RESUMO
With persistent progress in donor-recipient evaluation criteria, organ procurement and preservation regimens and surgical techniques, the incidence of vascular complication after kidney transplantation has been declined, whereas it is still one of the most severe surgical complications of kidney transplantation, which may lead to graft loss and recipient death, and seriously affect the efficacy of kidney transplantation. Therefore, the occurrence, clinical manifestations, diagnosis and treatment strategies of common vascular complications after kidney transplantation, including vascular stenosis, arterial dissection, pseudoaneurysm, vascular rupture and thrombosis were reviewed in this article. In combination with the incidence, diagnosis and treatment of vascular complications after kidney transplantation in the First Affiliated Hospital of Xi'an Jiaotong University, diagnosis and treatment strategies for common vascular complications after kidney transplantation were summarized, aiming to provide reference for clinical diagnosis and treatment of vascular complications after kidney transplantation, lower the incidence of vascular complications, and improve clinical efficacy of kidney transplantation and survival rate of recipients.
RESUMO
Objective:To discuss the distinctive sonographic feature and the biological behavior of renal angiomyolipoma(RAML),and to provide the reference for the clinicians to make the accurate diagnosis of RAML.Methods:The clinical data of one patient with invasive classical RAML combined with pseudaneurysm formation were collected.The sonographic appearances were analyzed in conjunction with the pathological characteristics to clarify the biological behavior of RAML,and the relevant literatures were reviewed.Results:The patient,a 60-year-old female,visited the local hospital due to discomfort in the lumbar area,and received CT examination,and the CT examination results revealed a left renal mass,so the patient came to our hospital.The specialist clinical examinations and laboratory investigations were unremarkable.The ultrasound results indicated an enlarged left kidney with a cystic and solid mass at the upper pole,which featured pseudaneurysm formation(originating from the interlobar arteries);the enhanced CT image results suggested a high probability of upper pole renal carcinoma combined with aneurysmal formation within the tumor,alongside invasion into the left adrenal gland.The patient underwent laparoscopic radical left nephrectomy,and the postoperative pathology confirmed the diagnosis of invasive classical RAML.Conclusion:The classical RAML can exhibit the invasive biological behavior.The pseudaneurysm formation is a special sonographic manifestation of RAML,which can be challenging to differentiate from the other renal tumors.
RESUMO
Objective To discuss the methods,efficacy,and safety of endovascular treatment for ruptured pseudoaneurysm hemorrhage of internal carotid artery(ICA)after radiotherapy for nasopharyngeal carcinoma(NPC).Methods The clinical data of 21 patients with ruptured pseudoaneurysm hemorrhage of ICA after radiotherapy for NPC,who were admitted to the Affiliated Union Hospital,Fujian Medical University of China,were retrospectively analyzed.The patient's surgical strategies were analyzed,the therapeutic results and the clinical and imaging follow-up results were summarized.Of the 21 patients,covered stent implantation was carried out in 8,stent-assisted coil embolization was employed in 6,and direct occlusion of parent artery was adopted in 7.Results Successful endovascular treatment was accomplished in all the 21 patients.Excellent hemostatic effect was obtained immediately after surgery.Aneurysm neck residue was observed in 2 patients,and aneurysm body residue was seen in one patients.Postoperative bleeding recurred in 5 patients,in 4 of them the bleeding stopped after once more occlusion of the parent artery,and one patient developed internal leakage after covered stent implantation and the bleeding stopped after balloon dilation,and this patient died of unknown cause one month later.One patient developed coma after covered stent implantation,CT scan demonstrated subarachnoid hemorrhage and brain swelling,and this patient showed no improvement after treatment and was self-discharged from hospital.ICA occlusion was seen in 3 patients during follow-up period,and 2 patients did not receive a postoperative follow-up visit.In the 19 patients who were followed up,the mRS score was 0 point(n=9),1 point(n=6),2 points(n=2),5 points(n=1),and 6 points(n=1).Conclusion For the ruptured pseudoaneurysm hemorrhage of ICA after radiotherapy for NPC,endovascular treatment is highly safe with reliable efficacy.The covered stent implantation carries good short-term efficacy,but there are also problems such as aneurysm recurrence,internal endoleak,etc.The direct occlusion of parent artery may have more reliable long-term efficacy.(J Intervent Radiol,2024,33:304-308)
RESUMO
A 32-year-old woman was diagnosed with Takayasu's arteritis 5 years ago and underwent aortic valve replacement for aortic regurgitation 1 year ago. She had been taking Prednisolone and Azathioprine for Takayasu's arteritis, but these drugs were switched to subcutaneous Tocilizumab 4 months ago. One month ago, she had dyspnea on exertion, and 2 days ago, chest discomfort appeared, and she came to our hospital. Blood tests showed CRP 0.02 mg/dl, and echocardiography and CT showed perivalvular leakage and aortic root pseudoaneurysm, which led us to suspect aortic root pseudoaneurysm due to Takayasu's arteritis and to perform emergency surgery. Although a circumferential pseudoaneurysm was observed at the aortic root, no destruction of the prosthetic valve was observed. The suture from the previous surgery was attached to the sawing cuff of the prosthetic valve, and the prosthetic valve was not fixed to the aortic annulus and could be easily removed. The Bentall operation was performed using a bioprosthetic valve. The histopathological diagnosis was subacute infective endocarditis, and the patient was diagnosed with a pseudoaneurysm of the aortic root due to infection. The patient had a good postoperative course and was discharged home on the 19th day. We report a case of Takayasu's arteritis with valve annular abscess after AVR, which was treated surgically during biologic drug administration.
RESUMO
Resumen: Introducción: los aneurismas son dilataciones vasculares localizadas y permanentes de una arteria; en los pseudoaneurismas, las capas normales del vaso sanguíneo son reemplazadas por tejido fibroso. Debido a su baja incidencia, así como el desafío diagnóstico y terapéutico que representan; nuestro objetivo es presentar el caso clínico de un pseudoaneurisma de una arteria digital de la mano y realizar una revisión sistemática sobre dicha patología. Material y métodos: búsqueda bibliográfica en Medline, utilizando los términos «arteria digital¼ y «aneurisma¼. Se incorporaron estudios de patología de dilatación vascular que afecte la mano y los dedos. Se excluyeron trabajos con patología de afección proximal de la mano. Presentación de caso: paciente femenino de 79 años de edad, que posterior a herida cortante de quinto dedo de mano izquierda, desarrolla tumoración necrótica de rápido crecimiento. Contaba con ecografía y angiografía que sugerían hematoma. Se decidió manejo quirúrgico, durante el cual se observó que la tumoración involucraba arteria digital colateral cubital del quinto dedo. Se resecó lesión y segmento arterial involucrado. Cursó postquirúrgico sin complicaciones. Se confirmó el diagnóstico histopatológico de pseudoaneurisma de la lesión. Discusión: la etiología traumática es la causa más frecuente de los aneurismas digitales. Los factores de riesgo para los pseudoaneurismas incluyen lesiones penetrantes y alteraciones de la cascada de coagulación, como en el caso presentado. Conclusión: el pseudoaneurisma de una arteria digital es una patología rara y con gran variabilidad de manejo terapéutico. La resección quirúrgica de la lesión con la reconstrucción del flujo vascular, es el tratamiento recomendado.
Abstract: Introduction: aneurysms are focal and permanent dilations of an artery; in pseudoaneurysms, the normal layers of the blood vessel are replaced by fibrous tissue. Due to their low incidence, as well as the diagnostic and therapeutic challenge they represent; our objective is to present the clinical case of a pseudoaneurysm of a digital artery of the hand and to carry out a systematic review of this pathology. Material and methods: literature search in Medline, using the terms "digital artery" and "aneurysm." Studies of vascular dilation pathology affecting the hand and fingers were incorporated. Studies with pathology of proximal involvement of the hand were excluded. Case presentation: a 79-year-old female patient who, after a sharp force trauma to the fifth finger of the left hand, develops a rapidly growing necrotic tumor. She had ultrasound and angiography that suggested hematoma. Surgical management was decided, during which it was observed that the tumor involved ulnar collateral digital artery of the fifth finger. The lesion and the arterial segment involved were resected. Post-surgical course without complications. The histopathological diagnosis of pseudoaneurysm of the lesion was confirmed. Discussion: traumatic etiology is the most frequent cause of digital aneurysms. Risk factors for pseudoaneurysms include sharp force trauma and alterations of the coagulation pathways, as in the case presented. Conclusion: the pseudoaneurysm of a digital artery is a rare pathology with great variability of therapeutic management. Surgical resection of the lesion with vascular flow reconstruction is the recommended treatment.
RESUMO
Williams?Beuren syndrome is a rare genetic malformation with predilection for supravalvular aortic stenosis. Apart from cardiovascular malformation, hypocalcemia, developmental delay, and elfin facies, challenging airway make perioperative management more eventful. Association of infective endocarditis within the aortic arch and pseudoaneurysm formation is infrequent. We, hereby report a case of pseudoaneurysm formation and infective vegetation within the aortic arch in a patient with Williams syndrome and the role of transthoracic echocardiography in its perioperative management.
RESUMO
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.

@#Genuine infrapopliteal aneurysms are quite rare, in contrast to pseudoaneurysms. The aetiology of pseudoaneurysms related to external fixation is attributed to various theories, including direct vascular damage due to misplaced pins or wires, overshooting or misguidance during osteotomy, distraction at the corticotomy site during an Ilizarov procedure, and continuous abrasion of the vessel caused by a wire inserted in close proximity to an artery. Arteriography proves valuable in documenting lesions and assessing deeper pseudoaneurysms, particularly when contemplating reconstruction; it plays a crucial role in guiding management decisions. For significant tears and symptomatic aneurysms, resection and reconstruction are the gold standard treatment.
RESUMO
@#Aneurysms and pseudoaneurysm are commonly encountered with arteriovenous vascular access for haemodialysis. They are difficult complications to manage. Due to the limited number of vascular centers available, patients were unable to seek treatment until further complications arise. The technique of partial aneurysmectomy and primary repair was adopted as the method of repair in this study. A total of 20 cases underwent the surgery from 2019 to 2020. Among the 20 cases, one patient had two pseudoaneurysms at different location which requires her to undergo the procedure twice. The successful cannulation rate post repair was 70% whereas the overall complication rate was 35% which might be attributed to the small sample size. Overall, this study demonstrated that AVF aneurysm and pseudoaneurysm can be safely treated with this approach and can be done effectively in non-vascular centers by general surgeons.
RESUMO
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.

Resumo A artéria ulnar é o maior ramo terminal da artéria braquial, ela apresenta origem na fossa cubital e é coberta pelos músculos flexores do antebraço. Reportamos uma variação anatômica, na qual a artéria ulnar situava-se em posição superficial no antebraço. Por falta de conhecimento sobre essa variação, ocorreu a lesão após uma tentativa de punção venosa, a qual levou à formação de um pseudoaneurisma.
Abstract The ulnar artery is the larger terminal branch of the brachial artery. It originates in the cubital fossa and is covered by the flexor muscles of the forearm. We report an anatomic variant in which the ulnar artery was in a superficial position in the forearm. Since this variant was unknown, an attempted venous puncture injured the artery, causing formation of a pseudoaneurysm.
RESUMO
Abstract Transradial access is associated with fewer access site-related complications, earlier patient mobilization, and greater postprocedural comfort. Pseudoaneurysms are an extremely rare complication after transradial procedures and the radial artery itself is the most atypical arterial site of occurrence. We report a case in which a non-surgical, non-invasive, simple, and effective solution (prolonged pneumatic compression) was used to manage a radial artery pseudoaneurysm, a very rare and challenging complication of transradial procedures.
Resumo O acesso arterial transradial está associado a menos complicações relacionadas ao sítio de punção, com deambulação precoce do paciente e maior conforto pós-procedimento. O pseudoaneurisma é uma complicação extremamente rara após procedimentos transradiais, sendo a artéria radial, por si só, o sítio mais incomum para tal ocorrência. Relata-se um caso de um pseudoaneurisma de artéria radial, uma complicação rara e desafiadora, resolvido com êxito e de maneira simples, não invasiva e não cirúrgica (compressão pneumática prolongada).
RESUMO
Resumo As lesões traumáticas da aorta (LTA) torácica estão associadas a altas taxas de morbimortalidade. São classificadas de acordo com a extensão do dano, e a angiotomografia computadorizada tem as maiores sensibilidade e especificidade para identificar o grau de lesão e potenciais lesões associadas. As estratégias terapêuticas para LTA são baseadas no tipo de lesão, na extensão e nas lesões associadas. Pode auxiliar na definição de conduta também o grau de estabilidade do paciente, podendo ser manejo cirúrgico convencional, endovascular (TEVAR) ou conservador em casos selecionados. Entre os pacientes com anatomia vascular adequada, a cirurgia endovascular está associada a melhor sobrevida e a menos riscos. O objetivo deste artigo foi descrever uma série de quatro casos acompanhados em serviço terciário, em um estado com poucos serviços de alta complexidade. A terapêutica endovascular foi empregada como método preferencial. Os pacientes apresentaram evolução favorável sem complicações até a alta e encontram-se em acompanhamento ambulatorial.
Abstract Traumatic thoracic aortic injuries (TTAI) are associated with high rates of morbidity and mortality. They are classified according to the extent of damage and computed tomography angiography has the highest sensitivity and specificity for identifying the degree of injury and potential associated lesions. Treatment strategies for TTAI are based on the type and extent of injury and associated lesions. The patient's degree of stability can also help to define the choice of treatment, which can be conventional or endovascular surgery (EVAR) or even conservative management in selected cases. Among patients with adequate vascular anatomy, endovascular surgery is associated with better survival and fewer risks. The objective of this article is to describe a series of four cases followed up at a tertiary service in a Brazilian state that has few centers that provide high complexity care. Endovascular therapy was employed as the preferred method. All four patients had favorable outcomes, with no complications up to discharge, and are currently in outpatient follow-up.
RESUMO
Abstract Pseudoaneurysm of the palmar arch is a rare entity. Diagnosis is dependent on high clinical suspicion. We present a case referred to the emergency department, with a history of glass penetrating trauma to the palmar surface with a pulsatile mass and jet bleeding. Doppler ultrasound evidenced a partially thrombosed pseudoaneurysm. A CT angiography examination showed a saccular formation arising from the superficial palmar arch. A conventional surgical approach was indicated. A clinical suspicion must be ventured to arrive at the correct diagnosis. Imaging modalities are needed to identify the pseudoaneurysm and plan the treatment course. Nonetheless, the sequence of diagnosis is individual, because further evaluation with different imaging methods may not change the rationale for the intervention. In our experience, conventional surgical removal is preferable, due to its safety and well-established outcomes.
Resumo O pseudoaneurisma do arco palmar é uma entidade rara, cujo diagnóstico depende de alta suspeição clínica. Apresentamos o caso de um paciente encaminhado ao pronto-socorro com história de traumatismo penetrante por vidro na face palmar, com massa pulsátil e sangramento em jato. A ultrassonografia com Doppler evidenciou pseudoaneurisma parcialmente trombosado, e a angiotomografia demonstrou formação sacular originada do arco palmar superficial. Uma abordagem cirúrgica convencional foi indicada. Para prosseguir com o diagnóstico correto, essa suspeita clínica deve ser aventada. Modalidades de imagem são necessárias para identificar o pseudoaneurisma e planejar o curso do tratamento. No entanto, a sequência diagnóstica é individual, pois uma avaliação mais aprofundada, com diferentes métodos de imagem, pode não alterar o racional da intervenção. Em nossa experiência, a remoção cirúrgica convencional é preferível, visto sua segurança e seus resultados bem estabelecidos.
RESUMO
A Dorsalis Pedis Artery (DPA) pseudo aneurysm is one of the most uncommon peripheral arterial aneurysms. These aneurysms can cause distal embolization and thrombosis, leading to limb loss. However, their rupture is unusual1. Any type of injury or perhaps an iatrogenic intervention can cause a pseudo localized swelling of the dorsalis pedis artery, which is a relatively unusual condition. Whenever it presents as a non-pulsatile soft tissue mass in the presence or absence of a specific predeceasing event, it can lead to a difficult diagnostic dilemma2. The rare instance of an iatrogenic pseudo aneurysm of the dorsalis pedis artery which mimicked cellulitis of the right foot is discussed in this case report. Coil embolization of the proximal artery, and the aneurysm was successfully done by the intervention radiologist. After the procedure, collateral circulation was maintained. No ischemic symptoms such as intermittent claudication or pain at rest were observed. This approach may be useful in treating similar cases
RESUMO
Pseudoaneurysm of the common carotid artery (CCA) is exceptionally unstable and unpredictable; it mandates quick medical attention in order to circumvent neurologic sequelae or hemorrhage. Unanticipated rupture is extremely lethal and a potential provocation for the anesthesia caregiver. It is an arduous challenge for an anesthetist to establish emergency airway when a huge bleeding pseudoaneurysm is compressing and deviating the trachea, securing invasive lines in collapsing vessels, volume and vasopressor resuscitation in deteriorating hemodynamics in order to maintain cerebral perfusion without compromising other vital organs, arranging huge amount of blood and blood products in a short span of time, and transferring an exsanguinating patient for the rapid institution of cardiopulmonary bypass. Not only preoperatively it also necessitates appropriate neuromonitoring and neuroprotection during and after surgery. The association of unforeseen rupture of common carotid artery pseudoaneurysm secondary to the tubercular spine and lifesaving management by the rapid institution of cardiopulmonary bypass (CPB) is a rare occasion. To the best of the authors’ knowledge, there is not any similar case in the peer?reviewed literature. Therefore, the authors enumerate the clinical experience of an unexpected rupture of CCA pseudoaneurysm requiring lifesaving CPB and emphasize the “Timely Teamed Effort Approach” that can sustain a life in such an inevitable situation.
RESUMO
RESUMEN El pseudoaneurisma es un daño de la pared arterial, contenido por el hematoma circundante y estructuras vecinas, con flujo sanguíneo turbulento, que mantiene comunicación con la luz del vaso afecto. El presente estudio describe un paciente masculino de 57 años, que ingresa con diagnóstico de pseudoaneurisma de fístula arteriovenosa humero cefálica izquierda. Se realiza exéresis del falso aneurisma y creación de nueva fístula con prótesis vascular. El paciente reingresa al quinto mes con masa gigante pulsátil en sitio quirúrgico. Se realiza exploración, exéresis del pseudoaneurisma recidivante y nueva fístula humero-basílica izquierda con vena safena. Evoluciona favorablemente, realizándose diálisis dos años posteriores a la última cirugía sin complicaciones.
ABSTRACT Pseudoaneurysm is damage to the arterial wall, contained by the surrounding hematoma and neighboring structures, with turbulent blood flow, which maintains communication with the lumen of the affected vessel. The present study describes a 57-year-old male patient who was admitted with a diagnosis of left cephalic humeral arteriovenous fistula pseudoaneurysm. The false aneurysm wasexcised, and a new fistula was created with a vascular prosthesis. The patient was readmitted in the fifth month with a giant pulsatile mass at the surgical site. Surgical exploration was performed, excision of the recurrent pseudoaneurysm and a new left humerus-basilic fistula with saphenous vein. He is progressing favorably, performing dialysis two years after the last surgery without complications.
RESUMO
Resumen: Se informa la conducta anestésica de un caso de pseudoaneurisma ventricular izquierdo crónico secundario a complicación de infarto de miocardio transmural, complicación rara y casi siempre mortal. En este informe se describe el caso de una mujer de 60 años con insuficiencia cardíaca aguda a consecuencia de un infarto cardíaco ocurrido cinco meses atrás, que generó la complicación de la cual damos referencia. El manejo anestésico perioperatorio se logró al enfocarse en mantener una presión arterial estable para garantizar la perfusión cerebral y reducir el riesgo de ruptura completa del aneurisma hacia el espacio mediastinal.
Abstract: The anesthetic behavior of a case of chronic left ventricular pseudoaneurysm secondary to a complication of transmural myocardial infarction, a rare and almost always fatal complication, is reported. This report describes the case of a 60-year-old woman with acute heart failure, this is a consequence of a heart attack that occurred 5 months ago, which generated the complication of which we refer. Perioperative anesthetic management was achieved by focusing on maintaining a stable blood pressure to ensure cerebral perfusion and reduce the risk of complete rupture of the aneurysm into the mediastinal space.
RESUMO
@#Pseudoaneurysm which is also known as a false aneurysm is caused by extravasation of blood from the injured vessel wall which is contained by the surrounding soft tissue. It does not contain any layer of the vessel wall and can expand as more and more blood collects. We are reporting a case of an 18-year-old Indian gentleman who presented with complaint of left neck swelling after being involved in a motor vehicle accident. Examination showed a softly pulsating swelling at the angle of the left mandible. CT angiogram revealed a pseudoaneurysm of a branch of the left facial artery. The pseudoaneurysm was embolized by using histoacryl glue. Pseudoaneurysm should be considered as a differential diagnosis in patients with a pulsatile mass after trauma.
RESUMO
A 51-year-old man presented to our hospital with general fatigue and lower extremity edema due to right heart failure with severe coagulation disorder. He had undergone ascending aortic and total arch replacement for type A acute aortic dissection when he was 49 years old and had diagnosed with anastomotic pseudoaneurysm in the ascending aorta by computed tomography 1 year after the operation. Preoperative computed tomography showed an enlargement of the pseudoaneurysm. Since re-median sternotomy seemed to be high risk strategy for bleeding due to severe coagulation disorder, we decided to perform ascending aortic replacement through right thoracotomy. We opened the pseudoaneurysm and found an aorto-right atrium fistula. Redo ascending aortic replacement with direct closure of the fistula was successfully performed. The postoperative course was uneventful.
