RESUMEN
BACKGROUND: The aim of this meta-analysis is to determine the morbidity and mortality outcomes of adult patients with aortic arch disease managed with extra-anatomical bypass avoiding median sternotomy and cardiopulmonary bypass, with simultaneous or staged hybrid zone 1 endovascular aortic repair. METHODS: Systematic literature searches of the MEDLINE, EMBASE, and Cochrane databases were carried out to identify relevant studies on zone 1 hybrid arch repair. Extracted data were analyzed by random effects models. Primary outcomes included 30-day or in-hospital mortality. Longitudinal survival was analyzed up to 7 years from date of operation. Secondary outcomes included in-hospital morbidity, as well as late endoleak and reintervention. RESULTS: Twenty studies incorporating 348 patients were included. In-hospital or 30-day mortality was 10.1% (95% confidence interval, 6.7-14.9%). Overall operative technical success was 89.8% (83.7-93.8%). Early type 1 endoleak rate was 14.0% (7.4-24.7%). Stroke prevalence was 9.5% (6.1-14.3%). Spinal cord paraplegia prevalence was 3.8% (1.9-7.6%). Retrograde aortic dissection prevalence was 4.1% (1.5-10.6%). Survival at 1 year postoperatively was 77.2% (66.1-85.4%). Survival at 3 years postoperatively was 73.7% (59.2-84.4%). Survival beyond 4 years postoperatively (range 58-80 months) was 65.9% (53.6-76.4%). Late type 1 endoleak prevalence was 11.8% (5.5-23.7%). Overall rate of reintervention was 11.6% (6.4-20.1%). CONCLUSIONS: Zone 1 hybrid repair has evidence for satisfactory short- and long-term morbidity/mortality outcomes and may be considered as an alternative approach to aortic arch disease.

BACKGROUND: Whilst autologous vein conduits have been heralded as the first-line approach for patients undergoing lower limb bypass grafting procedures, patients with peripheral arterial occlusive disease may have exhausted venous options given prior use for cardiac surgery, varicose vein surgery, or lower limb revascularization. Hence, the use of a radial artery graft may serve as a viable alternative. METHODS: The systematic review was performed in accordance to the Preferred Reporting Items for Systematic Review and Meta-analysis guidelines. An electronic search was performed on the following databases: Medline (via PubMed); EMBASE; Cochrane library to search for relevant publications. A narrative analysis was conducted. RESULTS: Four publications were included in this review including two retrospective cohort studies, one case series, and one case report, with a total of 43 patients. The most common indication for lower limb bypass grafting was critical limb ischemia, and the radial artery was chosen as graft conduit, most commonly due to the absence of suitable arm or leg vein. There was one case of 30-day mortality and 11 reinterventions. CONCLUSION: Despite the encouraging results, the paucity of high-quality studies prevents the establishment of any firm conclusion. This warrants the need for appropriately conducted randomized controlled trials to compare the radial artery graft to autologous vein grafts and prosthetic grafts for lower limb bypass grafting.

BACKGROUND: Whilst the management of blunt traumatic thoracic aortic injury has seen a paradigm shift to an 'endovascular first' approach, the limitations of thoracic endovascular aortic repair remain. An inadequate proximal landing zone limits the use of thoracic aortic stent grafts and in an emergent polytrauma setting, aortic arch debranching via open surgery may not be practical or feasible. A wholly endovascular approach to debranching utilising 'off-the-shelf' stents and parallel graft techniques may represent a possible solution. Hence, we sought to perform a systematic review investigating the use of chimney graft techniques alongside thoracic aortic stenting in blunt traumatic thoracic aortic injury. METHODS: We performed the systematic review in accordance to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Searches were performed on Medline (PubMed), Web of Science and Scopus to identify articles describing the use of chimney grafts in traumatic aortic transection (PROSPERO: CRD42017082549). RESULTS: The systematic search revealed 172 papers, of which 88 duplicates were removed resulting in 84 papers to screen. Based on title, abstract and full text review, six articles were included for final analysis. There were nine patients in total with an average age of 41 (three females, five males, one unspecified), all with significant polytrauma, secondary to the mechanism of injury. A variety of stents were used between centres, with techniques showing a predominance to stenting of the left subclavian artery (77%, n = 7). The technical success rate was 82%, with two (18%) cases of type 1 endoleaks, of which one resolved spontaneously. CONCLUSIONS: Despite the encouraging results, this by no means provides for a firm conclusion given the small sample size. Patients should still be judiciously selected on a case-by-case basis when employing the chimney graft technique. Larger cohort studies are needed to establish these findings.

INTRODUCTION: Blunt traumatic thoracic aortic injury, the second leading cause of death from trauma, poses unique challenges in its management. However, there has not yet been a corresponding consolidated series of outcomes reported in Asia, which this systematic review aims to address. METHOD: This review was performed as per the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Searches were performed on MEDLINE, EMBASE, Google Scholar, and Cochrane Database for studies performed in Asia reporting the endovascular management of blunt traumatic thoracic aortic injury. Risk of bias was assessed using the Newcastle-Ottawa scale. Meta-analyses of pooled proportions were performed using the metaprop command in STATA. This review has been prospectively registered in PROSPERO (CRD42018083773). RESULTS: Sixteen retrospective cohort studies were included, reporting a total of 238 patients. The pooled Injury Severity Score was 32.5 (95%CI 27.8-37.1). The pooled mean time to operation from diagnosis was 39.2 hours (95%CI 24.6-53.8 hours), and operation time was 100 min (95%CI 63.5-136.5 min). The pooled rate of procedural conversion from endovascular repair to open surgery was 0.17% (95%CI 0-3.7%), and the proportion of left subclavian artery coverage was 55% (95%CI 37-72%). The pooled prevalence of intra-operative all-cause and aortic-related mortality was 0.72% (95%CI 0-4.9%) and 0.27% (95%CI 0-3.8%), respectively. The pooled prevalence of 30-day all-cause and aortic-related mortality was 2.2% (95%CI 0.16-5.6%) and 2.1% (95%CI 0-3.7%), respectively. In terms of 30-day complication, the pooled prevalence rates of type 1 endoleak, endograft complications, vascular access injury, strokes, and aortic re-rupture were 1.2%, 0.34%, 0.14%, 0.02%, and 0.01%, respectively. There were no cases of types II and III endoleak, and renal failure. CONCLUSION: Short- to mid-term results for thoracic endovascular aortic repair for blunt traumatic thoracic aortic injury in Asia are encouraging. However, there is a distinct disparity in reporting across Asia. We propose a prospective database for outcome reporting post thoracic endovascular aortic repair in this patient population, and ongoing follow up to assess long-term efficacy of this treatment strategy.

INTRODUCTION: The clinical significance of Type II endoleak remains contentious; the strategies used for its management have continued to expand. We systematically review the literature and comprehensively appraise the effectiveness of laparoscopic intervention in the management of this common complication. METHODS: A systematic search was performed in accordance to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines on MEDLINE, EMBASE and Cochrane Library for relevant articles reporting laparoscopic surgery of Type II endoleak post-endovascular aortic repair. RESULTS: Thirteen studies representing 40 patients were investigated. Mean age was 72.7 years, and proportion of males was 90.0%. All patients were American Society of Anesthesiologists grade II and above and underwent standard infrarenal endovascular aneurysm repair. The mean duration of operation was 130.2 min, with a mean blood loss across of 173.8 mL. The overall technical success rate was 90% (27/30). Two patients required reoperation within 24 h, with further lumbar ligations that were successful. One other patient required conversion to open surgery due to significant bleeding at the dorsal aorta. The perioperative and 30-day mortality rate was 2.5% (1/40). The mean length of hospital stay was 3.7 days (range 1 to 10 days). The mean length of follow-up was 36.7 months (range 3 to 103.2 months), where the rate of recurrence was 22.5% (9/40). CONCLUSIONS: Laparoscopic ligation of feeding vessels causing Type II endoleak is potentially an alternative treatment after failed standard endovascular embolization, particularly in select centres with necessary resources and capabilities.

In patients presenting with gunshot wounds, a high clinical suspicion of injury to vasculature and viscera remote from the projectile track is paramount. We present a case of a 17 year old male who sustained a gunshot wound to his abdomen and subsequently developed a right external iliac artery contusion requiring surgery as an indirect effect of the pressure wave from the bullet.

OBJECTIVES: An increasing number of patients are diagnosed with exertional rhabdomyolysis secondary to indoor spinning. We performed a systematic review to characterize the clinical features of this new clinical entity. METHODS: We conducted a thorough literature search on PubMed, Embase, Web of Science, Scopus, and The Cumulative Index to Nursing and Allied Health Literature (CINAHL). Articles published from inception to 23 June 2021 were considered. A two-stage article selection process was performed. Articles that reported clinical characteristics and outcomes in patients with spin-induced exertional rhabdomyolysis (SIER) were included. Quality assessment was performed using the Joanna Briggs Institute checklists. RESULTS: There were a total of 22 articles and 97 patients with SIER. Most patients were healthy females who had attended their first spinning session. The mean time to clinical presentation was 3.1 ± 1.5 days. The most common presenting symptoms were myalgia, dark urine, and muscle weakness in the thighs. Seven patients (7.2%) developed acute kidney injury, and two patients (2.1%) required temporary inpatient hemodialysis. Four patients (4.1%) developed thigh compartment syndrome and required fasciotomies. No long-term sequelae or mortality were observed. The mean length of stay was 5.6 ± 2.9 days. CONCLUSIONS: Healthcare professionals must have a high index of suspicion for SIER when a patient presents with myalgia, dark urine, or weakness after a recent episode of indoor spinning. Fitness center owners, spinning instructors, and participants should also be better educated about the clinical features and manifestations of SIER.

INTRODUCTION: Central venous occlusive disease (CVOD) is a complication that can occur in patients with end-stage renal disease who are receiving hemodialysis. When CVOD develops, patients often require multiple re-interventions to maintain their dialysis access. CVOD can be treated by various strategies such as balloon angioplasty, stenting, lower limb or extra-anatomical grafts, hybrid grafts or surgical bypasses such as right atrial (RA). In this systematic review, we aim to evaluate the indications, technical aspects, and outcomes after RA bypass grafting for the treatment of CVOD in hemodialysis patients. METHODS: A systematic and comprehensive literature search was conducted using various electronic databases. We included articles that reported described and reported outcomes of RA bypass grafting for the treatment of CVOD in hemodialysis patients. A narrative review of the indications and technical aspects of RA bypass grafting was performed. We also pooled and reported the primary patency, secondary patency, postoperative complications, and 30-day mortality of RA bypass grafting. RESULTS: A total of 21 studies with 55 patients who underwent RA bypass grafting were included in our systematic review. Follow-up period ranged from 0.5 to 84 months. The mean pooled primary patency and secondary patency of RA bypass grafting were 8.1 ± 4.9 and 21.7 ± 20.1 months, respectively. The incidence of early postoperative complications such as surgical site infection, bleeding, and access thrombosis was 0%, 4%, and 4%, respectively. The overall 30-day mortality was 4%. CONCLUSIONS: This systematic review summarizes the patient characteristics, technical features and outcomes of RA bypass grafting in the treatment of hemodialysis-related CVOD. RA bypass grafting may be a viable last-resort option when less invasive or conventional treatment options have been exhausted.

Aortic rupture in the presence of aneurysmal disease is well understood and extensively described in the literature. However, aortic rupture in a non-aneurysmal aorta is far less common. In the few reported cases, perforations are believed to result from a penetrating atheromatous ulcer of the aorta. We describe a rare case of non-aneurysmal aortic rupture in a 68-year-old man with Marfan syndrome and a history of proximal aortic surgery. The urgent need for hemorrhage control precluded any consideration of an endovascular repair.

The aetiology, incidence and management of type II endoleaks in standard infrarenal endovascular aortic aneurysm repair is well described. Far less data is available for thoracic stent grafting. We present a rare and interesting case of a type II endoleak post thoracic aortic stenting and highlight the aberrant anatomy that can cause this phenomenon in such cases.
RESUMEN
Carotid endarterectomy is a standard vascular surgical procedure performed worldwide and encompasses multiple risks including cerebral hyperperfusion syndrome, stroke, carotid dissection and aneurysmal formation, all of which are well documented in the literature. However, neovascular glaucoma manifesting post carotid endarterectomy, is extremely rare and can have disastrous consequences if left undiagnosed. In this article, we present one such case of neovascular glaucoma manifesting post carotid endarterectomy and review the available literature on this uncommon entity.
RESUMEN
We present a rare case of a patient with aortoiliac occlusive disease on the background of type A crossed renal ectopia, for whom open surgical intervention was required. Aortic exposure in patients with concomitant crossed renal ectopia can present technical challenges to the vascular surgeon. The knowledge of variations in the ectopic renal blood supply is of paramount importance when performing surgery to treat this condition and affects the choice of surgical exposure. We present and discuss the operative details of our patient and outline an approach to this subset of patients.
RESUMEN
PURPOSE: To present a single case that clearly demonstrates the progression through the whole spectrum of an acute aortic syndrome, from a solitary penetrating aortic ulcer (PAU) through to multiple PAUs with intra-mural haematoma (IMH) progression. The index images show that despite the clinical presentation of an acute type B aortic dissection, a classical dissection flap is never demonstrated in this patient and thus highlights the need for early input from vascular surgery for all potential acute aortic syndromes. CASE REPORT: We present the case of a 71-year-old lady who attended the emergency department with hypertension and inter-scapular chest pain. Upon investigation with computed tomography aortography (CTA), she was found to have a solitary PAU only with minimal IMH. She did not demonstrate any classical radiological signs of acute type B aortic dissection. She was admitted under a medical team and her chest pain abated with no treatment. The treating medical team adjusted her anti-hypertensive medication and discharged her home with an urgent vascular surgical outpatient appointment for further follow-up and surveillance. We acknowledge that a preferred approach would have been, at least admission and close blood pressure monitoring, with a repeat CTA the next day. Two days later, she represented with further chest pain and on repeat CTA was found to have multiple PAUs and progression of the small IMH. She was then admitted under vascular surgery and subsequently transferred to the parent tertiary referral vascular surgical unit. Despite aggressive anti-hypertensive management, she had persistent intractable chest pain and was treated with a single thoracic stent graft. Completion angiography demonstrated total resolution of the PAUs. CONCLUSION: This case along with index images demonstrates the whole spectrum of the acute aortic syndrome from a solitary PAU to multiple PAUs with IMH extension. Despite an eventual clinical picture of an acute type B aortic dissection, there was a notable absence of a classical dissection flap on any imaging. We recommend that all aortic pathologies should be at least discussed with and preferably managed by vascular surgeons. The absence of a classical dissection flap on imaging is not a contra-indication to emergent treatment with thoracic stent grafting and in select patients is actually the only therapy that will treat this pathology.

A literature review of peripheral primitive neuroectodermal tumours, illustrated with an index case report describing an 80-year-old woman who presented with a mass in the left popliteal fossa, is reported. An excision biopsy was performed, revealing a possible peripheral primitive neuroectodermal tumour as the primary pathology. Normally confined to the chest wall and axial soft tissues of children and young adults, reports of this tumour existing in other areas and in the elderly population are scarce.
Une analyse bibliographique des tumeurs neuroectodermiques primitives périphériques est présentée conjointement à un cas de référence décrivant une femme de 80 ans qui a consulté à cause d'une masse du creux poplité gauche. Une excision-biopsie a révélé la possibilité d'une tumeur neuroectrodermique primitive périphérique en pathologie primaire. Normalement, cette tumeur est confinée à la paroi thoracique et aux tissus mous axiaux des enfants et des jeunes adultes. Elle est rarement signalée dans d'autres foyers et au sein de la population âgée.
