Abstract:
Venous compressive disorders are a heterogenous group of vascular syndromes characterized by extrinsic venous compression that can lead to complications of venous hypertension or venous thrombosis. Endovascular damage secondary to deep venous thrombosis (DVT) can result in post-thrombotic syndrome (PTS), a potentially debilitating condition that can be associated with significant morbidity in the pediatric population. Here we discuss 4 venous compressive disorders: iliac vein compression (May-Thurner syndrome [MTS]); subclavian vein compression at the venous thoracic inlet (Paget-Schroetter syndrome); left renal vein compression (nutcracker syndrome); and popliteal vein compression (popliteal entrapment syndrome) with a focus on clinical evaluation and diagnostic methods. Where endovascular therapy is appropriate, specific procedural considerations including procedure indications, equipment, procedural steps, technical challenges, complications, clinical follow-up and expected outcomes are discussed.

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...

What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system...
01:11Overview 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...
