Basically there isnt enough fat between your superior mesenteric and aorta to prevent the SMA from crushing your left renal vein and duodenum (beginning portion of GI tract). I have attached a nice diagram below.Your BMI is 15 which is waaay underweight. I understand how hard it is for you to gain weight without a functioning GI tract but weight gain can help decompress structures through fat pad support. There are also surgical options but many will have you try to gain weight before offering surgery. Its often a multidisciplinary team approach in treatment. GI or vascular surgery would be most appropriate to consult about options.
What do these results mean?24F, 176cm 46kg. I have hypermobile ehlers danlos & likely gastroparesis, my stomach shut down just over a year ago & I rely solely on a nasojejunal tube for nutrition, hydration and medication. I've gained 8kg from my most unwell point, but my weight has been going on a bit slowly & my blood sugars are constantly low despite feeds. I've also had issues on & off with my liver and recurrent kidney and bladder infections.I had an ultrasound followed by an MRI last year, but I didn't see the results until I called the hospital & requested the results a few months ago. It seemed to suggest nutcracker syndrome, which I know can be related to SMAS. But I've also heard MALS? I don't understand the results, and no doctor has ever even told me them, let alone explained them to me.'Ultrasound: The left renal vein was not clearly visualised crossing anterior to the aorta, and the left gonadal vein appeared dilated with reversal of flow heading downwards into the pelvis. The appearances raise the possibility of nutcracker syndrome.MRI: The aortic-SMA angle is somewhat reduced, assessed at between 17 and 30 degrees on the low quality reformatted images (normal range 38 to 65 degrees).'What does this all mean?
