RESUMO

AIM: Our aim is to analyze the ability of distal endovascular procedures, performed as first treatment option, to promote ischemic ulcer healing. METHODS: Retrospective analysis of 91 primary distal procedures, 49 (53.8%) surgical and 42 (46.2%) endovascular, performed consecutively between January 2005 and December 2007 in patients with critical limb ischemia (CLI) and ischemic ulcers. Patient comorbidities, intervention duration time, postoperative hospital stay and complications were recorded. Ischemic ulcer healing time, patency, limb salvage and survival rates were compared between both groups. Data were included in a Cox regression model to determine predictive factors for healing RESULTS: Endovascular therapy was associated with shorter intervention time (128±53 versus 301±91 min; P=0.001) and postoperative hospital stay (13±13 versus 19±14 days; P=0.05). Surgical procedures were associated with more local complications (28.6% versus 7.1% P=0.01), more readmissions for surgical wound complications (12.2% versus 0% P=0.03) and more early major amputations (16.3% versus 0% P=0.007). Ischemic ulcer healing in endovascular and surgical procedures was 80% versus 83% at 12 months (P=NS). Overall patency, limb salvage, survival and amputation-free survival with healed ulcers at 24 months in endovascular and surgical groups were 82% versus 82% (P=NS), 83% versus 72% (P=NS), 81% versus 79% (P=NS) and 63% versus 56% (P=NS). Diabetes mellitus (HR: 2.86 95% CI [1.44-5.68]), free ambulatory status (HR: 0.57 95% CI [0.33-0.98]) and the presence of severe wounds (HR: 2.73 95% CI [1.40-5.30]) were predictors for ulcer healing. CONCLUSION: Endovascular and surgical distal procedures had a similar ulcer healing rate and limb salvage. Our experience supports endovascular-first strategy for CLI with tissue loss.

RESUMO

Objetivo. Presentar una excepcional asociación, en un varón joven, entre pioderma gangrenoso, acné conglobata,infarto de miocardio y embolia aortoilíaca, analizando sus posibles relaciones etiopatogénicas. Caso clínico. Varónde 25 años con clínica de isquemia arterial aguda en la extremidad inferior derecha. Como antecedentes, presentabaacné conglobata diseminado en tórax, abdomen y extremidades, y pioderma gangrenoso con tratamiento crónico corticoideode más de 12 años de duración. En el electrocardiograma se apreciaron imágenes sugestivas de infarto de miocardioantiguo silente y trombos apicales intracavitarios en el ecocardiograma, confirmados en resonancia cardíaca. Sele practicó tromboembolectomía de ambos miembros inferiores, en dos tiempos, y se obtuvo un buen resultado morfológicoy clínico, por lo que se asumió el riesgo del acceso quirúrgico a través de las lesiones ulceradas, por la posibilidadde infección y del fenómeno de patergia, característico del pioderma. Conclusiones. Los procesos inflamatorios crónicoshan sido relacionados con estados de trombofilia, que podrían deberse a mecanismos autoinmunes. El pioderma está frecuentementeasociado a enfermedades sistémicas, como las enfermedades inflamatorias intestinales, que a su vez han sidorelacionadas con complicaciones trombóticas. El tratamiento crónico con corticoides, que mantenía el paciente, producealteraciones en el electrocardiograma y enfermedad isquémica cardíaca. Sea como asociación sistémica no descrita,o como proceso protrombótico multicausal, los trombos intracavitarios asociados al infarto de miocardio fueron loscausantes de la isquemia


Aims. To present an exceptional association, in a young male, of pyoderma gangrenosum, acne conglobata,myocardial infarct and aortoiliac embolism, and to analyse their possible aetiopathogenic relations. Case report. Westudied the case of a 25-year-old male with a clinical picture of acute arterial ischaemia in the right lower limb. Thepatient had a history of disseminated acne conglobata on his thorax, abdomen and limbs, and had been receivingcorticoid treatment for pyoderma gangrenosum for over 12 years. An electrocardiogram revealed images suggesting aprevious silent myocardial infarct and the echocardiogram showed intracavitary apical thrombi, which were confirmed inthe cardiac magnetic resonance scan. A thromboembolectomy was performed in both lower limbs, in two sessions, and agood morphological and clinical result was obtained; the decision was therefore made to risk taking a surgical approachvia the ulcerated lesions, due to the possibility of infection and the phenomenon of pathergy, which is characteristic inpyoderma. Conclusions. Chronic inflammatory processes have been related to thrombophilic states, which could be dueto autoimmune mechanisms. Pyoderma is often associated with systemic diseases, such as inflammatory bowel diseases,which have in turn been linked to thrombotic complications. Chronic treatment with corticoids, which is what maintainedthe patient, produces alterations in the electrocardiogram and ischaemic heart disease. Whether as a systemic associationthat has not yet been described or as a prothrombotic process with multiple causation, the intracavitary thrombiassociated with the myocardial infarct were the cause of the ischaemia

RESUMO

Introducción. Los trombos en la aorta torácica son poco frecuentes y constituyen una importante fuente de embolismos.El tratamiento endovascular ha mejorado las opciones terapeúticas hasta ahora reservadas a la tromboendarterectomíay/o a la anticoagulación sistémica. Caso clínico. Mujer de 52 años, fumadora, derivada desde otro centro pordolor abdominal difuso, náuseas, vómitos y hallazgo en la tomografía computarizada abdominal de oclusión de la arteriailíaca común izquierda, infartos renales bilaterales y defecto de repleción en la porción inferior de la aorta torácica.En el ecocardiograma transesofágico se observaba un trombo móvil de 7 × 23 mm en la aorta torácica. Se instauró el tratamientocon anticoagulación en dosis terapéuticas y se realizó una angiorresonancia magnética y una arteriografía; comoresultado de estas pruebas se observó un trombo flotante en la aorta torácica de 3 cm de longitud, fijado a la placaateroesclerótica, oclusión de la arteria renal izquierda e ilíaca izquierda. La exclusión del trombo se realizó mediante laliberación en la aorta torácica de una endoprótesis de 32 × 112 mm (Relay ®, Bolton Medical España), con acceso aórticoabdominal a través de una prótesis de dacron de 8 mm y un bypass aortofemoral izquierdo posterior (arteria ilíacacomún < 0,7 cm de diámetro). En la arteriografía de control intraoperatoria no se objetivaron imágenes de fuga ni defectosde repleción en la aorta torácica. La angiotomografía postoperatoria confirmó la exclusión del trombo. Se dio de altaa la paciente con tratamiento antiagregante; seis meses después de la intervención se encontraba asintomática. Conclusión.El tratamiento endovascular de estas lesiones constituye una nueva alternativa de tratamiento efectiva y seguray con menores tasas de morbimortalidad perioperatoria


Introduction. Thrombi rarely occur in the thoracic aorta and constitute an important source of embolisms.Endovascular treatment has improved the therapeutic options, which until recently were limited to thromboendarterectomyand/or systemic anticoagulation. Case report. A 52-year-old female smoker, who was referred from another health centrebecause of diffuse abdominal pain, nausea and vomiting; the findings from a computerised tomography scan of theabdomen showed occlusion of the left common iliac artery, bilateral renal infarction and filling defect in the lowerportion of the thoracic aorta. A transthoracic echocardiogram showed a 7 × 23 mm mobile thrombus in the thoracicaorta. Anticoagulation treatment was established in therapeutic doses and magnetic resonance angiography andarteriography were performed. The results of these tests revealed a 3 cm long floating thrombus in the thoracic aorta,which was attached to the atherosclerotic plaque, and occlusion of the left renal and left iliac arteries. Exclusion of the thrombus was performed by deploying a 32 × 112 mm stent (Relay ®, Bolton Medical España) in the thoracic aorta, withabdominal aortic access via an 8 mm Dacron graft and a posterior left aortofemoral bypass (common iliac artery < 0.7 cmin diameter). In the intraoperative control arteriography, no leaks or filling defects were observed in images of thethoracic aorta. The post-operative angiotomography confirmed the exclusion of the thrombus. The patient was dischargedfrom hospital with antiplatelet treatment; six months after the operation she remained asymptomatic. Conclusions. Theendovascular treatment of these lesions represents a new therapeutic alternative that is safe and effective and which haslower perioperative morbidity and mortality rates (AU)

RESUMO

Introducción. El tratamiento endovascular en el sector iliaco, que comenzó a aplicarse en pacientes de alto riesgo,hoy día puede ser la primera opción terapéutica. Objetivo. Determinar los resultados de la angioplastia transluminalpercutánea en el sector iliaco, con o sin implantación de stent, estratificando el análisis según tipos de lesión TASC-2000 yestimar la influencia de factores pronósticos en la permeabilidad, la salvación de la extremidad y la supervivencia. Pacientesy métodos. Análisis retrospectivo de 101 procedimientos en 91 pacientes, 85/6 hombres/mujeres) con una edad media de61,54 ± 11,59 años. Factores de riesgo: diabetes, 41,6%; hipertensión, 41,6%; tabaquismo, 56,4%; cardiopatía isquémica,19,8%; insuficiencia renal, 9,9%. La indicación fue en 35,7% isquemia crítica y claudicación limitante en 61,4%. Lesión tipoTASC A: 44,6%, B: 42,6%, C: 10,9%, D: 1,98%. Técnica: angioplastia, 35,65% y stent, 64,35%. Todas las variables, métodosde evaluación clínica y hemodinámica se definieron según los criterios de la SVS/ISCVS. Resultados. A los 66 meses,las tasas de permeabilidad primaria fueron del 69,84%, secundaria del 80,64%, salvación de la extremidad del 81,5% y supervivenciadel 93,6%. Resultados precoces: 4 fracasos técnicos, éxito morfológico del 92,1% y clínico del 85,1%. No se registraronfallecimientos ni amputaciones. A los 66 meses, estratificando según TASC, las permeabilidades primarias morfológicasy clínicas, respectivamente, fueron: A: 75,09%, 63,65%; B: 68,07%, 69,66% y secundarias: A: 89,98%, 73,30%; B:81,03%, 83,14%. El factor pronóstico significativo de disminución de permeabilidad primaria fue la localización en iliacaexterna, y para tasas de salvación de extremidad y supervivencia la insuficiencia renal. Actualmente, el tratamiento endoluminaliliaco, gracias a los avances tecnológicos, los excelentes resultados y la baja morbimortalidad, puede ser la primeraalternativa terapéutica para estos pacientes. Conclusiones. El tratamiento endovascular en el sector iliaco es aplicable a estetipo de pacientes, con uso selectivo de stent, obteniendo resultados similares a otras series


Introduction. Endovascular treatment of the iliac sector, which was first applied to high-risk patients, cannow be the preferred therapeutic option today. Aim. To determine the outcomes of percutaneous transluminal angioplastyin the iliac sector, with or without stent placement, the analysis being stratified according to the TASC-2000 typesof lesion. We also sought to estimate the influence of prognostic factors on patency, limb salvage and survival. Patientsand methods. We conducted a retrospective analysis of 101 interventions in 91 patients (85/6 males/females), whosemean age was 61.54 ± 11.59 years. Risk factors: diabetes, 41.6%; hypertension, 41.6%; smoking, 56.4%; ischaemicheart disease, 19.8%; renal failure, 9.9%. The indication was critical ischaemia in 35.7% and limiting claudication in61.4%. TASC A-type lesion: 44.6%, B: 42.6%, C: 10.9%, D: 1.98%. Technique: angioplasty, 35.65% and stent, 64.35%.All the variables, methods of clinical and haemodynamic evaluation, were defined according to SVS/ISCVS criteria.Results. At 66 months, the primary patency rates were 69.84%, secondary rates were 80.64%, limb salvage was 81.5%and survival was 93.6%. Early results: there were 4 technical failures, morphological success was 92.1% and clinicalsuccess was 85.1%. No deaths or amputations were recorded. At 66 months, and stratifying according to the TASC, theprimary morphological and clinical patencies were, respectively: A: 75.09%, 63.65%; B: 68.07%, 69.66% and thesecondary ones were: A: 89.98%, 73.30%; B: 81.03%, 83.14%. The significant prognostic factor for decreased primarypatency was location in the external iliac, and for limb salvage and survival rates it was renal failure. At the presenttime, thanks to the technological advances being made, the excellent outcomes and the low morbidity and mortalityrates, endoluminal iliac treatment can be the preferred therapeutic alternative for these patients. Conclusions. Endovasculartreatment in the iliac sector is applicable in this type of patients, with selective use of stents; the resultsobtained are similar to those in other series

RESUMO

OBJECTIVES: To evaluate the relationship between C-Reactive Protein (hsCRP), a serum marker of inflammation, and endothelial dysfunction in patients with intermittent claudication. DESIGN, PATIENTS AND METHODS: Cross-sectional study with stratified sampling on dependent variables of age, genre, hypertension, hyperlipidemia, diabetes, smoking status and ankle-brachial index (ABI) to select 156 patients from a target population of 4,100 patients with claudication. We assessed the flow-mediated arterial dilation (FMAD) as a reporter of endothelial function and plasma levels of hsCRP and fibrinogen. RESULTS: Patients with a FMAD<3% (range for the lowest 5% of healthy subjects) had increased levels of plasma hsCRP (6.3 vs 2.3mg/L; p<0.05) and fibrinogen (351vs 302mg/L; p<0.05) in comparison to those with FMAD>3%. There was a negative correlation between hsCRP and FMAD(r=-0.465; p<0.05). CONCLUSION: Impaired endothelial dysfunction is association with increased plasma concentrations of inflammatory markers, and both may have a role in the aetiopathogenesis of peripheral arterial disease.

RESUMO

Objetivo. Analizar los resultados de los 100 primeros procedimientos endovasculares infrainguinales realizados en un servicio de Angiología y Cirugía Vascular. Pacientes y métodos. Análisis retrospectivo de 100 procedimientos endovasculares infrainguinales, 46 angioplastia transluminal percutánea (ATP) simple y 54 ATP más stent, en 96 pacientes (100 extremidades) con 136 lesiones femoropoplíteas. Todas las indicaciones de implantación de stent fueron por resultado incompleto de la ATP simple. La indicación clínica fue: claudicación incapacitante, 19 por ciento; isquemia crítica, 81 por ciento. El sector infrainguinal tratado fue: femoral superficial: 73; poplítea: 63. La longitud lesional fue: 8 cm, en un caso. Analizamos resultados a corto plazo según estándares y en el seguimiento mediante análisis actuarial. Resultados. La permeabilidad de la serie general a 21 meses fue del 61,5 por ciento (59,2 por ciento ATP simple frente a 68,6 por ciento ATPstent). En pacientes con isquemia crítica la permeabilidad a 15 meses fue del 61,1 por ciento (56,7 frente a 69,6 por ciento). La tasa de salvación de extremidad a 21 meses fue del 83 por ciento (82,2 frente a 88,9 por ciento) y supervivencia del 92,7 por ciento (91,9 frente a 94,1 por ciento). En cada comparación las diferencias no fueron significativas. Tampoco hubo diferencias en el análisis de la ATP simple frente a ATP-stent en función de los vasos de salida distal, lesiones complejas (TASC C-D) ni oclusiones. Hubo diferencia significativa en las lesiones más leves (TASC A-B), (65,3 frente a 71,2 por ciento) y en las estenosis (61,9 frente a 85,7 por ciento). Conclusiones. Los procedimientos endovasculares en el sector femoropoplíteo muestran buenos resultados a corto y medio plazo con una tendencia superior para la ATP-stent, aunque esta diferencia sólo es significativa en presencia de estenosis o lesiones del tipo A-B (TASC) (AU)

RESUMO

During a three-year period (1970 to 1973) the Beall mitral prosthesis (103, 104 & 105 series) was used in 97 patients for isolated mitral valve replacement. The early surgical mortality rate within the first 30 days of operation was 11.34%. Among the 86 survivors, 7 developed thromboembolic complications (8.14 per cent), and there were 20 late deaths. Incidence of other complications such as prosthetic malfunction and significant intravascular hemolysis are commented. The 92.42 per cent of the late survivors are in Class I or II of the N.Y.H.A. functional classification.
