Treatment of lung cancer with embolization of bleeding vesseles in Catholic Clinic Koblenz-Montabaur

About the department

The Department of Interventional Radiology, Neuroradiology and Nuclear Medicine at the Catholic Clinic Koblenz-Montabaur provides the full range of medical services in the fields of its competence. The department has equipment of the latest generation for performing various imaging tests, including CT and MRI scans, classical X-ray scans, fluoroscopy, mammography, sonography, phlebography, myelography, and angiography. Nuclear medicine specialists are responsible for radionuclide diagnostics, with particular emphasis on performing scintigraphy and single-photon emission computed tomography (SPECT). The department also performs many image-guided interventional therapeutic procedures. The department's interventional radiologists successfully perform endovascular interventions for abdominal and thoracic aortic aneurysms, peripheral arterial occlusive disease, bile duct stenosis, abscesses, malignant tumors, etc. In the field of interventional neuroradiology, the key focus is on the endovascular treatment of carotid stenosis, stroke, chronic back pain, brain tumors, and vascular malformations in the brain. The key to achieving high treatment efficiency rates in the department is the use of state-of-the-art equipment and the professionalism of doctors. Due attention is paid to compliance with radiation protection standards and the creation of comfortable conditions for patients. The department is headed by PD Dr. med. Sascha Herber.

An essential condition for the provision of high-quality medical care in the fields of radiology, neuroradiology, and nuclear medicine is the availability of state-of-the-art equipment. The department's doctors therefore have all the necessary equipment at their disposal that allows them to perform high-precision examinations and therapeutic procedures under imaging guidance. The diagnostic rooms at the medical facility are equipped with three 1.5 Tesla magnetic resonance imaging scanners, a 64-slice computed tomography scanner with the ability to perform cardiac CT, two 128-slice computed tomography scanners, a device for head and neck digital volumetric tomography, two systems for angiography and a device for digital subtraction angiography, three digital X-ray machines, four mobile classical X-ray machines, a digital mammography system, and other devices. The department also has modern gamma cameras for scintigraphy and single-photon emission computed tomography.

The department's team of interventional radiologists specializes in sparing endovascular procedures. For this purpose, two progressive hybrid operating rooms are available here. Doctors most often carry out interventional treatment for pathological changes in the blood vessels (occlusions and stenoses), chronic back pain, malignant tumors, bile duct stenosis, abscesses, and internal bleeding. The most popular procedure is embolization, which is often performed for malignant tumors. The essence of the procedure is the image-guided placement of microspheres (emboli), coils, or special liquids (Histoacryl, Onyx, or Squid) into the blood vessel supplying the tumor using catheter-based techniques, as a result of which this blood vessel is blocked. The tumor is thus deprived of blood supply, which leads to its involution. The department also often performs percutaneous transhepatic cholangiostomy followed by stent implantation. This procedure is indicated for patients with bile duct stenosis caused by benign or malignant neoplasms. The doctor makes a puncture with a needle in the intercostal space in the liver area and delivers a drainage catheter through it to the affected bile duct under imaging guidance. This interventional procedure allows bile to be brought out through the catheter, after which a special stent is implanted in the narrowed section of the bile duct, preventing its recurrent stenosis.

Interventional neuroradiological procedures are an integral part of the department's clinical practice. Doctors in this area have rich experience in providing low-traumatic treatment for carotid artery stenosis, stroke, brain tumors, vascular malformations in the brain, chronic back pain, and other pathologies. Carotid artery stenting is one of the most requested procedures in this area. Stent implantation is performed using endovascular techniques under local anesthesia and imaging guidance. During the therapeutic procedure, the narrowing of the lumen of the carotid artery due to the formation of atherosclerotic plaques on its walls is eliminated. The goal of treatment is to restore the patency of the carotid artery, thereby normalizing the blood supply to the brain. This helps prevent the development of an ischemic stroke that may lead to serious consequences for human health or even death.

The department's neuroradiologists also offer effective interventional treatments for chronic back pain, namely periradicular therapy and facet joint infiltration. These two treatment options are very similar and involve the targeted CT-guided administration of analgesics into the pathological focus. The only difference is that in periradicular therapy, injections are made directly into the nerve roots, while in facet joint infiltration, injections are made into the facet joints. The duration of the procedures does not exceed 15 minutes. Interventional treatment for back pain is highly effective. Whenever required, it can be repeated several times. Imaging guidance using computed tomography allows for the safety of therapeutic manipulations for the patient.

The department also offers a wide range of services in the field of nuclear medicine. The specialists in this area carry out diagnostic tests and therapeutic procedures using radiopharmaceuticals. These are highly informative examinations of the brain, thyroid gland, salivary glands, lungs, kidneys, skeleton, bladder, heart (myocardial scintigraphy) at rest and under stress (physical or pharmacological stress). For early detection of tumor metastases, special labeled antibodies are used.
