Advanced Imaging Techniques for Complex Endovascular Aortic Repair: Preoperative, Intraoperative and Postoperative Advancements.

BACKGROUND: Endovascular aortic repair (EVAR) requires extensive preoperative, intraoperative, and postoperative imaging for planning, surveillance, and detection of endo-leaks. There have been manyadvancements in imaging modalities to achieve this purpose. This review discussed different imaging modalities used at different stages of treatment of complex EVAR. METHODS: We conducted a literature review of all the imaging modalities utilized in EVAR by searching various databases. RESULTS: Preoperative techniques include analysis of images obtained via modified central line using analysis software and intravascular ultrasound. Fusion imaging (FI), carbon dioxide (CO2) angiography, intravascular ultrasound, and Fiber Optic RealShape (FORS) technology have been crucial in obtaining real-time imaging for the detection of endo-leaks during operative procedures. Conventional imaging modalities like computed tomography (CT) angiography (CTA) and magnetic resonance (MR) angiography are still employed for postoperative surveillance along with computational fluid dynamics and contrast-enhanced ultrasound (CEUS). The advancements in artificial intelligence (AI) have been the breakthrough in developing robust imaging applications. CONCLUSIONS: This review explains the advantages, disadvantages, and side-effect profile of the abovementioned imaging modalities.

Expediting the Management of Suspected Cauda Equina Syndrome (CES) in the Emergency Department Through Clinical Pathway Design at a District General Hospital: A Quality Improvement Project.

BACKGROUND: Cauda equina syndrome (CES) is an uncommon condition that occurs due to compression of the terminal portion of the spinal cord. Early recognition and intervention in CES are crucial for an improved prognosis. Delayed diagnosis and action may lead to irreversible adverse effects, i.e., permanent disability, and in some circumstances can lead to litigation. AIM:  The aim of this quality improvement project (QIP) was to identify areas for improvement and expedite the management of suspected CES patients presenting to the hospital. MATERIAL AND METHODS: This was a retrospective study in which patients admitted to the Poole district hospital were analyzed in three groups with more than 50 patients in each subset group. The first group was audited from 1st October 2020 to 27th November 2020; a re-audit on the second group of patients was done from 1st June 2021 to 16th July 2021; the third group was re-audited from 1st of January 2022 to 31st of March 2022. RESULTS: There were a total of 168 patients in all audit groups, of whom 71% were female. The mean time from getting triaged to having an MRI improved from 13hrs 54mins to 10hrs 39mins. The total inpatient length of stay (LOS) of less than 24 hours was 28% in the first cycle and improved to 54.4% by the third cycle of the audit. Eight patients exhibited a diagnosis of cauda equina syndrome (CES) and were sent to the tertiary care center. CONCLUSIONS: This quality improvement project identified delays in requesting the MRI for the diagnosis of CES and was addressed by ED booking the scans directly. This, in turn, reduced the length of stay in the hospital for patients who did not have cauda equina syndrome.

Effect of COVID-19 on the Cardiothoracic and Vascular Surgery Procedures Mix at a Tertiary Care Hospital.

Objective To assess the effect of the COVID-19 pandemic on the cardiothoracic and vascular surgery procedures volume at a tertiary care hospital. Materials & Methods This cross-sectional retrospective study was carried out at a tertiary care hospital's Cardiothoracic and Vascular Surgery department. All the four-year surgical procedures data were reviewed from August 2017 to August 2021. After extracting data from the hospital database software, a databank was generated in SPSS version 24.0. Average cases per month were calculated, and the data were stratified into three groups, Pre-COVID, COVID, and Post-COVID. Tables and charts were generated for the representation of data. Results The total number of patients that underwent cardiovascular and thoracic procedures during the years 2017-2021 were 3,624, with male predominance (71.5%). Procedures were divided into Pre-COVID (68.5%), COVID (15.2%) and Post-COVID (16.3%) groups. Coronary Artery Bypass Grafting (CABG) was the most common procedure throughout the study duration (56.8%) and during the COVID-19 pandemic (29 procedures/month). Congenital Heart Surgeries (16.6%) and Valvular surgeries (11.5%) were next on the list. However, congenital heart surgeries were most affected during the pandemic (16 to 5 procedures/month). The average number of surgeries per month peaked at 2017 (135 procedures/month) and after that declined to its low of 46/month during the COVID-19 pandemic (The year 2020). Conclusion Cardiothoracic and Vascular Surgeries have significantly decreased during the COVID-19 pandemic, especially the Coronary Artery Bypass (CABG) and Congenital Heart Surgeries. CABG procedures, however, remained the highest performed surgery even during the pandemic due to their emergent nature. Thoracic, vascular, and combined surgeries have stayed almost constant. The year 2020 (COVID-19 year) saw the lowest number of surgeries performed per month. An uprising trend in the number of surgical procedures is seen in the post-pandemic time (2021).
