Misplaced central venous catheter in carotid artery during emergency surgery for the total correction of tetralogy of fallot of an adolescent boy

Ultrasound-guided central venous cannulation is now considered as the standard of care, and this has largely replaced blind central venous cannulation using anatomical landmarks. We are reporting a case of inadvertent placement of central venous catheter in the right common carotid artery with the use of ultrasound guidance during emergency surgery for the total correction of Tetralogy of Fallot (ToF). This patient luckily had a favourable outcome despite this inadvertent catheter placement which was not recognised even after completion of surgery .The patient also received drug infusions of inotropes and vasopressors through this malplaced central line into the aorta. The possible mechanism, consequences, prevention and management of this inadvertent cannulation are discussed in this report

Giant ganglioneuroma in a 5-year child

ABSTRACT We report a 5-year boy presenting with pain in the lower chest and upper abdomen. On evaluation with computed tomography scan of the chest, he was found to have a large 16 x 14 cm posterior mediastinal mass compressing the inferior vena cava and liver, and shifting the heart to the opposite side. Tumor was approached via right postero-lateral thoracotomy and dissected off from esophagus, heart, inferior vena cava and lungs. The entire tumor was resected without any complications. Postoperative course was unremarkable. Resection of the tumor was successful. The histopathology showed it to be giant ganglioneuroma with no evidence of malignancy

Repair of ascending aortic pseudoaneurysm eroding through the sternum

In reoperation for an ascending aortic pseudoaneurysm eroding through the sternum, a left ventricular vent allows careful unhurried sternal division under deep hypothermic circulatory arrest. We repaired ascending aortic pseudoaneurysms in 2 patients who had undergone aortic valve implantation 6 and 21 months earlier. A minithoracotomy was made in the left 5th intercostal space, and a vent was placed in the left ventricular apex. Repair was accomplished with a bovine pericardial patch reinforced with a Teflon felt strip. Both patients made an uneventful recovery with good functional status at discharge at the 8- and 18-month follow-up

Perioperative glycemic control and its outcome in patients following open heart surgery

Background: Diabetes is not uncommon in patients requiring cardiac surgery. These patients have a higher incidence of morbidity and mortality. Subsequently, diabetes represents a major medico-economic problem in both developed and developing countries. This study was designed to observe the association between glycemic control and outcome of patients after open heart surgery in adult population.Materials and methods: Data was collected retrospectively in all patients who underwent open cardiac surgery (coronary artery bypass grafting, valve, or bypass grafting with valve surgery) and survived 72 hours postoperatively and had diabetes. The study was conducted from January 2015 to December 2016.Results: Of the 129 patients included in the study, male dominated 101 (78.3%). Most frequent surgery was coronary artery bypass grafting (CABG) 123 (95.3%), CABG plus aortic valve replacement 4 (3.1%), and CABG plus mitral valve replacement 2 (1.6%). Considering diabetes, only 3 (2.3%) were on diet control, 112 (86.8%) on oral hypoglycemic agents (OHA), whereas 9 (7%) had control on both insulin and OHA. Only 5 (3.9%) had type I diabetes. The mean fasting blood sugar (FBS) was 154.58 g/dl, and the mean duration of diabetic mellitus was observed 12.32 years. Microvascular and macrovascular complications were 26/129 (20.16%) and 17/129 (13.17%), respectively. Total 75 (58.1%) patients did not require insulin and 54 (41.9%) were treated with insulin intraoperatively to keep the blood glucose level less than 200 g/dl. Cardiac arrhythmias were frequent in the insulin group (P \u3c 0.05), which was also associated with increased stay in the cardiac intensive care unit.Conclusion: Inadequate glycemic control during open cardiac surgery can possibly lead to increased perioperative morbidity and mortality and with decreased long-term survival and recurrent ischemic events. Therefore, aiming for blood glucose levels around 140 mg/dl appears reasonable. Further studies are required to define specific glucose ranges for a clearer definition of recommended blood glucose goals in postoperative cardiac patients for the best outcomes in patients with diabetes mellitus

Minimally invasive technique of placing a dual chamber permanent pacemaker in children

Objective: To share the experience of a minimally invasive technique in the implantation of a dual chamber permanent pacemaker in paediatric population. Methods: The retrospective study was conducted at Aga Khan University Hospital, Karachi, and comprised data of patients aged up to1 6 years who underwent epicardial dual chamber permanent pacemaker insertion via xiphisternal incision between April 2011 and August 2016. Demographic data included age, weight and gender of the patient. Indications for pacemaker insertion, electrocardiography findings, concomitant cardiac procedures and procedural complications were reviewed. Pacemaker thresholds and impedance at the time of implantation and throughout the course of follow-up were extracted from the clinical data. Results: Of the 10 patients, 5(50% were males and 5(50%) were females. The overall mean age was 3.43.8 years range:1 month - 13 years. The mean weight at the time of operation was 11.4 6.8 kg range: 4.3 27 kg. Indications for permanent pacemaker insertion included postoperative advanced or complete atrioventricular block in 7(70% and complete congenital heart block in 3(30% There was no reported morbidity. Conclusion: Dual chamber permanent pacemaker insertion via xiphisternal incision was found to be of benefit to the patients and the surgeons alike

Giant aortic root aneurysm associated with postductal coarctation of aorta

The aorta is a large blood vessel that carries blood from the heart to the rest of thebody. The aortic root consists of the aortic valve and the openings for thecoronary arteries (the coronary ostia). An aortic aneurysm is an abnormal bulgein the wall of the aorta. If an aneurysm develops in the aortic root, the aorta candilate and the aortic valve can leak. If the aneurysm continues to expand, it canrupture and can cause life-threatening internal bleeding.Aneurysms of the aortic root are often due to degenerative disease of media.Aneurysm of the aortic root often affects patients in their second to fourthdecades of life. These aneurysms can cause aortic insufficiency, dissection,and/or rupture.Small and slow-growing thoracic aortic aneurysms may not everrupture, but large, fast-growing aneurysms may rupture.Depending on the size and growth rate of aortic aneurysm, treatment may varyfrom watchful waiting to emergency surgery. Ideally, surgery for a thoracic aorticaneurysm can be planned if necessary. Current guidelines recommend surgicaltreatment when the diameter of the aneurysm exceeds 50 mm. Here we report acase of thoracic aneurysm with postductal coarctation of aort

Primary melanotic schwannoma with typical histology

Abstract We present a case of a 17-year male with a soft tissue density spreading from the neural foramina (T3) of the spinal cord and involving the right upper thoracic cavity. We managed the patient through surgical intervention and resected the complete tumor. Gross definition and microscopic findings of the resected tissue revealed the definitive diagnosis of melanotic schwannoma. The histological characteristics in this case were very specific and harbour an important diagnostic clue for this rare disease. Malignant melanoma was ruled out on the basis of histological findings. The patient recovered completely and was healthy on one-year follow-up

Management of penetrating injury to thoracic inlet and lower neck with retained foreign body using video assisted thoracoscopic surgery

Penetrating neck and chest injuries are a common form of occupational injuries. We hereby report a unique case in which a metallic rod had penetrated the left chest and neck of a plastic factory worker. The patient was vitally stable when he presented to Emergency Room. Chest X-ray was performed and the patient was rushed to the operating room. VATS (video assisted thoracoscopic surgery) and neck dissection was done for retrieval of the metallic rod. On table, endoscopy was also done to rule out injury to oesophagus. No injury to vital structures was found and the subsequent recovery was uneventful

Cervical mediastinoscopy in the diagnosis of lymphadenopathy in South Asia.

Abstract We planned to determine the clinical utility and safety of mediastinoscopy in the pathologic diagnosis of mediastinal lymphadenopathy and to determine disease patterns in a tertiary care setting in Karachi. The retrospective review comprised record of patients who underwent mediastinoscopy over 25 years between July, 1990 and August, 2015. Of the 122 patients, records were complete for 88(72%). Mean age was 42.5±12.9 years and 55(62.5%) were male. Overall, 60(68.2%) patients had benign inflammatory diseases; 25 (28.4%) had lymphoma or lung cancer which was accurately staged; 26(29.5%) had tuberculosis; 13(14.8%) sarcoidosis; and 11 (12.5%) had concomitant tuberculosis and sarcoidosis. No mortality or significant morbidity was recorded. Mediastinoscopy was useful in staging bronchogenic carcinoma and influenced the management in this series. It was found to be accurate in the diagnosis of other malignant as well as benign mediastinal pathologies, all of which were treatable

Delayed presentation of forgotten thyroid goiter - 25 years after thyroidectomy

Forgotten goiter is a rare occurrence (2 - 16% of retrosternal thyroid cases) that depicts recurrence of retrosternal thyroid mass due to growth of remnant thyroid tissue overlooked during an initial thyroidectomy. The patient is a 59-year female who presented with dyspnea and stridor 25 years after total thyroidectomy. She was diagnosed as having a mediastinal mass on radiographic imaging. There were only localized pressure symptoms due to mass effect. The mass was excised employing an extra-cervical approach and using a partial sternotomy. The profuse extension of thyroid tissue, adherent to vital structures in the thorax and the extra-cervical thyroidectomy was a novel experience. The mass was completely excised and the patient\u27s symptoms alleviated after the surgery. The patient recovered without any complications and there was no recurrence at 1 year of follow-up
