Riyadh – Mouwasat Hospital 

Mouwasat Hospital in Riyadh continues to strengthen its leadership in vascular surgery and advanced endovascular interventions, following the successful treatment of a young patient whose aortic occlusion was Treated with the Minimally Invasive CERAB technique.

Case Details 

The patient had been suffering from severe leg pain that limited his ability to walk more than 20–30 meters for the past six months, despite receiving multiple treatments at various hospitals without improvement.

The case was managed by Dr. Nikolaos Patelis, Consultant Vascular Surgeon, who diagnosed the patient with severe aortic stenosis (aortic stenosis). The patient underwent a successful minimally invasive procedure using the CERAB technique, one of the latest global innovations in treating aorto-iliac occlusive disease. 

The patient was discharged within one day, without the need for blood transfusion, and experienced 100% symptom relief, regaining his ability to walk normally. 

What Is the CERAB Technique? 

Covered Endovascular Reconstruction of the Aortic Bifurcation (CERAB) is recognized as a major advancement in the management of aorto-iliac occlusive disease, offering several benefits:

The procedure involves inserting femoral arterial sheaths, deploying specialized covered stent grafts to reconstruct the aortic bifurcation, and simultaneously inflating iliac stent grafts to ensure proper sealing and optimal blood flow. This method is particularly suitable for patients suffering from severe mobility-limiting symptoms caused by aorto-iliac arterial disease. 

Expertise of Dr. Nikolaos Patelis 

Dr. Nikolaos Patelis has an extensive record in vascular and endovascular surgery. He holds the Fellowship of the American College of Surgeons (FACS) and a master’s degree in endovascular techniques, in addition to being a member of the Hellenic Vascular Surgery Board, the European Society for Vascular Surgery, and the American College of Surgeons. 

Mouwasat… A Leader in Advanced Vascular Surgery 

This achievement reflects Mouwasat Hospital’s commitment to delivering the latest global innovations in vascular and endovascular treatments, ensuring precise and safe medical care based on the highest international standards. 

Mouwasat continues to invest in specialized expertise and advanced technologies, reinforcing its position as a leading medical destination in the Kingdom and the region and providing innovative therapeutic solutions that enhance patient outcomes and accelerate recovery.

Dammam - Mouwasat Hospital

A 69-year-old man was transferred to the Emergency Department at Mouwasat Hospital Dammam after experiencing sudden left-sided paralysis accompanied by speech difficulties—classic symptoms of an acute ischemic stroke. Upon arrival, the Code Stroke protocol was immediately activated to ensure rapid assessment and treatment according to international best practices. 

Rapid Diagnosis and Immediate Intervention 

A CT angiography of the brain was performed, revealing a critical occlusion of the right middle cerebral artery (MCA)—the main vessel supplying the right cerebral hemisphere. 

Thanks to the fast response, the patient underwent the therapeutic procedure within four hours of symptom onset, well inside the internationally recognized stroke golden treatment window (6 hours). 

Under the expertise of Dr. Agustin Ozan, Consultant of Interventional Neuroradiology, cerebral catheterization and mechanical thrombectomy were successfully performed, fully reopening the blocked MCA and its branches. 

Remarkable Recovery After Activating Code Stroke 

Due to the timely intervention and activation of the Code Stroke pathway, the patient showed significant improvement the following day:

  • Regained motor function in the left side of the body 
  • CT scan showed no intracranial bleeding 
  • Complete preservation and perfusion of the right cerebral hemisphere with no infarction 
  • Within a few days, the patient was discharged, walking independently, and in excellent health. 

What Is Code Stroke? 

Code Stroke is a rapid emergency response system designed to manage suspected stroke cases with maximum efficiency. It aims to:

  • Accelerate clinical evaluation. 
  • Transfer patients immediately for CT or MRI imaging. 
  • Enable early administration of acute stroke therapies such as intravenous thrombolysis or mechanical thrombectomy. 

Advanced Stroke Unit at Mouwasat Hospital Dammam
