Age-Dependent Changes in Diameters of Abdominal Visceral Arteries in Children
(Springer, 2024) Ten, Baris; Beger, Burhan
Purpose The diameters of the abdominal aorta and its branches are affected by demographic properties of patients like age, sex or body mass index. Some researchers use the body of the first lumbar vertebra (L1) as an anatomical indicator to create an exact standard for diagnosing arterial aneurysms or stenoses. In this regard, this work designed to uncover relations of abdominal visceral arteries with L1 in normal children using their abdominopelvic computed tomography images. Materials and methods The study population consisted of 180 subjects (age range 1-18 years) without any abdominopelvic disorders. The diameters of the abdominal visceral arteries were measured and the ratios of these arteries to L1 were calculated. Results The diameters of the abdominal visceral arteries increased from infancy period up to postpubescent period (p < 0.001), but L1's diameter did not change after late childhood period. Measurements in males were statistically similar to those in females, excepts from the transverse diameter of L1 (p = 0.001), the diameter of the common hepatic artery at the distal level (p = 0.002), and the diameter of the inferior mesenteric artery at the distal level (p = 0.019), which were greater in males than females. The ratios of diameters of the abdominal visceral arteries to L1 increased with advancing age (p < 0.001). Ratios in males were statistically similar to those in females (p > 0.05). Conclusion Our age-specific diameters and ratios regarding abdominal visceral arteries may facilitate the diagnosis of vascular disorders in children.
Effective Diameter of the Abdominal Aorta in Children
(Springer France, 2024) Beger, Burhan; Ten, Baris
Purpose Measure out of the standard interval in the aorta diameter is a clue for aortic aneurysm or hypoplasia. Pediatric studies focusing specifically on the normal diameter of the abdominal aorta (AA) were limited in the literature. Therefore, the main goal of this work was to determine changes in the effective diameter of AA in healthy children aged 1-18 years for diagnosis of vascular diseases. Methods This retrospective work focused on abdominopelvic computed tomography views of 180 children (sex: 90 males / 90 females, average age: 9.50 +/- 5.20 years) without any abdominopelvic disease to measure diameters of AA, common iliac artery (CIA), external iliac artery (EIA), and first lumbar vertebra (L1). Results Vessel and vertebra diameters increased in pediatric subjects between 1 and 18 years (p < 0.001). Considering pediatric age periods, vessel diameters increased steadily, but L1 diameter showed an irregular growth pattern between age periods. All parameters were greater in males than females (p < 0.05), except from effective diameters of AA over the coeliac trunk (p = 0.084) and over the renal artery (p = 0.051). The ratios of diameters of vessels to L1 increased depending on ages between 1 and 18 years. Considering pediatric age periods, the ratios increased from infancy period to postpubescent period in irregular pattern; however, the ratios for right and left CIA, and AA over the aortic bifurcation did not alter after late childhood period. All ratios for males were similar to females (p > 0.05). Conclusion Our age-specific ratios may be beneficial for surgeons and radiologists for the diagnosis of vascular disorders such as aortic aneurysm.
Ischiofemoral Space Dimensions for Ischiofemoral Impingement: Is It Different in Children
(Springer, 2022) Ten, Baris; Beger, Orhan; Balci, Yuksel; Duce, Meltem Nass; Beger, Burhan
Objective This study intended to analyze alterations in ischiofemoral space (IFS) dimensions in normal children between the ages of 1 and 18 years for the ischiofemoral impingement. Materials and methods This study retrospectively focused on computed tomography images of 360 hips of 180 (90 boys and 90 girls) pediatric subjects (mean age: 9.50 +/- 5.20 years, range: 1-18 years) without any hip disorders to measure IFS, femoral neck angle (FNA), and ischial angle (IA). Results Mean IFS, FNA, and IA were measured as 14.64 +/- 7.24 mm, 34.61 +/- 11.47 degrees, and 131.52 +/- 4.22 degrees, respectively. IFS increased in children aged between 1 and 18 years, whereas FNA and IA decreased. IFS was similar in infancy and early childhood periods but then increased up to postpubescent period. FNA decreased proportionally from birth, whereas IA decreased in an irregular pattern. Linear functions were detected as y = 3.451 + 1.178 x years for IFS, as y = 48.555 - 1.468 x years for FNA, and as y = 132.535 - 0.107 x years for IA. Conclusion Our findings indicate that IFS tends to increase in size with age during childhood but decreases with further aging. Therefore, age-specific values for IFS, FNA, and IA may be beneficial for clinicians and radiologists for the diagnosis of ischiofemoral impingement.
Morphologic Evaluation of the Coccyx in the Pediatric Population
(Springer France, 2025) Meylani, Nevzat; Ten, Baris; Temel, Gulhan; Yuksek, Hasan Husnu; Comert, Ali Danyal; Beger, Burhan; Beger, Orhan
Purpose This computed tomography study aimed to display the alteration in the coccyx morphology (its ossification process, dimension and angulation) in children with advancing age. Methods Pelvic radiologic scans of 180 children aged 1-18 years were retrospectively evaluated to observe changes in the coccyx morphology with age, and to measure the linear length (LL), curvilinear length (CLL), sacrococcygeal angle (SCA), and intercoccygeal angle (ICA). Results The present study divides the postnatal evolution of the coccyx into three phases as follows: (a) in the first stage when the coccyx is of the shortest, it is completely cartilage until the age of 2 (infancy period) and its first segment begins to ossify by the age of 3 (early childhood period), (b) in the second stage when the coccyx is of medium size, its first segment is completely ossified by the age of 6 (late childhood period) and the ossification of its all segments is completed from the age of 11 (prepubescent period), and (c) in the third stage when the coccyx is of the longest, it reaches to adult size (postpubescent period). Linear functions were calculated as y = 15.647 + 1.145 x age (p < 0.001, R-2 = 0.561) for LL, and as y = 16.829 + 1.243 x age (p < 0.001, R2 = 0.559) for CLL. Conclusion Considering that morphological features of the coccyx, such as ICA, can be used in the diagnosis of coccydynia, our dataset may facilitate the identification of children with suspected coccydynia.
