Abstract Introduction/Objective Direct oral anticoagulants (DOACs) have gained wide use in prevention and treatment of thromboembolic diseases. Although relatively rare with DOAC therapy, intracranial hemorrhage may become a medical emergency and needs to be managed with caution to avoid adverse consequences. Methods During the review of 94 patients with DOAC therapy related bleeding complications at William Beaumont hospital – Troy, Michigan, 3 patients were identified with intracranial hemorrhage. Information on DOAC therapy, the cause related to intracranial hemorrhage, and clinical assessment and management of these patients were collected from electronic medical charts with concurrent laboratory studies. Results There were 1 male and 2 female patients, ages 63, 67 and 86. Two patients were taking rivaroxaban 20 mg daily and 1 patient apixaban 5 mg bid for atrial fibrillation and DVT. Patients were clinically stable with no prior significant bleeding events, except for minor skin rashes. All patients experienced a minor trauma to the head and showed signs of brain injury. They were brought to the emergency department immediately. DOAC therapy was discontinued during the emergency evaluation. CT studies revealed 1 patient with subdural hematoma and 2 patients with focal intraparenchymal hemorrhage without mass effects. Both clinical and laboratory assessment revealed stable medical conditions. Patients received conservative care without surgical intervention and repeat CT studies demonstrated resolution of hemorrhage. One patient discontinued DOAC therapy permanently and the others resumed DOAC therapy with antidotes available. Clinical follow up showed no additional bleeding events. Conclusion Intracranial hemorrhage can occur in patients received DOAC therapy, even in clinically stable patients, and most likely happens after head injury. In this small group of patients, both clinical and laboratory evaluations showed stable medical conditions, with no need for surgery intervention. However, the decision of continuing DOAC therapy should be made with caution and it is reasonable to have antidote available for these patients.

Background: Fibrinogen (FIB) levels less than 150 mg/dL have been associated with increased rates of bleeding and lower survival in critically ill cirrhosis patients. Objective: We aimed to determine if treatment with cryoprecipitate (CRYO) for low FIB levels were associated with bleeding complications or survival. Patients / Methods: 237 cirrhosis patients admitted to an intensive care unit at a tertiary care liver transplant center with initial FIB levels less than 150 mg/dL were retrospectively assessed for CRYO transfusion, bleeding events, and survival outcomes. Results: The mean MELD score was 27.2 (95% CI 26.0 - 28.3) and CLIF-C Acute on Chronic Liver Failure (ACLF) score was 53.4 (51.9 - 54.8). Ninety-nine (41.8%) were admitted for acute bleeding and the remainder were admitted for non-bleeding illnesses. FIB level on admission correlated strongly with disease severity. After adjusting for disease severity, FIB on admission was not an independent predictor of 30-day survival (HR 0.99, 95% CI 0.99 - 1.01, p = 0.68). CRYO transfusion increased FIB levels but had no independent effect on mortality or bleeding complications (HR 1.10, 95% CI 0.72 - 1.70, p = 0.65). Conclusions: In cirrhosis patients with critical illness, low FIB levels on presentation reflect severity of illness but are not independently associated with 30-day mortality. Treatment of low FIB with CRYO also does not affect survival or bleeding complications suggesting FIB is an additional marker of severity of illness but is not itself a direct factor in the pathophysiology of bleeding in critically ill cirrhosis patients.

The Impact

Additional loading dose of acetylsalicylic acid (ASA) during percutaneous coronary interventions (PCIs) despite permanent oral ASA medication is frequently applicated. The impact on platelet reactivity and clinical events is not known. In this pilot study, we aimed to analyze high on-treatment platelet reactivity (HTPR) to aspirin in patients undergoing elective PCI. Platelet reactivity was measured using light-transmission aggregometry in 100 patients on permanent low-dose ASA medication undergoing elective PCI. Platelet reactivity measured by arachidonic acid-induced maximum of aggregation (MoA) in patients with versus without additional peri-procedural ASA loading (500 mg i.v.) was compared. HTPR was defined as MoA &#x3e;20% for ASA. Major adverse cerebro- and cardiovascular events (MACCEs) and bleeding events were evaluated during hospital course. HTPR rate was similar in both groups (HTPR to ASA: loading vs. control 6% vs. 16%, odds ratio [OR] = 0.33, 95% confidence interval [CI] 0.08–1.35, <i>p</i> = 0.12). In-hospital MACCEs were not different between groups (MACCE: loading vs. control: 0 vs. 0 patient, OR = 1.32, 95% CI 0.03–67.95, <i>p</i> = 0.89). Thrombolysis in myocardial infarction minimal bleedings were numerically higher in patients without ASA loading dose. In this pharmacodynamic pilot study, additional ASA loading did not reduce HTPR to ASA. Furthermore, ASA loading did not increase in-hospital MACCE and bleeding complications.

Introduction: Venous thromboembolism (VTE) is a common complication in multiple myeloma (MM) patients for several reasons; hematologic malignancy itself is a VTE risk factor and standard of care immunomodulatory drugs (IMiDs) in combination with dexamethasone (Dex) increase the risk further. This combination therapy has a mean VTE incidence of 21.5% in studies that did not use thromboprophylaxis and is recommended for all patients on IMiDs, although the optimal thromboprophylactic regimen remains uncertain. In clinical practice, aspirin (ASA) is commonly prescribed for VTE prophylaxis due to the ease of use. Despite this, the incidence of VTE remains between 7-14%. There is a growing body of literature supporting the efficacy and safety of direct oral anticoagulants (DOACs) for the treatment of VTE in cancer populations. We wanted to assess the incidence of VTE despite ASA prophylaxis at our institution and to further characterize the role of DOACs in the MM population. To do this, we performed a chart review of all MM patients who had been treated with lenalidomide and a DOAC, assessing for VTE development and patient outcomes. Methods: We conducted a retrospective chart review of patients with the diagnosis of MM treated with lenalidomide therapy at Fox Chase Cancer Center at Temple University Hospital or Cottman Avenue after Jan 1st, 2015 to July 2019. Eligible patients were identified through electronic medical record data mining for patients that had been diagnosed with MM, had been prescribed lenalidomide, had been taking ASA while on lenalidomide, and switched to rivaroxaban, edoxaban or apixaban. For comparison, the number of patients treated with lenalidomide and ASA who did not switch to a DOAC were also identified. Patient charts were reviewed for VTE development and bleeding complications after DOAC administration. Results: 132 patients were identified who had a diagnosis of MM and had been prescribed lenalidomide between Jan 1, 2015 and July 31, 2019. These patients were also prescribed aspirin except for three who were already on a DOAC prior to starting lenalidomide. Of the total 132 patients, only 17 were prescribed a DOAC. Six of the patients were on DOACs for reasons other than VTE (atrial fibrillation N=4, atrial flutter N=1, marantic endocarditis N=1). Eleven patients were started on DOACs for VTE; incidence of 8.3% in our myeloma population. However three of these VTEs occurred within one month of high dose melphalan chemotherapy and autologous stem cell rescue. These three patients had been off lenalidomide for over one month prior to VTE. Eight of the 17 patients with VTE developed clots in the setting of active MM and concurrent therapy with IMiD/Dex, independent of hospitalizations or other provoking factors. This is an incidence of 6.0% for VTE directly attributed to therapy. Six patients were on lenalidomide and Dex, while two patients developed VTE while on pomalidomide and Dex. No patients on lenalidomide experienced recurrent VTEs after being switched to therapeutic dose DOAC. One patient on pomalidomide/Dex did experience recurrent VTE. We examined all 17 patients who were on DOACs, 16 of which had been on IMiD and DOACs concurrently. Three had minor bleeding events which all resolved spontaneously. One patient had a major bleeding event, which was a fatal ruptured cerebral aneurysm while on a DOAC and ASA concurrently. Conclusion: The incidence of VTE in our patient population receiving IMiD/Dex while on ASA prophylaxis therapy was similar to what has been previously reported in the literature. We examined the clinical outcomes of 16 patients treated with IMiDs and DOACs concurrently and found few bleeding events. The one major bleed was likely precipitated by malignant hypertension and not a direct result of being on a DOAC. Taken together these results further support the growing body of evidence that DOACs are effective and safe treatments for VTE in cancer patients, including MM. Moving forward, our clinical experience with treatment dose DOACs supports the use of prophylactic dose DOACs to potentially further reduce the incidence of VTE in this high-risk population.

Background and purpose We aimed to determine the safety of intra-arterial Abciximab injection in the management of thromboembolic complications during endovascular treatment of ruptured cerebral aneurysms. Methods In a monocentric consecutive series of endovascular treatment of 783 ruptured aneurysms, 42 (5.3%) patients received Abciximab after the aneurysm was secured. Bleeding complications were registered and dichotomized as follows: new intracranial hemorrhage and peripheral bleeding. For each patient, World Federation of Neurosurgery (WFNS) subarachnoid hemorrhage (SAH) grade, shunting, and clinical outcomes in the post-operative period and at 3–6 months were recorded. Results SAH WFNS grades were as follows: grade I n = 14, grade II n = 10, grade III n = 11, grade IV n = 4, grade V n = 3. Ten patients had intracranial hematoma additionally to the SAH prior to embolization. Four patients (9.5%) presented more blood on the post-embolization CT but only one suffered a new clinically relevant intracranial hemorrhage. Two patients (4.8%) experienced significant peripheral bleeding but none were associated with long-term disabilities. Fourteen patients had a shunt installed less than 24 h prior to Abciximab injection and one less than 48 h later. At 3–6-month follow-up, 31 patients (74%) achieved a modified Rankin Scale score (mRS) of 2 or less, six patients (14%) had a mRS of 3–5, three were dead (7%), and two were lost at follow-up. Conclusion When the aneurysm is secured, intra-arterial Abciximab injection is a low complication rate treatment modality for thromboembolic events during embolization of cerebral ruptured aneurysm.

Background: A considerable proportion of elderly patients are known to have coexistent atrial fibrillation (AF) and amyloidosis. Both conditions increase stroke risk. Objective: We evaluated the best anticoagulation strategy in a series of AF patients with amyloidosis. Methods: Consecutive AF patients with coexistent amyloidosis undergoing catheter ablation at our center were included in the analysis. Based on the stroke-prophylaxis approach they were divided into 2 groups; group 1: left atrial appendage occlusion (LAAO) with Watchman and group 2: oral anticoagulation. Following LAAO, all patients remained on full dose non-vitamin K oral anticoagulants (NOAC) for 45 days. Transesophageal echocardiogram (TEE) was performed at 45 days to assess completeness of closure. If the occlusion was complete, patients were kept on aspirin, 81 mg/day for long-term. In case of leak or dense ‘smoke’ in the left atrium (LA) or enlarged LA, they were prescribed half-dose NOAC. NOACs included dabigatran, apixaban, endoxaban and rivaroxaban. Group 2 patients remained on full-dose NOAC during the whole study period (1 year). All patients were prospectively followed up for 1 year. Results: A total of 87 patients were included in the analysis; group 1: 56 and group 2: 31 . CHA 2 DS 2 -VASc score was comparable between the groups (gr. 1: 3.7±1.6 and gr. 2: 3.2±1.7, p=0.18). The most commonly used NOACs were apixaban (45, 51.7%) and rivaroxaban (34, 39%). After the 45-day TEE, 34 patients from group 1 remained on baby-aspirin and 22 on half-dose NOAC. Of the 22, 12 patients had leaks <5 mm, 6 had large LA (mean diameter 5.2±1.4 cm) and 4 patients had dense LA smoke. At 1-year follow-up, 3 stroke and 1 transient ischemic attack were reported in group 1 on baby-aspirin (4/34, 11.8%). No stroke or bleeding complications occurred in the 22 patients on half-dose NOAC. In group 2 patients on full-dose OAC, a total of 5 (5/31, 16.1%) bleeding events (1 subdural hematoma and 4 GI bleedings) were recorded. Additionally, a stroke was reported that happened during brief discontinuation of OAC for another medical procedure. Conclusion: In our series of patients with coexistent AF and amyloidosis, half-dose NOAC following LAA occlusion procedure was observed to be the safest stroke-prophylaxis strategy.

Introduction: Randomized trials have demonstrated the safety and efficacy of one month of dual antiplatelet therapy (DAPT) after placement of drug-eluting stents in patients with high bleeding risk. Patients with end-stage liver disease (ESLD) are underrepresented in these trials. Patients who undergo percutaneous coronary intervention (PCI) in preparation for orthotopic liver transplantation (OLT) exhibit a high incidence of bleeding complications on DAPT. The rates of bleeding versus thrombotic complications in ESLD patients placed on DAPT following PCI are poorly described. Methods: We retrospectively collected data from 61 patients who were evaluated for OLT between 2016 and 2019 and underwent PCI prior to listing. Bleeding events were classified using the Bleeding Academic Research Consortium (BARC) definitions and included if the following criteria were met: events occurred in the setting of DAPT, were non-procedural in etiology, and occurred during the time following PCI and prior to OLT. Ischemic complications were evaluated by the incidence of myocardial infarction (MI), stent thrombosis, in-stent restenosis (>50%) and all-cause mortality at 1 year follow-up. Results: A total of 55/61 patients (90%) were placed on DAPT following PCI. Among them, 21/55 patients (38%) bled while taking DAPT, including 15 patients (27%) with BARC types 3-5 first-time bleeding events and 10 patients (18%) requiring early discontinuation of therapy. The median time to first bleeding event was 8 days (range 1 to 477 days, 85 th percentile 17 days). Among ischemic complications, MI occurred in 11/55 patients (20%) however only one patient had a type 1 MI with the remaining being type 2 in etiology. There were no episodes of stent thrombosis and 2 episodes of in-stent restenosis during the 1 year follow-up. A total of 12/55 patients (22%) went on to receive OLT and 18/55 (33%) passed away by 1 year post-PCI. Conclusions: Patients with ESLD exhibit a high rate of clinically significant bleeding on DAPT when compared to overall thrombotic events. The majority of bleeds occurred within the first month after PCI. These findings illustrate the need for larger studies to assess the safety of single instead of dual antiplatelet therapy in patients with ESLD who receive PCI.

VEGF(R)-targeted therapies are associated with an increased risk of thromboembolism and bleeding, which might be pronounced in patients with increased cardiovascular risk. Nevertheless, sorafenib represents an important treatment option in patients with hepatocellular carcinoma (HCC). We retrospectively investigated the risk of arterial/venous thromboembolic and bleeding events in 252 patients treated with sorafenib for HCC between 05/2006 and 03/2020 at the Medical University of Vienna. Cardiovascular risk was assessed using Framingham score. Eight patients (3.2%) experienced 11 arterial/venous thromboembolic events. Only two patients (0.8%) developed arterial thromboembolism even though cardiovascular risk was low, intermediate, and high in 15 (8.7%), 104 (60%), and 54 (31.2%) of 173 assessable patients. Median overall survival (OS) was shorter in the high risk vs. low/intermediate risk group 7.4 (95% CI: 3.4–11.3) vs. 10.0 (95% CI: 6.8–13.2 months) and independently associated with OS in multivariable analysis HR: 1.53 (95% CI: 1.07–2.19; p = 0.019). Forty-eight (19%) patients experienced a bleeding, most commonly gastrointestinal bleeding (14%) followed by epistaxis (4.7%). Advanced liver dysfunction was not associated with an increased incidence of bleeding/venous thromboembolism. Sorafenib represents a safe treatment option even in patients with increased cardiovascular risk. Bleeding complications were comparable with previous reports, even though patients with more advanced liver disease were included.

The incidence of venous thromboembolism (VTE) in peritoneal malignancies can approach 30 to 50 per cent without prophylaxis. Prophylaxis in cytoreductive surgeries (CRS) presents a challenge to preoperative heparin-based therapy because of an increased risk of coagulopathy and potential for bleeding. Herein, we report the large series of CRS and hyperthermic intraperitoneal chemotherapy receiving dextran-40 prophylaxis. Retrospective chart review of peritoneal malignancies patients undergoing CRS at University of Nebraska Medical Center identified 69 individuals who received dextran-40 between 2010 and 2013. The incidences of VTEs, perioperative bleeding, complications, morbidity, and mortality were determined in-hospital and at 90 days. Of the 69 patients treated, the 30-day VTE rate was 8.7 per cent, and no pulmonary embolisms, bleeding, anaphylactoid reaction, or mortality were observed with dextran usage. The specific VTE events included three upper extremity and three lower extremity VTEs. No additional VTE events were identified between 30 and 90 days. In conclusion, dextran-40 prophylaxis was not associated with any perioperative bleeding events, and the observed incidence of VTE was comparable to reported heparin-based prophylaxis in CRS/hyperthermic intraperitoneal chemotherapy patients. This data supports further exploration of dextran-40 as a VTE prophylactic agent in complex surgical oncology cases.

Purpose: Use of anticoagulation in patients on ECMO, especially in Chinese, has always been difficult. This study aimed to review the incidence of bleeding, thrombosis, and transfusion requirement in Chinese ECMO patients and to identify risk factors for bleeding complications. Materials and Methods: This was a retrospective observational study of a tertiary hospital from 2010 to 2018. Patients aged ⩾18 years who received ECMO were included. The primary outcome was incidence of bleeding. Secondary outcomes included ICU mortality, hospital mortality, and length of the ICU and hospital stay. Results: Of the 130 patients, 55(42.3%) had at least one bleeding events and thrombosis occurred in 37(28.5%). A lower fibrinogen level (adjusted OR 0.56 (0.36–0.86), p = 0.009), bloodstream infection (adjusted OR 2.76 (1.01–7.53), p = 0.047) and longer duration on ECMO (adjusted OR 1.14 (1.02–1.27), p = 0.018) were independently associated with occurrence of bleeding. APTT (adjusted OR 0.99 (0.97–1.01), p = 0.370) and platelet count (adjusted OR 1.00 (0.98–1.01), p = 0.632) were not statistically significant risk factors for bleeding events. Conclusions: Bleeding and thrombosis were common complications in Chinese patients receiving ECMO. Hypofibrinogenemia and bloodstream infection, but not APTT nor platelet counts, were independent risk factors for bleeding events.

Abstract Background Reducing the incidence of venous thromboembolism (VTE) following abdominal body contouring surgery remains a top priority for patient safety. There is a lack of consensus regarding the optimal chemoprophylactic agent for postoperative VTE prophylaxis, and the role of oral anticoagulants warrants further investigation. Objectives The aim of this multisurgeon, single-institution study was to determine the safety and efficacy of a 7-day postoperative rivaroxaban regimen for VTE prophylaxis in abdominal body contouring surgery. Methods A retrospective chart review was performed of all patients who underwent abdominoplasty, circumferential body lift, fleur-de-lis panniculectomy, or circumferential fleur-de-lis panniculectomy at our surgical center from August 2014 to November 2019. A 7-day postoperative course of once-daily 10 mg rivaroxaban, starting on postoperative day 1, was administered to every patient unless there was a contraindication. The 2 primary endpoints were the incidence of VTE and bleeding events. Results A total of 600 patients were included in the study. There were no deaths. There were 4 (0.7%) incidents of VTE events: 2 (0.3%) patients suffered pulmonary embolus and 2 (0.3%) patients suffered a lower-extremity deep venous thrombosis. A total of 13 (2.2%) patients suffered complications related to bleeding. Of these, operative intervention for control and evacuation was required in 7 (1.2%) patients. Conclusions A 7-day postoperative course of once-daily rivaroxaban for VTE risk reduction in abdominal body contouring surgery is associated with a low incidence of VTE events and a low risk of bleeding complications. Level of Evidence: 4
