RESUMO

Introducción: El hematoma de la vaina de los rectos es poco frecuente. En este reporte se presenta un caso clínico de este cuadro en un paciente con neumonía por COVID-19 y leucemia mieloide crónica, junto con una revisión de literatura. Caso Clínico: Paciente masculino de 55 años, hospitalizado por neumonía por COVID-19 y leucemia mieloide crónica, presenta taquicardia, hipotensión y aumento de volumen abdominal asimétrico. En la tomografía computarizada se evidencia un hematoma de la vaina de los rectos. Se realiza drenaje quirúrgico y control del sangrado. No presentó complicaciones postoperatorias ni necesidad de reoperación. Discusión: Las complicaciones hemorrágicas en pacientes con COVID-19 están poco descritas. El sangrado es una posible complicación en pacientes con leucemia mieloide crónica. Es relevante tener en cuenta el hematoma de la vaina de los rectos en pacientes con COVID-19 y/o leucemia mieloide crónica que presenten aumento de volumen abdominal, para un manejo precoz por un equipo multidisciplinario. Conclusión: La vigilancia activa y el alto índice de sospecha son clave para identificar posibles complicaciones hemorrágicas en pacientes con COVID-19 y/o leucemia mieloide crónica.


Introduction: Rectus sheath hematoma is a rare entity. This report presents a clinical case of a rectus sheath hematoma in a patient with COVID-19 pneumonia and chronic myeloid leukemia, along with a review of the literature. Case Report: A 55-year-old male patient, hospitalized for COVID-19 pneumonia and chronic myeloid leukemia, presents with tachycardia and hypotension. Computed tomography shows a rectus sheath hematoma. Surgical management was performed to control bleeding and drainage of the hematoma. There were no postoperative complications or need for reoperation. Discussion: Hemorrhagic complications in patients with COVID-19 are seldomly reported. Bleeding is a possible complication in patients with chronic myeloid leukemia. It is important to take into account rectus sheath hematoma in patients with COVID-19 and/or chronic myeloid leukemia who present with abdominal pain, for early management by a multidisciplinary team. Conclusion: Active surveillance and a high index of suspicion are key to identifying potential bleeding complications in patients with COVID-19 and/or chronic myeloid leukemia.

RESUMO

Corona mortis es una variación anatómica referida a la anastomosis de los vasos iliacos externos e internos, mediante vasos que se arquean por encima y por detrás del ramo superior del pubis. En caso de resultar lesionados iatrogénicamente, se pueden presentar hemorragias de difícil manejo. El objetivo del estudio fue caracterizar los vasos obturatrices en una muestra cadavérica de la población colombiana, para determinar su morfometría y la frecuencia con que se presentan los diferentes patrones venosos y arteriales. Se estudiaron hemipelvis de 14 cadáveres, pertenecientes al anfiteatro del Departamento de Morfología de la Universidad del Valle en Cali, Colombia. Tras acceder a la cavidad pélvica y completar la disección de todos los vasos que se relacionaban con el canal obturador y la cara pélvica del ramo superior del pubis, se determinaron sus características morfológicas y sus dimensiones. Las variaciones arteriales, corona mortis y arteria obturatriz aberrante, se presentaron en el 35,7% de las hemipelvis y las variaciones venosas en el 82,1%. La arteria corona mortis sólo se presentó en el 3,6% de las hemipelvis y el 32,1% presentaron arteria obturatriz aberrante. La moda de las frecuencias absolutas de los patrones venosos fue la vena corona mortis que se presentó en el 75,0% de las hemipelvis. El conocimiento de los patrones arteriales y venosos de los vasos obturatrices y de sus variaciones anatómicas para la población colombiana es indispensable para evitar lesionarlos durante procedimientos clínico - quirúrgicos que comprometan el anillo pélvico anterior y la región inguinal.


The corona mortis is an anatomical variation related to the anastomosis between the internal and external iliac blood vessels, through certain arteries and veins that form arches above and behind the superior pubic ramous. Serious hemorrhages can result from iatrogenic injury of these vessels. The study objective was to characterize the obturator vessels in a sample of Colombian cadavers, to determine their morphometric features and the frequencies in which the arterial and venous patterns are present. Hemipelvises of 14 cadavers from the dissection room of the Department of Morphology at the Universidad del Valle, in Cali, Colombia, were taken as sample. Once the dissection of the vessels related with the obturator canal and the pelvic surface of the superior pubic ramous was completed, their morphological features were determined and measurements were taken of their diameters and lengths. The arterial variations, corona mortis and aberrant obturator artery, were present in 35.7% of the hemipelvises and the venous variations in 82.1%. The corona mortis artery was only present in 3.6% of the hemipelvises and 32.1% presented an aberrant obturator artery. The mode of the absolute frequencies of the venous patterns was the corona mortis vein, present in 75.0% of the hemipelvises. The knowledge of the arterial and venous patterns of the obturator vessels and their anatomical variations for the Colombian population is very important in order to avoid causing any injury to them in the course of clinical and surgical procedures that have to do with the anterior pelvic ring and the inguinal region.

RESUMO

PURPOSE: To describe the anatomical variations of superficial inferior epigastric artery (SIEA) flap as a muscle-sparing flap. METHODS: A series of 40 dissections were performed on 20 preserved or fresh male cadavers. The site origin and drainage of vessels, caliber, length, and correlation between diameter and length of pedicle were identified. RESULTS: The SIEA and SIEV were identified at inguinal ligament level in 38 (95 percent) and 40 (100 percent) dissections, respectively. The SIEA originated directly from a common femoral artery 22 (57.9 percent) or a common trunk with other arteries. The SIEA was found within 1 cm of the midpoint of the inguinal ligament in 33 of 38 cases. The meanSD length of SIEA was 3.041.73 (0.5-7) cm. The meanSD caliber of SIEA was 1.450.35 (0.7-2.1) mm. The length of SIEV ranged from 2.2 to 12 cm with a meanSD of 5.452.08 cm. The caliber of SIEV ranged from 1.6 to 4 mm with a meanSD of 2.140.45 mm. The length of SIEA correlated with caliber of arterial pedicle (p<0.001 and correlation coefficient = 0.517). CONCLUSION: The inferior epigastric artery flap can be applied to microsurgical flap transfer, potentially in breast reconstruction, hemifacial atrophy, phalloplasty, or when extremely large amounts of skin coverage are required.


OBJETIVO: Descrever as variações anatômicas do retalho muscular com artéria epigástrica superficial. MÉTODOS: Foram realizadas uma série de 40 dissecções em cadáveres do gênero masculino, preservados ou recentes, Foram identificados o local de origem e drenagem dos vasos: calibre, comprimento e correlação entre diâmetro e comprimento do pedículo. RESULTADOS: As artérias e veias epigástricas superficiais foram identificadas no nível do ligamento inguinal respectivamente em 38 (95 por cento) e 40 (100 por cento) das dissecções. A artéria epigástrica superficial originava diretamente da artéria femoral em 22 (57,9 por cento) ou de um tronco comum com outras artérias. A artéria foi encontrada em um cm do ponto médio do ligamento inguinal em 33 de 38 casos. A média do comprimento da artéria epigástrica superficial foi de 3.04 1.73 (0,5-7) cm. A média do calibre da artéria foi 1.45 0.35 (0.7-2.1). O comprimento da veia epigástrica superficial foi de 2.2 a 12 cm com média de 5.452.08 cm. O calibre da veia era de 1.6 a 4 mm com média de 2.140.45 mm. O comprimento da artéria epigástrica superficial foi correlacionado com o calibre do pedículo arterial. CONCLUSÃO: O retalho com a artéria epigástrica superficial pode ser aplicado em microcirurgia de retalhos, potencialmente em reconstrução mamária, atrofia hemifacial, faloplastia ou quando se faz necessário aplicar em perdas acentuadas de pele.

RESUMO

El conocimiento de la vascularización de la pared anterior del abdomen es un importante instrumento para la realización de incisiones y punciones abdominales, contribuyendo a evitar algunas complicaciones reurrentes de este procedimiento. Con el propósito de estudiar la emergencia y el trayecto de las arterias epigástricas superiores, fueron disecados 32 cadáveres adultos, del sexo masculino, no fijados, blancos y no blancos, con edades entre 18 y 65 años. Se observó el trayecto de las arterias epigástricas superiores, su emergencia y su forma de distribución. Las arterias epigástricas superiores emergieron por atrás del 7 cartílago costal en todos los casos. En el 75% de los casos las arterias epigástricas se presentaron como un tronco único y en 15 casos (23,44%) bifurcadas, siendo 11 a la derecha y 4 a la izquierda y en 1 caso (1,56%) a la izquierda. En este último, caso dio origen a tres ramos principales. Cuando era un tronco único, su trayecto fue descendente de medial para lateral en relación al margen lateral del músculo recto del abdomen. Cuando era bifurcada, sus ramos se separaron uno del otro luego de su emergencia, volviendo a convergir próximo a la cicatriz umbilical.


The knowledge of the vascularization of the anterior abdominal wall is very important on the incisions and abdominal punctures, contributing to avoid the injuries of this vessels during this procedures. With the goal to study the emergency and the trajectory of the superior epigastric arteries, 32 adult not preserved cadavers, of the masculine sex, white and not white, with age between 18 and 65 years were studied. The trajectory of the superior epigastric arteries, your emergency and distribution form were observed. The superior epigástric arteries emerged behind to 7th costal cartilage in all the cases. In 75% of the cases they appeared like an only trunk and in 15 cases (23,44%) they appeared forked, being 11 to the right and 04 to the left and in 01 case (1,56%) to the left, it'd origin three main branches. When in an only trunk, your trajectory went descending of medial for lateral in relationship to the lateral margin of the rectus abdominal muscle. When forked, your branches separated one of the other immediatelly after your emergency, back converging close to the umbilical scar.

RESUMO

Se realizó la disección de 40 piezas anatómicas de la especie humana, donde se describió la anatomía de las arterias del estómago, así como las variantes anatómicas encontradas y se realizó la morfometría del grosor de los vasos sanguíneos que conforman este sistema arterial. Se encontró que toda la irrigación destinada al estómago proviene del tronco celíaco, ya sea a través de troncos primarios, secundarios o terciarios. Se determinó que la arteria de mayor grosor en el feto es la hepática común, en el adulto es la arteria lienal y de los vasos que irrigan directamente al órgano, la gástrica izquierda para la curvatura menor y la gastroepiploica derecha en la mayor, ambas emiten el mayor número de ramos cortos a la pared en dichas curvaturas. Las variantes en nuestro material son escasas y siempre relacionadas con el sistema arterial de la curvatura menor y en específico de la arteria gástrica izquierda.


In this work, the dissection of 40 anatomic pieces of human specie was out, in which anatomy of stomach arteries was described , as well as anatomic variants found thickness morphometry of blood vessels which form the arterial system was performed. It was found the irrigation destined to stomach comes from celiac trunk, either trough primary, secondary or terciary tranks. It was determined that the artery with greater thickeness in the fetus is the common hepatic, in the adult is the lienal artery of vessels that directly irrigate to the organ, the left gastric for the lower curvature and the right gastroepiploic in the large, both emitthing the higher number of short branches to the wall in such curvature. Variants in our material are few and always related with the arterial system of the lower curvature and specifically in the left gastric artery.
