Summary
Livedoid vasculopathy (LV) pathogenesis is clarified by coagulation disorders like hyperhomocysteinemia and prothrombin gene mutations. Some LV cases stem from pro-coagulable states in diseases, not true vasculitis.
Area of Science:
- Dermatology
- Hematology
- Pathogenesis Research
Background:
- The exact cause of livedoid vasculopathy (LV) remains largely unknown.
- Recent advancements in understanding coagulation disorders offer new insights into LV.
- LV is increasingly linked to specific genetic and acquired pro-coagulable states.
Purpose of the Study:
- To review current clinical case data on livedoid vasculopathy.
- To elucidate the pathogenesis of livedoid vasculopathy, focusing on coagulation abnormalities.
- To differentiate LV associated with coagulation disorders from inflammatory vasculitis.
Main Methods:
- Review of published clinical case studies on livedoid vasculopathy.
- Analysis of associations between LV and known coagulation disorders.
- Discussion of pathogenetic mechanisms based on clinical evidence.
Main Results:
- Livedoid vasculopathy is associated with hyperhomocysteinemia, activated protein C resistance, and prothrombin gene mutations.
- In systemic lupus erythematosus and polyarteritis nodosa, LV is likely caused by induced pro-coagulable states.
- These findings suggest a significant role for thrombotic events in LV pathogenesis.
Conclusions:
- Livedoid vasculopathy pathogenesis is increasingly understood through the lens of coagulation disorders.
- Distinguishing LV from true vasculitis is crucial, especially when associated with systemic diseases.
- Further research into thrombophilia is warranted for effective LV management.

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...
01:29Venous 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...
01:16Vascular Spasm
The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last for...
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.

01:30Inflammatory Response I: Vascular and Cellular
The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...
