Iatrogenic venous pseudoaneurysm (VP) formation after venipuncture is rare. This report showed 2 cases of VP following venipuncture, and VPs were resected surgically. A 58-year-old woman and a 56-year-old woman developed a soft antecubital mass after blood sampling from the basilic veins. One patient had the sensory disturbance of forearm. The mass was diagnosed as a VP with thrombus by duplex ultrasound and magnetic resonance imaging. The aneurysm was resected completely, and the sensory disturbance of the patient was improved...

An arteriovenous fistula is an abnormal connection between the arterial and venous systems. In the literature, there are well-described ultrasound findings of iatrogenic arteriovenous fistula as a potential complication from percutaneous transarterial or transvenous procedures. The most important sign is direct visualization of the fistula in the place of the access site. It is necessary to look for secondary signs of arterialization of the veins, which can suggest a diagnosis of an arteriovenous fistula. However, the accuracy and diagnostic quality of duplex scanning in the diagnostics of a congenital or spontaneous arteriovenous fistula of the head and neck area in adults have been poorly described in the literature...

BACKGROUND: Routine radiofrequency ablation (RFA) of an incompetent perforator vein (IPV) using the standard treatment protocol at 85°C has a treatment time of 6 minutes. To make treatment time more efficient, we sought to determine the effect of a shortened protocol for radiofrequency stylet (RFS) ablation by comparing the early success using three different temperatures: 85°C, 90°C, and 95°C. METHODS: A retrospective study examined 642 procedures of IPV closures in 255 patients with varying degrees of venous insufficiency treated with RFA from 2009 to 2015...

Children are particularly at risk for stroke in the neonatal period. Neonatal hemorrhagic stroke is rarer than ischemic stroke. The incidence is 40.7/100 000 live births. Hemorrhagic stroke is caused by a disruption in venous drainage usually due to local thrombosis. As a result of the nonspecific clinical symptoms in this age group, diagnosis is usually made too late. The only relatively specific symptom is a cerebral seizure during the first week of life. Therefore, stroke should be ruled out by diagnostic imaging in the case of any seizure in the first days of life...

BACKGROUND: The majority of iliac venous obstructions occur on the left side, and endovascular therapy has become the first line treatment for this condition. A left common iliac venous stent will protrude into the inferior vena cava (IVC) to some extent, thereby covering the contralateral common iliac vein (CIV) outflow. This may increase the risk of thrombosis of the contralateral iliac vein. The aim of this paper was to determine the rate of, and factors associated with, contralateral lower limb venous thrombosis after stenting, and to evaluate the results of salvage revascularisation...
