Síntomas neurológicos motores de inicio súbito en el síndrome de Leriche / Sudden onset motor neurological symptoms in Leriche's syndrome

Resumen El síndrome de Leriche es una enfermedad poco frecuente, con gran morbilidad y mortalidad, que ocurre debido a oclusión de las ramas principales de la aorta abdominal por debajo de la bifurcación de las arterias renales. Clínicamente, se caracteriza por la tríada de claudicación, impotencia y disminución de los pulsos femorales. El diagnóstico se confirma por ecografía Doppler abdominal o angiografía por tomografía computarizada y el tratamiento se basa en el restablecimiento del flujo por debajo del nivel de la oclusión. Se presenta el caso de un paciente con cuadro clínico atípico de dolor lumbar, paraparesia y livideces de miembros inferiores de inicio súbito, con rápido deterioro de su estado general que requirió intervención endovascular urgente. En esta ocasión, los síntomas neurológicos pueden ser explicados por la reducción del flujo sanguíneo de la arteria espinal magna, que en el 25 % de la población se origina en L1 o por debajo de ella y puede generar isquemia de la médula espinal. La presentación atípica de este reporte lo convierte en un desafío clínico de gran importancia.

Abstract Leriche syndrome is a rare disease with high morbidity and mortality that occurs due to occlusion of the main branches of the abdominal aorta below the bifurcation of the renal arteries. Clinically, it is characterized by the triad of claudication, impotence and decreased femoral pulses. Diagnosis is confirmed by abdominal Doppler ultrasound or computed tomography angiography and treatment is based on restoration of arterial flow below the level of occlusion. We present the case of a patient with an atypical clinical presentation of sudden onset of low back pain, paraparesis and lividity of the lower limbs, with rapid deterioration of his general condition that required urgent endovascular intervention. On this occasion, the neurological symptoms can be explained by reduced blood flow in the magna spinal artery, which in 25% of the population originates at or below L1 and can generate spinal cord ischemia. The atypical presentation of this report makes it a clinical challenge of great importance.

Treatment Strategy for Leriche Syndrome Complicated with Ischemic Heart Disease / 日本心臓血管外科学会雑誌

Leriche syndrome is often complicated with ischemic heart disease (IHD). In such cases, as the internal mammary artery (IMA) supplies blood to the lower-limbs through a collateral network, coronary artery bypass grafting (CABG) using IMA is considered to worsen the lower-limb ischemia and use of intra-aortic balloon pumping prior to lower limb revascularization is not possible. Recent advances in endovascular technology enable us to perform endovascular treatment (EVT) even in Leriche syndrome. In 3 patients diagnosed with Leriche syndrome associated with IHD, tailor-made treatments were performed as one-stage or two-stage surgeries. Various techniques such as percutaneous coronary intervention (PCI), CABG, and open surgical revascularization or EVT of lower limbs were employed. EVT is a less invasive and more attractive alternative to open surgical revascularization, it led to new treatment options in patients with this particular circumstance. Considering the severity of pathophysiology, treatment strategy should be determined on a case-by-case basis.

Angiotomografía en sospecha de enfermedad oclusiva aorto-ilíaca (o síndrome de Leriche) / CT angiography for suspected aortoiliac occlusive disease (or Leriche syndrome) / Angiotomografia por suspeita de doença oclusiva aorto-ilíaca (ou síndrome de Leriche)

Introducción. El síndrome de Leriche fue definido en 1940 por René Leriche como una enfermedad oclusiva aorto-ilíaca. Su importancia radica en que ocupa el segundo lugar en incidencia dentro de las enfermedades oclusivas arteriales, después de la enfermedad de la arteria femoral superficial. Objetivo. Presentar el caso clínico de un paciente con Síndrome de Leriche cuyo diagnóstico trombótico fue confirmado por una angiotomografía computarizada con su respectiva reestructuración en 3D. Adicionalmente, se informa al lector sobre los datos propios de la patología a través de una breve revisión de la literatura. Caso clínico. Paciente masculino con síntomas clínicos agudos de enfermedad oclusiva aorto-ilíaca o síndrome de Leriche en una extremidad. Se realiza el respectivo procesamiento de imagen asistida por computador (reconstrucción tridimensional) que evidencia la patología a pesar de que la ecografía Doppler no determinó trombosis inicial. Discusión. En procesos oclusivos arteriales se emplean técnicas no invasivas como la ecografía y la angiotomografía. Sin embargo, esta última es la técnica por excelencia, sobre todo para procesos trombóticos, pues agiliza la anticoagulación, así como el abordaje terapéutico. Conclusiones. La angiotomografía es una técnica no invasiva con alta sensibilidad y especificidad para detectar estenosis aorto-ilíaca. Se ha convertido en una gran herramienta diagnostica por sus alcances imagenológicos, como la obtención de imágenes iso volumétricas, que permiten evaluar todo el trayecto arterial en los diferentes planos, por medio del uso de medios de contraste, superando en resultados a la ecografía.

Introduction. Leriche syndrome was defined in 1940 by René Leriche as an aortoiliac occlusive disease. Its importance lies in it occupying second place in the incidence of occlusive arterial diseases, after superficial femoral artery disease. Objective. Present the clinical case of a patient with Leriche syndrome whose diagnosis of thrombosis was confirmed by a computed tomography angiography with its respective 3D reconstruction. Additionally, the reader is given information about the pathology through a brief summary of the literature. Clinical case. Male patient with acute clinical symptoms of aortoiliac occlusive disease or Leriche syndrome in one limb. The respective computer-assisted image processing (three-dimensional reconstruction) is carried out, which shows the pathology, despite the Doppler ultrasound not initially establishing thrombosis. Discussion. Non-invasive techniques are used in procedures for occlusive arteries, such as ultrasound and CT angiography. However, the latter is a technique par excellence, above all for thrombosis procedures, as well as the therapeutic approach. Conclusions. CT angiography is a non-invasive technique with high sensitivity and specificity in the detection of aortoiliac stenosis. It has become a great diagnostic tool because of its imagery scope, such as obtaining isovolumic images, which enable the assessment of the entire arterial route in different planes, through the use of contrast media, producing more results than the ultrasound.

Abstract Leriche's syndrome is an occlusive vasculopathy that progressively affects the abdominal aorta and the common iliacs. This paper reports the case of a female patient with various vascular risk factors, which presented a clinical picture compatible with vascular occlusion (claudication). The characteristics of a Leriche's syndrome were confirmed by imaging. The patient finally died. Incidence and prevalence of Leriche's syndrome are unknown, cases in the female gender are the main ones in autoimmune diseases. For the diagnosis, an adequate clinical history is required and confirmed by imaging studies. The treatment is aimed at preventing the progress of the disease. Within the pharmacological management are some vasodilators, antiplatelet agents and statins. Surgical management can be an open or endovascular surgery, the first one offers the greatest benefit, despite the risks involved.

Caso clínico de interés: síndrome de leriche. una manifestación inusual de la enfermedad arterial periférica / Leriche syndrome. an unusual manifestation of peripheral artery disease: a case report

RESUMEN El síndrome de Leriche es una condición causada por la obstrucción de las ramas principales de la aorta abdominal por debajo de la salida de las arterias renales con compromiso de todo el árbol arterial, incluyendo las iliacas y femorales. Se presenta un paciente masculino de 62 años de edad con antecedentes de tabaquismo y que consulta al servicio de urgencias por un cuadro clínico de 3 meses de evolución consistente en dolor de miembros inferior, linfedema que predomina en el miembro inferior izquierdo, además de ausencia de pulsos en miembros inferiores. Al aplicar el test IIEF-5 se obtiene una disfunción eréctil moderada. Es importante resaltar este síndrome y la necesidad de diagnosticarlo tempranamente debido a sus consecuencias catastróficas, haciendo énfasis en identificar e intervenir en los factores de riesgo que conllevan a esta presentación inusual de la enfermedad arterial periférica.

ABSTRACT Leriche syndrome is a condition caused by obstruction of the main branches of the abdominal aorta below the outlet of the renal arteries, with involvement of the entire arterial tree, including the iliac and femoral arteries. . We present a 62-year-old male patient with history of smoking who consults the emergency department with clinical features of a 3-month course consisting in lower limb pain, lymphedema more predominant in the left lower limb, and the absence of pulses in the lower limbs. When applying the IIEF-5 test, moderate erectile dysfunction is found. It`s important to highlight this syndrome and the necessity of an early diagnosis for its consequences can be devastating, also to identify and intervene in risk factors that lead to this unusual presentation of peripheral artery disease.

Endovascular treatment of Leriche syndrome: analysis of curative effect / 介入放射学杂志

Objective To evaluate the curative effect of endovascular treatment for Leriche syndrome.Methods The clinical data of 57 patients with Leriche syndrome,who were admitted to authors' hospital during the period from September 2010 to October 2014,were retrospectively analyzed.The curative effect of percutaneous transluminal angioplasty (PTA) was analyzed.Results Among the 57 patients (65 diseased limbs in total),simple PTA was employed in 2,catheter directed thrombolysis (CDT) with subsequent PTA and stenting in 5,and PTA plus stenting in 50.A total of 97 stents were implanted,the technical success rate was 100％.After the treatment,the ankle brachial index (ABI) increased from preoperative (0.42±0.22) to postoperative (0.83±0.15),the difference between the two data was statistically significant (P＜0.01).Thepatients were followed up for (9.8±2.8) months.The 6-month and 12-month primary patency rates were 95.4％ and 90.7％ respectively,the postoperative secondary patency rate was 96.4％.After the treatment,the symptoms of lower limb ischemia were improved in all patients.During perioperative period,iliac artery rupture due to balloon dilatation occurred in 2 patients,pseudoaneurysm at brachial aaery puncture point in one patient,hematoma at puncture point in 3 patients,cerebral infarction in 2 patients and myocardial infarction in one patient.One patient developed contrast-induced nephropathy and finally died of multiple organ dysfunction syndrome.The perioperative mortality was 1.75％.One patient developed in-stent obstruction in 3 months after two stage treatment,and artificial vascular bypass grafting had to be carried out.Conclusion For the treatment of Leriche syndrome,PTA is safe and reliable,it carries less complications and lower perioperative mortality with satisfactory short-term patency rate.(J Intervent Radiol,2017,26:221-224)

Successful Surgical Treatment for Thoracoabdominal Aortic Aneurysm with Leriche Syndrome

Thoracoabdominal aortic aneurysm accompanied by Leriche syndrome is an extremely rare combination of aortic diseases, the surgical management of which has not been described to date. We report the successful treatment of one such case through open surgical repair of the thoracoabdominal aorta.

Aorto-bilateral External Iliac Artery Bypass Graft in a Patient with Leriche Syndrome and an Ileal Conduit / 日本心臓血管外科学会雑誌

We report a patient with Leriche syndrome who had ileal conduit and a right lower quadrant stoma. A 47-year-old man with a history of bladder cancer had undergone radical total cystectomy with formation of an ileal conduit and right lower quadrant stoma 2 years previously. CT scanning revealed total occlusion of the distal aorta. He experienced right lower leg pain after 30 m of walking. Through a repeat midline laparotomy incision, the abdominal aorta was dissected with a transperitoneal approach. To avoid dissection around the ileal conduit, the retroperitoneum was incised (open) at the right of the ascending colon and at the left of the sigmoid colon. A prosthetic graft (Interguard 14×7 mm) was pulled bilaterally through these incisions, to the external iliac arteries. Abdominal aorto-bilateral external iliac artery bypass grafting was performed and the patient was discharged without complications on the 15th postoperative day.

Right Calf Claudication Revealing Leriche Syndrome Presenting as Right Sciatic Neuropathy

The syndrome of aortoiliac occlusive disease, also known as Leriche syndrome, is characterized by claudication, pain, and diminished femoral pulse. We highlight an unusual case of right sciatic neuropathy caused by Leriche syndrome, which was initially misdiagnosed. A 52-year-old male, with a past medical history of hypertension and bony fusion of the thoracolumbar spine, visited our hospital complaining of right leg pain and claudication, and was initially diagnosed with spinal stenosis. The following electrophysiologic findings showed right sciatic neuropathy; but his symptom was not relieved, despite medications for neuropathy. A computed tomography angiography of the lower extremities revealed the occlusion of the infrarenal abdominal aorta, and bilateral common iliac and right external iliac arteries. All these findings suggested omitted sciatic neuropathy associated with Leriche syndrome, and the patient underwent a bilateral axillo-femoral and femoro-femoral bypass graft.

Complete Revascularization of Juxtarenal Aortic Occlusion by Endovascular Treatment and Adjunctive Anticoagulation / 대한내과학회지

Chronic atherosclerotic occlusion of the abdominal aorta is a rare disease in clinical practice. In this disease, juxtarenal aortic occlusion is defined as the condition extended, adjacent to the renal arteries. The treatment of juxtarenal aortic occlusion is more difficult than a 'simple' abdominal aortic occlusion. Vascular surgery of a juxtarenal aortic occlusion-specifically aortic endarterectomy and bypass grafting-is a challenging procedure that almost invariably requires aortic cross-clamping above the level of the renal arteries, and may be associated with significant morbidity and mortality. With the advent of endovascular treatment, percutaneous transluminal angioplasty and stent implantation have been used increasingly as an alternative to conventional surgery in the management of patients with aortoiliac disease. However, endovascular treatment for juxtarenal aortic occlusion is not common and, also, special attention is needed with regard to possible renal complications. Here, we report the successful revascularization of a case of chronic juxtarenal aortic occlusion with endovascular treatment and adjunctive anticoagulation.

Ten year outcomes after bypass surgery in aortoiliac occlusive disease / 대한외과학회지

PURPOSE: Most outcome studies of bypass surgery are limited to five years of follow-up. However, as human life expectancy has increased, analyses of more long-term outcomes are needed. The aim of this study is to evaluate 10-year outcomes of anatomical bypasses in aortoiliac occlusive disease. METHODS: From 1996 to 2009, 92 patients (82 males and 10 females) underwent aortic anatomical bypasses to treat aortoiliac occlusive disease at Samsung Medical Center. The patients were reviewed retrospectively. Kaplan-Meier survival analyses were performed using PASW ver. 18.0 (IBM Co). RESULTS: A total of 72 patients (78.3%) underwent aorto-femoral bypasses (uni- or bi-femoral), 15 patients (16.3%) underwent aorto-iliac bypasses (uni- or bi-iliac), and 5 patients (5.4%) underwent aorto-iliac and aorto-femoral bypasses. The overall primary patency rates of the 92 patients were 86.2% over 5 years and 77.6% over 10 years. The 10-year limb salvage rate and overall survival rate were 97.7% and 91.7%, respectively. CONCLUSION: The overall patency rates of bypass graft and limb salvage rates decreased as time passed. The analysis of results after bypass surgery to treat arterial occlusive disease will be needed to extend for 10 years of follow-up.

Simultaneous Off-pump Coronary Artery Bypass Grafting and Ascending Aorto-bifemoral Bypass in Leriche Syndrome / 日本心臓血管外科学会雑誌

In the presence of Leriche syndrome, the lower extremities are perfused by collateral flow from internal mammary arteries. If an internal mammary artery graft is used in coronary artery surgery, an acute ischemic limb will develop postoperatively. A 52-year-old man was admitted to our department with bilateral claudication. Multidetector row computed tomography with contrast showed total occlusion of the infrarenal abdominal aorta and rich collateral flow to the lower extremities from internal mammary arteries. Cardiac angiography revealed three-vessel disease. Simultaneous coronary artery bypass grafting and an ascending aorto-bifemoral bypass were performed without cardiopulmonary bypass. Postoperative computed tomography angiography showed that grafts to the coronary and bifemoral arteries were patent. This combined procedure is useful for patients with coronary artery disease and aortoiliac occlusive disease. This procedure without cardiopulmonary bypass has not previously been reported.

Treatment for Ischemic Heart Disease as a Comorbidity of Leriche Syndrome / 日本心臓血管外科学会雑誌

The aim of this study was to clarify the comorbidities of patients with Leriche syndrome and ischemic heart disease. We enrolled 26 patients with Leriche syndrome and who had undergone preoperative coronary angiography were enrolled. The comorbidities of diabetes, hypertension, and coronary artery disease developed in more than half of Leriche patients with Leriche syndrome. Marked coronary artery disease was diagnosed in 14 patients, 7 of whom underwent coronary artery bypass surgery. The Revascularization procedures performed in patients with Leriche syndrome were anatomical aortofemoral bypass in 15 and an extra-anatomical axillofemoral bypass in 9. In 2 cases of extra-anatomical bypass, occlusion developed in the long-term.

Descending Thoracic Aorto-bifemoral Artery Bypass Grafting in a Leriche's Syndrome / 대한흉부외과학회지

Extra-anatomic graft bypass is frequently performed instead of standard infrarenal aorto-iliac reconstruction in patients with Leriche syndrome in whom the thrombus extends to the level of the renal arteries. However, many different surgical options are still being attempted due to the unsatisfying long-term graft patency. We performed a descending thoracic aorto-bifemoral bypass graft with 14 and 14-7-7 mm artificial vessels through a posterolateral thoracotomy, a median laparotomy, and a longitudinal inguinal incision in a 48-year-old male who suffered from claudication with Leriche syndrome. After surgery, the patient recovered well and was discharged. The patient walked well without any symptoms during the 6 month follow-up period in the outpatient department. We have concluded that descending thoracic aorto-bifemoral bypass grafting could be considered as an alternative method for patients with Leriche syndrome in whom standard infrarenal aorto-iliac reconstruction is unsuitable.

A Case of Leriche Syndrome Manifested by Anuria / 대한신장학회잡지

Leriche syndrome is an aortoiliac occlusive disease. The aortoiliac junction is the most common sites of chronic obliterative atherosclerosis. Leriche syndrome has a variety of clinical symptoms attributed to the obstruction of the infrarenal aorta. Common clinical symptoms include thigh, hip, and buttock claudication as well as erectile impotence, usually in association with diminished femoral pulses. But acute anuric renal failure as first manifestation of Leriche syndrome is very uncommon. Contrast-enhanced 3D MRA appears to be well suited for assessment of patients with suspected Leriche syndrome. We report a 75-year-old man who presents anuria as first manifestation of Leriche syndrome.

Simultaneous Revascularization for Coronary Artery Stenosis and Peripheral Vascular Disease / 대한흉부외과학회지

There was no significant difference in morbidity and mortality between those that received simultaneous operation for coronary artery disease and peripheral vascular disease versus those that received coronary artery bypass graft alone. Simultaneous operation is also cost effective. A 46 year-old patient with resting chest pain and intermittent claudication was diagnosed as unstable angina and Leriche's syndrome. We performed simultaneous revascularization for coronary artery stenosis with internal mammary artery and right gastroepiploic artery and a bifurcated vascular graft interposition between in the aorta, left common iliac and right femoral arteries for Leriche's syndrome. The postoperative coronary angiogram and aortogram revealed a good patency of the arterial conduits and vascular graft. He has been followed for 12 months without any problem.

Diagnosis and treatment of Leriche syndrome: a report of 33 cases / 中国普通外科杂志

Objective To summarize the diagnosis and treatment of 33 cases of Leriche syndrome. Methods A retrospective review of the clinical data of 33 cases of Leriche syndrome was done. Results Claudication and impotence occurred in 79.9% and 70.4% of the cases. Color Doppler ultrasonography, especially combining with CTA or MRA, was helpful for the diagnosis. Aortic angiography or DSA was necessary for the determination of the clinical patterns and selecting the therapeutic methods. Surgical patterns selestion should be considering the patients' general status and conditions of the affected vessels. Surgical treatment was performed on 25 cases, including12 aortoiliac artery bypasses , 6 aortobifemoral artery bypasses , 4 axillo bifemoral artery bypasses, 2 embolectomies by Fogarty tube only and 1 aortal interposition with artificial vessel plus renal artery plasty. Aorta iliac artery bypasses get the best results with 1 year patency rate(100%) in all cases, and 5 year patency rate of 75.0%, which was significantly superior to those axillo bifemoral artery bypass grafts with 5 year patency rate of 37.5%. All the other 8 patients without operation died within 5 months. Conclusions Early diagnosis and comprehensive therapy should be adopted to improve the long term patency rates of grafts transplantation in Leriche syndrome.
