The purpose of this study was to understand the clinical significance of the morphology and blood supply of the falciform ligament in laparoscopic surgery. The structure, blood vessel distribution and anastomoses of the falciform ligament were observed in 20 cases of living laparoscopy, 30 cadaveric specimens injected with latex and five cadaveric specimens with Indian ink and hyaline. The falciform ligament was formed by two sides of peritoneum and its length, largest and smallest width were 8.3+/-1.6 cm, 4.9+/-0.8 cm and 1.1+/-0.3 cm, respectively. The left inferior phrenic artery and middle segment artery of the liver formed a vessel that arched and gave off 6-12 branches to the falciform ligament. The veins of the falciform ligament drained into the left inferior phrenic vein, and were not accompanied by any artery. In conclusion, the vessels of the falciform ligament anastomose with multiple vessels and form a significant pathway of the collateral circulation in the liver. The falciform ligament is an important landmark in laparoscopic surgery.
The influence of human leukocyte antigen (HLA) matching on graft survival is greater in patients with preformed lymphocytotoxic antibodies than in nonsensitized patients. Pretransplant serum soluble CD30 (sCD30) affects graft outcome independently of presensitization status. The impact of HLA compatibility on kidney transplant survival was analyzed in 3980 nonsensitized first cadaveric kidney recipients in relation to the pretransplant serum sCD30 content. Although HLA compatibility influenced graft outcome only marginally in nonsensitized recipients with low sCD30 (at 3 years: P=0.0095; at 5 years: P=0.1033), a strong HLA matching effect was observed in nonsensitized recipients with high sCD30 (at 3 years: P<0.0001; at 5 years: P=0.0001). Nonsensitized patients with high pretransplant sCD30 benefit from an HLA well-matched kidney. Patients should be tested for sCD30 while on the waiting list for a kidney transplant, and HLA well-matched kidneys should be allocated to patients with high sCD30.
The cochlea has attained extreme surgical interest since cochlear implantation has been recognized as an established method for the management of certain types of bilateral profound hearing loss. Traditionally access to the cochlear turns is achieved through the middle ear. Extremely limited references exist in the literature regarding alternative surgical approaches to the cochlea. In the present study we tried to highlight the anatomic relationships of the superior aspect of the bony cochlea to the adjacent superficial structures of the petrous bone, as there have been suggestions that the cochlea is surgically accessible through the floor of the middle cranial fossa (MCF). A total of 58 dry human adult skulls (116 temporal bones) were studied. The groove for the greater superficial petrosal nerve (GGSPN) and the facial hiatus were used as landmarks in order to expose the superior aspect of the cochlea. Measurements were made of the following distances: a) between the MCF floor and the superficial part of the basal turn (SPBT), b) between the MCF floor and the apex of the cochlea, c) between the SPBT and the GGSPN and d) between the SPBT medially and the first genu of the facial canal laterally. Our results indicate that adequate and reliable surgical access to the bony cochlea could be achieved through the MCF floor.
