Abstract
BACKGROUND Although elective procedures have life-changing potential, all surgeries come with an inherent risk of reoperation. There is a gap in knowledge investigating the risk of reoperation across orthopaedics. We aimed to identify the elective orthopaedic procedures with the highest rate of unplanned reoperation and the reasons for these procedures having such high reoperation rates. METHODS Patients in the NSQIP database were identified using CPT and ICD-10 codes. We isolated 612,815 orthopaedics procedures from 2018 to 2020 and identified the 10 CPT codes with the greatest rate of unplanned return to the operating room. For each index procedure, we identified the ICD-10 codes for the reoperation procedure and categorized them into infection, mechanical failure, fracture, wound disruption, hematoma or seroma, nerve pathology, other, and unspecified. RESULTS Below knee amputation (BKA) (CPT 27880) had the highest reoperation rate of 6.92% (37 of 535 patients). Posterior-approach thoracic (5.86%) or cervical (4.14%) arthrodesis and cervical laminectomy (3.85%), revision total hip arthroplasty (5.23%), conversion to total hip arthroplasty (4.33%), and revision shoulder arthroplasty (4.22%) were among the remaining highest reoperation rates. The overall leading causes of reoperation were infection (30.1%), mechanical failure (21.1%), and hematoma or seroma (9.4%) for the 10 procedures with the highest reoperation rates. CONCLUSIONS This study successfully identified the elective orthopaedic procedures with the highest 30-day return to OR rates. These include BKA, posterior thoracic and cervical spinal arthrodesis, revision hip arthroplasty, revision total shoulder arthroplasty, and cervical laminectomy. With this data, we can identify areas across orthopaedics in which revising protocols may improve patient outcomes and limit the burden of reoperations on patients and the healthcare system. Future studies should focus on the long-term physical and financial impact that these reoperations may have on patients and hospital systems. LEVEL OF CLINICAL EVIDENCE IV.

Effect of an Airbag-selective Portal Vein Blood Arrester on the Liver after Hepatectomy: A New Technique for Selective Clamping of the Portal Vein. Curr Med Sci 2024; 44:380-390.

Abstract
OBJECTIVE A novel technique was explored using an airbag-selective portal vein blood arrester that circumvents the need for an intraoperative assessment of anatomical variations in patients with complex intrahepatic space-occupying lesions. METHODS Rabbits undergoing hepatectomy were randomly assigned to 4 groups: intermittent portal triad clamping (PTC), intermittent portal vein clamping (PVC), intermittent portal vein blocker with an airbag-selective portal vein blood arrester (APC), and without portal blood occlusion (control). Hepatic ischemia and reperfusion injury were assessed by measuring the 7-day survival rate, blood loss, liver function, hepatic pathology, hepatic inflammatory cytokine infiltration, hepatic malondialdehyde levels, and proliferating cell nuclear antigen levels. RESULTS Liver damage was substantially reduced in the APC and PVC groups. The APC animals exhibited transaminase levels similar to or less oxidative stress damage and inflammatory hepatocellular injury compared to those exhibited by the PVC animals. Bleeding was significantly higher in the control group than in the other groups. The APC group had less bleeding than the PVC group because of the avoidance of portal vein skeletonization during hepatectomy. Thus, more operative time was saved in the APC group than in the PVC group. Moreover, the total 7-day survival rate in the APC group was higher than that in the PTC group. CONCLUSION Airbag-selective portal vein blood arresters may help protect against hepatic ischemia and reperfusion injury in rabbits undergoing partial hepatectomy. This technique may also help prevent liver damage in patients requiring hepatectomy.

Abstract
Objectives The aims of the study were to compare the consumption of blood products before and after the implementation of a bleeding management algorithm in patients undergoing liver transplantation and to determine the feasibility of a multicentre, randomized study. Background Liver transplantation remains the only curative therapy for patients with end-stage liver disease, but it carries a high risk of surgical bleeding. Materials and Methods Retrospective study of patients treated before (group 1) and after (group 2) implementation of a haemostatic algorithm guided by viscoelastic testing, including use of lyophilized coagulation factor concentrates (prothrombin complex and fibrinogen concentrates). Primary outcome was the number of units of blood products transfused in 24 h after surgery. Secondary outcomes included hospital stay, mortality, and cost. Results Data from 30 consecutive patients was analysed; 14 in group 1 and 16 in group 2. Baseline data were similar between groups. Median total blood product consumption 24 h after surgery was 33 U (IQR: 11-57) in group 1 and 1.5 (0-23.5) in group 2 (p = 0.028). Significantly fewer units of red blood cells, fresh frozen plasma, and cryoprecipitate were transfused in group 2 versus group 1. There was no significant difference in complications, hospital stay, or in-hospital mortality between groups. The cost of haemostatic therapy was non-significantly lower in group 2 versus group 1 (7,400 vs. 15,500 USD; p = 0.454). Conclusion The haemostatic management algorithm was associated with a significant reduction in blood product use during 24 h after liver transplantation. This study demonstrated the feasibility and provided a sample size calculation for a larger, randomized study.

Abstract
ABSTRACT Background: The objective of this study was to investigate whether transrectal intracolon (TRIC) cooling can prolong the survival duration in a rat hemorrhagic shock (HS) model. Methods: A lethal HS was induced by bleeding 47% of the total blood volume. A TRIC device was placed into the colon to maintain the intracolon temperature either at 37°C (TRIC37) or at 10°C (TRIC10) post-HS. In the surface cooling (SC) rats, the body temperatures were maintained at the same level as the esophageal temperature of the TRIC10 rats. A separated group of TRIC10 rats were resuscitated (Res) at 90 min post-HS. A total of six groups were as follows: (i) Sham TRIC37 (n = 5), (ii) Sham TRIC10 (n = 5), (iii) HS TRIC37 (n = 5), (iv) HS TRIC10 (n = 6), (v) HS SC (n = 6), and (vi) HS TRIC10 + Res (n = 6). Results: An average post-HS survival time was 18.4 ± 9.4 min in HS TRIC37 and 82 ± 27.82 min in the HS SC group. In striking contrast, the HS TRIC10 group exhibited an average survival time of 150.2 ± 66.43 min. The post-HS blood potassium level rose significantly in the HS TRIC37 and HS SC, whereas it remained unchanged in the TRIC10 groups. Post-HS intestinal damage occurred in HS TRIC37 and HS SC groups but virtually absent in HS TRIC10 groups. After resuscitation at 90 min post-HS, all HS TRIC10 rats were fully recovered from the lethal HS. Conclusions: TRIC10 reversed the high blood potassium level, prevented the intestinal damage, and prolonged the survival duration by sixfold relative to normothermia and by twofold compared with SC post-HS. All TRIC10 rats were successfully resuscitated at 90 min post-HS.

Abstract
Background As the aging population increases, osteoporotic neck of femur fracture cases will continue to rise. Although hemiarthroplasty or half hip replacement is the treatment of choice in a majority of patients, a small but definite cohort of patients would need a total hip replacement. In these elderly patients who often have comorbidities, the use of cement to fix the prosthesis is often quoted as beneficial in view of perceived lower blood loss compared to uncemented fixation of the prosthesis. However, the cementation of the implant in itself has inherent problems. This study examined three modalities of fixation of a prosthesis for total hip replacement in the neck of femur fractures, namely, cemented, hybrid, and uncemented, and compared their relative intraoperative blood loss. Methodology This is a retrospective study with a follow-up of two years. Patients who presented to a level 1 trauma center in an inner city metropolitan with neck of femur fractures and were treated by total hip replacement were included in the study. Intraoperative blood loss was calculated using Nadler's formula. Results There was no statistical difference in intraoperative blood loss in either of the three groups of patients, namely, cemented, hybrid, or uncemented total hip replacement for neck of femur fractures. Conclusions Intraoperative blood loss should not influence the modality of prosthesis fixation for total hip replacement in neck of femur fractures.

Abstract
BACKGROUND A good control of intraoperative bleeding is key for adequate anatomical visualization during endoscopic sinus surgery (ESS). The objective of this review was to assess the practice of hot intranasal saline irrigation (HSI) in achieving intraoperative hemostasis and good surgical field quality during ESS. METHODS An electronic search was performed via PubMed, SCOPUS, Google Scholar, and Cochrane from inception to June 2022. The included trials were evaluated according to the recommendations of the Cochrane Handbook for Systematic Reviews. The primary outcome assessed was the intraoperative bleeding score of the surgical field. The mean arterial pressure, duration of the surgery, amount of blood loss and surgeon's satisfaction score were assessed as the secondary outcomes. The risk of bias for each study was evaluated using the Cochrane risk of bias tool. RESULTS A total of 254 records were identified after removal of duplicates. Based on the title and abstract 246 records were excluded, leaving seven full texts for further consideration. Five records were excluded following full text assessment. Three trials with a total of 212 patients were selected. Hot saline irrigation was superior to control in the intraoperative bleeding score (MD - 0.51, 95% CI - 0.84 to - 0.18; P < 0.001; I2 = 72%; very low quality of evidence) and surgeon's satisfaction score (RR 0.18, 95% CI 0.09 to 0.33; P < 0.001; I2 = 0%; low quality of evidence). The duration of surgery was lengthier in control when compared to HSI (MD - 9.02, 95% CI - 11.76 to - 6.28; P < 0.001; I2 = 0; very low quality of evidence). The volume of blood loss was greater in control than HSI (MD - 56.4, 95% CI - 57.30 to - 55.51; P < 0.001; I2 = 0%; low quality of evidence). No significant difference between the two groups for the mean arterial pressure was noted (MD - 0.60, 95% CI - 2.17 to 0.97; P = 0.45; I2 = 0%; low quality of evidence). CONCLUSIONS The practice of intranasal HSI during ESS is favorable in controlling intraoperative bleeding and improving the surgical field quality. It increases the surgeon's satisfaction, reduces blood loss, shortens operative time and has no effect on intraoperative hemodynamic instability.

Abstract
A direct anterior approach (DAA) is a technique practiced by arthroplasty surgeons that can be technically challenging, most notably for inexperienced surgeons. The lateral femoral circumflex artery (LFCA) is a branch of the femoral artery that crosses the surgical field during DAA and is an important landmark for superficial surgical dissection. If the vessel is not identified, significant bleeding may occur, and visualization may be impaired. This study aimed to develop a reliable method to identify and ligate the LFCA with minimal bleeding. First, a retrospective review was performed on a series of patients who underwent primary DAA total hip arthroplasty. Epidemiologic and intraoperative radiologic information was collected to determine the 2-dimensional location of the LFCA as it coursed through the surgical interval. Second, a series of computed tomography (CT) angiograms were compared to validate the intraoperative anatomic findings. In this study, 108 patients were evaluated fluoroscopically and 100 CT angiograms were obtained, for 208 total patients. The distance of the LFCA from the lesser trochanter with standard fluoroscopy (LT/TD) was 0.600 vs 0.438 on CT angiogram. Mean offset from midline (offset/femur diameter) was 0.166 lateral to midline vs 0.36 medial to midline. Median value of offset was 0 vs 0.411-representing a position on the anatomic axis of the femur. This study confirmed that the LFCA is found approximately one-third to two-thirds of the way between the lesser and greater trochanters along the anatomic axis of the femur for most patients. Surgeons who are new to DAA can use the LFCA as a reliable landmark to confirm the correct interval. [Orthopedics. 2022;45(5):262-268.].

Abstract
Trauma is the leading cause of death in young people with a considerable socio-economic impact worldwide. A trimodal distribution of trauma mortality was described in the past, but recently different studies underlined a progressive change in trauma mortality distribution linked to improvement in trauma care. This study aimed to analyze the mortality trends in a Level-One Trauma Center in Italy. Data on 6065 patients consecutively admitted to the Trauma Center between 2011 and 2020 were selected and retrospectively analyzed. Causes of Death (CODs) and time of death were stratified in four main groups and the patient sample was further divided into five age groups. Multivariate regression models were then performed to identify independent predictors of mortality. The most common COD in all age groups was Central Nervous System injuries. Immediate deaths (in ED) affected mostly patients over 75 years of age (34.3%). Deaths caused by massive hemorrhage occurred soon upon arrival in the ED, whereas deaths due to other causes (e.g. sepsis, MOF) after the first week. Patients' characteristics, the need for emergency procedures and high trauma severity scores were independent predictors of deaths. This study represented the first analysis on trauma mortality distribution in Italy over a nine-year period. The trimodal distribution described in the past seems to be no longer present in Italy, due to improvements in trauma systems and critical care. However, the high number of immediate and acute deaths underlies a persisting need for efforts in injury prevention and control .

Abstract
Minimally invasive endovascular embolization is a widely used clinical technique used for the occlusion of blood vessels to treat various diseases. Different occlusive agents ranging from gelatin foam to synthetic polymers such as poly(vinyl alcohol) (PVA) have been commercially used for embolization. However, these agents have some drawbacks, such as undesired toxicity and unintended and uncontrolled occlusion. To overcome these issues, several polymer-based embolic systems are under investigation including biocompatible and biodegradable microspheres, gelling liquid embolic with controlled occlusive features, and trackable microspheres with enhanced safety profiles. This review aims to summarize recent advances in current and emerging polymeric materials as embolization agents with varying material architectures. Furthermore, this review also explores the potential of combining injectable embolic agents and cell therapy to achieve more effective embolization with the promise of outstanding results in treating various devastating diseases. Finally, limitations and challenges in developing next-generation multifunctional embolic agents are discussed to promote advancement in this emerging field.

Abstract
BACKGROUND Viscoelastic tests (rotational thromboelastometry, ROTEM®), together with the implementation of a specific algorithm for coagulation management in cardiac surgery, enable perioperative coagulopathy to be better controlled. METHODS Retrospective cohort study including 675 patients who underwent cardiac surgery with cardiopulmonary bypass. The incidence of allogeneic blood transfusions and clinical postoperative complications were analyzed before and after ROTEM® implementation. RESULTS Following viscoelastic testing and the implementation of a specific algorithm for coagulation management, the incidence of any allogeneic blood transfusion decreased (41.4% vs 31.9%, p = .026) during the perioperative period. In the group monitored with ROTEM®, decreased incidence of transfusion was observed for packed red blood cells (31.3% vs 19.8%, p = .002), fresh frozen plasma (9.8% vs 3.8%, p = .008), prothrombin complex concentrate administration (0.9% vs 0.3%, p = .599) and activated recombinant factor VII (0.3% vs 0.0%, p = .603). Increased incidence was observed for platelet transfusion (4.8% vs 6.8%, p = .530) and fibrinogen concentrate (0.9% vs 3.5%, p = .066), tranexamic acid (0.0% vs 0.6%, p = .370) and protamine administration (0.6% vs 0.9%, p = .908). Similar results were observed in the postoperative period, but with a decreased incidence of platelet transfusion (4.8% vs 3.8%, p = .813). In addition, statistically significant reductions were detected in the incidence of postoperative bleeding (9.5% vs 5.3%, p = .037), surgical reexploration (6.0% vs 2.9%, p = .035), and length of Intensive Care Unit (ICU) stay (6.0 days vs 5.3 days, p = .026). CONCLUSIONS The monitoring of hemostasis by ROTEM® in cardiac surgery, was associated with decreased incidence of allogeneic blood transfusion, clinical hematologic postoperative complications and lengths of ICU stay.

Sabab A, Liu S, Javadiyan S, McAdam CJ, Hanton LR, Jukes A, Vreugde S, Wormald PJ. The effect of chemical and structural modifiers on the haemostatic process and cytotoxicity of the beta-chitin patch. Sci Rep 2021; 11:18577. [PMID: 34535704 PMCID: PMC8448852 DOI: 10.1038/s41598-021-97781-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2020] [Accepted: 08/30/2021] [Indexed: 12/03/2022] Open
Abstract
Beta-chitin patch has previously been proven to be an effective haemostat, but whether modifying the patch affects its efficacy and safety, remains unanswered. In this study, the patch was modified using polyethylene oxide, Pluronic-F127, calcium, increased thickness or polyphosphate, and their effect on the process of haemostasis and cytotoxicity was tested and compared with standard-of-care, Surgicel and FloSeal. Whole blood collected from volunteers was applied to the patches to test their whole blood clotting and thrombin generation capacities, whilst platelet isolates were used to test their platelet aggregation ability. The fluid absorption capacity of the patches was tested using simulated body fluid. Cytotoxicity of the patches was tested using AlamarBlue assays and PC12 cells and the results were compared with the standard-of-care. In this study, beta-chitin patch modifications failed to improve its whole blood clotting, platelet aggregation and thrombin generation capacity. Compared to non-modified patch, modifications with polyethylene oxide or calcium reduced platelet aggregation and thrombin generation capacity, while increasing the thickness or adding polyphosphate decreased platelet aggregation capacity. The cytotoxicity assays demonstrated that the beta-chitin patches were non-toxic to cells. In vivo research is required to evaluate the safety and efficacy of the beta-chitin patches in a clinical setting.

Effect of Intra- and Post-Operative Fluid and Blood Volume on Postoperative Pulmonary Edema in Patients with Intraoperative Massive Bleeding. J Clin Med 2021; 10:jcm10184224. [PMID: 34575335 PMCID: PMC8467689 DOI: 10.3390/jcm10184224] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2021] [Revised: 09/03/2021] [Accepted: 09/15/2021] [Indexed: 11/30/2022] Open
Abstract
In patients with intraoperative massive bleeding, the effects of fluid and blood volume on postoperative pulmonary edema are uncertain. Patients with intraoperative massive bleeding who had undergone a non-cardiac surgery in five hospitals were enrolled in this study. We evaluated the association of postoperative pulmonary edema risk and intra- and post-operatively administered fluid and blood volumes in patients with intraoperative massive bleeding. In total, 2090 patients were included in the postoperative pulmonary edema analysis, and 300 patients developed pulmonary edema within 72 h of the surgery. The postoperative pulmonary edema with hypoxemia analysis included 1660 patients, and the condition occurred in 161 patients. An increase in the amount of red blood cells transfused per hour after surgery increased the risk of pulmonary edema (hazard ratio: 1.03; 95% confidence interval: 1.01–1.05; p = 0.013) and the risk of pulmonary edema with hypoxemia (hazard ratio: 1.04; 95% confidence interval: 1.01–1.07; p = 0.024). An increase in the red blood cells transfused per hour after surgery increased the risk of developing pulmonary edema. This increase can be considered as a risk factor for pulmonary edema.

Abstract
The Haemostasis Traffic Light is a cognitive aid with a user-centred design to enhance and simplify situation awareness and decision-making during peri-operative bleeding. Its structure helps to prioritise therapeutic interventions according to the pathophysiology and the severity of the bleeding. This investigator-initiated, randomised, prospective, international, dual-centre study aimed to validate the Haemostasis Traffic Light by adapting it to the local coagulation protocols of two university hospitals. Between 9 January and 12 May 2020, we recruited 84 participants at the University Hospital Zurich, Switzerland, and the Italian Hospital of Buenos Aires, Argentina. Each centre included 21 resident and 21 staff anaesthetists. Participants were randomly allocated to either the text-based algorithm or the Haemostasis Traffic Light. All participants managed six bleeding scenarios using the same algorithm. In simulated bleeding scenarios, the design of the Haemostasis Traffic Light algorithm enabled more correctly solved cases, OR (95%CI) 7.23 (3.82-13.68), p < 0.001, and faster therapeutic decisions, HR (95%CI) 1.97 (1.18-3.29, p = 0.010). In addition, the tool improved therapeutic confidence, OR (95%CI) 4.31 (1.67-11.11, p = 0.003), and reduced perceived work-load coefficient (95%CI) -6.1 (-10.98 to -1.22), p = 0.020). This study provides empirical evidence for the importance of user-centred design in the development of haemostatic management protocols.

Abstract
The natural mechanisms of the body cannot control massive hemorrhaging, resulting in a requirement for hemostatic intervention. In this study, Graphene oxide and Chitosan aerogels reinforced with grape seed (SD) and skin (SK) extracts were developed for use as hemostatic agents by evaluating the influence of pH on their synthesis, and the amount of grape extract added on the physical and chemical properties of the aerogels. The material was evaluated by FTIR, XRD, Raman spectroscopy, DLS, uniaxial compression tests and SEM. The capacity of the aerogels to absorb water, PBS and blood, as well as their coagulation capacity, were determined. In addition, the release profile for grape extracts in PBS and the material's cytotoxicity were determined. The aerogels that were synthesized under basic conditions and loaded with grape extracts were more rigid and negatively charged, and they presented smaller pores than the un-loaded acidic aerogels. For all aerogels, the hemoglobin absorption was greater than 90 % in the first 30 s. A higher density of adsorbed blood cells was observed on aerogels loaded with a higher amount of grape extract. The maximum release of extract from the aerogels occurred for those loaded with SK extracts at a basic pH; the aerogels that were prepared under acidic conditions dissolved in the media. Aerogels loaded with SK extracts under alkaline conditions were not cytotoxic toward human dermal fibroblasts and exhibited cell viabilities above 90 %. These findings suggest that these aerogels have the potential for use as hemostatic agents in wound management.

Abstract
Background During pediatric epilepsy surgery, due to low circulating blood volume, intraoperative bleeding can result in significant hemodynamic instability, thereby requiring meticulous hemodynamic and transfusion strategies. Knowing the source of bleeding during the procedure would allow medical staff to better prepare the perioperative protocols for these patients. We compared intraoperative bleeding between the first (involving skin to meninges) and second (involving brain parenchyma) stages of epilepsy surgery to investigate the differences between various anatomical sites. Methods We reviewed the electronic medical records of 102 pediatric patients < 14 years old who underwent two-stage epilepsy surgeries during January 2012–December 2016. Invasive subdural grids were placed via craniotomy during Stage 1 and the epileptogenic zone was removed during Stage 2 of the surgery. We compared the volume of intraoperative bleeding between these two surgeries and identified variables associated with bleeding using multivariate regression analysis. Results Both surgeries resulted in similar intraoperative bleeding (24 vs. 26 ml/kg, P = 0.835), but Stage 2 required greater volumes of blood transfusion than Stage 1 (18.4 vs. 14.8 ml/kg, P = 0.011). Massive bleeding was associated with patients < 7 years of age in Stage 1 and weighing < 18 kg in Stage 2. Conclusions The volume of intraoperative bleeding was similar between the two stages of pediatric epilepsy surgery and was large enough to require blood transfusions. Thus, blood loss during pediatric epilepsy surgery occurred at both anatomic sites. This indicates the necessity of early preparation for blood transfusion in both stages of pediatric epilepsy surgery.

Abstract
Background Emergency reoperation is considered to be a quality indicator in surgery. We analyzed the risk factors for emergency reoperations. Methods Patients who underwent emergency operations from January 1, 2017, to December 31, 2017, at our hospital were reviewed in this retrospective study. Multivariate logistic regression was performed for the perioperative risk factors for emergency reoperation. Results A total of 1,481 patients underwent emergency operations during the study period. Among them, 79 patients received emergency reoperations. The variables related to emergency reoperation included surgeries involving intracranial and intraoral lesions, highest mean arterial pressure ≥ 110 mmHg, highest heart rate ≥ 100 beats/min, anemia, duration of operation >120 min, and arrival from the intensive care unit (ICU). Conclusions The type of surgery, hemodynamics, hemoglobin values, the duration of surgery, and arrival from ICU were associated with emergency reoperations.

Abstract
PURPOSE Few comparative studies are available on the long-term prognostic role of mesopancreas (MP) excision after pancreaticoduodenectomy (PD). We compared the long-term outcomes of patients undergoing standard PD (sPD) and PD with MP excision (PD-MPe). METHODS Sixty sPDs were compared to 60 matched PD-MPe patients for intraoperative and postoperative data, histopathological findings, and long-term outcomes. RESULTS R0 rate was similar in the two groups (p = 0.17). However, PD-MPe related to a lower rate of MP resection margin positivity (16.7% vs 5%; p = 0.04) and to a higher harvested lymph nodes number (19.8 ± 7.6 vs 10.1 ± 5.1; p < 0.0001). Local tumor recurrence was more frequent in the sPD cohort (55.5% vs 26.8% in the PD-MPe group; p = 0.002), with a consequent worse disease-free survival (DFS) (14.8% vs 22.3%; p = 0.04). An inferior 5-year overall survival (OS) was noted in case of MP margin positivity compared with MP margin negativity (0% vs 29%; p < 0.0001). MP positivity resulted as an independent prognostic factor for both a worse OS and DFS at the multivariate analysis. CONCLUSION PD-MPe offers clinical advantages in terms of MP resection margin status, local recurrence, long-term mortality, and DFS. The lower MP positivity rate, achieved with PD-MPe, leads to better outcomes both in terms of OS and DFS.

Abstract
Minimally invasive transcatheter embolization is a common nonsurgical procedure in interventional radiology used for the deliberate occlusion of blood vessels for the treatment of diseased or injured vasculature. A wide variety of embolic agents including metallic coils, calibrated microspheres, and liquids are available for clinical practice. Additionally, advances in biomaterials, such as shape-memory foams, biodegradable polymers, and in situ gelling solutions have led to the development of novel preclinical embolic agents. The aim here is to provide a comprehensive overview of current and emerging technologies in endovascular embolization with respect to devices, materials, mechanisms, and design guidelines. Limitations and challenges in embolic materials are also discussed to promote advancement in the field.

Abstract
PURPOSE The amount of intraoperative hemorrhages and factors associated with hemorrhages and transfusions during revision total hip arthroplasty (reTHA) have not been identified for Japanese patients. We aimed to clarify the amount of intraoperative hemorrhages, and to elucidate the factors associated with hemorrhages and transfusions during reTHA in Japanese patients. METHODS We retrospectively reviewed patients who underwent reTHA (n = 48) and primary total hip arthroplasty (pTHA) (n = 615) in a single hospital and extracted data regarding hemorrhage, transfusion, patient comorbidities, and surgical anesthesia. We defined massive blood loss (MBL) as a hemorrhage comprising more than half of the circulating blood volume within 3 h. The odds ratio (OR) and 95% confidence interval (CI) were estimated using a multivariate logistic regression analysis. RESULTS There was a significant difference in hemorrhages between reTHA and pTHA patients (1790 g versus 625 g; p < 0.001). Among patients with reTHA, MBL was significantly associated with younger age (OR 0.91; 95% CI 0.84-1.00; p = 0.04) and lower body mass index (BMI) (OR 0.69; 95% CI 0.53-0.91; p = 0.01). Although not significant, the incidence of MBL tended to be higher for patients with hyperlipidemia (OR 4.88; 95% CI 0.99-24.1; p = 0.051). Furthermore, the need for allogeneic transfusion was significantly associated with the number of prepared autologous blood packs (OR 0.15; 95% CI 0.07-0.55; p = 0.002). CONCLUSION Although this study was limited by its small population and a possibility of underestimating the hemorrhage, hemorrhages in reTHA patients was two times greater than that in pTHA patients. Younger age and lower BMI increased the risk of MBL in reTHA. Preparing autologous blood decreased the risk of intraoperative allogeneic transfusion.

Abstract
Background: Intraoperative hemorrhage is one of the problems during surgery and, if it happens in a high volume without an immediate action to control, it can be fatal. Nowadays, various injectable solutions are used. The aim of this study was to compare the acid–base and hemodynamic status of the patient using two solutions, Ringer lactate and 1.3% sodium bicarbonate, in half saline solution. Materials and Methods: This clinical trial was performed at the Al-Zahra Hospital in 2013 on 66 patients who were randomly selected and put in two studied groups at the onset of hemorrhage. For the first group, crystalloid Ringer lactate solution and for the second group, 1.3% sodium bicarbonate in half-normal saline solution was used. Electrocardiogram, heart rate, O2 saturation non-invasive blood pressure and end-tidal CO2 were monitored. The arterial blood gas, blood electrolytes, glucose and blood urea nitrogen were measured before serum and blood injection. After the infusion of solutions and before blood transfusions, another sample was sent for measurement of blood parameters. Data were analyzed using SPSS software. Results: The mean arterial pressure was significantly higher in the second group than in the first group at some times after the infusion of solutions. pHh levels, base excess, bicarbonate, sodium, strong ion differences and osmolarity were significantly greater and potassium and chloride were significantly lower in the second group than in the first group after the infusion of solutions. Conclusion: 1.3% sodium bicarbonate in half-normal saline solution can lead to a proper correction of hemodynamic instability. By maintaining hemodynamic status, osmolarity and electrolytes as well as better balance of acid–base, 1.3% sodium bicarbonate solution in half-normal saline solution can be more effective than Ringer lactate solution during intraoperative bleeding.

Abstract
Surgical management of renal cell carcinoma extending into the inferior vena cava (IVC) is almost always accompanied by massive intraoperative blood loss and associated complications. It is a widely recognised problem, and its active management is essential in improving the perioperative morbidity and mortality. We share our experience with a similar case of open radical nephrectomy with massive blood loss of twice the circulating volume in a duration of <8 surgical hours. Although we emphasise the goals of securing haemostasis, restoration of circulating volume, and efficient management by replacing blood components, in the present case, despite the above-mentioned goals being fulfilled, we were unable to extricate the patient from haemorrhagic shock by conventional means and therefore resorted to desperate measures, namely the novel approach of infrarenal aortic clamping along with higher than recommended vasopressor support. We resorted to this in order to maintain the haemodynamic parameters and to prevent avoidable morbidity and mortality related to persistent intraoperative hypotension. With such an approach, we successfully managed the patient perioperatively, ultimately resulting in the patient being discharged after a week of intensive care unit stay without major complications.
