Paraplegia, paraparesis, and stroke occurred in 4, 1, and 2 patients, respectively; 2 cases of paraplegia occurred in patients with acute type B dissections. Thirty-day analysis revealed a statistically significant lower incidence of the following complications in the endovascular cohort versus the surgical cohort: spinal cord ischemia 3% vs 14% , respiratory failure 4% vs 20% , and renal insufficiency 1% vs 13%. The mean follow-up duration was 15. Actuarial survival was 86% at 1 year and 67% at 3 years. Fenestrated and scalloped designs are also useful for selected cases. Aortic pathologies included 31 degenerative aneurysms including two ruptures , three type A dissections and four type B dissections.
Postoperative computed tomography at discharge confirmed 100 % clinical success without any endoleaks. The actuarial survival rate was 100, 97. Three patients suffered a stroke. The new system allows for improved covered-graft apposition in tightly curved aortas and expansion control in larger diameter anatomies during the treatment of complex thoracic aortic aneurysms. The new system allows for improved covered-graft apposition in tightly curved aortas and greater expansion control in larger diameter anatomies during the treatment of complex thoracic aortic aneurysms. Early endoleak rate was 4.
The deployment sequence was analyzed. To evaluate the safety and performance of Relay stent-grafts in patients with acute or chronic aortic dissections. At the final completion angiography, device-associated complications were detected in 4. Proximal seal was achieved in all cases, with no type I endoleaks. The mean follow-up was 33. Patients with bird-beak configuration on early postoperative multidetector computed tomography require closer follow-up to screen for Type 1a endoleak. Overall actuarial midterm survival is 73% at 55 months, with an aorta-specific actuarial survival of 86% during this same time interval.
Conclusion: The scalloped stent-graft appears to be a safe and relatively simple alternative for the treatment of thoracic aortic lesions with short landing zones. Endoleaks after stent-graft repair of aortic dissections are poorly understood but seem substantially different from those seen after aneurysm repair. There were no cases of graft migration. The deployment sequence was analyzed. The 30-day and in-hospital morbidity and mortality rates, and late endoleak, graft patency, and survival were analyzed.
At the mid-term follow-up mean 22. Comparison with the modified low-porosity device at 24 months showed sac increase in 12. La maggior parte degli studi concorda nel mostrare una riduzione dei tassi di morbilità e di mortalità intraoperatorie del trattamento endovascolare rispetto al trattamento chirurgico convenzionale. Purpose: To report the perioperative results and short-term follow-up of patients treated with scalloped thoracic stent-grafts. The 30-day mortality rate was 3%. Results: None of these 51 patients suffered permanent paraplegia postoperatively, but 5 23. The distribution of the proximal landing zone was Zone 0 in one case, Zone 1 in three cases and Zone 2 in nine cases.
The association between bird-beak configuration and Type 1a endoleak remains unclear. Although endovascular treatment of aortic arch aneurysm is a recently induced procedure, only a few cases are indicated and outcomes are questionable. Endovascular correction of aortic arch pathology remains a challenge, with a variety of techniques proposed over the years to minimize complications and enhance the probability of a successful result. The mean lengths of intensive care unit stay 2. Branch vessels were 1 covered without revascularization, 2 surgically bypassed, 3 stented, or 4 fenestrated.
However, since the bird-beak configurations progressed, a conformable and flexible device for the next generation of procedures will be needed. In six cases with bird-beak configurations at the 2-year follow-up, the bird-beak length and angle had increased gradually. Anatomic complexities such as acute aortic curvature and covered side branches were associated with endoleaks, illustrating the need for dissection-specific device development. Cardiovasc Intervent Radiol 2011 34: 401. The technical success rate was 95% 97% in acute, 95% in chronic, and 93% in type B dissections. Completely retract the inner sheath with one continuous and controlled motion without.
Seventy-five percent of debranching and endovascular repair procedures were staged, with an average interval of 28 days. Results: Technical success was achieved in 28 93% patients. Major 30-day and in-hospital complications occurred in 39% of patients and included bypass graft occlusion in four, endoleak reintervention in two, and paraplegia in one. Larger patient series and long-term follow-up are required to confirm these early results. All-cause mortality at 30 days was 7. Interventions were emergent in 44. We achieved satisfactory early and short-term results with hybrid arch repair into the ascending aorta.
