Haemorrhagic peritonitis as a late complication of echocardiography guided pericardiocentesis.

Clinically significant pericardial effusion is an uncommon complication after cardiac surgery. Pericardiocentesis can be performed either through a mini-sternotomy or under echocardiography guidance. Echocardiography guidance is a relatively safe procedure and it avoids the need for another general anaesthetic. However, in this post cardiac surgical patient echocardiography guided pericardiocentesis was complicated several days later by haemorrhagic peritonitis.

Improved outcome with organs from carbon monoxide poisoned donors for intrathoracic transplantation.

BACKGROUND: The success of intrathoracic organ transplantation has lead to a growing imbalance between the demand and supply of donor organs. Accordingly, there has been an expansion in the use of organs from nonconventional donors such as those who died from carbon monoxide poisoning. We describe our experience with 7 patients who were transplanted using organs after fatal carbon monoxide poisoning. METHODS: A retrospective study of the 1,312 intrathoracic organ transplants between January 1979 and February 2000 was completed. Seven of these transplants (0.5%) were fulfilled with organs retrieved from donors after fatal carbon monoxide poisoning. There were six heart transplants and one single lung transplant. The history of carbon monoxide inhalation was obtained in all of these donors. RESULTS: Five of 6 patients with heart transplant are alive and well with survival ranging from 68 to 1,879 days (mean, 969 +/- 823 days). One patient (a 29-year-old male) died 12 hours posttransplant caused by donor organ failure. The patient who had a right single lung transplant did well initially after the transplant, but died after 8 months caused by Pneumocystis carinii pneumonia. All those recipients who were transplanted from carbon monoxide poisoned donors and ventilated for more than 36 hours, survived for more than 30 days. Moreover, these donors were assessed and optimized by the Papworth donor management protocol. CONCLUSIONS: Carbon monoxide poisoned organs can be considered for intrathoracic transplantation. In view of the significant risk of donor organ failure, a cautious approach is still warranted. Ideally, the donor should be hemodynamically stable for at least 36 hours from the time of poisoning and on minimal support. A formal approach of invasive monitoring and active management further improves the chances of successful outcome.

Cryofibrination: did it really happen?

Cryofibrin precipitation is a phenomenon which has only recently been described, although it might have been present since the advent of membrane oxygenators for cardiopulmonary bypass procedures. The deposition of the cold-reactive protein, cryofibrin, causes progressive occlusion of the heat-exchanger part of the cardiopulmonary circuit, thus leading to a high pressure-drop phenomenon. We describe our experience with a few cases in which the cryofibrination phenomenon developed while using the 'Avecor-Affinity Medtronic' membrane oxygenator.

Pulmonary thromboendarterectomy.

Pulmonary thromboendarterectomy (PTE) provides a curative alternative to the otherwise fatal condition of chronic thromboembolic pulmonary hypertension (CTEPH). However, the condition is under-diagnosed due to a lack of awareness. An acceptable operative mortality of around 10% and long-term survival exceeding medical therapy or transplantation makes PTE a favourable choice for the treatment of CTEPH. Outcome is further optimised if the disease is diagnosed early and patients referred to specialised centres. An increase in the number of surgical procedures will also contribute to lower the mortality associated with this condition.
