Background Psoas hematoma rarely occurs in patients with spondylolisthesis who undergo posterior lumbar interbody fusion (PLIF) surgery. Case presentation Here we reported a case of a 57-year-old male patient diagnosed with spondylolisthesis who underwent PLIF at the local hospital. Seven days post-surgery, abdominal pain occurred, and the pain in the right lower limb gradually increased. The computerized tomography (CT) indicated a formation of hematoma around the psoas muscle. Digital-subtraction angiography (DSA) suggested a vascular injury, a rupture of the right segmental artery of the lumbar vertebral level 4. The patient then received DSA vascular embolization, after which the lower lumbar segmental artery active bleeding was stopped. One month after discharge, the abdominal hematoma was gradually absorbed, and the pain in the waist, leg, and abdomen disappeared. Conclusion Symptoms such as abdominal pain, abdominal distension, and exacerbation of lower limb pain, may suggest the occurrence of psoas hematoma after PLIF. DSA vascular embolization is suggested as the first treatment approach for this type of complication.

Purpose: The efficacy and safety of topical fibrin sealant (FS) compared with tranexamic acid (TXA) to reduce blood loss after total hip arthroplasty (THA) is not clear. A meta-analysis was conducted to evaluate the efficacy and safety of topical FS versus topical or intravenous TXA for treatment of Method: We searched electronic databases, including PubMed, EMBASE, and the Cochrane Library to identify studies up to March 2020. The references included in articles were also checked for additional potentially-relevant studies. The language of publication was limited to English. The endpoints included the mean difference (MD) of blood loss, hemoglobin value, and odds ratios (ORs) of transfusion requirements and thrombotic events. Our meta-analysis was performed according to the Guidelines of the Cochrane Reviewer's Handbook and the PRISMA statement. The data of the included studies were analyzed using RevMan 5.3.Results: A total of four studies (two randomized controlled trials and two non-randomized controlled trials) met the inclusion criteria. Our meta-analysis demonstrated that TXA administration led to significantly different outcomes in terms of transfusion rate (RD = -0.12, 95% CI (-0.23, -0.00), P = 0.05, I2 = 74%) and postoperative hemoglobin levels (WMD = -0.47, 95% CI (-0.74, -021), P = 0.0005, I2 = 3%) compared with topical application of FS in patients undergoing THA. No significant difference was seen in total calculated blood loss (WMD = -86.22, 95% CI (-99.13, -73.31), P < 0.00001, I2 = 96%) or complication rate (RR = 0.98, 95% CI (-99.13, -73.31), P = 0.45, I2 = 0%) between the two groups.Conclusions: TXA administration can effectively decrease the transfusion rate and result in higher postoperative hemoglobin levels without increasing the rate of infection.
