External Ear and Submandibular Extracranial Arteriovenous Malformation: A Case Report | Chapter 14 | New Visions in Medicine and Medical Science Vol. 7

Arteriovenous malformation (AVM) are caused by failure of primitive arteriovenous channels to regress during fetal development. Extracranial AVM is a rare entity. The aim of this descriptive study is to show the progressiveness of an extracranial AVM of a patient over the course of 20 years. A 34 years old male, initially presented with a soft compressible at the left ear pinna since age of 15 years old. 6 years later he developed another soft compressible swelling at the left cheek. Further investigations showed arteriovenous malformation from branches of the left external carotid artery with draining veins from left external jugular vein. A suggested treatment of embolization and left pinectomy made the patient worried of disfigurement and he defaulted treatment from Hospital Kuala Lumpur. Last year he had one presentation of blood spurting from his left ear pinna which needed medical attention at Hospital Shah Alam. CT Angiography (CTA) was done and the extent of the disease recorded which involved the terminal branches of external carotid artery for the external ear AVM, which are maxillary artery and superficial temporal artery as well as facial artery for the submandibular AVM, all draining into the external jugular vein. Currently there are more protruding vessels seen at the back of his ear and he was advised to revisit Hospital Kuala Lumpur for treatment option. It is a sign of persistence and progressiveness of his disease. Author was unable to find reported incidence of external ear and submandibular AVM in the same individual, however there was a reported case of infratemporal and parotid AVM. The affected branches were different however it shows there are literature of more than 1 extracranial AVM on the same side but scarce. Follow up of this patient may provide useful in monitoring further vessel dilatation or new AVM cranially or caudally from the branches of the external carotid artery.

Glass Fragment-Induced Vertebral Artery Injury: A Unique Case Report | Chapter 6 | Current Progress in Medicine and Medical Research Vol. 4

 This unit discuss about a case report for the administration of vertebral artery (VA) injuries developing from trauma to the narrow connector, with a specific devote effort to something a unique case including an 82-year-old man. The patient bestowed with stinging neck injuries created by broken bottle, leading to VA harm and the formation of a pseudoaneurysm. We did interventional angiography, obstructed the right VA, and then suffered neck surgery cause it was possible that harsh bleeding had occurred all the while the exploration encircling the pseudoaneurysm. We did the surgical process to remove the glasses five days later the embolisation. There was no bleeding all along and after the operation, and the patient was ridicule- charged outside any complication. Based on the angiography results and the perceptibility of the injured VA in the operating field, the physician can choose the appropriate treatment plan.

Significance of Extra Hepatic Portal Vein Variations in Hepatopancreatic Surgeries | Chapter 3 | Highlights on Medicine and Medical Science Vol. 3

 Introduction: When performing pancreas and duodenum surgeries, it is critical to understand the variations in the portal vein's path. It can also be used to treat traumatic mesentery rupture. Awareness of portal vein variations is critical in surgical resection and transplantation, especially during pretreatment planning, to reduce the complication rates of the surgical and radiological treatments. Furthermore, an in-depth understanding of portal vein variations is essential in determining the technical feasibility of surgical interventions such as liver transplantation, portal vein embolization prior to hepatectomy, and postoperative care. The purpose of this study is to examine the anatomical variations of the portal vein, correlate the findings with clinical problems, and provide a good ontological explanation. Materials and Methods: Twenty-four cadavers embalmed in 10% formalin were obtained from the department of anatomy and dissected for this study. Variations were meticulously cleaned and photographed. Among the variations observed were the formation of the portal vein by the confluence of the superior mesenteric, inferior mesenteric, and splenic veins (1 case), as well as the inferior mesenteric vein terminating in the superior mesenteric vein (6 cases). Conclusion: The purpose of this study was to determine the approximate percentage of incidence of major variations in portal vein formation. By being aware of such variations prior to major abdominal procedures, it is possible to avoid severe intraoperative hemorrhage.
