[Video-assisted thoracoscopic surgery in spontaneous hemopneumothorax]

A case of hemothorax following seat-belt injury with a bulla in the apex of the lung: a subtype of spontaneous hemopneumothorax

We experienced a case of a subtype of spontaneous hemopneumothorax caused by external forces associated with a seat-belt injury. A female aged 39 years sustained a minor collision with an oncoming car while she was driving. Although pneumothorax was not detected, hemothorax and bleeding from the area surrounding the subclavian artery were observed on contrast-enhanced chest computed tomography (CT). After confirming continuous bleeding into the thoracic cavity after superselective arterial embolization, we performed emergency open surgery. We found a bulla in the apex of the lung, and the thoracic stump of the bulla was considered the source of bleeding. In this case, the direct cause of hemothorax was considered to be the external force associated with the seat-belt injury. When a bulla in the apex of the lung and continuous bleeding are both observed on CT, spontaneous hemopneumothorax should be suspected, necessitating open chest surgery in cases where pneumothorax is not observed.

Video-assisted thoracic surgery for spontaneous haemopneumothorax

BACKGROUND AND OBJECTIVE

The aim of this study was to review the treatment options for spontaneous haemopneumothorax (SHP) by video-assisted thoracoscopic surgery (VATS).

METHODS

Records from 16 patients (14 male, age 16-38 years, mean age 26.1 years) with prominent SHP (blood loss over 400 cc in the first 24 h) undergoing VATS from July 1994 to December 2005 and treated by one thoracic surgeon in four medical centres or community hospitals of North and Mid-Taiwan were reviewed retrospectively.

RESULTS

Thirteen patients (81.3%) were identified to have a prominent bleeding source intraoperatively. Torn engorged vessels from the parietal pleura to adjacent bullae were found in nine patients, and bleeders adjacent or over the parietal part of the adhered pleura were found in the other four. Ruptured bullae/blebs or air leakage were found in 14 (87.5%). All underwent removal of intrapleural blood clot, control of bleeders and their bullae/blebs were resected through three-port VATS (n = 13, 81.2%) or mini-thoracotomy and VATS (n = 3, because of unstable vital signs or conversion because of dense adhesion). Mechanical or chemical pleurodesis was carried out in all patients. The mean operative time was 53.8 +/- 21.7 min. There was no postoperative mortality. However, recurrent bleeding requiring reoperation occurred in one patient, and one other patient had a prolonged air leakage (>7 days) postoperatively and recovered spontaneously. The mean duration of chest tube drainage was 3.8 days and the median follow-up period was 3.2 years.

CONCLUSION

SHP complicated by severe bleeding is a surgical emergency. VATS is a reasonable treatment for patients with SHP.

Spontaneous hemopneumothorax: an overlooked life-threatening condition

Spontaneous hemopneumothorax is a rare clinical entity. A large spontaneous hemopneumothorax is life-threatening, and mortality increases with delayed recognition and intervention. The initial chest radiography and the amount of blood drained from the inserted chest tube frequently underestimates the actual blood loss from the active bleeder around the ruptured apical bullae, leading to failed recognition of a potentially life-threatening condition until unexpected hemodynamic collapse develops. We report 2 cases of spontaneous hemopneumothorax to emphasize the importance of early recognition and prompt surgical intervention by video-assisted thoracoscopic surgery (VATS).
