Thoracic splenosis: Case report of a symptomatic case / 中华创伤杂志(英文版)

Thoracic splenosis is the autotransplantation of splenic tissue in the left thoracic cavity as a result of a splenic injury. This rare pathology is usually asymptomatic and may be discovered on incidental imaging, but the diagnosis often requires invasive procedures such as surgery in order to eliminate a neoplasic origin. We report a rare symptomatic case of a 39-year-old man presenting with chest pain and multiple nodules revealed on a computed tomography scan. The patient underwent a surgical exploration and the pathological studies concluded to a thoracic splenosis. Indeed, the previous medical history of the patient revealed a left thoraco-abdominal traumatism during childhood. The aim of this paper is to emphasize that the diagnosis can now be performed using only imaging techniques such as technetium-99 sulfur colloid or labelled heat-denatured red blood cell scintigraphy to avoid unnecessary invasive procedures including thoracotomy.

Thoracic calcifications on magnetic resonance imaging: correlations with computed tomography / Calcificações torácicas na ressonância magnética: correlações com a tomografia computadorizada

ABSTRACT Objective: To identify the characteristics of thoracic calcifications on magnetic resonance (MR) imaging, as well as correlations between MR imaging and CT findings. Methods: This was a retrospective study including data on 62 patients undergoing CT scans and MR imaging of the chest at any of seven hospitals in the Brazilian states of Rio Grande do Sul, São Paulo, and Rio de Janeiro between March of 2014 and June of 2016 and presenting with calcifications on CT scans. T1- and T2-weighted MR images (T1- and T2-WIs) were semiquantitatively analyzed, and the lesion-to-muscle signal intensity ratio (LMSIR) was estimated. Differences between neoplastic and non-neoplastic lesions were analyzed. Results: Eighty-four calcified lesions were analyzed. Mean lesion density on CT was 367 ± 435 HU. Median LMSIRs on T1- and T2-WIs were 0.4 (interquartile range [IQR], 0.1-0.7) and 0.2 (IQR, 0.0-0.7), respectively. Most of the lesions were hypointense on T1- and T2-WIs (n = 52 [61.9%] and n = 39 [46.4%], respectively). In addition, 19 (22.6%) were undetectable on T1-WIs (LMSIR = 0) and 36 (42.9%) were undetectable on T2-WIs (LMSIR = 0). Finally, 15.5% were hyperintense on T1-WIs and 9.5% were hyperintense on T2-WIs. Median LMSIR was significantly higher for neoplastic lesions than for non-neoplastic lesions. There was a very weak and statistically insignificant negative correlation between lesion density on CT and the following variables: signal intensity on T1-WIs, LMSIR on T1-WIs, and signal intensity on T2-WIs (r = −0.13, p = 0.24; r = −0.18, p = 0.10; and r = −0.16, p = 0.16, respectively). Lesion density on CT was weakly but significantly correlated with LMSIR on T2-WIs (r = −0.29, p < 0.05). Conclusions: Thoracic calcifications have variable signal intensity on T1- and T2-weighted MR images, sometimes appearing hyperintense. Lesion density on CT appears to correlate negatively with lesion signal intensity on MR images.

RESUMO Objetivo: Identificar as características das calcificações torácicas na ressonância magnética (RM) e as correlações entre os achados de RM e TC. Métodos: Estudo retrospectivo no qual foram analisados dados referentes a 62 pacientes que foram submetidos a TC e RM de tórax em sete hospitais nos estados do Rio Grande do Sul, São Paulo e Rio de Janeiro entre março de 2014 e junho de 2016 e que apresentaram calcificações na TC. As imagens de RM ponderadas em T1 e T2 (doravante denominadas T1 e T2) foram analisadas semiquantitativamente, e a razão entre a intensidade do sinal da lesão e do músculo (LMSIR, do inglês lesion-to-muscle signal intensity ratio) foi estimada. Diferenças entre lesões neoplásicas e não neoplásicas foram analisadas. Resultados: Foram analisadas 84 lesões calcificadas. A média de densidade das lesões na TC foi de 367 ± 435 UH. A mediana da LMSIR foi de 0,4 [intervalo interquartil (II): 0,1-0,7] em T1 e 0,2 (II: 0,0-0,7) em T2. A maioria das lesões mostrou-se hipointensa em T1 e T2 [n = 52 (61,9%) e n = 39 (46,4%), respectivamente]. Além disso, 19 (22,6%) foram indetectáveis em T1 (LMSIR = 0) e 36 (42,9%) foram indetectáveis em T2 (LMSIR = 0). Finalmente, 15,5% mostraram-se hiperintensas em T1 e 9,5% mostraram-se hiperintensas em T2. A mediana da LMSIR foi significativamente maior nas lesões neoplásicas do que nas não neoplásicas. Houve uma correlação negativa muito fraca e estatisticamente insignificante entre a densidade das lesões na TC e as seguintes variáveis: intensidade do sinal em T1, LMSIR em T1 e intensidade do sinal em T2 (r = −0,13, p = 0,24; r = −0,18, p = 0,10 e r = −0,16, p = 0,16, respectivamente). A densidade das lesões na TC apresentou correlação fraca, porém significativa com a LMSIR em T2 (r = −0,29, p < 0,05). Conclusões: As calcificações torácicas apresentam intensidade de sinal variável em T1 e T2; em alguns casos, mostram-se hiperintensas. A densidade da lesão na TC aparentemente correlaciona-se negativamente com a intensidade do sinal da lesão na RM.

Appropriate angle and depth in thoracic transforaminal epidural block in Koreans

BACKGROUND: Selective transforaminal epidural block has come to the for as a targetspecific modality in the treatment and diagnosis of spinal pain. Thoracic transforaminal epidural block (TTFEB) has the associated risk of pneumothorax. This article describes a retrospective study conducted using computed tomography (CT) imaging to investigate the TTFEB angle and depth appropriate to minimize the risk of pneumothorax in Koreans. METHODS: The subjects of the present study were 100 randomly selected patients between 50 and 70 years of age found be free of thoracic disease according to chest CT performed in the present hospital. On the chest CT, the superior, middle, and inferior thoracic vertebrae were observed at the T2, T7, and T11 levels, respectively. RESULTS: The average distance and the needle insertion angle from the skin point at which the needle may be inserted without piercing the lung to the intervertebral foramen were 117.8 ± 12.1 mm and 58.1 ± 6.1° at the T2 level, 85.6 ± 10.0 mm and 61.7 ± 4.3° at the T7 level, and 94.3 ± 8.7 mm and 64.4 ± 7.0° at the T11 level, respectively. CONCLUSIONS: The needle insertion at the point further than 40 mm, on the upper, middle thorax, if the needle pass from the inner vertebral body to lamina, it could be safer. However, on the lower thorax, needle could pierce the lung though the needle start from the inner vertebral body. Thus, it can be safer if the needle pass toward the exterior margin of lamina.

Application of VSD in 6 Cases of Postoperative Infection -A Clinical Experience Sharing / 中国肺癌杂志

BACKGROUND@#Surgical site infection is one of the common postoperative complications of thoracic surgery, and its harm is related to infection degree and location. Light causes local pain, prolonged hospitalization and increased cost. Severe infection can lead to severe infection, even septic shock and life-threatening. Therefore, proper treatment of incision infection can help to promote recovery, reduce the burden of disease and lay a good foundation for further treatment. The traditional surgical treatment of wound infection includes thorough drainage, intensive dressing change and antibiotic use. There are many shortcomings such as long treatment process, ineffective treatment effect and so on. The experience of using vacuum sealing drainage (VSD) in 6 cases of postoperative infection patients in our department is summarized in order to improve the traditional treatment of postoperative infection in patients after thoracic surgery.@*METHODS@#The clinical data of patients with postoperative incision infection or fistula after thoracic surgery in our department were reviewed and summarized. 6 patients treated with VSD material for postoperative infection. The process and final clinical results of them were summarized and discussed.@*RESULTS@#In this study, fever and wound exudation disappeared within 6 h-10 h after VSD use, 5 cases of wound infection were obviously improved, the secretion disappeared and the granulation tissue grew well at the cutting edge of the operation, the second stage operation was performed to close the chest and skin. One patient was seriously infected, and the secretion was still more after VSD removal, reposition VSD device next time, the VSD device was removed 7 d later. The wound infection were obviously improved, the secretion disappeared and the granulation tissue grew well, close the chest and skin second stage. In all 6 patients, the symptoms were relieved, the symptoms improved and the surgical incision healed well. In 2 patients with esophageal cancer, the average operation time was 427.5 min, the average hospitalization time was 40 d, the average number of times of dressing change was 8.5, the average total cost during hospitalization was 111,893.47 yuan patients with chronic empyema, the average operation time was 192.5 min. The average hospital stay was 27.75 days, the average number of times of dressing change was 5.5, and the average total expenditure during hospitalization was 48,237.71 yuan.@*CONCLUSIONS@#VSD has a good effect on the treatment of postoperative incision infection patients in thoracic surgery. It can reduce the pain and burden of patients and ensure the quality of life of postoperative infected patients.

Endometriosis diafragmática: a propósito de un caso / Diaphragmatic endometriosis: about a case

ANTECEDENTES: La endometriosis afecta entre 5 al 15% de las mujeres en edad reproductiva. La presentación torácica es una entidad de baja frecuencia (menos del 1% de todos los casos de endometriosis), y puede localizarse en vía aérea, parénquima, pleuras o diafragma. Sus manifestaciones clínicas habitualmente se presentan dentro de las primeras 72 horas del inicio de la menstruación y consisten en dolor torácico, neumotórax o hemoptisis. El mejor manejo consiste en supresión hormonal y manejo quirúrgico en casos refractarios. OBJETIVOS: Describir un caso de endometriosis diafragmática tratada satisfactoriamente por videotoracoscopia. CASO CLÍNICO: Mujer de 27 años, con antecedentes de endometriosis ovárica operada con electrofulguración dos años previo. Consulta por omalgia derecha y dado antecedentes de endometriosis pélvica, se solicita TAC torácico, que informa formación sólida, ovoídea, de 30 mm x 13 mm, que capta contraste en forma parcial ubicado en la región subdifragmática derecha. Se interpreta imagen como posible foco de endometriosis, se complementa con RNM que es concordante con el diagnóstico. Se realiza videotoracoscopia derecha con resección diafragmática y reparación primaria. Anatomía patológica informa focos de endometriosis con márgenes negativos. Se retira la pleurostomía a las 48 horas, siendo dada de alta a los tres días. A un año de seguimiento, está asintomatica y sin evidencia de recidiva. CONCLUSIÓN: A pesar de su baja frecuencia, la endometriosis torácica representa un importante compromiso de la calidad de vida. Casos con complicaciones torácicas, con regular o deficiente respuesta a terapia hormonal, se benefician de resolución quirúrgica por vía mínimamente invasiva.

BACKGROUND: Endometriosis affects between 5 to 15% of women of reproductive age. Thoracic presentation entity is infrequent (less than 1% of all cases of endometriosis) and may be located in airway parenchyma, pleura or diaphragm. Its clinical manifestations usually occur within the first 72 hours of onset of menstruation and include chest pain, pneumothorax or hemoptysis. Better management consists of hormonal suppression and surgical management in refractory cases. OBJECTIVE: To describe a case of diaphragmatic endometriosis, successfully treated by video-assisted thoracoscopic surgery (VATS). CASE REPORT: Woman of 27 years old, with a history of ovarian endometriosis operated by electrofulguration two years before. She present right omalgia and a history of pelvic endometriosis. Chest CT report a solid, ovoid formation, 30 mm x 13 mm, which captures contrast partially, located in the right sub diaphragmatic region. Image is interpreted as a possible focus of endometriosis, it is complemented by RNM that is consistent with the diagnosis. It is performed VATS right with diaphragmatic resection and primary repair. Pathology reports endometriosis with negative margins. The pleurostomy is removed after 48 hours, she was discharged after three days. A one year follow up, it is asymptomatic and without evidence of recurrence. CONCLUSION: Despite its low frequency, the thoracic endometriosis represents an important commitment to the quality of life. Cases with chest complications, and with fair or poor response to hormone therapy, benefit with minimally invasive surgical resolution.

Treatment of thoracic hemorrhage due to rupture of traumatic mediastinal hematoma / 中华创伤杂志(英文版)

Patients in traffic accidents are usually presented with pain and bleeding due to fractures or soft tissue injury. On some occasions, more severe complications may be triggered by the trauma. A review of the published English language literature reveals no survival case once the traumatic mediastinal hematoma is ruptured. In our case, a 54-year-old man suffering motorcycle accident was admitted to emergency department. Computed tomography scan revealed subdural hematoma combined with posterior mediastinal hematoma. The patient was saved and discharged with a satisfactory outcome. Here we hope to share our treatment experience in dealing with the patient with severe multiple trauma.

Lung Ultrasound in Critically Ill Patients / 대한구급학회지

Lung ultrasound (LUS) is an emerging tool for intensivists to diagnose and monitor thoracic diseases of critically ill patients. It is easily applied at the bedside in real time and is free of radiation hazards. In the intensive care units (ICUs) lung ultrasound can be used to diagnose pneumothorax and interstitial syndrome. It can also be used to monitor changes in the lung. However, the major limitations of LUS is that it is highly operator dependent and cannot be applied in patients with thoracic dressings, subcutaenous emphysema or pleural calcifications. This article reviews the basic principles of lung ultrasound and discusses how it can be used in ICUs.

Se revisa en una muestra pictográfica las principales indicaciones y utilidad de esta técnica.

A Study into the Potential for Safe Application of Single-Incision Thoracoscopic Surgery in Various Thoracic Diseases

OBJECTIVE: Single-incision thoracoscopic surgery (SITS) is being applied to various thoracic diseases because it produces a smaller surgical scar, and is associated with less pain and loss of sensation compared to the traditional 3-port video-assisted thoracoscopic surgery (VATS). In our previous study, we showed that SITS can be used as a first-line surgical method to treat primary spontaneous pneumothorax. Therefore in this study, we looked into whether SITS can be safely and conveniently applied to other various thoracic diseases. METHODS: The subjects for this study those patients who underwent SITS at this hospital for thoracic diseases, who were admitted to this hospital between December 2013 and February 2015. RESULTS: In this study, SITS was attempted in 50 patients with various thoracic diseases. In 46 cases, SITS was successfully performed. However, in the remaining 4 cases were converted to 2-port or 3-port VATS (8%, 4/50). The reasons for conversion to VATS was due to difficulty in approaching the lesion (n=3) and severe pleural adhesion (n=1). CONCLUSION: We found that SITS is a relatively easy and safe procedure that can be applied to various thoracic diseases. However, the operation may be difficult to perform depending on the location of the lesions or the extent of pleural adhesions. Therefore we recommend SITS in conditions where the lesion is mainly in the upper lobe, such as spontaneous pneumothorax, and in patients with minimal level of pleural adhesions.
