Cardiac electrical storm is associated with deleterious clinical and psychological sequelae. Management can be challenging in a resource-poor environment. Old anti-arrhythmic medications can still be effective when conventional ones fail.

Assessing the different access types would help minimize peri-dialytic events and improve outcome. Methods: This was a retrospective, age and sex-matched, comparative study that assessed dialysis sessions with tunneled dialysis catheters (TDCs) with arteriovenous fistula (AVF). Results: Two hundred and four participants with 1062 sessions were involved. The male participants had 66.7% of all sessions, 60.6% of sessions with TDCs and 87.3% of sessions with AVF, P=0.001. The elderly constituted 23.5% of all participants but 37.7% of sessions with AVF, P=0.04. The percentage of the health-insured was more in sessions with AVF compared to the study population, P<0.001. Diabetics were more likely to use the TDCs, P=0.06. Participants using AVF were more likely to receive full dialysis and erythropoietin treatment, P<0.001. Intradialytic hypotension and dialysis termination were commoner with AVF than TDCs, P=0.03 and P=0.04 respectively. The dialysis dose was higher with AVF than TDCs, P=0.02. Predictors of AVF as dialysis access were male gender, advancing age, health insurance and full treatment compliance. Conclusion: There is predominance of venous catheters in our dialysis population. The AVF gave better BP control, fluid and solute clearance, and dialysis dose, and was commoner with males, the health insured and older participants. Intradialytic hypotension was commoner with AVF as IDHT was commoner with TDCs.

Diseases affecting the major organ systems of the body and higher grades of surgery are common risk factors for MA. It is associated with poor treatment outcome. Aim: To determine the risk factors and clinical correlates of metabolic acidosis and assess its relationship with treatment outcome. Methodology: A retrospective study at the "Tristate Heart and vascular Center" in Ilishan-Remo South west Nigeria, on patients that had cardiac and vascular surgeries from January 2015 to December 2019. Three hundred and forty two participants took part in the study. The demographic, clinical and laboratory findings were entered. Statistical analysis was with Student's t-test and Chi square. Results: Two hundred and six males and 136 females were studied. The incidences of metabolic acidosis prior to induction, on post-operative day one (POD 1) and on POD 28 were 20.7%, 39.8% and 14.1% respectively. Nine (2.6%) participants died during admission, of this, 6 (66.7%) had MA at presentation but all (100%) had MA on POD 1. The Risk factors for MA were advanced age, comorbidities, open heart surgery, elevated systolic blood pressure and low eGFR. Metabolic acidosis was a risk factor for prolonged hospital stay, perioperative death and declining kidney function which was commoner among participants with preexisting kidney dysfunction. Conclusion: The incidence of metabolic acidosis was 20.7% at induction of anesthesia, rose to 39.8% on POD 1 and by POD 28 , it has significantly reduced to 14.1%.

Primary tracheobronchial malignancies make up about 0.1% of all pulmonary tumors. The survival rate depends on several factors which include the malignant potential of the tumor, the patient’s comorbidities, and the location of the tumor. The index case is a 60-year-old woman who had 7 months history of globus with an associated history of central chest discomfort and cough of 3 months duration. There was a positive history of dysphagia to solid meals, odynophagia, dyspepsia, nausea, excessive belching, bloating, and regurgitation. These symptoms led to the diagnosis of gastroesophageal reflux disease. However, the persistent symptom of globus and worsening cough necessitated her referral to the chest clinic. Chest radiograph revealed opacity in the left upper lobe. Chest computerized tomographic scan showed a solitary, lobulated, and calcified soft-tissue mass in the apicoposterior segment of the left upper lobe with loss of ...

This is an unusual case of posttraumatic PP associated with severe hemorrhage as a result of glass-cut injury. Our patient had bled repeatedly from the injury, necessitating transfusion with a total of seven pints of blood over a four week period prior to presentation. Duplex ultrasonography established the diagnosis of PP which was confirmed at surgery. This case highlights the significance of duplex ultrasonography in the pre-operative evaluation of patients with vascular trauma, especially in sub-Saharan Africa where computed tomography and digital subtraction angiography may not be readily available or affordable.

Its application in Nigeria has however been limited and not been reported. The aim of this study was to describe our institutional experience and challenges with VATS. Materials and Methods: This was a retrospective cross-sectional study of all patients that underwent VATS in our institution between March 2008 and June 2013. Data were extracted from a prospectively maintained database. Results: Two hundred and sixty-one patients were assessed as potential VATS cases. VATS was initiated in 26 patients, but completed in 25 patients (9.6%) as there was one case of conversion of a planned VATS bullectomy due to the failure of one lung ventilation. There were 12 males and 13 females. Mean age was 40.7 ± 13.9 years. The indication was interstitial lung disease in 9 patients (36%), malignant pleural effusion in 6 patients (24%), spontaneous pneumothorax in 5 patients (20%), indeterminate pulmonary nodule in 2 patients (8%), pleural endometriosis in 2 patients (8%) and bronchogenic cyst in one patient (4%). Procedures performed were lung biopsy in 13 patients (52%), pleural biopsy and pleurodesis in 6 patients (24%), bullectomy and pleurodesis in 5 patients (20%) and excision of bronchogenic cyst in one patient (4%). Mean hospital stay was 4 ± 0.7 days. There were no complications and no mortalities. Conclusion: VATS is being performed in our institution with successful outcomes. The use of VATS in Nigeria is encouraged. The relatively high cost of VATS is, however, a major limitation to more widespread use.

We studied intraoperative hypotension (IOH) and its immediate and short term relationship with post-operative mortality. Materials & Methods: A retrospective study of participants, 16-86 years old who underwent cardiac and vascular surgery at Tristate Heart and Vascular Center, Ilishan-Remo, Nigeria, a high dependency cardiac and vascular surgical center between January 2015 and March 2021. Study participants were grouped into three cohorts and primary outcome was all-cause post-operative death. Results: The records of four hundred and fifteen (258 males and 157 females) cohorts were studied, with mean age of 56.6 ± 5.4 years, 14.69% of the participants were 65 years or older. The surgeries were coronary artery bypass graft (CABG) alone (26.03%), CABG with valve surgery (38.31%) and, valves surgery alone (35.66%). The mean arterial pressure (MAP) pre-induction, and intra-operative and immediate post-op were 71.37 ± 14 09 mmHg, 68.6 ± 11.24 mmHg and 72.24 ± 33 mmHg respectively. The incidence of IOH was 86.30%, prevalence of background kidney dysfunction was 29.40% and incidence of AKI was 25.54%. Eleven (2.65%) participants died, all (100%) had IOH, 1 (9.09%) was intradialytic.

There is however no national registry or framework for pacemaker data collection. A pacemaker database has been developed in our institution and the results are analyzed in this study. Methods: The study period was between January 2008 and December 2012. Patient data was extracted from a prospectively maintained database which was designed to include the fields of the European pacemaker patient identification code. Results: Of the 51 pacemaker implants done, there were 29 males (56.9%) and 22 females (43.1%). Mean age was 68.2±12.7 years. Clinical indications were syncopal attacks in 25 patients (49%), dizzy spells in 15 patients

This vascular ring compressed the trachea, requiring operative intervention. A median sternotomy gave access for an aorta-to-left brachiocephalic artery bypass and division of the vascular ring. This is a unique case, because vascular rings rarely present in elderly patients with such acute life-threatening symptoms. To our knowledge, this is the oldest and heaviest patient ever reported with symptomatic presentation and one of only 4 patients over the age of 50. The current literature on vascular rings of the thoracic aorta in adults is reviewed.

At this early phase of development it is faced with multiple challenges, especially financing and local skilled manpower for which solutions have to be identified in order to ensure sustainability and future growth. This study is aimed at highlighting these obstacles to growth of cardiothoracic surgery based on our own institutional experience at Lagos State University Teaching Hospital (LASUTH) and the current status of OHS activity in other cardiothoracic centers in Nigeria. Prospectively acquired data from our center from March 2004 to December 2015 was reviewed. A telephone survey was also conducted with all other institutions in Nigeria performing cardiac surgery. During the study period 1,520 patients underwent various procedures with a mean ag...

The aim of this study was to determine the clinical and angiographic profile of Nigerians with CAD. Methods: This was a prospective cross-sectional study conducted between July 2009 and July 2012. The target patient population was Nigerian patients in whom CAD was confirmed by coronary angiography. Criteria for confirmation was the presence of any major epicardial vessel or branch with >50% stenosis. The data was extracted from a prospectively maintained database. Results: 2,808 medical patients were seen during the study period. 152 patients were evaluated for Ischaemic Heart Disease (IHD), and coronary angiograms were normal or showed minimal disease in 72 patients (47.4%). CAD was confirmed in 80 patients (52.6%), so the prevalence of CAD was 2.8%. The sex distribution was 53 males (66.2%) and ...

While the direct effects of the pandemic in regard to morbidity and mortality appear to be more significant in the developed world, the indirect harmful effects on already insufficient healthcare infrastructure on the African continent would in the long term be more detrimental to the populace. Women and children form a significant vulnerable population in underserved areas such as the sub-Saharan region, and expectedly will experience the disadvantages of limited healthcare coverage which is a major fall out of the pandemic. Paediatric cardiac services that are already sparse in various sub-Saharan countries are not left out of this downsizing. Restrictions on international travel for patients out of the continent to seek medical care and for international experts into the continent for regular mission programmes leave few options for children with cardiac defects to get the much-needed...
