Respiratory Medicine Case Reports
|September 15, 2022
Summary
Pulmonary vein thromboses (PVT) is a serious complication of lung cancer, potentially leading to arterial emboli. This case highlights PVT in a patient with lung mass, resulting in widespread organ infarction.
Area of Science:
- Cardiovascular Medicine
- Oncology
- Radiology
Background:
- Pulmonary vein thromboses (PVT) can arise as a complication of lung malignancy.
- PVT may lead to arterial embolic events, causing significant morbidity.
Observation:
- A 69-year-old female with coronary artery disease and pneumonia presented with neurological and abdominal symptoms.
- Imaging revealed bilateral strokes, renal infarction, and splenic infarction.
- A right upper lobe lung mass was identified, compressing the pulmonary veins and showing signs of thrombus.
Findings:
- CT angiogram, echocardiogram, and MRI confirmed PVT.
- The lung mass was the likely cause of the pulmonary vein compression and thrombus formation.
Implications:
- This case underscores the critical link between lung malignancy, PVT, and systemic arterial embolism.
- Prompt diagnosis and anticoagulation are crucial for managing PVT and preventing further embolic events.
- Treatment should address both the thrombosis and the underlying malignancy.

35
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

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...

28
A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

37
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 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...

29
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...
