Calf haematoma following anticoagulants in synovial rupture
The New Zealand Medical Journal
|September 8, 1982
Insights
Synovial rupture of the knee can mimic deep vein thrombosis (DVT), leading to incorrect anticoagulant treatment. Diagnostic imaging like venography or arthrography is crucial to avoid dangerous misdiagnoses in calf hematoma cases.
Area of Science:
- Orthopedic Surgery
- Vascular Medicine
- Diagnostic Imaging
Background:
- Calf hematomas can present with symptoms similar to deep vein thrombosis (DVT).
- Misdiagnosis of DVT can lead to inappropriate anticoagulant therapy.
- Rupture of the knee synovium is a potential cause of calf hematoma.
Observation:
- Four cases are presented where knee synovium rupture was misdiagnosed as DVT.
- Patients received unnecessary anticoagulant treatment due to the incorrect diagnosis.
- Clinical presentation of synovial rupture can closely resemble DVT.
Findings:
- Synovial rupture of the knee can mimic deep vein thrombosis (DVT) clinically.
- Incorrect diagnosis led to the administration of potentially dangerous anticoagulant therapy.
- Diagnostic imaging is essential for accurate differentiation.
Implications:
- Increased awareness of synovial rupture as a differential diagnosis for calf hematoma is needed.
- Venography and/or arthrography should be considered before anticoagulation when DVT is suspected but uncertain.
- Avoiding misdiagnosis prevents risks associated with unnecessary anticoagulant use and allows for appropriate management of synovial rupture.
Abstract:
Four cases of calf haematoma are described in which an incorrect diagnosis of deep vein thrombosis (DVT) was made of rupture of the knee synovium, and led to inappropriate anticoagulant therapy. Awareness of how closely synovial rupture of the knee can simulate DVT should prevent such mistakes. Where there is doubt venography and/or arthrography are advocated before prescribing anticoagulants which can be dangerous as there may already be bleeding from the rupture site.

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...

The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the knee,...

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 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...

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.

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...
