Summary
Risk models for deep vein thrombosis (DVT) in patients with spontaneous intracerebral hemorrhage (sICH) show promise. However, current models require further validation before clinical use due to bias and heterogeneity.
Area of Science:
- Medical Research
- Clinical Epidemiology
- Neurology
Background:
- Spontaneous intracerebral hemorrhage (sICH) patients face a high risk of deep vein thrombosis (DVT).
- Accurate risk prediction models are crucial for effective thromboprophylaxis in this population.
- Existing models need systematic evaluation for clinical applicability.
Purpose of the Study:
- To systematically review and critically evaluate risk prediction models for DVT in sICH patients.
- To provide evidence-based references for clinical practice regarding DVT risk stratification.
- To identify key predictors for DVT in sICH.
Main Methods:
- Comprehensive literature search across multiple databases (PubMed, Embase, Scopus, etc.) up to July 2025.
- Independent screening, data extraction, and risk of bias assessment using the PROBAST checklist.
- Meta-analysis of AUC values for validated models and subgroup analyses to address heterogeneity.
Main Results:
- 19 risk prediction models were identified across 15 studies.
- Reported AUC values ranged from 0.710 to 0.988; pooled AUC for 11 validated models was 0.82 (95% CI: 0.78-0.85).
- Age, D-dimer, hematoma volume, and GCS score were significant DVT predictors in sICH.
Conclusions:
- Current DVT risk models for sICH demonstrate promising discriminative ability but lack robustness.
- High risk of bias and heterogeneity limit direct application in routine clinical decision-making.
- Key predictors (age, D-dimer, hematoma volume, GCS) can aid qualitative risk stratification and individualized thromboprophylaxis.

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...
01:17Hemorrhagic 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...
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...
01:29Hemorrhagic 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...
01:30Venous 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...
