A pilot study was undertaken to determine the feasibility of establishing a heart surgery programme in northern Nigeria. During three medical missions by a visiting US team, in partnership with local physicians, 18 patients with heart diseases underwent surgery at two referral hospitals in the region. Sixteen (88.9%) patients underwent the planned operative procedure with an observed 30-day mortality of 12.5% (2/16) and 0% morbidity. Late complications were anticoagulant related in mechanical heart valve patients and included a first-trimester abortion one year postoperatively, and a death at two years from haemorrhage during pregnancy. This has prompted us to now consider bioprosthetics as the valve of choice in women of childbearing age in this patient population. This preliminary result has further stimulated the interest of all stakeholders on the urgency to establish open-heart surgery as part of the armamentarium to combat the ravages of heart diseases in northern Nigeria.
The presence of a permanent tracheal stoma in a laryngectomized adult is a predisposing factor for foreign-body aspiration, as are conditions that impair normal protective airway mechanisms. Such an aspiration can cause significant morbidity if it is not properly managed. The use of rigid bronchoscopy to remove an aspirated object can be difficult in these patients, and a high percentage of them require thoracotomy, especially for the removal of sharp objects. An emphasis on patient education regarding the handling of objects around the stoma in laryngectomized adults is key to preventing aspiration and its complications.
Infections, malignancy and trauma currently account for the bulk of cardiothoracic surgery practice in Nigeria, with surgical activity showing a predominance of minor procedures and comparatively minimal OHS activities. Identified challenges to increasing cardiothoracic surgical activity were limitations in manpower development, infrastructure, laboratory support, local availability of consumables, cost of surgery, funding mechanisms for surgery, multiple models for development of cardiac surgery, decentralization of efforts and lack of outcome data. Data collection and reporting of results must be started to enable development of more evidence-based practice.
Purpose: Active heart surgery programs are few in sub Saharan Africa outside of South Africa, with majority being low volume centers performing small numbers annually. We reviewed our long term outcome to identify factors associated with increased morbidity and mortality, to guide future choice of prosthetic valves in our mostly indigent patients afflicted with rheumatic valvular disease. Methods: Retrospective analysis of patients who underwent heart valve replacement at Lagos State University and Ahmadu Bello University Teaching Hospitals from November 2004 to February 2009. Results: Twenty six patients, 19 (73.1%) females, age 12-47; mean 26.69 ± 9.87 years, underwent heart valve replacement. 19 (73.1%) patients had mitral and 7 (26.9%) aortic valve replacement. Mechanical valve was implanted in all except in 2 (7.7%) patients. Left ventricular ejection fraction was >50% in 14 (53.8%), 24 (92.3%) were in New York Heart Association class III/IV, 10 (38.5%) had severe pulmonary hypertension and logistic euroscore was 5.84 ± 3.81. Operative mortality was 11.5% (3/26) and morbidity 7.7% (2/26). Follow-up for survivors was 83.0 ± 27.9 months. 10-year freedom from bleeding and thromboembolism was 70.0% and survival 86.0%. Linearized rate for bleeding was 4.58 and thromboembolism 1.52. Conclusion: Late complications in survivors were primarily anticoagulant related occurring predominantly in child bearing age females especially during pregnancy. Bleeding complications were often associated with noncompliance due to poor socioeconomic status. With average life expectancy of 53 years for females, bioprosthetic valves despite higher structural failure rate, may be best suited especially in child bearing age females still desirous of childbirth to decrease valve related complications. Longer duration of follow-up and meta-analysis of future reported series from the sub
Background: The majority of prospective cardiac surgical patients in sub Saharan Africa lack access to open heart surgery. We reviewed our midterm results to identify the obstacles to growth and challenges with sustainability. Methods: Records of patients undergoing heart surgery at LASUTH from December 2004 to March 2006 were retrospectively reviewed for clinical and outcome data. Results: Twenty four patients age 10 -50, mean 28.0 +/− 10.49 years and 13 (54.2%) males underwent surgery. 12 (50.0%) patients had mechanical valve replacements, 11 (45.8%) closure of septal defects and 1 (4.2%) left atrial myxoma resection. Logistic euroscore for valve patients was 5.81 +/− 4.74 while observed mortality was 8.3% (1/12). Overall 30 days operative mortality was 8.3% (2/24) and major morbidity 4.2% (1/24). Patients with septal defects closure stopped clinic visits within a year. Valve patients follow up was complete in 90.1% with mean duration of 55.2 +/− 15.3 months. Late events occurred only in females with mitral valve replacements. The 5-year freedom from thromboembolism and bleeding was 74.0% and survival 82.0% in valve patients. Conclusion: Despite limited resources heart surgery can safely be performed with good outcomes by trained local personnel under supervision of visiting foreign teams until they are proficient to operate independently. Patients with less complex congenital defects have excellent postsurgical outcomes, while patients with rheumatic valve replacement are subject to ongoing valve related morbidity and mortality therefore require lifetime follow up. Choice of prosthetic valve for the mostly indigent and poorly educated population remains a challenge. We now prefer stented tissue valve despite its known limitations, in child bearing age females desirous of childbirth and others unlikely to comply with anticoagulation regimen. Barriers to sustainability include poor infrastructures, few skilled manpower, inadequate funding and restricted patient access due to inability to pay without third party insurance or government Medicaid.
