Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

Venous 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...

Overview of Systemic Veins

Overview of Systemic Veins

Systemic veins are crucial blood vessels that return deoxygenated blood from various body tissues back to the heart. There are three systemic veins that return deoxygenated blood to the heart, they are as follows.
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...

Pulmonary Embolism I: Introduction

Pulmonary Embolism I: Introduction

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...

Esophageal Varices-I: Introduction

Esophageal Varices-I: Introduction

Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

Varicose Veins II: Diagnostic Studies and Interprofessional Care

Varicose Veins II: Diagnostic Studies and Interprofessional Care

Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

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...

Summary

Meandering pulmonary veins, a rare vascular anomaly, can occur on the left side and be associated with scimitar syndrome. Multi-detector computed tomography aids in diagnosis without invasive procedures.

Area of Science:

Cardiovascular Imaging
Thoracic Radiology
Congenital Vascular Anomalies

Background:

Meandering pulmonary vein (MPV) is a rare congenital anomaly characterized by a circuitous unilateral pulmonary vein draining into the left atrium.
While typically right-sided, MPVs can present on the left and may be associated with scimitar syndrome.

Observation:

Two cases are presented: a 71-year-old woman with left-sided MPV and a 20-year-old man with right-sided MPV and scimitar syndrome features.
Both patients were incidentally found to have abnormal chest radiographs.

Findings:

Multi-detector chest computed tomography (MDCT) with 3D reconstruction accurately depicted the vascular anatomy in both patients.
The 71-year-old woman had an isolated left-sided MPV, while the 20-year-old man had a right-sided MPV with scimitar syndrome features.

Implications:

This study highlights that left-sided MPVs can occur and may coexist with scimitar syndrome.
MDCT with 3D reconstruction is a valuable non-invasive tool for diagnosing MPVs and associated anomalies, potentially avoiding invasive diagnostic procedures.
