iliac and femoral vein thrombosis

Thrombosis is suitable for extensive thrombosis of the iliac crest and femoral vein. (Clinical manifestations of severe swelling, cyanosis, chills, severe pain in the limbs, severe cases of chills, gangrene and even shock, and mild edema of the affected limbs). Surgery must be performed in the early stage of the disease, about 12 to 48 hours, before the thrombus has been adhered to the vein wall and the distal vein has not been extensively thrombosis. Treating diseases: thrombosis Indication Thrombosis is suitable for extensive thrombosis of the iliac crest and femoral vein. (Clinical manifestations of severe swelling, cyanosis, chills, severe pain in the limbs, severe cases of chills, gangrene and even shock, and mild edema of the affected limbs). Surgery must be performed in the early stage of the disease, about 12 to 48 hours, before the thrombus has been adhered to the vein wall and the distal vein has not been extensively thrombosis. Preoperative preparation 1. For severe cases of extensive hernia and femoral vein thrombosis, blood transfusion, infusion and other therapies should be used first to treat shock. 2. Apply anticoagulant therapy to prevent the growth of blood clots. 3. Appropriate application of analgesics and antispasmodic drugs. 4. Prepare for blood transfusion during surgery. 5. The entire diseased limb and abdominal skin should be disinfected. Surgical procedure 1. Incision, revealed: a longitudinal incision from the midpoint of the inguinal ligament, extending approximately 10 cm down the inner edge of the sartorius muscle. Cut the deep fascia, you can see the edema swelling of the embolization site, thickening of the wall, whitish and tough. The superficial femoral artery across the femoral vein is cut and ligated to facilitate the visualization of the femoral vein. The extravascular sheath is cut, the femoral artery and femoral vein are carefully separated, and the femoral artery is pulled outward along with the sartorius muscle. 2. Control the blood vessels: The proximal and distal ends of the femoral vein and their branches are each wrapped around a fine gauze to control bleeding. 3. Incision of the vein and removal of the thrombus: first adjust the operating table to raise the upper body of the patient. The blood flow of the vein can be controlled by lifting the gauze band of the femoral vein and its branches upwards. After the femoral vein wall was longitudinally incised at the embolization site for 1 to 1.5 cm length, the black thrombus was removed or removed with a toothless tendon. At the same time, the anesthesiologist can intravenously inject 50 mg of heparin from the upper extremity. Combined with the use of suction and large, calf massage, the embolization of the distal segment of the vein is removed. With the help of the patient's abdomen forced to squeeze, the suction tube is used to remove the thrombus near the heart of the vein until the blood flow is smooth. Finally, the venous lumen is flushed with light heparin to prevent residual lungs from causing the lungs. 4. Suture incision: The incision is made by a thin wire for continuous eversion suture. Before ligation of the last stitch, the blood must be vented.
