Catheter directed thrombolysis and mechanical intervention in deep venous thrombosis: What is the status after the ATTRACT Trial?

Postgrad Med 2021 Apr 16. Epub 2021 Apr 16.

Division of Interventional Radiology, Department of Radiological Sciences, David Geffen School of Medicine at UCLA, Los Angeles, California.

Deep venous thrombosis (DVT) is a major cause of acute and chronic morbidity, mortality, and increased healthcare costs. Endovascular methods of thrombus removal and re-establishing venous patency are increasing in both scope and usage. The most commonly used method of endovascular thrombectomy is catheter directed thrombolysis (CDT). Read More

Thrombolytic therapy for pulmonary embolism.

Cochrane Database Syst Rev 2021 Apr 15;4:CD004437. Epub 2021 Apr 15.

The Center of Gerontology and Geriatrics, West China Hospital, Sichuan University, Chengdu, China.

Background: Thrombolytic therapy is usually reserved for people with clinically serious or massive pulmonary embolism (PE). Evidence suggests that thrombolytic agents may dissolve blood clots more rapidly than heparin and may reduce the death rate associated with PE. However, there are still concerns about the possible risk of adverse effects of thrombolytic therapy, such as major or minor haemorrhage. Read More

Histological Assessment of Lower Extremity Deep Vein Thrombi from Patients Undergoing Percutaneous Mechanical Thrombectomy.

J Vasc Surg Venous Lymphat Disord 2021 Apr 6. Epub 2021 Apr 6.

Division of Vascular Surgery, Department of Surgery, NYU Langone Health, New York, NY 10016, USA. Electronic address:

Background: Histological analyses of deep vein thrombi (DVT) are based on autopsy samples and animal models.

Challenges and Advances in Managing Thrombocytopenic Cancer Patients.

J Clin Med 2021 Mar 11;10(6). Epub 2021 Mar 11.

Institute of Hematology, Davidoff Cancer Center, Rabin Medical Center, Petah Tikva 4941492, Israel.

Cancer patients have varying incidence, depth and duration of thrombocytopenia. The mainstay of managing severe chemotherapy-induced thrombocytopenia (CIT) in cancer is the use of platelet transfusions. While prophylactic platelet transfusions reduce the bleeding rate, multiple unmet needs remain, such as high residual rates of bleeding, and anticancer treatment dose reductions/delays. Read More

Paget-Schroetter Syndrome in a Young Female.

J Investig Med High Impact Case Rep 2021 Jan-Dec;9:23247096211003263

Ashland Bellefonte Cancer Center, Ashland, KY, USA.

Paget-Schroetter syndrome or effort thrombosis is a relatively rare primary spontaneous thrombosis of upper extremity deep veins secondary to entrapment of axillary subclavian veins from an abnormality of the thoracic outlet. It is commonly seen in young adults who lift heavy weights or strenuous use of the upper extremities during athletic activities. Repetitive microtrauma to the subclavian vein secondary to narrow costoclavicular space and strenuous activities leads to intimal layer inflammation, hypertrophy, fibrosis, and coagulation cascade activation.

Glomerulonephritis in AKI: From Pathogenesis to Therapeutic Intervention.

Front Med (Lausanne) 2020 2;7:582272. Epub 2021 Mar 2.

Nephrology, Dialysis and Transplantation Unit, Department of Emergency and Organ Transplantation, University of Bari, Bari, Italy.

Acute kidney injury (AKI) is increasingly emerging as a global emergency. Sepsis, major surgery, and nephrotoxic drugs are the main causes of AKI in hospitalized patients. However, glomerulonephritis accounts for about 10% of AKI episodes in adults, mainly related to rapidly progressive glomerulonephritis resulting from granulomatous polyangiitis (GPA, Wegener granulomatosis), microscopic polyangiitis (MPA), and anti-glomerular basement membrane (GBM) disease.

Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography Imaging Predicts Vein Wall Scarring and Statin Benefit in Murine Venous Thrombosis.

Circ Cardiovasc Imaging 2021 Mar 16:CIRCIMAGING120011898. Epub 2021 Mar 16.

Cardiology Division, Cardiovascular Research Center, Massachusetts General Hospital, Harvard Medical School, Boston, MA (C.W.K., G.Q., F.A.J.).

Background: The postthrombotic syndrome is a common, often morbid sequela of venous thrombosis (VT) that arises from thrombus persistence and inflammatory scarring of juxtaposed vein walls and valves. Noninvasive F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) imaging can measure neutrophil inflammation in VT. Here, we hypothesized (1) early fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) VT inflammation can predict subsequent vein wall scarring (VWS) and (2) statin therapy can reduce FDG-PET VT inflammation and subsequent VWS.

The risk of thrombosis after acute-COVID-19 infection.

QJM 2021 Mar 15. Epub 2021 Mar 15.

Department of Specialistic Medicine, Division of Cardiology, Santa Maria della Misericordia Hospital, Rovigo, Italy.

Severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) has been associated with coagulation dysfunction which predisposes patients to an increased risk of both venous and arterial thromboembolism, increasing the short-term morbidity and mortality. Current data evidenced that the rate of post discharge thrombotic events in COVID-19 patients is lower compared to that observed during hospitalization. Rather than "true thrombotic events", these complications seem more probably "immunothrombosis" consequent to the recent infection. Read More

Activated Prothrombin Complex Concentrate-Induced Atypical Hemolytic Uremic Syndrome Treated with Eculizumab.

Am J Case Rep 2021 Mar 8;22:e929616. Epub 2021 Mar 8.

Department of Hematology and Oncology, Veterans Affairs Loma Linda Healthcare System, Loma Linda, CA, USA.

BACKGROUND Atypical hemolytic uremic syndrome (aHUS) is a set of heterogenous disorders of thrombotic microangiopathy defined by thrombocytopenia, hemolytic anemia, and acute renal failure that is not mediated by shiga toxin. Factor Eight Inhibitor Bypassing Activity (FEIBA) is a concentrate of inactivated and activated coagulation factors that is approved for use to establish hemostasis in patients with hemophilia or acquired factor inhibitors. However, it has recently been used off-label as an anticoagulant reversal therapy among the general population. Read More

Clinical characteristics and outcomes of combined thrombolysis and anticoagulation for pediatric and young adult lower extremity and inferior vena cava thrombosis.

Pediatr Hematol Oncol 2021 Mar 1:1-16. Epub 2021 Mar 1.

Department of Radiology, Section of Interventional Radiology, Texas, Children's Hospital, Baylor College of Medicine, Houston, Texas, USA.

Effective treatment for acute, extensive, symptomatic lower extremity (LE) thrombosis involves thrombolysis in addition to anticoagulation. There is limited available data on the outcomes and safety of thrombolysis to help guide its use in pediatrics and young adults. A retrospective study of children and young adults (<21 years of age) that received catheter directed thrombolysis (CDT) for LE and inferior vena cava (IVC) thrombosis was performed over a 5-year span at a pediatric tertiary care center.
