Long-Term Impact of COVID-19 Related Disruption of National Health Service Elective Services on Emergency Major Lower Limb Amputations.

BACKGROUND: The COVID-19 pandemic has affected the healthcare systems worldwide since the dawn of 2020. In March 2020, the United Kingdom government announced the first national lockdown which severely disturbed all National Health Service (NHS) healthcare elective services. Our aim is to assess the long-term impact of COVID-19 related disruption of NHS elective services on emergency major lower limb amputations (MLLAs). METHODS: Patients' data for emergency MLLA for critical limb-threatening ischemia and diabetic foot infections performed at Aberdeen Royal Infirmary was collected through Trakcare and divided into the control prepandemic group (April 2018-March 2020) and the pandemic group (April 2020-March 2022). The statistical analysis was conducted using the IBM SPSS software (v28.0.1.1 [14]). RESULTS: A total of 358 patients underwent MLLA and 206 (57.5%) of these had diabetes mellitus. There was a 17% increase in the number of urgent referrals and every 1 in 5 of these finally underwent an amputation. There was an increase in the absolute number of Above- and Below-Knee amputations. There was a statistically significant increase by 33% in emergency MLLAs during the pandemic period (P < 0.05). A total of 165 postoperative deaths up to December 2022 were recorded with 30-day mortality rate of 7.26% (n = 26). CONCLUSIONS: NHS vascular management groups should update themselves with evolving technologies to optimize the care provided during future unprecedented times. Furthermore, more effective measures should also be implemented to avoid delayed presentations, which can potentially lead to higher rates of major limb amputations.

Novel conformable stent-graft repair of abdominal aortic aneurysms with hostile neck anatomy: A single-centre experience.

OBJECTIVES: Abdominal aortic aneurysms (AAAs) demonstrating hostile neck anatomy (HNA) are associated with increased perioperative risk and mortality. A number of these patients are not suitable for standard endovascular aneurysm repair (EVAR) and are high risk for open surgery. We present our experience with the first implantations in Scotland of a novel conformable aortic stent-graft designed to overcome some of the challenges of HNAs. METHODS: From May 2018 to March 2022, 24 consecutive patients with non-ruptured AAAs demonstrating HNAs (neck length < 15 mm, or angulation > 60°) were treated with GORE Excluder Conformable AAA endoprosthesis (CLEVAR) (CEXC Device, W.L. Gore and Associates, Flagstaff, AZ, USA) at a Scottish vascular centre. We assessed clinical outcomes and technical success of CLEVAR during deployment, primary admission and the post-operative period at 3- and 12-month clinical follow-up alongside CT angiography. RESULTS: Twenty-four patients (20 males, mean age 75.6) were included. Primary technical success of proximal seal zones and CLEVAR deployment (no type 1/3 endoleaks, no conversion to open repair, AAA excluded and patient leaving theatre alive) was achieved in 100% of patients. All patients were alive and clinically stable at 3- and 12-month follow-up. There were five patients requiring re-intervention; at the 3-month follow-up, one patient (4.2%) developed a type 1b endoleak requiring graft limb extension, one patient developed a right common femoral artery dissection requiring open repair and one patient required a limb extension of the right iliac limb due to risk of developing a type 1b endoleak. At the 12-month follow-up, two patients required embolization of type 2 endoleaks and no patients demonstrated type 1 or type 3 endoleaks.Conclusions: In-hospital and post-operative 3- and 12-month clinical and angiographic outcomes demonstrate safety and efficacy with CLEVARs in treating unruptured AAAs with HNA. Further research involving larger heterogenous sample sizes is warranted to determine long-term clinical outcomes.

Surgical Excision of a Contained Rupture of an Inferior Mesenteric Aneurysm.

Inferior mesenteric artery (IMA) aneurysms represent the minority of visceral aneurysm presentations. A 57-year-old female was admitted with a symptomatic IMA aneurysm secondary to atherosclerotic disease. She was treated with open excision which revealed a contained ruptured of a true aneurysm. This case highlights the challenges of an accurate preoperative diagnosis of IMA aneurysm and the correct position of the recent guidelines on visceral aneurysms issued by the Society of Vascular Surgery (SVS).

Improving health behaviors in patients with peripheral arterial disease - A pilot study of supported self-management.

PURPOSE OF THE RESEARCH: This pilot study reports the feasibility of a future randomized controlled trial (RCT) investigating the effect of supported self-management through low-intensity psychological intervention in patients with peripheral arterial disease (PAD) resulting in claudication. The study protocol, measurement instrument, data collection, and analysis were evaluated. Clinical outcome measures include depression and anxiety scores, smoking cessation, activity (step count), weight, and quality of life. Both Quantitative and Qualitative data were collected to evaluate participant experience and the clinical impact of a supported self-management intervention delivered in a routine clinical setting. METHODS: Participants received an initial one to one assessment with a health psychologist. Demographic data and baseline clinical outcome measures were recorded. These included Hospital Anxiety and Depression Scale score (HADS), health-related quality of life questionnaire (EQ-5D-3 L), number of cigarettes smoked daily, weight/BMI, and daily step count. Participants each received an activity tracker to record daily step count and were followed up weekly to provide psychological input, including goal setting, overcoming barriers, and preventing relapse. Quantitative data collection was scheduled at baseline, 3 and 6 months (final follow-up). At the final follow-up, participants provided qualitative feedback reflecting upon their experience of the intervention and its impact. Descriptive statistical analysis and simple paired samples t-test were employed in data evaluation. RESULTS: The sample size was small (n = 30). Twenty-three participants were followed up to 6 months. Depression scores improved with statistical significance from baseline to 6-month follow-up. Eight participants stopped smoking (47% reduction); a further 9 greatly reduced their intake. A borderline statistically significant increase of daily step count was achieved between baseline and 6-month follow-up. In addition, positive weight loss trends were observed in a predominantly obese or overweight cohort. The qualitative feedback highlighted participants understood and embraced the information delivered regarding the importance of health behavior change. Participants were able to link tailored action plans with what mattered to them with the help of the Health Psychologist. CONCLUSION: This study embraces the contemporary ideology of enabling self-management of long-term conditions to improve clinical outcomes. As a pilot study, we have shown that an expanded, randomized controlled trial is both safe and feasible. A positive trend in clinical outcomes suggests this patient group may benefit from supported self-management through low-intensity psychological intervention, where other forms of early intervention have historically faltered.

Gallbladder necrosis and small bowel ischaemia following fenestrated endovascular aneurysm repair for juxtarenal abdominal aortic aneurysm: a case report.

Anatomical variation may result in unexpected complications after fenestrated endovascular aneurysm repair (FEVAR). We report a 78-year-old gentleman who was admitted for elective FEVAR procedure for a juxtarenal abdominal aortic aneurysm. Three days post-operatively, he deteriorated clinically. Computed tomography (CT) angiogram showed small bowel ischaemia and a replaced right hepatic artery originating from superior mesenteric artery. A necrotic gallbladder found during laparotomy required cholecystectomy following small bowel resection that required a relook for anastomosis and drainage of bile collection. He had prolonged ICU stay requiring treatment for multiple organ dysfunction then spent 4 weeks in hospital. Following multidisciplinary team approach in management of his complications during post-operative phase, he recovered well enough for rehabilitation and discharge home. Surveillance CT aorta at 1 month and 6 months post FEVAR showed satisfactory FEVAR appearance with no endoleak.

Images in surgical radiology: an unusual case of acute appendicitis within a femoral hernia.

We present a rare case of acute appendicitis within a femoral hernia, which was diagnosed preoperatively on CT scan.

Spontaneous recanalization of a middle cerebral artery occlusion with subsequent carotid endarterectomy.

We report the case of a 55-year-old man who presented with a left hemisphere stroke. The initial computed tomography scan demonstrated a cerebral infarct in association with a left middle cerebral artery occlusion. Carotid duplex ultrasound imaging revealed a surgical grade stenosis of the proximal left internal carotid artery; however, in view of the uncertain benefits of internal carotid endarterectomy in the face of ipsilateral middle cerebral artery occlusion, surgery was deferred. Subsequent surveillance by transcranial Doppler imaging and repeat computed tomography demonstrated spontaneous recanalization. The patient proceeded to carotid endarterectomy with no complications.
