Craniomaxillofacial congenital anomalies comprise approximately one third of all congenital birth defects and include deformities such as alveolar clefts, craniosynostosis, and microtia. Current surgical treatments commonly require the use of autogenous graft material which are difficult to shape, limited in supply, associated with donor site morbidity and cannot grow with a maturing skeleton. Our group has demonstrated that 3D printed bio-ceramic scaffolds can generate vascularized bone within large, critical-sized defects (defects too large to heal spontaneously) of the craniomaxillofacial skeleton...

INTRODUCTION: We are a reporting on the indications, techniques, and limitations of robotic surgery in the management of renal stones disease. Robotic surgery is a good tool to manage large kidney and ureteral stones, particularly in patients with anatomic anomalies. We describe three techniques in managing staghorn kidney stones: robotic anatrophic nephrolithotomy, robotic pyelolithotomy, and robotic nephrolithotomy. MATERIAL AND METHODS: Robotic pyelolithotomy (RP) is ideal for patients with large renal pelvis and partial staghorn stone with a wide extra-renal pelvis...

REVIEW
J M Lieb, F J Ahlhelm
CLINICAL ISSUE: Agenesis of the corpus callosum is reported to have an incidence of about 1:4000 live births. In 30-45% of cases, genetic etiologies can be identified, e. g., 10% chromosomal anomalies and 20-35% genetic syndromes. Environmental factors like fetal alcohol syndrome are also known to be prone to callosal agenesis. Callosal agenesis can be complete or partial and can be isolated or associated with other central nervous system (CNS) anomalies (e. g., cortical developmental disorders, callosal lipoma, intracranial cysts) or extra-CNS anomalies (e...

The persistent sciatic artery (PSA) is a remnant of the fetal circulatory system that is preserved in less than 0.1% of the population. Up to 60% of patients with this vascular anomaly will go on to development of a PSA aneurysm (PSAA), which can produce a variety of symptoms including neuropathy, claudication, and acute limb-threatening ischemia. Historical management is by open operation and interposition grafting, which can be highly morbid. We describe successful management of a large, symptomatic PSAA by endovascular stent-grafting with intermediate term follow-up...

Case summary: A 6-month-old female cat with a history of chronic regurgitation presented with weight loss. CT angiography (CTA) showed severe constriction of the oesophagus due to an aberrant right subclavian artery and Kommerell's diverticulum. The cat was surgically treated and remained clinically normal. More than 1 year after surgery, the general condition of the cat was stable and body weight had increased. Relevance and novel information: This case report describes the clinical findings and surgical management of a cat diagnosed with severe oesophageal constriction caused by an aberrant right subclavian artery with Kommerell's diverticulum (markedly dilated origin of the aberrant right subclavian artery), which are rare vascular anomalies in veterinary medicine and specifically in cats...

BACKGROUND: The anatomic variations of the visceral arteries are not uncommon. The liver arterial blood supply shows 50% variability between humans, with the most common anatomy being one hepatic artery arising from the celiac trunk and one pancreatico-duodenal arcade between the celiac trunk and the superior mesenteric artery. Occlusion of one artery are mostly asymptomatic but may become clinically relevant when surgery of the liver, bile duct or the pancreas is required. If these pathologies are not reversible, an oncologic pancreatic head resection cannot be performed...

Three entire, domestic, shorthair male cats (age range: 3 months to 5 years) were referred because of regurgitation. Megaoesophagus attributable to aberrant right subclavian artery, originating from the aorta at the level of the fourth intercostal space, was diagnosed in all cats using thoracic radiography and CT angiography. One cat had concurrent patent ductus arteriosus with a normal aortic arch. Three-dimensional volume-rendered CT images were used to assess the malformations and to plan surgery for the treatment of the vascular anomalies...

The placenta is a complex organ that influences prenatal growth and development, and through fetal programming impacts postnatal health and well-being lifelong. Little information exists on placental pathology in the presence of congenital heart disease (CHD). Our objective is to characterize the placenta in CHD and investigate for distinctions based on type of malformation present. Placental pathology from singleton neonates prenatally diagnosed and delivered at > 37 weeks gestation was analyzed. Placental findings of absolute weight, placental weight-to-newborn birth weight ratio, chorangiosis, villus maturity, thrombosis, and infarction were recorded and analyzed based on four physiological categories of CHD: (1) single ventricle-aortic obstruction, (2) single ventricle-pulmonic obstruction, (3) two-ventricle anomalies, and (4) transposition of the great arteries (TGA)...

INTRODUCTION: Popliteal artery entrapment is an uncommon syndrome, caused by extrinsic compression of the popliteal artery by muscular or tendinous structures. It occurs mainly in young individuals, with no atherosclerostic risk factors, and a mean age of presentation of 20 to 40 years, and has higher prevalence in males (83% of patients). Clinical presentation depends on the degree of arterial lesion, the most common being intermittent claudication, with critical ischemia being frequent...

Aneurysms of the subclavian artery are rare phenomena that have the potential for limb and life-threatening complications. Delayed diagnosis increases the risk of life-threatening complications or at the very least may result in a detrimental effect to both functional capacity and quality of life; primary care offers a vital opportunity to screen for such rare vascular complications and should be a consideration in all patients with evolving peripheral nerve or vascular symptoms with a history of localized clavicular trauma...

Congenital anatomic anomalies and variations are frequent in the thoracic outlet and may be associated with clinical symptoms. Arterial thoracic outlet syndrome (TOS) is characterized by subclavian artery compression and vascular pathology, almost always in the presence of a bony abnormality. We describe here a patient with arterial thromboembolism following a fall on the outstretched arm, who was found to have subclavian artery stenosis and post-stenotic dilatation in the absence of a bony abnormality. Surgical exploration revealed a previously undescribed anomaly in which the subclavian artery passed through the costoclavicular space in front of the anterior scalene muscle, where it was subject to bony compression between the first rib and clavicle...
