Professor Zhou Weimin's Team: A Case of Femoral Artery In-Stent Restenosis Treated with Dingkex Medical’s DKutting® LL Scoring Balloon

Patient Information

Basic Information:Male, 84 years old.

Chief Complaint:Left lower limb pain for more than 1 month.

History of Present Illness:The patient reported that more than a year ago, without obvious cause, swelling and pain appeared in the left lower limb, which was related to walking, accompanied by numbness in both lower limbs. The left lower limb could not dorsiflex. Then, the patient went to the local hospital for treatment. After conservative treatment with drugs such as promoting blood circulation and removing blood stasis, the condition did not improve. In March this year, the patient was hospitalized in our hospital, and relevant examinations such as CT were completed. The diagnosis was "lower extremity arteriosclerosis obliterans." The patient underwent "left lower extremity arteriography, femoral artery balloon dilation stent angioplasty." In the past month, the affected limb has experienced pain again. Today, the patient came to our hospital for treatment and was admitted to our department with "lower extremity arteriosclerosis obliterans" in the outpatient clinic. Since the onset of the disease, the patient's spirit, appetite, and sleep have been fine, and there has been no significant change in weight.

Past Medical History:Hypertension and diabetes for many years, self-reported blood pressure and blood sugar under control.

Physical Examination:The color of the left lower limb showed no obvious pallor, with scattered slight skin pigmentation visible. The distal phalanx of the fifth toe of the left foot was blackened; no skin ulceration, erythema, or swelling were observed elsewhere. Femoral artery pulses were palpable bilaterally, essentially symmetrical in strength and normal. Obvious pulsations were detected in the right popliteal artery, dorsalis pedis artery, and posterior tibial artery; no pulsations were detected in the left popliteal artery or dorsalis pedis artery. No significant abnormalities in skin sensation were noted in both lower limbs and feet, and limb motor function was essentially normal.

Follow-up

Discharge Status:

• The patient's general condition is acceptable, complaining of discomfort in the lower limbs after walking.Pain relief and significant improvement in the sensation of cold limbs.No headache, nausea, abdominal pain or other discomfort. Physical examination: no edema in both lower limbs, warm skin temperature, no numbness, palpable pulsation of bilateral femoral arteries, normal movement of both lower limbs, no obvious hematoma, pseudoaneurysm or other abnormalities at the puncture site.

• Long-term oral entericAspirin Tablets(1 tablet [100mg] once daily), in combination with oral administrationRivaroxaban(2.5mg, twice daily), be aware that the side effects of the medication may cause gastric ulcers or gastrointestinal bleeding, consult a gastroenterology department if necessary, and take oral acid-suppressing medication at the same time;

• Long-term oral administration of Simvastatin (one tablet per day, once daily); control triglycerides to less than 1.7 mmol/L, and regularly review blood lipids;

• Oral administration of Sarpogrelate Hydrochloride for at least one month (one tablet per dose, three times daily);

• If you feel unwell, stop taking the medicine promptly. The specific course of medication will depend on the changes in your condition.

Case Summary

Case Characteristics:Long-segment stenosis and occlusion within the superficial femoral artery stent.

Summary:In the treatment of lower limb arterial disease, the vessel preparation phase plays a crucial role. Although plain old balloon angioplasty (POBA) has been a commonly used treatment method, with the innovation in balloon technology,DK Medtech Scored BalloonStand Out in This Field with Advanced Design. Through its unique scoring design, it can expand the plaque inside blood vessels in an orderly manner, effectively avoiding the potential damage that may be caused by the uncontrolled expansion force of traditional balloons. This orderly expansion helps reduce elastic recoil of plaque or hyperplastic intimal tissue and lowers the risk and severity of flow-limiting dissections.
