Portal Vein Embolization Followed by Liver Resection versus Liver Resection Alone: a Comparison of Liver Regeneration Dynamics.

Background/aims: Portal vein embolization (PVE) is an accepted procedure, which, by redirecting portal vein flow toward specific hepatic segments, is able to pre-operatively increase the volume of the future liver remnant (FLR). The consequent reduction of liver dysfunction risk enables to extend the number of pa tients eligible for major hepatic resection. This study aims at comparing liver regeneration dynamics and long-term volumetric recovery after major hepatic re section preceded by PVE versus major hepatic resec tion not preceded by PVE.

Walking unsteadily: a case of acute cerebellar ataxia.

Acute cerebellar ataxia is an infrequent neurological syndrome in adults especially if complicated by additional neurological deficits. We report the case of a 69-year-old woman who presented with sudden onset of left facial droop, dizziness, slurred speech and impaired balance. Her medical history included paroxysmal atrial fibrillation and a sigmoid diverticular abscess treated with ciprofloxacin and metronidazole.

Randomised comparison of complications from three different permanent central venous access systems.

Principles: We present a prospective randomised trial comparing complications from three different permanent central venous access systems (PCVAS).

Methods: The PCVAS trial groups were I, polyurethane ChemoSite (AutoSuture); II, polyurethane Port-a-Cath (Pharmacia-Upjohn); and III, silicone Port-a-Cath. The PCVAS were inserted under local anaesthesia by direct puncture of the subclavian vein, using the Seldinger technique.

Localized hepatic ischemia after liver resection: a prospective evaluation.

Objective: To prospectively assess the frequency, severity, and extension of localized ischemia in the remaining liver parenchyma after hepatectomy.

Background: Major blood loss and postoperative ischemia of the remnant liver are known factors contributing to morbidity after liver surgery. The segmental anatomy of the liver and the techniques of selective hilar or suprahilar clamping of the Glissonian sheaths permit identification of ischemia on the surface of the corresponding segments for precise section of the parenchyma.
