Variations of testicular vessels are more common than supposed. The testicular artery varies because of abnormal regression of the lateral mesonephric arteries in the fetus, whereas variations in the testicular vein are due to abnormalities in the involution of the intersubcardinal anastomosis. Such variations are usually found incidentally during surgical procedures around the renal pedicle and they often lead to complications. Several authors have attempted to classify them. However, these attempts have not been comprehensive. Therefore, the aim of this study is to provide a simple yet comprehensive classification of variations of the testicular vessels. The PubMed database was searched using keywords pertaining to the testicular vessels. The results were subjected to the Anatomical Quality Assessment (AQUA) tool analysis and were screened for appropriateness for inclusion in this study. The screening procedure yielded 31 original articles, 83 case reports, and 1 review article. Both testicular arterial and venous variations were more common on the left side (20.73% and 24.61%) than the right (12.69% and 18.4%, respectively). We classified the testicular arteries on the basis of their number (N), site of origin (O), and course (C). Similarly, the testicular veins were classified on the basis of their number (N) and site of drainage (D). The proposed classification facilitates identification, understanding, and reporting of variations of the testicular vessels by radiologists. It will also help surgeons to enhance the quality of their treatment. Clin. Anat. 31:854-869, 2018. © 2018 Wiley Periodicals, Inc.
Learning anatomy by dissection of cadavers is the best way to learn anatomy. Voluntary body donation is one of the sources of procuring cadavers. In the case of donations after hospital or non-institutional deaths, the family members of the deceased approach the hospital authorities regarding body donation of the deceased. There are situations, where there is no available accompanying near relatives of the deceased, which pose a challenge for personnel involved in the process of body donation. In two of the reported cases, the body donation was done by the live-in partner and a friend of the deceased. In another reported case, the son of the deceased was nominated by the donor at the time of registration. As the son of the deceased was not available at the time of death of the donor, donation was executed by another near relative. Anatomy Acts of individual States in the Union of India and Acts of other countries are examined about the consent for body donation by persons other than near relatives. None of the Anatomy Acts of various States in India provide an alternative in the absence of near relatives for claiming the body or for donating the body, except for Acts of Delhi and Kerala. There is a need to bring in a Unified Anatomy Act, common for all the States and Union territories in India and include: friend, live-in partner and a nominated person in the provisions of the Act to enable them to give consent for body donation.
IntroductionThis study was done to analyze the morphometric features of the inguinal canal with different types of inguinal hernias to determine the appropriate size of mesh required to cover potential sites of recurrence. A morphometric assessment in the particular population is essential to recommend the appropriate mesh size in inguinal hernias to cover all the potential sites of recurrence.Materials and methodsThis was a prospective observational study, including all consecutive patients undergoing open inguinal hernia repair under local/regional/general anesthesia over a period of three years. Surgeries that were done in emergencies for complicated hernias, laparoscopic repair, and recurrent inguinal hernias were excluded. Intra-operative parameters were studied to predict the appropriate mesh size, which included the position of the superficial and deep inguinal ring (SIR and DIR) with the diameter, the distance of SIR and DIR from the anterior superior iliac spine (ASIS), and the distance from the summit of the muscular arch to the inguinal ligament. The differences in morphometric details between the types of hernias and categorical variables were assessed using the chi-square test.ResultsThe study included a total of 170 patients with a mean age of 50.67 + 17.59 years. An indirect hernia was the most common type in patients less than 60 years. The mean distance from ASIS to SIR was 10.2+ 1.9 cm, and in indirect hernia patients, it was found to be significantly increased (p=0.042). The mean distance from ASIS to DIR was 4.14+1.57 cm, where the indirect hernia patients had a significantly less distance (p=0.029). The mean length of the inguinal canal in a direct hernia was 5.66 + 0.5 cm, whereas, in an indirect inguinal hernia, it was 6.46 + 0.8 cm, which was significant (p=0.029). The mean distance from the midpoint of the inguinal ligament to the summit of the muscular arch was 4.03 cm, and there was no significant difference between the indirect and direct hernia patients.ConclusionAfter considering the morphometric assessments of the length of the inguinal canal, the mean distance from the midpoint of the inguinal ligament to the summit of the muscular arch, the mean distance from ASIS to DIR, the ideal mesh size for the population would be 9 X 15 cm to cover all the potential sites of recurrence.
Pulleys are thickened regions in flexor tendons sheaths of the digits. They are essential and act as fulcrum for the flexion and extension of the digits. The arrangement and number of pulley system differs greatly between the thumb and other digits. There is paucity of literature regarding the pulley system of thumb. We aimed to study the morphometry of the pulley system of the thumb in Indian cadavers. Dissection was carried out in 55 adult human cadaveric thumbs. The most common morphologic pattern of pulley observed in the thumb is type III (30 thumbs). The least observed is type I (4 thumbs). The mean width and standard deviation of A1, Av, oblique, and A2 pulleys are 5.06±0.87, 5.38±1.22, 4.68±1.13, and 6.04±1.41 mm, respectively. The gap distances between the pulleys were also measured. The results obtained from the present study may be helpful in surgical treatment of trigger thumb with less complication and also in reconstruction of the closed rupture of the pulley of the thumb.
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.
