Summary
Inherited thrombophilias (IT) increase the risk of venous thromboembolism (VTE) in children, both for initial onset and recurrence. Screening for IT is crucial for effective VTE management in pediatric patients.
Area of Science:
- Pediatric Hematology
- Thrombosis and Hemostasis
- Genetics
Background:
- Venous thromboembolism (VTE) is increasingly diagnosed in children, often secondary to severe illnesses.
- Inherited thrombophilias (IT) are recognized risk factors for VTE in adults and are investigated as contributing factors in pediatric VTE.
- Recurrence rates for VTE in children are approximately 3% in neonates and 8% in older children.
Purpose of the Study:
- To review the impact of inherited thrombophilias (IT) on the early onset and recurrence of venous thromboembolism (VTE) in children.
- To evaluate the clinical significance of detecting IT in pediatric VTE cases.
- To highlight the importance of a pediatric thrombophilia screening program.
Main Methods:
- Review of existing literature on inherited thrombophilias and pediatric VTE.
- Analysis of statistically significant associations between specific IT traits and VTE onset/recurrence.
- Calculation of absolute risk increases for VTE recurrence associated with various IT conditions.
Main Results:
- Statistically significant associations were reported between IT traits (Factor V G1691A, Factor II G20210A, Protein C, Protein S, Antithrombin deficiency, elevated Lipoprotein (a)) and VTE onset.
- Significant associations with recurrent VTE were found for Protein S deficiency, Antithrombin deficiency, Factor II variant, and combined IT.
- Absolute risk increase for VTE recurrence ranged from 9.8% (Factor II variant) to 29% (combined IT and Protein S deficiency).
Conclusions:
- Detection of inherited thrombophilias is clinically meaningful in children with VTE.
- A pediatric thrombophilia screening program is important for identifying children at higher risk of VTE.
- Treatment algorithms for pediatric VTE should consider the presence of IT.

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...
01:24Disorders of Hemostasis
Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

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...
01:29Venous 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...
01:20Venous 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...
01:19Pulmonary Embolism I: Introduction
A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...
