Mechanical thrombectomy beyond 6 hours in acute ischaemic stroke with large vessel occlusion in the carotid artery territory: experience at a tertiary hospital.

INTRODUCTION: Thrombectomy in the carotid artery territory was recently shown to be effective up to 24 hours after symptoms onset. METHODS: We conducted a retrospective review of a prospective registry of patients treated at our stroke reference centre between November 2016 and April 2019 in order to assess the safety and effectiveness of mechanical thrombectomy performed beyond 6 hours after symptoms onset in patients with acute ischaemic stroke and large vessel occlusion in the carotid artery territory. RESULTS: Data were gathered from 59 patients (55.9% women; median age, 71 years). In 33 cases, stroke was detected upon awakening; 57.6% of patients were transferred from another hospital. Median baseline NIHSS score was 16, and median ASPECTS score was 8, with 94.9% of patients presenting > 50% of salvageable tissue. Satisfactory recanalisation was achieved in 88.1% of patients, beyond 24 hours after onset in 5 cases. At 90 days of follow-up, 67.8% were functionally independent; those who were not were older and presented higher prevalence of atrial fibrillation, greater puncture-to-recanalisation time, and higher NIHSS scores, both at baseline and at discharge. CONCLUSION: In our experience, mechanical thrombectomy beyond 6 hours was associated with good 90-day functional outcomes. Age, NIHSS score, puncture-to-recanalisation time, and presence of atrial fibrillation affected functional prognosis. The efficacy of the treatment beyond 24 hours after onset merits study.

A collaborative system for endovascular treatment of acute ischaemic stroke: the Madrid Stroke Network experience.

BACKGROUND AND PURPOSE: The complexity and expense of endovascular treatment (EVT) for acute ischaemic stroke (AIS) can present difficulties in bringing this approach closer to the patients. A collaborative node was implemented involving three stroke centres (SCs) within the Madrid Stroke Network to provide round-the-clock access to EVT for AIS. METHODS: A weekly schedule was established to ensure that at least one SC was 'on-call' to provide EVT for all those with moderate to severe AIS due to large vessel occlusion, >4.5 h from symptom onset, or within this time-window but with contraindication to, or failure of, systemic thrombolysis. The time-window for treatment was 8 h for anterior circulation stroke and <24 h in posterior stroke. Outcomes measured were re-canalization rates, modified Rankin Scale (mRS) score at 3 months, mortality and symptomatic intra-cranial haemorrhage (SICH). RESULTS: Over a 2-year period (2012-2013), 303 candidate patients with AIS were considered for EVT as per protocol, and 196 (65%) received treatment. Reasons for non-treatment were significant improvement (14%), spontaneous re-canalization (26%), clinical worsening (9%) or radiological criteria of established infarction (31%). Re-canalization rate amongst treated patients was 80%. Median delay from symptom onset to re-canalization was 323 min (p25; p75 percentiles 255; 430). Mortality was 11%; independence (mRS 0-2) was 58%; SICH was 3%. CONCLUSIONS: Implementation of a collaborative network to provide EVT for AIS is feasible and effective. Results are good in terms of re-canalization rates and clinical outcomes.

Diagnóstico y tratamiento de las lesiones benignas de la mama en el embarazo / Diagnosis and treatment of benign breast lesions during pregnancy

Objetivo. Estudiar retrospectivamente el diagnóstico y tratamiento de la patología benigna de la mama durante el embarazo y puerperio realizado en nuestra Unidad. Revisamos la literatura existente al respecto.Materiales y métodos. De enero de 2001 a marzo de 2005 diagnosticamos un total de 91 mujeres (gestantes o puérperas) con patología mamaria benigna manifestada como nódulo palpable o clínica inflamatoria, con un rango de edad de 23-36. En todos los casos se realizóecografía y citología diagnóstica, siendo necesaria la realización de biopsia percutánea con aguja gruesa en tres ocasiones. En el caso de los abscesos se procedió también a su drenaje. Todo se realizó tras la obtención del correspondiente consentimiento informado.Resultados. En 28 casos (30%) se detectaron tumoraciones: fibroadenomas (12), adenomas de lactancia (9), galactoceles (5) y papilomas (2). El tratamiento fue conservador con seguimiento ecográfico, salvo en un caso que precisó tratamiento quirúrgico en el tercer trimestre. En 63 ocasiones (70%) la patología fue inflamatoria, evidenciándose abscesos en 24 (38%), de los cuales se drenaron con aguja fina 16 y concatéter pig-tail 3, según protocolo, atendiendo a su tamaño (menor o mayor de 3 cm). En 5 casos se realizó drenaje quirúrgico.Conclusiones. La patología benigna más frecuente durante la gestación es la inflamatoria, que se maneja satisfactoriamente con antibióticos y drenaje percutáneo, siendo el resultado estético mejor. La ecografía es la técnica diagnóstica de elección junto con la citología y sólo en casos dudosos realizaremos biopsia percutánea por el riesgo de fístulas

Objectives. To retrospectively study the diagnosis and treatment of benign breast disease during pregnancy and breastfeeding at our department. To review the relevant literature.Materials and methods. From January 2001 to March 2005, a total of 91 pregnant or breastfeeding women (age range: 23-36 years) were diagnosed with benign breast pathology. All patients presented with palpable nodules or inflammatory symptoms. Ultrasound-guided fineneedle cytology was performed in all cases and percutaneous core biopsy was considered necessary in three cases. Abscesses were drained when present. Patients provided their informed consent before all procedures.Results. Tumors were detected in 28 cases (30%): fibroadenomas (n = 12), lactating adenomas (n = 9), galactoceles (n = 5), and papillomas (n = 2). Conservative treatment with ultrasound follow-up was employed in all cases except one, which required surgical treatment in the third trimester. On 63 occasions (70%), the pathology was inflammatory, including abscesses in 24 cases (38%); abscesses were drained using fine-needle aspiration (n = 16) or pig-tail catheter (n = 3), according to protocol, depending on the size of the abscess (less than or greater than 3 cm). In 5 cases the abscesses were drained surgically.Conclusions. The most common benign breast pathology during pregnancy is inflammatory and is satisfactorily managed with antibiotics and percutaneous drainage with good esthetic results. Ultrasound is the diagnostic technique of choice, together with cytology; percutaneous biopsy is only performed in uncertain cases to minimize the risk of fistulas. Management of tumors after histological confirmation should be conservative with close follow-up. These tumors cause no problems for the child, the mother, or breastfeeding
