Riyadh – Mouwasat Hospital 

In a remarkable medical achievement, the Cardiac and Thoracic Surgery Department at Mouwasat Hospital Riyadh successfully performed a highly complex and high-risk surgery to remove a massive anterior mediastinal tumor measuring 18 cm × 15 cm and weighing approximately 3 kilograms, which was intertwined with the heart and major arteries. The procedure was carried out on a patient in his forties. 

Case Details 

Dr. Waleed Al-Ayadhi – Consultant Cardiac Surgeon, and Dr. Mohamed Ali – Specialist in Cardiac and Thoracic Surgery, explained that the patient had been suffering from severe chest pain and shortness of breath due to a large mediastinal mass compressing vital structures, including the heart, superior vena cava, aorta, major arteries, main pulmonary artery, trachea, and the left lung. 

Complex Surgical Intervention 

Following detailed diagnostic imaging, including CT scans, the surgical team decided to proceed with an open-chest procedure to completely remove the tumor. The surgery lasted several hours and required exceptional precision due to the tumor’s adhesion to critical surrounding structures. 

Post-Operative Outcome 

Thanks to advanced surgical expertise and meticulous planning, the operation was completed successfully without complications. The patient regained consciousness normally and was discharged on the fifth day post-surgery in stable condition. 

Commitment to Excellence in Healthcare 

This achievement highlights the advanced capabilities of the Cardiac Surgery Department at Mouwasat Hospital Riyadh and reflects Mouwasat Medical Services Company’s vision to attract highly skilled specialists and provide cutting-edge medical technologies to deliver world-class healthcare in line with international standards.

A new historical medical milestone has been achieved at Mouwasat Hospital in Jubail by diagnosing and successfully treating the first confirmed case of pulmonary paragonimiasis in Saudi Arabia.

Further examinations uncovered a rare complication, a scrotal abscess, which was surgically removed in a successful procedure.

  • Dr. Mohamed El-Deeb – Consultant in Critical Care 
  • Dr. Mahmoud Hassan – Consultant Urologist

The patient came with chronic bleeding and low hemoglobin levels. After comprehensive diagnostic tests, including imaging and endoscopy, a tumor was detected in the right colon near the liver, requiring immediate surgical intervention.
