Mycotic Aneurysm

A mycotic aneurysm comes from irreversible damage to the walls of the artery due to an infection. Mycotic aneurysms come from an irreversible dilation of the artery that makes it two to two and a half larger than normal.

A mycotic aneurysm as said is due to destruction of the vessel wall from a bacterial infection. It is a serious condition and despite the name, which means fungal toxin, the majority of mycotic aneurysms are caused by bacteria. It may be a false or true aneurysm, the latter meaning it involves all layers or the former when only a portion of the arterial wall is effected.

Mycotic can be present anywhere in the human body. They may appear in patients with endocarditis, which is an inflammation of the thin membrane lining of the heart. Typically, a mycotic aneurysm occurs where the blood vessel branches off. During treatment for endocarditis, the aneurysms may increase, decrease, remain the same size, or disappear. It may also appear in multiples or be solitary.

Sign and Symptoms

What is so alarming about a mycotic is how dangerous they can be. After a blood vessel begins to swell, if the bulge becomes large enough, it will burst. The bulging causes the wall of an artery to weaken. Regardless of location, it may cause localized pain and symptoms of infection such as fever.

A mycotic aneurysm can happen at any age. Mycotic cerebral aneurysm is a rare but serious complication of infective inflammation of the heart. In this case, usually the patient receives a warning sign of an excruciating headache.

Surgery is usually needed to repair brain aneurysms. Other aneurysms are often repaired with less invasive methods. Some warning signs, found in only a fraction of patients are double vision, headaches, dilated pupils, and pain around the eye.

If an aneurysm bursts, warning signs include: the worst headache of your life, vomiting, blurred or doubled vision, stiff neck, nausea, sensitivity to light, and loss of sensation in the extremities. Do not shrug off the symptoms until it is too late. Especially if you have any of the risk factors, see a doctor right away!

Causes

One cause of reoccurring headaches that often get overlooked is a brain aneurysm. Left untreated, an aneurysm can rupture, which can be fatal to the sufferer. Each year, 25,000 Americans are stricken by ruptured aneurysms.

A mycotic may be caused by a septic brain mass that blocks blood vessels causing inflammatory destruction of the arterial wall. A likely explanation is that infected blood clot material reaches the outer covering through the blood vessel. Inflammation then destroys the outer covering resulting in mycotic aneurysm.

Mycotic were on the decrease in the antibiotic era. However, with the increased incidence of drug abuse, mycotic aneurysms may be on the rise. The chest aorta has been described as the most common site of aneurysm mycotic . Aneurysm Mycotic in the skull are less common but occur with greater frequency in children.

Treatment

Mycotic aneurysms normally have a fusiform structure and usually bleed easily, making treatment difficult. Most cases are treated with antibiotics, which are continued for 4-6 weeks. Aneurysms may continue to shrink following antibiotic therapy. Coiling or clipping may be possible if the aneurysm fails to shrink after completion of antibiotics.

While there is some controversy over the type of treatment for mycotic, there are two accepted forms of treatment. One is surgery and the other is with a course of antibiotics and other medical treatments. Most doctors consider the location and often start with a course of antibiotics and take a wait and see attitude to see if surgery is necessary. Sometimes the antibiotics reduce the mycotic aneurysm. Since doctors have varying philosophies and treatment varies due to location and severity, discussing the best option for treatment is the best route to take.

Diagnosis

Early diagnosis improves outcome. Fever is usually the first sign in 70% of cases. Early diagnosis is critical, but often unsuspected, due to the gradual onset of symptoms related to infection. Diagnostic tools usually are X-ray, ultrasound, CT scan, or MRI. Mycotic results from local infections such as sepsis or pneumonia. If a mycotic is suspected, fungal and bacterial blood cultures are obtained.

Risk factors

Localized infection can cause mycotic. The risk factors for aneurysms include age, high blood pressure, atherosclerosis, and hereditary. It is estimated that nearly 2 million people have an undetected aneurysm. These aneurysms remain unnoticed because they have not ruptured. Once a brain aneurysm ruptures the risk of stroke increases.

Fortunately, surgery is available to treat aneurysms before they rupture. The good news about brain aneurysms is that surgery is usually able to restore health if done within 24 hours of the rupture. More importantly, there are ways to help prevent a brain aneurysm.
