RESUMO

BACKGROUND: Vessel perforation during thrombectomy is a severe complication and is hypothesized to be more frequent during medium vessel occlusion (MeVO) thrombectomy. The aim of this study was to compare the incidence and outcome of patients with perforation during MeVO and large vessel occlusion (LVO) thrombectomy and to report on the procedural steps that led to perforation. METHODS: In this multicenter retrospective cohort study, data of consecutive patients with vessel perforation during thrombectomy between January 1, 2015 and September 30, 2022 were collected. The primary outcomes were independent functional outcome (ie, modified Rankin Scale 0-2) and all-cause mortality at 90 days. Binomial test, chi-squared test and t-test for unpaired samples were used for statistical analysis. RESULTS: During 25 769 thrombectomies (5124 MeVO, 20 645 LVO) in 25 stroke centers, perforation occurred in 335 patients (1.3%; mean age 72 years, 62% female). Perforation occurred more often in MeVO thrombectomy (2.4%) than in LVO thrombectomy (1.0%, p<0.001). More MeVO than LVO patients with perforation achieved functional independence at 3 months (25.7% vs 10.9%, p=0.001). All-cause mortality did not differ between groups (overall 51.6%). Navigation beyond the occlusion and retraction of stent retriever/aspiration catheter were the two most common procedural steps that led to perforation. CONCLUSIONS: In our cohort, perforation was approximately twice as frequent in MeVO than in LVO thrombectomy. Efforts to optimize the procedure may focus on navigation beyond the occlusion site and retraction of stent retriever/aspiration catheter. Further research is necessary in order to identify thrombectomy candidates at high risk of intraprocedural perforation and to provide data on the effectiveness of endovascular countermeasures.

RESUMO

In certain cases, the closing force of a single vascular clip is not sufficient for complete aneurysmal occlusion, and the use of multiple clips, or clip stacking, is required. Many stacking techniques have been described in the literature, such as in tandem stacking and overstacking. However, these may not be feasible during procedures with limited exposure or narrow corridors. Clip reinforcement with a second high-pressure booster clip, also known as the piggyback technique, is an alternative for these cases along with anatomically complex aneurysms or aneurysms demonstrating atypical morphological features. Although this technique has been cited as a potential resource for certain aneurysms, descriptions of its characteristics and advantages are scarce. The purpose of this technical note was to discuss our experience with the piggyback clipping technique and use of a booster clip for a partially embolized and recanalized saccular posterior communicating artery aneurysm in a 50 year-old patient.

RESUMO

Tandem intracranial aneurysms (TandIAs) are rare but inherently complex, and special technical considerations are required for their surgical management. The present case highlights the key surgical aspects of two carotid-ophthalmic TandIAs incidentally found in a 60-year-old female. Both the aneurysms were superiorly projecting, regular in size, and involved the left ophthalmic segment of the internal carotid artery (ICA). The minimum distance between the necks was 3 mm. The patient underwent microsurgery because of the reported major complications rate of the endovascular treatment in the case of a very short minimum distance between the TandIAs. After cervical ICA exposure, both the aneurysms were excluded through a pterional approach. Intradural anterior clinoidectomy and unroofing of the optic canal allowed the mobilization of the left optic nerve. The more distal aneurysm was clipped before the opening of the distal dural ring of the ICA. The proximal aneurysm was clipped with two straight clips stacked perpendicular to the ICA. A small remnant was intentionally left to avoid the stenosis of the ophthalmic artery. Postoperative angiography showed the exclusion of both the aneurysms with a small dog-ear of the more proximal one. The patient was discharged neurologically intact and, after one year, the remnant remained stable. Microsurgical clipping is a definitive and durable treatment for carotid-ophthalmic TandIAs. In the case of a very short minimum distance between the aneurysms, the distal one should be clipped first to make the anterior clinoidectomy, opening of the distal dural ring of the ICA, and clipping of the more proximal aneurysm easier.

RESUMO

The syndrome of the trephined or craniectomized is commonly referred as neurological manifestations associated to skin flap depression and reversible after craneoplasty, which allows its differentiation from post-traumatic syndrome. We present the case of a male patient, 36 years old, with history of decompressive craniectomy. He evolved with sudden neurological worsening associated to syndrome of the trephined and recovery after craneoplasty. Physiopathology of the syndrome involves cerebrovascular, metabolic and cerebrospinal fluid hydrodynamic disturbances as well as parenchymal hyperdynamic mechanisms. Cranioplasty is the gold standard treatment. Still, studies with statistical power are needed to assess correct surgical timing.

RESUMO

El síndrome del trefinado o craniectomizado abarca manifestaciones neurológicas asociadas a la depresión del flap cutáneo y se distingue del síndrome postraumático por su reversibilidad con el tratamiento reparador del defecto craneano. El coma no es una forma habitual de presentación. Comunicamos un caso de presentación atípica en un hombre de 36 años de edad con antecedente de craniectomía descompresiva, que presentó un cuadro de deterioro neurológico profundo atribuible al síndrome del trefinado, el cual revirtió tras la craneoplastía. En la fisiopatología del síndrome intervienen trastornos cerebrovasculares, metabólicos, hidrodinámicos del líquido cefalorraquídeo e hiperdinamismo de las estructuras encefálicas. El gold standard terapéutico es la craneoplastía. Se requieren estudios de mayor peso estadístico para determinar el tiempo quirúrgico apropiado.

RESUMO

Introducción: Los gangliogliomas espinales representan casi el 14% de todos los tumores intramedulares, y su presentación es prácticamente infrecuente en pacientes mayores de 40 años. Descripción del caso: Se presenta el caso de un hombre de 45 años con 3 años de evolución de debilidad y parestesias en su mano izquierda. La resonancia magnética demostró una extensa lesión intramedular en la columna cervical. Se sometió a resección quirúrgica completa con diagnóstico histológico de ganglioglioma. A pesar de un empeoramiento transitorio del déficit neurológico en el posoperatorio, a los 90 días de seguimiento el paciente había recuperado su estatus neurológico preoperatorio. Conclusión: Aunque raro en adulto, esta entidad debe considerarse como diagnóstico diferencial en el diagnóstico de los tumores intramedulares. Se puede lograr una resección completa con buenos resultados funcionales y buen pronóstico oncológico.

RESUMO

Objetivo. Evaluamos la evolución de una población de 74 pacientes con diagnóstico de hemorragia subaracnoidea no traumática, en relación con la metodología de trabajo de un hospital público y la influencia de ciertos efectos operativos inherentes al sistema. Método. Los pacientes fueron internados en la Unidad de Terapia Intensiva (UTI) estudiados mediante tomografía axial computada (TC) y angiografía digital de 4 vasos, analizándose los tiempos de demora en la realización de los mismos. Consideramos la terapéutica al ingreso y el tratamiento quirúrgico (microcirugía o tratamiento endovascular). Evaluamos la morbimortalidad específica en función de la terapéutica implementada y la global de la población estudiada. Resultados. De los pacientes sometidos a microcirugía (36) fallecieron 8 (22e los casos que recibieron tratamiento endovascular (12) falleció un caso (8.33alidad global de la población estudiada fue de 24 pacientes (3). Conclusión. Consideramos que el diagnóstico y tratamiento de HSA no traumática en el hospital público enfrenta dificultades operativas para la adecuada implementación de una atención neuroquirúrgica de excelencia en tiempo oportuno.

RESUMO

Objetivo. Evaluar las complicaciones en la utilización de trasductores de presión intracraneana (PIC) K-30 subdurales (KS) y fibras ópticas intraparenquimatosas (FO). Método. En un estudio estadístico descriptivo y retrospectivo se revisaron las historias clínicas de los pacientes que ingresaron a Terapia Intensiva del Hospital "Juan A. Fernández" (junio 1993 - febrero 2003) y se requirieron monitoreo de PIC. Los datos fueron procesados con el programa STATA 6.0. Resultados. Se efectuaron 252 monitoreos en 191 pacientes: 71 monitores fueron FO y 181 fueron SK; 188 fueron catéteres únicos y 64 recambios. Los motivos de recambio fueron: arrancamiento, error de lectura, deterioro neurológico y colocación >5 días. El arrancamiento ocurrió en 13 casos (12 KS y 1 FO); error de lectura o falla técnica en 33 casos (20 KS y 13 FO); fístula de LCR en 9 casos (7 KS y 2FO). Sólo en un caso de los que presentaron fístula se constató cultivo de LCR positivo. (En 6 casos el recambio se debió a deterioro neurológico. Recambio por monitoreo >5 días ocurrió en 12). Período de monitorización: 1-15 días. La permanencia del monitor en pacientes con catéteres sin infección fue de 3.62 días y en pacientes con infección: 4.67 días. En 29 casos se comprobó infección (10FO y 19KS). No fue significativa la diferencia entre edad, sexo, Glasgow al ingreso y cirugía a cielo abierto cuando de lo relacionó con infección y tipo de monitor. Fue significativa la incidencia de infección en los pacientes reoperados. Conclusión. Técnicamente el monitoreo PIC con KS subdural demostró ser un método confiable. La incidencia de complicaciones, en particular la infecciosa, con sistema KS fue similar a las observadas con FO. Palabras clave: catéter subdural, complicaciones, infección, presión intracraniana


Objective: To evaluate the complications between to (sic) types of intracranial pressure monitoring devices: subdural K-30 (SK) and intraparenchymal fiber optic (FO). Method: In this descriptive retrospective study we reviewed the clinical records of those patients qho were admitted to the Intensive Care Unit of the Hospital "Juan A. Fernandez" (June 1993-February 2003) and requiered intracranial pressure monitoring. We processed the data with the STATA 6.0 programme. Results: We inserted 252 monitors in 191 patients: 71 FO and 181 SK; 188 were primary an 64 were secondary procedures. The causes of removal were: dislocation of the device, technical failure, neurological deteroration and premanence longer than 5 days. Dislocation occurred in 13 cases (12 SK, 1 FO), technical failure was observed in 33 cases (20 SK, 13 FO). We observed cerebrospinal fluid fistula (CSF) in 9 cases (7 SK, 2 FO). Only 1 case that presented with fistula had positive CSF culture with a non typified germen. In 6 cases the change of the catheter was due to neurological deteroration. Changing due to permanence longer than 5 days occurred in 12 cases. The period of monitorization was 1-15 days (median: 3 days). The permanence of the catheter in non infected patients was 3.62±3.22 days and on infected patients was 4.67±2.30 days. On 29 cases we observed infection, 10 FO and 19 SK (NS p). It was not significant the difference between age, sex, Glasgow and surgery when related to infection and type of device. It was significant the rate of infection in patients that had to be reoperated. Conclusion: From a technical point of view monitorization of the intracranial pressure using SK proved to be reliable. In our experience the rate of complications between the SK was similar to those observed with FO. Key words: intracranial pressure - complications - infection - subdural catheter.
