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.

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.
