Purpose: To describe a dedicated technique used in fenestrated endografting (FEVAR) for juxtarenal aneurysm (JAAA) to avoid intraoperative bridging stentgraft crushing in case of adjacent origin of left renal (LRA) and superior mesenteric (SMA) artery. Case report: A 78-year-old male, at high surgical risk, underwent FEVAR for JAAA. SMA and LRA fenestrations were adjacent, at 12:30 and 2:45 o'clock evaluation, respectively. The fenestrated endograft and the bridging stentgrafts for target visceral vessels (TVVs) were deployed without complications. The completion angiography and the cone-beam CT showed patency of TVVs, except for LRA, which showed crushing of its stentgraft. SMA and LRA were re-cannulated, and the renal stentgraft was dilated with a 4 × 40 mm balloon. Finally, “Flaring-Kissing ballooning” of SMA and LRA stentgrafts was performed using two 10 × 20 mm balloon under fluoroscopy rotational guidance, to ensure the patency of both arteries. The completion angiography and the postoperative CT-angiography showed the resolution of the crushing and the patency of TVVs. The postoperative course was uneventful; the patient was discharged home after 5 days. CT-angiography at 12 months showed patency of TVVs and no endoleaks. Conclusions: The “Flaring-Kissing ballooning” of adjacent stentgrafts is a valid, safe and effective intra-procedural maneuver to preserve the patency of the TVVs.

Abstract

Purpose: To describe a dedicated technique used in fenestrated endografting (FEVAR) for juxtarenal aneurysm (JAAA) to avoid intraoperative bridging stentgraft crushing in case of adjacent origin of left renal (LRA) and superior mesenteric (SMA) artery. Case report: A 78-year-old male, at high surgical risk, underwent FEVAR for JAAA. SMA and LRA fenestrations were adjacent, at 12:30 and 2:45 o'clock evaluation, respectively. The fenestrated endograft and the bridging stentgrafts for target visceral vessels (TVVs) were deployed without complications. The completion angiography and the cone-beam CT showed patency of TVVs, except for LRA, which showed crushing of its stentgraft. SMA and LRA were re-cannulated, and the renal stentgraft was dilated with a 4 × 40 mm balloon. Finally, “Flaring-Kissing ballooning” of SMA and LRA stentgrafts was performed using two 10 × 20 mm balloon under fluoroscopy rotational guidance, to ensure the patency of both arteries. The completion angiography and the postoperative CT-angiography showed the resolution of the crushing and the patency of TVVs. The postoperative course was uneventful; the patient was discharged home after 5 days. CT-angiography at 12 months showed patency of TVVs and no endoleaks. Conclusions: The “Flaring-Kissing ballooning” of adjacent stentgrafts is a valid, safe and effective intra-procedural maneuver to preserve the patency of the TVVs.
