Prevalence and clinical characteristics of Terson syndrome among survivors of aneurysmal subarachnoid hemorrhage: a nationwide study in Japan
摘要
To investigate the characteristics of Terson syndrome (TS) among survivors of aneurysmal subarachnoid hemorrhage (aSAH).
Study designRetrospective study
MethodsUsing the Japanese Diagnosis Procedure Combination database, we identified patients diagnosed with aSAH at admission between July 1, 2010 and March 31, 2023 in Japan. The prevalence of TS in aSAH survivors was examined, along with comparisons of patient backgrounds between survivors with TS and those without TS. We compared the characteristics and outcomes in patients with TS who underwent vitrectomy with those in patients who did not, and analyzed the laterality of the surgery.
ResultsAmong 143,058 patients with aSAH, 104,576 (73.1%) survived. TS was diagnosed in 860 (0.8%) survivors. The patients with TS were younger (mean [standard deviation, SD] age: 53.3 [11.4] vs 64.0 [14.6] years) than those without TS. Among the patients with TS, 243 (28.3%) patients underwent vitrectomy during hospitalization, with a median interval of 38 days from admission to surgery. Of the patients with TS who underwent vitrectomy, 160 (66.4%) and 81 (33.6%) patients underwent unilateral and bilateral vitrectomy, respectively.
ConclusionIn this retrospective study, the prevalence of TS among aSAH survivors was less than 1%. Vitrectomy was performed in approximately one-third of the patients with TS, with one-third of these patients undergoing bilateral surgery during hospitalization.
