Gastropericardial fistula: A successfully operated heart code.

Gastropericardial fistula is a rare, extremely serious and life-threatening condition. Its most common aetiology is secondary to iatrogenic injury following gastric surgery. Clinical manifestations may be non-specific with precordial pain, simulating an acute coronary syndrome, and may be accompanied by electrocardiogram abnormalities. Diagnosis is made by thoracoabdominal computed tomography (CT) with oral and intravenous contrast. Treatment is surgical and consists of repair of the anomalous communication. We present the case of an 81-year-old male patient with gastropericardial fistula who underwent surgery, with the aim of reviewing the diagnosis and the appropriate therapeutic strategy.

Successful transvaginal repair of a vesicouterine fistula with delayed presentation.

A G4P4 woman in her 30s with a type II vesicouterine fistula, as defined by the Jozwik classification system, presented with symptoms of menouria, vaginal menses and urinary incontinence 8 years after caesarean delivery, the time of probable origination of the fistula tract. Transvaginal ultrasound identified a fistula tract communicating between the bladder and uterus, a rare finding that many years remote from caesarean delivery. Traditional surgical technique includes laparoscopic, abdominal and endoscopic methods of repair, sometimes using a transvesical approach. Transvesical repair can be associated with subsequent inpatient hospital stays and prolonged catheterisation. Our technique proposes a transvaginal surgical approach as an outpatient procedure with decreased operating time (40 min), postoperative pain and catheterisation requirement. It is the authors' belief that a transvaginal approach is less invasive and allows for better preservation of the uterus for future pregnancies and vaginal deliveries, as desired by the patient.

Spontaneous rupture of the right aortic sinus resulting in a sterile aorto-atrial fistula in a pet rabbit (Oryctolagus cuniculus).

Aortocardiac fistula is a broad term used to describe defects between the aorta and other cardiac chambers that can occur in humans and animals. A 1.5-year-old, 1.7 kg, male castrated Holland lop rabbit (Oryctolagus cuniculus) was presented for a two-week history of a heart murmur with corresponding cardiomegaly on radiographs. Physical examination confirmed a grade-V/VI continuous heart murmur on the right sternal border with a regular rhythm and a gallop sound. Echocardiography revealed an aortic-to-right-atrial fistula causing severe left-sided volume overload. Based on the echocardiographic findings, rupture of the right aortic sinus was suspected. Due to the poor prognosis, euthanasia was elected. On necropsy, a fistula was found connecting the right aortic sinus with the right atrium, without evidence of an inflammatory response nor evidence of an infectious etiology. The sudden onset of a heart murmur supported acquired fistulation from a ruptured aortic sinus (also known as the sinus of Valsalva), though a congenital malformation could not be completely excluded.

Echocardiographic and pathologic identification of an aorto-left atrial fistula secondary to infective endocarditis in a canine patient.

A dog was presented for lameness, fever, and extreme lethargy. On physical exam, a new heart murmur, arrhythmia, and joint effusion were detected. These findings were not detected two months prior. A diagnostic work-up confirmed septic suppurative inflammation in multiple joints. Echocardiogram revealed aortic valvular endocarditis along with a communication, as a consequence of a fistula, that extended from just below the aortic sinotubular junction to the left atrial lumen. Due to a poor prognosis, humane euthanasia was elected. Necropsy and histopathology confirmed infective endocarditis of the aortic valve and an aorto-left atrial fistulous tract extending from the left coronary sinus of the aortic valve to the lumen of left atrium.

An unusual cause of acute coronary syndrome: thrombosis of right coronary artery to right atrium fistula.

Coronary arterial fistulae are rare, but it is one of the most common coronary artery anomalies. Most of the cases are asymptomatic in younger patients unless it is large and of haemodynamic significance. The incidence of thromboembolic complications usually increases with age. We report a case of a young male in his early 20s presenting with central chest pain. Coronary computed tomographic angiography revealed acute coronary syndrome due to a fistula between right coronary artery and right atrium occluded by thrombus. After discussion with coronary and congenital heart multidisciplinary team, a consensus was agreed that we should manage him conservatively with anticoagulant and antiplatelet therapy and a 3-month follow-up strategy that included repeating cardiac imaging. After a year, his anticoagulation and antiplatelet medication was discontinued.

Cerebrospinal fluid hypotension following fall in a child: Case report / Hipotensión del líquido cefalorraquídeo tras caída en un niño: caso clínico

CSF hypotension arises in the context of a leak of CSF which causes negative intracranial pressure. Sacral fractures result from high-energy trauma which are frequently underdiagnosed. A ten-year-old boy presented with hip pain, after a fall. He mobilized both lower limbs, reported no leg pain, irradiation nor lack of sphincter control. The neurological examination was normal. When asked to stand, he began biparietal headache, nausea and vomiting, which improved laying down. CT scan showed an occult intrasacral meningocele; the MRI revealed collections of CSF along the spine, a S3 fracture with potential laceration of the meningocele and opening of a CSF fistula. Our diagnosis was the CSF hypotension, secondary to the fistula opening. The diagnosis was challenging. The child first presented with symptoms of CSF hypotension without evident cause. The discovery of the meningocele led us to hypothesize the opening of a fistula, a rare diagnosis, later confirmed by MRI (AU)

La hipotensión del LCR surge en el contexto de una fuga de dicho líquido que causa presión intracraneal negativa. Las fracturas del sacro son originadas por traumatismos de alta energía que a menudo no se diagnostican. Un niño de diez años acudió con dolor de cadera tras una caída. Podía mover las piernas, no reportando ningún dolor en las mismas, ni irradiación o falta de control del esfínter. El examen neurológico resultó normal. Cuando se le pidió que se pusiera de pie comenzó a sufrir cefalea biparietal, náuseas y vómitos, que mejoraban al tumbarse. La TC mostró un meningocele intrasacro oculto. La RM reveló rastros de LCR a lo largo de la columna, fractura en S3 con laceración potencial del meningocele y apertura de una fístula de LCR. Nuestro diagnóstico fue hipotensión de LCR, secundaria a la apertura de la fístula. El diagnóstico resultó difícil. El niño presentó síntomas de hipotensión del LCR sin causa evidente. El descubrimiento del meningocele nos llevó a conjeturar la apertura de una fístula, un diagnóstico infrecuente que fue confirmado posteriormente mediante RM (AU)

Rol de las imágenes en la patología arterial no ateroesclerótica poco frecuente en el abdomen / Role of images in rare vascular pathology in the abdomen

Resumen La patología arterial no ateromatosa constituye un grupo de patologías poco frecuentes, pero de gran importancia debido a su morbilidad y mortalidad asociadas. La presentación clínica de estas entidades es inespecífica, por lo que el estudio inicial con imágenes es fundamental. Debido a esto, es muy importante reconocer los signos radiológicos característicos de cada una en las diversas modalidades imagenológicas para poder sospechar y orientar el diagnóstico.

Abstract Non-atheromatous arterial pathology constitutes a group of infrequent pathologies but of great importance due to their associated morbidity and mortality. In general, the clinical presentation of these pathologies is quite nonspecific, so the clinician decides to perform imaging studies thinking of more common entities. It is for this reason that it is very important to recognize characteristic radiological signs in the various imaging modalities to be able to suspect and orient a pathology of this kind.

Fístula perilinfática de causa traumática. Reporte de un caso pediátrico / Traumatic perilymphatic fistula. Report of a pediatric case

La fístula perilinfática de causa traumática es una patología poco habitual. En general, es causada por lápices, hisopos, hebillas de pelo y fósforos.Dentro de los síntomas más frecuentes, los pacientes pueden presentar hipoacusia y vértigo. Su diagnóstico requiere un examen físico completo que incluya otomicroscopía, audiometría ytomografía computada de ambos peñascos. El tratamiento depende de la sintomatología del paciente. En general, en un principio, es conservador, pero puede llegar a requerir cirugía. Se presenta un caso clínico de un niño de 6 años con fístula perilinfática secundaria a un traumatismo del oído izquierdo por un hisopo, que requirió tratamiento quirúrgico

Traumatic perilymphatic fistula is an unusual pathology. Generally caused by pencils, swabs, hair buckles, and matches. Among the most frequent symptoms, patients can present hearing loss and vertigo.Diagnosis requires a complete physical examination that includes otomicroscopy, audiometry and computed tomography of both boulders. Treatment depends on the patient's symptoms. In general, it is conservative at first, but may require surgery.We present a clinical case of a 6-year-old boy with perilymphatic fistula secondary to left ear trauma due to swab, which required surgical treatment

Fístula retroauricular complicada asociada a disgenesia mayor del oído externo. Reporte de un caso / Complicated retroauricular fistula with external ear major dysgenesis. A case report

Las anomalías de las hendiduras y arcos branquiales son la segunda causa más común de lesiones congénitas de cabeza y cuello en niños. Representan el 8% de todas las malformaciones congénitas y el 30% de las de cabeza y cuello. Pueden permanecer asintomáticas o manifestarse como una tumefacción y asociarse a infecciones recurrentes supuradas en la región preauricular, subauricular o retroauricular, en las regiones de la parótida y/o del cuello. Fueron reportados casos asociados a malformaciones óticas.La tomografía computada de alta resolución y la resonancia magnética con gadolinio pueden ayudar al diagnóstico. El tratamiento médico antibiótico está indicado ante una infección aguda, además de incisión y drenaje en los procesos abscedados. El tratamiento definitivo es quirúrgico con la extirpación completa de la lesión. Se presenta a un niño de 6 años de edad con infección aguda en la región retroauricular derecha en el oído disgenésico

Branchial cleft anomalies are the second most common congenital head and neck lesions in children. The first congenital head and neck lesion is thyroglossal duct cysts. First branchial cleft anomalies are rare congenital head and neck malformations (8% of branchial cleft anomalies).The initial clinical manifestation was recurrent infections and/or discharge in auricular, periauricular, parotid or upper neck regions. These anomalies are extremely rare and other associated facial malformations were described.The computed tomography and magnetic resonance can help the diagnosis. The antibiotic treatment is indicated in acute infection. Also, incision and drainage are recommended in abscessed processes.In this report, we present a case of retroauricular sinus infection in a 6-year-old child with congenital ear anomalies

Design of a temporoparietal fascial flap after a spontaneous nasal fistula unresolved by conventional approaches / Diseño de un colgajo de fascia temporoparietal después de una fístula nasal espontánea no resuelta por abordajes convencionales

We report the surgical management of a spontaneous and recurrent nasal fistula using a temporoparietal fascial flap for definitive treatment after several failed attempts to close the fistula by conventional approaches. Two formalin-fixed cadaveric human heads were also dissected to study the anatomy and surgical technique involved in the design of the temporoparietal fascial flap (AU)

Reportamos el manejo quirúrgico de una fístula nasal espontánea y recurrente utilizando un colgajo de fascia temporoparietal para el tratamiento definitivo después de varios intentos fallidos de cerrar la fístula mediante abordajes convencionales. También se diseccionaron 2 cabezas de cadáver humano y fijadas con formol para estudiar la anatomía y la técnica quirúrgica que intervienen en el diseño del colgajo de fascia temporoparietal (AU)

Fístula linfática cervical: complicaciones y manejo / Cervical chyle leak: complications and management

La fístula linfática cervical se produce por daño iatrogénico del conducto torácico en cirugías de cabeza y cuello. Ante la sospecha de una fístula linfática se debe iniciar rápidamente un manejo nutricional y seguimiento estrecho, ya que pueden tener consecuencias graves como inmunosupresión, compromiso metabólico y necrosis cutánea con exposición e incluso ruptura carotídea. A continuación se presenta el caso de un paciente con fístula linfática cervical que precisó reintervención quirúrgica para lograr el cese de la fístula

Chyle leak formation is produced by iatrogenic damage to the thoracic duct in head and neck surgeries. Given the suspicion of a cervical chyle leak, nutritional management and close follow-up should be initiated quickly, since they can have serious consequences such as immunosuppression, metabolic compromise and skin necrosis with exposure or even carotid rupture. We report the case of a patient with cervical chyle leak that required surgical reexploration to reach the chyle leak closure

Absceso pulmonar con fístula neumocutánea / Pulmonary abscess with pneumocutaneous fistula

Lung abscess is a rare entity in pediatric age, but it generates significant morbidity. Even less frequent is the presence of this with spontaneous drainage to the skin, generating an abscess in the chest wall, reason for consultation, of the present clinical case. Subsequently, the presence of lung abscess with extension to the chest wall without pleural involvement was documented by imaging studies, an extremely rare and unusual entity, with only one case described in the world literature within our reach and in an adult patient.

El absceso pulmonar es una entidad infrecuente en la edad pediátrica, pero que genera una morbilidad importante. Aún menos frecuente es la presencia de este con drenaje espontáneo a piel, generando un absceso en pared torácica, motivo de consulta, del presente caso clínico. Posteriormente y por estudios imagenológicos se documentó la presencia de absceso pulmonar con extensión a pared torácica sin afectación pleural, una entidad extremadamente rara e inusual, con un solo caso descrito en la literatura mundial a nuestro alcance y en un paciente adulto.
