Question
What are the regional ischemic symptoms of thromboangiitis obliterans during the brain edema stage?
Answer
During the regional brain edema stage of thromboangiitis obliterans, patients often experience symptoms such as regional coldness, tingling, swelling, pain, and limping in the foot area. These symptoms usually subside after rest. Moreover, these patients are generally younger, with most being under 50 years old, and many have a smoking habit. They often accompany other diseases such as hypertension, hyperlipidemia, coronary heart disease, atherosclerosis, or diabetes. The inflamed arteries are usually larger arteries, such as the abdominal aorta bifurcation, iliac artery, femoral artery, or tibial artery, and rarely invade upper limb arteries. X-ray imaging can show irregular fibrosis shadows in the arteries. The symptoms differ from those of migratory thrombophlebitis.
