We are excited to announce the successful implementation of TJWY Medical’s NUVA flow diverter in the first overseas case in Colombia! This groundbreaking intervention was carried out by the renowned neuroradiologist Dr. Nelson Lobelo.
Case Overview:
• The patient presented with multiple unruptured giant wide-neck aneurysms. A pre-treatment panangiography revealed a right posterior communicating artery aneurysm measuring approximately 8x8mm and an additional 8x6mm saccular aneurysm in the left azygos pericallosal artery—an exceedingly rare anatomical variation.
• The left middle cerebral artery aneurysm (9x5mm) had previously been treated with a coil but required further intervention.
Surgical Highlights:
• Under general anesthesia, a puncture was performed on the right femoral artery, and a CEREBASE 8F introducer catheter was inserted.
• The left internal carotid artery (ICA) was accessed and a pathway was built using TJWY’s FREPASS microcatheter.
• A 5x20mm NUVA flow diverter, designed by TJWY, was deployed to treat the aneurysm in the posterior communicating artery with precision, achieving immediate blood flow stagnation.
• The neck of another aneurysm in the pericallosal artery was protected with a 10mm PCONUS intrasaccular device, and successfully embolized with 3 coils.
Outcome:
• The NUVA flow diverter demonstrated excellent wall apposition without complications.
• Post-surgery, branch vessels were fully preserved, and the patient’s recovery was smooth with no adverse events.
A big thank you to the entire medical team for their expertise and dedication!
