Treatment of cardiovascular disease with angina with cardiac catheterization and coronary bypass surgery (CABG) in University Hospital Ulm

About the department

The Department of Cardiothoracic Surgery and Vascular Surgery at the University Hospital Ulm provides effective surgical treatment for diseases of the heart, respiratory system, and blood vessels. The team of cardiac surgeons operates on patients with heart valve pathologies, coronary heart disease, heart failure, and heart rhythm disturbances. In the field of thoracic surgery, the key focus is on the surgical removal of lung tumors and lung metastases. The specialists in this area also perform surgery to repair chest wall deformities. In the field of vascular surgery, interventions for abdominal and thoracic aortic aneurysms are most often performed here. The department's vascular surgeons are also exceptionally competent in the treatment of peripheral occlusive arterial disease. A great advantage for the department's patients is that almost all surgical interventions are performed using minimally invasive techniques, so there is no need for a long postoperative recovery. The department's operating rooms are equipped with state-of-the-art technology. This allows for effective and safe treatment. The priority is always personalized medical care for patients. The department is headed by Prof. Dr. med. Andreas Liebold.

Coronary heart disease is one of the most common causes of death worldwide, and therefore the department performs coronary artery bypass grafting (CABG) almost daily. This operation is considered to be the most effective method of restoring normal blood supply to the myocardium. The department's cardiac surgeons have a perfect command of all modern CABG techniques, including the classical method with the use of a heart-lung machine, the minimally invasive method with the use of a heart-lung machine, and off-pump coronary artery bypass (OPCAB) without the use of a heart-lung machine. The optimal CABG option is selected on an individual basis after a thorough study of the patient's clinical data and potential surgical risks. Preference is always given to minimally invasive surgery if possible.

The department also regularly admits patients with heart failure. In the early stages of the disease, conservative treatment is provided, but as heart failure progresses, only a surgical procedure may be helpful. The department's specialists perform operations for resecting left ventricular aneurysms, which significantly improves the pumping function of the heart and the quality of life of the patient. Another surgical method to improve the pumping function of the heart in heart failure is reconstructive plastic surgery of the left ventricle, including the replacement of part of its wall using autologous tissue or artificial material. The department also regularly performs surgery to implant single-, dual-, and triple-chamber pacemakers and cardioverter-defibrillators. Doctors individually adjust the assistive device depending on the patient's condition, improving ventricular performance and atrial coordination.

The department's thoracic surgeons are highly skilled in performing surgery for lung cancer and lung metastases. The scope of surgery for lung cancer depends on the tumor size and the spread of the oncological process. Localized tumors are treated using tumor resection, while in advanced stages of cancer, segmental resection (the tumor is removed with part of the lung) or lobectomy (resection of a lobe of the lung) may be required. The last-line surgical treatment for lung cancer is a pneumonectomy (removal of the entire lung). To remove lung metastases, both open surgical interventions and sparing surgical procedures are performed, the most effective of which are considered to be radiofrequency and microwave ablation.

The department's team of vascular surgeons brilliantly performs operations on abdominal and thoracic aortic aneurysms. An aortic aneurysm is its pathological local expansion due to the weakening of the walls. The risk of developing pathology increases with age. The main etiologic causes include atherosclerosis, arterial hypertension, smoking, and diabetes mellitus. In some cases, aneurysm development may be caused by bacterial infections and inflammation. An aneurysm is a life-threatening condition because its rupture causes severe internal bleeding, which is potentially fatal. In most cases, aortic aneurysms do not cause any symptoms, but when they become large, they put pressure on the adjacent structures. If the aneurysm ruptures, the patient will experience sharp pain in the thorax, back, or abdomen, and the resulting internal bleeding may cause unconsciousness. Surgical treatment is indicated if the aneurysm is 5 cm or more in diameter or if the aneurysm is rapidly enlarging. The department's vascular surgeons perform classical and endovascular operations to treat aneurysms. In the first case, a special Y-prosthesis is implanted through an open approach, and in the second case, the doctor approaches the pathological focus through a femoral artery puncture, after which a stent-graft is implanted. Both interventions are performed under general anesthesia, and the duration of a hospital stay is 5-10 days.

The department's specialists also perform surgical treatment of carotid artery stenosis using classical and endovascular methods. Carotid artery stenosis occurs due to the formation of atherosclerotic plaques on the blood vessel walls. The main risk factors for pathology include smoking, elevated cholesterol levels, diabetes mellitus, and arterial hypertension. Carotid artery stenosis mostly does not cause any symptoms, so it is diagnosed accidentally during an ultrasound scan for other complaints. At the same time, carotid artery stenosis may provoke a stroke, a life-threatening condition. The department's vascular surgeons effectively eliminate carotid artery narrowing with thromboendarterectomy (classical surgery) or balloon dilatation with stent implantation (endovascular surgery). During thromboendarterectomy, the affected carotid artery is approached through an incision in the neck. The surgeon isolates the affected artery, removes the atherosclerotic plaque, and closes the incision area with a synthetic patch. The operation is performed under general anesthesia, and the duration of a hospital stay is just a few days. Balloon dilatation involves the placement of a special balloon into the blood vessel through a puncture in the femoral artery. Once positioned correctly, the balloon is inflated to eliminate the artery stenosis. The final stage of the intervention is the implantation of a stent, which keeps the blood vessel open. Endovascular intervention is performed under local anesthesia.
