Ho-ho-ho! Gather ’round, my curious elves, for a tale of medical marvels and the wonders of flow diverter stents, those tiny cobalt-chromium sleighs that navigate the snowy peaks and valleys of our body’s vascular landscape. 🎅🛷
In the land of arteries and aneurysms, a group of wise physicians embarked on a journey to understand how these magical stents, known as the Pipeline (with its 48 wire braid) and the Evolve (boasting a 64 wire braid), could reshape the parent artery (PA) – that’s the main highway for our red-nosed blood cells, if you will. 🏥🔍
They gathered a merry band of 42 patients, each harboring tiny bulges called aneurysms, like hidden presents waiting to be unwrapped. These aneurysms, 85.4% of which were side wall types and 14.6% bifurcation types, were about to receive the gift of healing. 🎁💉
With the flick of a wrist and a sprinkle of medical expertise, the stents were deployed, and lo and behold, the arteries began to change shape! The Pipeline stent, like a team of eager reindeer, pulled the angles of the arteries by 7.04° right after deployment, and by a whopping 15.49° after one year. The Evolve, a bit more like my trusty sleigh, made a gentler curve of 5.05° initially and 10.01° over the year. 📏🎄
Now, my little helpers, you might wonder, did these changes help close off the aneurysms, much like how I seal my sack of toys? Indeed, 87.5% of these pesky bulges were completely occluded after 12 months, as if they were on the nice list all along. 🎅📜
Interestingly, the bifurcation aneurysms, those at the crossroads of arterial paths, were more likely to straighten out than their side wall counterparts, much like how a snow-laden branch might snap back after a heavy snowfall. And between our two stent heroes, the Pipeline seemed to have a stronger bending force, perhaps a bit too eager in its festive duties. 🌲❄️
In the end, while the angle changes were as clear as the star atop the Christmas tree, their role in sealing the aneurysms was like a secret Santa gift – we’re not quite sure of the connection, but it’s the thought that counts. 🌟🎅
So, with visions of stents and arteries dancing in their heads, the doctors concluded that these changes start right after the stents are deployed and continue for a year, like the slow roasting of chestnuts on an open fire. And with that, my dear elves, we close this chapter of our medical Christmas story, with hopes of healthy arteries for all, and to all a good night! 📖❤️🎅
