Objective: To explore the prognostic significance of hidden blood loss in total hip arthroplasty.
Methods: From May 2008 to July 2009, Harris hip score was used to evaluate the functions of 71 patients undergoing single side total hip arthroplasty (including 47 males and 24 females with a mean age of 68.3 years, ranged from 48 to 75 years). The blood loss in the operation was analyzed to study the correlation between hidden blood loss and the functional rehabilitation.
Results: All 71 patients undergoing THA were involved in the result analysis. The mean total blood loss was 1473 ml and the hidden blood loss was 545 ml (37%). Hidden blood loss significantly correlated with functional rehabilitation (P = 0.001), but there were no correlations between functional rehabilitation and age, gender, operative limb of patients (P = 0.067, 0.527, 0.926, 0.072).
Conclusion: Hidden blood loss maybe a useful prognostic information contributing to the functional rehabilitation of total hip arthroplasty.

Patients with intracranial aneurysms (IA) undergoing endovascular treatment face varying risks and benefits when tirofiban is used for thromboprophylaxis during surgery. Currently, there is a lack of high-level evidence summarizing this information. This study aims to conduct a systematic review and meta-analysis to evaluate the efficacy and safety of tirofiban during endovascular treatment of IA.

Purpose: To comprehensively compare the diagnostic ability and inter-reader agreement of magnetic resonance imaging (MRI) findings for predicting massive hemorrhage after cesarean section in patients with placental malposition, aiming to identify the most reliable and objective indicators.
Methods: Totally, 148 consecutive patients with placental malposition underwent MRI and cesarean section at our hospital between January 2014 and July 2021. The patients were divided into massive and non-massive hemorrhage groups.

Background: Laparoscopic liver resection (LLR) is a surgical procedure with varying degrees of difficulty depending on tumor status and surgical technique. Therefore, we aimed to evaluate the relationship between surgical difficulty levels and outcomes of LLR, particularly portal vein thrombosis (PVT).
Methods: We performed LLRs in 214 patients between January 2009 and December 2022.

Background: Acetylsalicylic acid (ASA) has been used in reconstructive microsurgery since the inception of the field. However, when compared to placebo groups, its efficacy is not confirmed. In our study, we hypothesize that the utility of ASA postoperatively in microvascular surgery is not associated with improved outcomes.

Background: Early literature on the Woven EndoBridge (WEB) device reported 80-90% adequate aneurysm occlusion but low complete occlusion (40-55%). It is uncertain whether residual or recurrent aneurysms require re-treatment to prevent future rupture.
Objective: To systematically review the literature to meta-analyze occlusion and complication rates after re-treatment of these aneurysms.
