Perioperative Blood Loss

Surgery of long bone metastases is associated with a significant risk of perioperative blood loss, which may necessitate blood transfusion. Successful embolization (> 70% obliteration of vascularity) can be achieved in 36–75% of cases. The reported rate of embolization-related complications is 0–9%. Three out of six level III evidence studies showed a reduction in perioperative blood loss and/or blood transfusion requirement after preoperative embolization of renal cell carcinoma metastasis in long bones; three out of six studies did not. One level III evidence study did not show a reduction in perioperative blood loss and/or transfusion requirement after preoperative embolization of hepatocellular carcinoma metastases in long bones. There were no studies found that support preoperative embolization of thyroid metastases or other frequent long bone metastases (e.g. mamma carcinoma, lung carcinoma, or prostate carcinoma). The clinical level of evidence of the studies found is low and randomized studies taking into account primary tumour, location of metastases and type of surgery are therefore desired.

We described a patient with symptomatic giant hepatic hemangioma (GHH) treated with laparoscopic guided percutaneous microwave ablation (MWA). A 58 years’ old woman was referred to our hospital who presented with upper abdominal distension and appetite loss for more than 1 year. The medical history included untreated multiple hepatic hemangiomas (HH) that had been detected 13 years ago and hypertension for more than 12 years. Initial laboratory tests revealed D-dimer mild increase and negative tumor markers. Magnetic resonance (MR) imaging demonstrated multiple nodules of different sizes in the liver and the largest lesion was located on the left lobe (longest diameter 12.8 cm), which replaced the whole enlarged left lobe and compressed the gastric body and inferior vena cava. Contrast-enhanced ultrasound (CEUS) and contrast-enhanced MR imaging both showed the typical enhancement pattern of hemangioma and abnormal perfusion was seen in the surrounding liver parenchyma. With the laparoscopy guidance, we performed microwave ablation till the whole tumor was seen atrophy. The total operation duration was 2 hours, with intra-operative blood loss less than 20 ml. The post-operative course was uneventful. The patient was discharged 3 days after the operation. Abdominal distension decreased, appetite improved, blood pressure controlled at normal level after the operation. MR revealed significant volume reduction of the tumor after the operation.

Background and Objectives: The purpose of this study was to evaluate the feasibility, safety and efficacy of microwave ablation (MWA) in combination with open surgery nail positioning for the treatment of fractures or impending fractures of long bone metastases. Material and Methods: Eleven patients (four men, seven women) with painful bone metastases of the humerus, femur or tibia with non-displaced fractures (one case) or impending fractures (10 cases) underwent open MWA in combination with osteosynthesis by locked nail positioning. Pain intensity was measured using a VAS score before and after treatment. CT or MRI were acquired at one month before and 1, 3, 6, 12 and 18 months after treatment. Results: All procedures were successfully completed without major complications. The level of pain was significantly reduced one month after treatment. For the patients with humerus metastases, the complete recovery of arm use took 8 weeks, while for the patients with femoral metastases the complete recovery of walking capacity took 11 weeks. The VAS score ranged from 7 (4–9) before treatment to 1.5 (0–2.5) after treatment. During a mid-term follow-up of 18 months (range 4–29 months), none of the patients showed tumor relapse or new fractures in the treated site. Two patients died due to tumor disease progression. Conclusion: Results of this preliminary study suggest that combined MWA and surgical osteosynthesis with locked nails is a safe and effective treatment for pathological fractures or malignant impending fractures of long bone metastases of the humerus, femur and tibia. Further analyses with larger cohorts are warranted to confirm these findings.

Abstract Background Adolescent idiopathic scoliosis (AIS) is a common spinal deformity. Posterior spinal fusion remains an important surgical treatment for AIS. This study aims to determine the predictive factors for intraoperative blood loss in AIS surgery. Methods Patients who had undergone posterior spinal fusion for adolescent idiopathic scoliosis in a single university hospital were reviewed over a 7-year period. Predictive factors for intra-operative blood loss were studied by multivariate analysis to derive a regression model. Receiver operating characteristic analysis was performed to determine the cut-off values of factors contributing to significant intraoperative blood loss (≥500 ml). Results Two hundred and twelve patients were included. Intraoperative blood loss was found to be correlated with gender (rs = 0.30 (0.17–0.43)), preoperative hemoglobin level (rs = 0.20 (0.04–0.31)), preoperative Cobb angle (rs = 0.20 (0.02–0.29)), number of fused levels (rs = 0.46 (0.34–0.58)), operation duration (rs = 0.65 (0.54–0.75)), number of anchors (rs = 0.47 (0.35–0.59)), and p-value ranged from < 0.001 to < 0.05. Significant intraoperative blood loss was influenced by the male gender, operation duration greater than 257.5 min and more than 10 anchors used. Conclusions Male gender, increased operation duration and higher number of anchors predicted higher intra-operative blood loss.
