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.

(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.

(SpringerNature, 2025) Ten, Baris; Beger, Orhan; Comert, Ali Danyal; Beger, Burhan
ObjectiveThe study was planned to evaluate the size, shape and prevalence of the accessory spleen (AS) in healthy children aged 1-18 years using their abdominopelvic computed tomography images.MethodsPediatric subjects, who underwent abdominopelvic radiologic scan and admitted to the hospital between January 2011-December 2020 were included into the study for the detection of AS incidence. The antero-posterior, medio-lateral and supero-inferior diameters of AS and spleen were measured. In addition, the shape and localization of AS were noted.ResultsThe study population consisted of 3738 normal pediatric subjects (2320 males and 1418 females) aged 1-18 years. AS was found in 461 (12.3%) of this population. In addition, 92 (19.7%) out of 461 cases had more than one AS. Of the subjects with AS, 292 were male and 169 were female. The dispersion ratio of AS incidence in males and females proved that AS incidence did not correlate with sex (p = 0.291). Measurements in males were statistically similar to those in females, excepts from the supero-inferior diameter of the spleen (p = 0.036), which was greater in males than females. According to age groups, AS size did not change after early childhood period, but the size of the spleen increased up to postpubescent period. The most common location of AS was the middle third of the main spleen (23.9%). There were two different shapes of AS: 80% were round and 20% were ovoid.ConclusionApproximately one in eight children has an AS, which is round and well-marginated mass. It reaches adult size in late childhood period (i.e., from the age of six). Approximately one in four ASs was located at the middle third of the spleen.

(SpringerNature, 2025) Yaman, Zafer Kaan; Ten, Baris; Temel, Gulhan; Yuksek, Hasan Husnu; Comert, Ali Danyal; Beger, Burhan; Beger, Orhan
Purpose To demonstrate age-dependent changes in dimensions of C6-T3 vertebrae in children for pedicle screw surgery. Methods Radiologic images of 180 pediatric subjects aged 1-18 years were evaluated retrospectively. Results In all vertebrae (C6-T3) at the cervicothoracic junction, the pedicle thickness (p < 0.001), pedicle axis length (p < 0.001), pedicle height (p < 0.001), spinal canal's transverse diameter (p < 0.001), spinal canal's sagittal diameter (p < 0.001) and interpedicular distance (p < 0.001) increased with advancing pediatric age (from one year to 18 years), but the transverse and sagittal pedicle angles decreased (p < 0.001). From C6 to T3, the pedicle axis length (p < 0.001) and sagittal pedicle angle (p < 0.001) increased proportionally, but the spinal canal's transverse diameter (p < 0.001) and transverse pedicle angle (p < 0.001) decreased proportionally. The pedicle height (p < 0.001) decreased from C6 to C7, but then increased until T3. The interpedicular distance (p < 0.001) increased from C6 to C7, but then decreased until T3. The pedicle thickness (p < 0.001) increased from C6 to T1, and then decreased up to T3. The spinal canal's sagittal diameter (p < 0.001) was statistically similar in C6 and C7, but then increased up to T2. Conclusion Our morphometric data regarding vertebral pedicle anatomy located at the cervicothoracic junction may be beneficial for surgeons to form a region-specific clinical strategy in children.
