This paper aimed to evaluate the effect of preoperative transarterial embolization (TAE) on estimated blood loss (EBL) during surgical excision of the vertebral tumors. Three hundred and forty-eight patients with spinal tumors were retrospectively analyzed. The preoperative TAE group consisted of 190 patients and the control group consisted of 158 patients. Gelatin sponge particles mixed withy contrast agent were used in the TAE group to embolize the tumor-feeding artery. The factors evaluated included: the time interval between embolism and surgery; the number of vertebrae involved by the tumor; pathological type of tumor; surgical approach; extent of excision and instrumental fixation. The time interval (P = 0.4669)between embolism and surgery had no significant correlation with EBL during surgery. The pathological diagnosis of vertebral tumor such as plasma cell myeloma, giant cell tumor, chondrosarcoma, hemangioma and metastasis had no significant correlation with EBL between the TAE group and control group during surgery, while the EBL of chordoma in the TAE group was significantly higher than that in the control group (p = 0.0254). The number of vertebrae involved (p = 0.4669, 0.6804, 0.6677), posterior approach (p = 0.3015), anterior approach (p = 0.2446), partial excision (p = 0.1911) and instrumental fixation (p = 0.1789) had no significant correlation with EBL during surgery between the TAE group and the control group. This study showed that preoperative TAE of the spinal tumor had no significant effect on intra-operative blood loss during surgical excision of the spinal tumor. In view of the risk of embolism, this method should be carefully considered.

AbstractTranexamic acid (TXA) reduces surgical blood loss and alleviates inflammatory response in total hip arthroplasty. However, studies have not identified an optimal regimen. The objective of this study was to identify the most effective regimen of multiple-dose oral TXA in achieving maximum reduction of blood loss and inflammatory response based on pharmacokinetic recommendations. We prospectively studied four multiple-dose regimens (60 patients each) with control group (group A: matching placebo). The four multiple-dose regimens included: 2-g oral TXA 2 hours pre-operatively followed by 1-g oral TXA 3 hours post-operatively (group B), 2-g oral TXA followed by 1-g oral TXA 3 and 7 hours post-operatively (group C), 2-g oral TXA followed by 1-g oral TXA 3, 7 and 11 hours post-operatively (group D) and 2-g oral TXA followed by 1-g oral TXA 3, 7, 11 and 15 hours post-operatively (group E). The primary endpoint was estimated blood loss on post-operative day (POD) 3. Secondary endpoints were thromboelastographic parameters, inflammatory components, function recovery and adverse events. Groups D and E had significantly less blood loss on POD 3, with no significant difference between the two groups. Group E had the most prolonged haemostatic effect, and all thromboelastographic parameters remained within normal ranges. Group E had the lowest levels of inflammatory cytokines and the greatest range of motion. No thromboembolic complications were observed. The post-operative four-dose regimen brings about maximum efficacy in reducing blood loss, alleviating inflammatory response and improving analgaesia and immediate recovery.

Background: Postpartum hemorrhage is a common and occasionally life-threatening complication of labor. Cesarean section is associated with more blood loss in compared to vaginal delivery. Despite, there is a trend for increasing cesarean section rates in both developed and developing countries thereby increasing the risk of morbidity and mortality, especially among anemic women. The objective of this study was to evaluate the effect of preoperative administration of intravenous Tranexamic acid on blood loss during and after elective cesarean section.Methods: This was a prospective, randomized controlled study with 160 eligible pregnant women of 37 or more period of gestation. They were all planned for elective cesarean section and were randomized into two groups either to receive 10ml (1gm) of Tranexamic acid intravenously or 10ml of normal saline. Blood loss was measured during and for 24 hours after operation.Results: The mean estimated blood loss was significantly lower in women treated with Tranexamic acid compared with women in the placebo group (392.13 ml±10.06 vs 498.69 ml±15.87, respectively; p<0.001). The mean difference in pre-operative and post-operative hemoglobin levels was statistically significant in the Tranexamic acid group than in the control group (0.31±0.18 vs 0.79±0.23, respectively; p<0.001).Conclusions: Pre-operative use of Tranexamic acid is associated with reduced blood loss during and after elective cesarean section. In a developing country like ours where postpartum hemorrhage is a major threat to the life of the mothers, it seems to be a promising option.

Abstract Purpose To evaluate the efficacy and safety of prophylactic balloon occlusion of the infrarenal abdominal aorta among women with pernicious placenta previa and placenta accreta.Methods This retrospective study included 110 patients with pernicious placenta previa and placenta accreta. The control group consisted of 55 patients who underwent cesarean section alone, and the study group included 55 patients who underwent precesarean prophylactic balloon occlusion of the infrarenal abdominal aorta. In addition, both of the groups were further divided according to FIGO clinical grading standards. Prevention of hysterectomy was the primary outcome evaluated. The secondary outcomes included operative duration, estimated blood loss, blood transfusion, intensive care unit admission, total hospital stay (days), and puerperal morbidity, and these data were compared between the two groups. Additionally, the neonatal outcomes were compared.Results There were no significant differences in maternal and neonatal outcomes in the PAS 2 and PAS 3 groups (P > 0.05). However, in the PAS 4 and PAS 5 groups, the amount of bleeding in the study group was significantly less than that in the control group (3533.3 ± 2391.4 vs 4293.6 ± 1235.4, P < 0.05), and the total hysterectomy rate was also lower (7.8% vs 13.2%, P < 0.05).Conclusion Precesarean infrarenal abdominal aortic balloon occlusion is an effective and safe option for treating pernicious placenta previa and placenta accreta and can effectively reduce the risk of hysterectomy and intraoperative blood loss in women with PAS grade 4-5.

Abstract Objective: This study aimed to evaluate the clinical efficacy of internal iliac artery(IIA) balloon occlusion in patients with pernicious placenta previa coexisting with placenta accreta. Background: Pernicious placenta previa is frequently reported to be complicated with placenta accreta, which contributes to serious consequences such as severe obstetric postpartum hemorrhage or even maternal mortality. Methods: Fifty-eight pernicious placenta previa patients complicated with placenta accreta were retrospectively reviewed. The ballon group consisted of 23 patients, who underwent a caesarean delivery with internal iliac artery occlusion. 35 patients were in the control group, who had a standard caesarean delivery. The primary outcomes were estimated blood loss (EBL), cesarean hysterectomy, and blood transferring volume. The secondary outcomes were operating time, intraoperative hemostatic approaches, surgical complications, balloon catheter–related complications, length of maternal stay, cost of hospitalization, and neonatal outcomes.Results: No difference was observed in estimated blood loss (EBL), blood transferring percentages and volume, additional measures to secure hemostasis , surgical complications, hospital stay postoperatively and newborn outcomes. More than 40% of the balloon group underwent hysterectomy because of uncontrollable postpartum bleeding (10[43.48%] vs. 11[31.43%],P=0.350).Complications related to occlusion of IIA did not occur.The duration of the surgery of the balloon group was significantly longer than that of the control group(123.52 min±74.76 versus 89.17±48.68,P=0.038), and the total hospitalization cost was also significantly higher than that of the control group(45116.67±9358.67 yuan versus 30615.41±11587.44yuan,P=0.000).Conclusion: IIA balloon occlusion in patients with pernicious placenta previa coexisting with placenta accreta did not reduce the hysterectomy rate during cesarean section, nor did it reduce blood loss and blood transfusion, but it prolonged the duration of the surgery and increased the total cost.

AbstractTranexamic acid (TXA) can reduce blood loss and decrease transfusion rates after total knee arthroplasty (TKA). The purpose of our study was to evaluate the efficacy of TXA in a homogenous, consecutive cohort of patients undergoing simultaneous bilateral primary TKA. This was a retrospective study of 50 consecutive patients who underwent bilateral simultaneous primary TKA between 2011 and 2015. Of these, 20 patients received TXA and 30 patients did not receive TXA and served as the control group. Primary outcome measurements were intraoperative estimated blood loss, hemoglobin (Hb) and Hematocrit (Hct) levels on postoperative day (POD) 1 and POD2, and blood transfusion rates. Secondary outcomes included length of stay (LOS), knee flexion/extension range of motion (ROM), and postoperative complications. There was no difference between groups for preoperative Hb and Hct (all p > 0.05). The TXA group demonstrate higher Hb levels at POD1 (11.7 in TXA vs. 10.4 controls; p < 0.001) and POD2 (10.5 in TXA vs. 9.6 controls; p < 0.001), as well as higher Hct levels at POD1 (35.6 in TXA vs. 32.1 controls; p < 0.001) and POD2 (31.9 in TXA vs. 29.3 controls; p < 0.001). There was less percentage variation in Hb levels in the TXA group from preoperative to POD1 (17.7% in TXA vs. 25.7% controls; p < 0.0001) and POD2 (26.1% TXA vs. 31.8% controls; p = 0.019). Similarly, less percentage variation in Hct levels in the TXA group from presurgery to POD1 (17.0% TXA vs. 25.7% controls; p < 0.0001) and POD2 (25.0% TXA vs. 31.3% controls; p = 0.005). A total of 23.3% of patients in the control group required transfusions compared with no patients in the TXA (p = 0.044). There were no differences in LOS, knee ROM, or number of complications. No thromboembolic events occurred. TXA in bilateral simultaneous TKA effectively reduces blood loss, maintains postoperative Hb and Hct levels, and significantly decreases blood transfusion rates. The level of evidence is level III (therapeutic study).

Abstract OBJECTIVE To determine the safety and efficacy of preoperative embolization of central nervous system (CNS) tumors with n-butyl cyanoacrylate (NBCA) liquid adhesive. METHODS Over a 6-yr period, 35 consecutive patients (12 women, 23 men; mean age, 42 yr; range, 6 mo to 75 yr) with a CNS tumor underwent preoperative embolization with NBCA. Tumor type, location, endovascular and surgical treatment, percent of tumor embolization, estimated blood loss, and neurological deficits related to embolization were evaluated retrospectively. RESULTS One hundred feeding arteries were embolized (mean, 3 vessels/patient). In only one case (3%) a normal artery was inadvertently occluded by the embolization. During follow-up the resulting neurological deficit resolved completely. There were no neurological deficits or inadvertent embolization events in the remaining 34 cases. The mean percent of tumor embolized was 68%, but did not significantly correlate with operative blood loss (Pearson's correlation coefficient, r = 0.049). CONCLUSION In experienced hands, CNS tumors can be embolized with NBCA liquid adhesive with a high degree of safety and efficacy. We believe that adroit embolization technique with NBCA and other embolisates should be part of the contemporary neuroendovascular armamentarium.

Intradural Extramedullary Tumour

Synovial sarcoma (SS) accounts for 5- 10% of all adult soft-tissue sarcomas and only 5% arises in the spine. It presents like any other spinal tumor, namely axial pain with symptoms due to neural compression. Imaging findings can also be similar to any other benign spinal tumor. We present a 43-year-old male who presented with symptoms of radiculopathy and neural compression and imaging revealed a dumbbell tumor at C6 to D1 with transforaminal and paraspinal extension on the right side. After surgical excision the histopathology revealed a rare synovial sarcoma of the spine. Synovial sarcoma of the spine though rare, are difficult to differentiate based on their presentation and imaging characteristics from benign spinal tumors. However, subtle findings on imaging and a pre-operative biopsy may aid in performing a more definitive surgery upfront rather than a re-do surgery after the histopathological diagnosis.

OBJECTIVEThe CO2 laser has been used on an intermittent basis in the microsurgical resection of brain tumors for decades. These lasers were typically cumbersome to use due to the need for a large, bulky design since infrared light cannot be transmitted via fiber-optic cables. Development of the OmniGuide cable, which is hollow and lined with an omnidirectional dielectric mirror, has facilitated the reintroduction of the CO2 laser in surgical use in a number of fields. This device allows for handheld use of the CO2 laser in a much more ergonomically favorable configuration, holding promise for microneurosurgical applications. This device was introduced into the authors’ practice for use in the microsurgical resection of skull base tumors, including vestibular schwannomas.METHODSThe authors reviewed the initial 41 vestibular schwannomas that were treated using the OmniGuide CO2 laser during an 8-month period from March 2010 to October 2010. The laser was used for all large tumors, and select medium-sized tumors were treated via both the translabyrinthine and retrosigmoid approaches. The estimated time of tumor resection and estimated blood loss were obtained from operating room records. Data regarding complications, facial nerve and hearing outcomes, and further treatment were collected from hospital and clinic records, MRI reports, and direct review of MR images. Time of resection and blood loss were compared to a control group (n = 18) who underwent surgery just prior to use of the laser.RESULTSA total of 41 patients with vestibular schwannomas were surgically treated. The median estimated time of tumor resection was 150 minutes, and the median estimated blood loss was 300 ml. The only operative complication was 1 CSF leak. Thirty-eight patients had normal facial nerve function at late follow-up. The median MRI follow-up was 52 months, and, during that time, only 1 patient required further treatment for regrowth of a residual tumor.CONCLUSIONSThe OmniGuide CO2 laser is a useful adjunct in the resection of large vestibular schwannomas. This device was used primarily as a cutting tool rather than for tumor vaporization, and it was found to be of most use for very large and/or firm tumors. There were no laser-associated complications, and the results compared favorably to earlier reports of vestibular schwannoma resection.

BackgroundThe goal of preoperative embolization of spinal tumors is to improve surgical outcomes by diminishing the vascular supply to the tumor to reduce intraoperative blood loss and operative time.ObjectiveTo report our institutional experience with spinal tumor embolization and review the present literature.MethodsClinical records from January 1, 2001 to December 31, 2012 were reviewed and analyzed. Angiograms were used to calculate the percentage reduction in tumor vascularity, and relevant clinical and operative data were collected and analyzed.ResultsThirty-seven patients underwent preoperative spinal tumor embolization (24 metastatic and 13 primary lesions) and were included in the study. One complication resulted in transient lower extremity weakness and was attributed to post-embolization swelling, which fully resolved after surgical resection. The transient neurological complication rate was 1/37 (3%) and the permanent rate was 0/37 (0%). The average surgical estimated blood loss (EBL) was 1946 mL (100–7000 mL) and the average operative time was 330 min (range 164–841 min). After embolization, tumor blush was reduced by 83% on average. Average pre- and postoperative modified Rankin Scale scores were 2.10 and 1.36, respectively (p=0.03). Cases in which tumor blush was decreased by ≥90% (classes 1 or 2) after embolization had significantly less operative blood loss than those cases in which <90% (classes 3 or 4) was achieved (mean EBL 1391 vs 2296 mL, respectively, p=0.05).ConclusionsSpinal tumor embolization is a safe procedure, is associated with few complications, and may improve surgical outcomes by limiting intraoperative blood loss and reducing operative time.

Objectives: The purpose of this article is to investigate the estimated blood loss in pregnant women undergoing cesarean section and placental extirpation to treat abnormal placentation and compare the outcomes of those who underwent prophylactic transcatheter arterial embolization (TAE) with those who did not. Methods: A retrospective study was conducted on 17 pregnant women diagnosed with abnormal placentation in 2001–2018 in a single tertiary center. The patients were diagnosed by surgical finding, ultrasound, or magnetic resonance imaging (MRI). These patients were divided into two groups: a prophylactic TAE group (11 patients) and a control group (6 patients). In the former group, prophylactic TAE of the bilateral uterine artery (UA) and/or internal iliac artery (IIA) was performed immediately after delivery of the infant. The placenta was removed in both groups. The primary outcomes were estimated blood loss (EBL), units of packed red blood cell (pRBC) transfusion, operative time, whether hysterectomy was performed, whether the patient was transferred to the intensive care unit (ICU), and hospitalization days. The secondary outcome was maternal complications. Results: Patients who received prophylactic TAE had significantly reduced intraoperative blood loss (990.9 ± 701.7 mL vs. 3448.3 ± 1767.4 mL, p = 0.018). Units of pRBC transfusion, operative time, hysterectomy, transfer to the ICU, and postoperative hospitalization days were not significantly different between the two groups. Thirteen patients (9 in the TAE group and 4 in the control group) received a blood transfusion during the operation. Three patients underwent a hysterectomy (1 in the TAE group and 2 in the control group). Five patients were transferred to the ICU (3 in the TAE group and 2 in the control group) for maternal complications or monitoring. In the prophylactic TAE group, 3 patients (27%) had a subsequent pregnancy within the next 5 years. Conclusions: Prophylactic TAE was safe and effective for reducing intraoperative hemorrhage from removing an invasive placenta in patients with abnormal placentation.
