Case report: Navigating the challenges: successful mechanical thrombectomy in a case of persistent primitive hypoglossal artery.

Persistent primitive hypoglossal artery (PPHA) is a highly uncommon abnormal connection between the internal carotid artery (ICA) and vertebral artery (VA), with reported incidences ranging from 0.027 to 0.26%. Attempting endovascular intervention in such cases presents a considerable challenge as it carries a higher risk of embolization and other procedure-related complications that may affect a wide area of the brain. We present a case study involving the utilization of mechanical thrombectomy (MT) to treat an ischemic stroke in the M1 segment of the middle cerebral artery (MCA) despite the presence of PPHA. Performing mechanical thrombectomy in an anomalous vascular connection is feasible; however, it necessitates heightened vigilance, thorough knowledge of the anatomy, and utmost caution.

Complications Associated with Permanent Internal Jugular Hemodialysis Catheter: A Retrospective Study.

Introduction A significant increase in patients with end-stage renal disease has been observed currently in our community. Kidney transplantation is the most promising cure but the problem is that large numbers of people are not good candidates for transplantation. Hemodialysis is the next appropriate medication for such patients and for patients with end-stage renal disease, who have no chance for transplantation. Morbidity and mortality are the consequences of vascular access complications. Local data related to the complication rate of permanent hemodialysis catheters is not available. The current study examines the complication rate in people due to permanent intrajugular hemodialysis catheterization. Materials and methods The study has been conducted in Dr Ziauddin University Hospital, Karachi. The dataset consists of 212 patients who had gone through jugular catheterizations for hemodialysis at this hospital from the year 2014 to the year 2015. A descriptive method has been chosen for obtaining appropriate results. Complications have also been categorized as early or late. Results Complications have been detected in around 24% of the patients from the dataset. Among these complications, infection has the highest percentage (around 13%) while 4% percent of patients have a failed puncture. The others have venous thrombosis, catheter thrombosis, hematoma, wrong canulation, and hemothorax and pneumothorax problems. Conclusion The study concludes that the placement of a permanent hemodialysis catheter in the internal jugular vein has a low complication rate. In addition, the method is safe and easy. So, it can be said that the internal jugular vein is a reliable and preferred route for hemodialysis catheterization.

Diagnostic Accuracy of Ultrasound B scan using 10 MHz linear probe in ocular trauma;results from a high burden country.

OBJECTIVE: To study the diagnostic accuracy of Ultrasound B scan using 10 MHz linear probe in ocular trauma. METHODS: A total of 61 patients with 63 ocular injuries were assessed during July 2013 to January 2014. All patients were referred to the department of Radiology from Emergency Room since adequate clinical assessment of the fundus was impossible because of the presence of opaque ocular media. Based on radiological diagnosis, the patients were provided treatment (surgical or medical). Clinical diagnosis was confirmed during surgical procedures or clinical follow-up. RESULTS: A total of 63 ocular injuries were examined in 61 patients. The overall sensitivity was 91.5%, Specificity was 98.87%, Positive predictive value was 87.62 and Negative predictive value was 99%. CONCLUSION: Ultrasound B-scan is a sensitive, non invasive and rapid way of assessing intraocular damage caused by blunt or penetrating eye injuries.

Diagnostic cut-off levels of plasma brain natriuretic peptide to distinguish left ventricular failure in emergency setting.

OBJECTIVE: To determine the diagnostic cut-off values of brain natriuretic (BNP) peptide to establish left ventricular failure in patients presenting with dyspnoea in emergency department. STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: Ziauddin University Hospital, Karachi, from July to December 2011. METHODOLOGY: BNP estimation was done on Axysm analyzer with kit provided by Abbott diagnostics, while the Doppler echocardiography was done on Toshiba istyle (UICW-660A) using 2.5 MHz and 5.0 MHz probes. Log transformation was done to normalize the original BNP values. A receiver operating curve was plotted to determine the diagnostic cut-off value of BNP which can be used to distinguish CHF from other causes of dyspnoea. Statistical analysis was performed by SPSS version 17. RESULTS: A total of 92 patients presenting with dyspnoea in the emergency department were studied. There were 38/92 (41.3%) males and 54/92 (58.7%) females, and the average age of the study population was 64 ± 14.1 years. These patients had BNP levels and Doppler echocardiography done. The average BNP was found to be 1117.78 ± 1445.74 pg/ml. In log transformation, the average was found to be 2.72 ± 0.58. BNP value of 531 pg/ml was found to be the cut off to distinguish between cardiogenic and non-cardiogenic causes of dyspnoea. CONCLUSION: BNP value of 531 pg/ml can distinguish CHF from other conditions as a cause of dyspnoea in emergency.
