D.V.T - THE SILENT KILLER

/>
This week I assigned myself the task to make a presentation about Deep Venous Thrombosis (DVT) to my colleagues in Chaaria. Its a silent killer that kills in seconds. It reminds me of the death of a popular TV personality who was found dead on her bathroom floor sometime in September. Rumors went round about the possibility of poisoning or bathroom accident because she was as fit as a fiddle but autopsy made a conclusion that she had succumbed to embolism from a DVT.

DVT is the formation of a clot in the deep veins of the limbs especially in the legs. If the clot dislodges( what we call embolism) and goes to the lungs, it causes death in seconds. I have atleast two DVT patients in the wards every month. A few succumb to embolism because they present to the hospital with breathlessness when it is too late. I have had to force some of the patients to be admitted in the hospital despite resistance. I confront them and tell them point blank that I do not want to be responsible for their deaths. It's one condition of which I put my foot down and refuse discharge against medical advice.

So how does it present? How do you know that you could be suffering from DVT? It classically starts as swelling of one leg which could be painful especially at the calf. The leg might get warm and reddened with time. Superficial veins sometimes get visible and in the extreme cases, the limb might get gangrenous or start turning blue. What are the risk factors for DVT? These are generally categorized into factors that cause Stasis of blood in the limbs, increased clotting of blood in the body and injury to major blood vessels. These include being immobile for long hours or days(especially in bedridden patients or long distance travellers), cancers which predipose to hypercoagulation of blood, trauma or fractures of limbs, recent abdomino-pelvic surgeries (e.g hysterectomy, prostatectomy, caesarean sections etc), recent bone surgeries(orthopedic surgeries), use of estrogen containing contraceptive pills, cannulation of major blood vessels of the body especially in dialysis patients,patients with diseases like nephrotic syndrome, pregnancy e.t.c. The list is endless.

Diagnosis requires color duplex ultrasound of the affected limb. This can be combined with other more complex investigations. Treatment requires compulsory hospitalization for anticoagulation and strict follow up in the months that follow. ( I will not bore you with the specific treatment modalities). So if you develop swelling of one leg no matter how innocent it looks, run to the hospital before death runs to you. It's not proper to ignore. We should also avoid sitting or lying down for long hours. This targets everybody including those who sit in offices for long hours, long distance travellers or frequent air-travellers. Those who are in hospital and having undergone surgeries should learn to ambulate early and walk around. How many times have we heard of stable patients collapsing on discharge or collapsing in the toilet just before discharge? (Why is the toilet the most common place for death in DVT patients? Food for thought!!!!). Or how many healthy people have we heard found dead after a perfectly normal daily activity.

Let's be careful. Let's spread the information and learn to take any swelling of one limb seriously. Let us also get active. That simple standing from your chair and going to the dispenser in the office could save you from death. The frequent air travellers should learn to walk to and fro the aeroplane isles at-least 3 times in the flight (DVT is also called the 'pilots disease'). I hope that this week's post will help someone out there. Have a great start to February!!!! BEWARE!!!!! Let's be alert.
