Abstract:
The risk factors and clinical presentation of splanchnic vein, cerebral vein, and renal vein thrombosis are distinct from those for extremity thrombosis. Because of the rarity of these conditions and a paucity of data guiding appropriate management, providers frequently struggle to manage thromboses at unusual sites. In this article, the authors review the site-specific risk factors, clinical presentation, diagnostic techniques, and literature on anticoagulant and procedural management of thrombosis at unusual sites to guide providers.

Overview of Systemic Veins
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...

Assessment of the Cardiovascular System III: Palpation
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
Veins of Lower Limbs
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...
Veins of the Abdomen and Pelvis
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...
