Characteristics of Blunt Cerebrovascular Injury in Khon Kaen Hospital: A Descriptive Study

Introduction

Characteristics of blunt cerebrovascular injury in khon kaen hospital: a descriptive study. Explore characteristics of blunt cerebrovascular injury (BCVI) at Khon Kaen Hospital. Understand BCVI prevalence, in-hospital stroke, and mortality rates, stressing crucial early detection.

Abstract

Background: Evidence on blunt cerebrovascular injury (BCVI) remains limited. This study aimed to describe the characteristics of BCVI in a tertiary care referral hospital and trauma center in northeastern Thailand. Methods: This retrospective descriptive study was conducted in the trauma ward and trauma intensive care unit (TICU) at Khon Kaen Hospital from 2020 to 2025. The eligible criteria were the patients sustained blunt trauma and were diagnosed BCVI by computed tomography of 4 vessels of the neck (CTA neck). Baseline data were recorded, including injury characteristics, clinical signs symptoms, and risk factors following standard screening criteria including Denver and Memphis group. Potential endpoints including mortality and in-hospital stroke were also collected. Results: A total of 14 patients were included in this study. Most were male 71.4%. The mean age was 47.9±17.5 years. The mean injury severity score (ISS) was 18.9±7.0. The potential parameters for BCVI were severe TBI with GCS < 6 (28.6%) and stroke as a primary presentation (28.6%). Relevant CT findings suggestive of BCVI were cervical spine fracture (42.9%) and complex skull fracture, respectively (28.6%). Most of the patients were presented with total occlusion (grade 4) BCVI with prevalence of 42.9%. The locations of BCVI were equal between common carotid and vertebral arteries. There were 3 (21.4%) patients with in-hospital stroke and 28.6% in-hospital mortality. Median hospital cost was 96,884.5 [45,090.5, 268,775.5] baht. Conclusion: BCVI was prevalent in tertiary care referral hospital and trauma center. Serious in-hospital complications especially stroke and death were not uncommon. The best way to prevent complications is early detection with high index of suspicious.
