinations of the scar keloid's after mediastinoscopy are compared with histological examinations of scars after resections of the thyroid glands. The possible reasons(More)
Unilateral flooding of the lung after intubation with a double-lumen tube enables intraoperative sonography of the lung tissue. The flooding restricts the pulmonary blood stream of the flooded lung in a relevant degree and thus reduces the right-to-left shunt volume. The deficient perfusion of the lung tissue during the flooded phase might cause capillary(More)
Up to 50% of the results of autofluorescence bronchoscopy (AF) of histologically benign lesions are false-positive. For better differentiation of such lesions we have used comparative genomic hybridization (CGH). We studied biopsy material from 47 patients by CGH. For a comparison of findings, the patients were grouped as follows: Group 1, patients with(More)
One-sided fluid flooding of the lung after intubation with a double-lumen tube facilitates pulmonary sonography during surgery. Arterial blood pressure, cardiac index, and heart rate remained unchanged during one-lung fluid flooding in healthy animals. The arterial PO(2) was greater by about 100 mmHg after flooding one lung with 15 ml/kg fluid and(More)
