Hemorrhagic shock due to ileal varices, a diagnostic challenge.

Gastrointestinal bleeding due to portal hypertension is a major complication in patients with cirrhosis, commonly attributed to esophagogastric varices. However, bleeding from ectopic varices accounts for 5% of variceal bleeding cases and it may occur at lower pressures than esophageal varices. Thus, ectopic varices should be considered in patients with portal hypertension that present with gastrointestinal bleeding lacking evidence of esophagogastric variceal bleeding on upper gastrointestinal endoscopy.

Possible predictors of poor angiogenesis after hematopoietic stem cell autograft for lower limb ischemia.

Introduction: The therapeutic potential of adult stem cells in coronary and peripheral arterial diseases has been proposed in recent years. However, factors possibly predictive of unfavorable angiogenic results have not been clearly identified as yet.

Objectives: Identify candidate predictors of poor angiogenesis, as indicated by need for amputation, after autologous hematopoietic stem cell transplantation for chronic lower limb ischemia.
