BACKGROUND The authors tested the hypothesis that administration of vaporized perfluorohexane may attenuate ventilator-induced lung injury. METHODS In isolated, perfused rabbit lungs, airway pressure-versus-time curves were recorded. At baseline, peak inspiratory pressure and positive end-expiratory pressure of mechanically ventilated lungs were set to obtain straight pressure-versus-time cur...

Large aneurysms of the ascending aorta occasionally cause severe hemodynamic disturbance by compression. We describe the case of an 18-yr-old man who presented with dyspnea and developed hemodynamic collapse during computed tomography scanning. Computed tomography during resuscitation revealed that the aneurysm was compressing both the right pulmonary artery and the left bronchus. Emergency sur...

Free full text available from www.ijccm.org A b st ra ct We present a rare case of unexpected sudden death in a young woman with undiagnosed sickle disease. The provocative factors for the terminal events were excessive exercise in the form of trekking, urinary infection, and emotional stress .the sudden cardiovascular collapse could have resulted from acute pulmonary hypertension resulting fro...

A case is described of tracheobronchomegaly progressing to extensive tracheomalacia, complicated by episodic choking, recurrent pulmonary infections, and irreversible hypercapnic respiratory failure. A Y-shaped tracheobronchial stent was placed endoscopically to splint the trachea open, with excellent clinical and physiological improvement. New stent designs may provide long term palliation in ...

During a long-term follow-up of 10 to 17 years on 383 children aged 2 months to 15 years suffering from primary pulmonary tuberculosis with consolidation-collapse of lung segments, apparent calcification was noted to have disappeared in whole or in part from the lungs and/or lymph nodes of 68 children. This finding was most common in those under 6 years of age on entry to the study, 23-40, comp...

Benign schwannoma is the most common neurogenic tumor in the mediastinum. Mediastinal benign schwannomas are most often asymptomatic and rarely accompanied by bloody pleural effusion. In the clinical analysis of 7 cases of pulmonary schwannomas, pleural effusion, and blood invasion were evident in 3 patients with malignant schwannoma. Herein, we report a rare case of giant, benign schwannoma pr...

Massive pulmonary embolism (PE), an uncommon event in the perioperative period, is a major challenge to anesthesia management. Massive PE is often associated with an unexpected hemodynamic collapse and severe desaturation without other characteristic changes. It is difficult to make a rapid diagnosis during the perioperative period, especially under general anesthesia. We present a rare case of...

Plombage, a variant of collapse therapy for patients with pulmonary tuberculosis that uses a variety of foreign materials, was undertaken until the 1950s before the invention of effective antimicrobial therapy. Complications related to previous plombage procedures are not uncommon. Management of these complications can be challenging. We report a patient presenting with extrusion of plombage 59...

Thrombus-in-transit is not uncommon in pulmonary embolism but Right Heart Transvalvular Embolus (RHTVE) complicating this is rare. A 54-year-old obese male with recent hospitalization presented with severe dyspnea and collapse. Initial investigations revealed elevated d-dimer and troponin. CTA showed saddle pulmonary embolus and bedside echocardiogram revealed right ventricular (RV) pressure ov...

A V/Q lung scan was obtained in a patient with LLL collapse who was receiving IPPV and PEEP. This revealed absent ventilation and hyperperfusion to the collapsed lobe. After a reduction in PEEP from 12 to 5 cm H O, a repeat V/Q scan showed a more even distribution of pulmonary perfusion. Arterial hypoxemia improved. (Chest 1991; 99:1034-36) D espite continuing controversy regarding the most app...
