Cameron Hassani, Farhood Saremi
The pulmonary veins carry oxygenated blood from the lungs to the heart, but their importance to the radiologist extends far beyond this seemingly straightforward function. The anatomy of the pulmonary veins is variable among patients, with several noteworthy variant and anomalous patterns, including supernumerary pulmonary veins, a common ostium, anomalous pulmonary venous return, and levoatriocardinal veins. Differences in pulmonary vein anatomy and the presence of variant or anomalous anatomy can be of critical importance, especially for preoperative planning of pulmonary and cardiac surgery...

Surgery for the Cranio-vertebral (CV) junction anomalies using top loading subocciput (C0)/C1-C2 screws is difficult and requires high level of skill and expertise. This is because of complex abnormal anatomy in that region and other issues including the instrumentation. Thorough knowledge of the 3D anatomy of the Craniovertebral junction of the patient is essential for favourable outcome. The customised 3D printed model of CV junction region of the patient can be used for studying the anatomy and relationship of vertebral artery to the C1-C2 joint before the actual surgery...

BACKGROUND Surgical treatment of acetabular fracture and the anatomic reconstruction of the hip joint are difficult to achieve due to the complex pelvic anatomy, and surgical training requires a prolonged and steep learning curve. The aim of this study was to evaluate the effects of an applied training course, including cadaveric dissection, for the surgical treatment of acetabular fractures. MATERIAL AND METHODS This retrospective study included 35 patients who underwent surgical treatment for acetabulum fractures between 2012-2016...

Unusual anatomical segmentectomies are technically demanding procedures that require a deep knowledge of intralobar anatomy and surgical skill. In the other hand, these procedures preserve more normal lung parenchyma for lesions located in specific anatomical segments, and are indicated for benign lesions, metastasis and also early stage adenocarcinomas without nodal involvement. A 32-year-old woman was diagnosed of a benign pneumocytoma in the anterior segment of the left-lower lobe (S8, LLL), so we performed a single-incision video-assisted thoracoscopic surgery (SI-VATS) anatomical S8 segmentectomy in 140 minutes under intercostal block...

PURPOSE: Despite advances in medical and surgical care, pancreatic ductal adenocarcinoma remains one of the most locally aggressive neoplastic processes in the abdomen. Unfortunately, most pancreatic adenocarcinomas present late and are unresectable at time of diagnosis. The modified Appleby procedure is a surgical option in patients with locally advanced pancreatic neoplasms of the body and tail with vascular invasion of the celiac trunk. To our knowledge, no radiologic journal has previously reported on the pre-operative evaluation or postoperative imaging findings of such patients...

Liver transplant is considered to be the last-resort treatment approach for pediatric patients with end-stage liver disease. Despite the remarkable advance in survival rates, liver transplant remains an intricate surgery with significant morbidity and mortality. Early diagnosis of complications is crucial for patient survival but is challenging given the lack of specificity in clinical presentation. Knowledge of the liver and vascular anatomy of the donor and the recipient or recipients before surgery is also important to avoid complications...

The axillopectoral muscle is a rarely discussed variant of muscular anatomy of the axilla, with various clinical implications. We report a case of a 7-year-old girl with multiple genetic and developmental abnormalities who presented with asymmetrical right axillary bulging of unknown etiology. MRI demonstrated a small accessory axillary muscle, known as Langer's axillary arch and/or the axillopectoral muscle. Other than soft-tissue asymmetry, the patient experienced no additional related symptoms. However, this is an important variant to be aware of, as it can easily be discovered on imaging and may be a causative agent for various upper extremity symptoms that may resolve with appropriate recognition and surgical intervention...

BACKGROUND: Limited pancreatic resections are increasingly performed, but the rate of postoperative fistula is higher than after classical resections. Pancreatic segmentation, anatomically and radiologically identifiable, may theoretically help the surgeon removing selected anatomical portions with their own segmental pancreatic duct and thus might decrease the postoperative fistula rate. We aimed at systematically and comprehensively reviewing the previously proposed pancreatic segmentations and discuss their relevance and limitations...

Portal vein anatomy and its branching pattern are of utmost importance for surgical planning of complex liver resections, living donor liver transplant and radiological procedures. The division of the vein at the porta hepatis, into the right and left branches is the most common branching pattern. Various branching variations have been described. We report a previously undescribed branching pattern of the right portal vein, where the segment VII vein arises directly from the left portal vein.

The ganglion pterygopalatinum has become a therapeutic target to treat various pain syndromes in recent years. It is located in the fossa pterygopalatina, and the fissura pterygomaxillaris is the main access to surgically approach this structure. Recently, the neuromodulation of the ganglion pterygopalatinum by microstimulator implantation has become the first therapeutic line in refractory cluster headache treatment. This invasive technique is performed transorally through the fissura pterygomaxillaris, and is limited by the size of the implantation device, which requires an opening of at least 2 mm...

REVIEW
Minhao Hu, David Wattchow, Dayan de Fontgalland
The landscape of surgical anatomy education is progressively changing. Traditional methods, such as cadaveric dissection and didacticism are being increasingly phased out in undergraduate courses for multimodal approaches incorporating problem-based learning, radiology and computer-based simulations. Although effective at clinically contextualizing and integrating anatomical information, these approaches may be a poor substitute for fostering a grasp of foundational 'pure' anatomy. Dissection is ideal for this purpose and hence remains the cornerstone of anatomical education...

There is little current literature on the augmented-pressure distal colostogram, the single most important diagnostic study performed in boys with imperforate anus prior to definitive repair. Accurate understanding of the anatomy of the anorectal malformation including an associated fistulous communication between the rectum and the urogenital tract is essential for optimal surgical management. Specifically, the position of the rectal pouch and recto-urinary fistula relative to posterior sagittal structures of the perineum, especially the sacral spine, dictates the operative approach...

The sick lobe hypothesis provides the basis for a lobar approach in radiology, pathology, and surgical treatment of breast cancer. This approach aims to remove the tumor together with the surrounding field of genetic aberrations. Detailed preoperative lobar imaging that properly maps the disease and assesses its extent guides the parenchymal resection. Integration of our knowledge of breast anatomy and pathology with the results of preoperative radiological mapping is critical in assessing the eligibility of patients with multifocal and/or multicentric breast cancer for breast conservation treatment...

Although interpatient variations in the course and anatomy of extracranial internal carotid arteries (EICAs) have been described previously, intrapatient variability is rarely cited in the literature. Distance between EICAs and the pharyngeal wall is an important determinant of vascular injury risk. A retropharyngeal EICA has crucial implications in patients undergoing pharyngeal procedures, and important in otorhinolaryngology and emergency medicine. Surgical exploration without identification of anatomical landmarks, or emergent intubation in the emergency room poses high risk for EICA injury...
