The expert said, Blood clot after knee surgery is very likely to occur. According to the specialist heart and cardiovascular, Dr. RWM Kaligis, about 40 to 60 percent of patients undergoing major orthopedic surgery, such as joint replacement surgery of the hip (total hip replacement/THR) or total knee joint surgery, will experience blood clots (VTE) if they do not receive preventive measure.
Venous thromboembolism or VTE is the third most common cardiovascular disease after heart disease and stroke. Unlike the two diseases, VTE usually occurs after orthopedic surgery (Knee surgery).
“Preventive action is important, especially for patients who have high risk factors,” said Kaligis. Described by him, there are three main factors triggering VTE, IE there is injury to the blood vessels, slowing blood flow and blood clotting their talent (hyper koagulitas).
Orthopedic surgery patients have all three of those drivers, particularly because blood flow is stuck in the wound, an injury to the blood vessel walls due to venous and pulled muscles during surgery and blood flow is static during an anesthetic.
In addition to patients post orthopedic surgery, VTE can also occur due to blunt impact, for example on accident victims, the elderly, less mobile, or paralyzed patients.
VTE can occur in the form of deep venous thrombosis (deep vein thrombosis / DVT), usually occurs in the legs. VTE can also occur in the so-called pulmonary embolism pulmonary embolism / PE. This happens because the blood clot that broke borne follow thus blocking blood flow circulation. Besides damaging the lungs and vital organs, can also be fatal PE, namely death.
VTE is often clinically unnoticed and difficult to diagnose. “The symptoms that occur in DVT or PE is similar to other conditions, making diagnosis somewhat difficult,” said Kaligis.
Symptoms of DVT include leg pain, pain when touched, cramps, skin redness, and swelling in the leg. While PE has symptoms suddenly can not breathe, coughing up blood, chest pain, or fainting. “PE can quickly become fatal,” said a doctor from the Heart Hospital Harapan Kita.
However, patients do not need to worry perform orthopedic surgery. Operation remains to be done for elderly patients to improve their quality of life. “Rather than can not walk, it’s better done THR surgery or knee joint,” said Dr. Dr. Andri Lubis, SpOT of RSCM Jakarta.
According to Andri, most patients suffering from orthopedic postoperative VTE after returning home. Therefore, to prevent VTE, patients with a high risk should be given preventive therapy of blood clots, either in the form of injection for inpatients, or oral tablets for postoperative patients who have already gone home.
