RESUMEN

BACKGROUND: Contrast-induced nephropathy (CIN) is a major inconvenience in the use of iodinated contrast media (ICM) and it is associated with a significant increase in morbidity and mortality and cost of hospitalization. Remote ischemic preconditioning (RIPC) is a noninvasive and cost-effective tissue protection technique that has showed to be beneficial in decreasing renal insult in patients receiving intravascular contrast. AIM: The primary outcome of this study is to evaluate the impact of RIPC on the incidence of CIN in patients undergoing endovascular aneurysm repair. METHODS: Patients suffering from aortic aneurysm were recruited prior to the administration of ICM. Randomization was used to assign patients into the control/RIPC groups. Biochemical parameters determined renal function before and after surgery in immediate (24-72 hr) and at 30 days of follow-up. RESULTS: Of the 120 patients included in the study, 98,3% were male. Mean age was 73 years (range: 56-87 years). Diabetes and chronic renal failure (considering estimated glomerular filtration [eGFR] <60) was present prior to administration of ICM in 29.16% and 38.33%, respectively. RIPC was applied in 50% (n = 60) of the patients. A total of 24.17% developed CIN regardless of fluidotherapy, RIPC, and other protective strategies. RIPC did not influence outcomes in terms of incidence on CIN, serum creatinine, urea, eGFR, or microalbuminuria in immediate postoperative period. However, the group of RIPC patients showed a statistically significant benefit in renal function in terms of serum creatinine (1.46 ± 0.3 vs. 1.03 ± 0.5; P < 0.001), urea (61.06 ± 27.5 mg/dL vs. 43.78 ± 12.9 mg/dL; P = 0.003), and an increase in eGFR (56.37 ± 23.4 mL/min/1.73 m2 vs. 72.85 ± 17.7 mL/min/1.73 m2; P = 0.004) at 30 days of follow-up. CONCLUSIONS: RIPC seems to be a reasonable, effective, and low-cost technique to alleviate effects of ICM on the renal parenchyma in endovascular aneurysm repair procedures during short-term postoperative period.

RESUMEN

INTRODUCTION: Public health was severely affected by the first wave of the COVID-19 pandemic, imposing major daily life changes across the world, including health services that had to restructure significantly. REPORT: Considering the potential side effects on the quality of vascular training, a digital survey (Survey Monkey®) was developed and submitted to vascular trainees from 7 July to 20 September 2020 through European mailing lists and social media platforms. The aim was to evaluate the standpoint of vascular education across Europe during the first wave of the COVID-19 pandemic and to identify possible measures to mitigate the negative effects on vascular trainees. A total of 104 answers across 27 European countries were received. The mean age of the responders was 31.2 ± 3.58 years, of whom 60.6% were male. Forty-four (42.3%) of the vascular trainees actively participated on the COVID-19 front line; 76.9% of them reported a decrease in surgical procedures performed and/or assisted, with 60% reporting a reduction >50%. Emergency procedures were the only surgical activities for 7.5% of the trainees. Annual or final examinations were re-scheduled or cancelled for 16.3% and 10.6% of the participants, respectively. According to the survey, 73.5% of the responders claimed that the first wave of the COVID-19 pandemic had a negative impact on vascular education and 73.4% agreed the need for "compensation measures" to be taken. DISCUSSION: The first wave of the COVID-19 pandemic brought a significant negative impact on vascular education. Considering an extended pandemic situation, it is believed that compensatory measures should be addressed to maintain the high standards of vascular education and develop new educational tools for future trainees.

RESUMEN

BACKGROUND: A pro-inflammatory state and a poor nutritional status have been associated with severity and prognosis of patients with peripheral arterial disease (PAD). The clinical applicability of the different pre-operative nutritional and inflammatory biomarkers in patients with critical limb-threatening ischemia (CLTI) was analyzed. METHODS: A retrospective observational study was performed, that included all patients with CLTI revascularized from January 2016 to July 2019. The inflammatory state was calculated using neutrophil/lymphocyte (NLR), lymphocyte/monocyte (LMR) and platelet/lymphocyte ratios (PLR). For nutritional status, the Prognostic Nutritional Index (PNI) was calculated. Mortality and number of major amputations at 6 months and hospital length-of stay were studied. RESULTS: 310 patients were included. Higher levels of NLR and lower levels of PNI were associated with mortality (6.61±5.6 vs. 3.98±3.27, P=0.034; 40.33±7.89 vs. 45.73±7.48, P=0.05, respectively). Lower levels of PNI and LMR (42.57±7.82 vs. 45.44±7.65, P=0.036; 2.77±1.61 vs. 3.22±1.75, P=0.013, respectively) and higher levels of NLR (6.91±7.85 vs. 3.94±2.57, P=0.023) were associated with major amputations. The mean hospital length-of-stay was higher in patients with lower levels of PNI and LMR (P=0.000 and P=0.003) and higher levels of NLR and PLR (P=0.001 and P=0.002). A PNI<42.87 predicted short-term mortality with a 66.7% of sensitivity and a 66.8% of specificity (P=0.000). CONCLUSIONS: Our experience suggests that these inflammatory and nutritional biomarkers are independent predictors of short-term mortality and major amputations. In addition, our results suggest that PNI could be used to predict the short-term mortality with high sensitivity and specificity.

RESUMEN

This dataset supports the findings of the vascular e-Learning during the COVID-19 pandemic survey (the EL-COVID survey). The General Data Protection Regulation (GDPR) of the European Union was taken into consideration in all steps of data handling. The survey was approved by the institutional ethics committee of the Primary Investigator and an online English survey consisting of 18 questions was developed ad-hoc. A bilingual English-Mandarin version of the questionnaire was developed according to the instructions of the Chinese Medical Association in order to be used in mainland People's Republic of China. Differences between the two questionnaires were minor and did affect the process of data collection. Both questionnaires were hosted online. The EL-COVID survey was advertised through major social media. All national and regional contributors contacted their respective colleagues through direct messaging on social media or by email. Eight national societies or groups supported the dissemination of the EL-COVID survey. The data provided demographics information of the EL-COVID participants and an insight on the level of difficulty in accessing or citing previously attended online activities and whether participants were keen on citing these activities in their Curricula Vitae. A categorization of additional comments made by the participants are also based on the data. The survey responses were filtered, anonymized and submitted to descriptive analysis of percentage.

RESUMEN

BACKGROUND: The corona virus disease (COVID-19) pandemic has radically changed the possibilities for vascular surgeons and trainees to exchange knowledge and experience. The aim of the present survey is to inventorize the e-learning needs of vascular surgeons and trainees as well as the strengths and weaknesses of vascular e-Learning. METHODS: An online survey consisting of 18 questions was created in English, with a separate bilingual English-Mandarin version. The survey was dispersed to vascular surgeons and trainees worldwide through social media and via direct messaging from June 15, 2020 to October 15, 2020. RESULTS: Eight hundred and fifty-six records from 84 different countries could be included. Most participants attended several online activities (>4: n = 461, 54%; 2-4: n = 300, 35%; 1: n = 95, 11%) and evaluated online activities as positive or very positive (84.7%). In deciding upon participation, the topic of the activity was most important (n = 440, 51.4%), followed by the reputation of the presenter or the panel (n = 178, 20.8%), but not necessarily receiving accreditation or certification (n = 52, 6.1%). The survey identified several shortcomings in vascular e-Learning during the pandemic: limited possibility to attend due to lack of time and increased workload (n = 432, 50.5%), no protected/allocated time (n = 488, 57%) and no accreditation or certification, while technical shortcomings were only a minor problem (n = 25, 2.9%). CONCLUSIONS: During the COVID-19 pandemic vascular e-Learning has been used frequently and was appreciated by vascular professionals from around the globe. The survey identified strengths and weaknesses in current e-Learning that can be used to further improve online learning in vascular surgery.

RESUMEN

BACKGROUND: The aim of this study was to analyze duplex ultrasound (DUS) and intraoperative angiography concordance for diagnosis of lower limb peripheral artery disease and its value for surgical planning. MATERIALS AND METHODS: This was a prospective, observational study, including patients who underwent revascularization of the lower limbs during 2018, diagnosed by DUS only or combined with preoperative computed tomography (CT) angiography. The concordance between preoperative DUS or CT angiography and the intraoperative angiography was studied using the Cohen kappa coefficient (k). The degree of agreement between the DUS-based surgical plan and the final surgical technique was also evaluated. RESULTS: Fifty-one patients were included, with mean age of 71.8 ± 11.96 years (46-94); 23 had chronic kidney disease (45%). In 17 patients (34%), preoperative CT angiography was also performed. DUS showed a sensitivity of 100% (95% confidence interval (CI) [83.3-100%]), 80% (95% CI [50.21-100%,]), and 100% (95% CI [96.43-100%]) at the iliac, femoral, and popliteal sector, respectively, and a specificity of 93.55% (95% CI [83.29-100%]), 95.45% (95% CI [84.48-100%]), and 90.48% (95% CI [75.54-100%]) at the iliac, femoral, and popliteal sector, respectively. The positive predictive value for DUS was 60% (95% CI [7.06-100%]), 88.9% (95% CI [62.8-100%]), and 87.5% (95% CI [68.17-100%]) for the iliac, femoral, and popliteal sectors, respectively, whereas the negative predictive value was 100% (95% CI [98.28-100%]), 91.3% (95% CI [77.61-100%]), and 100% (95% CI, [97.37-100%]). The concordance between DUS and intraoperative angiography showed a k index of 0.587 (P = 0.000) in the iliac sector, 0.799 in the femoral sector (P = 0.000), and 0.699 in the popliteal sector (P = 0.000). The concordance between CT angiography/intraoperative angiography had a k index of 0.71 in the iliac sector (P = 0.0093), 0.566 in the femoral sector (P = 0.006), and 0.5 in the popliteal sector (P = 0.028). DUS-based surgical plan was accurate in 86% of cases (n = 44). CONCLUSIONS: Our experience suggests that DUS arterial mapping of the femoral and popliteal areas is better than CT angiography and can be considered as a unique preoperative imaging test during the surgical planning in patients undergoing a lower limb revascularization procedure.

RESUMEN

A 50-year-old male patient, without a previous medical history, presented sudden severe abdominal pain with no alterations in the blood analysis. A CT-Angiography (CTA) was performed that showed a wall thickening of the celiac trunk extended to the hepatic artery with a filiform lumen and no involvement of the splenic artery. There were no signs of intestinal or liver ischemia, therefore no further radiological tests were performed. The proteinogram and serology were normal, with no immunological and acute phase reactant markers, excluding vasculitis. It appeared as an isolated lesion with no signs of arterial dissection or pseudoaneurysms of the remaining abdominal vessels or the aorta. Therefore, it was considered as a Segmental Arterial Mediolisis (SAM).

RESUMEN

Nonanastomotic pseudoaneurysm formation after vascular reconstruction is a rarely encountered problem. Covered stent graft constitutes a minimal approach. To our knowledge, the present study constitutes the first case of implantation of Solaris stent graft in Europe. A 69-year-old man with severe cardiac dysfunction presented a pseudoaneurysm of a popliteal to popliteal artery reversed saphenous vein bypass graft. The patient was successfully treated by the percutaneous placement of a Solaris self-expanding covered stent. The postimplantation arteriogram demonstrated exclusion of the pseudoaneurysm, complete apposition of the stent, and adequate runoff. No complications occurred, and the patient was discharged from the hospital one day later receiving 75 mg of clopidogrel. Endovascular exclusion by covered stent deployment offers a safe, rapid, and minimally invasive alternative to open surgical resection in patients with lower limb venous graft pseudoaneurysm. The Solaris covered stent provides a new catheter-based device with adequate navigability and exceptional accurate delivery system.

RESUMEN

OBJECTIVE: The objective of this study was to determine the influence of hemodynamic force on the development of type III endoleak and branch thrombosis after complex endovascular thoracoabdominal aortic aneurysm repair. METHODS: Patients with thoracoabdominal aortic aneurysm, within surgical range, treated with a fenestrated or branched endovascular aneurysm repair from 2014 to 2018 and with 3-month control computed tomography angiography were selected. Demographic variables, aneurysm anatomy, and endograft conformation were analyzed retrospectively from a prospective registry. The hemodynamic force was calculated using the mass and momentum conservation equations. RESULTS: Twenty-eight patients were included; the mean follow-up period was 24.7 ± 19.3 months. There were 102 abdominal vessels successfully catheterized (19 celiac arteries, 29 superior mesenteric arteries, 27 right renal arteries, 26 left renal arteries, and 1 polar renal artery). The rate of type III endoleak was 11.5% (n = 12); six cases were associated with branches that received two stents (P < .001). A higher rate of endoleak was observed with wider stents (8.50 ± 1.0 mm vs 7.17 ± 1.3 mm; P = .001) but not with longer stents (P = .530). All cases of type III endoleak affected visceral arteries (eight celiac arteries and four superior mesenteric arteries). The freedom from type III endoleak at 24 months was 86%. The rate of thrombosis was 5.9% (n = 6). A higher rate of thrombosis was observed in smaller vessels (5.00 ± 1.3 mm vs 7.16 ± 1.8 mm; P = .001), with higher stent oversizing (36.87% ± 23.6% vs 5.52% ± 15.0%; P < .001), and with a higher angle of curvature (124.33 ± 86.1 degrees vs 57.71 ± 27.9 degrees; P < .001). All cases of thrombosis were related to renal arteries (two left renal arteries, two right renal arteries, and two polar renal arteries). The freedom from thrombosis at 24 months was 92%. The area under the curve for the angle of curvature was 0.802 (95% confidence interval, 0.661-0.943; P = .013), and the cutoff point was established at 59.5 degrees (sensitivity, 100%; specificity, 60.4%). The receiver operating characteristic curve for the stent oversize showed an area under the curve of 0.903 (95% confidence interval, 0.821-0.984; P = .001), and the cutoff point was 14.5% (sensitivity, 100%; specificity, 77.1%). A higher hemodynamic force was associated with thrombosis (23.35 × 10-3 N ± 18.7 × 10-3 N vs 12.31 × 10-3 N ± 6.8 × 10-3 N; P = .001) but not with endoleak (P = .796). The freedom from endoleak and thrombosis at 24 months was 86% and 90%, respectively. CONCLUSIONS: Longer stents should be preferred to avoid type III endoleak. A higher angle of curvature leads to a higher hemodynamic force that results in a higher rate of thrombosis. Accordingly, we recommend maintaining the angle of curvature under 59.9 degrees. Small vessels and excessive stent oversizing entail a higher risk of thrombosis; as such, we advise a maximum stent oversize of 14.5%. Renal arteries are more susceptible to thrombosis, whereas visceral arteries are more prone to endoleak.

RESUMEN

BACKGROUND: Reports our experience for the first 50 cases of use of Supera stent for popliteal atherosclerotic lesions treatment. METHODS: This prospective single-arm trial enrolled the first 50 limbs (46 patients) treated in our center with a Supera stent for symptomatic atherosclerotic disease of the popliteal artery. Also, a follow-up of 36 months is reported. RESULTS: The mean preoperative ankle-brachial index increased from 0.38 ± 0.37 before intervention to 0.63 ± 0.46 postoperatively at 12 months (P = 0.014), 0.66 ± 0.39 at 24 months (P = 0.023), and 0.74 ± 0.46 at 36 months (P = 0.029). Primary patency at 12, 24, and 36 months were 89.6%, 72.3%, and 70.2%, and primary assisted patency was 93.8%, 87.2%, and 85.1%, respectively, by Kaplan-Meier estimates. After 3 years of follow-up, age <75 years (P = 0.034) and Trans-Atlantic Inter-Society Consensus (TASC)-II D lesions (P = 0.041) constituted risk factors for stent occlusion. During the follow-up of the patients, none of them developed stent fracture as evidenced on plain radiographs during follow-up. Implantation defects did not constitute a risk factor for stent restenosis. CONCLUSIONS: Based on the results of this study, Supera stent has shown an excellent 3-year patency in this difficult-to-treat anatomic segment. In our experience, younger patients and complex lesions (TASC-II type D) were positive significant predictors for restenosis. In our cohort, post deployment stent conformation did not influence patency. Nevertheless, further investigations, including randomized studies comparing the Supera stent with other stent platforms, drug eluting angioplasty, or atherectomy devices, are mandatory.

RESUMEN

Type II endoleak relates to aneurysm perfusion through a patent branch vessel. Reintervention for type II endoleak should be considered in the presence of significant aneurysm growth. Recurrences and subsequent reinterventions are frequent by occult type II endoleaks through feeder arterial branches. We report a case of a patient with a type II endoleak due to inferior mesenteric artery (IMA) patency associated with aneurysm sac growth after an unsuccessfully attempt of transarterial embolization. Laparoscopic ligation of the IMA with direct sac puncture embolization was performed. The postoperative and 1-year follow-up computed tomography angiography scan demonstrated no endoleak signs and aneurysm sac shrinkage. The proposed modification of this technique constitutes a novel approach to this entity. Total laparoscopic IMA ligation and direct sac puncture embolization technique may increase the success rate for the treatment of endoleaks type II by excluding the recurrences. This technique may offer a safe, feasible, and minimally invasive approach for type II endoleaks when other endovascular techniques are unsuccessful.

RESUMEN

INTRODUCTION: Median arcuate ligament syndrome (MALS) is an uncommon condition caused by the extrinsic compression of the celiac trunk (CT) and celiac ganglion, secondary to an anatomical abnormality of the median arcuate ligament fibers. It is characterized by postprandial epigastric pain, chronic abdominal pain, weight loss, nausea and vomiting. MALS is typically diagnosed after the exclusion of other, more common conditions; however, a variety of imaging and diagnostic modalities, including Duplex ultrasonography, computed tomography angiography, magnetic resonance angiography, gastric tonometry and angiography can suggest findings consistent with MALS. EVIDENCE ACQUISITION: Laparoscopic approach has been proposed as the option of choice for the treatment of these patients. A systematic review of the international literature regarding this modality of treatment is presented here. EVIDENCE SYNTHESIS: The review included 504 cases, and several principles are suggested to improve the management. The advantages of this minimally invasive technique include short operative time (136.0 minutes, range 70-242), shorter hospital stay (3.8 days, range 0.5-7) and low rate of conversion to open surgery (4.2%). CONCLUSIONS: Various treatment modalities are available to decompress the celiac trunk. Although open surgery has been traditionally accepted as the gold standard, laparoscopic division of the MALS has proven equal results. Others have described different treatment modalities, including bypass surgery and endovascular procedures (angioplasty or stent placement). Laparoscopic approaches to correct MALS are feasible and safe. It may be the preferred modality of treatment in view of its lack of morbidity, shorter hospital stay and good results.

RESUMEN

INTRODUCCIÓN Y OBJETIVO: se han descrito diferencias en la prevalencia de la enfermedad arterial periférica (EAP) en distintas áreas geográficas. El objetivo es analizar los pacientes de Europa del este intervenidos en nuestro centro de isquemia crónica de extremidades inferiores y compararlos con los de origen español para describir cómo puede influir la etnia en el desarrollo de la EAP. MATERIALES Y MÉTODOS: se ha escogido una muestra de 337 pacientes intervenidos en nuestro centro desde el 2007 hasta el 2017 diagnosticados de isquemia arterial crónica de extremidades inferiores. Se han analizado los factores de riesgo cardiovascular (FRCV), la clínica al ingreso, las lesiones TASC y la estancia hospitalaria media. RESULTADOS: los pacientes de Europa del este representan el 7,7% de la muestra. La media de edad es de 67,9 años y un 79,8% son varones: el 70% presenta HTA; el 45,4%, DM; el 52,5%, DLP y el 40,7% son fumadores. Respecto a las comorbilidades, el 30,6% presenta cardiopatía isquémica; el 13,6%, EPOC y un 7,4%, accidentes cerebrovasculares. Los pacientes de Europa del este son más jóvenes (53,5 ± 10,53 frente a 69,09 ± 10,77; p = 0,0001), con menor prevalencia del resto de FRCV (HTA 30,7% frente al 73,3%, p = 0,001; DM 23,07% frente a 47,27%; p = 0,017; DLP 30,77% frente al 54,34%; p = 0,021). La prevalencia de fumadores es mayor (80,77% frente a 69,45%; p = 0,002). Presentan una clasificación Rutherford menor y un ITB más alto (3,19 ± 0,85 frente a 3,73 ± 1,19, p = 0,03, y 0,41 ± 0,21 frente a 0,26 ± 0,06, p = 0,028, respectivamente). La mayoría de los pacientes de Europa del este son claudicantes y presentan una estancia media superior que los pacientes claudicantes de origen español (12,31 frente a 6,3 días; p < 0,001). No existen diferencias significativas en el grado TASC. CONCLUSIONES: los pacientes de Europa del este intervenidos de isquemia arterial crónica de extremidades inferiores son más jóvenes, más fumadores y con menor prevalencia del resto de FRCV. La mayoría presenta claudicación intermitente y tiene una estancia hospitalaria media más elevada que los pacientes españoles


INTRODUCTION AND OBJECTIVE: differences in the prevalence of peripheral arterial disease (PAD) have been described in different geographical areas. These differences have been justified by life habits and socio-economic development of a country. The aim of this study is to analyze eastern Europe patients and Spanish patients, who underwent surgical procedures of lower limb chronic ischemia, to describe how can influence ethnicity in the PAD development. MATERIALS AND METHODS: a sample of 337 operated patients of lower extremities chronic ischemia in our center from 2007 to 2017 has been chose. Cardiovascular risk factors (CVRF), clinic at the beginning of admission, TASC lesions in imaging tests and hospitalization days were analyzed. RESULTS: eastern Europe patients represent 7.7% of the sample. The average age is 67.9 years (22-97) and 79.8% are males. 70% have HTA, 45.4% DM, 52.5% DLP and 40.7% are smokers. Regarding comorbidities: 30.6% have ischemic heart disease, 13.6% OCPD and 7.4% cerebrovascular disease. Eastern Europe patients are younger than Spanish patients (53.5 ± 10.53 vs. 69.09 ± 10.77) and with a lower prevalence of the rest of CVRF (HTA 30.7% vs. 73.3%; DM 23.07% vs. 47.27%; DLP 30.77% vs. 54.34%). In addition, the prevalence of smokers is higher (80.77% vs. 69.45%). They also present a lower Rutherford classification and a higher ABI (3.19 ± 0.85 vs. 3.73 ± 1.19 and 0.42 vs. 0.26, respectively). The average stay is higher in claudicants eastern Europe's patients (12.31 vs. 6.3 days). CONCLUSIONS: operated eastern European patients of lower limb chronic ischemia are young patients, smokers, and have a lower prevalence of the rest of CVRF. More than half of eastern Europe patients present intermittent claudication and they have a higher hospital stay than claudicant Spanish patients

RESUMEN

The Supera peripheral stent system has a woven wire design that may confer a potential advantage and has higher resistive radial strength of traditional stents, which gives it the ability to avoid kinking. Because a stent is a permanent implant in the target vessels and they would be subjected to a wide variety of torsion, compression, and stress, a rupture is not surprising. Only three cases of ruptured Supera stents have been published in literature. We present a case of P2 popliteal segment thrombosis secondary to Supera stent fracture. A 51-year-old male patient presented with lifestyle-limiting intermittent claudication after 6 months of popliteal recanalization and Supera stent implantation. The computed tomography angiography demonstrated a popliteal artery occlusion secondary to stent fracture. The lesion was satisfactorily treated by endovascular recanalization and with a new Supera stent deployment. The duplex examination after 3 and 6 months demonstrated stent's permeability, and the plain anteroposterior and lateral radiographs did not reveal new stent fractures. Our data suggested that Supera stents are not free of fractures during follow-up and their treatment depends on the type of fracture, with the possibility for endovascular treatment in type III fractures.
