Stroke, Brain Tumor and Spinal Cord Patients at High Risk for Life-Threatening Blood Clots, Loyola Neurologists Report

Neurologic and neurosurgical patients are prone to blood clots because they are immobile or because their blood is more likely to coagulate. But physicians often fail to recognize blood clots in such patients. And even when a blood clot is diagnosed, physicians sometimes fail to treat it with blood-thinning medications due to the risk of hemorrhage.

A blood clot is known as a venous thromboembolism (VTE). A VTE can be either a blood clot in the arms or legs, known as deep venous thrombosis (DVT), or a blood clot in the lungs, known as a pulmonary embolism (PE). A DVT can come loose and travel to the lung. Twenty-five percent of patients with DVT die as a result of subsequent pulmonary embolism, and the seven-day mortality from PE is 75 percent.

“In the long run, the benefits in preventing recurrent VTE outweigh the risk of bleeding complications,” Dr. Michael J. Scheck and Dr. José Biller wrote in the February 2011 issue of the American Academy of Neurology journal Continuum.

In most neurologic and neurosurgical patients, beginning therapy with heparin blood-thinning medications within 24 to 48 hours “is both safe and effective,” Schneck and Biller wrote.

About 75 percent of stroke patients may develop DVT without prophylactic measures, such as blood-thinning medication, walking as early as possible and compression sleeves and stockings. There’s a “wealth of evidence” that such prophylactic measures reduce the frequency of DVT, PE and death in hospitalized patients, Schneck and Biller wrote.

“Neurologic and neurosurgical patients represent a high-risk subgroup because of underlying disease and immobility,” Schneck and Biller wrote. “Aggressive intervention for prevention and treatment of DVT is imperative.”

Schneck is medical director of Loyola’s Neurosciences Intensive Care Unit and vice chair of Research and Faculty Development in the Department of Neurology. Biller is chairman of the Department of Neurology at Loyola University Chicago Stritch School of Medicine.

Biller is guest editor of the February issue of Continuum. The theme of the issue is neurologic complications of systemic disease.

Also in the February issue, Loyola neurologists Dr. Matthew McCoyd and Dr. Gregory Gruener describe the neurologic aspects of lymphoma and leukemias.

“Although our understanding of the various presentations of these blood disorders has evolved along with our knowledge of the malignancies, accurate diagnosis can still be difficult,” McCoyd and Gruener wrote.

McCoyd is an assistant professor and Gruener is a professor in the Department of Neurology. Gruener also is director of Loyola’s Leischner Institute for Medical Education.

Based in the western suburbs of Chicago, Loyola University Health System is a quaternary care system with a 61-acre main medical center campus, the 36-acre Gottlieb Memorial Hospital campus and 28 primary and specialty care facilities in Cook, Will and DuPage counties. The medical center campus is conveniently located in Maywood, 13 miles west of the Chicago Loop and 8 miles east of Oak Brook, Ill. The heart of the medical center campus, Loyola University Hospital, is a 569-licensed-bed facility. It houses a Level 1 Trauma Center, a Burn Center and the Ronald McDonald® Children’s Hospital of Loyola University Medical Center. Also on campus are the Cardinal Bernardin Cancer Center, Loyola Outpatient Center, Center for Heart & Vascular Medicine and Loyola Oral Health Center as well as the LUC Stritch School of Medicine, the LUC Marcella Niehoff School of Nursing and the Loyola Center for Fitness. Loyola’s Gottlieb Memorial Hospital campus in Melrose Park includes the 264-bed community hospital, the Gottlieb Center for Fitness and the Marjorie G. Weinberg Cancer Care Center.
