Diagnostic tests for stenosis of a renal artery in Schoen Clinic Duesseldorf

About the department

The Department of Vascular Surgery and Angiology at the Schoen Clinic Duesseldorf offers all the possibilities of modern medicine in the areas of its competence. The medical facility provides conservative, endovascular, and classical surgical treatment of vascular diseases, including rare and particularly complex pathologies of the arteries, veins, and lymphatic vessels. The department first opened its doors to patients in 1997, becoming one of the first health facilities of this kind in Germany. Today, the department has an excellent reputation and admits patients from Germany and many other countries around the world. The team of the department's doctors is especially interested in the treatment of peripheral occlusive arterial disease, aortic aneurysms, carotid artery stenosis, varicose veins, superficial venous thrombosis, and diabetic foot syndrome. Angiologists and vascular surgeons jointly consider the patient's clinical case and prescribe the optimal treatment, with conservative or endovascular treatment being performed if possible. The department has an in-house catheterization laboratory for endovascular interventions and an operating room for hybrid interventions (such operations combine endovascular and classical surgical techniques). The department has 30 beds for inpatients, while minor endovascular surgical procedures are performed on an outpatient basis. The Head Physician of the department is Dr. med. Udo Huberts.

The department's doctors regularly treat peripheral occlusive arterial disease. This pathology causes complete blockage or narrowing of the lower extremity arteries (rarely the upper limbs may be affected) due to atherosclerosis, which provokes impaired blood circulation and insufficient blood supply to the tissues in the lower extremities. The specialists at the medical facility successfully use conservative and surgical methods for the treatment of peripheral occlusive arterial disease. In the early stages, doctors recommend patients make lifestyle modifications, including a healthy diet, weight loss (in cases of excess body weight), regular physical activity, smoking cessation, etc. Drug therapy is also part of the treatment process. It mostly includes platelet aggregation inhibitors (drugs that prevent the formation of blood clots) and statins (cholesterol-lowering drugs). As peripheral occlusive arterial disease progresses, patients may experience pain while walking. In such cases, clinicians offer them specialized exercise programs for pain relief. The second-line treatment is balloon dilatation with stent implantation, thrombus aspiration, or thrombolysis. In cases where patients experience pain in the lower extremities even at rest, effective treatment results may only be achieved through surgery. The department's vascular surgeons perform thromboendarterectomy, affected artery prosthetic repair, and bypass surgery. The optimal type of surgical procedure for the patient is determined on an individual basis.

The department's specialists excel in treating abdominal and thoracic aortic aneurysms. They perform more than 1,500 interventions of this kind every year. The key focus is on minimally invasive surgery using innovative stent grafts, which are delivered to the pathological focus under imaging guidance through a puncture in the inguinal artery. Before the operation, vascular surgeons plan each stage of the intervention with the help of special computerized programs, thereby ensuring precise positioning of the stent graft. The duration of a hospital stay after endovascular treatment of aneurysms is 4-6 days. The patient is verticalized on the second day after surgery. In addition, there is no need for specialized rehabilitation. The department's physicians also perform classical open operations for aneurysms. For example, if the aneurysm is localized in close proximity to the heart, the patient is indicated for open surgery. It is performed by both vascular and cardiac surgeons.

Another important area of competence of the department's team of doctors is the provision of medical care for patients with varicose veins. Many people mistakenly believe that varicose veins are only an aesthetic problem, but the pathology also carries serious health risks. The disease may provoke the formation of blood clots, the development of chronic venous insufficiency, thrombophlebitis, trophic ulcers, and other severe complications. Conservative treatment for varicose veins involves wearing compression stockings, therapeutic exercises, and massage. In cases of severe symptoms and a high risk of complications, vascular surgeons consider surgical treatment options such as stripping, phlebectomy, mini-phlebectomy, radiofrequency ablation, endovenous laser therapy, or sclerotherapy. Surgical treatment for varicose veins is also performed in cases where patients do not suffer from the symptoms of the disease but are concerned about the aesthetic aspect of the problem. In most cases, surgical procedures for varicose veins are performed on an outpatient basis under local anesthesia.
