It is essential to identify any variant anatomy prior to surgery as this could have a drastic effect on surgical planning. We describe a case in which two vascular irregularities, an Arc of Buhler and celiac stenosis, were identified on angiogram after completion of a pancreaticoduodenectomy. While there could have been catastrophic results from his surgery in the setting of celiac stenosis, th...

Key Points: • PSVA/MVD syndrome is a complex polygenic trait causing hepatic portal hypoperfusion. PSVA and MVD usually cannot be distinguished by liver biopsy alone. • PSVA associates with historical & clinicopathologic features lacking in MVD: low RBC MCV, cholesterol, BUN, creatinine, urine SG, and ammonium biurate crystalluria and uroliths • PSVA associates with low Protein C activity (100%...

Vascular anomalies are localized defects in the vasculature that may or may not be present at birth. There are many types of vascular anomalies with different aetiology and clinical picture and, therefore, require the combined expertise of medical, radiological, and surgical specialities for its diagnosis and management. The term "haemangioma" is used as a common generic label to incorporate al...

Fenestration of the vertebral artery is a rare vascular anomaly that has been observed at autopsy and on angiography. It is most commonly seen in the extracranial segments of the vertebral artery. This congenital anomaly can arise during multiple different stages of embryological development of the vertebral artery. The clinical significance is unclear, but multiple studies have reported associ...
