The suture/needle combination that would be used to oversew the renal artery for extra protection from bleeding is Silk suture with a reverse cutting needle.
The renal artery supplies blood to the kidney. If there is a blood clot in the renal artery, it can block the blood flow to the kidney. This can lead to a condition called renal artery thrombosis. Renal artery thrombosis can cause severe damage to the kidney and lead to a variety of symptoms including flank pain, decreased urine output, and high blood pressure.
