Background and Aim: Palmar arterial supply is mainly provided by the superficial palmar arch (SPA). Ulnar artery primarily completes the arterial arcade of  the superficial palmar arch. Radial artery grafts and reconstructive hand surgery benefit from understanding the variations in SPA formation. The present study is aimed to analyze the vascular pattern of the superficial palmar arch.  Materials and Methods: This cross-sectional study was conducted in the Department of Anatomy, Bacha Khan Medical Complex Mardan and Multan Medical & Dental College, Multan from October 2019 to September 2022 on 60 specimens, 46 male and 14 females. Due to inconvenient sampling, all cadaveric hands studied during the three years in the dissection room of the anatomy department were not calculated. An incision was made along the root of the fingers and another at the wrist joint. The 3rd metacarpo-phalangeal joint was incised vertically from the middle of the wrist. Reflection of the skin and aponeurosis of the palm was done. An area of adipose tissue around the superficial palmar arch was removed to observe the arches and their branches. Variations were noted in the superficial palmar arches.

In the human body; the major lymphatic organ is the spleen supplied by the splenic artery, the main division of the celiac trunk. It crosses the lienorenal ligament and approaches the spleen hilum where it splits into 2-3 main branches, each of which divides mainly into 2-4 secondary branches. Also, inferior and superior polar arteries arise from the primary branches or splenic trunk and pass into the spleen pole without entrance in the hilum. The purpose of this analysis was to understand the segmental branches morphometry of the polar and splenic arteries. Methods: The analysis was performed on 86 spleens collected from adult human cadavers of not known gender, stored in formalin 10% solution obtained from the Anatomy and Forensic Medicine Department, by dissection. Place and Duration: In the department of anatomy, Multan Medical and Dental College and Bacha Khan Medical Complex Swabi for six months duration, from August 2021 to January 2022. Results: In 59 (68.6%) spleen samples; there were 2 primary branches, 23 (26.7%) samples have three primary branches, and 4 (4.7%) specimens have four primary branches. 20 (23.3%) samples have superior polar arteries, 34 (39.5%) have inferior polar arteries, and both inferior and superior polar arteries in 7 (8.1%) samples. The superior polar artery length varies from 0.8-5.51 cm, with 2.80 cm of average length and 2.4 cm median length. The inferior polar artery length ranged from 0.9-5.90 cm, with 3.17 cm of average length and 3.30 cm median length. The superior PB diameter ranged from 0.8-4.12 mm, with 2.20 mm average length and 2.4 mm median length. The mean diameter of middle PB ranged from 0.8 mm to 3.6 mm, with an average of 2.10 mm and 2.4 mm median length. The PB inferior diameter ranged from 0.6 mm to 4.4 mm, with an average of 2.13 mm and 2.10 mm median length. The superior polar artery diameter ranged from 0.5-3.1 mm, with 1.40 mm average length and 1.4 mm of median. The inferior polar artery diameter varies from 0.5-2.9 mm, with 1.3 mm of an average diameter with 1.4 mm median. Conclusions: As various splenic sparing surgeries depend on better information of the vascular anatomy of the spleen, this analysis enhances the current information about the segmental branches’ morphometry of the splenic artery.
