Hemangioma hepático gigante único: serie de casos con seguimiento de pacientes tratados quirúrgicamente / Single giant liver hemangioma: case series with follow-up of patients treated surgically

El tratamiento del hemangioma hepático gigante (HHG), sigue siendo motivo de controversia. El objetivo de este estudio fue reportar los resultados de pacientes con HHG resecados quirúrgicamente en términos de morbilidad postoperatoria (MPO). Serie de casos con seguimiento. Se incluyeron pacientes con HHG, sometidos a cirugía de forma consecutiva, en Clínica RedSalud Mayor, entre 2011 y 2020. La variable resultado fue MPO. Otras variables de interés fueron: tiempo quirúrgico, estancia hospitalaria y mortalidad. Las pacientes fueron seguidas de forma clínica. Se utilizó estadística descriptiva, con medidas de tendencia central y dispersión. Se intervinieron 5 pacientes, con una mediana de edad de 38 años. La medianas del tiempo quirúrgico y estancia hospitalaria; fueron 75 min y 4 días respectivamente. La MPO fue 20 % (1 caso de seroma). Con una mediana de seguimiento de 41 meses, los pacientes se encuentran asintomáticos y no se ha verificado morbilidad alejada. La resección quirúrgica de un HHG se puede realizar con escasa morbilidad, tanto en términos numéricos como de gravedad de la complicación observada.

SUMMARY: Treatment of giant hepatic hemangioma (GHH) remains controversial. The aim of this study was to report the outcomes of surgically resected GHH patients in terms of postoperative morbidity (POM). Case series with follow-up. Patients with GHH who underwent surgery consecutively at the RedSalud Mayor Clinic between 2011 and 2020 were included. The outcome variable was POM. Other variables of interest were surgical time, hospital stay and mortality. The patients were followed up clinically. Descriptive statistics were used, with measures of central tendency and dispersion. Five patients underwent surgery, with a median age of 38 years. The median surgical time and hospital stay; were 75 min and 4 days respectively. The MPO was 20 % (1 case of seroma). With a median follow-up of 41 months, the patients are asymptomatic, and no distant morbidity has been verified. Surgical resection of GHH can be performed with low morbidity, both in terms of numbers and the severity of the complication observed.

Scanning electron microscopy of dermatofibroma

Abstract: Dermatofibroma is a proliferation of spindle cells located in the dermis. We used scanning electron microscopy to examine two histologically confirmed lesions and observed preserved collagen bundles in the perilesional area. In the lesional area, the collagen was denser, without formation of bundles. Higher magnification showed collagen with mesh-like appearance similar to stretched tufts of cotton. Very high magnification evidenced the tufts of cotton and spindle cells measuring 2 to 12 microns.

Anomalias venosas nos cavernomas / Venous anomalies in cavernomas

As anomalias do desenvolvimento venoso (DVA) são as malformações vasculares cerebrais mais frequentes, tendo geralmente um curso benigno, e podem estar acompanhando os cavernomas. Atualmente, são mais diagnosticadas por causa dos métodos de diagnósticos por imagem que existem, como a tomografia computadorizada e, sobretudo, a ressonância magnética nuclear. Este artigo revisa as DAV em geral e as relacionadas com os cavernomas. Os artigos foram buscados na base de dados PubMed, em publicações desde 1995 a junho de 2012, usando como filtros as expressões ?anomalias do desenvolvimento venoso e malformações cavernosas? e ?anomalias venosas cerebrais e malformações cavernosas?; a pesquisa foi limitada a artigos em idioma inglês e relacionados a humanos. As sessões de referência de artigos e revisões recentes foram revisadas e os artigos pertinentes foram recuperados no formato resumo; os manuscritos em texto completo foram obtidos subsequentemente para todos os artigos originais aplicados à revisão em curso...

Treatment of thoracolumbar tumors with total en bloc spondylectomy and the results of spinal stability reconstruction / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To investigate the therapeutic effect of total en bloc spondylectomy (TES) for thoracolumbar tumors and the results of spinal stability reconstruction.</p><p><b>METHODS</b>From January 2007 to June 2011 there were 18 patients with thoracolumbar tumors distributed in the thoracic vertebrae (n = 10) and lumbar vertebrae (n = 8). There were 7 haemangiomas, 5 giant cell tumors of bone, 1 malignant schwannoma, 1 solitary plasmocytoma, 1 neuroblastoma, 1 osteoblastoma, 1 metastatic malignant fibrous histiocytoma, and 1 metastasis of breast cancer. All the 18 patients were treated with improved TES under electrophysiological monitoring of spinal cord. Four patients were treated through one-stage combined anteroposterior approach and 14 patients through one-stage posterior approach. The anterior reconstructions included titanium mesh cages filled with bone or bone cement in 15 cases, titanium mesh cage with strengthened rings in 2 cases and artificial vertebral body replacement in 1 case. The posterior reconstruction included multiple segmental fixation with pedicle screw-rod system in 15 cases and short segmental fixation in 3 cases. Massive bone auto-graft was employed in 13 cases and fragmental bone graft in 5 cases.</p><p><b>RESULTS</b>The total en bloc spondylectomy was performed successfully in 15 patients and unsuccessful in 3 whose spinal tumors were resected by piecemeal technique. In 15 patients with successfully performed TES, the duration of surgery was from 340 to 610 min (average, 450.7 min), the blood loss was from 3000 to 10 200 ml (average, 4850 ml), and the intraoperative blood transfusion was from 2800 to 9600 ml (average, 4200 ml). The operation-related complications comprised hemopneumothorax, intercostal nerve pain, stress ulcer and bleeding, and so on. One year after operation, the patients with neurological dysfunction recovered from grade A to grade D in one patient, and to grade E in the other 14 cases. The average visual analog scale (VAS) scores was 0.5. One patient with plasmacytoma and another one with L5 metastatic tumor suffered progression of the disease and were living with the diseases. The patient with metastatic malignant fibrous histiocytoma died of local recurrence and lung metastasis 16 months postoperatively. One patient with L4 neuroblastoma died of other reason and all the rest were free from relapse. The Cobb angle of upper and lower vertebral body adjacent to the involved vertebrae in sagittal plane was from -26.7° to 12.0° (average, -2.57°) just postoperatively and from -17.5° to 57.2° (average, 11.5°) at the last follow-up or before reoperation. There were 2 patients with screw-rod breakdown and 2 patients with internal fixation loosening. The measurement of titanium mesh cage subsided into adjacent vertebral bodies was average 7.5 mm. The revision surgery was performed in 3 patients, through combined anteroposterior approach in 2 and only posterior approach in 1 patient.</p><p><b>CONCLUSIONS</b>TES significantly increases the therapeutic effect of spinal tumors, although accompanied with high difficulty and massive bleeding. In spinal stability reconstruction after total spondylectomy, it should be emphasized that posterior long segment fixation with pedicle screw-rod system, massive bone bridging graft and the application of thoracolumbosacral orthosis can achieve short-term firm fixation and long-term fusion-stabilization.</p>

One-stage total en bloc spondylectomy and reconstruction via a single posterior approach for thoracic vertebral symptomatic hemangioma associated with spinal cord dysfunction / 中华外科杂志

<p><b>OBJECTIVES</b>To investigate the surgical results of one-stage total en bloc spondylectomy (TES) and reconstruction via a single posterior approach for thoracic symptomatic vertebral hemangioma associated with spinal cord dysfunction and evaluate its curative effect.</p><p><b>METHODS</b>A total of 9 patients treated with one-stage TES (7 cases) and total vertebrectomy (2 cases) by posterior approach from March 2006 to January 2010 were retrospectively reviewed. The cases included 2 males and 7 females with a median age of 33.6 years (range 14 to 77 years), and with 1 case of Grade A, 3 cases of Grade B, 3 cases of Grade C, 2 cases of Grade D according to Frankel grade system. All patients suffered from moderate to severe pain and neurological deficit with an average symptom duration of 14.4 months (range 3 - 24 months) MRI revealed severe spinal cord compression. The spinal reconstruction was obtained by titanium mesh filled with autograft and posterior internal fixation with rod-screw system.</p><p><b>RESULTS</b>The operation time was 210 minutes on average (180 - 270 minutes) and the average blood loss was 1800 ml (1000 - 5000 ml). The follow-up period lasted from 18 months to 5 years. All cases with preoperative pain relieved after operation. The visual analogue scale pain scores decreased to 1.1 from 8.3 at 3 months after surgery. No disruption of dural mater, cerebrospinal fluid leakage, iatrogenic spinal cord injury and major vessel damage occurred. Up to now, there was no local recurrence in all cases. Significant neurological function improvement was achieved in all patients with one to three grades in Frankel grade system. Fusion of the autograft was well achieved and no internal fixation failure in all patients.</p><p><b>CONCLUSIONS</b>One-stage TES and spine reconstruction by a single posterior approach is feasible, safe and effective to this disease. It is favourable in decreasing the hemangioma recurrence and improvement of the neurological function.</p>

Reconstrucción de la pared torácica mediante prótesis sintética moldeada durante el acto operatorio / Abdominal wall of the reconstruction intervening synthetical prothesis during surgery acto

La reparación de la pared torácica consecutiva a resecciones extensas de esqueleto debidas por lo general a neoplasias, debe ser cuidadosamente efectuada con la finalidad de restaurar la rigidez y la estabilidad del torax, previniendo trastornos ventilatorios que de otro modo inevitablemente ocurrirían. A 4 pacientes que habían sido sometidos a la exéresis parcial de varias costillas, 3 de ellos con parte de esternón, se les colocó una prótesis fabricada con malla de marlex y metilmetacrilato. Para confeccionar esa prótesis fue utilizado un molde o matriz de aluminio con la forma y el tamaño de una sección de la pieza operatoria; por consiguiente aquélla se adaptó con bastante precisión a la brecha parietal. Se describe el procedimiento. El resultado funcional fue muy satisfactorio.
