Scourge of Peripheral Artery Disease in a Low-Income-Setting: The Role of VascularSurgery

Background: Peripheral artery disease (PAD) is a progressive disorder characterized by stenosis and/or occlusion of large and medium-sized arteries, other than those that supply the heart (coronary artery disease, CAD) or the brain (cerebrovascular disease). It is increasingly becoming a challenge in developing countries owing to poverty and ignorance. Objective: To review the scourge of peripheral artery diseases in our institution in a low-income setting with a view to determining the role of a vascular surgeon. Materials and method: Over a period of 15 years (2006 to 2021), patients with documented PAD were reviewed. Data of the patients were retrieved from the record department and such data included demography, aetiology/risk factors, clinical features and investigative parameters as well as modes of treatment especially vascular surgery. Results: There were 35 patients which comprised 20 males and 15 females with male to female ratio of 4:3. Age range affected most was 71-80 years. Aetiologically, artherosclerosis was dominant. Leriche Fontaine classification used in clinical evaluation showed that type III was dominant. 6 Ps (pain, pulselessness, paralysis, paraesthesie, pallor and poikilothermia) of vascular ischemia were evident. Doppler/duplex ultrasound and computer angiography were used in diagnosis. Medical and or surgical treatments were used in patients' management. Vascular and or orthopedic surgery played significant role. Conclusion: PAD affects the lower extremities more commonly than the upper extremity vessels especially in the elderly leading to intermittent claudicationn which is the most recognized symptomatic subset of lower extremity PAD. Morbidity and mortality emanating from inadequate revascularization are burden to emerging economy like ours.

Management of malignant pleural effusion (MPE) in a Tertiary Hospital in a low-income-country: challenges and prospects

Background: In the West African sub-region, significant morbidity and mortality are known to affect patients with malignant pleural effusion (MPE) but are highly under reported unlike USA, Europe or South Africa. Aim/Objective: To review cases of MPE in our tertiary hospital in the last 13 years with a view to determining the challenges and prospects. Materials and Method: This is a retrospective study spanning over a decade from January, 2007 to December, 2019. Malignant pleural effusion from various neoplasms constitutes the commonest thoracic malignancy in our tertiary hospital. After 13 years of management of such patients, we reviewed the datafrom the hospital record's department. The data obtained were demography, aetiology, total number of pleural fluid specimens for cytology and pleural biopsies submitted for histology, pleurodesis and other treatment modalities. Result: 211 patients with MPE were admitted and managed during the period under review. Of these numbers, 135(64.0%) were confirmed cytologically positive (MPE). 76(36.0%) tested falsely negative and were initially regarded as paramalignant, later confirmed MPE. The age affected was from 7 to 81 years with a mean of 44 years. Of 211 patients with MPE, 94 were males while 117 were females, with a male to female ratio of 4:5. Aetiologically, metastatic breast cancer was the highest followed by advance lung cancer. Conclusion: Submission of insufficient samples resulted in false negative cytology. Review of recurrent pleural effusion and exophytic tumour at the sites of CTTD resulted in late diagnosis of MPE. Additionally, prolonged hospital stay awaiting CTTD and cytology results are among the challenges

GIANT PSEUDOANEURYSM OF A SPLANCHNIC ARTERY; A Case Report.

A true aneurysm is defined as an enlargement of an artery resulting in a diameter more than 1.5 times the anatomic size. It can be fusiform when it covers the entire perimeter of the vessel, or saccular when it bulges on one side of the artery. The pseudoaneurysm is a pulsating encapsulated haematoma in communication with the lumen of the ruptured vessel,which affects the the intima and the media and which is stopped from developing by the adventitia and the surrounding connective tissue. Geographically, aneurysm can be broadly divided into intracranial and extracranial types.While the neurosurgeon manages the intracranial types, the vascular surgeon manages the extracranial types. Vascular surgeons also do divide the extracranial types into central (abdominal-aorto-iliac, thoracic including ascending, transverse aortic arch and descending), peripheral (extremities) and visceral (splanchnic arteries). Splanchnic artery aneurysm includes the coeliac, superior mesenteric, inferior mesenteric arteries including their branches. Of all intra-abdominal aneurysms, only around 5% are due to the splanchnic arteries,which could be either true or pseudo. The prevalence has been estimated at 0.1-0.2%.

The profile of chest injuries in a southeastern Nigeria teaching hospital, a 10-year experience.

BACKGROUND: Globally, major chest injuries have both high morbidity and mortality. A detailed study of chest injuries in south-eastern Nigeria is here presented. AIMS: To determine the incidence, the predisposing factors, the pattern of presentation and the outcome of management of chest injuries. MATERIALS AND METHODS: This is a retrospective study spanning a period of 10 years (2002-2011). The medical records of all patients with documented chest injuries that presented to our hospital within the period under review, were retrieved and analysed, by simple arithmetic percentages. RESULT: A total of 402 patients (average of 40/year) with the age ranges in the spectrum of 0-10 and 81-90 years, with a mean of 2.2 were found. Gender-wise, 301 males (74.9%) and 101 females (25.1%) were affected. The aetiological or the predisposing factors were blunt chest injuries (61.2%) and penetrating chest injuries (38.8%). In the pattern of presentation, haemothorax (20.9%), haemopneumothorax (16.2%), pneumothorax (17.4%) including simple, open and tension types as well as multiple ribs fractures (7.7%) constituted the majority. In the management strategies, conservative methods were mainly used. The outcome ranged from very good to fair. CONCLUSION: The management of chest injuries in our sub-region like any other developing countries is very much challenging. Concerted efforts are needed to overcome the burden it imposes.

Right colon interposition in corrosive esophageal long segment stricture: our local experience.

BACKGROUND: Aim of our study is to highlight technical details in pedicled right colon interposition locally in cases of long segment corrosive esophageal stricture. Lesion results from cicatrization of burns wound inflicted by chemicals. Restoration of swallowing is of paramount importance. MATERIALS AND METHODS: It was a retrospective study involving adult and adolescent patients who had surgery because of corrosive esophageal stricture between January 2001 and December 2010. Hospital records were reviewed for age, sex, radiological findings, detail of anesthesia, operative procedure, and follow up. The steps which included mobilization of colon with intact marginal blood supply, safeguarding the middle colic artery that forms the pedicle, and doing three anastomoses that were leak proof were ascertained. RESULT: There were 12 males (70.5%) and six females (29.4%) and age ranged from 14 to 45 years. Caustic soda caused the problem among 10 (58.8%) patients while liquid acid battery was involved in three (17.6%) patients. The rest were distributed equally between native concoction and unknown substance. All were done under general anesthesia and mean duration of the procedure was 306.8 ± 54.6 min with an average intra operative blood loss of 823.1 ± 428.5 m. Sixteen (94.1%) had successful pedicle isolation and 15 (82.3%) patients had neither dysphagia nor reflux at follow-up. CONCLUSION: Securing a pedicled right colon based on middle colic artery was a critical step. This surgical technique should be used to restore swallowing among patients with long segment esophageal stricture.

The challenges facing the management of arterial aneurysm in UNTH, Enugu.

BACKGROUND: The management of arterial aneurysm either central or peripheral has undergone evolution over the past decades. We encounter both true and pseudo aneurysm on regular basis with its complications: OBJECTIVE: To assess the challenges of managing arterial aneurysm at UNTH, Enugu in view of the health complications of the condition. METHOD: Medical records of all patients with documented arterial aneurysm over a 5-year period (2007-2011) were reviewed. Data collected and documented included patients' demographics, type of vessels involved, investigative tools used in confirming the diagnosis, type of treatment, outcome and length of hospital stay. RESULT: Atotal of 37 patients were managed for arterial aneurysm during the period under review. These consisted of 24 males (64.9%) and 13 females (35.2%). Age range was 11-78 years with a mean of 2.4 years. Central aneurysms involved ascending, arch and descending aorta as well as abdominal aorta. Peripheral ones affected femoral, axillary, brachial, and popliteal artery. The central aneurysms with the exception of abdominal aortic aneurysms were managed conservatively. Those that failed conservative management were referred to centres with expertise and facilities for on pump surgery. The peripheral ones in addition to abdominal aortic aneurysms were managed operatively with good outcome. The challenges identified in the management included non-availability of on pump expertise and prosthesis, late presentation of patients, under utilisation of CT and or MRI, poor compliance to antihypertensive drugs and poor follow up. CONCLUSION: Intervention in arterial aneurysms is the gold standard but not yet easily available and affordable at this centre. The challenges that have been identified are real and need to be addressed in order to deliver optimal care to patients within our domain. Efforts are underway in tackiling them.

Traumatic diaphragmatic rupture through the central tendon with herniation of the stomach and coils of small bowel into the pericardial cavity.

UNLABELLED: Traumatic diaphragmatic rupture through the central tendon with herniation of the stomach and coils of small bowel into the pericardial cavity. METHOD: Case note of a patient managed for traumatic diaphragmatic rupture through the central tendon with herniation of the stomach and coils of small bowel into the pericardial cavity was used with a review of relevant literature. SUMMARY: A 49-year old civil engineer who presented with 2-year history of easy fatigability and palpitations as well as a 6-month history of hypertension and was initially managed as a case dilated cardiomyopathy to rule out incipient CCF secondary to hypertension, was evaluated and found to have chronic diaphragmatic hernia through the central tendon with evisceration of the stomach and coils of the small bowel into the pericardial cavity. Though there was history of motor vehicle crash preceding the development of the symptoms, but the long history of effort dyspnoea and palpitations added to enlarged cardiac silhouette on posterior anterior chest x-ray, a diagnostic challenge was posed which was resolved by thoracoabdominal CT scan. Patient had left sided posteriorlateral thoracotomy via 7h intercostal space followed with reduction of thq stomach and coils of small bowel after careful adhesiolysis and repair of the defect in double layers. CONCLUSION: High index of suspicion is very important in the diagnosis of diaphragmatic central tendon injury considering the rarity of the injury and diagnostic challenges it poses in chronic form. However, where the facilities are available, CT scan and 2-D echo will most of the time clinch the diagnosis; also is upper gastrointestinal series.
