    Welcome back to Vascular Medicine - The Advanced Venues. We are going to discuss today venous diseases. We’ve been talking a lot about arterial diseases up to this point. Now we’re going to look at the second component of the cardiovascular system: the venous diseases. We’re going to start with a definition of the various kinds of venous diseases. It turns out that, just as in the arterial disease, thrombosis – or the development of a blood clot –can develop in patients in the veins just as they can in the artery. And just as in the artery, pieces of the blood clot can break off and go elsewhere in the circulation and cause mischief. The same thing can happen in the venous system. In the venous system, when a blood clot forms and breaks off it goes to the lung and is known as pulmonary embolism. What often leads to clot in the veins is an inflammatory process called deep venous thrombosis or DVT. And that inflammation in the wall of the vein – and we’ll talk about the reasons why that can happen – results in a blood clot forming. The blood clot can get bigger and bigger and bigger, pieces can embolize and result in pulmonary embolism. If enough blood clot gets into the lung, you can have enough obstruction of blood flow through the lung that the patient may develop shock – the subject of the last lecture. So, often this disease is called venous thromboembolism because there’s clots in the leg and there’s clots embolising to the lung. And that’s often abbreviated as VTE. Remember what a thrombus is. A thrombus is a solid mass of platelets and / or fibrin that has formed locally in a vessel. It’s a blood clot. And it forms...
