text: Yo, check it out, let me break it down for you
  The saphenous vein, it's used for renal artery revascularization, true
  In adults, it's a common choice, gotta mention that fact
  Vein grafts in the renal artery bed, they stay intact
  
  Compared to coronary and peripheral beds, they're more reliable
  But graft failure can occur, let me explain the why and how
  For coronary vein grafts, atherosclerotic degeneration takes its toll
  While lower extremity grafts suffer from intimal hyperplasia, that's the role
  
  Or the progression of underlying disease, it's a real threat
  But when it comes to renal vein grafts, failure is rare, you can bet
  Over time, they may dilate, but seldom do they give in
  The renal bed's got a unique flow, that's where they begin
  
  Low-resistance, high-velocity blood flow, that's the key
  It keeps the renal vein grafts going, can't you see?
  Aneurysmal degeneration is a rarity, let me state
  There's only one report of rupture, trust me, that's fate
  
  But hold on, we got another case, a late graft aneurysm ruptured
  We're shedding light on this serious complication, no need to be flustered
  Saphenous vein's still a favorable choice, keep that in mind
  For renal revascularization, it's the conduit that's defined
  
  But remember, follow-up is crucial, stay on track
  Long-term duplex ultrasound scanning, that's a fact
  Check the reconstructed artery, keep an eye on its health
  And don't forget to assess the contralateral renal artery stealth
