Ladies and Gentlemen,
The treatment of arterial disease has changed over the last few years.
New platelet-inhibiting and lipid-lowering medications may help avoid surgerical intervention. Should drug therapy be insuffiecient, other options are traditional surgery and minimally invasive procedures.
These include balloon dilation and stent implants in the case of vascular constriction; femoral artery aneurysm repair using stent grafts; and laser therapy to repair vaicose veins.
Some crucial questions to consider are: Which procedure offers the best risk-benefit ratio for you? Is a surgical procedure necessary, or can it be avoided?
These are some of the questions we can discuss together in a quiet setting.

Personal details

Univ. Prof. Dr. Wolfgang J. Köstler studied medicine at the Medical University of Vienna, and Molecular Biology at the Weizmann Institute of Science (Israel). He also spent extended periods of study at Memorial Sloan-Kettering Cancer Center (New York) and Royal Prince Alfred Hospital (Sydney). Prof. Köstler has been a Specialist in Internal Medicine since 2004, an Associate Professor of Internal Medicine since 2005, and has had a additional specialization in Hematology and Oncology since 2007. Prof. Köstler is a Senior Physician at the Department of Oncology of the Medical University of Vienna at AKH Vienna, where he is one of two leaders of the specialist outpatient clinic for gastrointestinal stromal tumors (GIST), bone and soft tissue sarcomas. His main research areas are the identification of factors that determine the success of targeted cancer therapies and the treatment of rare tumors (publications). Prof. Köstler is also an ongoing Principal Investigator in numerous clinical studies, a partner in international research projects, and is the recipient of numerous national and international research prizes.

Prof. Köstler's main focus is on comprehensive diagnostics and therapy of tumors of the internal organs (called "carcinomas", as found in the digestive system, lungs, urinary tract etc.), breast and genitals (ovaries, uterus, prostate, etc.). He has special expertise in the treatment of solid tumors which occur mainly in young adults, such as tumors of connective and supportive tissues ('sarcoma'), and of gonads.

Prof. Köstler places special emphasis on comprehensive counseling and individually tailored oncological therapy ('personalized cancer therapy'), that specifically addresses the individual needs of his patients, and targets specific molecular and genetic tumor characteristics. He employs supplements and alternatives to conventional drug therapy methods (hormone therapy, chemotherapy), increasingly targeted therapy options such as immunotherapy with antibodies, as well as therapy with so-called "tyrosine kinase inhibitors". Some of these therapy options can be performed as outpatient procedures, while others require hospitalization. Prof. Köstler is an in-patient physician and consulting specialist for several private hospitals in Vienna, primarily at the Vienna Private Clinic and the Confraternity Josefstadt. He also provides his patients with comprehensive and interdisciplinary care during in-patient treatment, along with colleagues in other fields of expertise.

About me

A sound doctor-patient relationship on equal ground is essential to my understanding of medicine. This includes first and foremost that the patient, whether they are ill or suspected to be ill, is thoroughly counseled and is involved in all stages of diagnosis and therapy.

My job as a doctor is to conscientiously obtain all necessary findings, to interpret them correctly, and to communicate any possible consequences in a clear and comprehensible manner.

Weighing all known risks and needs, I will work with my patients to ultimately develop the best possible therapeutic approaches.

In my function as a Lung Specialist in the 1st Lung Department at Otto Wagner Hospital, my focus lies on right cardiac catheter diagnostics and infectious diseases. In addition, I have dealt intensively with interstitial and rare lung diseases (orphan diseases).

At my private medical practice I am able to provide my patients with the care they deserve, in a peaceful environment. I also offer additional diagnostics and treatment at the Vienna Private Clinic, should it be necessary.

I have many years of experience treating asthma, COPD and lung cancer.
