Percutaneous Transcollateral Retrograde Recanalization of Isolated Dissection of the Superior Mesenteric Artery

Endovascular stent placement (ESP) for patient with spontaneous isolated dissection of the superior mesenteric artery (SIDSMA) is a widely accepted treatment option. However, failed percutaneous ESP is not uncommon and is one of the leading causes for laparotomy. We report a case of 63-year-old man with SIDSMA encountered failed antegrade recanalization via conventional transfemoral approach. We achieved recanalization in a retrograde fashion through middle colic artery using rendezvous technique and successfully placed self-expandable stents inside the dissected superior mesenteric artery. The patient recovered well after percutaneous ESP. We herein describe the transcollateral retrograde approach of percutaneous ESP for SIDSMA as an alternative option when conventional antegrade recanalization fails.
