“…Previously, these fissures have been stated to occur more commonly in the RLs followed by the QL which is not the observation in our study [2,4]. In the CL, 71.4% were vertical fissures in our study in comparison to 30-35% in other studies [11]. Rest was mainly transverse and oblique in nature.…”

IntroductionWith increasing dependence on laparoscopic procedures, precise knowledge of external variations of the liver is essential for good surgical and interventional outcomes, preventing imaging misdiagnosis, and curtailing complications. The present study aims to evaluate the gross anatomical variations of the liver. Materials and MethodsThe 40 adult cadaveric livers of age 60-80 years were removed during the routine dissection for undergraduate medical students and examined for morphological variations in the form of size, shape, and fissures. ResultsAccessory fissures were observed on the caudate lobe (CL) in 23 (57.5%), on the quadrate lobe (QL) in seven (17.5%), on the right lobe (RL) in 29 (72.5%), and on the left lobe (LL) in 12 (30%) specimens. Netter's Type 2, Type 4, Type 5, Type 6, and Type 7 liver were observed in four (10%), seven (17.5%), one (2.5%), three (7.5%), and three (7.5%) specimens respectively. The most common shapes of the CL and QL were rectangular in 16 (40%) and quadrangular in 10 (25%) specimens respectively. Pons hepatis were seen in three (7.5%) specimens. The mean length (cm) of RL and LL were 17.75 ±3.09 and 16.9±3.69 respectively, whereas the mean transverse diameter (TD) (cm) of RL and LL were 7.98±1.20 and 7.85±1.58 respectively. The mean length and TD (cm) of CL were 5.62±1.67 and 2.48±1.00 respectively. The mean length and TD (cm) of the QL were 6.00±1.51 and 2.81±0.83 respectively. ConclusionPrecise knowledge of these variations would be helpful for surgeons in planning and performing surgical procedures and for anatomists.

“…Reddy et al described a prominent PP in 46.25% and a very prominent PP in 18.9% but in our study 32.5% and 17.5% respectively [11]. Chavan and Wabale observed the absence of PP in all livers whereas in our study it is 7.5% [12].…”

“…According to Sagoo and colleagues, the rectangular shape of the caudate lobe was found in the majority of cases in NWI population livers, In 35% of the livers, they discovered a vertical fissure extending upward from the lower border of the caudate lobe (Reddy et al, 2017). They also discovered caudate processes in all of the examined livers, which were of varying thickness.…”

The caudate lobe is a vertically elongated central projection from posterior surface of liver. It is bordered on the right by the groove for the inferior vena cava (IVC), on the left by the fissure for the ligamentum venosum, and on the bottom by the porta hepatis. It is continuous on the superior aspect with the upper part of the right limb of the fissure for the ligamentum venosum. The morphology of the caudate lobe was studied in 100 cadaveric human livers (15-70 years old) stored in 10% formaldehyde, regardless of gender, obtained from the department of anatomy at Santosh Medical College in Ghaziabad. The caudate lobe was observed in a variety of shapes. Vertical fissures extending upward from the lower border of the caudate lobe were seen in 52% of the liver specimens, while accessory caudate fissures extending downward from the upper border were seen in 9% and accessory transverse fissures were seen in 3% cases. Caudate notch was horizontal in 11% of liver specimens. The papillary process was visible in 27% of the liver specimens; a hook shape of the papillary process was seen in one liver specimen. Caudate process was present in 18% of the cases. Linguiform process was observed in 46% of cadaveric liver specimens. As observed, the incidences of morphological variations of the caudate lobe are very high, so it is critical for both radiologists and surgeons to keep these variations in mind when making diagnoses and planning surgeries for a favourable clinical outcome.

Sinuses of Valsalva height is an important parameter in planning cardiac surgery, percutaneous coronary intervention and transcatheter aortic valve implantation (TAVI). The aim of the study is to analyze the height of the sinuses of Valsalva depending on height, weight, body mass index, body surface area, and sex using computed tomography angiography images in Ukrainian population. 59 chest computed tomography angiography examination for non-cardiac reasons were retrospectively evaluated. Data were collected from Ukrainian citizen. The height of the Sinuses of Valsalva was measured as the distance between aortic annulus and sinotubular junction. All three sinuses of Valsalva height were higher in men than in women (p<0.001). In men, three Sinuses of Valsalva had a correlation with height and body surface area (BSA) (р<0.05). In women, a correlation has been confirmed only between anthropometric measurements and the height of left and right coronary sinuses (р<0,05). The left coronary sinus height had a correlation with height, weight, body mass index (BMI) and BSA (р<0,05). The right coronary sinus height had a correlation with weight, BMI, and BSA (р<0.05).The parameters of the non-coronary sinus in women do not have confirmed direct correlations with any anthropometric measurements observed.The sinuses of Valsalva height is higher in males.The most significant confirmed correlations were between height and left and right coronary sinuses in men and women. Increased size of sinuses in men correlated with an increase of height, weight and decrease of BMI and BSA values.
