Riyadh – Mouwasat Hospital 

The Cardiac Surgery Department at Mouwasat Hospital Riyadh has successfully performed a high-risk, complex heart surgery to correct a rare congenital anomaly of the coronary arteries in a patient in his forties. This achievement reflects the hospital’s leadership in advanced cardiac care. 

Case Details 

According to Dr. Waleed Al-Ayadhi, consultant cardiac surgeon, and  Dr. Mohamed Ali, specialist in cardiac and thoracic surgery, the patient arrived at the emergency department with severe chest pain. 

 Comprehensive diagnostic tests were immediately conducted, including: 

The results revealed a rare congenital anomaly: the right coronary artery originating from the left aortic sinus instead of the right, passing through an intramural course within the aortic wall. This condition causes functional compression of the artery during exertion, which can lead to myocardial ischemia and sudden cardiac death. 

Surgical Intervention 

After thorough evaluation by a multidisciplinary team of cardiac surgeons, anesthesiologists, and intensive care specialists, and obtaining informed consent, an urgent high-risk cardiac surgery was performed to reconstruct the origin of the right coronary artery and redirect its course from the aortic wall to the normal aortic root. 

By the grace of God, the procedure was completed successfully. The patient regained consciousness immediately without complications and was discharged on the fifth day post-surgery in stable condition. 

Significance of the Achievement 

This type of coronary artery anomaly is extremely rare, occurring in only 0.2% of cases worldwide, according to recent global statistics. The surgery is considered one of the most advanced and technically demanding cardiac procedures, highlighting Mouwasat Hospital’s commitment to cutting-edge medical technology and highly specialized expertise in line with its vision to provide world-class healthcare.

Mouwasat Hospital Jubail Successfully Removes a Rare and Complex Carotid Body Tumor

Mouwasat Hospital Jubail achieved a new medical milestone as the Vascular Surgery team successfully performed a delicate surgical procedure to remove a rare and complex tumor in the carotid artery region of the neck. The tumor was classified as Shamblin III and was found in a 40-year-old patient who had been referred to the hospital after visiting several other hospitals due to the complexity of his condition.

The patient was suffering from symptoms caused by the size and extension of the tumor and its pressure on the surrounding tissues, requiring detailed medical and imaging assessments and the development of a specialized surgical plan.

A Shamblin III carotid body tumor is considered a rare and surgically complex condition due to the tumor’s close attachment to the carotid arteries and its proximity to important nerves in the neck. Its removal therefore requires a high level of precision and specialized surgical expertise to reduce the risk of bleeding or nerve injury.

Examinations showed that the tumor extended around and adhered to both carotid arteries and was associated with the hypoglossal nerve. Following careful planning, the medical team successfully removed the tumor completely while preserving the integrity of the arteries and nerves.

The procedure was performed through collaboration between the Vascular Surgery and Anesthesia teams. Careful preoperative planning and surgical precision enabled complete removal of the tumor with limited blood loss and no significant neurological complications.

By the grace of God, the patient experienced a good recovery following the operation, with intact neurological functions and no difficulties with swallowing or breathing. He remained under observation at the hospital for two nights before being discharged home in stable condition and returning to his normal life.

Such complex surgical cases require advanced expertise, precise planning, and close coordination among medical teams due to the sensitive location of the tumor and its proximity to major blood vessels and important nerves.

The success of this procedure reflects the specialized medical expertise and advanced capabilities available at Mouwasat Hospital Jubail for managing complex surgical cases, contributing to comprehensive healthcare and the best possible outcomes for patients.

These highly precise surgical procedures are part of the specialized medical services that Mouwasat Medical Services Company continues to develop and support by attracting specialized medical professionals and providing the latest technologies and equipment to enhance the quality of healthcare provided to patients.

First in Saudi Arabia’s Private Sector: Successful Total Gastrectomy with Lymph Node Removal at Mouwasat Hospital Khobar

For the first time in the private healthcare sector in Saudi Arabia, Mouwasat Hospital Khobar successfully performed a total gastrectomy with lymph node removal using robotic surgery. The procedure treated a tumor in the upper part of the stomach and represents a medical achievement considered the first of its kind in the Kingdom’s private sector.

The operation was performed under the supervision of Dr. Sami Al-Asiri, Consultant in Robotic Surgery and Gastrointestinal Oncology, as part of an integrated treatment plan for a patient in his sixties. The plan began with the necessary examinations and assessments, followed by chemotherapy and radiation therapy. After completing the treatment plan, the patient underwent total gastrectomy with lymph node removal and reconstruction connecting the esophagus to the small intestine.

The surgical team performed the procedure using robotic surgery without the need to open the abdomen or chest, through small incisions. This helped reduce pain and accelerate recovery while providing a high level of precision during complete removal of the tumor and lymph nodes.

By the grace of God, the operation was successful, and the medical team was able to completely remove the tumor along with the lymph nodes. The patient experienced a rapid recovery and passed through the postoperative period in stable condition.

Total gastrectomy procedures are complex and highly precise, particularly when associated with tumors and the need for lymph node removal. However, the use of robotic surgery enabled the medical team to manage the case with high precision while benefiting from the advantages of minimally invasive surgery.

This achievement reflects, by the grace of God first, the specialized medical expertise, modern technologies, and integration across the different stages of cancer treatment available at Mouwasat Hospital Khobar, enabling the hospital to provide advanced surgical solutions for complex cases.
