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

The external carotid artery (ECA) is the main artery of the head and the neck region. Carotid bifurcation (CB), which is one of the place where the atherosclerotic plaques are most commonly seen. The surgical procedure of these plaques which causes cerebral vascular accident (CVA) is carotid endarterectomy. In this surgical procedure, the knowledge of the anatomical courses and variations of the carotid artery increased the surgery performance. In our study, we aimed to introduce the course, the location and the variation of the ECA's and their branches. This study is carried out on multidetector computerized tomography angiography of the ECA's of 50 men and 50 women, totally 200 ECA's (100 right, 100 left). The measurement of the inner diameter of the common carotid artery (CCA) and the ECA was evaluated. The location of the CB was determined and its vertical distance to the gonion measured. We found that the superior thyroid artery (STA) originated from the CCA, the CB and the ECA. The vertical distances between the CB and the STA, lingual (LA), facial (FA) occipital (OA) were measured. The ECA and its branches were recorded. We believe that the assessment of the ECA morphometrically may comprise control groups of diseases related to the vessel diameter and this data may be used as reference in clinic and surgery. Knowing the anatomical details and variations is vital to prevent unpredictable complications in surgery.


La arteria carótida externa (ACE) es la principal arteria de la cabeza y de la región del cuello. La bifurcación carotídea (BC) es uno de los lugares donde las placas ateroscleróticas son más frecuentes. El procedimiento quirúrgico para tratar estas placas que causan el accidente vascular cerebral (AVC) es la endarterectomía carotídea. En este procedimiento quirúrgico, el conocimiento de los cursos anatómicos y variaciones de la arteria carótida aumenta el rendimiento de la cirugía. El objetivo de nuestro estudio fue presentar el trayecto, localización y variación de la ACE y sus ramas. El estudio se realizó mediante angiografía multidetector por tomografía computarizada de la ACE de 50 hombres y 50 mujeres, totalizando 200 ACE (100 derechas y 100 izquierdas). Se evaluaron el diámetro interior de la arteria carótida común (ACC) y la ACE. Se determinó la ubicación de la BC y se midió la distancia vertical hasta el gonion. Se observó que la arteria tiroidea superior (ATS) se originó desde la ACC, la BC y la ACA. Las distancias verticales entre la BC, y las arterias tiroídea superior, lingual (AL), facial (AF) y occipital (AO) fueron medidas. La ACE y sus ramas se registraron. Creemos que la evaluación morfométrica de la ACE puede comprender grupos de control de las enfermedades relacionadas con el diámetro de los vasos, y estos datos pueden ser utilizados como referencia clínica y quirúrgica. El conocimiento de los detalles anatómicos y variaciones es de vital importancia para evitar complicaciones imprevisibles en la cirugía.

ABSTRACT

Anomalies of the bronchial tree may cause recurrent acute pulmonary infection and persistent obstruction symptoms. The developmental anomalies of the bronchial tree were presented mostly as case reports with an accompanying anomaly. However in this study, these anomalies were detected in multidetector computerized tomography (MDCT) images which have no reported pathology. Thoracic MDCT images of 400 patients (0-74 years old, 224 male and 176 female) were evaluated. Four tracheal bronchus (1percent) were detected. Three of them were displaced type, one of them was pig bronchus. And two accessory cardiac bronchus (0,5 percent) originated from medial wall of the intermediate bronchus were detected. According to our findings, incidence of tracheal bronchus and accessory cardiac bronchus seems to be higher in Turkish population.


Las anomalías del árbol bronquial pueden causar una infección pulmonar aguda recurrente y síntomas de obstrucción persistente. Las anomalías del desarrollo del árbol bronquial se presentan principalmente como informes de casos con una anomalía de acompañante. Sin embargo, en este estudio se detectaron estas anomalías en las imágenes de tomografía computarizada multidetector (TCMD), donde no se habían informado esta patología. Se evaluaron las imágenes de TCMD torácica de 400 pacientes (0-74 años, 224 hombres y 176 mujeres). Se detectaron cuatro bronquios traqueales (1 por ciento). Tres de ellos fueron de tipo desplazado, uno fue tipo bronquio de cerdo, y dos bronquio cardiaco accesorio (0,5 por ciento), originados de la pared medial del bronquio intermedio. De acuerdo con nuestros resultados, la incidencia de bronquio traqueal y bronquios cardiacos accesorios parecen ser mayor en la población turca.

ABSTRACT

Variations in the branches of the abdominal aorta were determined during a routine abdominal region dissection of a 70-year-old male cadaver. Left gastric artery arose as the first root from antero-lateral of aorta. Coeliacomesenteric trunk occurred as a thick root. After 29.9mm, coeliacomesenteric trunk bifurcated as coeliac trunk and superior mesenteric artery. Coeliac trunk bifurcated as splenic artery and common hepatic artery. These multiple variations which change the normal anatomic structure of the abdominal aorta have to be kept in mind by surgeons, radiologists and anatomists.


Fueron encontradas, en un cadáver de sexo masculino de 70 años de edad durante una disección de rutina de la cavidad abdominal, variaciones de las ramas en la parte abdominal de la aorta. La arteria gástrica izquierda se originaba como la la primera rama antero-lateral de la aorta. El tronco celiacomesénterico se originó desde la aorta como una raíz gruesa. Después de 29,9mm, el tronco celiacomesentérico se dividió en el tronco celíaco y la arteria mesentérica superior. El tronco celíaco se dividió en las arterias esplénica y hepática común. Estas variaciones múltiples que cambian la estructura anatómica normal de la parte abdominal de la aorta tienen que ser tomada en consideración por los cirujanos, radiólogos y anatomistas.
