Endovascular Surgery in Israel

Main Endovascular Procedures:

Angiography. Radiological examination of blood vessels and lymphatic pathways.

The study allows for the identification of areas of narrowing of the vessel lumen, the site of thromboembolism, localization of an aneurysm (a pathologically dilated section of a vessel), disruption of the vessel wall integrity, bleeding, the presence of neoplasms, and the degree of pathological processes in the vascular system. The study is informative, effective, and the patient is exposed to minimal doses of radiation.

Balloon Angioplasty. Expansion of the narrowed area of the vessel by introducing a special balloon into the lumen of the blood vessel and inflating it inside the vessel. Balloon angioplasty is often accompanied by simultaneous stenting.

Stenting. Introduction of a special structure – a stent – into the narrowed area, which supports the walls of the vessel in an expanded state and prevents them from narrowing again.

Embolization. Artificial occlusion of the vessel lumen. When it is necessary to stop bleeding from internal organs, to cease blood supply to cancerous tumours, or for temporary or permanent devascularization of a specific vessel (aneurysms, varicocele), the vessel lumen is occluded with liquid sclerosing agents, special coils, or plastic particles.

Placement of a Cava Filter. Placement of a cava filter in the vena cava to prevent a thrombus from entering the pulmonary artery. The procedure is indicated for patients at risk of thromboembolism, after thrombus removal from the pulmonary artery, and others.

Drainage of the Bile Ducts. A temporary procedure performed when the bile ducts are compressed by a tumour, scar, or conglomerate. A catheter is inserted through the skin into the bile duct, allowing bile to drain.

Stenting of the Bile Ducts. The procedure is performed in cases of bile duct compression, with the goal of expanding the lumen of the duct. A stent is inserted into the duct, preventing the walls of the duct from collapsing, and bile drainage occurs naturally.

Regional Chemotherapy. A procedure for administering chemotherapy drugs directly into the organ affected by cancer. A catheter is inserted into the artery corresponding to the organ, and the drug is delivered to the neoplasm through it. This method allows for targeting the cancerous tumour while protecting the body from high doses of chemotherapy. Regional chemotherapy is better tolerated by patients and has fewer complications. Periodic angiography shows the response of the cancerous tumour to treatment.

Thrombolysis. A procedure for administering thrombolytic drugs directly into the thrombus. A catheter is placed in the center of the thrombus, through which the medication is introduced. In the presence of "young" thrombi, it is possible to completely dissolve the thrombus and thus avoid surgical intervention.
