Introduction

Deep vein thrombosis (DVT) is a serious medical condition characterized by the formation of a blood clot in the deep veins, usually in the legs. It often results from a combination of factors that promote hypercoagulability, venous stasis, and vascular injury, as outlined in Virchow’s triad (Murphy & Nelson, 2020). Leona’s case presents an interesting intersection of risk factors, including her lifestyle, comorbid conditions, and environmental changes, which collectively contributed to her development of DVT during her trip. This essay explores the pathophysiological mechanisms behind her condition, analyzing how her risk factors, physiological alterations, and medical interventions interplay to influence her health outcome.

Physiological Background and Risk Factors for DVT

Leona’s development of DVT can be understood through the lens of hypercoagulability, venous stasis, and vascular injury, with her personal health history exacerbating these factors. Hypercoagulability refers to an increased tendency for blood clot formation, often influenced by genetic or acquired factors (Wang et al., 2022). In Leona’s case, her smoking, overweight status, and atherosclerosis create a prothrombotic environment. Smoking damages the endothelium lining blood vessels, increasing the likelihood of clot formation by promoting inflammation and platelet aggregation (Bhat et al., 2019). Overweight status contributes to venous stasis and increased pressure in the lower extremities, especially during prolonged immobility, such as long flights (Kakkar et al., 2018). Atherosclerosis, characterized by plaque buildup within arteries, also affects endothelial function, leading to a higher risk of thrombotic events due to endothelial injury and inflammatory responses.

Additionally, her recent extended travel to Australia—a period during which she was immobile—further compounded her risk. Prolonged immobility leads to blood pooling and slows circulation in the lower extremities, which predisposes to clot formation. Venous stasis is a critical factor in DVT development as reduced flow promotes local clotting (Kearon et al., 2019).

Impact of Atherosclerosis on Platelet Function and Vice Versa

Atherosclerosis significantly influences platelet activity, mainly through endothelial dysfunction. Healthy endothelium produces antithrombotic substances like nitric oxide and prostacyclin, which inhibit platelet aggregation. In atherosclerotic vessels, damaged endothelium shifts the balance toward a prothrombotic state by exposing subendothelial collagen, leading to platelet activation and adhesion (Kolb et al., 2021). This process promotes thrombus formation, particularly at sites of plaque rupture.

Conversely, increased platelet activity accelerates atherosclerotic plaque development via the release of growth factors such as platelet-derived growth factor (PDGF), which promotes smooth muscle proliferation and further plaque formation (Li et al., 2020). This positive feedback loop exacerbates both conditions and increases the risk for thrombotic cardiovascular events, such as myocardial infarctions and strokes.

Blood Coagulation, Immobility, and Atherosclerosis

Immobility, as experienced during long flights, leads to venous blood pooling, diminished venous return, and a hypercoagulable state. Reduced shear stress within blood vessels enhances coagulation factor expression, inclining toward clot formation (Kakkar et al., 2018). Simultaneously, atherosclerosis contributes to a disturbed vascular endothelium, which promotes coagulation through increased tissue factor expression and decreased production of antithrombotic molecules, creating an environment supporting thrombus development (Kolb et al., 2021).

The combination of immobility and atherosclerosis amplifies clotting risk through additive effects—static blood flow stimulates clotting factor accumulation, while damaged endothelium expresses more tissue factors, triggering the coagulation cascade. These processes are fundamental in the pathogenesis of DVT in at-risk individuals like Leona.

Heparin Therapy in DVT Management

Heparin is an anticoagulant used to treat DVT by enhancing the activity of antithrombin III, which inhibits thrombin and factor Xa, key enzymes in the clotting process (Hirsh et al., 2020). Initiating heparin therapy in Leona’s case aims to prevent clot extension and embolization, reducing the risk of pulmonary embolism, a life-threatening complication of DVT.

The choice of hospital administration rather than oral heparin tablets—such as warfarin or direct oral anticoagulants—stems from the need for rapid onset of action and the need for close monitoring of anticoagulant effects. Parenteral heparin allows for controlled dosing and immediate adjustments based on coagulation parameters (Hirsh et al., 2020). Additionally, during hospitalization, frequent blood tests can monitor activated partial thromboplastin time (aPTT) to ensure therapeutic levels.

Leona was not prescribed heparin tablets for outpatient use initially because oral anticoagulants require careful monitoring, dose adjustments, and have a delayed onset of action. Once stabilized, transitioning to oral anticoagulants can be considered for long-term management, but during acute phases, intravenous or subcutaneous heparin remains the preferred choice.

Conclusion

Leona’s case exemplifies the multifactorial nature of DVT development, highlighting how lifestyle, comorbidities, and environmental factors coalesce to influence thrombotic risk. Her smoking, obesity, and atherosclerosis synergize to create a prothrombotic vascular environment, which, coupled with prolonged immobility during travel, precipitated her DVT. Understanding the pathophysiological mechanisms—from endothelial dysfunction and platelet hyperactivity to coagulation cascade activation—is vital in managing and preventing such thrombotic events. Heparin therapy remains a cornerstone in acute DVT treatment, tailored to the patient’s clinical status for optimal outcomes.
