In the veins . The Doppler ultrasound test would confirm the location. Deep-vein clots must be treated more aggressively because there is a risk that the clot will travel and cause an embolism, a blockage of blood flow, especially to the heart or lungs. Blood clots in the superficial veins to do not result in embolism to the heart or lungs. Aneurysms Aneurysms, the result of weakness in an arterial wall, rarely cause symptoms until they progress to a usually fatal rupture.
Early detection is therefore crucial for preventing rupture.
An aneurysm might be detected during a physical examination as a deep pulsation, typically in the abdomen just above the navel, or it might be discovered during an X-ray or imaging test done for some other reason. You are more likely to be monitored for an aneurysm if you have a family history of them. Aneurysms most often involve the aorta, the major artery carrying blood away from the heart, although the diagnostic process and treatment are the same for those in less common locations. If an aortic aneurysm is suspected, your physician will recommend an abdominal ultrasound. If an aneurysm is identified, it will be treated according to its size, since larger ones are more likely to rupture.
