What are the complications that can arise in the treatment of Cortical Venous thrombosis?

The patient had only headache and weakness of lower limbs.

ask the doctor. basically its a clot right being lodged in the wrong place and well it can cause instant death if not dissolved hence the right drugs and prompt medical attention is vital .  (+ info)

What are the clincal differences between arterial and venous thrombosis?

Blood clots in the deep vein, that is your big one that runs through your body is called Deep Vein Thrombosis and those are the serious ones that can go to your heart or lungs and sometimes kill you. Blood clot in the Arterial Veins are in the little veins that run through your body and they can hurt just as much and need to be treated also, but they can not break off and go to your heart or lungs. I have had both.  (+ info)

Can cortical venous thrombosis be cured without any residual neurological deficit?

Isolated cortical venous thrombosis is rare, it usully follows or followed by other conditions also. in yahoo answers it is very tough to answer your question. post complete details to get proper answer.
any ways in common if a major venous system is blocked by a thrombosis for longer duration, haemorrhage occurs, which may lead to neurological deficit, but in your case it is not the situation. so i feel the patient may not have residual effects.  (+ info)

Theoratically it is possible to cure Cortical Venous Thrombosis but probems are encuontered?

In diagnosis and treatment what are the pitfalls

It would not let me answer your other question for some reason right now, so I will try to here.
Central venous thrombosis (CVT) is a condition in which a blood clot forms in the veins/sinuses that drain the brain. These veins are separated into the superficial and deep venous systems and drain into special veins called sinuses. It is helpful to distinguish superficial vs. deep, because CVT in the deep vessels has a worse prognosis., Cortical veins are part of the superficial venous system. Cortical vein thrombosis without sinus involvement is rarely diagnosed, although it may commonly be overlooked, because it is difficult to diagnose, both clinically and radiologically. CVT accounts for 1-2% of strokes. Symptoms include: headache (Most common symptom), disturbances of consciousness and cognitive dysfunction, focal neurologic deficits (Stroke like symptoms, eg. Paralysis of one side of the body, speech difficulty, visual field defects), and seizures. There are at least two different mechanisms that may contribute to the clinical features of CVT. Thrombosis of cerebral veins or dural sinus can lead to damage of normal brain tissue with resulting dysfunction. The clot increases the pressure in the venous system and can lead to surrounding brain swelling (edema) and also bleeding into the brain tissue (intracranial hemorrhage.) There can also be impairment in emptying the CSF fluid that is the fluid that surrounds the brain and spinal cord. This can lead to a buildup in CSF fluid (hydrocephalus) and increased pressure around the brain (increased intracranial pressure.) These events do not occur in all patients with CVT, but are possible.
Several conditions can increase the risk of having a CVT. It is recommended that all adults with CVT be evaluated for these risk factors. The risk factors include: Hypercoagable states in which there is an increased risk of forming blood clots. There are certain blood tests a doctor can check to evaluate for these condtions. Other risk factors include, oral contraceptive use, pregnancy, cancer, infection and head injury
Diagnosis is made with MR venography or CT venography. If the clinical suspicion is high and the CT or MRI was normal, then cerebral venous angiogram may be performed in which the doctors enter the venous system and shoot IV dye to evaluate for clot. Cortical vein thrombosis is more difficult to diagnose than thrombosis of the other sinuses. There is a sign on imaging called the "cord sign" that is specific to cortical vein thrombosis, but it may not always be present.
The treatment of CVT is with medications that thin the blood to help dissolve the clot and prevent future clots from occurring. It is also important to treat the underlying cause if possible to prevent future clot formation. The medications used to thin the blood include heparin and Coumadin (Warfarin). Heparin is used initially can be given through an IV (unfractionated heparin) continuously or there are formulations called low molecular weight heparin that can be given by subcutaneous injection once or twice daily. Unfractionated heparin through the IV requires frequent lab monitoring (aPTT), so low molecular weight heparin is usually preferred. . After the patient has been on heparin, then oral Coumadin will be started. Coumadin thins the blood in a different way and the therapeutic effects can be monitored with a blood test called the PT/INR. Goal INR is 2-3 in most cases of CVT. Heparin can be discontinued once the INR is in the therapeutic range. The length of Coumadin therapy is debated, but it is dependent on the cause and the reversibility of risk factors for future clot. Generally, Coumadin therapy is recommended for 6-12 months, for most patients. Thrombolytics (clot busting medication) can also be used in some cases, but has not been extensively researched. It is reserved for patients with deteriorating clinical status on Heparin/Coumadin. The decision to use thrombolytics is based on the risk benefit ratio.
In regards to prognosis, CVT can result in death or permanent disability, but usually has a favorable prognosis. Since cortical vein thrombosis is a rare type of CVT the prognosis has been less studied, but is believed to be more favorable than CVTs in general. A study known as the International Study on Cerebral Vein and Dural Sinus Thrombosis (ISCVT) evaluated 624 patients (age >15 years) with CVT found that 27 patients (4.3 percent) died during the acute phase, and 21 (3.4 percent) died within 30 days from symptom onset. At 16 months follow up, 57% of patients had a complete recovery and only 2.2% had severe functional impairment. Factors associated with a worse prognosis, included depressed level of consciousness (coma), altered mental status, thrombosis in the deep venous system, right hemisphere hemorrhage, and lesions located towards the back of the brain (posterior fossa lesions.) There was a meta-analysis performed to evaluate long term outcomes by reviewing the results of several studies. They found that CVT was associated with a 15% overall death or dependency rate at follow up. They observed that the risk of death was related to underlying conditions. The predictors of poor long-term outcomes observed were infection in the central nervous system (encephalitis, meningitis), any cancer, thrombosis in the deep vein system, hemorrhage into the brain tissue, coma, abnormal mental status, age > 37, and male gender. So, overall prognosis is good if it is treated early with appropriate medications. You should discuss this with your doctor who would know the full details of the case, evaluation and treatment. I am not sure if you have this condition or someone you know. I hope I helped answer your question. Sorry if it is too technical. If you have any questions, let me know. Feel free to email me if you do. Good luck.  (+ info)

Is there anyone out there who suffers or has suffered with sagital sinus venous thrombosis?

I have been diagnosed with a blood clot in my brain and just wanted to know if there is anyone out there who has this or has had it. I was looking at getting it touch with someone as I am struggling to come to terms with it and deal with it as I was diagnosed with it a week after having my baby

I'm guessing that having a blood clot in the brain is potentially fatal... right?

Well even if it isn't, you should definantely seek help.
Go see your doc, they can sort out all the support networking you need, and give you some good advice.

Or if your not the type to talk with strangers then talk it over with close friends.

Keep smiling and good luck!

Can Cortical Venous Thrombosis be classified as a Cerebrovascular accident?

Yes it can. Cerebrovascular accident is the medical term for a stroke or disease that affects the vessels in the brain leading to a neurologic deficit (weakness, speech difficulty, etc.) There are several types of cerebrovascular accidents, such as ischemic and hemorrhagic (bleeding). Cortical venous thrombosis is a rare cause. Good luck.  (+ info)

Is early diagnosis of Cortical Venous Thrombosis a medical challenge?

There are many imaging techniques but how far they are useful in the absence of clinical signs except headche

The incidence of cerebral venous thrombosis (CVT) is three to four cases per one ... Headaches present a diagnostic and therapeutic challenge for emergency physicians. ... The patient had a past medical history of B-12 deficiency anemia. ..... a clinical marker in early diagnosis of cerebral venous thrombosis?  (+ info)

Is timely diagnosis of Cortical Venous Thrombosis a challenge?

The diagnosis of the disease is usually by computed tomography (CT/CAT scan) or magnetic resonance imaging (MRI) employing radiocontrast to demonstrate obstruction of the venous sinuses by thrombus.Treatment is with anticoagulants (drugs that suppresses blood clotting), and rarely thrombolysis (enzymatic destruction of the blood clot). Since there is usually an underlying cause for the disease, tests may be performed to look for these. The diagnosis may be suspected on the basis of the symptoms, for example the combination of headache, signs of raised intercranial pressure and focal neurological abnormalities, or when alternative causes of headache and neurological abnormalities, such as a subarachnoid hemorrhage, have been excluded.The disease may be however complicated by raised intracranial pressure, which may warrant surgical intervention such as the placement of a shunt.So like heart attack or cerebral stroke,early intervention is always welcome.

Why is there an increased risk for venous thrombosis after a heart attack?

After heart attack; I believe due to the damage of heart muscle leading to a reduced EF and possible clot formation within the heart, the person is at risk for venous thrombosis... ??

Please be more specific. Are you referring to the recovery period soon after the heart attack when the patient is not active? Or are you asking in general? You can find info on venous thrombosis on the web, if that helps.  (+ info)
