Anatomy Note

This article explores the radiological appearance of deep vein thrombosis within the common iliac vein as seen on an abdominal computed tomography (CT) scan. We will examine the clinical significance of iliac vein thrombosis, the anatomy of the pelvic venous system, and the critical role of diagnostic imaging in preventing complications like pulmonary embolism.

This article presents a detailed analysis of a Doppler ultrasound scan taken from the right leg of a 65-year-old male patient presenting with significant swelling. The image clearly highlights the physiological and anatomical differences between patent blood vessels and those obstructed by pathology. We will examine the specific radiological signs of Deep Vein Thrombosis (DVT) in the subsartorial vein, contrasting the absence of blood flow in the thrombosed vessel against the healthy flow observed in the adjacent femoral artery and deep femoral vein.

This article provides a detailed clinical analysis of a medical ultrasound scan revealing a thrombus within the left common femoral vein. We will explore the radiological appearance of deep vein thrombosis (DVT), the anatomical significance of the femoral vasculature, and the pathophysiology of venous clotting disorders. Understanding these imaging findings is essential for the timely diagnosis and management of thromboembolic conditions, which prevents severe complications such as pulmonary embolism.

This article provides a detailed analysis of a Computed Tomography (CT) scan displaying a saddle pulmonary embolism, a critical medical emergency characterized by a large blood clot lodging at the bifurcation of the main pulmonary artery. We will explore the radiological signs evident in the image, the pathophysiology of this life-threatening condition, and the standard clinical protocols used for diagnosis and management.

Hemostasis is a complex physiological balancing act involving the formation of blood clots to stop bleeding and the subsequent breakdown of those clots to restore normal blood flow. The process of generating D-dimers begins with the soluble protein fibrinogen and ends with the enzymatic degradation of a stabilized fibrin clot. Understanding this pathway is clinically vital, as the detection of D-dimers in the bloodstream serves as a critical diagnostic marker for thrombotic disorders such as deep vein thrombosis (DVT) and pulmonary embolism (PE).
