To reverse or not to reverse the radial artery in coronary artery bypass graft surgery? Histopathologic concerns and media thickness.

Background And Aims: Radial artery (RA) is a popular coronary artery bypass grafting (CABG) conduit. The challenging issue is vasospasm. A few studies are available on histopathological differences between RA's proximal and distal ends.

Coronary artery bypass and carotid endarterectomy with mild hypothermia.

The approach to treatment in patients with both coronary artery disease and major carotid disease is controversial. We analyzed our results of concomitant coronary artery bypass and carotid endarterectomy. Twenty-three patients aged 58 years or older underwent elective concomitant coronary artery bypass and carotid endarterectomy with mild hypothermia (32°C).

Is severe electrolyte imbalance a contraindication for heart transplant?

Owing to the increasing numbers of patients with end-stage congestive heart failure awaiting heart transplant and the limited number of suitable donor organs, a decrease in stringency of donor criteria has become widely accepted over the last decade. Here, we present a case of a heart donor with severe electrolyte imbalance, specifically severe hypokalemia, and severe hypernatremia. Despite this, heart transplant was a success, and the recipient was discharged from the hospital in good general condition.

Effects of the arteriovenous fistula on pulmonary artery pressure and cardiac output in patients with chronic renal failure.

Introduction: Access to the vascular system is necessary in patients with chronic renal failure planned to undergo dialysis. One of the complications of end-stage renal disease patients is pulmonary hypertension (PHT). Temporary arteriovenous access closure and successful kidney transplantation causes a significant fall in cardiac output and pulmonary artery pressure (PAP), indicating the possibility that excessive pulmonary blood flow is involved in the pathogenesis of the disease.

Non iatrogenic paediatric vascular trauma of the extremities and neck.

Aim: Vascular trauma in children is uncommon. Considering the complexity of these injuries, we have tried to determine their demographic data, the different factors changing their outcome, the different modalities of management, and their outcomes.

Patients And Methods: We reviewed the medical records of 52 pediatric patients of less than 15 years f age for about ten years (1996 to 2006) .
