Accidental insertion of double-J in the inferior vena cava in a patient with retroperitoneal fibrosis: a case report.

Background: Implantation of the double-J stent is a common procedure in urology. The function of this device is to maintain the flow of urine from the ureteropelvic junction to the urinary bladder when the ureter is blocked or partially blocked for some reason. Once in place, the stent may cause low back pain, hematuria, symptoms of urinary irritation, a reduction in labor capacity, infection and calcification which are side effects that are easy to manage. However, severe complications can occur, such as the insertion of the stent into the circulatory system, such as the vena cava, which, although uncommon, is one of the most severe and difficult to manage. This work reports the case of a patient with the accidental insertion of a double-J stent into the inferior vena cava. Case Description: An 80-year-old female patient with repeated urinary tract infections using a double-J stent due to stenosis of the right distal ureter distal presenting retroperitoneal fibrosis secondary to previous radiotherapy. The patient had Lynch syndrome, ovarian and uterine cancer, colorectal cancer, and nephrolithiasis. She had been submitted to multiple previous surgeries. Due to the possibility of viral infection by coronavirus disease 2019 (COVID-19), chest computed tomography was performed, which suggested the insertion of the double-J stent in the inferior vena cava, confirmed by abdominal computed tomography. As the distal end of the stent was within the bladder, the decision was made to remove the stent by cystoscopy, with the implantation of a new stent using fluoroscopic control for the confirmation of its trajectory. No intraoperative or postoperative complications occurred and the patient is currently in outpatient follow-up. Conclusions: Situations such as this require caution during the implantation of the drainage device, with the occurrence of resistance indicating the need to discontinue the procedure and perform a new assessment with imaging exams. No intraoperative or postoperative complications occurred and the patient is currently in outpatient follow-up.

Manejo conservador de pseudoaneurisma de vena cava iatrogénico / Conservative management of iatrogenic vena cava pseudoaneurysm

Introducción: los pseudoaneurismas de vena cava infrarrenal (VCI) son una patología infrecuente, sin tratamiento estandarizado; la mayoría, secundarios a traumatismos abdominales. Presentan una mortalidad del 20-57 %. Su manejo debe ser individualizado, con opciones como conservador, quirúrgico o endovascular. Caso clínico: varón de 23 años con cardiopatía congénita compleja que ingresa por síncope extrahospitalario con posterior aleteo auricular e inestabilidad hemodinámica. Durante el procedimiento de ablación presenta shock hemorrágico. Precisa drogas vasoactivas y transfusión masiva. Tras su estabilización, se realiza angio TAC abdominal en el que se visualiza hematoma retroperitoneal dependiente de VCI sin hemorragia activa. Dada la comorbilidad del paciente y la estabilidad hemodinámica, se decide tratamiento conservador y control radiológico. En el angio TAC a los 15 días se visualiza pseudoaneurisma de VCI. Decide mantenerse actitud conservadora, retirar la anticoagulación y realizar revisiones periódicas. Se mantiene estable y se decide el alta, con vigilancia estrecha. En el control a los dos meses se objetiva completa resolución del pseudoaneurisma. Discusión: dada la complejidad de la patología, la estabilidad hemodinámica y las comorbilidades del paciente, se optó por manejo conservador, sin descartar otras opciones terapéuticas si presentaba empeoramiento clínico o radiológico. El tratamiento del pseudoaneurisma de VCI debe individualizarse, priorizando la clínica y la estabilidad del paciente y vigilando la evolución de la lesión con control radiológico estrecho.(AU)

Background: infrarenal cava vein (ICV) pseudoaneurysms are an infrequent pathology, without standardized treatment. Most secondary to abdominal trauma and may associate arterial injuries. Presenting a mortality of 20-57 %, which has not been reduced, despite advances in treatment. Iatrogenic IVC injuries can develop retroperitoneal hematomas and pseudoaneurysms. Its management must be individualized, with options such as conservative, surgical or endovascular. Case report: a 23-year-old male with complex congenital heart disease was admitted due to out-of-hospital syncope with subsequent atrial flutter and hemodynamic instability. During the ablation procedure, he presented hemorrhagic shock requiring doses of vasoactive drugs and massive transfusion. After stabilizing the patient, an abdominal angio-CT was performed, visualizing an IVC-dependent retroperitoneal hematoma with no signs of active bleeding. Given the patient's comorbidity and hemodynamic stability, conservative treatment and radiological control were implemented. CT angiography at 15 days shows IVC pseudoaneurysm. It was decided to maintain a conservative attitude, withdraw anticoagulation and periodic check-ups. Remaining stable, discharge is decided, with close monitoring. At the two months check-up, complete resolution of the pseudoaneurysm is observed. Discussion: given the complexity of the pathology, the patient's hemodynamic stability and comorbidities, conservative management was chosen, without ruling out other therapeutic options if presented with clinical or radiological worsening. The treatment of IVC pseudoaneurysm must be individualized, prioritizing the patient's symptoms and stability and monitoring the evolution of the lesion with close radiological control.(AU)

An Unusual Case of Fatal Thoracoabdominal Gunshot Wound without Diaphragm Injury.

In case of thoracoabdominal gunshot wounds (GSW), diaphragmatic lesions are common autopsy findings. In these cases, the bullet's path involves both the thorax and the abdomen, so the diaphragm (the muscle that separates the two cavities) is frequently damaged. In the present report we illustrate a very unusual autopsy finding, came up after a man was shot twice and affected by a lethal thoracoabdominal gunshot wound. In particular, as expected based on CT scans, the corpse exhibited a thoracic-abdominal path and a retained bullet in the abdomen, but no diaphragmatic lesions or hemorrhagic infiltrations of this muscle have been detected during the autopsy. After a scrupulous examination and the section of all the organs, the intracorporeal projectile's path was reconstructed, inferring that the thoracoabdominal transit of the bullet extraordinarily had occurred in correspondence of the diaphragmatic inferior vena cava's ostium, thus exploiting a natural passage without damaging the diaphragmatic muscle.

Anomalías de vena cava inferior: revisión e implicaciones quirúrgicas / Inferior vena cava anomalies: review and surgical considerations

Las anomalías de vena cava inferior (VCI) son el resultado de alteraciones en las diferentes etapas de un complejo proceso embrionario. A pesar de ser entidades poco frecuentes, con escasa o nula repercusión clínica y usualmente reportadas a partir de hallazgos incidentales, su detección es de gran importancia debido a las repercusiones clínicas y quirúrgicas asociadas con su presencia. Las alteraciones hemodinámicas generadas por estas variantes anatómicas constituyen factores predisponentes para el desarrollo de otras patologías concomitantes que requerirán un tratamiento específico. Tanto la falta de conocimiento de estas malformaciones vasculares o los errores diagnósticos relacionados pueden generar consecuencias graves con resultados imprevisibles.(AU)

Congenital anomalies of the inferior vena cava (IVC) are the result of alterations in the different stages of a complex embryonic process. Despite being uncommon, with little or no symptomatology and usually reported from incidental findings, their diagnosis is of great importance due to the clinical and surgical implications associated. The hemodynamic changes caused by these anatomical variants are predisposing factors for the development of other concomitant diseases that require a specific treatment. The lack of knowledge or diagnostic errors of these vascular malformations may cause serious consequences with unpredictable results.(AU)

Why optional inferior vena cava filters are not always retrieved? A real world 19 years experience in a Swiss tertiary care university hospital.

BACKGROUND: inferior vena cava filters (IVCF) are widely used to prevent thromboembolic events in patients not suitable for anticoagulation (AC). Although new generations of filters are optional and therefore retrievable, most of them become permanent. Aim of our study was to evaluate real life IVCF management in a tertiary hospital including retrieval rates and reasons for permanent filtering. MATERIALS AND METHODS: Electronic charts from patients receiving IVCF in a Swiss university hospital, during 1999-2017, were retrospectively identified. Patients were classified in two groups, according to filter retrieval (RG) or not (NRG). Type and reasons of filter placement were assessed. Retrieval, complications, and mortality rates were calculated. Reasons of non-retrieval were analyzed. RESULTS: 920 patients received an IVCF during 1999-2017. Filters were retrieved in 372 patients (40.65%). Subjects in the NRG were significantly older, more chronically ill, and presented higher mortality rate at 12 months following filter insertion (29.60% vs. 4.30%; p < 0.001). Reasons for non-retrieval included lack of follow-up (22.34%), persistent contraindications to AC (20.51%), technical issues (17.40%), and severe morbidity with short life expectancy (17.22%). Overall, complication rates after filter placement was 18.58%. Most reported complication was filter thrombosis (15.60%). CONCLUSIONS: In a real life setting, optional IVCF are still too often left in place indefinitely. Need for a systematic follow-up to ensure prompt filter retrieval is warranted. IVCF are not retrieved mostly in chronically and more severely ill patients, likely accounting for higher mortality in these subjects.

Resección hepática extendida con vena cava inferior por colangiocarcinoma intrahepático: presentación de 2 casos / Extended hepatic resection with inferior cava vein for intrahepatic cholangiocarcinoma: presentation of two cases

Resumen Introducción: El colangiocarcinoma intrahepático (CIH) corresponde al segundo tumor hepático primario y la resección quirúrgica es la única alternativa válida para el tratamiento curativo de esta enfermedad. Reporte de casos: Describimos 2 paciente portadores de CIH con compromiso de vena cava inferior (VCI) que fueron sometidos a resección en Clínica Alemana de Santiago (CAS). Ambas pacientes son de género femenino de 39 y 47 años de edad. Ambas fueron sometidas a resección mayor hepática izquierda, asociada a resección del segmento I y extendida a VCI. La reconstrucción de la VCI fue realizada con parche pericárdico bovino y cierre primario respectivamente. El período desde el posoperatorio hasta el alta, fue de 13 y 23 días respectivamente. Discusión: Aunque la reseccion quirúrgica es la única vía para la curación en el CIH, el compromiso de estructuras vasculares hacen que esto no sea posible. El manejo multidisciplinario asociado a una técnica meticulosa realizada por un equipo quirúrgico experimentado, hacen posible lograr buenos resultados.

Introduction: Intrahepatic cholangiocarcinoma is the second most common primary liver tumor and surgical resection the only valid curative treatment. Case reports: We describe two patients harboring an intrahepatic cholangiocarcinoma with cava vein involvement who underwent resection at Clinica Alemana of Santiago. Both patients were females with ages of 39 and 47 years old. Both patients underwent left liver resection, associated to resection of segment I and of a portion of cava vein. Reconstruction of resected portion of the cava vein was performed by using a pericardium bovine patch and primary closure respectively. Postoperative period was uneventfully being discharged at 13 and 23 days respectively. Discussion: Although surgical resection is the only way to get curativeness, frequent involvement of large vascular structures make treatment unfeasible. A multidisciplinary approach associated with a meticulous technique performed by an experienced surgical team make possible to accomplish the above objective.

Schwannoma pélvico con invasión al ventrículo derecho a través de la cava inferior. Presentación de un caso clínico / Pelvic schwannoma with right ventricle invasion through inferior cava. Clinical case presentation

RESUMEN Por lo general, los schwannomas del sistema nervioso central se originan en los nervios periféricos dentro de una estructura venosa. Son extremadamente raros y la literatura carece de publicaciones al respecto. Presentamos el reporte del 1er caso de schwannoma dentro de la vena cava inferior y que invade, a través de esta, la aurícula y ventrículo derecho. En el servicio de Cirugía Cardiovascular del Hospital Saturnino Lora, de Santiago de Cuba, se presentó una mujer de 50 años, con antecedentes de salud y síntomas progresivos de insuficiencia cardíaca derecha. La paciente fue intervenida quirúrgicamente con circulación extracorpórea y una evolución satisfactoria. Este tipo de lesiones deberán de ser abordadas por un personal calificado, con un amplio conocimiento de las técnicas de cirugía y de la anatomía vascular.

ABSTRACT Usually, a central nervous system schwannomas originates in the peripheral nerves inside a venous structure. They are extremely rare and there is a lack of literature or publications about it. We present the first case report of a schwannoma inside the inferior cava vein, invading the atrium and right ventricle, at the Cardiovascular Surgery Service of "Saturnino Lora" Hospital, in Santiago de Cuba. It was presented in a 50-year-old woman, with a health history of right heart failure progressive symptoms. The patient underwent surgery with extracorporeal circulation and a satisfactory evolution. This type of injuries should be managed by trained personnel, with extensive knowledge of surgical techniques and vascular anatomy.

Image analysis of Budd-Chiari syndrome in Henan province of China / 中华放射学杂志

Objective To investigate the distribution of the obstructive lesion of hepatic vein and inferior cava vein in patients with Budd-Chiari syndrome in Henan Province of China.Methods A total of 231 cases with Budd-Chiari syndrome were diagnosed by combination of three imaging techniques which either included colour Dopple ultrasound,multislice CT and vasography or colour Dopple ultrasound,MR angiography and vasography.All the hepatic veins,accessory hepatic veins and inferior vena cavae were imaged and their obstructions were detected and analysed.Results Out of the 231 patients there were 5 cases(2.2%)with simple obstruction of inferior vena cava with normal hepatic branches.Thirty-three cases(14.3%)had simple hepatic vein obstruction with normal inferior vena cava.The remaining 193(83.5%)cases had vein obstruction both in hepatic vein and inferior vena cava.Conclusion The most frequent form of Budd-Chiari symdrome in Henan province of China is the complex obstruction of inferior vena cava and heptic vein,and simple obstruction of inferior vena cava occurs the least.
