A catheter, which is a long and thin tube, is inserted into a large artery in the arm or groin area. It is then guided along the artery to the targeted blood vessel to be examined. An imaging dye is loaded into the blood vessel through the catheter and the movement of the dye in the blood vessel is recorded as an angiogram. [18]

Inferior vena cava syndrome (IVCS) is a very rare constellation of symptoms resulting from either obstruction or stenosis of the inferior vena cava. It can be caused by physical invasion or compression by a pathological process, or by thrombosis within the vein itself. It can also occur during pregnancy. Symptoms including high venous pressure ...
Symptoms classically affect a leg and typically develop over hours or days, [20] though they can develop suddenly or over a matter of weeks. [21] The legs are primarily affected, with 4–10% of DVT occurring in the arms. [11] Despite the signs and symptoms being highly variable, [5] the typical symptoms are pain, swelling, and redness.
A catheter ablation is a minimally invasive procedure that stops the electrical impulses that cause irregular heart rhythms, according to the Mayo Clinic. A thin tube called a catheter is inserted ...
Symptoms of a DVT will include unilateral leg swelling and pain, warmth, and redness of the affected area. [9] This is due to the blockage of blood attempting to return to the heart through the venous system. Additional findings in a patient with a paradoxical embolism will be dependent upon where the emboli lodges and disrupts blood flow.
An embolectomy is a procedure conducted when a blockage moves from its original site to another place in the body, thus forming an embolus. There are two methods of performing embolectomy. [15] The first method is catheter embolectomy, which involves the insertion of a catheter into the affected artery and the subsequent removal of the embolus.
Symptoms include chest pain or angina, shortness of breath, and fatigue. [6]A completely blocked coronary artery will cause a heart attack. [6] Common heart attack symptoms include chest pain or angina, pain or discomfort that spreads to the shoulder, arm, back, neck jaw, teeth or the upper belly, cold sweats, fatigue, heartburn, nausea, shortness of breath, or lightheadedness.
