    Reparación endovascular de Aneurisma aórtico abdominal: Estudio piloto de endoprótesis Ovation™. Resultados comparativos
    (2011) Valdés, F.; Mertens, R.; Bergoeing Reid, Michel Paul; Mariné M., Leopoldo; Krämer, A.; Vargas, F.; Lema F., Guillermo; Canessa, Roberto; Vergara, J.
    Introducción: Las endoprótesis actuales para tratar aneurismas aórticos (AAA) requieren introductores de alto diámetro (18-25F) y se sustentan excluyendo el aneurisma, mediante la fuerza radial de stents metálicos. Objetivo: prótesis Ovation™ (TriVascular, EEUU) con aquellas disponibles en el mercado. Material y Método: Entre Noviembre 2009 y Agosto 2010 tratamos 47 AAA. En 10 pacientes usamos Ovation™ (Grupo 1). Grupo Control (2): diez pacientes tratados contemporáneamente con endoprótesis comerciales. Ovation™ es tri-modular, de PTFE y nitinol con un stent barbado para fijación supra-renal. Sella bajo las arterias renales mediante 2 anillos llenados con un polímero durante el implante. Usa introductor 13-15F. Usa-Philips-Allura (Best, Holanda). Comparamos: duración del procedimiento, hospitalización y complicaciones. Utilizamos test de Fisher exacto y t de student no pareado. Resultados: Éxito técnico 100%. Sin diferencia entre grupos (edad, sexo, tamaño AAA, riesgo ASA, laboratorio preoperatorio). Tiempo operatorio (hrs): 2,12 ± 0,7 vs. 2,0 ± 0,6 (NS). Estadía postoperatoria (hrs): 44,5 ± 10,7 vs 49,5 ± 32,0 (NS). El cuello del AAA y la permanencia en UTI fueron más cortos en grupo 1 (p= 0,035 y 0,0451). Seguimiento (4,5-12 meses) sin eventos adversos, endofugas tipo I ni III, ni re-intervenciones. Conclusiones: Los resultados con Ovation™ a corto plazo son comparables con los de otras endoprótesis, cumpliendo con estándares de eficacia y seguridad. Ovation ™ navega por vasos pequeños, permite un despliegue preciso y sellado efectivo en cuellos > 7 mm, ampliando el tratamiento endovascular del AAA.

    Telemedicina en cirugía vascular y endovascular: experiencia en un centro universitario
    (2022) Morales Palma, Álvaro José; Torrealba Fonck, José Ignacio; Bergoeing Reid, Michel Paul; Mariné M., Leopoldo; Mertens Martin, Renato; Valdés Echeñique, José Francisco; Vargas Serrano, José Francisco
    Background: Telemedicine became a relevant means to provide healthcare without face-to-face medical evaluation during the COVID-19 pandemic. Aim: To describe the effectiveness of telemedicine in vascular surgery. Materials and Methods: Review of medical records of all vascular surgery consultations carried out in a clinical hospital between April and October 2020. The main outcome measured was the resolution of the reason for consultation. Secondary outcomes were the need to request laboratory tests or imaging, the need to evaluate the patient in person, and the need for referral to hospitalization or emergency service. Results: One hundred-six new consultations and their follow-up (remotely or in person) were analyzed. A definitive diagnosis could be reached in 74% of consultations, treatment could be instituted or modified in 69% of them, and the reason for consultation could be resolved in 74% of cases. Laboratory and imaging tests were requested in 36 and 63% of consultations, respectively. Four percent of patients were referred to the emergency department or hospitalization. Conclusions: In the vast majority of consultations, it was possible to achieve a definitive diagnosis, prescribe a treatment and resolve the reason for consultation without the need for a face-to-face medical evaluation.

    Three Cases of Intracardiac Leiomyomatosis with Very Long-term Follow-up
    (Korean Society for Vascular Surgery, 2024) González Urquijo, Mauricio; Valdés E., Francisco; Mertens Martin, Renato; Mariné M., Leopoldo; Vargas Serrano, José Francisco; Bergoeing Reid, Michel Paul
    Uterine intravascular leiomyomatosis (IVL) with extension into the right heart is uncommon, with no more than 400 cases reported in the literature since 1907. The present study aims to report three patients with intracardiac IVL surgically treated in our institution, with long-term follow-up. Three female patients in their third to fifth decades of life, with a history of difficult hysterectomy due to extensive myomatosis, presented with symptoms of right-sided heart failure. Echocardiography and computed tomography were performed, where IVL extending from the pelvis into the right heart was observed. All three patients underwent a one-stage operation under extracorporeal circulation through a right auriculotomy and inferior vena cavotomy, accessed via a sterno-laparotomy. The tumors were extirpated without complications, with ligation of the vena cava or iliac vein. The patients at 10-, 13-, and 37-year follow-up were well and alive with mild lower extremities symptoms.

    Tratamiento endovascular de la disección aórtica tipo B mediante endoprótesis
    (2008) Mertens Martin, Renato; Arriagada Jorquera, Ivette Andrea; Valdés Echeñique, José Francisco; Kramer, Albrecht; Mariné M., Leopoldo; Bergoeing Reid, Michel Paul; Braun Jones, Sandra; Godoy Jorquera, Iván Esteban; Córdova Alvestegui, Samuel Edmundo; Huete Garín, Álvaro; Vergara G., Jeannette; Carvajal Núñez, Claudia
    Background: Dissections that involve the ascending aorta are classified as type A, regardless of the site of the primary intimal tear, and all other dissections as type B. Type B dissections can have fatal ischemic and hemorrhagic complications. In the chronic state, dilatation and rupture can be mortal. Endovascular surgery is a therapeutic alternative, considering the high rate of complications of conventional surgery. Aim: To report the results of endovascular treatment of type B aortic dissection. Material and methods: Report of 36 treated patients (30 males) aged 43 to 87 years, with a type B aortic dissection. Seventy eight percent were hypertensive and 39% smoked. The diagnosis was confirmed by CAT scan. Acute patients were treated for complications and chronic patients, for dilatation. In the operating room, an endoprothesis was placed through the femoral artery, to cover the tear. The tear was located and the lumens were differentiated using angiography and transesophageal echocardiography. Results: All procedures were successful. In 16 acute dissections the indications were malperfusion syndrome or unmanageable hypertension in seven patients and imminent rupture or persistent pain in nine. Twenty chronic patients were operated due to dilatation (mean 6 cm). One patient died due to cardiac failure. One patient had a transient paraparesia and two had pulmonary embolism. No patient died in a follow up period ranging from 2.5 to 74 months. Four patients required a new aortic endovascular procedure due to progressive dilatation or endoleak. Conclusion: Endovascular treatment of type B aortic dissection has good immediate and long term results (Rev Méd Chile 2008; 136: 1431-8).

    Uso de endoprótesis bifurcada ilíaca para revascularización hipogástrica durante tratamiento de aneurisma aorto-ilíaco
    (2010) Mertens Martin, Renato; Kramer, Albrecht; Valdés Echeñique, José Francisco; Mariné M., Leopoldo; Bergoeing Reid, Michel Paul
    Una anatomía desfavorable es un obstáculo a vencer con el tratamiento endovascular del aneurisma aorto-ilíaco. La presencia de aneurisma ilíaco bilateral es frecuente y amenaza la adecuada fijación distal de una endoprótesis. Esta condición puede ser manejada: a) aumentando el diámetro del dispositivo a nivel ilíaco, con limitaciones en las medidas disponibles; b) embolización hipogástrica bilateral, aceptando una morbimortalidad mayor; c) combinando un abordaje quirúrgico retroperitoneal para revascularizar una arteria hipogástrica, aumentando el impacto del procedimiento; d) mediante revascularización retrógrada unilateral desde la arteria ilíaca externa ipsilateral con otra endoprótesis. Recientemente se ha descrito el uso de endoprótesis ramificadas, que requieren un despliegue complejo, pero permiten revascularizar una o ambas arterias hipogástricas en forma anterógrada y estable. Reportamos el caso de un paciente de sexo masculino y 57 años, de alto riesgo para cirugía convencional, portador de un aneurisma pequeño de aorta abdominal y aneurismas ilíaco común bilateral e hipogástrico izquierdo. Fue tratado mediante despliegue de una endoprótesis bifurcada ilíaca, revascularizando la arteria hipogástrica derecha y embolizando la izquierda aneurismática, asociado a implante de una endoprótesis aórtica convencional, también bifurcada. El paciente evoluciona sin complicaciones, con claudicación glútea izquierda leve en disminución y preservación de su función sexual. Una tomografía axial computada demuestra exclusión efectiva de sus aneurismas. Esta nueva técnica permite tratar de manera segura a pacientes portadores de aneurisma ilíaco bilateral en forma endo-vascular, manteniendo perfusión de la circulación pelviana y disminuyendo el impacto de un procedimiento convencional en pacientes de alto riesgo.
