A 39-year-old-woman was treated successfully by a combination of endobronchial and bronchial artery embolization for massive hemorrhage originating from the posterior segment of the right upper lobe. Endobronchial embolization was performed using a silicone spigot placed via flexible bronchoscopy in order to prevent alveolar inundation preceding and during the time of bronchial artery embolization. Massive hemorrhage is a rare and severe condition associated with a high mortality that requires rapid intervention and management. We describe a case that emphasizes the efficacy of a multidisciplinary approach including the use of a new bronchoscopic technique.
Stenting is a relatively new option in the management of superior vena cava obstruction (SVCO), but available data often concern non-malignant and/or various malignant diseases.The aim of this study was to assess the efficacy of vascular stenting as a first-choice treatment in SVCO in the exclusive setting of NSCLC.Retrospective study of NSCLC patients with SVCO treated in the past year. Demographic data, disease characteristics, etiologic and palliative treatment (use of vascular stenting) were recorded as well as treatment outcome and survival.17 patients were recruited. Eight had vascular stenting while 9 did not. Except for stenting, there was no difference between the two groups (median age 54 years; 80% men; 53% stage IIIB and 47% stage IV). Stenting (median length 60 mm) achieved complete resolution of SVCO more frequently (75 vs. 25%, p = 0.05) and faster (2 vs. 21 days, p = 0.002) without immediate or delayed complication. All patients with stents received anticoagulation therapy. Relapse rate after complete response (33 g, 50%, p = 0.6) was lower and time to relapse (6.5 g, 2 months) was longer for patients undergoing stenting, without reaching statistical significance. Median overall survival was not statistically different (8 and 5 months, p = 0.06).This study demonstrated the effectiveness of vascular stenting for SVCO in NSCLC patients. The high response rate, quick effect and safety of vascular stenting make this palliative treatment a candidate as a potential standard procedure. The results, however, must be confirmed in a prospective randomized trial including quality of life assessment.
Background In some patients with acute respiratory distress syndrome, the prone position is able to improve oxygenation, whereas in others it is not. It could be hypothesized that the more opacities that are present in dependent regions of the lung when the patient is in the supine position, the better the improvement in oxygenation is observed when the patients are turned prone. Therefore, we conducted a prospective study to identify computed tomographic scan aspects that could accurately predict who will respond to the prone position. Methods We included 46 patients with acute respiratory distress syndrome (31 responders and 15 nonresponders). Computed tomographic scan was performed in the 6-h period preceding prone position. Blood gas analyses were performed before and at the end of the first 6-h period of prone position. Results Arterial oxygen partial pressure/fraction of inspired oxygen increased from 117 +/- 42 (mean +/- SD) in the supine position to 200 +/- 76 mmHg in the prone position (P < 0.001). There were 31 responders and 15 nonresponders. There was a vertebral predominance of the opacities (P < 0.0001). However, there was no difference between responders and nonresponders. When only the amount of consolidated lung located under the heart was evaluated, there was more consolidated tissue under the heart relative to total lung area in nonresponders than in responders (P = 0.01). Conclusions There are no distinctive morphologic features in the pattern of lung disease measured by computed tomographic scanning performed with the patient in the supine position that can predict response to the prone position.
