Diagnostic tests for stenosis of a renal artery in Alfried Krupp Hospital in Essen-Ruettenscheid

About the department

The Department of Vascular Surgery and Angiology at the Alfried Krupp Hospital in Essen-Ruettenscheid deals with the diagnostics and treatment of patients with all types of diseases of the arteries, veins and lymphatic vessels. The medical facility offers the full range of modern therapeutic options, ranging from conservative therapy to endovascular and open surgical interventions. The priority in the department's clinical practice is given to the treatment of vascular stenoses and occlusions, abdominal aortic aneurysms, occlusive peripheral arterial disease, varicose veins, and deep vein thrombosis. In addition, the department is distinguished by its special competence in interventional procedures for the formation of dialysis access, the treatment of ulcus cruris and diabetic foot syndrome. The medical facility is certified by the German Society for Vascular Surgery (DGG) and the German Society for Angiology (DGA), which testifies to the excellent quality of medical care according to the very latest standards. Vascular surgeons and angiologists cooperate closely for the benefit of their patients in order to effectively restore their health. The department is headed by Dr. med. Thomas Nowak.

The department has excellent technical resources for high-quality diagnostics, which is essential in choosing the most effective course of therapy. The department's diagnostic rooms are equipped with advanced systems for color duplex sonography, contrast-enhanced sonography, continuous wave Doppler sonography, assessment of transcutaneous oxygen tension (TcPO2), capillary microscopy, CO2 angiography and other tests.

The tasks of angiologists include conservative treatment of diabetic foot syndrome, ulcus cruris, deep vein thrombosis, varicose veins, thrombophilia, lymphedema and circulatory disorders in the lower limbs. The specialists use highly effective latest generation medications, infusion therapy, compression therapy, decongestive therapy and other methods. If the pathology has reached an advanced stage, and the patient requires more radical therapeutic measures, the department's specialists carry out endovascular interventions, which today are the gold standard in the treatment of vascular diseases. Such operations are performed in cooperation with vascular surgeons. When performing endovascular interventions, doctors use special catheters, which allow for access to the affected area of ​​the vessel. The catheter is inserted into the vascular bed through an incision several centimeters long, under the guidance of ultrasound or CO2 angiography. The image of the operating field is transmitted to a large screen, so the doctor can clearly see the inner surface of the vessel and can perform the necessary therapeutic manipulations with maximum accuracy. In most cases, the department's doctors use endovascular techniques to implant stents and balloons in the treatment of aortic stenosis, occlusions and aneurysms.

In some cases, endovascular interventions do not allow the doctors to achieve a complete cure for vascular pathology, and therefore vascular surgeons perform hybrid operations involving a combination of endovascular and classical open techniques. The last-line therapy for vascular disease is open surgery. The advantage for the department's patients is the vast clinical experience of specialists in the field of endovascular and hybrid interventions, as well as the availability of a progressive technical base, due to which open interventions are performed only in especially complex clinical cases.
