What Is Cerebral Venous Sinus Thrombosis?

Hello Rescuers!

I received an email from a RoyOnRescue friend who had suffered a head injury while playing a sport.  After being seen by the doctor he was diagnosed with Cerebral Venous Sinus Thrombosis or (CVST).  He had asked me if I would give my explanation of what it is and if it was something he should be worried about.  His doctor had exCSVTplained it but he was still a bit foggy regarding the diagnosis.  Well, after looking into it from the clinical perspective, I realized that it was a pretty big deal and in some cases may be fatal.  I researched multiple sources to gather credible information and when it all came down to brass tacks, I found that the Wikipedia explanation had done a pretty dog-gone good job of summarizing CSVT.  So, with all credit given to them for most of this article and a link back to their website, here it is.

I have personally responded and treated many different types of head injuries as a paramedic but had not researched this problem to this level.  Then, shortly after receiving this question, I read that  Secretary of State, Hillary Clinton was diagnosed and hospitalized with the very same problem secondary to her head injury!  Ironic.   So, I thought to myself, if two people experienced this problem secondary to a common traumatic head injury(concussion), there may be more with the same question.

Here’s my trimmed-down version of what it is, what it’s symptoms are, how to determine if it is truly CSVT and then what a person may want to do if they think they may be suffering from such a complication.  So let’s dig into some of the questions you may have!  P.S.  You’ll notice there are more links then usual in this article.  The topic is so complex and has so many different facets I thought it wise to allow you to do some of your own information mining and hope the links make it easier.

Q:  What is a cerebral venous sinus thrombosis anyway?

A:  A CVST is the presence of thrombosis (a blood clot) in the dural venous sinuses, which drain blood from the brain. 

Q:  What causes a CVST?

A:  There can be many causes of CVST.  Here is a few I included:

Q:  How might I know if I have a CVST?

A: Headache that may worsen over the period of several days, but may also develop suddenly.  Strangely the headache may be the only symptom of cerebral venous sinus thrombosis.  Stroke, 40% of all patients have seizures, Common symptoms in the elderly with this condition are otherwise unexplained changes in mental status and a depressed level of consciousness.  The pressure around the brain may rise, causing papilledema (swelling of the optic disc) which may be experienced as visual problems.  In severely raised intracranial pressure, the level of consciousness is decreased, the blood pressure rises, the heart rate falls.  This is a common symptom found in closed head injuries which makes sense as the mechanism is very similar.

Q:  How will the doctor know if this is what I have?

A:  The most commonly used tests are computed tomography (CT) and magnetic resonance imaging (MRI), both using various types of radiocontrast to perform a venogram and  visualise the veins around the brain

Q:  How is a CVST treated and cured?

A: Treatment is with anticoagulants (medication that suppresses blood clotting), and rarely thrombolysis (enzymatic destruction of the blood clot). Given that there is usually an underlying cause for the disease, tests may be performed to look for these. The disease may be complicated by raised intracranial pressure, which may warrant surgical intervention such as the placement of a shunt.

AmbulanceQ:  Can this be serious?

A:  Yes.  Like any illness or injury that causes a problem with the circulation of oxygenated blood to our tissues, this type of problem can be very dangerous if left untreated.  It also runs a risk of complication in that it raises the intracranial pressures which can act similar to a closed head injury and this too can cause severe injury or death.  If a person has any of the symptoms listed above, they should be seen as soon as possible to rule out this potentially life threatening disorder.  If a person is reacting with decreased level of consciousness, or any type of life threatening complications, activation of Emergency Medical Services or 911 should be immediate with life saving or time buying intervention given.

 

I hope this helps and keep well!

When Is It Safe To Return To Work or Sport After A Concussion?

Hello Everyone,

I had a person email this question and I thought it may be a good refresher for everyone on a very common accident and injury that effects many different age groups and many different people.

Below is the question and the answer follows below that.

Dear Roy,

I had an injury yesterday playing baseball I ran into another player. I don’t really remember what happened.  I was told I hit my head on his chin and on the way down, my chin hit his knee, and then hit my head on the ground. I was knocked out. When I woke,  I didn’t know what happened and could not move or talk for about a minute.  Then, when I went to get up, my legs collapsed.   So I went to the emergency room for  a CT scan.  No bleeding to the brain,  but had an extreme headache.  Now the next day,  head still hurts and my neck is sore but not as bad. the ER doc said everything looked fine, but could not really say if I have a concussion or not.  He said I have the “symptoms”.  I guess my question is,  when should I go back to work?  The doc only took me off for a day but I am still in pain.

Hello J—-,

Concussions can be very tricky. They may not show up on CT or Xray and you can really feel lousy for a while after the initial accident. If you don’t feel capable of returning to work, it’s always best to allow your body the ample time required to heal prior to putting your body back in a stressful situation. However, that’s the perfect case scenario. It’s pretty common that those of us who work, may have to return to work prior to feeling 100%. If this is the case and you cannot get your doctor to write a letter for additional recovery days for your employer, make sure you watch your signs and symptoms and listen to your body. If you become dizzy, nauseated, develop a headache etc., these can lingering signs of a concussion but may not be serious enough for you to be hospitalized. But if you handle heavy equipment or must be at your best to stay safe, keep others safe, or do the level of job required of you, this should probably be communicated to your professional health care provider and see if an extra bit of recovery time could be allowed.

It’s never any fun getting a “Konk On The Melon” and even less fun dealing with the lingering side effects while duty is calling the patient back to work.

Keep an eye on your symptoms and as most any health care provider would tell you, if your symptoms worsen, you become more painful and not less painful over time, if you have numbness, tingling, have a seizure, headache increases, get more dizzy not less dizzy or have a decreased level of consciousness, 911 should be called and you should be seen in the Emergency Room.

Other wise, if the symptoms don’t get worse but get better though are still lingering a few days, it may be within normal recovery expectations and you simply need to take it easy and allow yourself to recover.  If you are ever in doubt, don’t hesitate to contact your medical professional and let them know what your symptoms are and see if they want to reassess the situation.

I found a well laid out guideline for definitions and signs and symptoms from a website and I’ll pass the information on to you along with the link for credit to the referenced website.

Sports Concussion

It’s more than just a bump on the head

MYTHS about sports concussion…

1. Concussion is a minor brain injury with no long-term effects

2. If you weren’t knocked out, then you didn’t have a concussion

3. Having multiple concussions is common in sports and no cause for concern

4. Symptoms of a sports concussion will always clear up, usually in a few days

5. If there’s no visible injury, everything’s okay

6. You should play through the pain—get back in the game!

FACTS about sports concussion…

1. Twenty percent of all concussions are sports-related

2. A concussion doesn’t always knock you out

3. Having one concussion increases your chances of having another

4. Symptoms of a concussion can last hours, days, weeks, months, or indefinitely

5. Concussion can cause disability affecting school, work, and social life

6. Returning to contact or collision sports before you have completely recovered from a concussion may lead to more serious injury and can increase your chances of long-term problems

What is a concussion?

Concussion is a mild traumatic brain injury that occurs when a blow or jolt to the head disrupts the normal functioning of the brain. Some athletes lose consciousness after a concussion but others are just dazed or confused. Concussion is usually caused by a blow to the head, but can also occur due to whiplash.

How can you tell when an athlete or person gets a concussion?

Sometimes, but not always, the athlete will be knocked out. In cases where there is no obvious loss of consciousness, the athlete may appear to be confused or disoriented (such as running in the wrong direction), and may not remember things that happened before or after the concussion, such as what period it is or the score of the game. Often, the athlete will describe some symptoms of a concussion, such as headache, dizziness, nausea, or blurred vision. It is also common for athletes to describe feeling “fuzzy” or “foggy” after concussion, and to have problems with balance or coordination. For this reason, and also because symptoms can sometimes worsen rather than improve, careful observation of the athlete after concussion is especially important.

What is post-concussion syndrome?

Post-concussion syndrome is a term that describes the physical, cognitive, and emotional symptoms that are caused by concussion and which can last for a varying amount of time after injury. Some symptoms show up right away, but others may not appear or be noticed until the next day or even later. Likewise, some symptoms might resolve fairly quickly, but others—especially fatigue—can persist much longer. The number and severity of symptoms, the speed of recovery, and the impact of symptoms on day-to-day functioning will be different for each athlete.

Physical Symptoms…

* headache
* neck pain
* nausea
* lack of energy and constantly feeling physically and mentally tired
* dizziness, light-headedness, and a loss of balance
* blurred or double vision and sensitivity to light
* increased sensitivity to sounds
* ringing in the ears
* loss of sense of taste and smell
* change in sleep pattern especially waking up a lot at night

Social and Emotional Symptoms…

* mood changes including irritability, anxiousness, and tearfulness
* decreased motivation
* easily overwhelmed
* more impulsive and disinhibited
* withdrawn and wanting to avoid social situations

Cognitive Symptoms…

* feeling ‘dazed’ or ‘foggy’
* difficulty concentrating and paying attention
* trouble with learning and memory (especially for recent events)
* problems with word-finding and putting thoughts into words
* easily confused and loses track of things
* slower in thinking, acting, reading, and speaking
* easily distracted
* trouble doing more than one thing at a time
* lack of organization in everyday tasks

How long does it take to get better?

Most people do recover completely from a concussion, usually in a matter of days. However, it can take up to a year or longer for some athletes to recover, and in some cases the symptoms won’t go away. Recovery may be slower in those who have already had one or more concussions, and in those who have a history of learning disability or attention disorder.

When it is safe to return to play after concussion?

There are several guidelines for return to work/play after concussion.  All of these share some common principles:

1. An athlete who has suffered a concussion should be removed from competition immediately and monitored for post-concussion symptoms

2. An athlete should not return to play before he or she is completely symptom-free at rest and after exertion for a specified period of time, which varies based on the athlete’s history and the severity of the concussion.

3. Athletes who have a history of one or more previous concussions should be treated more cautiously (not returned to play as quickly) than those who have suffered their first concussion

4. When in doubt, sit them out!

How can you tell when an athlete is symptom free?

An athlete should only return to competition when it is clear that there are no lingering symptoms of concussion. Unfortunately, because concussion is an invisible injury, and because athletes may minimize or not recognize persistent post-concussion, symptoms, this can be a tricky matter. Also, symptoms may sometimes go away, only to come back after physical or mental exertion.

Most often, return to play decisions are made without the benefit of neuropsychological testing and are based on observation and player report of symptoms. Neuropsychological testing provides the coach or team physician with information that can help to take the guesswork out of concussion management and return-to-play decisions. Using a battery of tests of memory, reaction time & processing speed, we can provide specific information regarding the severity of injury and a standard for evaluating recovery from injury. It is of benefit for athletes to receive baseline assessment prior to or at the beginning of the athletic season to allow for within-subjects analysis of scores following an injury.

I hope this helps J—- and I hope you feel better real soon.

Thanks for the question.

Best Wishes,

Coaching Sports, Injuries and Liability

BaseballI would like to pass on a quick informational about injuries and liability when it comes to coaching and organized sports.   I found the following outline very helpful when it came to the part about how to put a proactive risk management policy together.  Whether your sports organization is volunteer or paid, a healthy risk management program is always wise.

The following is specifically on how to deal with training, injuries/illnesses and return to play, but the website has a lot of really great advice.  I’ve included the link below or you can click on the hyperlink in this paragraph.

Sport Specific Techniques – Coaches should always follow the accepted practices for teaching sport specific techniques. Certain drills and other methods that are standard for each sport should be followed. Coaches should be involved in continuing education to learn about the advances of teaching techniques. It is especially important that instructions key in on the more hazardous areas of a particular sport such as avoiding a wild pitch, tackling techniques, etc.

Safety Rules and Procedures – Safety rules and procedures should be reviewed before and during every practice and game. They require constant reinforcement with special emphasis on the purpose and intent of the rules and the types of injuries they are meant to prevent. Any rule changes dealing with safety should be reviewed with all coaches during the pre-season with an emphasis on the types of injuries they are meant to prevent.

Sports Injury Care

Sports injury care consists of two basic elements – prevention and recognition/treatment. Youth sports administrators (RMO’s and Coaches) must understand the importance of both elements.

1) Prevention – Consists of pre-participation screening, strength training, conditioning, and awareness of the nature, cause, and mechanism of sport specific injuries.

2) Recognition and Treatment – Once the coach realizes that the injury has occurred, the magnitude must be assessed and appropriate care initiated.

Consent to Treatment – Health care providers can’t lawfully render treatment to a patient without consent. When a minor is involved, consent must be obtained form a parent or legal guardian. In life threatening situations, the law assumes that consent is given. However, once the patient has stabilized, consent must be obtained for further care. Having a “consent form” on file my provide some protection against a parent’s claim that emergency care was not authorized and can help to overcome apprehensions of health care providers about rendering treatment before lawful consent is obtained. Also, such consent forms should list if the athlete is allergic to any medications and should specify who should be notified in the event of an emergency.

First Aid and CPR – All coaches should be certified in basic first aid and in CPR. The coach should not exceed the scope of his training in administering first aid. The purpose of first aid is merely to stabilize the situation by preventing it from worsening. Once the situation has been stabilized, all other treatment should be provided by a doctor.

Emergency Medical Plan – Should be developed with the assistance of local doctors, hospitals, and EMS. The Emergency Medical Plan must be tailored differently for each community because of differing availability, response times, etc. Coaches should be specifically trained how to activate the Emergency Medical Plan.

The plan should be in writing and readily available and should cover the following elements:

  • Who calls EMS?
  • Who stays with injured athlete?
  • Where is nearest phone?
  • What phone number to call?
  • Where is the nearest treatment facility?
  • Where is the ‘consent to treat’ form?
  • Does the athlete have any medicine allergies?
  • How to notify parents?
  • How to initiate crowd control?
  • Who meets EMS and the guides them to the injured athlete?
  • Who accompanies the injured athlete for treatment?
  • Who supervises the team?
  • Who provides proof of insurance?

An alternative Emergency Medical Plan should be formulated when traveling to other facilities.

Return To Play – Once an athlete has suffered an injury, the decision regarding the appropriate time to return to play should be made by a doctor. The coach should not put pressure on an athlete to return too early and the instructions of the doctor should always be honored.
