    (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.

    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).

    Tratamiento endovascular del trauma de aorta descendente
    (2005) Mertens Martin, Renato; Valdés Echeñique, José Francisco; Kramer, Albrecht; Bergoeing Reid, Michel Paul; Zalaquett Sepúlveda, Ricardo; Baeza Prieto, Cristian Rafael; Moran Velásquez, Sergio; Irarrázaval Llona, Manuel José; Becker Rencoret, Pedro Antonio; Huete Garín, Álvaro; Vergara G., Jeannette; Valdebenito G., Magaly
    Background: Mortality of traumatic aortic lesions is over 80%. A group of those who survive, develop a chronic pseudo aneurism, usually asymptomatic, that is detected during imaging studies. Since conventional surgical treatment of traumatic aortic lesions has a great mortality, endovascular treatment has been used as an alternative treatment in the last decade. Aim: To report our experience with endovascular treatment of traumatic aortic lesions. Patients and methods: Report of seven patients aged 22 to 65 years, with traumatic aortic lesions. Under general anesthesia an endovascular prosthesis was inserted through the femoral artery. Results: No complications were observed in the postoperative period, and after a follow up ranging from 4 to 40 months, no endoleaks or other complications have been detected. Conclusions: Endovascular treatment of traumatic aortic lesions has good immediate and midterm results.

    Two cases of complex renal artery aneurysms treated with renal autotransplantation
    (SAGE Publications, 2025) Martin, Ariana Marie; González Urquijo, Mauricio; Castillo Amulef, Francisca Alexandra; Mariné M., Leopoldo; Bergoeing Reid, Michel Paul; Valdés Echeñique, José Francisco; Vargas Serrano, José Francisco
    Objective: To report on the surgical treatment of complex renal artery aneurysms (RAAs) using kidney autotransplantation in two patients at a single institution.Methods: We retrospectively reviewed two cases of patients with RAA treated with renal autotransplantation at a single center over a period of 15 years.Results: Case 1: A 50-year-old male presented to the outpatient clinic with left flank and lumbar pain. A CT scan revealed a 25 mm aneurysm at the left renal pelvis and bilateral renal fibromuscular dysplasia. A laparoscopic left nephrectomy was performed, followed by bench aneurysm resection, saphenous vein bypass reconstruction, and kidney autotransplantation into the right iliac fossa. At 11 years follow-up, his renal function remains normal, with adequate patency and function of the transplanted kidney. Case 2: A 51-year-old male reported a 6-month history of nonspecific abdominal pain. A CT scan revealed nephrolithiasis and multiple renal artery aneurysms, the largest measuring 50.2 mm in his right kidney. He underwent laparoscopic right nephrectomy and renal autotransplantation in the right iliac fossa. At 3 years follow-up, the patient remains asymptomatic with normal renal function.Conclusion: Ex vivo autotransplantation is an acceptable option for addressing complex RAAs beyond the bifurcation of the main renal artery.

    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.
