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.

 Al-Khobar - Mouwasat Hospital

The medical team at Badana Center in Mouwasat Hospital Al-Khobar has successfully performed a distinguished and pioneering procedure—the first of its kind in the private healthcare sector in the Kingdom.

The surgery utilized ICG fluorescence imaging technology through the robotic surgery system to convert a previous sleeve gastrectomy into a mini gastric bypass. 

The ICG technology significantly enhanced the surgeon’s visual accuracy during the procedure, enabling the medical team to precisely assess tissue integrity and reduce potential complications such as leakage, obstruction, or other surgery-related risks associated with complex bariatric procedures. 

The medical team, led by Dr. Sultan Al Temyatt, emphasized that integrating robotic surgery with ICG technology represents a major leap in advanced bariatric surgery, offering higher levels of safety, precision, and efficiency, in addition to faster recovery and reduced postoperative risks. 

The team expressed their appreciation to all medical staff involved in this achievement, which reflects Mouwasat Hospital’s commitment to adopting the latest global technologies and delivering advanced medical care in accordance with the highest standards.

Al Khobar – Mouwasat Hospital 

Mouwasat Hospital in Al Khobar continues to strengthen its position as a leading center in pediatric urology and advanced robotic surgery, following the successful treatment of a 4-year-old girl who was suffering from recurrent flank pain and severe renal discomfort caused by a congenital ureteral obstruction. 

Accurate Diagnosis Through Advanced Imaging 

The young patient was referred to Mouwasat Hospital after undergoing a series of diagnostic studies, including:

  • Ultrasound imaging 
  • CT scan 
  • Nuclear medicine renal scans conducted in the hospital’s Nuclear Medicine Department 

The results revealed a significant narrowing of the ureter, the tube responsible for transferring urine from the kidney to the bladder. This obstruction led to hydronephrosis, reduced kidney function, and repeated pain episodes, increasing the risk of recurrent urinary infections. 

Congenital ureteral obstruction is considered one of the more complex pediatric urological conditions, and if left untreated, it may gradually progress to kidney damage or even renal failure. 

Robotic Repair of the Ureteral Obstruction 

Thanks to the expertise of Dr. Abdulrahman bin Abdulkarim Al Muhrej, Consultant in Urologic Oncology, the robotic system allowed for high-precision suturing and delicate handling of the tissues, ensuring an optimal reconstruction outcome. The procedure was completed smoothly, and the child was able to leave the hospital the next day, resuming eating and walking with only minimal pain. 

Why Robotic Surgery Is the Preferred Technique 

Robotic-assisted surgery has become the gold standard for managing complex ureteral conditions due to several advantages:

  • Exceptional precision in tissue handling 
  • Smaller incisions and reduced postoperative pain 
  • Lower blood loss 
  • Faster recovery time 
  • Higher success rates, especially in delicate pediatric cases 

Dr. Al Muhrej has performed numerous robotic repairs for ureteral obstruction in both children and adults, achieving consistently excellent clinical outcomes. 

Expanding the Role of Robotic Surgery in Urology 

Robotic systems are now widely utilized at Mouwasat Hospital for a variety of urological procedures across all age groups, including the following:

  • Partial and radical nephrectomy (kidney removal) 
  • Adrenal gland surgery 
  • Prostate surgery 
  • Bladder surgery 

This reflects Mouwasat Hospital’s commitment to incorporating advanced surgical technology and providing patients with advanced, minimally invasive treatment options. 

Important Medical Advice 

Dr. Al Muhrej stresses the importance of early evaluation when kidney dilation is detected, as determining the cause promptly is crucial to preserving kidney function. Not all cases require surgery, but timely consultation with a specialist helps guide appropriate management and prevent long-term complications.
