Be careful about venous thrombosis after childbirth

　　Postpartum Thromboembolic phlebitis is a serious complication that is prone to occur during pregnancy, intrapartum and postpartum periods. The incidence rate during the puerperium is 49 times higher than during non-pregnancy.

　　The reason for this disease is that most patients have reduced lower limb activity after surgery, resulting in venous thrombosis. Thrombus will block the venous return of the lower limbs, causing swelling, thickening, pain, and inability to move the lower limbs. Over time, it can also form ulcers that will not heal for a long time. Once the thrombus breaks free and flows back to the lungs along the vena cava, it can also cause pulmonary embolism, leading to hypotension, syncope, heart failure, etc.

　　The causes of venous thrombosis include slow blood flow (such as sitting for a long time), damage to the vein wall, hypercoagulable state (such as surgery, advanced age, tumors), obesity, diabetes, and susceptibility genes.

　　Prevention and treatment measures for postpartum thrombophlebitis include encouraging maternal activity and anticoagulation therapy as well as surgical treatment.

　　Encourage pregnant women to be more active . Pregnant women should do some housework or take a walk even before giving birth to reduce blood stasis and blood vessel compression. The first week after delivery is a period when embolism is common, and mothers should be encouraged to get out of bed early and move around. After the operation, the mother should turn over in bed and do activities such as stretching and flexing her limbs as soon as possible after the operation.

　　anticoagulant therapy . Heparin is the preferred anticoagulant drug. Low-dose heparin can inhibit the formation of thrombus. When thrombus has formed, high-dose heparin is needed to neutralize thromboxane to prevent further increase of thrombus.

　　surgical treatment . It is suitable for patients with severe embolism or large vein embolism that fails conservative treatment. Surgical methods include venotomy and thrombectomy, venous shunting, embolized segment vein grafting and interventional thrombectomy under radiography.
