Traumatic hemothorax is a common complication of chest trauma; however, the timeline for its resolution, even with chest tube thoracostomy, remains unclear.
To determine the time to resolution of the hemothorax to ensure safe discharge based on chest radiography (CXR) findings.
A retrospective observational study was conducted at Hamad General Hospital, Qatar, from June 2014 to October 2019, including all patients with hemothorax diagnosed via computed tomography (CT) following chest trauma. Based on the initial imaging study, the hemothorax was divided into right, left, and bilateral.
The study included 422 patients. Of the total, 57.82% (n = 244/422) resolved their hemothorax within three days of admission. Among these, 44 patients required chest tube insertion (CTI) and 200 were cleared without it. Between days 3 and 7, an additional 16.83% (n = 71 /422) of cases were resolved, of which 28 required chest tubes. By days 8 to 14, another 11.37% (n = 48/422) were cleared, with 15 patients requiring chest tubes. After 14 days, 13.98% (n = 59/422) of patients still had hemothorax, 14 of whom required CTI.
This study showed that a subset of patients continued to experience retained hemothorax despite early tube thoracostomy. Patients with a larger hemothorax, particularly on the left side, showed prolonged resolution times. Regular imaging such as CXR or CT is recommended for up to 14 days post-intervention. After this period, outpatient follow-up is generally safe, although some patients may still have a persistent hemothorax beyond two weeks.
Core Tip: Traumatic hemothorax often requires chest tube insertion for resolution. However, the duration of follow-up for small or retained hemothorax (RH) remains uncertain. We aimed to determine the appropriate follow-up duration by using chest radiography (CXR) or computed tomography (CT). The study included 422 patients. Of these, 75% resolved their hemothorax within 7 days and 11% on days 8 to 14 post-admission. A subset of patients continued to experience RH despite early tube insertion. Patients with larger hemothoraces, particularly on the left side, exhibited prolonged resolution times. Regular imaging using CXR or CT is recommended for up to 14 days post-intervention.
