A young male underwent decompressive craniotomy for an intracerebral bleed. A right-sided subclavian central venous catheter was placed in the operating room after induction of anesthesia. Postoperatively, he was shifted to Intensive Care Unit (ICU) for mechanical ventilation due to low Glasgow coma scale. He had an episode of severe agitation and straining on the tracheal tube in the evening same day. On the 2nd postoperative day in ICU, his airway pressures were high, and chest X-ray revealed massive pleural effusion on right side...

OBJECTIVE: Endovenous thermal ablation has become the primary modality of treatment for patients with venous insufficiency. Previous literature has provided reviews of radiofrequency ablation (RFA) or endovenous laser ablation (EVLA) that mostly focus on the great saphenous vein (GSV) and small saphenous vein (SSV). Data with an extended review including the anterior accessory saphenous vein (ASV) and perforator veins (PVs) have been limited. This study examines the treatment of venous insufficiency with RFA and EVLA of these multiple veins to identify clinical and demographic predictors of both the early success and thrombotic complications of endovenous thermal ablation...

Venous insufficiency of the lower limb is a common disease. Diagnosis is based on symptoms, clinical findings and duplex ultrasound. Consideration and planning of invasive treatment cannot be performed without ultrasound. Vast majority of invasive treatments in superficial venous insufficiency can be done by ultrasound-guided endovenous methods with local anesthesia. Thermoablation (laser of radiofrequency) is the first-line treatment. There are promisisng endovenous methods for treatment of deep venous obstruction in selected cases...

OBJECTIVE: Thermoablation has been replacing conventional surgery in the surgical treatment of great saphenous vein (GSV) reflux in patients with lower limb varicose veins; however, thermoablation is expensive. Intravenous electrocoagulation (EC) may, selectively and safely, cause necrosis of the GSV wall, but the clinical results have never been studied. The objective of this study was to compare EC and radiofrequency ablation (RFA) in the treatment of GSV insufficiency, considering efficacy, complications, and effect on quality of life...

Static apnea provides a unique model that combines transient hypertension, hypercapnia, and severe hypoxemia. With apnea durations exceeding 5 min, the purpose of the present study was to determine how that affects cerebral free-radical formation and the corresponding implications for brain structure and function. Measurements were obtained before and following a maximal apnea in 14 divers with transcerebral exchange kinetics, measured as the product of global cerebral blood flow (duplex ultrasound) and radial arterial to internal jugular venous concentration differences (a-vD)...

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...
