Venous Thrombosis I: Introduction01:30

Venous Thrombosis I: Introduction

641
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...

Venous Thrombosis III: Interprofessional Care

455
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...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

422
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...

Venous Thrombosis IV: Nursing Management

360
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,...

Veins of the Abdomen and Pelvis01:18

Veins of the Abdomen and Pelvis

2.0K
The human body is a complex system of interconnected parts, and the circulatory system plays a crucial role in maintaining overall health. One key component of this system is the inferior vena cava, a large vein responsible for returning blood from the abdominopelvic viscera and abdominal walls to the heart.
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

629
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Venous tumor thrombus from a pelvic osteosarcoma.

    Radiology Case Reports

    PubMed
    Summary

    This case study highlights a rare instance of pelvic osteosarcoma in a young woman, complicated by an extensive tumor thrombus. Such venous extension is uncommon in osteosarcoma cases.

    Area of Science:

    • Oncology
    • Vascular Surgery
    • Radiology

    Background:

    • Osteosarcoma is a primary bone malignancy typically affecting long bones.
    • Pelvic osteosarcomas are less common and can present unique diagnostic and management challenges.
    • Tumor thrombus formation, while known in other cancers, is infrequently reported with osteosarcoma.

    Observation:

    • An 18-year-old female presented with pelvic osteosarcoma.
    • A significant tumor thrombus was identified originating in the left iliac vein.
    • The thrombus extended into the inferior vena cava, indicating advanced disease.

    Findings:

    • This case represents one of only 14 documented instances of tumor thrombus associated with osteosarcoma in the medical literature.
    • The pelvic location of the osteosarcoma contributed to the extensive venous involvement.

  • The tumor thrombus highlights the potential for vascular invasion in pelvic osteosarcoma.

    • Implications:

    • This case underscores the importance of considering vascular invasion in pelvic osteosarcoma, even when rare.
    • Advanced imaging is crucial for detecting tumor thrombus and assessing its extent.
    • Further research into the mechanisms and management of tumor thrombus in osteosarcoma is warranted.
