This CIRSE Standards of Practice document is aimed at interventional radiologists and provides best practices for performing transarterial chemoembolisation. It has been developed by an expert writing group under the guidance of the CIRSE Standards of Practice Committee. It will encompass all technical details reflecting European practice of different TACE procedures (Lp-TACE, DEM-TACE, DSM-TACE, b-TACE) as well as revising the existing literature on the various clinical indications (HCC, mCRC, ICC, NET). Finally, new frontiers of development will also be discussed.

This study explored factors that can predict effectiveness outcomes after transarterial radioembolization in colorectal liver metastases in the liver. In a cohort of 237 patients, among other factors, we found that an Aspartate transaminase to Platelet Ratio Index (APRI) value of > 0.40 was a particularly strong independent predictor of worse overall survival, progression-free survival and hepatic progression-free survival outcomes. Background: Transarterial radioembolisation (TARE) with Yttrium-90 resin microspheres is a treatment option for patients with metastatic colorectal cancer in the liver (mCRC). A better understanding of the prognostic factors and treat-ment application can improve survival outcomes. Methods: We analysed the safety and effectiveness of 237 mCRC patients included in the prospective observational study CIRSE Registry for SIR-Spheres Therapy (CIRT) for indepen-dent prognostic factors for overall survival (OS), progression-free survival (PFS) and hepatic progression-free survival (hPFS) using the Cox proportional-hazard model. Results: The median OS was 9.8 months, median PFS was 3.4 months and median hPFS was 4.2 months. Independent prognostic factors for an improved overall survival were the absence of extra-hepatic disease ( P = .0391), prior locoregional procedures ( P = .0037), an Aspartate transaminase to Platelet Ratio Index (APRI) value of 0.40 ( P = .0416) and prior ablation ( P = .0323), and for hPFS these were 2 to 5 tumor nodules ( P = .0148), Albumin-bilirubin (ALBI) grade 3 ( P = .0075) and APRI > 0.40 ( P = .0207). During the study, 95 of 237 (40.1%) patients experienced 197 adverse events, with 28 of 237 (11.8%) patients having a grade 3 or higher adverse events. Conclusion: Including easy-to-acquire laboratory markers INR, APRI, ALBI and using partition model dosimetry can identify mCRC patients that may benefit from TARE.

CIREL, a prospective, Europe-wide, observational study aimed to assess the real-world feasibility and tolerability of irinotecan-based transarterial chemoembolization (LP-irinotecan TACE) for unresectable colorectal cancer liver metastases with regard to the treatment plan and adverse events (AEs). CIREL enrolled 152 eligible patients (≥18 years) with liver-only or dominant metastases treated with LP-irinotecan TACE following a multidisciplinary tumor board decision. Data were prospectively collected for baseline, the number of planned and performed sessions, and technical information and safety according to CTCAE 4.03/5.0. Results from 351 analyzed treatment sessions showed technical success for 99% of sessions, and 121 patients (79%) completed all planned sessions. Further, 60% of sessions were performed using opioids, 4% intra-arterial anesthetics, and 25% both. Additionally, 60% of patients experienced at least one peri-interventional AE of any grade; 8% of grade 3–4. Occurrence of AEs was related to larger liver-involvement (p < 0.001), bi-lobar disease (p = 0.002), and larger beads (p < 0.001). Using corticosteroids together with antiemetics showed reduced and lower grade vomiting (p = 0.01). LP-irinotecan TACE was tolerated well and had a high proportion of completed treatment plans. This minimally invasive locoregional treatment can be used together with concomitant systemic therapy or ablation.

In the last 20 years, the treatment of abdominal aortic aneurysms has essentially evolved from surgical to minimally invasive endovascular treatment.There are still a number of clinical situations that make surgical intervention useful or even necessary. This underlines the importance of interdisciplinary vascular centers for the treatment of complex aortic pathologies and their sequelae.In the following article, the arguments for the choice of procedure for the treatment of infrarenal aortic aneurysms are discussed and the recommendations of various guidelines are compared.KLINISCHES/METHODISCHES PROBLEM: In den letzten 20 Jahren hat sich die Behandlung des abdominellen Aortenaneurysmas (AAA) im Wesentlichen fort von der operativen hin zur minimal-invasiven endovaskulären Therapie entwickelt.Es gibt jedoch nach wie vor eine Reihe von klinischen Situationen, die einen operativen Eingriff sinnvoll erscheinen lassen oder sogar notwendig machen. Dies unterstreicht die Bedeutung interdisziplinärer, vaskulärer Zentren für die Behandlung komplexer Aortenpathologien und ihrer Folgeerscheinungen. EMPFEHLUNG FüR DIE PRAXIS: Im folgenden Artikel werden die Argumente für die Verfahrenswahl zur Versorgung infrarenaler Aortenaneurysmen diskutiert und die Empfehlungen verschiedener Leitlinien vergleichend gegenübergestellt.

Since the first version of the S3 guideline for the diagnosis and treatment of hepatocellular carcinoma (HCC) in 2013, a large number of studies have consolidated the data on transarterial radioembolization (TARE) and created a broad evidence base. As a result, TARE was incorporated into the current 2021 S3 guideline with a number of specific recommendations, whereas it was previously only offered under study conditions. TARE is now offered with the other minimally invasive procedures for bridging and downstaging before liver transplantation, but also as an alternative to transarterial chemotherapy (TACE) in intermediate HCC and in locally limited intrahepatic cholangiocarcinoma in second-line therapy for selected patients-albeit with different levels of evidence. Based on the study situation, however, TARE is not recommended for advanced HCC; here, systemic therapy with immunotherapeutic agents is preferred based on current data.Seit der ersten Fassung der S3-Leitlinie zur Diagnostik und Therapie des hepatozellulären Karzinoms im Jahr 2013 hat eine Vielzahl von Studien die Datenlage zur transarteriellen Radioembolisation (TARE) konsolidiert und eine breite Evidenzbasis geschaffen. Dies führt dazu, dass die TARE mit einer Reihe von konkreten Empfehlungen in die aktuelle S3-Leitlinie von 2021 eingegangen ist, während sie bisher nur unter Studienbedingungen angeboten werden sollte. So wird die TARE nun mit den anderen minimal-invasiven Verfahren zum Bridging und Downstaging vor Lebertransplantation, aber auch als Alternative zur transarteriellen Chemotherapie (TACE) beim intermediären hepatozellulären Karzinom (HCC) und beim lokal begrenzten intrahepatischen Cholangiokarzinom (iCCA) in der Zweitlinientherapie für selektierte Patienten angeboten – wenn auch mit unterschiedlichen Evidenzleveln. Aufgrund der Studienlage wird die TARE jedoch nicht für das fortgeschrittene HCC empfohlen; hier wird aufgrund der aktuellen Datenlage der systemischen Therapie mit Immuntherapeutika der Vorzug gegeben.

The updated German S3 guideline "Diagnostics and therapy of hepatocellular carcinoma and biliary carcinomas" covers two tumor entities. The original guideline published in 2013 focusing only on the diagnosis and therapy of hepatocellular carcinoma (HCC) has been expanded to include intrahepatic cholangiocarcinoma. These guidelines were developed within the framework of the guideline program on oncology of the Scientific Medical Society e. V. (AWMF), the German Cancer Society (DKG) and German Cancer Aid Society (DKG) under the auspices of the German Society for Digestive and Metabolic Diseases (DGVS). In addition to updated recommendations regarding histopathology, radiological diagnostics and treatments, the main innovations of the revised guidelines on HCC include a complete revision of the section on the systemic therapeutic approach in advanced stages of the disease. This article presents the significance of the current recommendations for diagnostic and interventional radiology in comparison to other national and international guidelines and should serve to improve the quality of patient care through more widespread dissemination.Die aktualisierte deutsche S3-Leitlinie „Diagnostik und Therapie des hepatozellulären Karzinoms und biliärer Karzinome“ umfasst zwei Tumorentitäten. Bisher bestand nur eine Leitlinie zur Diagnostik und Therapie des hepatozellulären Karzinoms (HCC) aus dem Jahr 2013, wobei die Leitlinie zum Cholangiokarzinom (CC) jetzt zum ersten Mal bearbeitet wurde. Diese Leitlinien entstanden im Rahmen des Leitlinienprogramms Onkologie der Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V. (AWMF), der Deutschen Krebsgesellschaft e. V. (DKG) und Deutschen Krebshilfe unter Federführung der Deutschen Gesellschaft für Verdauungs- und Stoffwechselkrankheiten (DGVS). Die wesentlichen Neuerungen der überarbeiteten Leitlinien zum HCC umfassen neben aktualisierten Empfehlungen hinsichtlich Histopathologie, radiologischer Diagnostik und Therapien vor allem eine komplette Überarbeitung des Abschnitts zum systemtherapeutischen Vorgehen bei fortgeschrittenem Stadium der Erkrankung. Der vorliegende Artikel stellt die Bedeutung der aktuellen Empfehlungen für die diagnostische und interventionelle Radiologie im Vergleich zu anderen nationalen und internationalen Leitlinien dar und soll durch eine flächendeckendere Verbreitung der Qualitätssteigerung bei der Patientenversorgung dienen.

Purpose Radioembolization has emerged as a treatment modality for patients with primary and secondary liver tumours. This observational study CIRT-FR (CIRSE Registry for SIR-Spheres Therapy in France) aims to evaluate real-life clinical practice on all patients treated with transarterial radioembolization (TARE) using SIR-Spheres yttrium-90 resin microspheres in France. In this interim analysis, safety and quality of life data are presented. Final results of the study, including secondary effectiveness outcomes, will be published later. Overall, CIRT-FR is aiming to support French authorities in the decision making on reimbursement considerations for this treatment. Methods Data on patients enrolled in CIRT-FR from August 2017 to October 2019 were analysed. The interim analysis describes clinical practice, baseline characteristics, safety (adverse events according to CTCTAE 4.03) and quality of life (according to EORTC QLQ C30 and HCC module) aspects after TARE. Results This cohort included 200 patients with hepatocellular carcinoma (114), metastatic colorectal cancer (mCRC; 38) and intrahepatic cholangiocarcinoma (33) amongst others (15). TARE was predominantly assigned as a palliative treatment (79%). 12% of patients experienced at least one adverse event in the 30 days following treatment; 30-day mortality was 1%. Overall, global health score remained stable between baseline (66.7%), treatment (62.5%) and the first follow-up (66.7%). Conclusion This interim analysis demonstrates that data regarding safety and quality of life generated by randomised-controlled trials is reflected when assessing the real-world application of TARE. Trial Registration Clinical Trials.gov NCT03256994.

To evaluate pharmacokinetic and safety profile of LifePearl microspheres loaded with irinotecan (LifePearl-IRI) in the treatment of liver-dominant, metastatic colorectal carcinoma (LM-CRC) by transarterial chemoembolization. In a prospective, multicentre pharmacokinetic study, 14 patients with LM-CRC progressing on at least one line of chemotherapy were treated with LifePearl-IRI. Six patients received unilobar treatment, treating one lobe per session with 100 mg of irinotecan every 2 weeks. Eight patients received bilobar treatment, treating two lobes per session with 100 mg of irinotecan each (200 mg in total), every 4 weeks. At 24 h, near complete plasma clearance occurred for both irinotecan and SN-38, regardless of the dose. Mean plasma C(max(100 mg))was 254.50 +/- 104.17 ng/mL for irinotecan and 46.72 +/- 13.75 ng/mL for SN-38. Mean C(max(200 mg))was 970.09 +/- 353.75 ng/mL for irinotecan and 118.45 +/- 25.11 ng/mL for SN-38. Significantly higher Cmax-iri((200 mg))than Cmax-iri((100 mg))supported rate-limiting irinotecan-to-SN-38 conversion. Adverse events during the first 30 days upon initial treatment were hypertension in 21.4%, abdominal pain in 14.3%, and increased transaminases and fever in 7.1% of patients. Four serious adverse events were noted: respiratory failure, constipation, necrotizing pancreatitis, and ischaemic cholecystitis. Chemoembolization with LifePearl-IRI is technically feasible and relatively well tolerated, with a good pharmacokinetic profile and minimal systemic exposure of both irinotecan and SN-38, after both unilobar and bilobar treatment with 100 or 200 mg, respectively.

Interventional oncology (IO) has proven to be highly efficient in the local therapy of numerous malignant tumors in addition to surgery, chemotherapy, and radiotherapy. Due to the advent of immune-oncology with the possibility of tumor control at the molecular and cellular levels, a system change is currently emerging. This will significantly rule oncology in the coming decades. Therefore, one cannot think about IO in the 21st century without considering immunology. For IO, this means paying much more attention to the immunomodulatory effects of the interventional techniques, which have so far been neglected, and to explore the synergistic possibilities with immuno-oncology. It can be expected that the combined use of IO and immuno-oncology will help to overcome the limitations of the latter, such as limited local effects and a high rate of side-effects. To do this, however, sectoral boundaries must be removed and interdisciplinary research efforts must be strengthened. In case of success, IO will face an exciting future.

BACKGROUND: About 70-80% of patients with colorectal liver metastases appear as ineligible for a curative treatment approach. Transarterial chemoembolisation (TACE) using irinotecan-eluting beads has emerged as a promising treatment option in cases with irresectable liver metastases. Despite being in clinical practice for years, little is known about the treatment characteristics and outcomes when used as per routine hospital practice. METHODS: Patients with hepatic metastases from colorectal cancer origin, admitted to contributing centres to receive TACE with drug-eluting LifePearl® Microspheres loaded with irinotecan, as part of their standard care, will be consecutively added to the registry. Data will be collected until the end of study, loss to follow-up or death. Primary endpoint is the characterisation of the treatment usage at the selected sites in Europe. Secondary endpoints include outcome parameters, safety and toxicity, as well as quality of life. CONCLUSION AND AIMS: This multicentre, international, prospective observational study conducted in European centres plans to collect real-life data. This data will form an evidence-base from which conclusions can be drawn on how to improve patient selection and optimise treatment protocols when treating with TACE using irinotecan-eluting microspheres.

Purpose Transarterial chemoembolisation (TACE) using irinotecan-eluting beads is an additional treatment option for colorectal cancer liver metastases (CRLM) patients that are not eligible for curative treatment approaches. This interim analysis focuses on feasibility of the planned statistical analysis regarding data distribution and completeness, treatment intention, safety and health-related quality of life (HRQOL) of the first 50 patients prospectively enrolled in the CIrse REgistry for LifePearl™ microspheres (CIREL), an observational multicentre study conducted across Europe. Methods In total, 50 patients ≥ 18 years diagnosed with CRLM and decided to be treated with irinotecan-eluting LifePearl™ microspheres TACE (LP-irinotecan TACE) by a multidisciplinary tumour board. There were no further inclusion or exclusion criteria. The primary endpoint is the categorisation of treatment intention, and secondary endpoints presented in this interim analysis are safety, treatment considerations and HRQOL. Results LP-irinotecan TACE was conducted in 42% of patients as salvage therapy, 20% as an intensification treatment, 16% as a first-line treatment, 14% a consolidation treatment and 8% combination treatment with ablation with curative intent. Grade 3 and 4 adverse events were reported by 4% of patients during procedure and by 10% within 30 days. While 38% reported a worse, 62% reported a stable or better global health score, and 54% of patients with worse global health score were treated as salvage therapy patients. Conclusion This interim analysis confirms in a prospective analysis the feasibility of the study, with an acceptable toxicity profile. More patients reported a stable or improved HRQOL than deterioration. Deterioration of HRQOL was seen especially in salvage therapy patients. Trial Registration NCT03086096.

ZusammenfassungIn der Abklärung von hepatozellulären Karzinomen (HCCs) bei Hochrisikopatienten wurde zur standardisierten Befundung und Dokumentation der Kontrastmittel-Computertomografie (CECT) und Kontrastmittel-Magnetresonanztomografie (CEMRT) vor wenigen Jahren das „Liver Imaging Reporting and Data System” (LI-RADS) durch das American College of Radiology (ACR) erstellt. Die LI-RADS-Kategorisierung wird zur Klassifikation von Leberläsionen in der Leberzirrhose als sicher benigne (LR-1), intermediär (LR2 – 4) bis zu „definitiv HCC“ (LR-5) beurteilt. Seit 2014 wurde die LI-RADS-Klassifikation durch eine Arbeitsgruppe von internationalen Radiologen und Hepatologen auf die Kontrastmittelsonografie erweitert. Zeitgleich mit der Zulassung des Kontrastmittels SonoVue™ (in den USA Lumason™) wurde die Klassifikation 2016 in die LI-RADS Kategorisierung integriert und wird in diesem Artikel erläutert (CEUS-LI-RADS).

Purpose The MIRACLE I pilot study was designed as a preliminary investigation of safety and efficacy of Embozene TANDEM microspheres loaded with doxorubicin for treatment of locally untreatable (i.e., unresectable and not suitable for local thermal ablation) hepatocellular carcinoma (HCC).

International audience; Comparison of Stereotactic Body Radiation Therapy and Radiofrequency Ablation in the Treatment of Intrahepatic Metastases” by Jackson et al is a thought-provoking addition to the literature concerning treatment of colorectal cancer metastasis (CLM). The benefits of hepatic CLM resection are well established; however, most patients are not candidates for resection. Local tumor ablation is a safe and effective alternative treatment for select patients. Considerable research has evaluated percutaneous ablation as treatment of CLM, including retrospective reviews with long-term follow-up and prospective randomized trials showing prolongation of progression-free and patient survival compared with chemotherapy alone.1, 2, 3 The National Comprehensive Cancer Network guidelines recommend ablation for patients with CLMs with or without surgery as long as all tumors can be effectively treated. Conversely, the evidence for stereotactic body radiation therapy (SBRT) in the treatment of any size of CLM is sparse; the National Comprehensive Cancer Network recommends that SBRT not be used indiscriminately when other treatment options are available.

308 Background: Trans-arterial radioembolization (TARE) is a treatment option for patients with intrahepatic cholangiocarcinoma (ICC). The CIRSE Registry for SIR-Spheres Therapy (CIRT) is the first European prospective multi-centre observational study designed to evaluate the clinical outcomes of patients treated with TARE with SIR-Spheres Y90 resin microspheres for ICC in the multi-institutional real-life clinical setting. The study was conducted by the Cardiovascular and Interventional Radiological Society of Europe (CIRSE). Methods: Patients were enrolled prospectively between Jan 2015 and 31 Dec 2017. Eligible patients were adults treated with TARE with Y90 resin microspheres for ICC. Data on baseline characteristics and treatment intention/clinical context and dosimetry were collected, as well as follow-up data (every 3 months; for 24 months after treatment), including overall survival (OS), (hepatic) progression-free survival [(h)PFS], safety and Global Health Status (GHS, using the European Organisation for the Research and Treatment of Cancer QLQ-C30). Results: 120 patients were included from 18 sites in 8 European countries. Median age was 63 years (range: 29-86) and 54.2% were male. Median tumour to liver percentage was 12.8%. Median prescribed activity was 1.32 GBq for whole liver treatments (n = 49), 1.20 GBq for right lobe treatments (n = 56) and 0.82 GBq for left lobe treatments (n = 51). 97.5% of the delivered activity was within 90% of the prescribed activity. TARE treatment as a first line (L1) global strategy was applied in 39.1%, 27.4% as second line (after systemic therapy). Treatment intention was predominantly palliative (69.2%) or tumour shrinkage (20.8%). Median OS was 14.7 months (95% confidence interval (CI) 10.9 – 17.9). Median PFS was 5.7 months (95% CI 3.9 – 7.5), whereas hPFS was 6.2 months (95% CI 4.1 – 8.5). Mean GHS was 59.3 at baseline, 61.0 after 3 months, 56.0 at 6 months, 54.4 at 9 months and 63.0 after 1 year. Severe adverse events (grade 3 and 4) were found in 13 (10.8%) patients: (abdominal pain 3.3%, fatigue 1.7%, gastrointestinal ulceration 0.8%, gastritis 0.8%, radiation cholecystitis 0.8%, radiation-induced liver disease 1.7%, other 5.8%). Detailed subgroup analyses are currently being performed. Updated data describing OS, PFS and hPFS for L1 TARE vs TARE after systemic chemotherapy, as well as prognostic factors for OS, PFS and hPFS will be shown. Conclusions: The results from this large prospective multi-centre observational study shows that in the real-world context, TARE is applied early and successfully in the treatment pathway. TARE is shown to be an effective and safe treatment with no meaningful deterioration of quality of life. Clinical trial information: NCT02305459.

The updated German S3 guidelines "Colorectal Carcinoma" were created as part of the oncology program of the Association of the Scientific Medical Societies (AWMF), German Cancer Society and the German Cancer Aid under the auspices of the German Society for Digestive and Metabolic Disorders (DGVS) and they replace the previous guidelines from 2013. The main changes in the updated guidelines include the latest recommendations regarding endoscopy and adjuvant/neoadjuvant therapies as well as a complete restructuring of the section regarding therapeutic approach in metastases and in the palliative situation.

The American College of Radiology (ACR) endorsed the Liver Imaging Reporting and Data System (LI-RADS) for standardized reporting and data collection of computed tomography (CT) and magnetic resonance (MR) imaging for hepatocellular carcinoma (HCC) in high-risk patients (liver cirrhosis). The LI-RADS imaging criteria are used to classify 'observations' from 'definitely benign' (LR-1) to 'definitely HCC' (LR-5) based on imaging criteria.Coincidently, the recent approval in the United States of a microbubble contrast agent for liver imaging (LumasonIn der Abklärung von hepatozellulären Karzinomen (HCCs) bei Hochrisikopatienten wurde zur standardisierten Befundung und Dokumentation der Kontrastmittel-Computertomografie (CECT) und Kontrastmittel-Magnetresonanztomografie (CEMRT) vor wenigen Jahren das „Liver Imaging Reporting and Data System” (LI-RADS) durch das American College of Radiology (ACR) erstellt.

The primary tumor side is emerging as a prognostic factor for patients with liver metastatic colorectal cancer (mCRC). In a combined analysis of data from 2 randomized studies, the addition of selective internal radiation therapy to first-line chemotherapy in patients with mCRC was associated with statistically and clinically significant overall survival gains for patients with a right-sided primary tumor. Background: The primary tumor side is emerging as a major prognostic factor for patients with metastatic colorectal cancer (mCRC). We examined the survival data from 2 randomized studies to determine whether the outcomes differ between patients with mCRC with right-sided primary (RSP) tumors and those with left-sided primary (LSP) tumors after selective internal radiation therapy (SIRT) plus mFOLFOX6 (folinic acid [leucovorin], 5-fluorouracil, oxaliplatin) chemotherapy, versus chemotherapy alone. Patients and Methods: Separate and combined analyses were performed on the data from the SIRFLOX and FOXFIRE global trials, which compared chemotherapy plus SIRT with chemotherapy alone for patients with mCRC liver metastases. The primary tumor side data were prospectively collected. The principal outcome measure was overall survival (OS) stratified by treatment and primary tumor side. Results: In the combined analysis of all 739 patients enrolled, SIRT had no effect on OS (median OS, 24.3 vs. 24.6 months; hazard ratio [HR], 1.021; P = .810). For the 179 patients (24.2%) with a RSP tumor, OS was improved with the addition of SIRT (median, 22.0 vs. 17.1 months HR, 0.641; P = .008). The addition of SIRT was not associated with a significant difference in OS among the 540 patients with a LSP tumor (median, 24.6 vs. 26.6 months; HR, 1.120; P = .264). A test of treatment interaction by primary tumor side was statistically significant for RSP and SIRT (P = .002). Conclusion: The addition of SIRT for patients with RSP tumors, but not for those with LSP tumors, was associated with a statistically and clinically significant OS gain. (C) 2018 Elsevier Inc.

We report on the course of disease in a young woman, originally admitted with suspected refractory infectious tropical traveler's diarrhea. However, symptoms did not resolve upon either symptomatic or subsequent antibiotic therapy. When neurologic deterioration was observed, imaging studies revealed a dramatic series of thromboembolic events, including intracranial hemorrhage caused by extensive sinus vein thrombosis as well as thrombi of the right cardiac ventricle. Colonic mucosal biopsy samples finally led to the histologic diagnosis of ulcerative colitis. Having excluded thrombophilia or any other disease potentially related to a prothrombotic state, we interpreted the thromboembolic events as secondary to the primary manifestation of the underlying inflammatory bowel disease. The increased risk of thromboembolic complications—especially deep vein thrombosis and pulmonary embolism—in inflammatory bowel disease is well documented in the literature. However, sinus vein thrombosis and cardiac thrombi represent a remarkable dimension of this risk and a rare course of coagulopathy secondary to an acute flare of ulcerative colitis. Still, there is a lack of awareness of this risk, resulting in poor implementation of preventive measures modifying risk factors and allowing for pharmacological prophylaxis. We therefore emphasize that—in line with the 2014 German S3 Guideline—thromboprophylaxis in the setting of an acute flare of inflammatory bowel disease is mandatory and should not be restricted because of safety concerns.
