Congenital horner syndrome: a rare though significant complication of subclavian flap aortoplasty

Horner syndrome due to right subclavian artery dissection: Case report

This is a novel case of spontaneous subclavian artery dissection presenting with an asymptomatic right Horner Syndrome, highlighting both the importance of carefully evaluating the pupils on comprehensive exam, and also the subclavian arteries when assessing for the cause of Horner Syndrome. This original case serves as a caution for practitioners not to overlook the subclavian arteries in the search for the cause of Horner Syndrome. While rare, spontaneous subclavian artery dissection can occur, and carries a risk of morbidity and mortality that must be mitigated. We present a case of asymptomatic, atraumatic right Horner Syndrome where a spontaneous right subclavian artery dissection was found to be the source. It was managed with aspirin therapy and the patient has not suffered any subsequent cardiovascular events related to the dissection. Careful angiographic evaluation of the subclavian arteries should be included in the workup for Horner Syndrome to assess for subclavian artery dissection.

Imaging of Horner syndrome in pediatrics: association with neuroblastoma

Neuroblastoma is the most common neoplasm associated with pediatric Horner syndrome. The laboratory and imaging evaluation of isolated pediatric Horner syndrome is controversial. We review the literature published in the last several decades and present the rationale for the imaging work-up in this patient cohort.

Horner's syndrome after paediatric cardiac surgery: case report and review of the literature

Iatrogenic Horner's syndrome is a rare complication that can occur after trauma, cervical central line insertion, chest tube insertion, and rarely following adult thoracic and neck surgery, especially in high risk patients with hypertension and diabetes. The majority of cases reported in the literature describe non-iatrogenic Horner's syndrome in adults as an unusual presentation for cervical tumours or apical lung carcinoma. In children, there are some reports describing acquired Horner's syndrome following trauma or invasive intervention near the cervical-thoracic area. Less has been written about the incidence of Horner's syndrome following paediatric cardiac surgery.

Síndrome de Claude Bernard-Horner associada ao empiema pleural

A síndrome de Claude Bernard-Horner apresenta várias etiologias, ocorre por interrupção do estímulo nervoso em qualquer ponto do trajeto do nervo e pode ser intra ou extratorácica. É relatado um caso dessa síndrome causado por empiema pleural septado, localizado em região paravertebral, no terço superior do hemitórax direito. O paciente foi submetido à toracotomia para drenagem da cavidade pleural. A evolução foi satisfatória, com regressão do quadro infeccioso, expansão pulmonar e remissão da síndrome.
