Fig 1 Operative approach for repair of type II thoracoabdominal aneurysm with a clamp-and-sew technique supplemented with regional hypothermic adjuncts for renal and spinal cord protection. (A) The entire aneurysm sac is continuously exposed after proximal cross-clamp application. After completion of the proximal anastomosis, pulsatile arterial perfusion is established into the mesenteric circulation through in-line mesenteric shunting into either the celiac axis (as depicted) or the superior mesenteric artery. Thereafter, critical intercostals vessels are reconstructed (dotted line), and a single inclusion button anastomosis for reconstruction of celiac, superior mesenteric and right renal arteries is possible in the majority of cases. The left renal artery is reconstructed with a side-arm graft. (B) Regional spinal cord hypothermic protection is achieved via epidural cooling. A 4°C epidural saline infusion (arrow) is begun in anticipation of cross-clamping. Cerebrospinal fluid temperature and pressure is simultaneously monitored with a separate intrathecal catheter.

Fig 4 Three-dimensional reconstruction of hybrid repair of a thoracoabdominal aneurysm. The long white arrow indicates the origin of the bifurcated aorto-superior mesenteric artery and aorto-celiac bypass graft. Short arrow points to origin of aorto-left renal artery bypass.
