ABSTRACT

Presentamos el caso de un niño de 12 años que consultó por hemoptisis, sin otros sín- tomas asociados. Se realizó radiografía de tórax (patológica), laboratorio con aumen- to moderado de reactantes de fase aguda, PPD (negativa), esputos x 3 con bacilosco- pias negativas y tomografía de tórax con contraste i.v. que mostró imágenes de árbol en brote en todos los lóbulos y una imagen de dilatación vascular de una rama de la ar- teria pulmonar en lóbulo superior izquierdo. Se plantearon diagnósticos diferenciales: malformación vascular primaria o lesión secundaria a infección. La angiografía digital permitió confirmar el pseudoaneurisma y embolizarlo. Luego de 17 días, 2/3 cultivos de esputo fueron positivos para Mycobacterium tuberculosis. El niño realizó tratamiento antituberculoso con drogas de primera línea con evolución clínica favorable. Este caso resalta la importancia de considerar el pseudoaneurisma de Rasmussen en- tre las posibles complicaciones de un paciente con tuberculosis y hemoptisis recurren- te o masiva.


We present the case of a 12-year-old boy admitted to the hospital due to hemoptysis without other symptoms. We performed a Thorax X-Ray (pathological), laboratory with elevated acute phase reactants, TST (negative), sputum x 3 with negative smear and computed tomography angiography showing a tree-in-bud pattern in all lobes, and di-latation of a brunch of the pulmonary artery in the upper left lobe. We considered pri-mary vascular anomaly or lesion due to infection as a differential diagnosis. The patient underwent digital angiography and therapeutic embolization of this pseudoaneurysm. After seventeen days, 2/3 of the sputum cultures were positive for Mycobacterium tu-berculosis. The patient received standard anti-TB therapy with favorable evolution. This case highlights the importance of considering complications such as Rasmussen's pseudoaneurysm in patients with pulmonary tuberculosis and recurrent or massive hemoptysis.

ABSTRACT

We describe the case of an 82-year-old man who had recently undergone cardiac surgery (quadruple coronary bypass), who consulted due to the appearance of a necrotic eschar on the thumb of the right index finger, together with paraesthesia and hypoaesthesia in the first 3 fingers of the same hand. An ultrasound scan of the right elbow was performed to rule out involvement of the median nerve and an anechoic, thick-walled mass was found, dependent on the wall of the proximal ulnar artery, compatible with a pseudoaneurysm of the same, compressing the nerve. Electromyography showed an acute lesion of the proximal median nerve and angio-CT confirmed the diagnosis of pseudoaneurysm of the proximal ulnar artery. Pseudoaneurysm is a dilatation by rupture of the arterial wall, which does not involve all three layers of the arterial wall and communicates with the vascular lumen. Its development after vascular manipulation is very rare, and it is uncommon for it to act by compressing a nerve structure. In our case, together with vascular surgery, treatment with intralesional thrombin was decided, with good evolution.


Se describe el caso de un varón de 82 arios intervenido recientemente de cirugía cardíaca (cuádruple bypass coronario), que consulta por aparición de una escara necrótica en el pulpejo del dedo índice derecho, junto a parestesias e hipoestesias en los tres primeros dedos de dicha mano. Se realiza una ecografía del codo derecho para descartar afectación del nervio mediano y se objetiva una masa anecoica, de paredes engrosadas, dependientes de la pared de la arteria cubital proximal, compatible con pseudoaneurisma de esta, que comprime dicho nervio. En la electromiografía se evidencia una lesión aguda del nervio mediano a nivel proximal y en el angio-TC se confirma el diagnóstico de pseudoaneurisma de la arteria cubital proximal. El pseudoaneurisma es una dilatación por rotura de la pared arterial, que no implica a las tres capas de esta y se comunica con la luz vascular. Su desarrollo tras una manipulación vascular es muy infrecuente y que actúe comprimiendo una estructura nerviosa es poco común. En nuestro caso, conjuntamente con cirugía vascular se decidió tratamiento con trombina intralesional, con buena evolución.

ABSTRACT

@#Pancreatic pseudoaneurysms are possible complications of chronic pancreatitis. These may present as hemosuccus pancreaticus, a rare cause of upper gastrointestinal tract bleeding where a pseudoaneurysm erodes into an adjacent pseudocyst or pancreatic duct, manifesting as bleeding through the pancreatic duct into the duodenal papilla. We report a case of a 32-year-old male with a history of chronic pancreatitis presenting as intermittent upper gastrointestinal tract bleeding secondary to hemosuccus pancreaticus from a pancreatic pseudoaneurysm. The patient underwent multiple sessions of endovascular embolization, which successfully controlled the bleeding despite some failed attempts; thus, a potentially morbid last-resort surgery was avoided.

ABSTRACT

Pseudoaneurysms of the neck are seldom, and those caused by neck infections especially parapharyngeal abscess are even rarer. However, it is life-threatening and may bring sudden death due to the obstruction of airway and the pseudoaneurysms rupture. We analyzed the clinical features, diagnosis and treatment of the disease through a case summary and literature review in order to guide clinical diagnosis and treatment of pseudoaneurysms. The patient, whom we presented was an 87-year-old male and admitted in emergency of our hospital with the chief complaint of neck swelling for 7 days and shortness of breath for 2 days. Cervical ultrasound examination showed that there was an liquid dark area next to the left common carotid artery which was approximately 8.0 cm × 5.0 cm, consideration of formation of left carotid artery pseudoaneurysm, and the liquid dark area which was visible on the right considered of pseudoaneurysm or infection. Angiography of neck showed a clustered high-density shadow around the bifurcation of the left carotid artery, with an overall range of approximately 65 mm × 52 mm × 72 mm, the pseudoaneurysms for sure, while on the right side of the lesion, mixed low density shadows with air could be seen, the parapharyngeal abscess for sure.Then he was diagnosed as the pseudoaneurysm of left internal carotid artery which was caused by parapharyngeal abscess. After tracheal intubation and anti-infection treatment, the patient died due to hemorrhagic shock of the ruptured of the pseudoaneurysm. Morever we performed literature search on PubMed, Wanfang database and CNKI with keywords of "neck pseudoaneurysm, neck infection, parapharyngeal abscess" and enrolled 10 cases. Then we summarized the clinical characteristics and treatment. We analyzed and summarized the 10 case reports, in which the number of male was 7. Among them, there were 4 pediatric, and 6 adults were enrolled overall. Most of the symptoms were neck swelling, and the diseased blood vessel was mainly the right internal carotid artery which accounted for half overall. All the patients underwent surgical intervention, and recovered well. So we draw the conclusion that the clinical incidence of cervical pseudoaneurysms is low and can be caused by a variety of factors, especially caused by infectious factors. When a patient has a progressive pulsating mass in the neck, the preliminary diagnosis should be made by ultrasound as soon as possible, and the aortic enhancement CT should be used to further confirm.For a patient with cervical pseudo-aneurysms caused by parapharyngeal infections, he should take operation timely combined with antibiotic treatment in time.

ABSTRACT

Introducción: Se presenta un caso clínico de seudoaneurisma de la arteria femoral circunfleja lateral secundario a una fractura pertrocantérica de cadera. Materiales y métodos: Como el cuadro y su localización son infrecuentes, se llevó a cabo una revisión bibliográfica sistematizada que incluyó todos los casos publicados sobre esta enfermedad (n = 40) en los últimos 15 años. Resultados: No se hallaron asociaciones estadísticamente significativas entre ninguna de las variables estudiadas. Sin embargo, parece existir cierto consenso en mantener una alta sospecha clínica para una intervención precoz y así obtener mejores resultados. Tanto su etiología como su localización se relacionan con la morfología de la fractura, el gesto quirúrgico y el material de osteosíntesis. Asimismo, hay una tendencia mayor a utilizar la angiotomografía para el diagnóstico y la localización del seudoaneurisma. Conclusiones: Nuestra paciente es el primer caso de resolución espontánea. Es fundamental conocer esta complicación tan poco frecuente para optimizar los resultados terapéuticos. Esta revisión, la más reciente sobre el tema, es muy útil para enumerar y subrayar los aspectos más importantes sobre el manejo y la prevención de los seudoaneurismas secundarios a una fractura de cadera. Nivel de Evidencia: IV


Introduction: We present a case of a lateral circumflex femoral artery pseudoaneurysm associated with pertrochanteric hip fracture. Materials and methods: We performed a systematic review considering all cases published in the last 15 years about this pathology (n=40). Results: No statistically significant associations were found between any of the variables studied. However, there seems to be some consensus in maintaining a high clinical suspicion for early intervention, thus obtaining better outcomes. Both its etiology and location are related to the morphology of the fracture, the surgical procedure, and the osteosynthesis material. Likewise, there is a greater tendency to use CT angiography for the diagnosis and localization of the pseudoaneurysm. Conclusion: Our patient is the first reported case of spontaneous resolution. Knowing this rare complication is essential to optimize therapeutic results. This review, the most recent on the subject, is very useful in listing and highlighting the most important aspects of the management and prevention of pseudoaneurysms secondary to hip fracture.

ABSTRACT

Resumo A artéria femoral profunda, devido às suas características anatômicas, se encontra protegida da maioria dos traumatismos vasculares. Relatamos um caso de pseudoaneurisma de ramo perfurante da artéria femoral profunda, associado à fístula arteriovenosa, secundário a rotura completa do músculo vasto medial em paciente jogador de futebol. A ressonância magnética demonstrou lesão muscular associada a pseudoaneurisma, e a angiotomografia confirmou a presença de pseudoaneurisma associado a fístula arteriovenosa de ramo da artéria femoral profunda. Foi realizado tratamento endovascular da fístula através da embolização com micromolas fibradas e drenagem cirúrgica do hematoma muscular. O paciente evoluiu bem, sem queixas clínicas no 30º dia de pós-operatório e também após 1 ano.


Abstract Due to its anatomical characteristics, the deep femoral artery is protected from most vascular injuries. We report a case of a soccer player with pseudoaneurysm of a perforating branch of the deep femoral artery, associated with an arteriovenous fistula and secondary to complete rupture of the vastus medialis muscle. Magnetic resonance imaging showed muscle damage associated with a pseudoaneurysm and angiotomography confirmed the presence of a pseudoaneurysm associated with a deep arteriovenous fistula of a branch of the deep femoral artery. Endovascular treatment of the fistula was performed by embolization with fibrous microcoils and surgical drainage of the muscle hematoma. The patient recovered well, was free from clinical complaints on the 30th postoperative day and also after 1 year.

ABSTRACT

Introduction The middle meningeal artery (MMA) is an important artery in neurosurgery. As the largest branch of the maxillary artery, it provides nutrition to the meninges and to the frontal and parietal regions. Diseases, including dural arteriovenous fistula (DAVF), pseudoaneurysm, true aneurysm, traumatic arteriovenous fistula (TAVF), Moya-Moya disease (MMD), recurrent chronic subdural hematoma (CSDH), migraine, and meningioma,may be related to the MMA. The aim of the present study is to describe the anatomy of the MMA and to correlate it with brain diseases. Methods A literature review was performed using the PubMed, Scielo, Scientific Direct, Ebsco, LILACS, TripDataBase and Cochrane databases, with the following descriptors: neurosurgery, neuroanatomy, meninges and blood supply. Discussion The MMA is embedded in a cranial groove, and traumatic or iatrogenic factors can result in MMA-associated pseudoaneurysms or arteriovenous fistulas (AVFs). In hemodynamic stress, true aneurysms can develop. Arteriovenous fistulas, pseudoaneurysms, and true aneurysms can be effectively treated by endovascular or surgical removal. In MMD, the MMA plays a role in the development and in the improvement of collateral circulation. Finally, in cases of CSDH, when standard surgery and drainage fail, MMA embolization can constitute a great alternative. Conclusion The MMA is a relevant structure for the understanding of neurosurgical diseases. In conclusion, every neurosurgeon must know the anatomy of the MMA sufficiently to correlate it with the diagnosed pathology, thus obtaining treatment effectiveness and preventing brain lesion.

ABSTRACT

El aneurisma micótico surge de la destrucción infecciosa de la pared arterial y se diagnostica cuando hay un aneurisma en el contexto de inflamación y hemocultivos o biopsia positivos, aunque esto no es un requisito excluyente. Los agentes etiológicos de mayor frecuencia son bacterias (Staphylococcus, Salmonella)2 pero también se han notificado hongos (Aspergillus niger). La tuberculosis puede afectar cualquier órgano de la economía, el compromiso arterial es una complicación rara y potencialmente mortal, puede ocurrir por extensión directa de un foco adyacente o por diseminación hematógena o linfangítica de lesiones primarias. El compromiso en los grandes vasos puede presentarse de diversas formas, incluyendo pólipos, aortoarteritis estenosante y formación de aneurismas o pseudoaneurismas, siendo esta última la más común. Presentamos el diagnóstico de aneurisma de aorta abdominal infrarrenal con trombo intramural y pseudoaneurisma de aorta renal izquierda como hallazgo incidental en una paciente con tuberculosis ganglionar.


The mycotic aneurysm arises from the infectious destruction of the arterial wall and is diagnosed when there is an aneurysm within the context of inflammation and positive blood cultures or biopsies, though this is not an essential requirement. The most common etiologic agents are bacteria (Staphylococcus, Salmonella)2, but fungi have also been reported (Aspergillus niger). Tuberculosis may affect any organ of the body; arterial compromise is a rare and potentially mortal complication that may occur by direct extension of an adjacent infected site or by bloodstream or lymphangitic dissemination of primary lesions. The great vessels may be compromised in different ways, including polyps, stenotic aortoarteritis and formation of aneurysms or pseudoaneurysms, being the latter the most common one. We present the diagnosis of infrarenal abdominal aortic aneurysm with intramural thrombus and left renal aortic pseudoaneurysm as incidental finding in a patient with nodal tuberculosis.

ABSTRACT

RESUMEN Los pseudoaneurismas de la arteria humeral son infrecuentes, pero pueden asociarse a complicaciones de alta morbilidad como la isquemia de miembro superior. Comunicamos un caso de pseudoaneurisma humeral en el pliegue del codo, que se presentó como tumor pulsátil con leve disminución de la temperatura y parestesias en la mano homolateral de un año de evolución, debido a una punción arterial inadvertida durante la venopunción para extracción de sangre. Se trató con éxito mediante resección quirúrgica más reconstrucción vascular con bypass húmero-cubital y bypass húmero-radial ambos con vena safena. Se discuten las diversas opciones terapéuticas disponibles para los pseudoaneurismas humerales considerando las características anatómicas y la sintomatología del paciente.


ABSTRACT Brachial artery pseudoaneurysms are rare but can be associated with severe complications as ischemia of the upper extremity. We report a case of a brachial artery pseudoaneurysm in the crease of the elbow presenting as a pulsating mass with progressive growth over the past year. The ipsilateral hand was sightly cold and presented paresthesia. The lesion was due to inadvertent arterial puncture during venipuncture. The pseudoaneurysm was successfully treated with surgical resection and vascular reconstruction with a brachial to ulnar artery bypass and brachial to radial artery bypass with saphenous vein graft. The different therapeutic options available for brachial artery pseudoaneurysms are discussed, considering the anatomic characteristics and patients' symptoms.

ABSTRACT

Abstract Pseudoaneurysm of the ascending aorta (PAA) is a hazardous and potentially fatal cardiovascular disease. This condition is caused by the rupture of at least one layer of the vessel and contained by the remaining vascular layers or the surrounding mediastinal structures. We presented the surgical treatment of a patient with sepsis and large PAA and brachiocephalic trunk, which was compressing the brachiocephalic trunk leading to syncope.

ABSTRACT

RESUMEN El pseudoaneurisma es aquel hematoma pulsátil y encapsulado producido tras la rotura de todas las túnicas del vaso y contenido por tejidos vecinos circundantes. Es considerado una complicación tardía en la cirugía protésica aorto-ilíaca. Se presenta un paciente de 72 años al que se le realizó un baipás aorto-bifemoral 13 años atrás, y que posteriormente se le diagnosticó un pseudoaneurisma para-anastomótico que se dejó evolucionar por presentar varias comorbilidades asociadas. Transcurridos 2 años fue necesario realizarle una intervención quirúrgica por presentar crecimiento excesivo de la tumefacción y complicación isquémica con necrosis cutánea. La aparición de un pseudoaneurisma está relacionada con el sexo, el material protésico y con el tiempo que transcurre desde la cirugía. El seguimiento ultrasonográfico durante el postoperatorio es primordial para identificar tempranamente esta complicación.


ABSTRACT Pseudoaneurysm is that pulsatile and encapsulated hematoma produced after the rupture of all vessel layers and contained by surrounding neighboring tissues. It is considered a late complication in aorto-iliac prosthetic surgery. We present a 72-year-old patient who underwent an aorto-bifemoral bypass grafting 13 years ago, and who was subsequently diagnosed with a para-anastomotic pseudoaneurysm that was allowed to evolve due to presenting several associated comorbidities. After two years, it was necessary to perform a surgical intervention due to the excessive growth of the swelling, and ischemic complication with skin necrosis. The appearance of a pseudoaneurysm is related to sex, prosthetic material as well as the time that elapses since the surgery. Ultrasound follow-up during the postoperative period is essential for an early identification of this complication.

Resumen Objetivo: El objetivo del trabajo es presentar una opción terapéutica adecuada para los pseudoaneurismas de la femoral profunda secundarios a trauma penetrante, así como realizar una revisión de la literatura sobre el manejo en estas patologías. Caso clínico: Paciente masculino de 21 años quien 5 meses previos a su valoración sufre una herida por arma punzocortante en el muslo izquierdo, desarrollando aumento de volumen el sitio de la lesión, dolor y limitación al movimiento. Se diagnostica un pseudoaneurisma de la arteria femoral profunda de 2,3 cm x 2,1 cm x 2,7 cm y un hematoma adyacente de 13,5 cm x 12,6 cm x 23 cm. Se realiza exclusión del pseudoaneurisma mediante cirugía endovascular con coils, posteriormente se evacúa el hematoma adyacente. Resultados: El paciente egresa al tercer día posoperatorio con mejoría de la sintomatología, antibioticoterapia y analgesia. Discusión y Conclusión: En el caso presentado la exclusión del pseudoaneurisma mediante coils facilitó el control de éste y la evacuación del hematoma adyacente, disminuyendo el riesgo de sangrado. Por lo que consideramos adecuada esta conducta terapéutica en pseudoaneurismas de la femoral profunda.


Aim: The aim of this paper is to present a case of a deep femoral artery pseudoaneurysm secondary to a penetrating trauma in the left thigh, its management and a literature review. Clinical Case: 21-year-old male referred to the emergency department of our institution 5 months after he was injured with a knife on his left thigh, with severe local swelling, local pain, and difficulty to the mobilization of the left leg. A 2.3 cm x 2.1 cm x 2.7 cm deep femoral artery pseudoaneurysm was diagnosed with a 13.5 cm x 12.6 cm x 23 cm adjacent hematoma. Endovascular exclusion was made with coils and evacuation of the hematoma with open surgery. Results: The patient was discharged on the third day postop without pain and walking with antibiotics and follow-up to a month did not reveal any complications. Discusion and Conclusion: Exclusion with coils is an adequate management in deep femoral pseudoaneurysms that facilitates the evacuation of the hematoma lowering the risk of bleeding.

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

PURPOSE@#To explore the diagnosis and treatment of traumatic external carotid branch pseudoaneurysms.@*METHODS@#Eleven cases of traumatic external carotid artery branch pseudoaneurysms were admitted in our hospital. Digital subtraction angiography was performed in all patients. It revealed that the pseudoaneurysms originated from the internal maxillary artery in 5 cases, superficial temporal artery in 5 cases and occipital artery in 1 case. Five cases of internal maxillary artery pseudoaneurysms and 2 cases of superficial temporal artery pseudoaneurysms were treated by embolization; the other 3 cases were surgically resected.@*RESULTS@#Complete cessation of nasal bleeding was achieved in all the 5 pseudoaneurysms of internal maxillary artery after the endovascular therapies. Scalp bleeding stopped and scalp defect healed up in 2 patients with superficial temporal artery pseudoaneurysms treated by interventional therapy. All patients were followed up for 0.5-2.0 years without recurrence of nosebleed and scalp lump.@*CONCLUSION@#For patients with repeated severe epistaxis after craniocerebral injury, digital subtraction angiography should be performed as soon as possible to confirm traumatic pseudoaneurysm. Endovascular therapy is an effective method for traumatic internal maxillary artery pseudoaneurysms. For patients with scalp injuries and pulsatile lumps, further examinations including digital subtraction angiography should be performed to confirm the diagnosis. Surgical treatment or endovascular therapy for scalp traumatic pseudoaneurysm is effective.

ABSTRACT

Los seudoaneurismas de las arterias de la mano son infrecuentes, se han publicado escasos reportes de casos de adultos, secundarios a un trauma cerrado o abierto. El diagnóstico se confirma mediante ecografía Doppler y otros estudios complementarios. Si no se trata, se puede complicar con trombosis, embolia distal de arterias digitales, lesión nerviosa o necrosis. La cirugía es el tratamiento recomendado y consiste en resección del segmento dañado y ligadura simple, arteriorrafia o reconstrucción vascular con injerto. Los objetivos de este reporte son describir un caso de seudoaneurisma hipotenar secundario a una herida penetrante en un niño y, dada la rareza de este cuadro, revisar, de manera no sistemática, la bibliografía actual. Nivel de evidencia: IV


Pseudoaneurysms of the arteries of the hand are infrequent; few reports of cases in adult patients, secondary to closed or open trauma, have been found in the literature. The diagnosis is confirmed by Doppler ultrasound and other complementary studies. If it is left untreated, the complications include thrombosis, distal digital artery embolism, nerve injury, or necrosis. Surgery is the recommended treatment and consists of resection of the pseudoaneurysm and simple ligation, arteriorraphy, or vascular reconstruction with graft. The objective of this report is to describe a case of hypothenar pseudoaneurysm due to penetrating injury in a pediatric patient, and, due to the rarity of this condition, to conduct a non-systematic review of the current literature. Level of evidence: IV

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

Abstract Mycotic pseudoaneurysms of the superficial femoral artery (SFA) are rare and are usually secondary to colonization of an atherosclerotic plaque during an episode of bacteremia. We describe the case of a 68 year-old diabetic male who presented to the Emergency Department with pyrexia and a painful expanding mass in the left thigh. He had a history of diarrhea and had been treated 16 days earlier for an SFA pseudoaneurysm that had been excluded with a covered stent with no adjunctive antibiotic therapy. Angio CT showed an abscess surrounding femoral vessels and stent thrombosis. Under general anesthesia, we performed extensive debridement, removal of the endovascular material, SFA ligation, and empirical antibiotic therapy. Blood and tissue cultures were positive for Escherichia coli. At the 3-months follow up visit, the patient reported he had no claudication. In selected patients, mycotic pseudoaneurysms can be treated by SFA ligation.


Resumo Pseudoaneurismas micóticos da artéria femoral superficial (AFS) são raros, e geralmente são secundários à colonização de uma placa aterosclerótica durante bacteremia. Relatamos o caso de um paciente masculino diabético de 68 anos que chegou ao Serviço de Emergência com pirexia e massa expansiva dolorosa na coxa esquerda. Apresentava histórico de diarreia e havia sido tratado 16 dias antes para pseudoaneurisma da AFS, que foi excluído com stent coberto e sem antibioticoterapia adjuvante. A angiotomografia computadorizada demonstrou um abscesso ao redor dos vasos femorais e trombose do stent. Sob anestesia geral, realizamos desbridamento extenso, remoção do material endovascular, ligadura de AFS e antibioticoterapia empírica. Culturas de sangue e tecidos foram positivas para Escherichia coli. Na consulta de seguimento aos 3 meses, o paciente negou claudicação. Em pacientes selecionados, pseudoaneurismas micóticos podem ser tratados com ligadura de AFS.
