Early postoperative thrombosis of an aortic bioprosthetic valve: should anticoagulation be patient specific?

Optimal antithrombotic recommendations for patients following bioprosthetic aortic valve replacement have yet to be decided. Current guidelines present conflicting opinions and are based on historical studies, which are limited by their design. We review comparative studies investigating differing thromboprophylactic regimes and outcomes for bioprosthetic aortic valve replacement.

Postdischarge complications: what exactly happens when the patient goes home?

Economic implications favouring early discharge have led to an ever increasing demand to send patients home for recuperation. Patients are now routinely released on their fourth postoperative day, thereby making postdischarge complications harder to record and audit. We set about the use of a structured questionnaire to evaluate the incidence of all postdischarge complications requiring therapy within the first six weeks of convalescence. Over a 24-month period, 382 patients were questioned following cardiac surgery. Of these patients, 72% had an uneventful postoperative recovery, however, 17% needed treatment from their general practitioner, 6% were readmitted, 5% required district nurse treatment and 1% called the National Health Service advice line (NHS direct). Furthermore, despite the fact that 28% of discharges required further medical intervention in the majority of cases, cardiothoracic clinicians were not aware of complications requiring treatment. The auditing of these complications has resulted in changes in our surgical practice leading to a reduction in postoperative complications. Structured questionnaires are a useful tool in allowing improvement in surgical technique. They can be used by all members of the cardiothoracic team regardless of their grade and enable a methodical and reproducible assessment of all discharged patients.

Repair of spontaneous right ventricular rupture following sternal dehiscence. A novel technique.

Spontaneous rupture of the right ventricle during the early postoperative period is a serious and potentially lethal complication. The inherent friability of the ventricular tissue makes repair difficult since myocardium is frequently weakened by infarction, mediastinitis or trauma caused by an unstable sternum or broken sternal wires. We present a novel yet simple technique for repairing the ruptured anterior wall of the right ventricle in a patient three weeks following coronary artery bypass surgery.

Malignant pleural effusion in the presence of trapped lung. Five-year experience of PleurX tunnelled catheters.

Malignant pleural effusions in the presence of trapped lung remain notoriously difficult to treat. Various methods exist ranging from minimally invasive procedures including repeated needle thoracocentesis to the need for a formal surgical procedure such as placement of a pleuroperitoneal shunt and even thoracotomy and decortication. Controversy exists as to what is the optimum treatment for this condition. Any planned treatment should balance the therapeutic benefit provided against convalesce for a disease with a limited life expectancy. Patients should not spend a significant proportion of their remaining life span recovering from palliative procedures. In a series of patients with malignant pleural effusion the medial survival time was 20 weeks, with 30 days and 1 year mortality rates of 12.8% and 83.6%, respectively. We describe our five-year experience with the use of indwelling PleurX catheters in patients with malignant pleural effusions in the presence of confirmed trapped lung on radiological or VATS investigation. Patient health related quality of life was investigated by telephone questionnaire. The parameters analysed were symptomatic relief, mobility and ease of management following insertion. One hundred and sixteen patients underwent PleurX catheter insertion by a single operator, 48 questionnaires were completed. Of the 48 cases analysed, improvement in all three quality of life indices was recorded following catheter insertion. Ease of mobility was recorded as moderately satisfied and very satisfied in 50% and 15% of patients, respectively. Symptomatic improvement was found to have been increased with 42% and 6% of patients responding to moderately satisfied and very satisfied, respectively. Ease of management was recorded as 'slightly satisfied' and moderately satisfied in 50% and 33% of patients, respectively, demonstrating a high satisfaction index in patients with chronic progressively debilitating malignancies. Complications were either transient or readily correctable. Pain was the predominant complication occurring in 35% of patients lasting <3 days. No patient required catheter removal for resolution of discomfort. Our findings support the use of PleurX catheters for palliative patients with malignant pleural effusions in the presence of trapped lung. The catheters are not only easy to insert and discrete but they can be managed effectively by patients and community nurse practitioners and prevent repeated admissions to hospital in palliative patients with compromised life expectancy.

Thymic cyst presenting as tachy-brady syndrome.

Tachy-brady syndrome or sick-sinus syndrome as it is also known is a cardiac rhythm disturbance resulting in alternating episodes of bradycardia and tachycardia. Diagnosis can be difficult because of its nonspecific symptoms and elusive findings on electrocardiogram or 24h tape. Thymic cysts are relatively uncommon tumours that are predominantly asymptomatic and located in the anterior mediastinum. We present the first known report of tachy-brady syndrome associated with a large thymic cyst. Treatment consisted of dual-chamber pacemaker implantation prior to video-assisted removal of the thymic cyst.

Massive bronchogenic cyst mimicking ischaemic chest pain.

The presentation of the bronchogenic cyst is variable making preoperative diagnosis difficult. The majority are either asymptomatic or discovered incidentally. The most common presenting symptoms are cough, fever and dyspnoea. We discuss the case of a large bronchogenic cyst in the posterior mediastinum mimicking ischaemic cardiac pain in a patient with known heart disease. This case demonstrates the need for detailed investigations prior to the treatment of an assumed acute coronary syndrome as a bronchogenic cyst may be the rare cause of such symptoms.

Compensatory hyperhidrosis: a consequence of truncal sympathectomy treated by video assisted application of botulinum toxin and reoperation.

Hyperhidrosis is a debilitating condition characterised by sweating that exceeds the need of normal thermoregulation. Surgical management of primary hyperhidrosis by upper dorsal sympathectomy is the treatment of choice for intractable hyperhidrosis, however, paradoxically it may be followed by troublesome compensatory hyperhidrosis in a significant number of patients. The frequency of compensatory hyperhidrosis often reflects the extensiveness of the denervation. We report for the first time the successful treatment of a patient who developed compensatory hyperhidrosis following sympathectomy using video assisted extension of the sympathectomy by application of botulinum toxin (BTX-A). In addition, this case highlights the use of botulinum toxin as a guide for the potential successful management of compensatory hyperhidrosis prior to definitive extension of a sympathectomy.
