Percutaneous construction of ventriculo-atrial (VA) shunt - Case report.

INTRODUCTION AND IMPORTANCE: The commonest method of elective CSF diversion remains ventriculo-peritoneal shunt (VP shunt). But in some circumstances, VP shunts fail repeatedly or becomes unattractive to the neurosurgeon and this calls for exploration of alternatives. For the index case, Ventriculo-atrial (VA) shunt was favoured and the objective in this report is to share experience gathered there from. Learning points serve to highlight the use of VA shunts as a resort in the drainage of cerebrospinal fluid in the case of repeated failures of peritoneal diversion of CSF and to explain our explain our experience with this index case. CASE PRESENTATION: A 54 years old obese woman with previous history of total abdominal hysterectomy was reported. She underwent repeated (three times) revisions of failed peritoneal end of her VP shunt on a background of obstructive hydrocephalus secondary to a posterior fossa tumour (previously excised). Following repeated failure of peritoneal catheter function, she underwent VA shunt and did well. CLINICAL DISCUSSION: The decision to place a VA shunt was made after careful deliberations. We discuss the peculiarities in placing a VA shunt. Following placement of a VA shunt, improvement was noted in her clinical condition at one week post op and has been sustained at multiple follow up clinic visits. CONCLUSION: VA shunts become an option for cerebrospinal fluid drainage when it becomes unequivocally clear in a multidisciplinary setting that the peritoneal catheter is unlikely to work in view of the unfavourable circumstances of the peritoneal cavity.

Boerhaave's syndrome after pentazocine-induced vomiting in a 21-year-old male with asthma: a case report.

Boerhaave's syndrome is an uncommon syndrome characterized by spontaneous rupture of the oesophagus with a high mortality rate. While excessive alcohol intake and binge-eating are the classic precipitants of this syndrome, medication-induced vomiting causing Booerhave's is quite uncommon. Traditionally managed operatively, conservative management is being increasingly reported in selected cases. We report the case of 21-year-old male with who developed sudden onset chest pain and dyspnoea after pentazocine induced vomiting. He was referred after lack of response to initial treatment for acute severe asthma. A chest CT scan showed pneumomediastinum, subcutaneous emphysema and oesophageal tear. He was managed conservatively with oxygen therapy, nil per mouth and antibiotics with improvement of symptoms and discharge after 8 days.

Treatment Outcomes of Tuberculous and Non-tuberculous Empyema Thoracis.

Background: Pulmonary tuberculosis remains prevalent in the developing parts of the world. Besides the consequent tuberculous pleurisy, which can be complicated by empyema thoracis, Mycobacterium tuberculosis is associated with significant lung parenchymal disease that poses an additional clinical challenge in achieving a successful outcome of management. This study compared the outcomes of management of tuberculous versus non-tuberculous empyema thoracis managed at the Ahmadu Bello University Teaching Hospital (ABUTH), Zaria, Nigeria. Materials and Methods: A prospective study of patients being managed for empyema thoracis at the ABUTH, Zaria, within a 22-month study period was conducted. Recruitment into the study included all consecutive patients managed for empyema thoracis in ABUTH, Zaria, after obtaining consent. The required data were collected using a structured proforma. These included data on aetiology, microbial isolates, and initial and total empyema volumes. Sociodemographic data (including age, gender, educational level, and occupation) were also noted. The patients were subsequently managed, and the outcomes of management were noted. These outcomes included the duration of drainage, the duration of hospital stay, complications, lung expansion following drainage, and the need for decortication. Data obtained from the study were analysed using the Statistical Package for the Social Sciences (SPSS) version 20 software (IBM Corp. IBM SPSS Statistics for Windows. Version 20.0. Armonk, NY: IBM Corp.; released 2011) and the statistical differences determined using the chi-square test and the student's t-test. Results: Eighty-three patients were enrolled in the study, 20 (24.1%) of whom were females. Fourteen (16.9%) patients had tuberculous empyema thoracis, whereas 69 (83.1%) had non-tuberculous empyema thoracis. Patients with tuberculous empyema were significantly older than those with non-tuberculous disease (mean age 37.9 years [standard deviation {SD} = 20.6 years] vs. 26.8 years [SD = 18.2 years], P = 0.045). Compared to non-tuberculous empyema, tuberculous empyema thoracis was associated with lower percentage of mean lung expansion (60.9% [SD = 22.7%] vs. 78.4% [SD = 16.8%], P = 0.001), more than six-fold increased need for decortication (odds ratio = 6.58 [95% confidence interval = 1.84-23.52], P = 0.004), and longer period of hospital stay (36.4 days [SD = 3.8 days] vs. 23.6 days [SD = 16.2 days], P = 0.004). Conclusion: Tuberculous empyema thoracis was associated with worse outcomes (in terms of percentage of lung expansion, need for decortication, and length of hospital stay) compared to non-tuberculous empyema thoracis.

Contexte: La tuberculose pulmonaire reste répandue dans les régions en développement du monde. Outre la pleurésie tuberculeuse qui en résulte qui peut être compliquée par un empyème thoracique, Mycobacterium tuberculosis est associé à une importante maladie du parenchyme pulmonaire qui constitue un défi clinique supplémentaire pour obtenir un résultat positif de la prise en charge. Cette étude a comparé les résultats de la prise en charge de l'empyème thoracique tuberculeux et non tuberculeux géré à l'hôpital universitaire Ahmadu Bello (ABUTH), Zaria, Nigéria. Méthodologie: Une étude prospective de patients pris en charge pour empyème thoracique à l'hôpital universitaire Ahmadu Bello (ABUTH), Zaria au cours d'une période d'étude de 22 mois a été menée. Le recrutement dans l'étude a inclus tous les patients consécutifs traités pour empyème thoracique à ABUTH, Zaria, après obtention du consentement. Les données requises ont été collectées à l'aide d'un formulaire structuré. Celles-ci comprenaient des données sur l'étiologie, les isolats microbiens et les volumes d'empyème initiaux et totaux. Les données sociodémographiques (notamment l'âge, le sexe, le niveau d'instruction et la profession) ont également été notées. Les patients ont ensuite été pris en charge et les résultats de la prise en charge ont été notés. Ces résultats comprenaient la durée du drainage, la durée du séjour à l'hôpital, les complications, l'expansion pulmonaire après le drainage et le besoin de décortication. Les données obtenues à partir de l'étude ont été analysées à l'aide du logiciel Statistical Package for Social Science (SPSS) version 20 (IBM Corp. Released 2011. IBM SPSS Statistics for Windows, Version 20.0. Armonk, NY: IBM Corp.) et les différences statistiques ont été déterminées à l'aide de Test du chi carré et test t de Student. Résultats: Quatre-vingt-trois patients ont été inclus dans l'étude, dont 20 (24.1%) étaient des femmes. Quatorze (16.9%) patients avaient un empyème thoracique tuberculeux tandis que 69 (83.1%) avaient un empyème thoracique non tuberculeux. Les patients atteints d'empyème tuberculeux étaient significativement plus âgés que ceux atteints d'une maladie non tuberculeuse (âge moyen 37.9 [SD20.6] ans 26.8 [SD18.2] ans, P = 0.045). Par rapport à l'empyème non tuberculeux, l'empyème thoracique tuberculeux était associé à un pourcentage d'expansion pulmonaire moyen plus faible (60.9 [SD22,7] % contre 78.4 [SD16.8] %, P = 0.001), un besoin de décortication plus de six fois supérieur (rapport de cotes 6.58 [IC à 95% 1.84­23.52], P = 0.004), et durée d'hospitalisation plus longue (36.4[SD3.8] jours contre 23.6[SD16.2] jours, P = 0.004). Conclusion: L'empyème thoracique tuberculeux était associé à de moins bons résultats (en termes de pourcentage d'expansion pulmonaire, de besoin de décortication et de durée d'hospitalisation) par rapport à l'empyème thoracique non tuberculeux.

Initial Experience with Central Venous Line Insertion in a Tertiary Health Institution in Nigeria.

BACKGROUND: Central venous catheterization is an uncommon procedure in most hospitals in the West African subregion. This article presents our initial experience with central line insertion. MATERIALS AND METHODS: Catheter sizes ranged from 5 fr for children and 7 fr for adult for intravenous therapy, while size 7 fr polyurethane catheters were used for children requiring hemodialysis and sizes 12-14 fr silicone catheters for adolescents and adults requiring hemodialysis'. Data were collected prospectively using a structured pro forma over a 2-year period (June 2010-May 2012) and analyzed with SPSS 15. RESULTS: A total of 77 lines were inserted four as tunneled lines and 73 as nontunneled lines. Forty-seven (61.0%) patients were male, 30 (39.0%) were female, with age range of 1-80 years. The success rate was 97.4%. The overall complication rate was 16.9%. CONCLUSION: Our initial experience with the use of central venous lines, was marked by a high success rate, few manageable complications and no mortality over the study period. Majority of insertions were done by the bedside under local anesthesia lending credence to the assertion that it is a relatively safe procedure that can be done by any adequately trained doctor and should, therefore, be encouraged in our hospitals.

Sensitivity of Computed Tomography-guided Transthoracic Biopsies in a Nigerian Tertiary Institution.

INTRODUCTION: The indications for open biopsies for intrathoracic lesions have become almost negligible. This development was made possible by less invasive maneuvers such as computed tomography-guided (CT-guided) biopsy, thoracoscopy or video-assisted thoracoscopy, and bronchoscopy. CT-guided percutaneous lung biopsy was first reported in 1976. AIM OF STUDY: The aim of the study is to report our experience with CT-guided transthoracic biopsy. MATERIALS AND METHODS: Patients with clinical and radiological evidence of intrathoracic mass were counseled and consent obtained for the procedure. They were positioned in the gantry, either supine or prone. A scout scan of the entire chest was taken at 5 mm intervals. The procedure was carried out by the consultants and senior registrar. Following visualization of the lesion, its position in terms of depth and distance from the midline was measured with the machine in centimeter to determine the point of insertion of the trucut needle (14-18-G). The presumed site of the lesion was indicated with a metallic object held in place with two to three strips of plasters after cleaning the site with Povidone-iodine. After insertion, repeat scans were performed to confirm that the needle was within the mass. A minimum of 3 core cuts was taken to be certain that the samples were representative. The results were analyzed by the determination of means and percentages. RESULTS: Twenty-six patients underwent this procedure between 2011 and 2015. There were 15 males and 11 females (M:F = 1.4:1). The age range was between 30 and 99 years with a mean of 55 years. Histological diagnosis was obtained in 24 of the patients giving sensitivity of 92.3%. There were 3 mild complications giving a rate of 11.5%. The complications included a case of mild hemoptysis and two patients who had mild pneumothoraces which did not require tube thoracostomy. CONCLUSION: CT-guided biopsy is a reliable procedure for obtaining deep-seated intrathoracic biopsies with high sensitivity and minimal complication rate.

Factors affecting interest in cardiothoracic surgery among junior surgical residents in Nigeria.

OBJECTIVE: A survey was undertaken to determine the factors that affect interest in cardiothoracic surgery (CTS) among junior surgical residents in Nigeria. METHODS: A cross-sectional study was done using a pilottested, 56-item, semi-structured questionnaire, which was filled in by 238 junior surgical residents in accredited hospitals in Nigeria. RESULTS: Few of the respondents (8.4%) were committed to specialising in CTS. A minority of them, 28.2 and 2.1%, had assisted in major thoracic procedures and open-heart surgeries, respectively. The relationship between the level of training, rotation in CTS in junior residency and interest in CTS were statistically significant (p < 0.05). The main important factors responsible for the low interest in CTS include the lack of equipment (92%), limited training positions (64.9%), poor or lack of exposure in CTS as a junior resident (63%) and in medical school (58.8%). CONCLUSION: There is a dire need to provide facilities and training opportunities to improve the cardiothoracic workforce in Nigeria.

Vascular surgeries in West Africa: challenges and prospects.

BACKGROUND: The field of vascular surgery is evolving in sub-Saharan Africa but the practice is bedeviled by lack of expertise and infrastructure challenges. The consequences are a low volume of operations and a dearth of data. Available data are not representative of the wider picture, therefore, this study was undertaken to evaluate the practice of vascular surgery in a tertiary institution, in the light of the prevailing challenges. METHODS: Data from all patients with vascular-related pathologies managed in our surgical outpatient clinic and accident and emergency wards were obtained from the clinic and in-patient records from January 2008 to December 2012. Age, sex, diagnosis, treatment, and complications were noted. There were 73 patients comprising 45 (61.6%) males and 28 (38.4%) females. The age range was 1-90 years (mean 43.5 years). RESULTS: The pathologies managed included end-stage renal disease (n = 36, 49.3%), nontraumatic and posttraumatic aneurysms (n = 13, 17.8%), vascular trauma (n = 12, 16.4%), peripheral vascular disease (n = 5, 6.9%), congenital vascular malformations (n = 4, 5.5%), and thrombotic diseases (n = 3, 4.1%). Fifty-four (74.0%) surgeries were performed, with a complication rate of 5.5% and 2.7% mortality. CONCLUSIONS: The practice of vascular surgery in Zaria, Nigeria, is fraught with challenges. The gap created by the dearth of skilled vascular surgeons is filled by competent cardiothoracic surgeons. Infrastructure decay and lack of prostheses limit the number and variety of operable cases. These challenges result in preventable morbidity and mortality.

Indications and complications of tube thoracostomy with improvised underwater seal bottles.

BACKGROUND: Tube thoracostomy is a lifesaving and frequently performed procedure in hospitals where the expertise and necessary tools are available. Where the ideal drainage receptacle is unavailable, the underwater seal device can be improvised with bottled water plastic can especially in emergency situations. AIMS AND OBJECTIVES: To determine the frequencies of the various indications and complications of tube thoracostomy with improvised underwater seal. MATERIALS AND METHODS: A cross-sectional study with a structured proforma was used for assessment over a 3-year period (May 2010-April 2013). The proforma was filled at the time of the procedure by the performing surgeon and patients were followed up with serial chest X-rays until certified cured. A 1.5 L bottled water container was used as the underwater seal receptacle. The data was analysed with SPSS 15 software program. RESULTS: A total of 167 patients were managed. There were 106 (63.5%) males and 61 (36.5%) females. The mean age was 34.85 ± 16.72 with a range of 1-80 years. The most frequent indication was for malignant/paramalignant effusion, 46 (27.5%). Others were trauma, 44 (26.3%), Parapneumonic effusion, 20 (12%), postthoracotomy 14 (8.4%), empyema thoracis 12 (7.2%), heart disease and tuberculous effusion 11 (6.6%) each, pneumothorax 8 (4.8%) and misdiagnosis 1 (0.6%). A hundred and one (60.5%) of the procedures were performed by registrars, 41 (24.6%) by consultants, house officers 15 (9%) and senior registrars 10 (6%). The overall complication rate was 16.8% with the more frequent complications been empyema (5.6%) and pneumothorax (3.6%). The average duration of tube placement was 13.02 ± 12.362 days and range of 1-110 days. CONCLUSION: Tube thoracostomy can be a relatively safe procedure with acceptable complication rates even with improvised underwater seal drainage bottles.
