Vein Problems & How To Treat Them

August 16, 2019

Deep Vein Thrombosis

Deep Vein Thrombosis (DVT) is a condition that occurs when a blood clot forms in the veins located
deep inside the body. This clot blocks the vein and as a result the blood flow to this affected part is also
blocked. Typically, it occurs in thigh or leg (usually one side) but can also occur in other parts of the
body. According to statistics around 60,000-100,000 people die each year due to DVT/PE in the United
States. (1)(2)

Symptoms

DVT is characterized by symptoms like:

  • Swelling of the extremities
  • Unexplained Pain
  • Warm skin area as compared to other parts
  • Redness around the affected area. (3)
  • Sometimes DVT occurs without any symptom. If sign and symptoms of DVT appear, a medical doctor
  • should be contacted immediately.

Risk Factors

The risk factors for DVT are:

  • Age; with an increased risk after 40 years
  • Certain medication like use of birth control pills and Hormone Replacement Therapy (HRT)
  • Pregnancy- as blood clots easily during pregnancy
  • Obesity
  • Certain diseases and their treatments like cancer (chemotherapy), heart failure, injury, Kidney
    disease
  • Family history of DVT
  • Immobility especially after surgery and sitting for longer durations for e.g. when traveling via
    plane, car or train (4)

Diagnosis of DVT

DVT can be diagnosed by using specialized tests. The most common method used to detect DVT is a D-
dimer blood test. This test measures a substance released in the blood when the clots break up.
However, the use of D-dimer test in elderly patients has not been widely recognized.
Ultrasound scan is used as a standard imaging test. Sound waves in the ultrasound are used to produce
the image of the veins so that the doctor can see the blood flow. The flow of blood is disturbed or slow
when a clot is present. (4)

Vein Treatment options

Medication
Blood thinning agents is usually the first choice of therapy for acute Deep Vein Thrombosis. Heparin is a
frequent blood thinning agent usually given to the patients who are hospitalized. The use of blood
thinning agents is associated with a risk of bleeding and therefore, patients should be carefully
monitored.

Thrombolysis

Patients who do not respond to blood thinning agents are then treated with thrombolytic medication
such as streptokinase which breaks down the clots (5) .

Filters

Filters placed in the large abdominal vein (vena cava) are also a choice of treatment in those patients for
whom blood thinning medication is not advised. Hence, the choice of treatment therapy may vary from
case to case. (3)
Complications

Pulmonary embolism

The most common complication of DVT is Pulmonary embolism (PE). It occurs when the blood clot from
the deep vein moves to the lungs and blocks the blood vessels. Patient develops difficulty in breathing,
chest pain, irregular heartbeat and coughing up blood. PE is a medical emergency and should be
handled immediately. (6)

Post thrombotic syndrome

Another complication of DVT is Post thrombotic syndrome. In this state the valves in the veins are
affected by the clotting resulting in high pressure in the veins. Symptoms include swelling, itching,
discoloration and ulcer formation of the affected area (7) .

Recurrence

DVT is a chronic condition and one third of the patients have recurrence after the first event. Old age
and obesity are associated with highest recurrence. (8)

Prevention of DVT

  • Lifestyle measures like regular exercise, maintaining healthy weight and quitting to smoke play
    an important role in the prevention of DVT.
  • The use of compression stockings especially in hospital admitted patients greatly reduces the
    risk of DVT. Women at risk of developing DVT who need to have a surgery should stop using
    birth control pills before admission to the hospital.
  • During long distance journeys by train car or plane, exercise at regular intervals like moving legs
    and foot and use of compression stockings is advised.
  • Intermittent pneumatic compressions are also used in inpatients to prevent DVT. (9, 10)
