Successful anticoagulation with fresh frozen plasma for cardiopulmonary bypass in a patient with heparin resistance: a cautionary tale.

Heparin resistance (HR) is an increasingly common occurrence due to a greater awareness of the benefits of antithrombosis prophylaxis in hospitalised patients with low molecular weight and unfractionated heparin. Furthermore as more high-risk patients with prior heparin exposure undergo cardiac surgery we can expect to encounter more such cases. Adequate anticoagulation is essential for the safe conduct of any operation requiring cardiopulmonary bypass and is usually achieved with systemic heparinisation.

Synchronous sclerosing haemangiomas of the lung: an unusual presentation of a rare tumour.

Pulmonary sclerosing haemangioma  is a rare lung tumour with a preponderance for Asian oriental women. Typically a well-circumscribed, solitary lesion with benign characteristics, there are concerns of malignant potential including regional lymph node metastases. Four histological subtypes exist.

Contemporary surgical management of advanced end stage emphysema: an evidence based review.

Emphysema is a progressive unrelenting component of chronic obstructive pulmonary disease and a major source of mortality and morbidity globally. The prevalence of moderate to severe emphysema is approximately 5% in Malaysia and likely to increase in the future. Hence advanced emphysema will emerge as a leading cause of hospital admission and a major consumer of healthcare resources in this country in the future.

Simultaneous aortic valve and arch replacement with bilateral nephrectomy for massive polycystic kidney disease, aortic regurgitation and dissecting aneurysm.

Aneurysmal dissection of the ascending aorta and arch may be associated with polycystic kidney disease. We report a case of massive polycystic kidneys leading to respiratory and gastrointestinal embarrassment in combination with aneurysmal dilatation of a chronic arch dissection managed by simultaneous bilateral nephrectomy and arch replacement.

Idiopathic primary chylopericardium with associated chylothorax following coronary artery surgery--successful conservative treatment.

A 58-year-old Asian male underwent an uneventful triple coronary bypass that included a pedicled left internal mammary artery (LIMA) graft. On the third postoperative day, following resumption of full oral intake he developed a high output left-sided chylothorax. Initial therapy with a medium chain trigylceride diet and intercostal drainage showed no improvement.

Mitral and tricuspid valve surgery in homozygous sickle cell disease: perioperative considerations for a successful outcome.

Homozygous sickle cell disease (SCD) presents a multitude of challenges in patients undergoing cardiac surgery with cardiopulmonary bypass. Special consideration must be made in such patients and routine practice modified to prevent hypoxia, hypothermia, acidaemia and low-flow states which may potentially trigger a fatal sickling crisis perioperatively. We discuss several perioperative management strategies including a preoperative exchange transfusion, high flow normothermic bypass and warm blood cardioplegia that was utilized in a woman with homozygous SCD who underwent a successful double valve procedure.

Aortic valve replacement with simultaneous chest wall reconstruction for radiation-induced sarcoma.

Sarcomas, a rare complication of radiotherapy for breast carcinoma, have a poor prognosis. We describe a lady with previous mantle radiotherapy exposure, who developed a radiation-induced chest wall sarcoma. She underwent simultaneous aortic valve replacement (AVR) for severe aortic stenosis and excision of the sarcoma.
