Abstract Hydatid cyst in the cervical region is an extremely rare condition that can create challenges for anesthesiologists. Timely recognition of difficult airway and preparing the management plan is crucial to avoid life-threatening complications such as hypoxic brain damage. We describe a case of difficult airway management in a patient with massive cervical hydatid cyst. We used a low-dose ketamine-propofol sedation and lidocaine spray for local oropharyngeal anesthesia. Muscular relaxants were not used, and spontaneous breathing was maintained during intubation. Recognition, assessment, and perioperative planning are essential for difficult airway management in patients with cervical hydatid cyst.

Resumo O cisto hidático na região cervical é uma condição extremamente rara que pode criar desafios para os anestesiologistas. O reconhecimento oportuno das vias aéreas difíceis e a preparação do plano de manejo são cruciais para evitar complicações com risco de vida, como danos cerebrais hipóxicos. Descrevemos um caso de difícil controle das vias aéreas em um paciente com cisto hidático cervical maciço. Utilizamos sedação com cetamina-propofol em baixa dose e spray de lidocaína para anestesia local orofaríngea. Relaxantes musculares não foram utilizados e a respiração espontânea foi mantida durante a intubação. O reconhecimento, a avaliação e o planejamento perioperatório são essenciais para o manejo difícil das vias aéreas em pacientes com cisto hidático cervical.

Abstract Introduction: Hydatid cyst is a parasitic disease caused by Echinococcus granulosus, most commonly seen in the liver and lungs. The hydatid cyst is rarely seen in the heart and iliofemoral region, representing less than 2% of all cases. In this article, we report our cases of hydatid cysts in unusual loci. Methods: Between 2015 and 2018, 6 rare cases of hydatid cysts were diagnosed at the Cardiovascular Surgery Department of Harran University. Four of these patients had cardiac localization and two patients had their cysts located in the iliofemoral region, extending to the pelvic zone. All patients were female. Three patients had no other organ involvement. One patient with cardiac hydatid cyst underwent normothermic cardiopulmonary bypass + total pericystectomy + Cooley-like aneurysmectomy. Total pericystectomy was performed in three other patients with intrathoracic locus by normothermic cardiopulmonary bypass. Two patients who were referred to our clinic with palpable iliofemoral mass were evaluated with appropriate imaging methods and diagnosed accordingly. Multiple iliofemoral cysts were managed with pericystectomy and drainage by a single incision made over the inguinal ligament. Conclusion: Hydatid cyst disease can develop in cardiac chambers and inguinal region with or without hepatic or pneumatic involvement. Normothermic cardiopulmonary bypass can be safely used in patients with cardiac hydatid cysts, and capitonnage similar to ventricular aneurysm repair in patients with a widely involved cystic lesion can be very useful for the protection of ventricular functions.

A 20-year-old woman, without known pre-existent conditions presented with a history of dyspnea on exertion, and palpitations for 6 months. Vital signs, as well as cardiac and pulmonary examinations were normal. Routine blood tests were normal. The ECG showed nonspecific ST-T changes. The echocardiogram showed a left ventricle of normal size and function. A cystic image was shown in relation to the right ventricle, with displacement of the interventricular septum. These findings were confirmed on computed tomography. Additional cystic images on the liver or lungs were ruled out. On surgery, a cardiac hydatic cyst adhered to the pericardium next to the right ventricle was found. Puncture, drainage of the mass and surgical removal of cystic membranes were performed. The clinical course was uneventful. A four year follow up revealed no recurrence of the cyst.

Abstract Background and objectives: Hydatid cyst is a zoonotic disease caused by Echinococcus granulosus. The aim of our study is to present the clinical features of the patients who were treated for hydatid cyst, determine the interventional techniques and anesthesia methods used and review the occurred complications in detail. Methods: This study included 393 patients who were followed up and/or treated with the diagnosis of hydatid cyst between January 2013 and November 2018. The patients' data was evaluated retrospectively. Results: The mean age of the patients was 31.0 ± 17.2 years. Of the patients, 111 (28.4%) had more than one cyst and 36 (9.2%) patients had multi-organ involvement. Six of the patients refused the intervention or was transferred to another hospital. Among the remaining 387 patients, 335 (85.2%) received general anesthesia and intubation, 9 patients (2.3%) received general anesthesia and laryngeal mask airway, 39 patients (9.9%) received sedoanalgesia and 4 patients (1%) received regional anesthesia. Perioperative mortality was developed in one patient. The most common periopertaive complication was allergic reaction (1.5%), whereas the most common post-operative complications were atelectasis (3.3%) and biliary fistula (3%). The mean Intensive Care Unit stay (ICU) was 1.9 ± 1.1 days in patients requiring ICU. Recurrence during the 40 ± 17 months follow-up occurred in 8.4% patients. Conclusions: Anesthesiologists have an important role in the management of hydatid cyst patients. Patients should be evaluated exhaustively in terms of multi-organ involvement and the presence of more than one cyst in the same organ. The type of treatment procedure and the localization of the cysts determine the anesthetic management.

Resumo Introdução e objetivos: Cisto hidático é uma zoonose causada por Echinococcus granulosus. O objetivo do estudo é apresentar as características clínicas dos pacientes submetidos a tratamento de cisto hidático, determinar as técnicas intervencionistas e os tipos de anestesia utilizados, e revisar as complicações ocorridas, em detalhe. Método: Este estudo incluiu 393 pacientes que foram acompanhados e/ou tratados com o diagnóstico de cisto hidático, entre janeiro de 2013 e novembro de 2018. Os dados dos pacientes foram avaliados retrospectivamente. Resultados: A idade média dos pacientes foi 31,0 ± 17,2 anos. Do total de pacientes, 111 (28,4%) tinham mais de um cisto, e 36 (9,2%) apresentavam comprometimento em vários órgãos. Seis pacientes recusaram a intervenção ou foram transferidos para outro hospital. Dentre os 387 pacientes remanescentes, 335 (85,2%) receberam anestesia geral e intubação, 9 (2,3%) anestesia geral e máscara laríngea, 39 (9,9%) sedação e analgesia, e 4 (1%) anestesia regional. Houve um óbito no período perioperatório. Reação alérgica foi a complicação perioperatória mais comum (1,5%), e no pós-operatório observou-se mais atelectasia (3,3%) e fístula biliar (3%). O tempo médio de internação na Unidade de Terapia Intensiva foi 1,9 ± 1,1 dias para aqueles que necessitaram desses cuidados. Recidiva durante o seguimento de 40 ± 17 meses ocorreu em 8,4% dos pacientes. Conclusões: Os anestesiologistas têm um papel importante no tratamento dos pacientes com cisto hidático. Os pacientes devem ser avaliados exaustivamente em relação a comprometimento de vários órgãos e presença de mais de um cisto no mesmo órgão. O tipo de procedimento terapêutico e a localização dos cistos determinam a conduta anestésica.

INTRODUCCIÓN: El quiste hidatídico cardiaco es una patología infrecuente, producida por la llegada de Equinococcus granulosus a la circulación coronaria. MATERIALES Y MÉTODO: Hombre de 52 años, con antecedente de quiste hidatídico cardiaco operado hace 27 años, insuficiencia cardiaca y enfermedad coronaria. Presentó disnea progresiva de un año de evolución. Estudio con radiografía de tórax, ecocardiografía y tomografía computada que mostró imagen compatible con hidatidosis cardiaca recidivada en el ventrículo izquierdo, arteria pulmonar e hilio pulmonar izquierdo, rodeando por completo el tronco coronario común izquierdo y parte proximal de la arteria descendente anterior. Se constató fracción de eyección de ventrículo izquierdo aproximadamente de 30%. No se encontró evidencia de enfermedad hidatídica extracardiaca. Se decidió tratamiento quirúrgico. Se abordó por esternotomía media y en circulación extracorpórea, se observaron lesiones compatibles con quiste hidatídico multiloculado de ubicación miocárdica en ventrículo izquierdo, con incontables vesículas hijas. Se realizó quistectomía más periquistectomía hidatídica sin incidentes. Presentó hemorragia postoperatoria por lo que requirió reintervención quirúrgica precoz. Evolucionó favorablemente y fue dado de alta sin complicaciones. A seis años de seguimiento se encuentra asintomático, sin evidencia tomográfica y ecocardiográfica de recidiva. DISCUSIÓN: La hidatidosis es una zoonosis endémica en Chile. La ubicación cardiaca es infrecuente, correspondiendo al 0,5 al 2% de los casos. Suele asociarse a la presencia de quistes extracardiacos. La ubicación más frecuente es la pared libre del ventrículo izquierdo a nivel intramiocárdico. El tratamiento médico suele ser insuficiente, por lo que se recomienda la resección quirúrgica.

INTRODUCTION: Cardiac hydatid cyst is a rare disease caused by Echinococcus granulosus arrival of the coronary circulation. MATERIAL AND METHOD: 52 years old man with a history of cardiac hydatid cyst operated 27 years ago, heart failure and coronary artery disease. He presented with a history of one year of progressive dyspnoea. Study with chest radiography, echocardiography and computed tomography showed an image compatible with cardiac hydatid disease recurrence in relation to the left ventricle, pulmonary artery and anterior descending artery. Ejection fraction of the left ventricle was approximately 30%. No evidence of extracardiac hydatid disease was found and surgical treatment was decided. Addressed by median sternotomy and extracorporeal circulation, a multiloculated myocardial hydatid cyst, with hundreds of daughter vesicles of different size was found. Pericystectomy of the hydatid cyst was performed without incident. The patient presented postoperative bleeding which required early reoperation. Posteriorly, was discharged without complications. DISCUSSION: Hydatid disease is an endemic zoonosis in Chile. Heart location is infrecuent and correspond to 0.5 to 2% of the cases, usually associated with the presence of extracardiac cysts. The most common location is the free wall of the left ventricle at intramyocardial level. Medical treatment is often inadequate and surgical resection is recommended.

Abstract Among all cystic echinococcosis cases, only 0.5%-2% exhibit a cardiac involvement. Only 10% of these become symptomatic. Considering the long time interval between the start of infestation and symptoms to occur, it is hard to diagnose cystic echinococcosis. When detected, even if it is asymptomatic, intramyocardial hydatid cyst requires surgical intervention due to risks of spontaneous rupture and anaphylaxis. In literature, no case of hydatid cyst located in the coronary arterial wall has been reported. Twenty-two-year-old male patient with previous history of pulmonary cystic echinococcosis was referred to us with typical symptoms of coronary artery disease. Coronary cineangiography revealed proximal left diagonal artery (LAD) occlusion. Pre-operative transthoracic echocardiography of the patient planned to undergo coronary artery bypass grafting unveiled an intracoronary calcified cystic mass. In operation, the calcified cystic mass with well-defined borders and size of 2x2 cm located within wall of proximal segment of the LAD artery was excised and double bypass with left internal thoracic artery (LITA) and great saphenous vein grafts to the LAD and first diagonal arteries, respectively, was done. Pathological analysis of the mass revealed it to be an inactive calcified hydatid cyst. Echinococcal IgG-ELISA test was positive. 12-week oral albendazole treatment (2x400 mg/day) was launched postoperatively and the patient was discharged on 7th postoperative day.

Primary pelvic hydatid cysts are a rare entity and are often overlooked as a differential diagnosis of a pelvic-space-occupying lesion particularly in non-endemic regions. Unpreparedness and a hasty decision on the surgical approach may end in life-threatening complications and systemic dissemination of the disease. We report the case of a 55-year-old postmenopausal woman with a history of two previous unsuccessful surgeries to remove pelvic cystic lesions due to dense adhesions between the surrounding gut wall, bladder, and the cyst wall. Clinical and imaging findings failed to diagnose the nature of the cysts, and a laparotomy was contemplated. On the third surgical attempt, the clinical suspicion was considered and by meticulous dissection the cysts were removed thoroughly without undue complications. In the postoperative follow-up period there was no sign of disease recurrence or dissemination.

Hydatid disease is a parasitic infection whose etiologic agent is Echinococcus granulosus. Human is an accidental intermediate host and the most common site is the liver. The brain involvement is unusual and up to 75% of cases are described in the pediatric population. We present six children with cerebral hydatid disease admitted to the Pediatric Hospital J.P. Garrahan. All had neurological involvement on admission. The images showed single cystic lesion in the brain. They did not present involvement in other organs. Serology was negative in all cases. Medical and surgical treatment in all cases. The clinical outcome was favorable without sequelae in five of them and one had a residual paresis right faciobrachiocrural. This infection should be considered in the differential diagnosis of cystic tumor lesions of the central nervous system.

El compromiso cerebral es inusual, se describe que hasta 75% ocurre en población pediátrica. Se presenta una serie de seis niños con hidatidosis cerebral internados en el Hospital de Pediatría J. P. Garrahan. Todos presentaron compromiso neurológico al ingreso. Las imágenes mostraron lesiones quísticas únicas en el cerebro. No tuvieron compromiso de otros órganos. La serología fue negativa en todos los casos. El tratamiento fue médico-quirúrgico. La evolución clínica fue favorable sin secuelas en cinco de ellos y uno presentó una hemiparesia faciobraquiocrural derecha como secuela. Esta infección debe considerarse entre los diagnósticos diferenciales de lesiones tumorales quísticas del sistema nervioso central.

La hidatidosis o equinococosis hidatídica existe ampliamente en el mundo, pero no se encuentra en Cuba. El objetivo de la presente revisión es informar los resultados obtenidos en el tratamiento quirúrgico de la enfermedad hidatídica. Es un estudio retrospectivo, descriptivo en el cual se estudiaron 19 pacientes portadores de quistes hidatídicos. Se analizó: localización, número, procedimiento quirúrgico utilizado, complicaciones y mortalidad de los pacientes operados en tres años y tres meses de trabajo en el Hospital Universitario Al Wahda en Thamar, Yemen (2006-2009). Realizamos una detallada revisión bibliográfica de los aspectos básicos de la enfermedad hidatídica en su presentación clínica y localización, los aspectos esenciales del diagnóstico y las variantes de técnicas quirúrgicas y médicas. Los quistes únicos localizados en el lóbulo derecho del hígado predominaron seguidos de la pulmonar, los cuales son mayormente únicos. La cistectomía y pericistectomía parcial fue la operación mayormente realizada y la bilirragia externa, la fístula broncopleural precoz y la sepsis del sitio quirúrgico fueron las complicaciones encontradas en estos pacientes. No se presentó reacción anafiláctica durante el acto quirúrgico en ninguno de los casos; pero falleció un paciente. La hidatidosis quística debe ser conocida por los cirujanos cubanos que presten sus servicios en zonas donde esta afección aparezca o sea endémica para manejar adecuadamente estos pacientes(AU)

Hydatidosis or hydatidechinococcosis is widely spread worldwide except for Cuba. Nineteen patients who had hydatid cysts were studied. Design, retrospective and descriptivestudy. There were analyzed location, number, surgical procedure, complications and mortality rate among the patients operated on in three years and three months of operation of Al Wahda university hospital in Thamar, Yemen, from August 2006 to August 2009. A detailed literature review was made on the basic aspects of the hydatid disease, its clinical presentation and location, the essential aspects of diagnosis and the surgical and medical variants as well as the description of the surgical aspects seen in 19 patients with hydatid cysts.Single cysts located in the right lobe of the liver predominated followed by pulmonary location, mostly single ones. Cystectomy and partial pericystectomy was the most used surgery whereas external bilerrhagia, early pleural bronchial fistula and surgical site sepsis were the most observed complications in these patients. There was no anaphylactic reaction during the surgical act in any case. Just one patient died.Cystic hydatidosis should be known by the Cuban surgeons who render their services in areas where this disease is present or endemic in order to properly manage these patients(AU)

La hidatidosis es una zoonosis causada por la fase larval del Echinoccocus. Afecta principalmente a la región mediterránea, Sudamérica, África, Medio-Oriente, Australia y Nueva Zelanda. Afecta principalmente al hígado y al pulmón, aunque puede comprometer cualquier parte del cuerpo ya sea, por inoculación primaria o diseminación secundaria. Se presenta el caso de paciente de 54 años, sexo masculino, con antecedentes de hidatidosis pulmonar izquierda y abdominal subdiafragmática, diagnosticada hace 33 años. Ingresa por cuadro de paraparesia progresiva de extremidades inferiores, disminución de sensibilidad a la altura de T12 y lumbalgia sin otros signos ni síntomas asociados. La Tomografía axial computada mostró lesión tumoral paravertebral izquierda con signos de infiltración y destrucción de costilla y vértebra T12 a nivel de lámina y pediculo izquierdo, junto con lesión de 12 cm paravertebral anterior, con ingreso de quiste a lúmen aórtico, entre T4 y T6. Resonancia nuclear magnética muestra invasión hacia canal medular con signos de compresión. Se realizó laminectomía descompresiva con evacuación de vesículas. La evolución posterior es satisfactoria con recuperación de su paraparesia, logrando la bipedestación a los pocos días. Si bien el compromiso vertebral es raro, este se puede manifestar con dolor y síntomas secundarios a la compresión medular como paraparesia o paraplejia, déficit sensorial, reflejos osteotendíneos alterados, disfunción esfintérica y síndrome de cauda equina. Imágenes como tomografía axial computada y resonancia nuclear magnética, son necesarias para un efectivo diagnóstico y monitorización de la hidatidosis. El tratamiento de elección es la descompresión quirúrgica asociado a antihelmínticos para evitar la recurrencia.

The hydatid disease is a zoonoses caused by Echinoccocus’s larvae stage. The most affected regions are Meditarranea, South America, Africa, Mid West, Australia and New Zealand. Mostly infects the liver and the lungs, but any part of the body can be affected, by primary inoculation or dissemination. We present a case of a 54 years old, male patient, with 33 years history of pulmonary and abdominal hydatid disease. He is hospitalized for progressive paraparesia of lower limbs, paresthesia T12 root nerve and low back pain. Without any other symptoms. The CT scan shows a left paravertebral mass with infiltration signs and destruction of T12 vertebra and rib, and a 12 cm anterior paravertebral tumor with aorta invasion. Magnetic resonance imaging shows invasion of the spinal canal. Descompressive laminectomy was made with evacuation of the vesicles. Patient shows a satisfactory evolution, with a complete recovery of paresthesia and be able to walk. The vertebral hydatid disease is rare, but can be manifested by pain and medular compression symptoms, such a paraparesia, paresthesis, altered tendon reflexes, sphincter dysfunction and cauda equina syndrome. Imaging such a CT scan and Magnetic resonance imaging, are necesary for an effective diagnosis and monitoring of the disease. The treatment of choice is the surgical descompression with the use of antihelminthics in order to prevent the recurrence.
