Little is known regarding the profiles of whole body donors in Muslim majority countries where donation is scarce. Therefore, this study aims to profile registered donors in Turkey by means of a survey. The explored data could be used to improve ongoing campaign efforts and ethical practices such as commemoration services. Registered donors of the donation programs at the two faculties of medicine of Istanbul University were compared with the national population and a cluster analysis was performed to reveal any concealed sub‐groups. Data from 188 respondents were analyzed. The majority of registered donors were married (42%), male (65.4%), aged over 50 years (76%), held a tertiary education degree (49.7%), and were irreligious (58.5%). Cluster analysis revealed two groups with significantly different educational levels, marital statuses, and religious choices. Regarding whether their bodies could be used for education or research, the majority (64.5%) of the respondents left the decision to the anatomy department. Similarly, 73.8% approved indefinite use of their organs, body parts and/or skeletons. The respondents were also willing to share their medical history (94.2%) and personal information (81.6%) if needed. Motivational themes for body donation including usefulness, impermanence, religion, awareness, and kinship were devised after a thematic analysis. Among the respondents, 56.5% were registered organ donors and 63.3% were frequent blood donors. The results of this study provide data that may help revising informed consent forms, developing and implementing thanksgiving ceremonies, and selecting additional targets for supporting body donation campaign activities such as organ and blood donation units.
The pterion is an important skull landmark because it is located where the frontal, the great wing of sphenoid, parietal, and squamous parts of the temporal bone junction. The objectives of this study were to determine the localization and the shape of pterion on skulls and to find out the distances between the pterion and some certain anatomic landmarks on neighboring structures. The study was performed on the skulls of 128 (256 sides) adult West Anatolian people. All of the morphometric measurements of the distances between the pterion and the anatomic landmarks were performed using a Vernier caliper with an accuracy of 0.1 mm. The pterion was classified into 4 types: the sphenoparietal, frontotemporal, stellate, or epipteric types. The incidences of types of pterion in the skulls were also found as the sphenoparietal type (85.2%), the epipteric type (8.2%), the stellate type (5.5%), and the frontotemporal type (1.1%). The mean (SD) distances from the center of the pterion to the zygomatic arch were measured as 40.02 (4.06) mm and 39.88 (4.01) mm; to the frontozygomatic suture, 31.80 (4.51) mm and 31.44 (4.73) mm; to the zygomatic angle, 41.54 (4.95) mm and 41.35 (5.14) mm; to the mastoid process, 82.48 (5.45) mm and 81.81 (5.50) mm; and to the external acoustic meatus, 53.29 (4.55) mm and 56.22 (4.60) mm, on the right and left sides, respectively. The mean (SD) distances between the foremost point of pterion and the anterior edge of the lateral wall of the orbit were 31.02 (5.78) mm and 32.31 (5.79) mm on the right and left sides, respectively. The localization and the shape of pterion are of importance because it is an anatomic landmark and should be of use in surgical approaches and interventions via the pterion.
Surgery is the preferred treatment method for hepatic malignancies. Due to advanced tumor stage and accompanying cirrhosis, most cases are considered inoperable at the time of diagnosis (1). It is well known that the blood supply to liver malignancies is typically arterial, unlike the parenchyma, which is supplied by the portal vein (2). Apart from being the main arterial supply to the diaphragm, the right and left inferior phrenic arteries (RIPA and LIPA), are extrahepatic collateral arterial pathways that supply hepatic malignancies, because they neighbor hepatic segments as they traverse the bare area of the liver (3,4). Among the arterial pathways that supply liver malignancies, both RIPA and LIPA constitute nearly half of the collaterals, with RIPA being the most common and LIPA being the 4th or 6 th most common (5,6). Therefore, both RIPA and LIPA are used during transcatheter arterial chemoembolization of liver malignancies (5-7). Furthermore, LIPA gives branches that supply the stomach and esophagus and can be a source of arterial bleeding at the esophagogastric junction (8)(9)(10)(11)(12).In this study, we aimed to investigate the anatomy of the inferior phrenic arteries -with special reference to the branches of the LIPA -and to outline their clinical importance with anatomical pitfalls which we believe may help interventional radiologists.Background: Transcatheter arterial chemoembolization is a common treatment for patients with inoperable hepatocellular carcinoma. If the carcinoma is advanced or the main arterial supply, the hepatic artery, is occluded, extrahepatic collateral arteries may develop. Both, right and left inferior phrenic arteries (RIPA and LIPA) are the most frequent and important among these collaterals. However, the topographic anatomy of these arteries has not been described in detail in anatomy textbooks, atlases and most previous reports. Aims: To investigate the anatomy and branching patterns of RIPA and LIPA on cadavers and compare our results with the literature. Study Design: Descriptive study. Methods: We bilaterally dissected 24 male and 2 female cadavers aged between 49 and 88 years for this study. Results:The RIPA and LIPA originated as a common trunk in 5 cadavers. The RIPA originated from the abdominal aorta in 13 sides, the renal artery in 2 sides, the coeliac trunk in 1 side and the left gastric artery in 1 side. The LIPA originated from the abdominal aorta in 9 sides and the coeliac trunk in 6 sides. In 6 cadavers, the ascending and posterior branches of the LIPA had different sources of origin. Conclusion: As both the RIPA and LIPA represent the half of all extrahepatic arterial collaterals to hepatocellular carcinomas, their anatomy gains importance not only for anatomists but interventional radiologists as well.
Objective: To determine not only the vertical but also horizontal localization of the adductor hiatus (AH) and classify its shape and structure macroscopically.Material and Methods: Forty lower extremities were dissected to expose the AH. Its shape and structure were macroscopically noted, and the AH was classified into four types. For determining the localization, measurements were made with digital calipers.Results: Twenty-four oval fibrous types, 12 oval muscular types, 2 bridging fibrous types and 2 bridging muscular types of AH were determined. For the horizontal localization of AH, the apex of the AH was determined to be located medial to the vertical line between the midpoint of the interepicondylar distance and the line which was drawn transversely from the apex of the AH, in all of the cadavers. For the vertical one, the apex of the AH was located in the middle third of the femur length in 14 thighs, and in the remaining 26 ones, the apex of the AH was located in the distal third of the femur length. Conclusion:Adductor hiatus was classified according to its shape and structure for the first time. Moreover, the localization of the AH was practically defined, in order not to harm the popliteal artery and vein.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
