Blood clots might occur anywhere in the human body. Outer blood clots are easier to treat, however, if the same occurs in the blood vessels, it can severely impact the movement of blood. The clots, if happened in a critical organ like a heart or a brain can be potentially fatal unless treatment is meted out immediately. Arterial thrombosis is a blood clot that occurs in an artery. It is potentially dangerous, as it can obstruct the blood flow to other major organs. Strokes can happen when this condition exists. A Cardiologist has to be consulted with immediately if the symptoms occur. Many factors contribute towards arterial thrombosis and acute arterial thrombosis. Some of them could be blood pressure, high cholesterol levels, heart diseases, injuries to the arteries and smoking. Arterial ischemia can also happen due to the clots. This is a disease that gets developed due to the clots that block the passage of blood. Some of the symptoms if a thrombosis occurs could be coldness, lack of pulse and lack of movement. An angiogram may be done by the Cardiologist to check the abnormalities in the blood vessel. Intra - Arterial Thrombolysis Treatment can include medications to an extent but in almost 80% of the cases an Angioplasty or an arterial thrombectomy may be performed to bypass a clot. It's a surgical technique used to open up a blocked or narrowed blood vessels.
