VATS management of both PSP and SSP offers good short-term results and excellent long-term freedom from repeat surgery. In combination with bullectomy, results of abrasion and poudrage do not significantly differ from pleurectomy. We recommend abrasion for pleurodesis in young patients reserving poudrage for the elderly. Pleurectomy may not be necessary.
BackgroundPost-cardiotomy cardiogenic shock (PCCS) has an incidence of 2–6 % after routine adult cardiac surgery. 0.5–1.5 % are refractory to inotropic and intra-aortic balloon pump (IABP) support. Advanced mechanical circulatory support (AMCS) can be used to salvage carefully selected number of such patients. High costs and major complication rates have lead to centralization and limited funding for such devices in the UK. We have looked the outcomes of such devices in a non-transplant, intermediate-size adult cardiothoracic surgery unit.MethodsInclusion criteria included any adult patient who had received salvage veno-arterial extra-corporeal membrane oxygenation (V-A ECMO) or a ventricular assist device (VAD) for PCCS refractory to IABP and inotropic support following cardiac surgery from April 1995-April 2015.ResultsSixteen patients met the inclusion criteria. Age range was 34–83 years (median 71). There was a male predominance of 12 (75 %). Overall, 15 (94 %) had received ECMO of which, 10 (67 %) had received central ECMO and 5 (33 %) had received peripheral ECMO. One patient (6 %) had a VAD. The most common complication was haemorrhage. Stroke, femoral artery pseudo-aneurysm, sepsis and renal failure also occurred. Thirty-day survival was 37.5 %. Survival rate to hospital discharge was 31.2 %. All survivors had NYHA class I-II at 24 months follow-up.ConclusionsOur survival rate is similar to that reported in several previous studies. However, the use of AMCS for refractory PCCS is associated with serious complications. The survivors in our cohort appear to maintain an acceptable quality of life.
OBJECTIVES:We studied the influence of the number of sternotomy mechanical fixation points on deep sternal wound infection (DSWI). METHODS:Between September 2007 and February 2011, 2672 patients underwent a standard peri-sternal wire closure following a median sternotomy for a first-time cardiac surgery. Data were collected during the study period. RESULTS:The mean age of the patients was 66 ± 11 and 1978 (74.0%) were male. The mean body mass index (BMI) was 28.9 ± 9.3 and the median of the logistic EuroSCORE was 3.14, with a range of 0.88-54.1. Postoperatively, 40 (1.5%) patients developed DSWI after 14 ± 6 days, of whom 39 (92.5%) had positive deep sternal wound specimen cultures, predominantly Staphylococci (62.5%). The risk of DSWI was significantly increased in patients in whom eight or fewer paired points of sternal wire fixation were used when compared with patients in whom nine or more paired points of fixation were used (P = 0.002). Preoperative myocardial infarction (P = 0.001), elevated BMI (P = 0.046), bilateral internal mammary artery harvest (P < 0.0001), postoperative hypoxia (P < 0.0001), sepsis (P = 0.019) and postoperative inotrope use (P = 0.007) significantly increased the risk of DSWI.CONCLUSIONS: DSWI is associated with hypoxia, ischaemia, sepsis and mechanical sternal instability. DSWI may be prevented by using nine or more paired fixation points when closing with standard peri-sternal wires.
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether it is safe to cut the temporary epicardial pacing wires (TEPWs) flush with the patient's skin surface prior to discharge. Altogether 105 relevant papers were identified of which 13 case reports represented the best evidence to answer the question. The author, journal, date, country of publication, complications, the culprit TEPW and relevant outcomes are tabulated. All case reports demonstrated a wide spectrum of complications. Complications from a retained TEPW mainly arise after a long dormant period. A recent case report has demonstrated the herniation of intra-abdominal contents through a diaphragmatic defect created by the abandoned epicardial pacing wires after a few decades. In multiple case reports, the migration of TEPW was the culprit of serious complications. In two case reports, the TEPWs attached to the right chambers of the heart had migrated to the pulmonary artery via the right atrium and then the right ventricle. In one case report, a similar migration of the right ventricular TEPW to the right ventricular outflow track was observed. The TEPW migration was not limited to the right side of the heart, as in one case report the right atrial TEPW had migrated to the right carotid artery via the ascending aorta. A distant extravascular migration of TEPWs to the skin surface and intraperitoneal and pelvic cavities has also been reported. Retained TEPWs have also been reported to inflict complications locally. One case report has shown a large right-sided para-cardiac mass caused by a right atrial TEPW. In two other case reports, the bronchocutaneous fistula, lobar consolidation and bronchiectasis were the manifestations of a retained TEPW. We conclude that the retention of TEPW after cardiac surgery is not necessarily safe and may cause severe complications. We recommend that TEPWs should be completely removed when possible. If TEPWs are retained, this should be appropriately documented and the surgeon should be mindful of this when the patient presents with complications postoperatively.
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether it is safe to divide the left innominate vein (LIV) in aortic arch surgery to improve access. Altogether, 228 relevant papers were found using the reported search, of which nine represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Following LIV division, the venous drainage takes place via multiple collateral systems such as the azygous/hemiazygous, the internal mammary veins, the lateral thoracic and superficial thoracoabdominal veins, vertebral venous plexus as well as the transverse sinus. The possible complications are mainly left upper limb swelling and neurological symptoms. In one case series of 14 patients, the LIV was divided and ligated to facilitate the exposure for aortic arch surgery. More than 2-year follow-up did not reveal upper limb oedema or neurological symptoms. In two cohorts of 52 patients, the LIV was ligated prior to the superior vena cava (SVC) resection for malignancy. During the mid-term follow-up, no neurological or upper limb symptoms were reported. Although in two studies with 72 and 70 patients undergoing SVC resection it was not specified how many of them had LIV ligation, no relevant complications were reported. In a report, LIV occlusion was observed in 4 patients undergoing left internal jagular vein catheterization for haemodialysis. The reported symptom was left arm swelling with no neurological problems. In a cohort of 18 patients undergoing SVC resection for malignancy and major vein reconstruction, 7 patients underwent ligation of the LIV with no neurological symptoms. It was also concluded that reconstruction of the LIV is not consistent with favourable patency. In a case series of 10 patients with central venous obstruction, collateral pathways to conduct efficient venous drainage were mapped. We conclude that division of the LIV is safe in selected patients and operations. Patients will initially have symptoms of central vein obstruction, but these will decrease with conservative management as collaterals form.
Tricuspid valve endocarditis (TVE) is a growing concern with increasing rates and mortality burden. The currently changing etiology, the antibiotic resistance and the raise in iatrogenic causes as with implantable cardiac devices [cardiac implantable electronic device (CIED)], represent a challenge for the management of these patients. The progressively widespread use of CIEDs is adding to the more commonly known intravenous (IV) drug abuse in the list of causes. Treatment strategies include medical therapy alone or surgery. From the surgical standpoint tricuspid valve repair, replacement or the staged procedure of valvectomy as bridge to replacement are available options. Treatment of endocarditis related to implantable device is another expanding field which requires a coordinated action with microbiologists in consideration of the microorganism antibiotic resistance. This review summarizes the currently available evidences on TVE including surgical indications, timing of interventions and technical considerations. The conflicting results of the available observational evidences and the non-unanimous consensus on many aspects of TVE impede to reach a definitive conclusion regarding the best management strategy and demands for randomized studies in this field.
