Challenges in the management of cerebrospinal fluid ascites: a case report.

Cerebrospinal fluid (CSF) ascites is an uncommon sequela of ventriculo-peritoneal (V-P) shunt. We report a case of CSF ascites in a 7-year-old girl with craniopharyngioma and the challenges and limitations we faced in her management. Ascites completely resolved after a ventriculo-atrial (V-A) shunt surgery. Abdominal paracentesis, diuretics, and ventriculo-pleural shunt were not effective in the management of the CSF ascites.

Utilisation of blood and blood products during open heart surgery in a low-income country: our local experience in 3 years.

BACKGROUND: In Nigeria, access to open heart surgery (OHS) is adversely affected by insufficient blood and blood products, including the challenges because of the lack of patient-focused blood management strategies owing to the absent requisite point-of-care tests in the operating theatre (OR)/ICU. In addition, the limited availability of altruistic blood donors including the detection of transfusion transmitted infections more commonly among non-altruistic blood donors is another burden affecting the management of excessive bleeding during and after open heart surgery in our country. OBJECTIVE: The objective of this study was to review our local experience in the use of blood and blood products during open heart surgery and compare the same with the literature.Materials and methodsIn a period of 3 years (March, 2013-February, 2016), we performed a retrospective review of those who had open heart surgery in our institution. The data were obtained from our hospital health information technology department. The data comprised demography, types of operative procedures and units of blood and blood products transfused per procedure, including the details regarding the usage of the cell saver, as well as those who had severe bleeding requiring excessive blood transfusion. RESULTS: During the study period, 102 patients had open heart surgery, an average of 34 cases in a year. Among them, there were 75 (73.53%) males and 37 (36.27%) females, giving a ratio of 2:1. The ages of the patients were from 0.6 (7/12) to 74 years. Mitral valve procedure was the most common (n=22, 21.6%) surgery type. Transfusion requirements averaged 1.9 units of fresh frozen plasma, 0.36 units of platelet concentrate, and 1.68 units of packed cells per procedure. The least common surgical procedure was common atrium repair (n=1, 0.01%). CONCLUSION: Open heart procedure is a very complex procedure requiring cardiopulmonary bypass with associated severe perioperative bleeding. The attendant blood loss and haemostatic challenges are combated by intricate and selective transfusions of allogeneic blood and or blood products.

Management of complex CHD at the National Cardiothoracic Center of Excellence, University of Nigeria Teaching Hospital, Enugu: the role of foreign cardiac missions in 3.5 years.

BACKGROUND: CHD is defined as structural defect(s) in the heart and proximal blood vessels present at birth. The National Cardiothoracic Center of Excellence, University of Nigeria Teaching Hospital (UNTH), Enugu, through the aid of visiting Cardiac Missions has managed a significant number of patients within the last 3.5 years. Aim/Objective The objective of this study was to review surgical options and outcome of complex CHD among patients attending UNTH, Enugu, Enugu. Materials and Method During the period of 3.5 years (March, 2013 to June, 2016), a total of 20 cases of complex CHD were managed by cardiac missions that visited UNTH, Enugu. Their case notes and operating register were retrieved, reviewed, and analysed using SPSS version 19 (Chicago). RESULTS: There were eight females and 12 males, with a ratio of 2:5. The age range was from 5 months to 34 years with a mean of 1.7. Among all, five patients died giving a mortality rate of 25%. The operative procedures ranged from palliative shunts to complete repair. The outcome was relatively good. CONCLUSION: Complex CHD are present in our environment. Their surgical management in our centre is being made possible by periodic visits of foreign cardiac missions.

Colon interposition graft for corrosive esophageal stricture: midterm functional outcome.

BACKGROUND: Corrosive esophageal stricture is a major cause of morbidity among Nigerians. In most cases, this follows accidental or parasuicidal ingestion of caustic sodium hydroxide solution (NaOH) often used in the local production of soaps. Various treatment modalities have been advocated for the treatment of esophageal stricture. In this study, we review the results of our adopted technique in the past 10 years for pedicled colonic interposition. METHODS: This is a retrospective study of 21 patients who underwent substernal isoperistaltic pedicled colonic interposition graft for management of corrosive esophageal stricture. The right colon was pulled up into the neck in all the patients without resecting the strictured esophagus. RESULTS: Long segment strictures and multiple strictures were the main indications for the procedure. The mean duration of the procedure was 339.6 ± 71.1 min. The average intraoperative blood loss was 673.1 ± 398.1 mL. There were two (9.5 %) hospital mortalities. Graft infarction (9.5 %), cervical fistulae (19.0 %), and reflux neo-esophagitis (14.3 %) were the main non-fatal complications. In the mid-term, dysphagia was completely relieved in a little over 84 % (16/19) of patients, while one patient (4.8 %) still experienced reflux neo-esophagitis requiring treatment. There was no case of gross regurgitation or nocturnal aspiration in the mid-term. CONCLUSIONS: Although the use of pedicled colonic interposition graft offers a good mid-term functional outcome with relief of dysphagia, early postoperative morbidity is high. Graft infarction is the single most important factor for poor functional outcome and every effort must be made to prevent its occurrence.

Incomplete vascular ring of the aortic arch presenting with dysphagia in an adult: case report.

Anomalies of the arterial branches of the arch of the aorta are rare, with the aberrant right subclavian artery being the most common of this anomaly. Majority of the anomalies are asymptomatic and often discovered as incidental findings. In the great majority of the symptomatic cases, the presentation may be either with breathlessness or dysphagia or both. This is in addition to the nature of the intrinsic arterial disease of the aberrant vessel, especially in adult patients; and unless borne in mind, the diagnosis is often missed leading to delays and wrong treatment. In this report we present a case of dysphagia in an adult male Nigerian initially diagnosed as œsophageal stricture from herbal potion ingestion but review of his imaging investigations gave a final diagnosis of dysphagia lusoria from an aberrant right subclavian artery. The difficulty in making a diagnosis and the need for a multidisciplinary review of the imaging investigations are highlighted. The patient was successfully treated by a combined trans-thoracic and cervical approach with division and re-implantation of the aberrant vessel unto the right common carotid artery. He has remained symptom-free for 2 years after surgery. Although the great majority of these anomalies are often asymptomatic, it is important they are borne in mind both in imaging investigations as well as in procedures involving structures in the upper visceral mediastinum. Various surgical approaches have been documented in the management of symptomatic ones; it is however recommended that options that ensure revascularization of the affected limb be selected.

Challenges of lung cancer management in a developing country.

BACKGROUND: The investigation of pulmonary neoplasm in Nigeria is hampered by lack of investigative tools and religio-cultural beliefs that detest autopsy. However, recent publications seem to suggest an increasing incidence of this lesion in Nigeria. MATERIALS AND METHODS: A 30-month prospective study of all cases of lung cancer seen at a tertiary health institution in Nigeria was done to document the incidence and challenges of management in the region. RESULTS: Fifty one new cases of primary carcinoma of the lung were identified during the study period. The age ranged from 30-81 years, mean 56.6 +/- 21.6 years and male:female ratio of 2.4:1. The age-standardized incidence rate was 7.9 per 100.000 with a peak in the 60-69 year age group. In 42% of the males there was cigarette smoking history. Adenocarcinoma of the lung was the predominant histologic subtype, and treatment was largely palliative. CONCLUSION: The incidence of lung cancer in South East Nigeria is on the increase even in the absence of state-of-the-art diagnostic modalities. The high prevalence of cigarette smoking amongst the males is a call for the intensification of the preventive measures against tobacco use.

Bilateral Giant Familial Carotid Body Tumors With Concomitant Skull-Base Paraganglioma and Facial Nerve Palsy.

Carotid body tumors, rare neck paragangliomas arising from the common carotid artery bifurcation, can be classified as sporadic, hyperplastic, or familial. The familial type is often bilateral and associated with germline mutation of the mitochondrial enzyme succinate dehydrogenase. We report the rare case of a 42-year-old man who presented with bilateral giant familial carotid body tumors associated with a concomitant skull-base paraganglioma, left-sided facial nerve palsy, and an incomplete circle of Willis. We describe the excision of the tumors in 2 stages (the left mass and associated paraganglioma first and the right mass second), 6 months apart, with use of general anesthesia, and we discuss other operative considerations.

Outcomes of Surgical Management for Patent Ductus Arteriosus in Infants in Nigeria.

BACKGROUND: Patent ductus arteriosus is a common cardiac anomaly in infants that, if untreated, is associated with high morbidity and mortality rates. In lower-middle-income countries, such as Nigeria, obtaining cardiovascular surgical care for infants remains difficult. In recent years, especially with the assistance of international voluntary cardiac organizations, efforts have increased to provide cardiac surgical services to this underserved population. METHODS: In this case series, the authors describe outcomes in 30 infants surgically treated for patent ductus arteriosus between 2013 and 2019 at an emerging cardiac center in Nigeria (9 male [30%] and 21 female [70%]; mean [SD] age, 8.2 [3.01] months; mean [SD] weight, 5.3 [1.52] kg; mean [range] weight deficit, 34.5% [15%-60%]). RESULTS: All the infants presented with patent ductus arteriosus as the main cardiac lesion, and 4 (13%) were syndromic. The mean (SD) patent ductus arteriosus diameter was 4.73 (1.46) mm. Surgical closure was completed in 29 infants; 1 died before surgery. No procedure-related deaths occurred, but 2 cases of trivial residual patent ductus arteriosus were recorded. CONCLUSION: Overall, surgical outcomes were excellent, with acceptable mortality rates. Perioperative care will continue to improve as the center is built to a self-sustaining capacity. Findings of this research at this emerging cardiac center in a developing country are a testament to the positive contribution made by international voluntary cardiac missions.

Improving the diagnostic recognition of thoracic endometriosis: Spotlight on a new histo-morphological indicator.

The diagnosis of thoracic endometriosis (TE) is challenging, hence resulting in under-diagnosis as well as long delays before arriving at a correct definitive diagnosis. Our aim is to review the histopathological findings in TE, summarise the diagnostic features, identify any major histo-morphological indicator(s) hitherto unrecognised as such, suggest diagnostic criteria; all with the aim of improving the diagnostic capacity and reducing observer error even where the clinical suspicion is low. A case-control study in which a search in the pathology archives of a referral hospital over a 10-year period was conducted. Twenty-six cases of TE were identified, reviewed, and compared with a control population of 48 cases taken from common benign thoracic diseases. Nine notable histological features were identified in varying permutations in the test group, namely: endometrioid glands, lymphoid clusters, ceroid macrophages, siderophages, cholesterol crystals, capillary congestion, multinucleated giant cells, smooth muscle bundles and fibrosis. The first 6 features were frequent; each being present in over 13 (13/26; 50%) test cases. The first 8 features showed significant association with TE by the Chi-squared test (P<0.05). In this group, the strength of association is high for the first 4 features (Cramér's V≥0.5). The presence of ceroid macrophages is shown to be a novel key feature, previously unrecognised as such, for the identification of TE. The presence of any three of four features including endometrioid glands, lymphoid clusters, ceroid macrophages and siderophages is a suggested criterion for the definitive diagnosis of TE.

Thoracic endometriosis syndrome in Nigeria: a single-centre experience.

OBJECTIVES: Thoracic endometriosis syndrome (TES) is the presence of functional endometrial tissue in or around the lung. There seem to be differences in the clinical presentation of this condition among Nigerian patients. We aim to study the clinical presentation and management outcome of TES in our centre. METHODS: This is an analysis of consecutive patients with TES treated over a 5-year period and followed up for 6 months to 5 years. Information collected included the gynaecological history, clinical presentation, causes of misdiagnosis, modalities of treatment and outcome. RESULTS: Twenty-three patients with TES aged between 24 and 45 years (median 32 years) were treated. Severe dysmenorrhoea was a prominent symptom in 91.3% of cases (median dysmenorrhoea score 8) and was uninfluenced by the marital status (P = 0.522). The patients usually presented with massive or recurrent haemothorax associated with massive ascites [16/23 (69.5%) of cases (P = 0.0006)]. The right side alone was involved in 21 cases and 1 patient had catamenial haemoptysis as a part of her symptoms, even though there was bronchial bleed at bronchoscopy in 6 patients. In 40%, tuberculosis was the misdiagnosis. Diagnosis was established histologically in 18/23 (78.3%) of the cases. Treatment was multimodal and multidisciplinary with notable macroscopic lesions in 77.8% of the patients that had surgery. CONCLUSIONS: TES is not an uncommon lesion. Presentation with massive haemothorax is usually associated with massive ascites. A large percentage of such have pleural and diaphragmatic lesions that require surgical treatment. The ascites may be refractory to treatment requiring repeated paracentesis.

Traumatic common carotid-jugular fistula: report of 2 cases.

Traumatic common carotid artery-to-internal jugular vein fistula is a rare entity that is not usually detected during the acute injury phase. We present 2 cases of traumatic carotid-jugular fistula. Both involved the right side of the neck, and both were due to injury from a firearm. The patients exhibited signs of high cardiac output. In Patient 1, the diagnosis was made by clinical examination and radiography. After diagnosis, the patient's parents requested his discharge from the hospital because of an inability to pay for treatment. The patient did not return. Patient 2 had a brachial plexus injury in addition to a carotid-jugular fistula. Diagnosis of the fistula was confirmed by color-flow echo Doppler scanning. Treatment consisted of division of the fistula and direct suture repair. The surgery required cross-clamping of the common carotid artery for 25 minutes; nonetheless, the patient recovered without cerebral ischemia. Carotid-jugular fistula should always be treated early to avoid the complications associated with the injury.

Tube thoracostomy: complications and its management.

Background. Tube thoracostomy is widely used throughout the medical, surgical, and critical care specialities. It is generally used to drain pleural collections either as elective or emergency. Complications resulting from tube thoracostomy can occasionally be life threatening. Aim. To present an update on the complications and management of complications of tube thoracostomy. Methods. A review of the publications obtained from Medline search, medical libraries, and Google on tube thoracostomy and its complications was done. Results. Tube thoracostomy is a common surgical procedure which can be performed by either the blunt dissection technique or the trocar technique. Complication rates are increased by the trocar technique. These complications have been broadly classified as either technical or infective. Technical causes include tube malposition, blocked drain, chest drain dislodgement, reexpansion pulmonary edema, subcutaneous emphysema, nerve injuries, cardiac and vascular injuries, oesophageal injuries, residual/postextubation pneumothorax, fistulae, tumor recurrence at insertion site, herniation through the site of thoracostomy, chylothorax, and cardiac dysrhythmias. Infective complications include empyema and surgical site infection. Conclusion. Tube thoracostomy, though commonly performed is not without risk. Blunt dissection technique has lower risk of complications and is hence recommended.
