ABSTRACT

ABSTRACT Purpose: Renal artery pseudoaneurysms (RAPs) and arteriovenous fistulas (AVFs) are rare but potentially life-threatening complications after partial nephrectomy (PN). Selective arterial embolization (SAE) is an effective method for controlling RAPs/AVFs. We assessed the clinical factors affecting the occurrence of RAPs/AVFs after PN and the effects of SAE on postsurgical renal function. Materials and Methods: Four hundred ninety-three patients who underwent PN were retrospectively reviewed. They were placed in either the SAE or the non-SAE group. The effects of clinical factors, including R.E.N.A.L. scores, on the occurrence of RAPs/AVFs were analyzed. The influence of SAE on the estimated glomerular filtration rate (eGFR) during the first postoperative year was evaluated. Results: Thirty-three (6.7%) patients experienced RAPs/AVFs within 8 days of the median interval between PN and SAE. The SAE group had significantly higher R.E.N.A.L. scores, higher N component scores, and higher L component scores (all, p <0.05). In the multivariate analysis, higher N component scores were associated with the occurrence of RAPs/AVFs (Odds ratio: 1.96, p=0.039). In the SAE group, the mean 3-day postembolization eGFR was significantly lower than the mean 3-day postoperative eGFR (p <0.01). This difference in the eGFRs was still present 1 year later. Conclusions: Renal tumors located near the renal sinus and collecting system were associated with a higher risk for RAPs/AVFs after PN. Although SAE was an effective method for controlling symptomatic RAPs/AVFs after PN, a procedure-related impairment of renal function after SAE could occur and still be present at the end of the first postoperative year.

ABSTRACT

El pseudoaneurisma se define como un hematoma pulsátil repermeabilizado, encapsulado y en comunicación con la luz de un vaso dañado. Se origina cuando hay una disrupción de la pared arterial. La hemoptisis es un signo/síntoma de presentación muy rara de aneurisma aórtico torácico y de pseudoaneurisma aórtico torácico. Hay poca información sobre la hemoptisis asociada con la ruptura del aneurisma aórtico cuyo mecanismo no se explica por la presencia de una fístula aortopulmonar. Entre las hipótesis para explicar este fenómeno, se encuentra la capacidad de las arterias bronquiales de volverse hiperplásicas y tortuosas en presencia de una lesión que modifica la arquitectura pulmonar, siendo más susceptibles a la ruptura. También hay descripciones de lesiones directas del parénquima pulmonar por aneurisma roto. El presente caso nos ilustra que debemos considerar a la hemoptisis como signo de alarma en el diagnóstico diferencial de los aneurismas y pseudoaneurismas aórticos entre otras causas que puede ser fatal en breve tiempo por una hemorragia masiva.


Pseudoaneurysm is defined as a reperfused pulsatile hematoma, encapsulated and communicated with the damaged vessel's lumen. It originates when there is a disruption of the arterial wall. Hemoptysis is a very rare sign/symptom of a thoracic aortic aneurysm or pseudoaneurysm. There is little information on hemoptysis associated with aortic aneurysm rupture, whose mechanisms are not explained by the presence of an aortopulmonary fistula. Among the hypotheses to explain this phenomenon, is the ability of the bronchial arteries to become hyperplasic and tortuous in the presence of a lesion that modifies the pulmonary architecture, being more susceptible to rupture. There are also descriptions of direct lung parenchymal injury from ruptured aneurysm. The present case illustrates that we must consider the hemoptysis as a warning sign in differential diagnosis of aortic aneurysms and pseudo aneurysms, among other causes, that it can be fatal in a short time due to massive hemorrhage.

ABSTRACT

Neurofibromatosis is a disease caused by a mutation on chromosome 17, and was described by Friedrich Daniel von Recklinghausen in 1882. It is characterized by the appearance of benign tumors in different organs that can occasionally turn malignant. Four types of neurofibromatosis are described; being type 1 the most frequent, produced by mutations in NF1 gene inhibiting neurofibromin, and in a small percentage of cases by 17q11 microdeletion. In 50% of cases, it is autosomal dominant and the penetrance is 100%. Its prevalence is 1/3000 births and affects both sexes equally. The diagnosis is done by the presence of characteristic signs and can be corroborated through genetic studies. It usually manifests in childhood and involves skin issues, formation of multiple neurofibromas, gliomas of the optic pathway, hamartomas of the iris, bone malformations, arterial hypertension, vascular alterations, intracranial and peripheral nerve sheath tumors, seizures, hydrocephalus, cognitive deficits and learning difficulties. Vascular disease is a rare complication that is usually asymptomatic and can affect the vessels that go from the proximal aorta to small arterioles, including arterial stenosis, aneurysms and arteriovenous malformations. The prognosis is usually good, with neoplasms and vascular diseases being the cause of early mortality. We present the case of a patient with a diagnosis of neurofibromatosis type 1 who presents a rupture of a pseudoaneurysm dependent on the left temporal artery with a fistula with drainage to the superficial facial vein that resulved favorably by endovascular treatment.


La neurofibromatosis es una enfermedad producida por una mutación en el cromosoma 17; fue descrita por Friedrich Daniel von Recklinghausen en 1882. Se caracteriza por la aparición de tumores benignos en distintos órganos que, ocasionalmente, pueden malignizarse. Se describen cuatro tipos de neurofibromatosis; la más frecuente es la de tipo 1, que se produce por mutaciones en el gen NF1, inhibiendo la neurofibromina, y en un pequeño porcentaje de casos por microdeleción 17q11. En el 50% de los casos es autosómica dominante y la penetrancia es del 100%. Su prevalencia es de 1/3000 nacidos vivos y afecta por igual a ambos sexos. El diagnóstico se efectúa por la presencia de signos característicos y puede corroborarse por medio de estudios genéticos. Suele manifestarse en la infancia y comprometer la piel, con formación de múltiples neurofibromas, gliomas de la vía óptica, hamartomas del iris, malformaciones óseas, hipertensión arterial, alteraciones vasculares, tumores intracraneales y de las vainas de nervios periféricos, convulsiones, hidrocefalia, déficit cognitivo y dificultades del aprendizaje. La enfermedad vascular es una complicación rara que suele ser asintomática, puede afectar los vasos que van desde la aorta proximal hasta las arteriolas pequeñas, incluyendo estenosis arteriales, aneurismas y malformaciones arteriovenosas. El pronóstico suele ser bueno; las causas de mortalidad temprana son las neoplasias y las vasculopatías. Presentamos el caso de un paciente con diagnóstico de neurofibromatosis tipo 1 que presentó ruptura de seudoaneurisma dependiente de la arteria temporal izquierda, con fístula con drenaje a la vena facial superficial, que se resolvió favorablemente mediante tratamiento endovascular

ABSTRACT

El pseudoaneurisma arterial es la dilatación de un vaso, producto de la lesión de la pared. Es generado, principalmente, por traumatismos y, en menor medida, por patologías inflamatorias del endotelio. Se presenta como un hematoma pulsátil y doloroso. Su diagnóstico suele realizarse debido a que, ante una ecografía Doppler, se observa una imagen hipoecoica adyacente a un vaso con flujo en su interior. Su baja prevalencia, asociada a su presentación clínica variable, puede generar confusión con infecciones de piel y partes blandas o trombosis. El manejo puede ser desde la compresión extrínseca hasta la cirugía abierta, y no existen algoritmos terapéuticos en la actualidad. Se describeel caso de un paciente de 13 años con un pseudoaneurisma en una rama muscular de la arteria femoral superficial, secundario a un traumatismo cortante en el que se realizó exitosamente el abordaje endovascular con colocación de microcoils para la exclusión del saco pseudoaneurismático.


Pseudoaneurysm or 'false aneurysm' is defined as an abnormal arterial dilatation produced by an injury to its wall that does not affect the three parietal layers like in 'true' aneurysms. In general, false aneurysms are related to traumatisms and, less frequently, to inflammatory disease of vascular endothelium. Clinically, it shows a pulsatile, painful hematoma in the affected region. The initial diagnosis is usually achieved by Doppler ultrasound showing a hypoechoic image in relation to a blood vessel or its wall. Due to the low prevalence of false aneurysm, it is commonly confused with skin and soft tissue's infections or with thrombosis. There are different options of treatment, from extrinsic compression to open surgery. We describe the case of a 13-year-old patient with traumatic false aneurysm of a muscular branch of femoral artery, successfully managed with endovascular exclusion of the lesion with microcoil

ABSTRACT

Abstract Objective: In our clinic, we aimed to investigate the effect of preoperative risk factors and postoperative complications on reoperation and mortality in cases with Behçet's disease which presents very rare coronary artery involvement. Methods: Thirteen patients with Behçet's Disease who had undergone coronary artery bypass grafting in our center between 2003 and 2015 were analyzed. We evaluated the clinical and laboratory findings, complications and mortality rates of our patients in light of the literature. Results: The mean age was 38.5 (30-55; 3 women). The mean time from onset of Behçet's disease to coronary artery disease was 4,7 (3-11) years. Fifty-four percent of the patients were asymptomatic. Coronary artery disease of these was exposed while peripheral vascular surgery was planned due to complications of Behçet's disease. Symptomatic patients presented angina pectoris (31%), acute coronary syndrome (8%) and arrhythmia (8%). In coronary pathology of patients, distal type obstruction (31%), aneurysm and pseudoaneurysm (31%), proximal segment thrombus (15%), chronic type stenosis and occlusions (31%) were present. Early mortality (15%) was due to acute myocardial infarction while the late mortality (15%) was due to cerebral and gastrointestinal bleeding. Reoperation was due to bleeding in one case on the 1st postoperative day and due to acute pulmonary embolism in another case in the 3rdpostoperative year. Conclusion: In Behçet's disease, coronary artery bypass grafting is a procedure with high mortality, especially in the acute period. The on-pump surgery technique in these cases can be safely performed for multiple bypasses and in patients above 40 years old.

ABSTRACT

Introducción: Los aneurismas arteriales son poco frecuentes en edad pediátrica, sin embargo; se observa un incremento en la incidencia de pseudoaneurismas a partir de traumatismos vasculares, sobre todo, por la aplicación de procederes invasivos. También se observan en procesos infecciosos y tumorales adyacentes, que acaban por lesionar la pared arterial. La mayoría suelen ser asintomáticos, o se presentan como una masa pulsátil que se asientan sobre la zona de la arteria afectada. Objetivo: Demostrar la importancia del diagnóstico temprano de los pseudoaneurismas para el tratamiento quirúrgico oportuno y evitar complicaciones posteriores. Presentación del caso: se discute un caso de una paciente de dos años de edad con un trauma vascular iatrogénico en la extremidad inferior derecha, que se manifestó como una tumoración pulsátil. Se realizó eco-doppler y angiografía, con lo que se diagnosticó un aneurisma de la arteria femoral derecha. Se realizó una exéresis y reconstrucción vascular con buena evolución. Conclusiones: El diagnóstico rápido de estas entidades vasculares evita que se presenten complicaciones posteriores y aseguran una evolución rápida y satisfactoria de los pacientes que las padecen(AU)


Introduction: Arterial aneurysms are rare in the pediatric ages. However, it is observed an increasement of the incidence of pseudoaneurysms caused by vascular traumas, mainly due to the use of invasive procedures. It is also present in infectious and tumour processes that end up injuring the arterial wall. Most of them are asymptomatic or are presented as a pulsatile mass that sets up over the affected artery's zone. Objective: To show the importance of early diagnosis of pseudo-aneurysms. Case presentation: It is presented the case of a two years old patient with a iatrogenic vascular trauma in the right lower limb that manifested in the way of a pulsatile tumor. Through an eco-Doppler and an angiography, an aneurysm of the right femoral artery was diagnosed, which led to an excision and a vascular reconstruction with good evolution. Conclusions: Early diagnosis of these vascular entities allows its timely surgical treatment, avoids the appearance of further complications and assures a prompt and satisfactorily evolution of the patients(AU)

ABSTRACT

Resumen Los aneurismas pediátricos son raros y pueden se causados por infección al dañar la pared arterial formando una saculación ciega contigua a su lumen denominada pseudoaneurisma micótico. La mayoría de los casos reportados son de pacientes ancianos con comorbilidades y los agentes causantes más frecuentes son Staphylococcus spp, Salmonella spp, Streptococcus spp y raramente hongos. Se presenta el caso de un niño de 3 años con: diagnóstico reciente de leucemia linfoblástica aguda de precursores B en remisión; alto riesgo de recaída por tratamiento incompleto y antecedente de bacteremia por Staphylococcus epidermidis y fungemia por Cándida tropicalis; vegetaciones cardiacas que hacen embolismo a hígado, bazo, pulmón y cerebro, y pseudoaneurisma micótico parcialmente trombosado de la arteria ilíaca común y externa. El diagnóstico temprano de esta entidad es de vital importancia por el riesgo de ruptura y el manejo quirúrgico dependerá de la localización, el tamaño y las complicaciones asociadas.


Abstract Pediatric aneurysms are rare and can be caused for damaging of the arterial wall secondary to an infection, forming a blind sacculation contiguous to its lumen called mycotic pseudoaneurysm. The majority of reported cases are from elderly patients with comorbidities. The most frequent involucre microorganisms are Staphylococcus spp, Salmonella spp, Streptococcus spp and rarely fungi. We present the case of a 3-year-old boy, with a recent diagnosis of acute lymphoblastic leukemia of B precursors in remission, with a high risk of relapse due to incomplete treatment and a history of bacteremia due to Staphylococcus epidermidis and fungemia due to Candida tropicalis; with cardiac vegetations that produce liver, spleen, lung and brain embolism, in whom a partially thrombosed mycotic pseudoaneurysm of the common and external iliac artery is found. The early diagnosis of this entity is of vital importance because of the risk of rupture. Surgical management will depend on the location, size and associated complications.

ABSTRACT

RESUMEN El pseudoaneurisma de aorta ascendente, como complicación en cirugía cardíaca, tiene una incidencia menor del 0,5%, pero una mortalidad que varía del 6,7 al 60%. La manipulación aórtica y la infección son los principales factores predisponentes. Su clínica puede ser variada y constituir un hallazgo casual en controles posteriores. Se presenta el caso de una paciente operada de cirugía valvular mitral que a los 11 meses del postoperatorio se le diagnostica un pseudoaneurisma de aorta ascendente, que requirió tratamiento quirúrgico de emergencia. La cirugía fue llevada a cabo con la utilización de canulación periférica extramediastínica, sin requerir parada circulatoria, ni hipotermia para su correcta disección. El caso muestra una variante técnica para enfrentar una enfermedad poco frecuente, pero altamente desafiante, por la necesidad de reintervención y una correcta estrategia quirúrgica.


ABSTRACT False ascending aortic aneurysm, as a complication in cardiac surgery, has an incidence of less than 0.5%, but a mortality that ranges from 6.7% to 60%. Aortic manipulation and infection are the main predisposing factors. Its clinical presentation is non-specific and may be found incidentally on subsequent check-ups. The case of a patient undergoing mitral valve surgery who was diagnosed with ascending aortic false aneurysm, eleven months after postoperative period, requiring emergency surgical treatment is presented. The surgery was performed using extra-mediastinal peripheral cannulation, without induced circulatory arrest or hypothermia for proper dissection. The case shows a technical version to face an uncommon but highly challenging disease as it needs re-interventions and successful surgical strategies.

ABSTRACT

INTRODUÇÃO: Pseudoaneurismas são geralmente resultantes de trauma sem corte levando provocando a laceração de parte da parede do vaso promovendo o extravasamento de sangue para os tecidos circundantes, seguidos por tamponamento e formação do coágulo. OBJETIVO: Apresentar um caso de pseudoaneurisma em artéria carótida externa como complicação de fratura de côndilo mandibular. RELATO DE CASO: Paciente de 18 anos de idade, vítima de acidente motociclístico compareceu à emergência do Hospital Regional do Cariri com fratura de côndilo mandibular associada à fratura de coronoide e parassínfise, evoluindo com pseudoaneurisma de artéria carótida externa e submetido à embolização seletiva. CONCLUSÃO: Ressaltamos que pseudoaneurismas da artéria carótida externa apresentam as fraturas de côndilo mandibular como fatores etiológicos raros, no entanto uma cuidadosa análise das suas características anatômicas assim como o diagnóstico precoce concorrem para a prevenção de acidentes e complicações graves nas abordagens dos traumas de face...

Introduction: Pseudoaneurysms are usually the result of blunt trauma leading to laceration of part of the vessel wall promoting extravasation of blood into surrounding tissues followed by tamponade and clot formation. Purpose: To present a case of external carotid artery pseudoaneurysm as a complication of mandibular condyle fracture. Case report: An 18-year-old patient, a motorcycle accident victim, attended the emergency of the Cariri Regional Hospital with a mandibular condyle fracture associated with a coronoid fracture and a parasymphysis, evolving with external carotid artery pseudoaneurysm and submitted to selective embolization. Conclusion: We emphasize that pseudoaneurysms of the external carotid artery present mandibular condyle fractures as rare etiological factors, however a careful analysis of their anatomical characteristics as well as early diagnosis contributes to the prevention of accidents and serious complications in the face trauma approaches...

ABSTRACT

Vascular Ehlers-Danlos Syndrome (VEDS) is a rare autosomal dominant disorder caused by mutations in the COL3A1 or COL1A1 genes. Its mortality is secondary to sudden and spontaneous rupture of arteries or hollow organs. The genotype influences the distribution of arterial pathology with aneurysms of intra-abdominal visceral arteries being relatively uncommon. We describe the case of a young man with probable VEDS who died of a spontaneous rupture and dissection of the cystic artery. The patient initially presented with abdominal pain due to an unrecognized spontaneous perforation of the small intestine complicated by sepsis. We postulate that inflammatory mediators may have triggered the arterial rupture due to remodeling and weakening of vessel walls. The phenotype of the patient's vascular damage included bilateral spontaneous carotid-cavernous sinus fistulae and dissection with pseudoaneurysm formation of large- and medium-sized arteries, predominantly the abdominal aorta and its branches. The autopsy uncovered a long history of vascular events that may have been asymptomatic. These findings along with a positive family history supported the VEDS diagnosis. Loeys-Dietz, Marfan, and familial thoracic aortic aneurysm and dissection syndromes were ruled out based on the absence of arterial tortuosity, eye abnormalities, bone overgrowth, and the distribution of vascular damage among other features. Interestingly, microscopic examination of the hippocampus revealed a focus of neuronal heterotopia, commonly associated with epilepsy; however, the patient had no history of seizures. The natural course of VEDS involves the rupture and dissection of arteries that, if unrecognized, can lead to a rapid death after bleeding into free spaces.

ABSTRACT

ABSTRACT Minimally invasive procedure for hemorrhoids is one of the commonest new wave operations done for prolapsed hemorrhoids. The diameter of the stapled tissue is critical in this operation, and an increase in the same could include more tissue in the anvil, with disastrous results. This is a case report of a post minimally invasive procedure for hemorrhoids bleed, which was refractory to two local oversewing attempts. When the bleeding was massive, an angiogram was obtained. This revealed a pseudo aneurysm of the left superior haemorrhoidal artery, which was embolized, stopping the bleed. The stapler dimensions were studied and the possible cause of the event was arrived at. The specific stapler used had a diameter of 2 mm more than the regular Medtronic and Ethicon staplers, possibly including more of the rectal wall, and the superior haemorrhoidal artery as well. This case report documents a rare and potentially fatal complication of a simple procedure.


RESUMO O procedimento minimamente invasivo para as hemorroidas (PMIH) é uma das novas operações mais comuns para ao tratamento de hemorroidas prolapsadas. O diâmetro do tecido grampeado é crítico nessa operação; um aumento nesse diâmetro poderia colocar mais tecido na bigorna do grampeador, com resultados desastrosos. Este relato de caso descreve o desfecho de uma hemorragia após PMIH, refratária a duas tentativas locais de sobressutura. Um angiograma foi realizado quando a hemorragia foi considerada intensa. O exame revelou um pseudoaneurisma da artéria hemorroidária superior esquerda, que foi embolizada, interrompendo o sangramento. As dimensões do grampeador foram estudadas e descobriu-se a possível causa do evento. O grampeador específico usado tinha um diâmetro 2 mm maior do que os grampeadores regulares da Medtronic e da Ethicon e possivelmente captou uma área maior da parede retal e a artéria hemorroidária superior. Este relato de caso documenta uma complicação rara e potencialmente fatal de um procedimento simples.

ABSTRACT

SUMMARY Hemorrhagic pseudocysts with pseudoaneurysms are a rare and fatal complication of chronic pancreatitis due to the erosion of pancreatic to peripancreatic arteries. The timing of the rupture cannot be accurately predicted, but prompt diagnosis and management are essential to prevent further bleeding. We describe the case of a 68-year-old man who presented acute epigastric pain and anemia and had a history of chronic pancreatitis with a pseudocyst. A biliary and pancreas MRI showed an enlarged size of a known pancreatic pseudocyst with internal high signal intensity material. Color-Doppler ultrasonography showed pulsating signals in the pseudocyst, and our final diagnosis was a pseudoaneurysm in the pancreatic hemorrhagic pseudocyst. The pseudoaneurysm was successfully treated with coil embolization of the feeding artery. We report this case of a rare complication of chronic pancreatitis to show that color-Doppler ultrasound is a non-invasive and effective diagnostic tool for pseudoaneurysm, which enables early detection and prompt treatment without the need for invasive diagnostic modalities.
