1b, thin arrow), a varicose periumbilical vein (Fig. 1b, thick arrow), and a dilated epigastric vein. The distension of the left portal vein had formed a portosystemic shunt and periumbilical vein dilatation (Fig. 1c) on the abdominal wall. These collateral vessels communicated with the bilateral external iliac veins. Abdominal vein dilatation can be caused by vessel obstruction, for example, obstruction of the inferior vena cava. Furthermore, portal hypertension associated with liver cirrhosis can present as a dilated vein on the surface of the click here abdominal wall; this is called caput medusae. To distinguish the cause of the abdominal vein dilatation, the direction of the blood flow in
the vein can be determined by applying pressure to the prominent vein. Blood flows toward the legs when caput buy Paclitaxel medusae sign is present, but it flows in the opposite direction when the inferior vena cava is obstructed. CT scanning or color Doppler ultrasonography can assist in the differential diagnosis.
The caput medusae sign appears when portal hypertension forces the blood flow backward from the left portal vein. Blood returns to the periumbilical systemic veins in the abdominal wall through the paraumbilical veins in the falciform ligament. Adverse events associated with caput medusae sign, including life-threatening hemorrhages from the paraumbilical veins, have been reported previously. These are rare, but when it occurs, direct compression or suture ligation should be considered. If focal treatment cannot be tolerated, specific interventions, such as transjugular intrahepatic portosystemic shunt or an embolization, crotamiton can be considered. In addition, stabilization of the vital signs and the correction of coagulopathy are required. “
“A 61-year-old woman was referred from a local clinic for treatment of a gastric submucosal tumor found during upper gastrointestinal
endoscopy. The lesion had been observed for 18 months and an increase in size and surface ulceration were noted (Figure 1A). The patient had no symptom of dyspepsia, abdominal pain, weight loss or melena. Previous test for H. pylori was negative. Endoscopic ultrasound with a miniprobe (SP-702, Fujinon, sonoprobe) showed that the lesion, 1.0 cm in size, was hypoechoic, homogeneous with indistinct margin originating from the submucosal layer without musclularis propria layer involvement (Figure 1B). Endoscopic submucosal dissection (Figure 1C) was performed for complete removal of the lesion. Upon histological examination, the lesion was composed of proliferative spindle cells, small vessels and marked eosinophils infiltration involving the mucosal and submucosal layers (Figure 2). A diagnosis of inflammatory fibroid polyp was made. Gastric inflammatory fibroid polyp is a rare and benign disorder accounting for 0.1% of gastric polyps. The antrum is the most common involved site.
