Summary
Deep venous thrombosis (DVT) affects less than 10% of acute stroke patients, primarily those with ischemic stroke. Pre-stroke disability and elevated C-reactive protein are key risk factors, but DVT does not significantly impact 3-month outcomes.
Area of Science:
- Neurology
- Vascular Medicine
- Medical Diagnostics
Background:
- Deep venous thrombosis (DVT) is a recognized complication following stroke.
- Understanding DVT incidence and risk factors in acute stroke patients is crucial for preventative strategies.
Purpose of the Study:
- To determine the frequency of DVT in acute stroke patients.
- To identify risk factors associated with DVT development post-stroke.
- To evaluate the impact of DVT on 3-month patient outcomes.
Main Methods:
- Prospective enrollment of 323 consecutive acute stroke patients.
- Ultrasound imaging performed within 7 days of stroke onset.
- Multivariate analysis to identify independent risk factors.
Main Results:
- Deep venous thrombosis (DVT) was detected in 8.7% of patients, exclusively in those with ischemic stroke.
- Independent risk factors for DVT included elevated C-reactive protein (CRP) levels (OR 3.15) and prestroke disability (Modified Rankin Scale 3-5, OR 2.89).
- DVT did not significantly influence the 3-month outcomes for stroke patients.
Conclusions:
- Deep venous thrombosis (DVT) is an infrequent complication (<10%) in acute stroke.
- Prestroke dependency and elevated baseline CRP levels are significant independent risk factors for DVT in stroke patients.
- The presence of DVT does not appear to adversely affect the 3-month prognosis after acute stroke.

01:29Venous Thrombosis III: Interprofessional Care
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
01:30Venous Thrombosis I: Introduction
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
01:20Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
01:30Venous Thrombosis IV: Nursing Management
Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...
01:29Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
01:17Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
