Five Year Post-Endovascular Aneurysm Repair Aneurysm Sac Evolution in the GREAT Registry: an Insight in Diabetics Using Propensity Matched Controls.

OBJECTIVE: To assess differences in the five year abdominal aortic aneurysm (AAA) sac regression rate after endovascular aneurysm repair (EVAR) in patients with and without diabetes mellitus (DM). METHODS: An international prospective registry (Europe, USA, Brazil, Australia, and New Zealand) of patients treated with the GORE EXCLUDER endograft. All scheduled EVARs for infrarenal AAA between 2014 and 2016 with complete five year imaging follow up were included. Emergency procedures, ancillary proximal procedures, and inflammatory and infectious aetiologies were excluded. Descriptive and inferential statistics, and Cox proportional hazards survival models were used. A control group of patients without DM with similar age and comorbidities was selected using propensity scores, matched in a 1:2 scheme. RESULTS: A total of 2 888 patients (86.1% male; mean age 73.5 ± 8 years) was included, of whom 545 (18.9%) had DM. Patients with DM had higher rates of hypertension (89.2% vs. 78.4%), dyslipidaemia (76.0% vs. 60.7%), coronary artery disease (52.3% vs. 37.9%), and chronic renal impairment (20.9% vs. 14.0%) (all p < .001). The mean pre-procedural AAA diameter was 58.1 ± 10 mm. Five years post-EVAR, the type 1A endoleak rate was 1.1% (0.6% DM vs. 1.2% non-DM), the endograft related re-intervention rate was 7.3% (6.2% vs. 7.6%), the major adverse cardiovascular event (MACE) rate was 1.4% (1.1% vs. 1.5%), and aortic related mortality rate was 1.0% (0.6% vs. 1.2%), without statistically significant differences between groups. The overall five year mortality rate was higher in diabetics (36.3% vs. 30.5%; hazard ratio [HR] 1.30, 95% confidence interval [CI] 1.07 - 1.58; p = .001). No statistically significant differences were found in sac regression rate (≥ 5 mm) between diabetics and non-diabetics 70.0% vs. 73.1%; HR 0.88, 95% CI 0.75-1.04; p = .131. These differences remained statistically non-significant after excluding patients performed out of instructions for use (p = .61) and patients with types 1, 2 or 3 endoleaks (p = .39). CONCLUSION: The paradoxical relationship between DM and AAA does not appear to result in differences in post-EVAR sac regression rates. However, even when controlling for other comorbidities, patients with DM undergoing EVAR may have a higher five year mortality rate.

Self-Made Bovine Pericardial Tube Grafts for the Treatment of Abdominal Aortic Infections.

BACKGROUND: Aortic infections are uncommon but life-threatening diseases. The material of choice for aortic reconstruction is still a matter of debate. The aim of this study is to examine the short- and mid-term outcomes in the treatment of abdominal aortic infections using self-made bovine pericardium tube grafts. METHODS: This retrospective, single-center study collected all patients who underwent in situ abdominal aortic reconstruction using self-made bovine pericardial tube grafts between February 2020 and December 2021 in a tertiary care center. Patient comorbidities, symptoms, radiological, bacteriological, and perioperative findings, as well as postoperative outcomes, were analyzed. RESULTS: Bovine pericardial aortic tube grafts were used in 11 patients (10 males, median age 68.7 years). Two patients presented with a native aortic infection, and 9 had graft infections (4 bypass grafts, 4 endografts, and a plurioperated patient who had undergone both endovascular and open procedures). There were 2 emergent surgeries due to infectious aneurysm ruptures. All patients were symptomatic, and the most frequent clinical finding was lumbar or abdominal pain (36%), followed by wound infection (27%), and fever (18%). Seven bifurcated and 4 straight pericardial tube grafts were needed. Purulent drainage was obtained around the previous graft or in the aneurysmal sac in 7 cases; intraoperative cultures were positive in 6 cases (gram + bacteria). Two patients died in the immediate postoperative period (perioperative mortality 18%; urgent procedures 50%; scheduled procedures 11%). One patient had a major complication due to bilateral severe acute respiratory syndrome coronavirus 2 pneumonia. There was 1 single reintervention to control hemostasis due to bleeding nongraft-related. The median follow-up was 14.1 months (3-24 months). CONCLUSIONS: Our preliminary experience in the treatment of abdominal aortic infections by in situ reconstruction with self-made bovine pericardial tube grafts shows promising results. These should be confirmed in the long term.

Outcomes of Self-Expanding Covered Stents for the Treatment of External ILIAC Artery Obstructive Disease.

PURPOSE: To describe the early results and mid-term patency rates of external iliac artery (EIA) stenting using self-expanding covered stents. METHODS: We conducted a multicenter retrospective study (2015-2021), including patients receiving primary endovascular treatment of external iliac artery occlusive disease with self-expanding covered stents. All patients were treated with the Viabahn (W.L Gore & Associates, Inc., Flagstaff, AZ-USA) stent. Patency and limb salvage rates were estimated with Kaplan-Meier curves. RESULTS: Ninety-three patients (mean age, 69 ± 9 years; 81% males) were treated for disabling claudication in 44%, rest pain in 28%, and tissue loss in 28%. TASC C/D lesions were present in 72% and iliac complete occlusion in 30%. Mean lesion length was 6.9 ± 2.4 cm; 30% had moderate/severe EIA calcifications; and the mean iliac tortuosity index was 1.17 ± 0.13. Technical success was 100%. There was one perioperative death (1.4%) and procedural complication rate was 6.5%. At 42 months (mean, 25 months), primary patency was 89.8% (95%CI 83-98); the presence of EIA tortuosity (tortuosity index > 1.25, 87.7 ± 11% vs 89.9 ± 8%; P = .6) or severe calcifications (87.6 ± 9% vs 96.0 ± 8%; P = .400) had no significant impact. After univariate analysis, the use of a stent with diameter < 8 mm (HR 8.5, 95%CI 3.24-14.22; P < .001) was negatively associated with primary patency. CONCLUSIONS: The use of self-expanding covered stents provided excellent early and mid-term results in the treatment of obstructive disease of the EIA, also in cases of high EIA tortuosity and high grade of calcifications. The use of a < 8 mm-diameter stent was associated with a reduced primary patency.

An early single-center experience with the Relay double inner-branch arch endograft.

Background: Open surgery remains the gold standard technique for the treatment of aortic arch pathologies, although endovascular techniques offer a new opportunity for patients deemed unfit for open repair. This paper assesses the early outcomes of patients treated with a double inner-branched arch endograft in a single, tertiary-care institution. Methods: All consecutive cases of elective endovascular arch repair from 2016 to 2022 were included in a prospective database. All procedures were performed using the custom-made Relay® (Terumo Aortic-Bolton Medical Inc., Sunrise, FL, USA) double inner-branched endograft; an extra-anatomical bypass was associated in all cases to preserve the patency of supra-aortic trunks. Comorbidities, periprocedural data, immediate results and follow-up complications were analyzed. Results: Twelve patients were treated during the study period [mean age 74±7 years, 100% male, 58% American Society of Anesthesiologists (ASA) risk ≥3]. Treated conditions included aneurysms (n=9), one pseudoaneurysm, one aortic ulcer and a type IA endoleak. The technical success rate was 100%. Early complications included respiratory insufficiency (n=3; 25%), stroke (n=1; 8.3%), acute coronary syndrome needing coronary stenting (n=1; 8.3%), and one perioperative death (n=1; 8.3%) secondary to an intracranial bleeding after coronary stenting. One patient required early reintervention due to retroperitoneal iliac access bleeding (n=1; 8.3%). During a median follow-up of 15.5 (range, 0-44) months, four patients suffered neurological events (two of them of cardioembolic origin), one reintervention was needed (subclavian anastomosis pseudoaneurysm), and a type IB endoleak was diagnosed. Overall mortality was of 17% (n=2), with an 83% overall survival at 2 years. The aortic-related death-free survival was 100%. Conclusions: Endovascular treatment of aortic arch pathology is feasible and shows promising early mortality and stroke rates in high-risk candidates. The main short and midterm goal should be minimizing neurological complications. A longer follow-up is mandatory to determine the effectiveness of the technique and to detect device related complications.

Midterm results of endovascular versus open surgical repair for infrarenal abdominal aortic aneurysms in low surgical risk patients.

OBJECTIVE: The objective of this study was to analyze midterm outcomes of endovascular repair (EVAR) versus open repair (OR) for treatment of infrarenal abdominal aortic aneurysms (AAAs) in low surgical risk patients. METHODS: Elective patients with AAAs undergoing treatment from 2003 to 2017 in a single, tertiary-care institution were evaluated. All patients with a low preoperative risk of complications and perioperative mortality (Medicare Aneurysm Scoring System <3) were included, and rates of perioperative and long-term mortality, adverse events, and reintervention were evaluated for EVAR and OR. A propensity score-matched cohort, leveling age, risk factors, and comorbidities was additionally performed. RESULTS: A total of 227 patients were included (EVAR 59.9% and OR 40.1%) and followed for a mean of 80 ± 48 months. Patients undergoing EVAR were older (66.6 ± 5 vs. 64.1 ± 6 years; P <.001), had a higher body mass index (29.6 ± 4 vs 28.1 ± 3 kg/m2; P = .005), a higher prevalence of chronic obstructive pulmonary disease (27.3% vs 9.9%; P = .001), and lower prevalence of dyslipidaemia (46.3% vs 65.9%; P = .004). Patients undergoing OR had a higher rate of major adverse events (19.7% vs 2.6%; P = .001) and 30-day reinterventions (8.8% vs. 1.5%; P = .016), with 30-day mortality being 0% in both groups. The propensity-score matched cohort included 76 matched pairs (1:1), with differences in hospital stay and major complications remaining significant, without affecting mortality. At 5-year follow-up, there were no significant differences in the reintervention rate (EVAR 18.5% vs OR 17.6%; P = .67) or survival (EVAR 85% vs OR 91%; P = .195). CONCLUSIONS: In low surgical risk patients with AAAs, EVAR may offer comparable midterm results to OR, with a lower rate of major adverse events and a shorter in-hospital stay. With the current OR-first paradigm in low-risk patients, several factors should be taken into account for decision-making (anatomic suitability, risk of sexual dysfunction, risk of type 2 endoleaks, and need for follow-up).

Endovascular Treatment of a Traumatic Axillary Artery Rupture Using the Dual Bull's-Eye Technique.

BACKGROUND: Our purpose is to report a case of an axillary artery rupture treated by endovascular means using the dual bull's-eye technique. An 83-year-old woman with multiple comorbidities was diagnosed with axillary artery rupture after the reduction of a shoulder dislocation. METHODS: An endovascular repair attempt was made, but, despite the use of a double approach (antegrade and retrograde), reconnecting both ends of the severed artery was deemed not possible. 5-mm Amplatz GooseNeck snares were advanced from each access and superposed in a perpendicular plane. A percutaneous infraclavicular puncture with a lumbar needle was made through both snares, and a V14 guidewire was subsequently introduced. The guidewire was recovered through femoral and brachial accesses, and a 7 × 100 mm covered self-expandable stent was deployed. RESULTS: The final angiographic control did not show further hemorrhage, and the patient recovered radial pulse. Follow-up showed complete patency and no complications at 9 months after the procedure. CONCLUSIONS: The dual bull's-eye technique can be used as a resource tool in cases of arterial rupture, when the arterial continuity cannot be re-established by conventional approaches.

Predictive Factors of Aneurysm Sac Growth in Patients with a Type II Endoleak in the First Post-EVAR Control.

BACKGROUND: The objective of this study was to identify predictive factors associated with aneurysm sac growth over time in patients diagnosed with a type II endoleak (TII-EL) in the first postoperative control after endovascular aneurysm repair (EVAR). METHODS: A retrospective analysis of all patients undergoing an elective EVAR procedure from January 2003 to December 2011 (9 years) in a single center was performed. Patients with a TII-EL detected in the first post-EVAR imaging control and with over twelve months of follow-up were included. The primary end point was aneurysm sac growth > 5 mm from the first month computed tomography angiography (CTA) to the last available CTA. Demographic variables, cardiovascular risk factors, comorbidities, aneurysm-related data, and procedural information were collected. Three-dimensional volume rendering with the Mimics ® software (Materialise NV, Leuven, Belgium) was used to measure the endoleak nidus. Descriptive, univariate, and multivariate analyses (Cox proportional hazards model) were performed. RESULTS: In this period, 220 EVAR procedures were performed. 63 TII-ELs (28.7%) were detected in the first CTA control (90.5% male, mean age: 75.7 ± 8 years). After a median follow-up of 54 months (interquartile range [IQR], 56.5), aneurysm sac growth > 5 mm was detected in 19 patients (30.1%). Age (P = 0.02) and dyslipidemia (P = 0.03) were associated with sac growth > 5 mm, whereas the presence of chronic obstructive pulmonary disease (COPD) behaved as a protective factor (P = 0.02). The craniocaudal length of the endoleak nidus (P < 0.01) and the nidus volume (P < 0.001) were the only aneurysm-related variables associated with sac growth. Age (HR: 14.1, 95% CI: 2.1-92.3, P = 0.006) and the presence of COPD (HR: 9.6, 95% CI: 1.4-63.7, P = 0.019) were the only independent predictors in the multivariate analysis. CONCLUSIONS: Reliable predictors of long-term aneurysmal sac growth are lacking, although some variables such as age or nidus volume appear to be associated. Strict surveillance remains mandatory.

Midterm Results of Endovascular Treatment for Complete Iliac Axis Occlusions Using Covered Stents.

BACKGROUND: Endovascular treatment of complex aortoiliac disease is seeing a growing popularity despite the Trans-Atlantic Inter-Society Consensus (TASC) II recommendations for open surgery in this cases. However, the available evidence does not focus particularly on patients with complete unilateral iliac axis obstruction (CIAO) (TASC II D4 group). This study reports mid-term results of endovascular therapy with covered stents for CIAO. METHODS: This is single-center retrospective review of patients with CIAO endovascular treatment from January 2015 to December 2017 (3 years). Two types of covered stents were used, alone or combined: the Viabahn self-expandable stent (W. L. Gore, Flagstaff, AZ) and the Advanta V12 balloon-expandable stent (Atrium-Maquet, Hudson, NH). Thirty-day outcomes, long-term patency (assessed with Kaplan-Meier estimates), in-hospital stay, and limb salvage were analyzed. RESULTS: Thirty-nine patients with CIAO were treated in the period (87.2% male, mean age 64.3 ± 9 years). A majority presented with critical limb ischemia (56.4%, n = 22). Recanalization could be accomplished from an ipsilateral or contralateral femoral access in 82.1% of patients (1 case needed the use of a re-entry device), and from a left brachial access in 17.9%. Technical success was 100%. About 66.7% of cases received an aortic kissing stent technique. Common femoral artery/profundoplasty with prosthetic or bovine patch was associated with 74.3% of cases. Thirty-day mortality was 2.6% (1/39). Primary, assisted, and secondary patency rates at 24 months were all 96.8%. Mean in-hospital stay was 5 days; no limb loss was registered during follow-up. CONCLUSIONS: Endovascular treatment of complete iliac axis occlusions can offer comparable midterm patency rates to open surgery aortoiliac femoral bypass, when an adequate combination of balloon and self-expandable covered stents is used and an appropriate outflow through the common femoral artery is warranted.

Immunological Aspects Involved in the Degeneration of Cryopreserved Arterial Allografts.

Introduction: Cryopreserved arterial allografts have remained an option in patients requiring distal revascularization or associated with vascular infection, in the absence of a valid autogenous saphenous vein. The objective of this study is to describe the different clinical, anatomopathological, and immunological findings related to vascular transplant rejection. Methods: In a prospective trial, 35 patients who underwent cryopreserved allogeneic arterial bypass were studied, including demographics and conduit patency. Anti-HLA antibody production was stablished prior to the surgery, 7 days, 1, 3 months, and every 3 months since. Clinical and ultrasound evaluation was added after the first month. Donor HLA-typing was retrieved whenever available, allowing for the characterization and quantification of donor specific antibodies. Cytotoxic crossmatch test was also performed. A second group of patients with allograft degenerations registered during the follow up period was studied. In this group, exclusively for aneurysm description and histopathological analysis, they were included those degenerated vascular transplants from the original series, but also those implanted prior to the beginning of the study and degraded during follow up. Results: All patients studied displayed an increase in anti-HLA antibodies one month after the intervention, regarding bypass patency. In total, 14 patients fulfilled requirements for the study of donor specific antibodies, equally showing IgG production detectable one month after surgery. The presence of complement-fixing antibodies was also confirmed. Antibody levels were not related to graft degeneration. No specific immune markers able to predict aneurysmal development and evolution were found. From the original group, 3 patients suffered aneurysmal degeneration during follow up, together with 9 bypasses previously implanted. Average time until the first degeneration was 33 ± 19.7 months, with 30.6 ± 17.7 and 54.5 ± 2.5 months for a second and third degeneration, when occurring. Therefore, subsequent vascular transplants frequently augmented the time for new degenerations, despite increasing sensibilization. Samples from eight degenerated allografts were available for analysis, unexpectedly showing inflammatory infiltrate in only four cases and immune complex deposition in 7. Conclusions: Immune response against vascular transplants was confirmed in all cases, but chronic rejection did not necessarily provoke bypass degradation or reduced the time for new aneurysms to develop in subsequent allografts.

[Blue toe syndrome as a clinical finding of pheochromocytoma]. / Síndrome del dedo azul como manifestación de feocromocitoma.

Pheochromocytomas are tumors that arise from chromaffin cells of the sympathetic nervous system and act by synthesizing and releasing catecholamines. They usually occur between the fourth and fifth decade of life and have a very wide clinical presentation. They occur only in 0.1-0.2% of the hypertensive population and represent a treatable and curable cause of arterial hypertension, as well as other symptoms derived from the uncontrolled secretion of catecholamines. Peripheral arterial ischemia secondary to massive amines release by a pheochromocytoma is a very uncommon condition. Here we report a case of pheochromocytoma manifested as blue finger syndrome in a patient with palpable distal pulses and history of poor blood pressure control despite treatment with two drugs.

Síndrome del dedo azul como manifestación de feocromocitoma / Blue toe syndrome as a clinical finding of pheochromocytoma

Los feocromocitomas son tumores que proceden de las células cromafines del sistema nervioso simpático y actúan sintetizando y liberando catecolaminas. Suelen presentarse entre la cuarta y quinta década de la vida y tienen presentaciones clínicas muy diversas. Ocurren solamente en 0.1-0.2% de la población hipertensa, constituyen una causa tratable y curable de hipertensión arterial, así como de otras manifestaciones derivadas de la liberación incontrolada de catecolaminas. La isquemia arterial periférica secundaria a la liberación masiva de aminas por un feocromocitoma es muy infrecuente. Aquí se presenta un caso clínico de feocromocitoma manifestado como síndrome del dedo azul en un paciente con pulsos distales conservados y el antecedente de mal control tensional a pesar de tratamiento con dos fármacos.

The Use Of The Gore® Hybrid Vascular Graft For Treatment Of Complex Iliofemoral Revascularization Procedures.

PURPOSE: To describe the uses and advantages of hybrid vascular grafts (HVGs) for complex iliofemoral revascularization procedures. CASE REPORT: We report 3 cases of iliofemoral occlusions repaired with the Gore HVG, used as an alternative technique to standardized common femoral artery (CFA) endarterectomy associated with iliac stenting or open repair. The indication in each of the 3 cases was different: In the first case, there was an absent CFA secondary to a mycotic pseudoaneurysm, in the second case, an iatrogenic lesion of the posterior wall of the CFA during the intervention was performed, and in the third case, the indication was because of thrombosis of a previous iliofemoral revascularization procedure. CONCLUSION: Although we only present 3 cases, the Gore HVG can be useful for complex iliofemoral revascularizations, serving as an alternative to standardized CFA endarterectomy plus iliac stenting in cases where there is a damaged or absent CFA, especially in high-surgical risk patients.

Características de los pacientes con enfermedad crónica avanzada incluidos en un programa de cuidados paliativos domiciliario / Characteristics of patients with advanced chronic disease included in a domiciliary palliative care program

OBJETIVO: Conocer las características sociodemográficas y clínicas, y los aspectos relativos a información de los pacientes no oncológicos (PNO) en situación de enfermedad avanzada-terminal incluidos en un programa de cuidados paliativos domiciliario. Identificar las variables que pudieran estar relacionadas con el fallecimiento en el domicilio. Material y MÉTODO: Estudio descriptivo retrospectivo mediante revisión de historias clínicas de los PNO atendidos por un Equipo de Soporte de Atención Paliativa Domiciliaria durante el periodo comprendido entre noviembre de 2009 y marzo de 2013. Se analizaron datos sociodemográficos y clínicos del paciente y del cuidador principal, los conocimientos sobre el diagnóstico y el pronóstico del paciente y la familia, las preferencias para el cuidado y el fallecimiento de ambos y el lugar del fallecimiento. Para el análisis de los datos se utilizó el paquete informático SPSS(R) v.21. RESULTADOS: Se revisaron 371 historias, de las cuales 249 cumplieron CRITERIOS DE INCLUSIÓN: Los PNO representaron el 36,19% de la actividad, con una media de edad de 81,4 años. La enfermedad más frecuente fue la demencia (22,1%). El 67,5% de los pacientes procedían de Atención Primaria y del medio residencial. El motivo de derivación fue en un 85,5% para el control de síntomas, siendo los más frecuentes astenia, disnea y dolor. Los pacientes presentaron una comorbilidad alta, frecuentes síndromes geriátricos, algún grado de deterioro cognitivo en un 65% y deterioro funcional importante (índice de Barthel 21,52, Palliative Performance Scale 38,18). La cuidadora principal fue mayoritariamente mujer, hija del paciente y con sobrecarga para los cuidados en el 55,4%. Del grupo sin afectación cognitiva, un 83% conocían el diagnóstico, un 30% el pronóstico, el 95% preferían el domicilio para los cuidados y mantenían esta preferencia para el fallecimiento el 78%. El 66% del total de los pacientes falleció en domicilio/residencia. El análisis de los posibles factores relacionados con la muerte en el domicilio mostró resultados significativos cuando el ámbito geográfico para el cuidado era el medio rural y el paciente había manifestado su preferencia por fallecer en el domicilio. También cuando el cuidador principal no mostraba sobrecarga y tenía una percepción subjetiva de buena salud. CONCLUSIONES: Se identificó una población de PNO en situación de enfermedad avanzada caracterizada por edad elevada, alta carga sintomática, importante comorbilidad, deterioro funcional y alta mortalidad. Más de la mitad de los cuidadores presentaron sobrecarga para los cuidados. Se trata, por tanto, de enfermos con necesidades similares a las de los pacientes oncológicos avanzados. La prevalencia elevada de deterioro cognitivo supuso que solo la mitad de los pacientes fueron capaces de participar en la información y en la toma de decisioneS

OBJECTIVE: To describe the socio-demographic and clinic characteristics and aspects related to information of non-oncological patients (NOP) with advanced disease, which are included in a palliative-home care support unit. To identify the variables that could be associated with the death of NOP at home. MATERIAL AND METHOD: A retrospective descriptive study was performed by reviewing the clinical histories of NOP attended by a Palliative-home Care Support Unit during the period from November 2009 to March 2013. An analysis was performed on the socio-demographic and clinical data of the patients and their main caregivers, as well as the analysed, diagnostic and prognostic information provided by the family and the patient, preferences about end of life care of both parties, and the place of death. The data analysis was performed with the computer pack SPSS(R) v.21. RESULTS: Of the 371 clinical histories reviewed, 249 patients met the inclusion criteria. The NOP represented the 36.19% of the activity, with a mean age of 81.4 years. The most common disease was dementia (22.1%). More than two-thirds (67.5%) of the patients came from Primary Care and residential homes for the elderly. The main reason for referral was to control symptoms in 85.5%, with the most frequent being asthenia, dyspnoea, and pain. A high comorbidity, geriatric symptoms, cognitive impairment was observed in 65%, and an important functional impairment (mean Barthel Index of 21.52, and Palliative Performance Scale score of 38.18). The majority of main caregivers were women, and the patient's daughter, and the burden of caring was identified in 55.4%. In the group without cognitive impairment, the diagnosis was known by 83%, and 30% knew the prognosis. Staying at home to receive end of life care was preferred by 95%, and 78% kept this preference for dying. Two-thirds (66%) of all the patients died at home or in residential homes for the elderly. The statistical analysis of the possible factors associated with dying at home showed a significant odds ratio when the patient lived in rural areas, and preferred home as the place of death. Another factor is when the main caregiver does not suffer care burden and has a subjective perception of good health. CONCLUSIONS: The predominance of NOP in end of life situations is characterised by advanced age, high comorbidity, increased symptomatic burden, significant overall functional impairment on admission, and high mortality. More than the half of the caregivers showed excessive burden of caring. In conclusion, they are patients with similar needs to those with advanced oncological disease. The high prevalence of cognitive impairment suggested that only half of the patients were able to participate in the information and in the advanced care planning

Debranching aortic surgery.

Conventional open surgery still remains as the gold standard of care for aortic arch and thoracoabdominal pathology. In centers of excellence, open repair of the arch has been performed with 5% immediate mortality and a low rate of complications; however overall mortality rates are around 15%, being up to 40% of all patients rejected for treatment due to their age or comorbidities. For thoracoabdominal aortic pathology, data reported from centers of excellence show immediate mortality rates from 5% to 19%, spinal cord ischemia from 2.7% to 13.2%, and renal failure needing dialysis from 4.6% to 5.6%. For these reasons, different alternatives that use endovascular techniques, including debranching procedures, have been developed. The reported results for hybrid debranching procedures are controversial and difficult to interpret because series are retrospective, heterogenic and including a small number of patients. Clearly, an important selection bias exists: debranching procedures are performed in elderly patients with more comorbidities and with thoracoabdominal aortic aneurysms that have more complex and extensive disease. Considering this fact, debranching procedures still remain a useful alternative: for aortic arch pathology debranching techniques can avoid or reduce the time of extracorporeal circulation (ECC) or cardiac arrest which may be beneficial in high-risk patients that otherwise would be rejected for treatment. And compared to pure endovascular techniques, they can be used in emergency cases with applicability in a wide range of anatomies. For thoracoabdominal aortic aneurysms, they are mainly useful when other lesser invasive endovascular options are not feasible due to anatomical limitations or when they are not available in cases where delaying the intervention is not an option.

Hybrid aortic repair with antegrade supra-aortic and renovisceral debranching from ascending aorta.

Aortic dissection is a life threatening condition. Hybrid repair has been described for the treatment of complex aortic pathology such as thoracoabdominal aortic aneurysms (TAAA) and type A and B dissections, although open and total endovascular repair are also possible. Open surgery is still associated with substantial perioperative morbi-mortality rates, thus less invasive techniques such as endovascular repair and hybrid procedures can achieve good results in centers with experience. We present the case of a patient with a chronic type B dissection and TAAA degeneration that was treated in a single stage hybrid procedure with antegrade supra-aortic and renovisceral debranching from the ascending aorta and TEVAR. At three-year follow up, the patient is free of intervention-related complications.
