RESUMO
Introduction: Endovascular treatment of an aortic stump rupture is technically feasible. Whether this is a definitive treatment or a bridge to further surgery is unknown. Report: Previously a Case of an aortic stump rupture following extra-anatomic repair of a recurrent aortoduodenal fistula (ADF), which was successfully treated endovascularly by placement of an Amplatzer® Vascular Plug was described. The patient survived this acute procedure, but four years later was admitted with fever and back pain. Imaging revealed progressive enlargement of the aortic stump. A re-exploration was performed with removal of the infected aortic stump including the Amplatzer plug. A new aortic stump was created together with resection of an adherent part of the duodenum. The patient was discharged after five months and was able to survive for two more years without any recurring vascular complications. Discussion: This Case demonstrates that after four years, endovascular treatment was not a definitive treatment for aortic stump rupture. Endovascular treatment should be followed by definitive treatment when the patient is fit for surgery, especially in cases of ADF. If the patient is unfit for surgery, conservative treatment with culture based antibiotics is a reasonable alternative. Positive obstinacy lengthened the survival of this patient with eight years of reasonably good quality life.
RESUMO
Two-stage surgical treatment of a patient with type I acute aortic dissection and lower limb malperfusion is reported in the manuscript. Frozen elephant trunk procedure was applied. A 49-year-old man was hospitalized with a diagnosis of «Debakey type I acute aortic dissection¼ in 7 hours after manifestation of the disease. At admission, paleness and numbness of both lower limbs with a violation of active movements were observed in addition to pain syndrome. Chest CT revealed false lumen thrombosis within the distal aorta followed by stenosis of aortic bifurcation up to 80% and stenosis of the right common iliac artery up to 80%. Considering critical lower limb ischemia, axillo-bifemoral bypass surgery was performed at the first stage. A day later, the patient underwent replacement of ascending aorta, aortic arch and descending thoracic aorta. E-vita Open Plus â 24 hybrid prosthesis and frozen elephant trunk procedure under hypothermia 25o C with bilateral antegrade cerebral perfusion were used. CPB time was 285 min, aortic cross-clamping time - 180 min, circulatory arrest - 135 min. Postoperative period was uneventful, ICU-stay - 5 days. The patient was discharged after 20 days. Control CT confirmed false lumen thrombosis throughout the stent-graft. Follow-up survey after 1 year revealed no complaints.

BACKGROUND: Acute type A aortic dissection complicated by malperfusion is a life - threatening emergency. The optimal management strategy for malperfusion remains controversial. CASE PRESENTATION: A 46-year-old man presented to another institution with acute type A aortic dissection with abdominal aorta occlusion. Motor and sensory grade of both lower extremities were zero. Immediate antegrade distal perfusion of both lower extremities was achieved, and total arch replacement with left axillo-bifemoral bypass was performed. At the time of discharge, motor and sensory grades of both lower extremities were 2 and 3, respectively. CONCLUSION: This case demonstrates many of the techniques in the management of acute type A aortic dissection with abdominal aorta occlusion. In this case, direct antegrade perfusion of both lower extremities and axillo-bifemoral bypass may be helpful for patients presenting with severe malperfusion of both lower extremities with acute type A aortic dissection.
