Rationale: Portal annular pancreas is a rare anatomic variation, where the uncinated process of the pancreas connects with the dorsal pancreas and the pancreas tissue encases the portal vein (PV), superior mesenteric vein (SMV) or splenic vein (SV). Malignancies are quite uncommon in the patients, who have an annular pancreas especially portal annular pancreas. Ectopic common hepatic artery and...

Mycotic pseudoaneurysm of the ascending aorta is rare in patients undergoing coronary artery bypass graft (CABG) and usually caused by staphylococcus aureus. We describe a patient with a mycotic pseudoaneurysm of the ascending aorta at the proximal vein graft anastomosis site after CABG. Culture from the sinus tract of the sternum and from the aneurysm sac was Klebsiella pneumoniae. Surgical te...

We report on a rare case of blunt traumatic hepatic arteriovenous fistula arising from a pseudoaneurysm in a 35-year-old woman. Transarterial embolization was performed with n-butyl-2-cyanoacrylate, under inflow control with loose coil packing within the pseudoaneurysm and outflow control by balloon occlusion of the hepatic vein. A promising therapeutic outcome was achieved without any serious ...

Posttraumatic external carotid artery pseudoaneurysm with arteriovenous fistula is a rare condition. An 8-year-old child presented with painful pulsatile swelling in the preauricular region following a penetrating glass shrapnel injury. Detailed evaluation showed distal external carotid artery pseudoaneurysm with fistula, which was draining into the retromandibular vein. Endovascular treatment ...

CONTEXT Various techniques for reconstruction after superior mesenteric-splenic-portal vein confluence resection during pancreaticoduodenectomy have been introduced. A certain kind of vascular grafting may be necessary especially when long segmental resection of superior mesenteric-splenic-portal vein confluence is required. CASE REPORT We herein report the cases of two patients who underwent...

BACKGROUND Meso-Rex bypass (MRB) surgery is being increasingly used to treat chronic prehepatic portal hypertension secondary to extrahepatic portal vein thrombosis (EPVT) and cavernous transformation (EPVCT) in children. Rather than using the internal jugular vein (IJV, the traditional venous graft), we used an autogenous splenic vein segment graft for MRB. MATERIAL/METHODS We examined 25 ch...

Umbilical and supraumbilical catheter insertion is a common procedure performed in the NICU. It is a safe and usually easy procedure devoid of serious mishaps, morbidity and mortality. Complications such as hemorrhage, infection, hernia, evisceration, omphalitis, portal vein thrombosis and portal hypertension may occur after umbilical catheter insertion. Other uncommon and rare complications re...

1. Hyposensitivity to vasopressin is a well-documented phenomenon in animals with portal hypertension and patients with cirrhosis subjected to haemorrhage. Excessive formation of nitric oxide is at least partly responsible for the vascular hyporesponsiveness to vasoconstrictors observed in experimental portal hypertension or in rats with haemorrhagic shock. This study investigated whether addit...

Visceral artery pseudoaneurysm and arteriovenous fistula following penetrating abdominal injuries is a rarely observed complication. Presently described is the case of a 44-year-old male admitted to the hospital after having previously experienced penetrating abdominal trauma. The patient had developed a pseudoaneurysm in the superior mesenteric artery and an arteriovenous fistula between the s...

Limited evidence-based protocols exist regarding the management of venous pseudoaneurysms. Cases reports have documented surgical treatments including endovascular coil embolization or suture ligation in the setting of hemodynamic stability. Depending on the location of the venous injury, a more conservative approach to a stable pseudoaneurysm may be advantageous. This report describes a case o...
