HYGEIA Hospital

HYGEIA Hospital is a private hospital in Marousi, Athens, Greece. A group of Greek physicians founded it in 1975. The institution operates as a major medical center within a single building. It provides specialized diagnostic and treatment pathways across multiple medical fields.

Quality Standards and Milestones

HYGEIA Hospital employs 924 staff members to support patient care. The hospital holds the Joint Commission International (JCI) Gold Seal of Approval. It has maintained this certification continuously since 2010.

To protect patients, the hospital uses strict safety controls for high-risk medications. These protocols include special labeling and mandatory confirmation procedures. The European Cancer Organisation awarded the institution the INTERACT-EUROPE Gold Badge.

The hospital also holds certifications from several international medical organizations:

• American College of Surgeons (FACS)
• European Society for Medical Oncology (ESMO)
• American Society of Clinical Oncology (ASCO)
• ISO9001 quality management standard

In 2004, the hospital opened the first PET/CT department in Greece.

Clinical Specialized Departments

Oncology and Specialized Diagnostics

The hospital provides precise cancer diagnostics using modern imaging tools. Breast cancer detection uses a dedicated Automated Breast Ultrasound (ABUS) workflow. An ABUS scan takes about 15 minutes. Combining ABUS with digital mammography increases breast cancer detection in dense breasts by 37.5%.

For complex neurological cases, the hospital features a Gamma Knife Perfexion unit. This technology performs brain radiosurgery without surgical incisions. A dedicated Pediatric and Adult Ophthalmic-Oncology Center treats eye tumors in children and adults.

Cardiology and Heart Surgery

The cardiac team treats complex arrhythmias and structural heart disease. Specialists perform catheter ablation to treat atrial fibrillation (irregular heart rhythm). The standard procedure lasts about 2.5 hours. Cryoablation uses extreme cold and takes less time.

During ablation, patients receive sedation. Vascular punctures use local anesthesia. About 70% of paroxysmal atrial fibrillation patients maintain normal rhythm after one procedure. For long-standing persistent cases, the success rate reaches up to 50%. The hospital also serves as a reference center for transcatheter valve treatments.

Urology and Kidney Stone Management

The urology department focuses on prostate care, testicular tumors, and stone diseases. Prostate cancer cure rates exceed 90% at the hospital. Specialists use multiparametric MRI to guide targeted tissue biopsies. This scan takes about 25 to 30 minutes. Treatment options include robotic-assisted surgery.

Surgeons perform radical orchiectomy to treat testicular tumors. This procedure involves surgical removal of a testicle under general anesthesia through a 5–7 cm groin incision.

For upper urinary tract stones, the team offers several minimally invasive options:

• Extracorporeal shock wave lithotripsy (ESWL) – shockwaves that break stones
• Percutaneous nephrolithotomy (PCNL) – stone removal through a tiny back incision
• Ureteroscopic lithotripsy (URS) – laser stone destruction via a thin tube

Open surgery is reserved for patients with massive stone burdens or anatomical abnormalities.

Gastroenterology and Endoscopic Microsurgery

Dr. Zacharias P. Tsiamoulos directs the endoscopic microsurgery unit. The department uses IN CREM technology. This method transforms traditional endoscopy into a scarless surgical procedure. Doctors operate entirely through the gastrointestinal tract lumen.

The department partners with the HEAL Academy and the Arab Society of Gastrointestinal Endoscopy. Together, they host international courses with live cases and hands-on training.

Proctology and Laser Therapies

The proctology team specializes in treating grade II and grade III hemorrhoids. Specialists perform laser hemorrhoidoplasty, a minimally invasive alternative to traditional surgery. Dr. Stylianos G. Rossonis is a key surgeon for this procedure.

The treatment uses a flexible 2 mm laser catheter. The device delivers 980 or 1470 nm radiation directly to the hemorrhoidal nodule. This energy shrinks tissue without intense pain. Full healing takes 8 to 10 weeks.

Diagnostic and Surgical Technologies

HYGEIA Hospital invests in specialized medical hardware for diagnostic accuracy. The imaging department features the NAEOTOM Alpha Pro, a photon-counting CT scanner. This system provides high-contrast images at lower radiation doses.

For joint replacements, orthopedic surgeons use the MAKO robotic system. This platform helps plan and execute partial or total knee and hip replacements.

The hospital also has modern equipment for distinct therapeutic areas:

• Gamma Knife Perfexion for precise brain radiosurgery
• High-resolution PET/CT scanners for oncology imaging
• Multiparametric MRI systems for guided prostate biopsies
• Advanced laser catheters for proctological interventions

These systems are integrated inside multispecialty hybrid operating rooms.

Digital Services for Global Patients

The hospital belongs to the Hellenic Healthcare Group (HHG) network. International patients can manage their medical data through the my-Ygeia digital health file. This platform provides immediate online access to laboratory and imaging results. Patients can view records from all participating HHG facilities and Healthspot diagnostic centers.
