A systematic review and meta-analysis: prevalence and clinical implications of anatomical variants of the hepatic portal vein.

The hepatic portal vein is the main vascular route responsible for collecting blood from the liver, spleen, pancreas, stomach, gallbladder, and intestines. Its key function is to metabolize the components acquired from the blood. The objective of this study was to analyze the characteristics of HPV variants and understand the possible clinical considerations that arise with them.

Anatomical Variants of the Origin of the Coronary Arteries: A Systematic Review and Meta-Analysis of Prevalence.

Purpose: The most common anomaly is an anomalous left coronary artery originating from the pulmonary artery. These variants can be different and depend on the location as well as how they present themselves in their anatomical distribution and their symptomatological relationship. For these reasons, this review aims to identify the variants of the coronary artery and how they are associated with different clinical conditions.

Gender and Mentorship in Military Medicine: A Survey Study.

Introduction: Mentorship is essential for professional development and advancement within the military. In civilian medicine, the intersection between gender and mentorship holds important implications for research opportunities, academic success, and career progression. However, the intersection of gender and mentorship has not yet been explored within the field of military medicine.

Essential anatomy for core clerkships: A clinical perspective.

Clerkships are defining experiences for medical students in which students integrate basic science knowledge with clinical information as they gain experience in diagnosing and treating patients in a variety of clinical settings. Among the basic sciences, there is broad agreement that anatomy is foundational for medical practice. Unfortunately, there are longstanding concerns that student knowledge of anatomy is below the expectations of clerkship directors and clinical faculty.

Chronic Atherothrombosis in a Sub-Massive Infrarenal Abdominal Aortic Aneurysm in a 91-Year-Old White Male Donor.

Screening for abdominal aortic aneurysms became the standard of care in 2005, yet screening procedures continue to be underutilized. While improvements in mortality rates have been noted over the past 15 years, continued patient mortality from ruptured abdominal aortic aneurysms suggests a need for further research, regarding the effectiveness of the current screening process. Abdominal aortic aneurysms can progress silently, and the risk of rupture increases significantly with increase in diameter.

A Hepatogastrophrenic Trunk, Celiacomesenteric Trunk, and a Middle Mesenteric Artery in a 68-Year-Old White Male Donor.

A detailed understanding of the enteric vascular supply is of great importance for pre-operative planning. In the case of this 68-year-old white male donor, the following variations were observed: a hepatogastrophrenic trunk, a celiacomesenteric trunk, and a middle mesenteric artery. Literature review was conducted to understand the frequency and clinical significance of these variations.

Enhanced Training Benefits of Video Recording Surgery With Automated Hand Motion Analysis.

Background: Hand motion analysis by video recording during surgery has potential for evaluation of surgical performance. The aim was to identify how technical skill during open surgery can be measured unobtrusively by video recording during a surgical procedure. We hypothesized that procedural-step timing, hand movements, instrument use and Shannon entropy differ with expertise and training and are concordant with a performance-based validated individual procedure score.

Frequency and Clinical Review of the Aberrant Obturator Artery: A Cadaveric Study.

The occurrence of an aberrant obturator artery is common in human anatomy. Detailed knowledge of this anatomical variation is important for the outcome of pelvic and groin surgeries requiring appropriate ligation. Familiarity with the occurrence of an aberrant obturator artery is equally important for instructors teaching pelvic anatomy to students.

Assessment of Anatomical Knowledge and Core Trauma Competency Vascular Skills.

Objectives: Surgical residents express confidence in performing specific vascular exposures before training, but such self-reported confidence did not correlate with co-located evaluator ratings. This study reports residents' self-confidence evaluated before and after Advanced Surgical Skills for Exposure in Trauma (ASSET) cadaver-based training, and 12-18 mo later. We hypothesize that residents will better judge their own skill after ASSET than before when compared with evaluator ratings.

Head-camera video recordings of trauma core competency procedures can evaluate surgical resident's technical performance as well as colocated evaluators.

Background: Unbiased evaluation of trauma core competency procedures is necessary to determine if residency and predeployment training courses are useful. We tested whether a previously validated individual procedure score (IPS) for individual procedure vascular exposure and fasciotomy (FAS) performance skills could discriminate training status by comparing IPS of evaluators colocated with surgeons to blind video evaluations.

Methods: Performance of axillary artery (AA), brachial artery (BA), and femoral artery (FA) vascular exposures and lower extremity FAS on fresh cadavers by 40 PGY-2 to PGY-6 residents was video-recorded from head-mounted cameras.

Can hyper-realistic physical models of peripheral vessel exposure and fasciotomy replace cadavers for performance assessment?

Background: Work-hour restrictions have reduced operative experience for residents. The Advanced Surgical Skills for Exposure in Trauma (ASSET) course fills this training gap. Cadaver use has limitations including cost and availability.

Rare case of tibial hemimelia, preaxial polydactyly, and club foot.

A seven-month old female presented with left tibial hemimelia (or congenital tibial aplasia; Weber type VIIb, Jones et al type 1a), seven-toed preaxial polydactyly, and severe club foot (congenital talipes equinovarus). Definitive amputation surgery disarticulated the lower limb at the knee. This case report describes the anatomical findings of a systematic post-amputation examination of the lower limb's superficial dissection, X-rays, and computed tomography (CT) scans.
