Pre-operative synovial hyperaemia in haemophilia patients undergoing total knee replacement and the effects of genicular artery embolization: A retrospective cohort study. Haemophilia 2023; 29:1351-1358. [PMID: 37548064 DOI: 10.1111/hae.14835] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Revised: 06/29/2023] [Accepted: 07/26/2023] [Indexed: 08/08/2023]
Abstract
AIM Haemophilia is characterized by recurrent joint bleeding caused by a lack of clotting factor VIII or IX. Due to repeated joint bleeding, end-stage arthropathy occurs in relatively young patients. A total knee replacement (TKR) can be a solution. However, TKR may be complicated by perioperative and postoperative bleeds despite clotting factor therapy. The aim of this study was to evaluate the prevalence of pre-operative synovial hyperaemia and the effects of Genicular Artery Embolization on synovial hyperaemia and 3-month postoperative joint bleeding. METHODS In this retrospective cohort study, all patients with haemophilia who underwent periarticular catheter angiography between 2009 and 2020 were evaluated after written informed consent. Synovial hyperaemia on angiography was scored by an interventional radiologist. RESULTS Thirty-three angiography procedures in 24 patients were evaluated. Median age was 54.4 years (IQR 48.4-65.9). Preoperative synovial hyperaemia was observed in 21/33 joints (64%). Moderate and severe synovial hyperaemia was observed in 10/33 joints (30%). Synovial hyperaemia decreased in 13/15 (87%) joints after embolization. Three-month postoperative joint bleeding occurred in 5/32 joints: in 2/18 joints (11%) without synovial hyperaemia and in 3/14 joints (21%) with mild synovial hypertrophy. Non-embolized and embolized joints did not differ regarding 3-month postoperative bleeding (P = .425). No complications were observed after embolization. CONCLUSION One-third of patients with haemophilia requiring a TKR had moderate or severe synovial hyperaemia which can be reduced safely by Genicular Artery Embolization prior to TKR. Three-month postoperative bleeding appears to occur independently of the presence of residual mild synovial hyperaemia.

Abstract
The goal of this study was to describe hematologic and coagulation laboratory parameters and identify if these laboratory studies could predict blood loss in a cohort of pediatric patients undergoing complex cranial vault reconstruction (CCVR) for repair of craniosynostosis. We reviewed records from 95 pediatric CCVR patients between 2015 and 2019. Primary outcome measures were hematologic and coagulation laboratory parameters. Secondary outcome measures were intraoperative and postoperative calculated blood loss (CBL). Preoperative laboratory values were within normal limits and did not predict outcomes. Intraoperative platelet count and fibrinogen predicted CBL but without clinically relevant thrombocytopenia or hypofibrinogenemia. Intraoperative prothrombin time (PT) and partial thromboplastin time (PTT) predicted perioperative CBL, possibly reflecting surgically induced coagulopathy. Postoperative laboratory values did not predict postoperative blood loss. We found that standard hematologic and coagulation laboratory parameters predicted intraoperative and postoperative blood loss but provided limited mechanistic information to improve our understanding of coagulopathy in craniofacial surgery.

Abstract
STUDY DESIGN Prospective study OBJECTIVES: The occurrence of adverse events (AEs) during surgery is a major cause of increased economic costs, disability, or even death. This study aimed to prospectively identify and quantify AEs in patients undergoing spinal surgery at a neurosurgical tertiary care hospital. METHODS Patients who underwent spinal surgery and were discharged between January 2019 and December 2022 were enrolled prospectively. Each patient underwent a peer-reviewed AE evaluation at discharge. An AE was defined as any event that occurred up to 30 days postoperatively and resulted in an undesirable outcome. Patients were allocated to four groups according to spinal pathology (degenerative, oncologic, traumatic, and infectious). RESULTS During the study period, 1778 patients with a mean age of 55.4 ± 10.5 years underwent surgery. Elective surgery was performed in 90.8% (1615/1778) of patients, while emergency surgery was performed in 9.2% (163/1778). The overall rate of surgery-related AEs was relatively low (8.7%). Degenerative pathologies were the most frequent reasons for surgery (78.5%, 1396/1778). Wound infection was the most prevalent AE in patients with degenerative diseases (1.4%), of which 1.1% required revision surgery. Wound infection, dural leakage, and new neurological deficits had the same prevalence (2.1%) in patients with spinal tumors. Among patients with spinal trauma, two presented with postoperative epidural bleeding and underwent emergency surgery. Postoperative wound infection was the most prevalent AE in this group (9.5%), with 7.0% of affected patients requiring revision surgery. The overall rate of non-surgery-related AEs was 4.3%, and the overall mortality rate was low (0.4%). CONCLUSION AEs in spinal surgery remained low, with a prevalence of 8.7%. Documentation of AEs as part of clinical routine may be a key tool for identifying the occurrence of surgery-related and non-surgery-related AEs.

Abstract
OBJECTIVE After Endoscopic Sinus Surgery (ESS), packing plays an important role in wound healing and hemostasis. However, the effect of the packing removal procedure on physician stress has not been evaluated. The purpose of this study was to evaluate physician stress during packing removal for patients treated with AQUACEL® Ag Advantage versus KALTOSTAT®. METHODS This retrospective study included 15 patients who underwent packing with ESS for chronic rhinosinusitis performed at two centers; 9 were treated with AQUACEL® Ag Advantage and 6 were treated with KALTOSTAT®. Physician stress during packing removal was evaluated with the National Aeronautics and Space Administration-Task Load Index (NASA-TLX). The time required to remove the packing and the number of instruments used in the procedure were recorded. Postoperative bleeding (Boezaart bleeding score) and wound healing were graded. Patient symptoms on the day after surgery and pain during packing removal were assessed using a visual analog scale. RESULTS Computed tomography scores, asthma complications, and blood eosinophil counts were significantly higher in the AQUACEL® Ag Advantage group. Patient symptoms on the day after surgery were not significantly different between the two groups. Physician stress during the task of packing removal was significantly lower in the AQUACEL® Ag Advantage group than in the KALTOSTAT® group (35.5 vs. 81.0, p=0.016) according to the NASA-TLX scores. The number of instruments used in the procedure was significantly lower in the AQUACEL® Ag Advantage group than in the KALTOSTAT® group (3.0 vs. 6.0, p=0.015). There were no significant differences in procedure time for packing removal, postoperative bleeding, wound healing, or patient pain at the time of packing removal between the groups. CONCLUSION Physicians feel stressed about packing removal. In addition, AQUACEL® Ag Advantage is useful for packing after ESS, requiring fewer instruments for the procedure than KALTOSTAT® and reducing physician stress about the procedure. LEVEL OF EVIDENCE Level 3.

Abstract
BACKGROUND AL amyloidosis is associated with acquired factor X (FX) deficiency. Experience related to its management is limited to case reports and series using prothrombin complex concentrate, fresh frozen plasma, plasma exchange, recombinant activated factor seven, and desmopressin with limited and variable efficacy. FX concentrate has not been widely used in its management. STUDY DESIGN AND METHODS We report our experience with the perioperative use of FX concentrate (Coagadex) in two patients with AL amyloidosis-associated acquired FX deficiency requiring surgery, using their individual pharmacokinetic studies to manage perioperative hemostasis. Pharmacokinetic studies involved obtaining post-infusion FX activity at 10 min, 2, and 4 h following the administration of FX concentrate to calculate the FX half-life. RESULTS Both patients' plasma FX activity was successfully increased to provide perioperative hemostatic support. Monitoring FX activity post-surgery was also utilized to maintain FX activity levels to prevent post-operative bleeding. CONCLUSION Pharmacokinetic studies have a useful role in tailoring preoperative FX repletion in patients with AL amyloidosis associated with acquired FX deficiency.

Abstract
In patients with pulmonary embolism (PE) in the setting of trauma, administration of fibrinolytic therapy is contraindicated due to high risk of hemorrhage. Several studies have demonstrated the safety and efficacy of mechanical thrombectomy among all-comers with PE as an alternative to catheter-directed thrombolytics. However, the risks and benefits of mechanical thrombectomy treatment for pulmonary embolism in a trauma population are not well established. A retrospective analysis was performed in all patients who presented to Level 1 Trauma Center with acute trauma who were found to have a pulmonary embolism (PE) treated with mechanical thrombectomy. From May 2019 to December 2020, six patients were identified. Average age was 54 years, and four patients were male. Four patients had a saddle PE on computed tomography. All patients had an intermediate-high risk PE with troponin I elevation >0.04 ng/mL (average 0.42 ng/mL). Pulmonary Embolism Severity Index (PESI) score in all six patients was class III or IV. In all patients, the mechanical thrombectomy was performed with mean-PA pressure changing from average 40.33 to 31.5 mmHg. Average Intensive Care Unit (ICU) length of stay post-procedure was five days with two patients not requiring ICU stay. No patient had post-operative bleeding during their index stay. Average hemoglobin drop after mechanical thrombectomy was 1.33 g/dL. One patient died <30 days post-procedure due to septic shock and another >90 days later (5 months) from cardiac arrest from recurrent PE. The other four patients were still living >90 days post-procedure. No immediate or delayed postoperative complications were identified. Mechanical thrombectomy appears to be a safe and effective treatment for patients with recent trauma who have an intermediate-high risk pulmonary embolism.

Abstract
BACKGROUND Milligan-Morgan hemorrhoidectomy (MMH) is the most widely used surgical procedure because of its precise curative effect, but it has the disadvantages such as obvious postoperative pain and bleeding. To retrospectively evaluate the efficacy and safety of MMH combined with non-Doppler hemorrhoidal artery ligation (MMH + ND-HAL) for the treatment of grade III/IV hemorrhoids. METHODS We conducted a retrospective analysis of 115 patients with grade III/IV hemorrhoids, 53 patients had received MMH + ND-HAL, and the remaining 62 patients received MMH. We collected and compared demographic and clinical characteristics of both groups, including intraoperative blood loss, postoperative visual analog scale (VAS) for pain, analgesic consumption, postoperative bleeding, perianal incision edema, urinary retention, anal stenosis, anal incontinence incidence, recurrence rate (prolapse or bleeding), and patient satisfaction. RESULTS The VAS pain score of the first postoperative defecation and at the postoperative 12 h, 1 day, 2 days, 3 days, and 7 days, as well as the total analgesic consumption within 7 days, for the MMH + ND-HAL group were lower than those for the MMH group (P < 0.05). The intraoperative blood loss, the incidence of postoperative bleeding, perianal incision edema, and urinary retention in the MMH + ND-HAL group was lower than that in the MMH group (P < 0.05). No anal stenosis or anal incontinence occurred in either group. At follow-up by telephone or outpatient 12 months after surgery, the recurrence rate (prolapse or bleeding) was lower in the MMH + ND-HAL group than in the MMH group (P < 0.05), and satisfaction was higher in the MMH + ND-HAL group than in the MMH group (P < 0.05). CONCLUSIONS MMH + ND-HAL was a satisfactory surgical modality for treating III/IV hemorrhoids.

Abstract
BACKGROUND To evaluate the clinical efficacy and prognosis of unilateral biportal endoscopic lumbar fusion (ULIF) and minimally invasive transforaminal lumbar fusion (MIS-TLIF) for lumbar degenerative diseases. METHODS Chinese and English databases were retrieved for the period from database creation to December 31, 2022. Case-control studies on unilateral biportal endoscopic lumbar fusion were collected. The observation indexes consisted of operation times, intraoperative blood loss, postoperative drainage volume, length of hospital stay, postoperative pain score, postoperative oswestry disability index score, postoperative MacNab excellent and good rate, imaging fusion rate at the last follow-up, and complications. The NO rating table was employed to assess the quality of the included literature, and a meta-analysis was conducted using Revman5.4.1 and Stata17. RESULTS Ten studies with 738 surgical patients were considered, including 347 patients in the ULIF group and 391 in the MIS-TLIF group. This Meta-analysis demonstrated statistically significant differences in mean operation duration, intraoperative blood loss, postoperative drainage volume, length of hospital stay, and early postoperative (1-2W) visual analogue scale/score (VAS) scores for back pain. No significant differences were observed in the final follow-up postoperative VAS scores for back pain, postoperative leg VAS score, postoperative oswestry disability index score, excellent and good rate of postoperative modified MacNab, imaging fusion rate, and complications. CONCLUSION Compared with the MIS-TLIF group, the ULIF group had longer operation time, lower intraoperative blood loss and postoperative drainage volume, lower lumbar VAS score in the early postoperative period, and shorter hospital stay. ULIF is less invasive than traditional MIS-TLIF, making it a trustworthy surgical option for lumbar degenerative diseases with comparable fusion efficiency, superior MacNab rate, and complication rate.

Abstract
Management of malignant hemispheric stroke (MHS) after cardiothoracic surgery (CTS) remains difficult as decision-making needs to consider severe cardiovascular comorbidities and complex coagulation management. The results of previous randomized controlled trials on decompressive surgery for MHS cannot be generally translated to this patient population and the expected outcome might be substantially worse. Here, we analyzed mortality and functional outcome in patients undergoing decompressive hemicraniectomy (DC) for MHS following CTS and assessed the impact of perioperative coagulation management on postoperative hemorrhagic and cardiovascular complications. All patients that underwent DC for MHS resulting as a complication of CTS between June 2012 and November 2021 were included in this observational cohort study. Outcome was determined according to the modified Rankin Scale (mRS) score at 1 and 3-6 months. Clinical and demographic data, anticoagulation management and postoperative hemorrhagic and thromboembolic complications were assessed. In order to evaluate a predictive association between clinical and radiological parameters and the outcome, we used a multivariate logistic regression analysis. Twenty-nine patients undergoing DC for MHS after CTS with a female-to-male ratio of 1:1.9 and a median age of 60 (IQR 49-64) years were identified out of 123 patients undergoing DC for MHS. Twenty-four patients (83%) received pre- or intraoperative substitution. At 30 days, the in-hospital mortality rate and neurological outcome corresponded to 31% and a median mRS of 5 (5-6), which remained stable at 3-6 months [Mortality: 42%, median mRS: 5 (4-6)]. Postoperatively, 15/29 patients (52%) experienced new hemorrhagic lesions and Bayesian logistic regression predicting mortality (mRS = 6) after imputing missing data demonstrated a significantly increased risk for mortality with longer aPPT (OR = 13.94, p = .038) and new or progressive hemorrhagic lesions after DC (OR = 3.03, p = .19). Notably, all but one hemorrhagic lesion occurred before discontinued anticoagulation and/or platelet inhibition was re-initiated. Despite perioperative discontinuation of anticoagulation and/or platelet inhibition, no coagulation-associated cardiovascular complications were noted. In conclusion, Cardiothoracic surgery patients suffering MHS will likely experience severe neurological disability after DC, which should remain a central aspect during counselling and decision-making. The complex coagulation situation after CTS, however, should not per se rule out the option of performing life-saving surgical decompression.

Abstract
BACKGROUND We sought to study the impact of antithrombotics(antiplatelets and anticoagulants) on robotic ventral hernia repair(RVHR). METHODS RVHR cases were divided into antithrombotic (AT) (-) and AT (+) groups. After comparing both groups, a logistic regression analysis was performed. RESULTS 611 patients had no AT-medication. The AT(+) group had 219 patients of which 153 were only on antiplatelets, 52 only on anticoagulants, and 14(6.4%) patients on both antithrombotics. Mean age, American Society of Anesthesiology scores, and comorbidities were significantly higher in the AT(+) group. Intraoperative blood loss was greater in the AT(+) group. Postoperatively, the AT(+) group had greater rates of Clavien-Dindo grade-II and IV-a complications(p=0.001, and p=0.013, respectively), and postoperative hematomas(p=0.013). Mean follow-up was greater than 40 months. Age[Odds Ratio(OR): 1.034] and anticoagulants(OR: 3.121) were associated with increased bleeding-related events. CONCLUSION There were no associations between maintained antiplatelet therapy and postoperative bleeding-related events in RVHR whereas age and anticoagulants had the highest association.

Abstract
BACKGROUND Impairment of coagulation parameters and increased rate of thromboembolism are known complications of COVID-19 infection. In this study the coagulation profile and rate of thromboembolic events between two groups of patients who underwent spinal surgery before and after the COVID-19 pandemic was compared. PATIENTS AND METHOD Clinically and laboratory negative for COVID-19 elective patients before (n: 211) and during COVID- 19 pandemic (n: 294) with spinal surgeries were included in this retrospective study. Surgical characteristics, Physiologic parameters, coagulation parameters and thromboembolic events were compared between the two study groups. RESULTS Preoperative coagulation parameters, including PT, PTT, and INR were significantly increased during the COVID-19 pandemic (P < 0.001. P = 0.001, and P < 0.001, respectively), while the platelet count was significantly reduced (P = 0.04). The same differences were observed between the two study groups after the spinal surgery. In addition, respiratory rate and postoperative bleeding of the first postoperative 24 h was significantly more in patients who were operated on during COVID-19 outbreak (P = 0.03 and P = 0.002, respectively). The rate of thromboembolic events was 3.1% during the COVID-19 pandemic (seven PE, one DVT, and one MI) and 0% before that. This difference was statistically significant (P = 0.043). CONCLUSION The rate of thromboembolic events seems to be increased during the COVID-19 pandemic. These findings urge more stringent monitoring of the patients' coagulation parameters during the COVID-19 outbreak.

Abstract
BACKGROUND Flowable hemostatic agents have the advantage of being able to be applied to irregular wound surfaces and difficult to reach areas. We sought to compare the effectiveness and safety of the flowable hemostatic sealants Collastat® (collagen hemostatic matrix, [CHM]) and Floseal® (gelatin hemostatic matrix, [GHM]) during off-pump coronary artery bypass (OPCAB). METHODS In this prospective, double-blind, randomized controlled trial, 160 patients undergoing elective OPCAB surgery were enrolled between March 2018 and February 2020. After primary suture of the aortocoronary anastomosis, an area of hemorrhage was identified, and patients received either CHM or GHM (n = 80, each). Study endpoints were the following: proportion of successful intraoperative hemostasis and time required for hemostasis overall postoperative bleeding, proportion of transfusion of blood products, and surgical revision for bleeding. RESULTS Of the total patients, 23% were female, and the mean age was 63 years (range 42-81 years). Successful hemostasis proportion within 5 min was achieved for 78 patients (97.5%) in the GHM group, compared to 80 patients (100%) in the CHM group (non-inferiority p = 0.006). Two patients receiving GHM required surgical revision to achieve hemostasis. There were no differences in the mean time required to obtain hemostasis [GHM vs. CHM, mean 1.49 (SD 0.94) vs. 1.35 (0.60) min, p = 0.272], as confirmed by time-to-event analysis (p = 0.605). The two groups had similar amounts of mediastinal drainage for 24 h postoperatively [538.5 (229.1) vs. 494.7 (190.0) ml, p = 0.298]. The CHM group required less packed red blood cells, fresh frozen plasma, and platelets for transfusion than the GHM group (0.5 vs. 0.7 units per patient, p = 0.047; 17.5% vs. 25.0%, p = 0.034; 7.5% vs. 15.0%, p = 0.032; respectively). CONCLUSIONS CHM was associated with a lower need for FFP and platelet transfusions. Thus, CHM is a safe and effective alternative to GHM. TRIAL REGISTRATION ClinicalTrials.gov, NCT04310150.

Abstract
OBJECTIVES This study aimed to perform a multicenter comparison between robotic pancreaticoduodenectomy (RPD) and open pancreaticoduodenectomy (OPD). BACKGROUND Previous comparisons of RPD versus OPD have only been carried out in small, single-center studies of variable quality. METHODS Consecutive patients who underwent RPD (n = 1032) or OPD (n = 1154) at 7 centers in China between July 2012 and July 2020 were included. A 1:1 propensity score matching (PSM) was performed. RESULTS After PSM, 982 patients in each group were enrolled. The RPD group had significantly lower estimated blood loss (EBL) (190.0 vs 260.0 mL; P < 0.001), and a shorter postoperative 1length of hospital stay (LOS) (12.0 (9.0-16.0) days vs 14.5 (11.0-19.0) days; P < 0.001) than the OPD group. There were no significant differences in operative time, major morbidity including clinically relevant postoperative pancreatic fistula (CR-POPF), bile leakage, delayed gastric emptying, postoperative pancreatectomy hemorrhage (PPH), reoperation, readmission or 90-day mortality rates. Multivariable analysis showed R0 resection, CR-POPF, PPH and reoperation to be independent risk factors for 90-day mortality. Subgroup analysis on patients with pancreatic ductal adenocarcinoma (PDAC) (n = 326 in each subgroup) showed RPD had advantages over OPD in EBL and postoperative LOS. There were no significant differences in median disease-free survival (15.2 vs 14.3 months, P = 0.94) or median overall survival (24.2 vs 24.1 months, P = 0.88) between the 2 subgroups. CONCLUSIONS RPD was comparable to OPD in feasibility and safety. For patients with PDAC, RPD resulted in similar oncologic and survival outcomes as OPD.

Abstract
BACKGROUND To evaluate the efficacy and safety of novel plasma radio frequency generator and its single-use polypectomy snares for endoscopic mucosal resection (EMR) of gastrointestinal (GI) polyps. METHODS A total of 217 patients with 413 GI polyps were recruited from four centers in China. Patients were assigned to experimental or control groups using a central randomization method. The experimental group used the novel plasma radio frequency generator and its matched single-use polypectomy snares (Neowing, Shanghai), while the control group used the high-frequency electrosurgical unit (Erbe, Germany) and disposable electrosurgical snares (Olympus, Japan). The primary endpoint was the en bloc resection rate, and the non-inferiority margin was set at 10%. Secondary endpoint included operation time, coagulation success rate, intraoperative and postoperative bleeding rate, and perforation rate. RESULTS The en bloc resection rate was 97.20% (104/107) in the experimental group and 95.45% (105/110) in the control group (P = 0.496). The operation time was 29.14 ± 20.21 min in the experimental group and 30.26 ± 18.74 min in the control group (P = 0.671). The average removal time of a single polyp in the experimental group was 7.52 ± 4.45 min, which was slightly shorter than that in the control group 8.90 ± 6.67 min, with no statistical difference (P = 0.076). The intraoperative bleeding rates of the experimental group and control group were 8.41% (9/107) and 10.00% (11/110), respectively (P = 0.686). No intraoperative perforation occurred in either group. The postoperative bleeding rates of the experimental group and the control group were 1.87% (2/107) and 4.55% (5/110), respectively (P = 0.465). No postoperative perforation occurred in the experimental group (0/107), while one case of delayed perforation occurred in the control group (1/110, 0.91%). There was no statistical difference between the two groups. CONCLUSIONS Endoscopic mucosal resection of GI polyps with the novel plasma radio frequency generator is safe and effective, and non-inferior to the conventional high-frequency electrosurgical system.

Abstract
OBJECTIVES Bleeding remains a common complication post-thoracic surgery. Although intravenous tranexamic acid (TXA) has been shown to decrease blood loss, its use has been associated with adverse effects. Accordingly, topical TXA has been proposed as an alternative to reduce bleeding with fewer systemic complications. METHODS We searched Medline, Embase, and Cochrane Central databases for randomized controlled trials (RCTs) comparing topical TXA versus control (i.e., placebo) in patients undergoing thoracic procedures. The primary outcome was total postoperative blood loss at 24 hours. Secondary outcomes included were the number of red blood cell (RBC) transfusions, and hospital length of stay (LOS). Meta-analyses were pooled using mean difference with inverse-variance weighting and random-effects. RESULTS Out of the 575 unique studies that were screened, we identified three randomized controlled trials (RCTs) involving 399 patients. Out of the three RCTs analyzed, two studies, accounting for 67% of the total, were found to have a low risk of bias. The primary outcome of 24-h post-operative blood loss was significantly lower in patients who received TXA (mean difference [MD] -93.6 ml, 95% CI -121.8 to -65.4 ml, I2 = 45%). In addition, the need for RBC transfusion was significantly lower in the topical TXA group compared to control (MD -0.5 units, 95% CI -0.8 to -0.3 units, I2 = 60%). However, there was no significant difference in the hospital length of stay (LOS) (MD -0.3 days, 95% CI -0.9 to 0.4 days, I2 = 0%). These results remained consistent after several sensitivity analyses. The use of topical intrapleural tranexamic acid has also been found to be safe without any significant safety concerns. CONCLUSION Topical intrapleural TXA reduces blood loss and the need for blood transfusions during thoracic surgery. In addition, there is no evidence of the increased safety concerns associated with its use. Larger trials are necessary to validate these findings and evaluate the safety and efficacy of different dosages.

Abstract
OBJECTIVE To determine whether early (before skin closure) versus postoperative chemoprophylaxis affects the incidence of venous thromboembolism (VTE) and bleeding following major abdominal surgery, in a high thromboembolic risk population. BACKGROUND Major abdominal surgery incurs both VTE and bleeding risks. Patients with high preoperative VTE risk derive the most benefit from chemoprophylaxis, but carry an increased risk of bleeding. The optimal window for chemoprophylaxis in the perioperative period, whereby both VTE and bleeding risks are minimized, is unknown. METHODS Analysis of pooled data from 5 multicenter studies including only high thromboembolic risk (Caprini score >4) patients. Clinical VTE was defined as radiographically proven symptomatic disease <30 days postsurgery. Major bleeding was defined as the need for blood transfusion, reintervention, or >20 g/L fall in hemoglobin. RESULTS From 5501 cases, chemoprophylaxis was initiated early in 1752 (31.8%) patients and postoperatively in 3749 (68.2%) patients. Baseline characteristics were similar between study groups. The incidence of clinical VTE was not associated with chemoprophylaxis timing [early 0.7% vs. postop 0.7%, odds ratio (OR): 1.11, 95% confidence interval (CI): 0.60-2.15, P =0.730]. Contrastingly, compared with postoperative chemoprophylaxis, early usage increased the risk of all bleeding (5.1% vs. 2.6%, OR: 2.04, 95% CI: 1.52-2.73, P <0.001) major bleeding (3.6% vs. 1.8%, OR: 1.99, 95% CI: 1.40-2.81, P <0.001), and reintervention (2.0% vs. 1.0%, OR: 2.10, 95% CI: 1.32-3.35, P =0.003). Early chemoprophylaxis independently predicted postoperative bleeding (OR: 1.71, 95% CI: 1.25-2.34, P <0.001), but not VTE. CONCLUSIONS In high VTE risk patients undergoing major abdominal surgery, chemoprophylaxis commenced postoperatively reduces bleeding risk without affecting clinical VTE risk.

Abstract
OBJECTIVE To examine the relationship between enoxaparin dose adequacy, quantified with anti-Factor Xa (aFXa) levels, and 90-day symptomatic venous thromboembolism (VTE) and postoperative bleeding. SUMMARY BACKGROUND DATA Surgical patients often develop "breakthrough" VTE events-those which occur despite receiving chemical anticoagulation. We hypothesize that surgical patients with low aFXa levels will be more likely to develop 90-day VTE, and those with high aFXa will be more likely to bleed. METHODS Pooled analysis of eight clinical trials (N = 985) from a single institution over a 4 year period. Patients had peak steady state aFXa levels in response to a known initial enoxaparin dose, and were followed for 90 days. Survival analysis log-rank test examined associations between aFXa level category and 90-day symptomatic VTE and bleeding. RESULTS Among 985 patients, 2.3% (n = 23) had symptomatic 90-day VTE, 4.2% (n = 41) had 90-day clinically relevant bleeding, and 2.1% (n = 21) had major bleeding. Patients with initial low aFXa were significantly more likely to have 90-day VTE than patients with adequate or high aFXa (4.2% vs 1.3%, P = 0.007). In a stratified analysis, this relationship was significant for patients who received twice daily (6.2% vs 1.5%, P = 0.003), but not once daily (3.0% vs 0.7%, P = 0.10) enoxaparin. No association was seen between high aFXa and 90-day clinically relevant bleeding (4.8% vs 2.9%, P = 0.34) or major bleeding (3.6% vs 1.6%, P = 0.18). CONCLUSIONS This manuscript establishes inadequate enoxaparin dosing as a plausible mechanism for breakthrough VTE in surgical patients, and identifies anticoagulant dose adequacy as a novel target for process improvement measures.

Abstract
INTRODUCTION Acquired uterine arteriovenous malformation (uAVM) is a rare disease and could occur after dilation and curettage, cesarean section, or neoplastic processes. PATIENT CONCERNS A 29-year-old female presented with acute right lower abdominal pain and positive beta human chorionic gonadotropin (β-hCG). DIAGNOSIS A 6 cm ectopic right cornual pregnancy was found on ultrasound examination. INTERVENTIONS She underwent a laparoscopic resection of the cornual ectopic pregnancy. She returned with extensive vaginal bleeding 6-month post surgery, and eventually diagnosed with arteriovenous malformation at the previous surgical site by Color Dopplor endovaginal ultrasound. Percutaneous transcatheter uterine artery embolization (UAE) was attempted, however, vaginal bleeding continued. She was taken to the operation room for a hysteroscopic ablation of uAVM. OUTCOMES Complete cessation of the bleeding was achieved without hysterectomy. CONCLUSION We report an extremely unusual case of acquired uAVM after a wedge resection of cornual pregnancy. Ultrasound evaluation of patients with post-operative persistent bleeding should be considered for evaluation of a possible arteriovenous malformation.

Abstract
Simultaneous bilateral total hip arthroplasty (SBTHA) is an effective procedure for patients with disease bilaterally. But there is concern about increased blood loss and complications of SBTHA than staged total hip arthroplasty (THA). This study aimed to evaluate the differences in the clinical outcomes and complication rate of SBTHA with drainage and without drainage for reducing the concerns. Between October 2015 and April 2019, a retrospective cohort study was conducted with modified minimally invasive 2-incision method and a consecutive series of 41 SBTHA performed with drainage (Group I) were compared to 37 SBTHA performed without drainage (Group II). It was assessed clinically and radiographically for a mean of 2.1 ± 0.8 years (range, 1.0-4.8 years). Postoperative hematologic values (Hgb loss, total blood loss, transfusion rate), pain susceptibility, functional outcome (Harris Hip Score, Western Ontario and McMaster Universities Osteoarthritis Index score) and complication were compared in the drained group and the non-drained group. Postoperative Hgb loss (I: 2163.2 ± 698.7 g, II: 1730.4 ± 572.5 g; P = .002), total blood loss (I: 1528.8 ± 421.7 mL, II: 1237.6 ± 325.9 mL; P = .001) and mean transfusion unit (I: 0.7 ± 1.0 IU, II: 0.1 ± 0.3 IU; P < .001) were significantly lower in the without drainage group than in the with drainage group. But the morphine equivalent (I: 132.7 ± 314.1 mg, II: 732.2 ± 591.5 mg; P < .001) was significantly larger in the without drainage group. No significant difference was found between the drainage group and without drainage group in Harris Hip Score and Western Ontario and McMaster Universities Osteoarthritis Index score at final follow-up. SBTHA without drainage can reduce postoperative blood loss and the requirement for transfusion without increasing other complication. But SBTHA without drainage is more painful method than SBTHA with drainage. Therefore, SBTHA without drainage will be a good option to reduce the burden on the patient by reducing postoperative bleeding if it can control pain well after surgery.

Abstract
OBJECTIVE To investigate the clinical application of two elastic pedicle internal fixation systems in single-segment lumbar disc herniation fenestration. METHODS A retrospective analysis of 64 patients with lumbar intervertebral disc herniation treated by surgery from June 2019 to March 2021. According to the different elastic fixation systems placed during the operation, the patients were divided into ordinary pedicle screw elastic rod link group (elastic rod group) and a special elastic pedicle screw rigid rod fixed connection group (elastic screw group). There were 33 cases in the elastic rod group, including 18 males and 15 females, aged from 30 to 69 years old with an average of(49.18±10.23) years old;and 31 cases in the elastic screw group, including 16 males and 15 females, aged from 32 to 68 with an average of (49.81±9.24) years old. The operation time, intraoperative blood loss, postoperative wound drainage, and postoperative landing time of the two groups were recorded separately. The visual analogue scale (VAS), Japanese Orthopaedic Association (JOA) score, and Oswestry Disability Index (ODI) were compared before and 3, 12 months after operation. The height of the adjacent vertebral space on the lateral DR film before and 12 months after the operation was measured. The clinical efficacy was evaluated by Macnab standard. RESULTS All the patients successfully completed the operation, and were followed up. The operation time, intraoperative blood loss, postoperative wound drainage and postoperative landing time in the elastic rod group were(63.73±12.01) min, (89.55±16.07) ml, (81.67±16.00) ml, (3.45±0.75) d , while in the elastic nail group was (62.96±11.54) min, (88.35±17.14) ml, (82.29±15.40) ml, (3.29±0.78) d, the difference was not statistically significant. The symptoms of low back pain and lower extremity numbness were significantly improved in all patients after operation. There was no significant difference in VAS, JOA score and ODI between the two groups before and after surgery (P>0.05). At 12 months after operation, there was no significant difference in the height of the adjacent vertebral space between the upper adjacent vertebral body and the same segment before operation(P>0.05), and there was no significant difference between the groups before and after the operation. According to Macnab criteria, the elastic rod group was excellent in 30 cases, good in 2 cases, fair in 1 case, while the elastic nail group was excellent in 29 cases, good in 2 cases, fair in 0 cases, and there was no significant difference(Z=-0.42, P=0.68). CONCLUSION In fenestrated nucleus pulposus extraction for lumbar disc herniation, the two elastic pedicle internal fixation systems are equally effective and can be used. The elastic screw internal fixation system has certain advantages when the distance between the two vertebral bodies is short, and the elastic rod cannot be placed or is difficult to be placed, and it is more widely used.

Abstract
OBJECTIVE To determine the efficacy and safety of extended duration perioperative thromboprophylaxis by low molecular weight heparin when assessing disease-free survival in patients undergoing resection for colorectal cancer. DESIGN Multicentre, open label, randomised controlled trial. SETTINGS 12 hospitals in Quebec and Ontario, Canada, between 25 October 2011 and 31 December 2020. PARTICIPANTS 614 adults (age ≥18 years) were eligible with pathologically confirmed invasive adenocarcinoma of the colon or rectum, no evidence of metastatic disease, a haemoglobin concentration of ≥8 g/dL, and were scheduled to undergo surgical resection. INTERVENTIONS Random assignment to extended duration thromboprophylaxis using daily subcutaneous tinzaparin at 4500 IU, beginning at decision to operate and continuing for 56 days postoperatively, compared with in-patient postoperative thromboprophylaxis only. MAIN OUTCOME MEASURES Primary outcome was disease-free survival at three years, defined as survival without locoregional recurrence, distant metastases, second primary (same cancer), second primary (other cancer), or death. Secondary outcomes included venous thromboembolism, postoperative major bleeding complications, and five year overall survival. Analyses were done in the intention-to-treat population. RESULTS The trial stopped recruitment prematurely after the interim analysis for futility. The primary outcome occurred in 235 (77%) of 307 patients in the extended duration group and in 243 (79%) of 307 patients in the in-hospital thromboprophylaxis group (hazard ratio 1.1, 95% confidence interval 0.90 to 1.33; P=0.4). Postoperative venous thromboembolism occurred in five patients (2%) in the extended duration group and in four patients (1%) in the in-hospital thromboprophylaxis group (P=0.8). Major surgery related bleeding in the first postoperative week was reported in one person (<1%) in the extended duration and in six people (2%) in the in-hospital thromboprophylaxis group (P=0.1). No difference was noted for overall survival at five years in 272 (89%) patients in the extended duration group and 280 (91%) patients in the in-hospital thromboprophylaxis group (hazard ratio 1.12; 95% confidence interval 0.72 to 1.76; P=0.1). CONCLUSIONS Extended duration to perioperative anticoagulation with tinzaparin did not improve disease-free survival or overall survival in patients with colorectal cancer undergoing surgical resection compared with in-patient postoperative thromboprophylaxis alone. The incidences of venous thromboembolism and postoperative major bleeding were low and similar between groups. TRIAL REGISTRATION ClinicalTrials.gov NCT01455831.
