1. Aneurysm
This is a localized dilatation of the lumen of a blood vessel. The most common sites of aneurysms are the aorta and the vessels of the brain.

2. Aortic aneurysm
Dangeous ballooning of the aorta (the main artery leaving the heart) which is caused by disease in the artery's wall.

3. Balloon angioplasty (percutaneous transluminal coronary angioplasty, PTCA)
This is a surgical procedure for the opening up of a narrowed or occluded coronary artery . It is a procedure for relieving angina and improvement of the patient's ability to exercise. It is successful in about 60% of the cases. Under local anesthesia and sedation , a small incision is made in the groin area so that a thin tubing with a balloon tip can be introduced. An x-ray machine is used to help the operator to guide the balloon tip into the blood vessels of the heart. When the balloon tip reaches its destination (the occluded vessel), the operator expands the balloon tip, which then dilates the occluded vessel. If the angioplasty is not desired by the patient, the physician can continue drug treatment if this is still to some extent effective. However, it may be that balloon angioplasty is recommended exactly because of the failure of drug treatment. Another alternative is open heart surgery for aorto-coronary bypass (A-C bypass), also known as coronary artery bypass surgery (CABG). The risks and side effects of this surgery can include anesthesia risks, bleeding, coronary artery dissection or intimal tear, occlusion of the blood vessel because of blood clots, irregular heart beat, heart attack, stroke, pericardial tamponade, need for emergency surgery, and recurrence of angina despite initial relief. Local vascular complications at the site of puncture include arterial thrombosis , arterial laceration or dissection, pseudoaneurysm , hematoma , and a-v fistula . The consequences of not having the treatment include continued angina, plus the possibility of suffering a heart attack and its consequences.

4. Brain scan
This is a technique to demonstrate the pattern of blood perfusion of the brain. The procedure involves intravenous injection of the radionuclide such as technetium 99m pertechnetate, mercury-210, or radioiodinated albumin . This method can diagnose cerebral hemorrhage, cerebrovascular accidents (CVA), tumor, hematoma , AV malformations, and aneurysm s.

5. Cardiac catheterization
This is a procedure involving the introduction of a catheter into the right side or the left side of the heart to study the pressures in the central vein, across the valves of the arteries and the chambers of the heart. The volumes in the cardiac chamber during the cardiac cycle and the patency of the coronary artery are also measured by observing the flow pattern of radiographic dye injected through the catheter. Right heart catheterization measures the right atrial, right ventricular, pulmonary artery and pulmonlary capillary wedge pressures, oxygen saturation, and cardiac output. The catheter is inserted through the femoral vein or subclavian vein. Left heart catheterization measures the aortic and mitral valve stenosis and regurgitations, global and regional left ventricular functions and coronary ateriography. The catheter is inserted through the femoral artery or the brachial artery. Alternative courses of action include: ultrasound, thallium scan, which can give an accurate idea of ventricular function, but neither can demonstrate the degree and location of obstruction of the coronary artery. Material effects, risks and side effects include: allergy to the radiography dye, bleeding, pneumothorax, arrhythmias, air emboli, pulmonary emboli, pulmonary artery rupture and infarction, cerebrovascular accident, myocardial infarction, perforation of the myocardium, infections, sepsis, vasovagal reactions. Local vascular complications at the site of puncture: arterial thrombosis, arterial laceration or dissection, pseudoaneurysm, hematoma, a-v fistula.

6. CT scan
This is an x-ray study of the body in which radiographic images of cross-sections of the body is obtained. CT scan of the brain may reveal tumor , infarction , hydrocephalus , cortical atrophy , cerebral aneurysm , hematoma , A-V malformation. Study of the chest may reveal tumor, lymph nodes, cysts, abscess, effusion , and aortic aneurysm. Study of the abdomen may reveal tumor, hematoma, cysts. In some studies the image can be improved by contrast dye. The major complication is allergy to the dye in some patients.

7. Dissecting aneurysm
A form of false aneurysm extended by blood.

8. False aneurysm
A false aneurysm is an apparent widening of a blood vessel (the external wall is expanded) without actual expansion of the entire lumen . This is usually the result of a hematoma between the layers of the vessel wall.

9. Headache
A headache is a sensation of aching of the head, a symptom. Headache could affect both the sides, front, and back of the head. It can be described as throbbing, steady, and burning. It may start abruptly, or gradually. It has many possible origins: migraine, problems related to blood vessels, sinuses, bleeding inside the skull, or tumor, etc. Some types of headache and their symptoms: * migraine: headache, nausea, vomiting, aura (transient focal neurological disturbances, e.g. visual, sensory, speech, photophobia). * tension: due to chronic scalp muscle contraction worsened by anxiety depression and unresolved conflicts. More than 80% of headache complaints belong to this category. * intracranial: infections, hemorrhage , tumor, trauma, epilepsy , etc. * secondary to other causes: sinusitis , aneurysm , ear infections, drug/alcohol side effects.

10. Kawasaki's disease (mucocutaneous lymph node syndrome)
This disease occurs mainly in children, and is characterized by fever that lasts longer than 5 days and which is not responsive to antibiotic treatment, plus the following mucocutaneous manifestations: * conjunctivitis * mucous membrane changes: cracked lips, strawberry tongue * extremity changes: edema , desquamation of tips of the toes and fingers, erythema , rash * lymphadenopathy of the neck greater than 1.5 cm A major complication is arteritis and aneurysm formation of the coronary vessels, myocarditis , pericarditis and acute myocardial infarction .
