ABSTRACT
PURPOSE: To gain insight into safety and efficacy of in situ and ex-situ fenestration techniques for total endovascular arch repair. The term ex-situ fenestration is referring to physician-modified stent-graft technique where fenestration is performed on a back table. METHODS: Electronic search was conducted according to PRISMA (Preferred Reporting Items for Systematic review and Meta-analyses) guidelines from 2000 to 2020. The main outcomes measured were 30-day mortality, stroke, aortic-related mortality, and reintervention rates. RESULTS: Fifteen studies were eligible: 7 ex-situ fenestration (189 patients) and 8 in-situ fenestration (149 patients). In ex-situ group, dissection was the main pathology treated and proximal sealing zones were Z0 or 1 in 53.5% of patients. In in-situ group, dissection and aneurysm were equally represented in around 40% of cases and proximal sealing zones were Z0 or 1 in 46.5% of patients. Cumulative 30-day all-cause mortality was similar in both groups: 3.8% (95% confidence interval [CI]: 1.7%-8.2%) and 3.8% (95% CI: 1.6%-8.9%), respectively, in ex-situ and in-situ groups and stroke rate of 2.8% (95% CI: 1.1%-7%) and 5.3% (95% CI: 2.6%-10.5%). After a 11.1 ± 2.6 months mean follow-up for ex-situ and 16.7 ± 2.3 months for in-situ group, there were 5.2 and 1.4 reinterventions per 100 patients-years, respectively, for ex-situ and in situ groups. Aortic-related mortality rates of, respectively, 3.2% (95% CI: 1.3%-7.4%) and 2.6% (95% CI: 0.9%-7.3%) were noted in ex-situ and in situ groups. CONCLUSION: The reported data show favorable short-term results of both ex-situ and in-situ fenestration techniques with low mortality and strokes rates. However, durability is still questionable given the lack of long-term data. Both options may have their place in arch repair beyond the spectrum of emergent and urgent cases, on condition that results stand the test of time. CLINICAL IMPACT: In situ and ex-situ fenestration techniques have been initially developed to overcome emergency or as a bail out techniques however giving the promessing favorable short term results indications of these techniques may be extended to elective patients ineligible to customized stent-grafts and possibly in the futur to more elective cases as an option for total endovascular arch repair.
ABSTRACT
INTRODUCTION: Traumatic Arteriovenous Fistulas (AVFs) are a rare complication of vascular injuries and pose a problem of topographic diagnosis and therapeutic management. Delayed treatment may cause cardiac and trophic complications. PRESENTATION OF CASES: We describe 4 cases of AVFs complicating stab wounds of the lower limb, associated in 2 cases with pseudoaneurysms. DISCUSSION: In two cases we performed a surgical repair, whereas in the other 2 patients we choose an endovascular treatment with wall graft stent placement. CONCLUSION: All traumatic AVFs must be treated to avoid vascular, local and general complications. Using both techniques, we had great results with no complications.
ABSTRACT
INTRODUCTION: Horseshoe Kidney (HSK) is probably the most common of all renal fusion abnormalities. However the association of Abdominal aortic aneurism (AAA) and HSK is rare, and occurred in 0,12% of patient affected by AAA. PRESENTATION OF CASE: We present a patient with the concomitant presence of AAA and HSK treated by open surgical repair with a transperitoneal approach without section of the isthmus with great outcomes after surgery. DISCUSSION: The management of AAA associated with HSK presents a special challenge during vascular surgery, given the close spatial relationship and the frequent renal arterial variations that accompanies HSK. CONCLUSION: Diagnosis and a well designed surgical strategy are required to avoid surgical post operative complications.
