ObjectiveReporting a case of hybrid procedure of extensive thoracoabdominal aortic aneurysm (TAAA) with type B dissection due to Marfan syndrome (MFS) using a prosthetic graft as the distal landing zone for stent-graft.MethodsRetrospectively summarize in-hospital profiles of a patient for who was diagnosed as MFS complicated with TAAA and type B dissection and admmited to Vascular Surgery Department of West China Hospital in May 2018. A GORE-TEX 18 mm×9 mm Y-shaped graft was sewn side-to-end to the bifurcation of left common iliac artery as the inflow site, and a self-made penta-limb graft was sewn side-to-end to the bifurcation of the 18 mm graft. The visceral and bilateral iliac arteries were reconstructed subsequently. Then, the release of the stent-graft was designed from distal to proximal. The distal part of the stent-graft was anchored into the main body of the 18 mm Y-shaped graft.ResultsThe patient underwent the operation successfully with a duaration of 6 h, blood loss of about 800 mL. No serious postoperative complications occurred. Computed tomography angiography at 2-year follow-up showed that the bypass grafts were patent without endoleak, stent migration, stent infolding or infections of the vessel graft and endograft.ConclusionThis modified management of the landing zone could be a proper choice for this kind of rare case as extensive aneurysm or dissection involved in patients with MFS.
The treatment of aortic dissection has already shifted to endovascular strategies. However, with the evolution of this disease and a deeper understanding of it, experts from various countries have developed a series of innovative endovascular techniques and devices in areas such as lumen reconstruction, false lumen embolization, entry sealing, and branch arteries reconstruction, targeting the long-term complication of chronic post-dissection thoracoabdominal aortic aneurysm. The past few decades have seen that Chinese vascular surgeons have gradually emerged on the world stage and contributed multiple “Chinese solutions” for post-dissection thoracoabdominal aortic aneurysm. The author in this review intends to provide an overview of these techniques and devices mentioned above.
ObjectiveTo explore the efficacy and safety of hybrid surgery in the treatment of thoracoabdominal aortic aneurysm (TAAA). MethodsTwenty patients who were diagnosed with TAAA (including chronic thoracoabdominal aortic dissection aneurysm) and underwent hybrid surgery in Vascular Surgery, West China Hospital, Sichuan University were enrolled between January 2015 and December 2022. All the patients underwent retrograde reconstruction for visceral arteries in the open surgery. Additionally, one-stage or two-stage endovascular aortic repair with covered stents was performed. The patients’ clinical baseline information was collected. Moreover, the patients received clinical follow-up and imaging examinations postoperatively, whose informationwas collected. ResultsOne patient developed paraplegia and acute renal failure 16 days postoperatively in the hospital, and subsequently died in the hospital due to septic shock. Another patient underwent exploratory laparotomy for hemostasis due to anastomotic bleeding in the hospital. The other patients did not experience serious complications perioperatively. Nineteen patients were discharged from the hospital with long-term follow-up ranging from 10 to 144 months (median time: 48 months), and all of them had a long-term survival. No patients were observed with paraplegia, myocardial infarction, stroke, or rupture of aneurysm. None of the patients received reintervention during the follow-up, except for one patient who underwent ultrasound-guided puncture and suctionin the aneurysmallumen. ConclusionHybrid surgery is an effective treatment for TAAA with favorable short- and long-term safety and efficacy.
