An mra confirmed that i have nutcracker syndrome in my left renal vein and right hepatic artery arising from the proximal superior mesenteric artery. could this be the cause of my uncontrolled bp &hr?

Cause is underlying : The nutcracker syndrome does not usually cause BP and heart rate variations, but I noticed u have cardiolipin antibodies which can lead to autoimmune disorders and can cause blood clots. U definitely need an ECHO=ultrasound of u'r heart and further testing by ur primary doctor and even a rheumatologist

Nutcracker Syndrome: Hypertension is very rare in Nutcracker Syndrome and it's presence is generally considered a coincident! As you probably know it generally presents with abdominal/flank pain and blood in the urine. I suggest you ask your doctor to check your Plasma Aldosterone, and plasma Renin Activity (if has not been done already) to rule out more common causes of secondary hypertension.

Yes: Limitation of blood flow to a kidney will typically raise BP. Often in such a case the BP will be very difficult to control with meds unless the blood flow is restored. A stent in the renal artery may help, but there are several studies suggesting that if meds can control the BP, then procedural risks may not be warranted. You should consult with a vascular surgeon or interventional radiologist.
