Today is the 15th
" United Nations Diabetes Day " .
This year's theme is
"Diabetes Health Management for Everyone".
Lao Wang (pseudonym), who has a history of diabetes for more than 20 years, suffered a wound on his toe due to a corn surgery, and the ulcer became more and more serious. When he went to the hospital for examination, it was found that the blood vessels in his lower limbs were severely occluded and the blood supply was insufficient. In the end, the severely ulcerated toe had to be amputated.
Fortunately, after treatment, the blood vessels in Lao Wang's lower limbs became unblocked again, avoiding the risk of amputation and preserving 80% of the foot function.
One-time repair of corns led to big problems
Twenty years ago, Lao Wang was diagnosed with diabetes. At first, he took anti-diabetic drugs on time, and his blood sugar control was satisfactory. But then he relaxed his "vigilance". Not only did he not monitor his blood sugar regularly and take anti-diabetic drugs irregularly, he also completely relaxed about his diet.
A few years ago, Lao Wang began to experience symptoms of intermittent claudication . His legs and feet hurt after walking for a while and he had to rest before he could continue walking. He thought it was because he was older and didn't pay much attention. Half a year ago, he had a "corn" on the little toe of his right foot. After it was repaired outside, the wound could not heal and ulcerated. After going to the local hospital for debridement and applying medicine, not only did it not get better, but it lasted for half a year. The ulcer grew from a small opening to a "big hole" and the pain was unbearable.
He came to the outpatient clinic of Professor Wang Haiyang of the Vascular Surgery Department of the First Affiliated Hospital of Guangzhou Medical University. The doctor gently opened the gauze wrapped around his rotten foot. A stench hit his nose, and yellow pus flowed out of the wound. After an ultrasound examination of the arteries of the lower limbs, the doctor found that the blood vessels in Lao Wang's lower limb where the ulcer was ulcerated had been severely occluded. It was precisely because of the severe occlusion of the blood vessels and insufficient blood supply that the ulcer on his foot was difficult to heal.
The doctor first performed debridement and anti-infection treatment for Lao Wang, and then used minimally invasive technology to cut a small incision in the blocked blood vessel, clean out the "garbage" accumulated inside, and restore smooth flow of blood vessels.
Unfortunately, the condition lasted for too long, and Lao Wang’s badly ulcerated toe had to be amputated. Fortunately, it did not affect his normal foot function. "If it is more serious, the entire foot may not be saved." The doctor said.
Infrared detection is an early warning of vascular disease
"Diabetes is a chronic disease. Patients must fully realize the importance of controlling blood sugar. cannot stop taking medication at will. must follow the guidance of professional doctors and seek medical treatment in time when problems are found." Wang Haiyang said that foot ulcers are one of the main complications of diabetes. If blood sugar is poorly controlled for a long time, diabetic patients are more likely to aggravate arterial sclerosis, thickening of blood vessel walls, and reduced elasticity of lower limb arteries. They are also prone to the formation of thrombosis, causing vascular occlusion in the lower limbs, damage to extremity nerves, and tissue pathological changes in the lower limbs.
How can diabetics detect early the presence of vascular disease in the lower extremities? Wang Haiyang said that the hospital's vascular surgery department has applied infrared thermal imaging detection technology to the field of vascular screening.
Infrared detection has high sensitivity to body surface temperature and can play an early warning role in vascular disease screening
"This detection technology was developed by the team of Academician Zhong Nanshan. It has high sensitivity to body surface temperature and can play an early warning role in vascular disease screening. It is non-invasive and non-radiative." Wang Haiyang recommended that patients with a history of diabetes undergo regular vascular screening to be alert to vascular disease. If the blood flow in the arteries of the lower limbs is smooth and the blood sugar is under stable control, it is recommended to do vascular screening once or twice a year to detect potential vascular risks and intervene early.
Do your daily homework and stay away from Diabetic foot
In addition to monitoring and controlling blood sugar and doing relevant screenings regularly, diabetic patients should also take good care of their feet in daily life and clean them well to avoid secondary infections such as paronychia and athlete's foot, as well as damage and lesions on their feet.Wang Haiyang reminds you to pay attention to the following points every day:
1. Check your feet carefully every day for minor injuries, such as scratches, lacerations, blisters, etc., and pay special attention to checking the toe seams and soles;
2. Wear loose, wide, soft cloth shoes or breathable leather shoes, avoid sandals or high heels; keep the shoes dry, and rotate several pairs of shoes at the same time;
3. Wash your feet with warm water and neutral soap every day. The water temperature should not exceed 40°C. Do not scald your feet with hot water;
4. In addition to keeping your feet breathable and dry, you must also prevent athlete's foot and frostbite. Once you find athlete's foot or frostbite, seek medical treatment as soon as possible;
5. Be careful not to hurt your feet when trimming toenails and corns.
If diabetic patients develop lower limb ulcers, infection, or even skin blackening (gangrene), they must seek help from a regular vascular surgeon in a timely manner to avoid delaying the best opportunity for treatment.
