Lee E, Lee JW, Kang HS. Interlaminar versus transforaminal epidural steroid injections: a review of efficacy and safety. Skeletal Radiol 2023; 52:1825-1840. [PMID: 35859019 DOI: 10.1007/s00256-022-04124-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2022] [Revised: 07/09/2022] [Accepted: 07/11/2022] [Indexed: 02/02/2023]
Abstract
Spine intervention is an important treatment option for the management of spinal pain, and the numbers of the most representative epidural steroid injection (ESI) procedures performed are expected to increase significantly in the future along with increased life expectancy and the increasing prevalence of spinal disorders. Therefore, it is important to understand the efficacy of ESIs according to each spinal disorder they are administered to treat, and one must be familiar with the possible complications. In fact, although numerous ESI-related articles have been published, there is still considerable controversy regarding the efficacy of ESI procedures. Furthermore, due to the rarity of serious complications, most instances have been recorded in the form of case reports. In this article, we aimed to review the indications of cervical and lumbar ESIs and to compare interlaminar ESI (ILESI) and transforaminal ESI (TFESI) techniques in terms of analgesic efficacy, possible complications, and safety profiles. This article includes opinions based on the authors' experience with ESI indications and efficacy, and presents practical tips for coping with specific situations related to each complication. By combining the dedicated anatomical understanding of radiologists with image-guided interventions, ESI is expected to stand out in the rapidly expanding field of spine intervention.

Safety of lumbar puncture for people who are treated with ADP receptor antagonists. J Neurol 2023; 270:3052-3057. [PMID: 36813930 DOI: 10.1007/s00415-023-11628-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Revised: 02/13/2023] [Accepted: 02/14/2023] [Indexed: 02/24/2023]
Abstract
BACKGROUND Current guidelines state that clopidogrel and other adenosine-diphosphate receptor antagonists (ADPra) should be stopped for at least 7 days before lumbar puncture (LP). This practice may delay the diagnosis of treatable neurological emergencies and may increase the risk of cardiovascular morbidity due to withholding antiplatelets. We aimed to summarize all cases under our care, in which LP was performed without discontinued ADPra. METHODS A retrospective case series study of all patients who underwent LP without interruption of ADPRa or with treatment interruption that was shorter than 7 days. Medical records were searched for documented complications. Traumatic tap was defined as cerebrospinal fluid red cell count ≥ 1000 cell/μL. Incidence of traumatic tap among people who underwent LP under ADPRa was compared to traumatic tap incidence in two control groups: LP under aspirin and LP without any anti-platelet. RESULTS 159 patients underwent LP under ADPRa [Age: 68.4 ± 12.1, Female: 63 (40%), 81 (51%) were treated with both aspirin and ADPRa]. 116 procedures were carried out without any interruption of ADPRa. In the other 43, the median delay between treatment interruption and the procedure was 2 days (range: 1-6 days). Incidence of traumatic tap was 8/159 (5%), 9/159 (5.7%) and 4/160 (2.5%) among those who underwent LP under ADPRa, under aspirin and without any anti-platelet, respectively. [X2(2) = 2.13, P = 0.35)]. No patient developed spinal hematoma or any neurological deficit. CONCLUSIONS Lumbar puncture without discontinuation of ADP receptor antagonists seems safe. Similar case series may ultimately lead to guidelines change.

Abstract
BACKGROUND Bleeding is a potential complication after neuraxial and peripheral nerve blocks. The risk is increased in patients on antiplatelet and anticoagulant drugs. This joint guideline from the European Society of Anaesthesiology and Intensive Care and the European Society of Regional Anaesthesia aims to provide an evidence-based set of recommendations and suggestions on how to reduce the risk of antithrombotic drug-induced haematoma formation related to the practice of regional anaesthesia and analgesia. DESIGN A systematic literature search was performed, examining seven drug comparators and 10 types of clinical intervention with the outcome being peripheral and neuraxial haematoma. Grading of Recommendations, Assessment, Development and Evaluation (GRADE) was used for assessing the methodological quality of the included studies and for formulating recommendations. A Delphi process was used to prepare a clinical practice guideline. RESULTS Clinical studies were limited in number and quality and the certainty of evidence was assessed to be GRADE C throughout. Forty clinical practice statements were formulated. Using the Delphi-process, strong consensus (>90% agreement) was achieved in 57.5% of recommendations and consensus (75 to 90% agreement) in 42.5%. DISCUSSION Specific time intervals should be observed concerning the adminstration of antithrombotic drugs both prior to, and after, neuraxial procedures or those peripheral nerve blocks with higher bleeding risk (deep, noncompressible). These time intervals vary according to the type and dose of anticoagulant drugs, renal function and whether a traumatic puncture has occured. Drug measurements may be used to guide certain time intervals, whilst specific reversal for vitamin K antagonists and dabigatran may also influence these. Ultrasound guidance, drug combinations and bleeding risk scores do not modify the time intervals. In peripheral nerve blocks with low bleeding risk (superficial, compressible), these time intervals do not apply. CONCLUSION In patients taking antiplatelet or anticoagulant medications, practitioners must consider the bleeding risk both before and after nerve blockade and during insertion or removal of a catheter. Healthcare teams managing such patients must be aware of the risk and be competent in detecting and managing any possible haematomas.

Abstract
The development of protocols to prevent perioperative Venous Thromboembolism (VTE) and the introduction of increasingly potent antithrombotic drugs have resulted in concerns of increased risk of neuraxial bleeding. Since the Brazilian Society of Anesthesiology (SBA) 2014 guideline, new oral anticoagulant drugs were approved by international regulating agencies, and by ANVISA. Societies and organizations that try to approach concerns through guidelines have presented conflicting perioperative management recommendations. As a response to these issues and to the need for a more rational approach, managements were updated in the present narrative revision, and guideline statements made. They were projected to encourage safe and quality patient care, but cannot assure specific results. Like any clinical guide recommendation, they are subject to review as knowledge grows, on specific complications, for example. The objective was to assess safety aspects of regional analgesia and anesthesia in patients using antithrombotic drugs, such as: possible technique-associated complications; spinal hematoma-associated risk factors, prevention strategies, diagnosis and treatment; safe interval for discontinuing and reinitiating medication after regional blockade.

Abstract
Abstract
Objectives
To determine prevalence rates of hemorrhagic complications in patients who either ceased or continued anticoagulants during interventional pain procedures.
Methods
A total of 1,936 consecutive patients were prospectively monitored during a total of 12,723 injection procedures. The prevalence of hemorrhagic complications was tallied for a variety of procedures performed on patients who ceased or continued various anticoagulants.
Results
No hemorrhagic complications occurred in any patient who continued anticoagulants. Sufficiently large sample sizes were obtained to conclude that, in patients who continued warfarin or clopidrogel during lumbar transforaminal injections and for lumbar facet procedures, the zero prevalence of complications had 95% confidence intervals of 0% to 0.3%. This prevalence was significantly lower than the risk of medical complications in patients who ceased warfarin.
Conclusions
Lumbar transforaminal injections and lumbar facet injections have a very low rate of hemorrhagic complications when patients continue to take anticoagulants.

Abstract
Lumbar puncture (LP) is an important and frequently performed invasive procedure for the diagnosis and management of neurological conditions. There is little in the neurological literature on the topic of periprocedural management of antithrombotics in patients undergoing LP. Current practice is therefore largely extrapolated from guidelines produced by anaesthetic bodies on neuraxial anaesthesia, haematology groups advising on periprocedural management of antiplatelet agents and anticoagulants, and by neuroradiology on imaging-guided spinal procedures. This paper summarises the existing literature on the topic and offers recommendations to guide periprocedural antithrombotic management for LP, based on the consolidation of the best available evidence.

Abstract
BACKGROUND AND OBJECTIVES Interventional pain procedures are commonly performed on patients receiving antiplatelet therapy. However, there is limited evidence to support or refute the safety of this practice. The goal of this investigation was to assess the rate of bleeding complications in a large cohort of patients undergoing intermediate- and low-risk pain procedures, with a specific focus on antiplatelet and anticoagulant medication use and baseline coagulation abnormalities. METHODS This is a retrospective cohort study of adult patients undergoing low- and intermediate-risk pain procedures from 2005 through 2014 by the division of pain medicine at a single academic tertiary care center. Baseline characteristics, antiplatelet and anticoagulant medication use, coagulation parameters, and procedural details were extracted from the electronic medical record. The primary outcome was a bleeding-related complication requiring emergency medicine, neurology, or neurosurgical evaluation within 31 days. The secondary outcome was the presence or absence of a periprocedural red blood cell transfusion occurring within 72 hours of needle placement. RESULTS A total of 58,066 procedures were performed on 24,590 unique patients. Preprocedural aspirin or nonsteroidal anti-inflammatory drug therapy was present for 17,825 procedures (30.7%). Sixteen procedures were associated with perioperative red blood cell transfusion (0.03%), with no difference based on preprocedural nonsteroidal anti-inflammatory drug, including aspirin, or other anticoagulation use (P = 0.107). Five patients (0.009%) had a neurologic complication requiring further evaluation, of which 2 were likely related to procedural bleeding. CONCLUSIONS Bleeding complications are rare in patients undergoing low- or intermediate-risk pain procedures even in the presence of antiplatelet medications. This is consistent with recently released guidelines.

Abstract
Background Guidelines have been published that recommend discontinuing anticoagulants in patients undergoing interventional pain procedures. The safety and effectiveness of these guidelines have not been tested. Objectives The present study was performed to determine if continuing or discontinuing anticoagulants for pain procedures is associated with a detectable risk of complications. Methods An observational study was conducted in a private practice in which some partners continued anticoagulants while other partners routinely discontinued anticoagulants. Results No complications attributable to anticoagulants were encountered in 4,766 procedures in which anticoagulants were continued. In 2,296 procedures in which anticoagulants were discontinued according to the guidelines, nine patients suffered serious morbidity, including two deaths. Conclusions Lumbar transforaminal injections, lumbar medial branch blocks, trigger point injections, and sacroiliac joint blocks appear to be safe in patients who continue anticoagulants. In patients who discontinue anticoagulants, although low (0.2%) the risk of serious complications is not zero, and must be considered when deciding between continuing and discontinuing anticoagulants.

Abstract
Image-guided spinal injection is commonly performed in symptomatic patients to decrease pain severity, confirm the pain generator, and delay or avoid surgery. This article focuses on the radiologist as spine interventionist and addresses the following four topics relevant to the radiologist who performs corticosteroid injections for pain management: (a) the rationale behind corticosteroid injection, (b) the interaction with patients, (c) the role of imaging in procedural selection and planning, and (d) the pearls and pitfalls of fluoroscopically guided injections. Factors that contribute to the success of a pain management service include communication skills and risk mitigation. A critical factor is the correlation of clinical symptoms with magnetic resonance (MR) imaging findings. Radiologists can leverage their training in MR image interpretation to distinguish active pain generators in the spine from incidental abnormalities. Knowledge of fluoroscopic anatomy and patterns of contrast material flow guide the planning and execution of safe and effective needle placement. © RSNA, 2016 Online supplemental material is available for this article.

Abstract
Escalating costs and change in the profile of patients presenting for cardiac surgery requires modification of perioperative management strategies. Regional anesthesia has played an integral part of many fast-track anesthesia protocols across North America and Europe. This review suggests that for patients undergoing coronary artery bypass graft surgery, the risk-to-benefit ratio is in favor of epidural and spinal anesthesia, provided there are no specific contraindications and the guidelines for the use of regional techniques in cardiac surgery are followed. Patients managed with regional techniques seem to benefit from superior postoperative analgesia, shorter postoperative ventilation, reduced incidence of supraventricular arrhythmia, and lower rates of perioperative myocardial infarction. The results of this analysis suggest that for each episode of neurologic complication, 20 myocardial infarctions and 76 episodes of atrial fibrillation would be prevented, thus, we would consider the regional anesthesia and analgesia to be an effective strategy that improves perioperative morbidity. However, other treatment modalities such as the addition of calcium channel blockers, aspirin, and beating heart surgery, are also suggested to be beneficial in cardiac surgical patients and may impose less risk than the use of regional techniques. We believe that the results presented in this review are encouraging enough to permit continued investigation. A prospective, randomized, controlled multicenter trial needs to be adequately powered to answer important clinical questions and allow for a long-term follow-up.

Abstract
Acute pain management is improving steadily over the past few years, but training and professional education are still lacking in many professions. Untreated or undertreated acute pain could have detrimental effects on the patient in terms of comfort and recovery from trauma or surgery. Acute undertreated pain can decrease a patient's vascular perfusion, increase oxygen demand, suppress the immune system, and possibly risk increased incidence of venous thrombosis. Although acute postoperative pain needs to be managed aggressively, patients are most vulnerable during this period for developing adverse effects, and therefore, patient assessment and careful drug therapy evaluation are necessary processes in therapeutic planning. Acute pain management requires careful and thorough initial assessment and follow-up reassessment in addition to frequent dosage adjustments, and managing analgesic induced side effects. Analgesic selection and dosing must be based on the patient's past and recent analgesic exposure. There is no single acute pain management regimen that is suitable for all patients. Analgesics must be tailored to the individual patient.

Abstract
PURPOSE OF REVIEW Epidural steroid injections (ESIs) are the most commonly performed intervention in pain clinics across the USA and worldwide. In light of the growing use of ESIs, a recent spate of highly publicized infectious complications, and increasing emphasis on cost-effectiveness, the utility of ESI has recently come under intense scrutiny. This article provides an evidence-based review of ESIs, including the most up-to-date information on patient selection, comparison of techniques, efficacy, and complications. RECENT FINDINGS The data strongly suggest that ESIs can provide short-term relief of radicular symptoms but are less convincing for long-term relief, and mixed regarding cost-effectiveness. Although some assert that transforaminal ESIs are more efficacious than interlaminar ESIs, and that fluoroscopy can improve treatment outcomes, the evidence to support these assertions is limited. SUMMARY The cost-effectiveness of ESI is the subject of great debate, and similar to efficacy, the conclusions one draws appear to be influenced by specialty. Because of the wide disparities regarding indications and utilization, it is likely that indiscriminate use is cost-ineffective, but that judicious use in well-selected patients can decrease healthcare utilization. More research is needed to better refine selection criteria for ESI, and to determine which approach, what dose, and how many injections are optimal.

Abstract
Epidural steroid injections (ESIs) are the most widely utilized pain management procedure in the world, their use supported by more than 45 placebo-controlled studies and dozens of systematic reviews. Despite the extensive literature on the subject, there continues to be considerable controversy surrounding their safety and efficacy. The results of clinical trials and review articles are heavily influenced by specialty, with those done by interventional pain physicians more likely to yield positive findings. Overall, more than half of controlled studies have demonstrated positive findings, suggesting a modest effect size lasting less than 3 months in well-selected individuals. Transforaminal injections are more likely to yield positive results than interlaminar or caudal injections, and subgroup analyses indicate a slightly greater likelihood for a positive response for lumbar herniated disk, compared with spinal stenosis or axial spinal pain. Other factors that may increase the likelihood of a positive outcome in clinical trials include the use of a nonepidural (eg, intramuscular) control group, higher volumes in the treatment group, and the use of depo-steroid. Serious complications are rare following ESIs, provided proper precautions are taken. Although there are no clinical trials comparing different numbers of injections, guidelines suggest that the number of injections should be tailored to individual response, rather than a set series. Most subgroup analyses of controlled studies show no difference in surgical rates between ESI and control patients; however, randomized studies conducted by spine surgeons, in surgically amenable patients with standardized operative criteria, indicate that in some patients the strategic use of ESI may prevent surgery.

Abstract
The actual incidence of neurological dysfunction resulting from haemorrhagic complications associated with neuraxial block is unknown. Although the incidence cited in the literature is estimated to be <1 in 150,000 epidural and <1 in 220,000 spinal anaesthetics, recent surveys suggest that the frequency is increasing and may be as high as 1 in 3000 in some patient populations. Overall, the risk of clinically significant bleeding increases with age, associated abnormalities of the spinal cord or vertebral column, the presence of an underlying coagulopathy, difficulty during needle placement, and an indwelling neuraxial catheter during sustained anticoagulation (particularly with standard unfractionated heparin or low molecular weight heparin). The decision to perform spinal or epidural anaesthesia/analgesia and the timing of catheter removal in a patient receiving antithrombotic therapy is made on an individual basis, weighing the small, although definite risk of spinal haematoma with the benefits of regional anaesthesia for a specific patient. Coagulation status should be optimized at the time of spinal or epidural needle/catheter placement, and the level of anticoagulation must be carefully monitored during the period of neuraxial catheterization. Indwelling catheters should not be removed in the presence of therapeutic anticoagulation, as this appears to significantly increase the risk of spinal haematoma. Vigilance in monitoring is critical to allow early evaluation of neurological dysfunction and prompt intervention. An understanding of the complexity of this issue is essential to patient management.

Abstract
Cardiovascular disease is prevalent in patients undergoing orthopedic surgery. Many patients who have undergone previous percutaneous coronary intervention (PCI) with stenting are on dual antiplatelet therapy in order to minimize the risk of stent thrombosis. The optimal management of these patients in the perioperative setting remains unclear. We aim to provide information about the management of patients who have undergone a PCI with stents who are subsequently indicated for an orthopedic procedure. We will review the concerns from a cardiologist's and orthopedic surgeon's perspective in regards to the management of these patients in the perioperative setting. In addition, the current American Heart Association, American College of Cardiology, Society for Cardiovascular Angiography and Interventions, and American College of Surgeons guidelines are reviewed. The decision to discontinue dual antiplatelet therapy in a patient who has undergone a PCI with stent should be made only after careful review of the risks for thrombosis and bleeding. Best practice suggests that these risks should be jointly assessed by the orthopedic surgeon and cardiologist. Those patients with stents at high risk of thrombosis should have surgery delayed if possible. There is little data supporting a significantly increased bleeding risk associated with mortality in orthopedic patients when antiplatelet therapy is continued perioperatively.

Abstract
The actual incidence of neurologic dysfunction resulting from hemorrhagic complications associated with neuraxial blockade is unknown. Although the incidence cited in the literature is estimated to be less than 1 in 150,000 epidural and less than 1 in 220,000 spinal anesthetics, recent epidemiologic surveys suggest that the frequency is increasing and may be as high as 1 in 3000 in some patient populations.Overall, the risk of clinically significant bleeding increase with age,associated abnormalities of the spinal cord or vertebral column, the presence of an underlying coagulopathy, difficulty during needle placement,and an indwelling neuraxial catheter during sustained anticoagulation( particularly with standard heparin or low-molecular weight heparin). The need for prompt diagnosis and intervention to optimize neurologic outcome is also consistently reported. In response to these patient safety issues, the American Society of Regional Anesthesia and Pain Medicine (ASRA) convened its Third Consensus Conference on Regional Anesthesia and Anticoagulation. Practice guidelines or recommendations summarize evidence-based reviews. However, the rarity of spinal hematoma defies a prospective randomized study, and there is no current laboratory model. As a result,the ASRA consensus statements represent the collective experience of recognized experts in the field of neuraxial anesthesia and anticoagulation. These are based on case reports, clinical series, pharmacology,hematology, and risk factors for surgical bleeding. An understanding of the complexity of this issue is essential to patient management.

Abstract
The widespread use of central neuraxial block (CNB) and the prevalence of anticoagulation for different indications have led to an inevitable overlap between the two. The most serious complication of CNB in anticoagulated patients is the risk of spinal/epidural haematoma. Performing CNB in these patients is a complex decision that should take into account the twin risks of bleeding and venous/arterial thrombosis if anticoagulation therapies were to be stopped. Various guidelines have been issued to achieve normal haemostasis and thus allow safe administration of CNB. However, the evidence base for many such recommendations is weak, relying mainly on case reports, small studies and pharmacokinetics of the drugs. Given these limitations it is crucial to fully assess individual risk factors and understand anticoagulant pharmacokinetics in order to appropriately set time intervals for catheter insertion/removal. This paper will review traditional and newer anticoagulation/antiplatelet therapies with a view to improving the management of anticoagulated patients undergoing CNB.

Abstract
OBJECTIVE Since the previous comprehensive radiology review on coagulation concepts that was done in 1990, many studies have been published in the medical and surgical literature that can guide the approach of a radiology practice. The purpose of this article is to provide an analysis of these works, updating the radiologist on proper use and interpretation of coagulation assessment tools, medications that modify the hemostatic system, and the use of transfusions prior to interventions. CONCLUSION The basic tools for coagulation assessment have not changed; however, results from subspecialty research have suggested ways in which the use of these tools can be modified and streamlined to safely reduce time and expense for the patient and the health care system.

Abstract
Epidural steroid injections are relatively safe procedures, although the risk of hemorrhagic complications in patients undergoing long-term anticoagulation therapy is higher. The American Society for Regional Anesthesia and Pain Medicine has specific guidelines for treatment of these patients when they undergo neuraxial anesthetic procedures. In this paper, the authors present a case in which the current American Society for Regional Anesthesia and Pain Medicine guidelines were strictly followed with respect to withholding and reintroducing warfarin and enoxaparin after an epidural steroid injection, but the patient nevertheless developed a spinal epidural hematoma requiring emergency surgical evacuation. The authors compare the case with the 8 other published cases of postinjection epidural hematomas in patients with coagulopathy, and the specific risk factors that may have contributed to the hemorrhagic complication in this patient is analyzed.

Abstract
Lumbar interlaminar and transforaminal epidural injections are used in the treatment of lumbar radicular pain and other lumbar spinal pain syndromes. Complications from these procedures arise from needle placement and the administration of medication. Potential risks include infection, hematoma, intravascular injection of medication, direct nerve trauma, subdural injection of medication, air embolism, disc entry, urinary retention, radiation exposure, and hypersensitivity reactions. The objective of this article is to review the complications of lumbar interlaminar and transforaminal epidural injections and discuss the potential pitfalls related to these procedures. We performed a comprehensive literature review through a Medline search for relevant case reports, clinical trials, and review articles. Complications from lumbar epidural injections are extremely rare. Most if not all complications can be avoided by careful technique with accurate needle placement, sterile precautions, and a thorough understanding of the relevant anatomy and contrast patterns on fluoroscopic imaging.

Abstract
Nonsteroidal anti-inflammatory drugs (NSAIDs) cause gastrointestinal (GI) damage primarily due to the inhibition of prostaglandin synthesis in gastric mucosa, which is an important factor in mucosa protection. Platelets are a cardinal feature of vascular repair. A variety of angiogenic stimulators are stored in platelets and are released during clotting at the wound. When there is a defect in any of these functions and/or platelet number, haemostasis is usually impaired and there may be an associated increased risk and severity of bleeding. While the mechanism of mucosal injury and bleeding are well documented with the use of NSAIDs, very little is known about the platelet function abnormalities and their effects on severity of upper GI bleedings. We performed a prospective analysis of 49 patients who had a history of NSAIDs use to investigate the association between the platelet function impairment associated with NSAIDs and severity of upper GI haemorrhages. Thirty-six of 49 patients (73.5%) had deteriorated platelet function. Mean severity score of patients with deteriorated platelet functions was 3.39, and that of patients with normal platelet functions was 2.46. Mean severity score was statistically significantly higher in patients with deteriorated platelet functions. In conclusion, impaired platelet functions associated with NSAIDs may cause more severe upper GI bleeding. Clinicians should be alert for GI complications especially in older patients and in those with a history of ulcer bleeding.

Abstract
Lumbar epidural steroid injections are used to manage low back and leg pain (ie, sciatica). Utilization of the procedure is increasing, with Medicare spending for lumbar epidural procedures topping $175 million annually. Few prospective randomized controlled trials have clearly demonstrated the efficacy of epidural steroid injections; many have shown conflicting results. Several studies show favorable short-term outcomes with epidural steroid injection for radicular pain, but less conclusive results are achieved >6 months. Methodologic flaws limit interpretation of results from most scientific studies. As a tool for predicting surgical outcome, epidural spinal injection has been found to have a sensitivity between 65% and 100%, a specificity between 71% and 95%, and a positive predictive value as high as 95% for 1-year surgical outcome. Despite inconclusive evidence, when weighing the surgical alternatives and associated risk, cost, and outcomes, lumbar epidural steroid injections are a reasonable nonsurgical option in select patients.

Abstract
PURPOSE OF REVIEW Antithrombotic drugs are known to increase the risk of spinal epidural hematoma after neuraxial blockade. During the last few years, several new anticoagulants have been introduced, some of them more potent than the drugs currently available. More potency, however, may also indicate a higher risk of bleeding. RECENT FINDINGS Case series from the last few years indicate that spinal epidural hematoma is more common then previously estimated, with a prevalence from 1: 100,000 in obstetric patients to as high as 1: 3,600 in female orthopedic patients. In order to diminish this risk, most national societies have issued guidelines in which time intervals were established between administration of antithrombotic drugs and performance of neuraxial blockade. SUMMARY Guidelines are perceived to be capable of reducing the incidence of spinal epidural hematoma with the inherent risk of permanent paraplegia. These guidelines, however, will only be a valuable aid for clinicians if they are constantly updated and newer antithrombotic drugs are included. Although the resurge of peripheral nerve blocks may diminish patient hazards, deep nerve blocks such as lumbar sympathetic blockade are not devoid of serious complications and should probably be handled in the same way as neuraxial blockade.

Abstract
Growing evidence suggests that perioperative withdrawal of ASA for secondary stroke prevention increases thromboembolic risk without the associated benefit of decreased bleeding complications. ASA maintenance is acceptable in many procedures, including invasive ones. Many procedures, in particular ophthalmologic, dermatologic, and dental surgeries, also are safe while continuing oral AC. Warfarin has been continued successfully even in some surgeries that have high bleeding risk. When the risk is too high, temporary bridging therapy with LWMH is safe in many populations. Although the exact thromboembolic risks associated with temporary cessation of AP and AC are unknown and likely low, morbidity and mortality associated with thromboembolism are high. Further studies investigating the risks and benefits of maintaining AP and AC during procedures, particularly invasive ones, are needed. Meanwhile, it is critical that physicians understand the risks and benefits of perioperative AP and AC and the variety of procedures in which these agents can be safely continued.

Abstract
INTRODUCTION Stopping aspirin prior to transurethral prostatectomy (TURP) may minimise peri-operative blood loss, but it may also increase the risk of a significant cardiovascular event. There are no guidelines on the management of aspirin in TURP. This study sought to determine the variation in the peri-operative management of transurethral prostatectomy (TURP) patients that are taking aspirin. MATERIALS AND METHODS A questionnaire was sent to 444 consultant urologists in the UK from a list obtained from the British Association of Urologists. This resulted in 290 anonymous replies (65%), of which 287 were suitable for analysis. RESULTS Of these 287 urologists, 178 (62%) ask patients to stop aspirin prior to TURP. Aspirin is stopped 9.8 days (median, 10 days; range, 2-30 days) prior to surgery, and recommenced 8.8 days (median, 7 days; range, 1-42 days) after surgery. In those that stop aspirin, 62% will stop aspirin in all patients, regardless of the indication, and 40% will cancel a TURP if aspirin use has inadvertently continued. Of the 287 urologists, 109 (38%) do not stop aspirin. CONCLUSIONS There is a wide variation in the management of aspirin in TURP patients in the UK. Aspirin is being stopped in patients at high risk of serious cardiovascular disease, often for longer than necessary. There is a need for multidisciplinary guidelines to reduce variation in practice.

Abstract
Rheumatic diseases in women of childbearing years may necessitate drug treatment during a pregnancy, to control maternal disease activity and to ensure a successful pregnancy outcome. This survey is based on a consensus workshop of international experts discussing effects of anti-inflammatory, immunosuppressive and biological drugs during pregnancy and lactation. In addition, effects of these drugs on male and female fertility and possible long-term effects on infants exposed to drugs antenatally are discussed where data were available. Recommendations for drug treatment during pregnancy and lactation are given.

Abstract
OBJECTIVES Low-dose aspirin given for secondary prevention of cardiovascular disease is frequently withdrawn prior to surgical or diagnostic procedures to reduce bleeding complications. This may expose patients to increased cardiovascular morbidity and mortality. Aim of the study was to review and quantify cardiovascular risks because of periprocedural aspirin withdrawal and bleeding risks with the continuation of aspirin. METHODS We screened MEDLINE (January 1970-October 2004) with additional manual cross-referencing for clinical studies, surveys on the opinions of doctors and guidelines. RESULTS Studies reporting the relative risk of acute cardiovascular events after aspirin withdrawal when compared with its continuation were not found. However, retrospective investigations revealed that aspirin withdrawal precedes up to 10.2% of acute cardiovascular syndromes. The time interval between discontinuation and acute cerebral events was 14.3 +/- 11.3 days, 8.5 +/- 3.6 days for acute coronary syndromes, and 25.8 +/- 18.1 days for acute peripheral arterial syndromes (P < 0.02 versus acute coronary syndromes). On aspirin-related bleeding risks, we obtained 41 (12 observational retrospective, 19 observational prospective, 10 randomized) studies, reporting on 49 590 patients (14 981 on aspirin). Baseline frequency of bleeding complications varied between 0 (skin lesion excision, cataract surgery) and 75% (transrectal prostate biopsy). Whilst aspirin increased the rate of bleeding complications by factor 1.5 (median, interquartile range: 1.0-2.5), it did not lead to a higher level of the severity of bleeding complications (exception: intracranial surgery, and possibly transurethral prostatectomy). Surveys amongst doctors on the management of this problem demonstrate wide variations. Available guidelines are scarce and in part contradictory. CONCLUSIONS Only if low-dose aspirin may cause bleeding risks with increased mortality or sequels comparable with the observed cardiovascular risks after aspirin withdrawal, it should be discontinued prior to an intended operation or procedure. Controlled clinical studies are urgently needed.
