Chronic dissection of the thoracoabdominal aorta may require surgical repair for aneurysm, malperfusion, or rupture. Endovascular repair is made difficult by a noncompliant dissection septum, visceral vessels arising from different lumens, and the common use of diseased aortic landing zones. Thus, open repair remains the gold standard in terms of favorable outcomes and durability. During thoracoabdominal aortic repair, we use a multimodal strategy to prevent spinal cord and visceral or renal artery ischemia; key modalities include cerebrospinal fluid drainage, left heart bypass with and without visceral protection, cold renal protection, and aggressive reimplantation of intercostal or lumbar arteries. Patients with chronic dissection require lifelong surveillance, as there is a significant risk for subsequent intervention on unrepaired aortic segments.

Összefoglaló. A thoracoabdominalis aorta kirekesztése a gerincvelő keringésének csökkenését okozza. Az ischemia klinikailag paraparesis, paraplegia formájában jelenik meg. Ez elsősorban nyitott műtétek során jelent aligha kiszámítható szövődményt, de a modern endovascularis technikák sem oldották meg teljes mértékben ennek biztonságos kivédését – bár arányát jelentősen mérsékelték. A javuló eredmények számos tényezőre vezethetők vissza, mint a keringés kirekesztési idejének csökkentése, a gerincvelő-funkció és metabolismus ellenőrzése. Mesterséges keringésjavító direkt és indirekt eljárások, liquor drainage, hűtés mellett a collateralis keringés javítását szolgáló prekondicionáló módszerek kerültek bevezetésre. Kísérletes munkánkban 25–30 kg testsúlyú kutyákon vizsgáltuk – más paraméterek mellett – a distalis perfusio növelésének, a liquornyomás csökkentésének, illetve ezek kombinációjának protektív hatását egyórás thoracoabdominalis aortakirekesztés során. Dolgozatunkban a kísérleti állataink neurológiai végállapotát a keringési paraméterek és szöveti perfusio és a reperfusio változásainak összefüggésein keresztül tárgyaljuk. Megállapítottuk, hogy distalis gerincvelő reperfusiós hyperaemiája szorosan összefügg a neurológiai károsodás mértékével. Summary. Clamping of the thoracoabdominal aorta reduces perfusion of the spinal cord significantly, which clinically may present as paraparesis or paraplegia – devastating and unpredictable complications of open thoracoabdominal aortic surgery. Introduction of monitoring of evoked potentials and/or biochemical markers, methods increasing distal arterial pressure, indirect procedures enhancing residual flow (like liquor drainage), drugs, and use of hypothermia contributed to achieve better outcome. Preconditioning of spinal cord circulation is also a promising method. New endovascular techniques for thoracoabdominal aortic aneurysms and dissections reduced surgical trauma significantly. Despite all these progressions spinal cord ischemic damage is still a significant risk. To address this problem we carried out an experimental work using a canine model focusing on the protective effect of distal arterial perfusion, spinal fluid drainage, and their combination in a one hour setting of thoracoabdominal aortic clamping. In this paper we publish our data of circulatory and specific perfusion parameters of the spinal cord during and after declamping in correlation of final neurologic outcome.

Abstract BackgroundAortoesophageal fistula(AEF) is a relatively rare condition that is often life-threatening.Secondary AEF is a complication ofprevious surgery,whichcan be more critical and challenging than primary AEF.The number of secondary AEF is increasing due to increase in the number of thoracic endovascular aortic repair (TEVAR). Although TEVAR has become a successful alternative surgical strategy forthoracic aortic aneurysms, secondary AEF after TEVAR might be critical than other secondary AEF because of severe adhesion between the esophagus and residual thoracic aortic wall.Methods This study analyzedsixpatients with secondaryAEFwho were treated at TokyoMedical University Hospitalbetween 2011 and 2016. These participants includedfour patients who had undergone TEVAR and two who had undergone total arch replacement.ResultsAlthough they were subsequently hospitalized for a long period, open surgical repair was completed intwo patients who had undergonetotal archreplacement.TEVAR alone was performedin two patients who had undergone TEVAR and they were discharged without major complications shortly. Combined repair of TEVARas a bridge to open surgery was plannedfor two patients who had undergone TEVAR. However, reconstruction of the aorta and esophagus could not be completed in these patients due to severe adhesions, and they died during hospitalization. ConclusionsDefinitive open repair wassuccessfully performed in patients with secondary AEF after total arch replacement. However, in the patients with secondaryAEF after TEVAR, severe adhesion between the aorta and esophagus led to difficulty in performing a successful definitive open repair.The strategy for secondary AEF should, therefore, be decided considering the etiology of secondary AEF. In secondary AEF after TEVAR, palliative treatment using TEVAR without reconstruction of aorta and esophagus should be considered.

<p><b>Background:</b> Thoracoabdominal aortic aneurysms (TAAA) present a significant clinical challenge, as they are complex and require invasive surgery. In an attempt to prevent considerably high mortality and morbidity in open repair, hybrid endovascular repair has been developed by many authors. In this study, we evaluated the early-term results obtained from this procedure.</p><p><b>Methods:</b> From November 2010 to February 2013, we performed thoracoabdominal hybrid aortic repair in 18 patients. The mean age was 68 years (12 men, 6 women). All of the patients had significant comorbidities. Follow-up computed tomography (CT) scans were performed at 1 week, 3 months, 6 months, and annually thereafter.</p><p><b>Results:</b> All patients were operated on in a staged procedure and stent graft deployment was achieved. Procedural success was achieved in all cases. All patients were discharged with complete recovery. No endoleaks weres detected in further CT examination.</p><p><b>Conclusion:</b> Our results suggests that hybrid debranching and endovascular repair of extensive thoracoabdominal aneurysms represents a suitable therapeutic option to reduce the morbidity and mortality of TAAA repair, particularly in those typically considered at high risk for standard repair.</p>

Purpose: The aim of the present study was to investigate a potential difference on the arterial stiffness among aneurysm patients and non-aneurysm controls, as well as to explore potential changes between patients treated either with endovascular or open repair. Materials and Methods: A 110 patients with an infrarenal AAA were prospectively enrolled in this study. Fifty-six patients received an EVAR, whereas 54 patients received an open surgical repair. Moreover, 103 gender and age-matched subjects without AAA served as controls. The cardio-ankle vascular index (CAVI) was applied for measurement of the arterial stiffness. Results: CAVI values were statistically higher in the AAA patients when compared with control subjects. Although at 48 hours postoperatively the CAVI values were increased in both groups when compared to baseline values, the difference in CAVI had a tendency to be higher in the open group compared to the endovascular group. At 6 months of follow up the CAVI values returned to the baseline for the patients of the open repair group. However, in the endovascular group CAVI values remained higher when compared with the baseline values. Conclusion: Patients with AAAs demonstrated a higher value of CAVI compared to healthy controls. A significant increase of arterial stiffness in both groups during the immediate postoperative period was documented. The increase in arterial stiffness remained significant at 6 months in EVAR patients. Further studies are needed to elucidate the impact of a decreased aortic compliance after stentgraft implantation on the cardiac function of patients with AAA.
