Treatment focus

  • Arterial blood circulation disorders of the legs: claudication (peripheral arterial disease, PAD), smoker’s leg, gangrene, aneurysm (wall bulge of the arteries)
  • Venous blood circulation disorders of the legs: varicose veins, venous thrombosis, venous occlusions, chronic vascular insufficiency, leg ulcers ( "ulcerated leg")
  • Circulatory disorders in the abdomen: abdominal aortic aneurysm, aneurysm of visceral arteries (abdominal arteries) and renal arteries, stenosis (narrowing) and occlusions of the visceral arteries
  • Circulatory disorders of the blood vessels of the arms and carotid arteries: circulatory disorders of the hand and the brain, such as stroke, TIA, thoracic outlet syndrome (TOS, shoulder girdle compression syndrome), other entrapment syndromes (arterial compression syndromes of neck and shoulder such as impingement syndrome)
  • Vascular tumours
  • Vascular malformations

Medical range

Range of Diagnostic Services

  • Application of clinical tests for vascular examination
  • Duplex sonography (ultrasound examination of the blood vessels, judgement of vessel course and vascular texture)
  • Doppler ultrasonography (evaluation of the flow behaviour in the vascular system)
  • Angiography (radiological angiography)
  • Computed tomography (CT), magnetic resonance imaging (MRI, magnetic resonance imaging)


Range of Therapeutic Services

  • Conservative and drug treatment approaches (e.g. walking exercise with intermittent claudication (peripheral arterial disease, PAD), compression treatment to prevent thrombosis, blood thinning, decongestive treatment)
  • Bypass surgery (surgical creation of "bypass paths" with plastic prosthesis, with biografts, with patient's own vein), stenting
  • Thrombectomy (removal of thrombi (blood clots))
  • Endarterectomy ( "vessel cleansing" of deposits, plaques, "removal grafting", including carotid endarterectomy, in case of risk of stroke from carotid artery)
  • Varicose vein surgery, stripping, crotchet technique
  • Aneurysm surgery (open surgery or endovascular (minimally invasive))
  • Treatment of chronic ulcers (e.g. "ulcerated leg") or large, soft tissue defects provoked by vascular causes through different flap techniques (Thiersch graft, advanced flap, pedicle flap)
  • Pulmonary embolism prophylaxis


Prof Dr Jon Largiadèr is a long-standing specialist in the field of vascular surgery and is working in his private practice Vascular Surgery Zurich since 1997. He is also an attending physician at the Klinik im Park, Klinik Hirslanden, Klinik St. Anna, in the private clinic Bethanien and See Spital Kilchberg Zurich. This gives his patients the opportunity to undergo surgery there directly from the vascular surgeon whom they trust.

Arterial and venous circulatory disorders are treated both conservatively and surgically by Prof. Largiadèr. The core competencies of Prof. Largiadèr include the treatment of arterial blood circulation disorders of all kinds, as well as surgical treatment of varicose veins and thrombosis of the lower and upper extremities.

Varicose veins (varices, varicose veins, spider veins) are a widespread problem that are increasingly affecting women. The veins begin to widen up, especially the superficial leg veins. The disease is primarily an aesthetic problem for most of the people but in its advanced stages, it can cause an unpleasant feeling of tightness and pain besides leading to oedema (swelling).

Thrombosis (closure by blood clots) of the veins frequently occurs with bed rest, after major surgeries or after immobilization of extremities (e.g. through plaster cast). To prevent the the clots from reaching out to the lungs (pulmonary embolism), the patients receive antiplatelet medications and compression stockings, and in some severe cases, vascular surgery in form of thrombectomy may also be necessary.

Circulatory disorders can either be acute or chronic. In such disorders, the blood flow within the blood vessels is restricted. The extremities (arms, legs), as well as brain and heart are the more commonly affected regions. Circulatory disorders can lead to a heart attack. The brain can be irreversibly damaged for life by a stroke (acute interruption of blood flow). With age, blood lipids, blood clots and connective tissue get deposited inside the blood vessels. This leads to an increasing constriction of blood vessels (arteriosclerosis). In addition, the deposits can loosen and lead to vascular occlusions in the brain for example (stroke). The procedure of carotid endarterectomy (removal grafting of the carotid artery) in which the carotid artery is surgically exposed and freed from the intravascular deposits helps reduce the risk of stroke dramatically.

Severe arterial circulatory problems in the legs may be seen in the form of peripheral arterial disease (PAD, claudication) for example. There is a hypoperfusion of the extremities leading to pain during exercise. In advanced stages, the pain might even occur at rest and trophic disorders such as necrosis, gangrene or ulceration (leg ulcers, ulcers on the lower leg by chronic hypoperfusion) may be seen. As smoking is an important risk for peripheral arterial disease, this disease is colloquially known as smoker's leg. Cold, bluish hands are often seen in circulatory disorders of the arms and hands. This may be a symptom of Raynaud's syndrome or other autoimmune diseases.

An aneurysm is a localised bulge in the wall of a blood vessel. If this ruptures, it may cause major bleeding, especially in the abdomen (abdominal aortic aneurysm, aneurysm of renal or visceral arteries) or in the brain. In order to prevent this complication, various vascular surgical techniques are employed.

The umbrella term Angioma deals with malformations of the blood vessels. This may be a developmental issue or tumorous. Haemangioma is a tumorous vascular malformation. It is among the most common tumours of childhood. Haemangiomas are usually congenital and usually do not degenerate. If complications such as bleeding, blood clots or ulcerations (sores) are seen or the tumour begins to grow very rapidly, treatment may be necessary. This can be in form of surgical removal, laser therapy or topical application of various drugs (cortisone, cold, etc.) for example.
