ABSTRACT

SUMMARY: Liver plays an important role in many events such as bile production, blood filtration and metabolic functions. The liver is supplied by the hepatic arterial system. The hepatic arterial system anatomy has a variable structure and the rate of variation is high. In our study, we aimed to determine the diameters and variation of the arteries supplying the liver with multidetector computed tomography images. In this study, hepatic arterial system variations of 500 cases whose abdominal region was imaged with multi- detector computed tomography were evaluated and the diameters of the related arteries were measured. The mean diameters of classical and variational anatomy were determined in this study. According to mean measurements of classical and variational anatomy were abdominal aorta 21.95 mm, celiac artery 7.2 mm, common hepatic artery 4.3 mm, proper hepatic artery 2.93 mm, right hepatic artery 2.92 mm, left hepatic artery 2.51 mm and abdominal aorta 21.85 mm, celiac artery 6.99 mm, common hepatic artery 5.07 mm, proper hepatic artery 3.83 mm, right hepatic artery 2.87 mm ve left hepatic artery 2.09 mm respectively. When evaluated in terms of variations, 85.6 % of the cases had branching according to Type I, 14.4 % of the cases had different branching patterns. Type III (87.5 %) was the most observed variation among them. As a result of the study, it was determined that the arterial diameters vary according to the state of variation and that the arterial diameter of men are greater than that of women.


RESUMEN: El hígado juega un papel importante en diferentes eventos, tal como la producción de bilis, la filtración de sangre y las funciones metabólicas. El hígado está irrigado por el sistema arterial hepático. La anatomía del sistema arterial hepático tiene una estructura variable y la tasa de variación es alta. En nuestro estudio, nuestro objetivo fue determinar los diámetros y la variación de las arterias que irrigan el hígado con imágenes de tomografía computarizada multidetector. Se evaluaron las variaciones del sistema arterial hepático de 500 casos y se obtuvieron imágenes con tomografía computarizada de detectores múltiples abdominales y se midieron los diámetros de las arterias relacionadas. Se determinaron los diámetros medios de la anatomía clásica y variacional. Según las medidas medias de la anatomía clásica y variacional fueron aorta abdominal 21,95 mm, arteria celíaca 7,2 mm, arteria hepática común 4,3 mm, arteria hepática propia 2,93 mm, arteria hepática derecha 2,92 mm, arteria hepática izquierda arteria 2,51 mm y parte abdominal de la aorta 21,85 mm, arteria celíaca 6,99 mm, arteria hepática común 5,07 mm, arteria hepática propia 3,83 mm, arteria hepática derecha 2,87 mm y arteria hepática izquierda 2,09 respectivamente. Cuando se evaluó en términos de variaciones, el 85,6 % de los casos tenían ramificaciones según el Tipo I, el 14,4 % de los casos tenían diferentes patrones de ramificación. El tipo III (87,5 %) fue la variación más observada entre ellos. Como resultado del estudio, se determinó que los diámetros arteriales varían según el estado de variación y que el diámetro arterial de los hombres es mayor que el de las mujeres.

ABSTRACT

Background: To determine the types, frequency and clinical implications of formation of variations of portal vein with routine abdominal multi detector CT.Methods: MDCT images of 265 patients without any pathology were evaluated. Types and frequencies of formation variations of portal vein were determined.Results: Portail vein formation variations were observed in 186 (70.15%) of our study population. Normal portal vein was detected in 79 (29.8%) images. These variations were classified according to frequency. Normal anatomic structure was determined as type 1. Type 1 was observed in 79 (29.8%) images. As type 2 variation, left gastric vein flows into splenic vein instead of portal vein (60.75%). The type 3 of portal vein variation as uniting of superior mesenteric vein, inferior mesenteric vein and splenic vein at the same trunk to form portal vein was determined 9.43%.Conclusions: This study, which was performed to determine the anatomical variations of portail vein, makes the type 2 variation rate higher than the other studies. This information is different from the classical anatomy information. In addition, we are able to make the radiologists and surgeons highly capable of both recognition and functionality of the results.

ABSTRACT

La gastrostomía endoscópica percutánea (GEP) se utiliza como alternativa de la alimentación enteral/nasoenteral en situaciones en las que la alimentación por vía oral a largo plazo no es eficaz o no se tolera. Se prefiere principalmente en pacientes con afecciones neurológicas y, además, como apoyo de la nutrición en pacientes con enfermedades cardíacas congénitas, fibrosis quística, enfermedad intestinal inflamatoria y diversas enfermedades orofaríngeas. Si bien la colocación es sencilla en comparación con muchos procedimientos invasivos, presenta complicaciones, que incluyen desde la infección de la herida hasta la muerte. La GEP exige personal médico experimentado, antibióticos profilácticos adecuados e información exhaustiva para los pacientes o sus familias sobre el procedimiento y los cuidados posteriores. Presentamos una complicación rara, aunque importante, que surgió durante el reemplazo de la sonda de gastrostomía después del método de "corte y empuje". El tope, que debe llegar hasta el extremo distal del estómago, se desplazó hacia arriba, hasta el esófago proximal, y causó una úlcera profunda en la mucosa esofágica y una hemorragia masiva.


Percutaneous endoscopic gastrostomy (PEG) is used as an alternative to enteral/nasoenteral feeding in situations where long-term oral feeding is ineffective or not tolerated. It is mostly preferred in patients with neurological conditions and also to support nutrition in patients with congenital heart diseases, cystic fibrosis, inflammatory bowel disease, and various oropharyngeal diseases. Although it is easily applicable compared to many invasive procedures, it has complications ranging from wound infection to death. PEG requires experienced medical personnel, appropriate prophylactic antibiotics and exhaustive information to the patients or their families about the procedure and subsequent care. We present a rare but important complication during the replacement of the gastrostomy tube subsequent to the "cut and push" method. The bumper portions, which should move to the distal end of the stomach, moved upwards to the proximal esophagus, caused a deep ulcer in the esophageal mucosa and a massive hemorrhage.
