Outcomes of Blunt Suprahepatic Vena Cava Injuries: A Retrospective Study from a Single Trauma Center in Korea.

Background/

Objectives

Blunt suprahepatic inferior vena cava (SHIVC) injury is a rare and highly lethal condition associated with severe thoracoabdominal trauma. This study describes the clinical characteristics and outcomes of SHIVC injuries treated at a single institution.

Methods

We retrospectively reviewed patients with blunt SHIVC injury treated between January 2014 and September 2023. Demographics, injury characteristics, management strategies, and outcomes were analyzed descriptively. The primary outcome was in-hospital mortality. Given the small sample size, statistical analyses were exploratory.

Results

Ten patients were identified (mean age: 47 ± 17 years; mortality: 40%; ISS: 43 ± 19). On admission, 50% presented with systolic blood pressure < 90 mmHg and a mean Glasgow Coma Scale score of 7 ± 5. Non-survivors had lower systolic blood pressure (70 ± 12 vs. 115 ± 34 mmHg, p = 0.05), lower GCS scores (3 ± 0 vs. 9 ± 5, p = 0.02), and worse base excess (-20.1 ± 5.8 vs. -7.8 ± 7.1) than survivors. Surgical intervention was performed in 9 patients, while 1 was managed nonoperatively. Common associated injuries included right atrial injury (70%), liver injury (50%), and diaphragm injury (30%). Four patients received intraoperative circulatory support; two treated with cardiopulmonary bypass survived, whereas those treated with extracorporeal membrane oxygenation died. No definitive conclusions can be drawn regarding treatment effectiveness due to the limited sample size.

Conclusions

Outcomes appear strongly influenced by initial physiological status and injury severity. This study is descriptive and hypothesis-generating; further multicenter studies remain warranted to define optimal management strategies.
