Role of Computed Tomography Perfusion in Patients with Liver Cirrhosis and Hepatocellular Carcinoma.

Background: There is a lack of data on computed tomography (CT) perfusion parameters in patients with cirrhosis and the vascular changes that occur with increasing severity of cirrhosis, as well as changes that can occur in the remote/background liver parenchyma when hepatocellular carcinoma (HCC) develops. This study aimed to evaluate the association between CT perfusion parameters in the background liver parenchyma in cirrhotic patients with and without HCC.

Methods: This prospective study comprised consecutive patients with cirrhosis with or without HCC.

Endovascular Management of Lower Limb Arteriovenous Fistula Presenting 8 Years After Gunshot Injury.

Trauma is a common cause of arteriovenous fistula resulting from iatrogenic or penetrating injuries such as gunshot wounds, stab injuries, and so on. Endovascular management using stent grafts is a minimally invasive method to manage these complex vascular injuries. We present a case report of a young male patient who presented to us with complaint of progressively increasing swelling in the left lower limb 8 years after gunshot injury to that limb.

Diagnostic Value of Glypican3, Heat Shock Protein 70 and Glutamine Synthetase in Hepatocellular Carcinoma Arising in Cirrhotic and Non-Cirrhotic Livers.

Background And Objectives: Histopathological distinction of various nodular lesions in liver with sufficient sensitivity and specificity is a challenge even in an expert set up. The panel of immunohistochemical markers composed of glutamine synthetase (GS), Glypican3 (GPC3) and heat shock protein 70 (HSP70) was recommended by the International Consensus Group for Hepatocellular Neoplasia group for the differentiation of high grade dysplastic nodule and early hepatocellular carcinoma (HCC). The panel has been extensively validated in the western population.

Iatrogenic life-threatening pseudoaneurysms of extracranial internal carotid artery after fine-needle aspiration of cervical lymph nodes: report of two cases in children.

Two children younger than 10 sought care for large, tense pulsatile swelling in the neck after fine-needle aspiration of cervical lymph nodes that resulted in severe respiratory distress. Computed tomographic angiography confirmed the presence of large pseudoaneurysms that caused a mass effect, leading to compression of surrounding vessels and airway. Pseudoaneurysms were successfully treated by coil embolization in one patient and surgical ligation of the internal carotid artery in the other.
