Modern vascular surgery is evolving rapidly, with endovascular techniques representing the most advanced approach for the management of vascular diseases. At the 5th Vascular Surgery Clinic of Endovascular & Minimally Invasive
Techniques, we offer a comprehensive, high-level spectrum of services, aiming to provide individualized, safe, and effective treatment for each patient.
The clinic’s philosophy, grounded in extensive experience in the United States, is based on the implementation of the latest international guidelines combined with the use of cutting-edge technologies. Special emphasis is placed on endovascular procedures, which allow the treatment of even complex conditions without the need for open surgery, ensuring faster recovery.
AORTIC DISEASES
Management of aortic diseases requires high specialization and experience. The clinic offers both open surgical and endovascular approaches (EVAR, TEVAR).
- Abdominal and thoracic aortic aneurysms
- Aortic syndromes (Aortic dissection, Intramural hematoma, Penetrating aortic ulcer)
PERIPHERAL ARTERIAL DISEASE
Peripheral arterial disease is a vascular condition associated with significant cardiovascular risk. The clinic specializes in the prevention and management of complications, aiming to preserve the limb and improve daily life quality.
- Endovascular techniques (angiography, balloon angioplasty, stenting, lithotripsy, atherectomy), open surgeries (endarterectomy, bypass), and hybrid procedures for lower limb revascularization
- Management of critical limb ischemia
- Risk factor optimization and treatment of intermittent claudication
- Management of chronic ulcers
CAROTID DISEASE
Carotid disease is directly associated with stroke risk. Timely diagnosis and treatment are essential.
- Carotid endarterectomy
- Carotid stenting
VENOUS INSUFFICIENCY
Venous insufficiency is the most common vascular disorder and significantly affects quality of life. The clinic employs modern, minimally invasive treatments (Laser, Radiofrequency, Sclerotherapy).
- Varicose veins
- Telangiectasias
- Reticular veins
VASCULAR ACCESS
Vascular access is a fundamental requirement for hemodialysis.
- Creation of arteriovenous fistulas
- Placement of central venous catheters
- Restoration of vascular access dysfunctions using endovascular techniques
DIABETIC FOOT
Diabetic foot is one of the most severe complications of diabetes mellitus and is closely linked to peripheral arterial disease and microangiopathy. Timely diagnosis and specialized vascular surgical intervention are crucial to prevent severe infections and amputations.
- Lower limb revascularization when required
- Wound management and care
- Collaboration with specialized teams (internists, diabetologists, infectious disease specialists, orthopedic surgeons)
- Preventive strategies and long-term follow-up
The goal is limb preservation, restoration of functionality, and improvement of patient quality of life.
VENOUS THROMBOSIS
Venous thrombosis can lead to serious complications such as pulmonary embolism. Immediate diagnosis and appropriate intervention are vital.
- Interventional treatment using endovascular techniques (thrombectomy)
- Management of post-thrombotic syndrome
OTHER CONDITIONS
- Lymphedema
- Lipedema
- Pelvic congestion syndrome
- Visceral aneurysms
