Lacunar Infract - Oren Zarif - Lacunar Infarct


Symptoms of lacunar infarct are usually subtle and not always obvious. A doctor may perform a CT scan to get a better picture of the brain. The CT imaging isn't as accurate as magnetic resonance imaging, but the doctors can still use it to see if there are blood vessel blockages. If a CT scan doesn't show the infarct, a doctor may perform a CT angiography to rule out other causes of the condition.

There is also a debate about the mechanism of lacunes. Some researchers believe that it is caused by emboli that lodge in the larger arteries. Others argue that the condition is caused by the heart itself. Other studies, though, cannot establish causality and focus on symptomatic patients. In the present study, a single lacunar infarct was found in a third patient. However, this study did not identify any other risk factors for lacunar infarcts.

A single penetrating branch occlusion or a micro atheroma of the lenticulostriate artery can cause a lacunar infarct. Other causes of small cerebral infarcts include embolism and infections. However, no one has been able to prove that vasospasm is the cause of lacunar infarcts.

Although lacunar strokes are rare, the symptoms are very similar to those of large-vessel atherosclerosis. Microatheroma involves lipid-laden macrophages and subintimal deposits of fibroblasts. Patients may experience hemiplegia or severe weakness in the lower body. Patients may present with a variety of symptoms, depending on the area of the brain affected.

Although there is not a single cause of lacunar infarcts, a genetic link to a family history of stroke is thought to increase your risk. During your annual physical examination, be sure to check for any health problems that may increase your risk of a stroke. For example, if you have high cholesterol or sleep apnea, your doctor might recommend treatment for these conditions. Any type of stroke should be treated as quickly as possible.

MRI imaging of the deep white matter of the brain can also be helpful in tracking the progress of the WMH. This MRI scan can reveal the presence of new infarts that appear concomitantly with WMH progression. Researchers suggest that there may be an etiology-related difference between infarcts of the basal ganglia and deep white matter. There is a growing body of evidence that suggests a differential relationship between white matter hyperintensity volume and risk for new lacunar infarct.

When an infarct is small and located in the deep brain, it is known as a lacunar stroke. Compared to other types of strokes, a lacunar infarct has a favorable long-term prognosis. Once an infarct occurs, the risk of death is greatly increased from cardiovascular causes. Infarcts of the deep brain are classified as non-fatal if the patient does not receive diagnostic imaging.

Patients who developed new infarcts in the deep white matter were more likely to have a history of cerebrovascular disease. In fact, a previous history of WMH was associated with new lacunar infarcts. It appears that this is the most common cause of new infarcts in the deep white matter. It is important to recognize the risk factors associated with these types of infarcts when assessing patients.

Another symptom of lacunar infarct is weakness. Unlike in other stroke types, a lesion in the left hemisphere affects the opposite limb, and the symptoms of lacunar infarct depend on which hemisphere is damaged. Because different parts of the brain control different aspects of the body, a lesion in the right hemisphere may affect the right side as well.

A recent study evaluated whether CTP is superior to NCCT/CTA in diagnosing acute lacunar infarcts. The study included 1085 CTP examinations of patients with stroke symptoms within 12 hours of the onset of symptoms. Infarcts with a size of two centimeters or more were recorded. The patients' NIHSS scores were used to determine the cause of the infarcts.

Symptoms of lacunar infarct can vary, but in general, patients recover from their neurologic symptoms. Physical, occupational, and social therapies are essential, and continue to be vital in recovery. Pharmacists are especially important for patients on multiple medications. They can review any drug interactions and advise about possible side effects. Rehabilitation therapy must continue to maximize neurologic function, and patient care must be coordinated long term. This includes intensive antihypertensive and lipid-lowering medications, and strict monitoring of blood glucose levels.

There are several independent risk factors associated with lacunar infarct. These risk factors were analyzed for each one separately, and then were presented to a logistic regression analysis model. A stepwise method was used to create a logistic regression analysis model. The P value for this study was.01. There were five independent variables that were associated with lacunes. A higher creatinine level was associated with higher risk for symptomatic patients.
