Thrombosis, which today means the blockage of a blood vessel with a blood clot (thrombus), is a word meaning “plug” in ancient Greek. Deep Vein Thrombosis (DVT) is a blockage in deep veins caused by blood clotting.
The frequency of this disease, which is most commonly seen in the leg veins, is 1-2 per 1000. This disease, which is generally seen at the age of 40-50 years and later, is rare but can also be seen in young people.
In which situations is DVT seen?
This disease, also known as economy class syndrome, is a common health problem on long journeys. Flights that are inactive for more than 5-6 hours are one of the most important risk factors. In addition, long periods of inactivity (such as after orthopedic treatments, intensive care processes or major surgical interventions), cancer itself or chemotherapy used in cancer treatment, pregnancy and birth control pill use in women, genetic bleeding-coagulation diseases (protein CS deficiency, FV) such as the Leiden mutation) are among the factors that increase the risk of DVT.
D What symptoms are seen in a person who has had VT?
The obstruction may start from the veins below or above the knee and progress to the main vein (Vena Cava Inferior) in the abdomen. The closer the level of the involved vessel to the heart, the more severe the clinical manifestations. Complaints such as tension and stiffness in the legs, swelling, pain, warming and discoloration are seen in people who have had DVT.
How is DVT diagnosed?
Doppler ultrasonography; It is a method based on the principle of showing veins and their contents using sound waves. While a definitive diagnosis can be made in leg veins, other methods may be required for definitive diagnosis in inguinal and abdominal veins.
Other than Doppler ultrasonography, examinations such as venography, medicated computed tomography or MRI are imaging methods used in cases where the diagnosis cannot be made or additional examinations are required.
What are the complications of DVT?
There are two complications of DVT, one in the early period and the other in the late period.
Pulmonary embolism is when the clot in the vein breaks off from where it is and throws it into the pulmonary artery in the early period. The symptoms of this disease, which ranks first among preventable hospital deaths, vary according to the size and prevalence of the clot piece(s) causing the blockage.
The complication that may develop in the late period is the post-thrombotic syndrome (PTS). PTS, which is a condition seen in almost half of the patients who have undergone DVT and are not treated appropriately, is a table with complaints such as swelling in the legs, pain, and skin thickening, but it is more common in high level (thigh and abdominal DVTs) involvements.
I wish you a healthy week and pleasant flights.
