Acute aortic dissection mimicking acute abdomen in a 14-year-old boy

Comprehensive management of type A acute aortic dissection in the paediatric population with ACTA 2 mutation: case reports and literature review of paediatric aortic dissection

Acute aortic dissection in the paediatric population is rare but lethal. We present two paediatric cases of type A acute aortic dissection that required emergent procedures and were later found to have genetic mutations. High index of suspicion, early clinical diagnosis, prompt treatment, the advantageous collaboration between the paediatric team and aortic surgeons, and familial genetic testing are paramount to achieve a good outcome.

Emergency vascular surgical care in populations with unique physiologic characteristics: Pediatric, pregnant, and frail populations

Vascular surgical emergencies are common in vascular surgical care and require complex decision making and multidisciplinary care. They are especially challenging when they occur in patients with unique physiological characteristics, such as pediatric, pregnant, and frail patients. Among the pediatric and pregnant population, vascular emergencies are rare. This rarity challenges accurate and timely diagnosis of the vascular emergency. This landscape review summarizes these three unique populations' epidemiology and emergency vascular considerations. Understanding the epidemiology is the foundation for accurate diagnosis and subsequent management. Considering each population's unique characteristics is crucial to the emergent vascular surgical interventions decision making. Collaborative and multidisciplinary care is vital in gaining expertise in managing these special populations and achieving optimal patient outcomes.

The characteristics of thoracic aortic dissection in autopsy-diagnosed individuals: An autopsy study

Thoracic aortic dissection (TAD) is the most common cause of sudden cardiac death associated with aortic diseases. The age of TAD victims in forensic studies is significantly younger than hospitalized patients with TAD, while only a few studies have been conducted on autopsy-diagnosed TAD deceased. A retrospective study was conducted at the Medicolegal Center of Sun Yat-sen University from 1999 to 2019 to address the characteristics of TAD victims. A total of 200 deceased from spontaneous rupture of TAD were assessed, with 165 (82.5%) males and 175 (87.5%) Stanford type A deceased. Our main results showed that compared with patients with TAD diagnosed during their lifetime, individuals diagnosed with TAD until an autopsy showed an earlier onset (43.80 years old) and less accompanied hypertension (<50%). Sudden death was the initial symptom of 32 decedents. Instead of chest/back pain (40 decedents), abdominal pain (59 decedents) was the most common initial symptom, and 42 decedents presented with no accompanying pain. A higher proportion of abdominal pain and the painless symptom was associated with a higher risk of misdiagnosis. Women showed a more atypical clinical presentation and rapid progression than men. Younger decedents showed more pronounced left heart changes. The present study implicated the TAD individuals diagnosed until an autopsy as a particular entity, indicating the urgent need for further investigation on early diagnosis and pathogenesis of patients with TAD with atypical pain and painless or with younger age to reduce the burden of TAD-related sudden death.

Aortic Rupture by an Acute Dissection of the Thoracoabdominal Aorta in a 12-Year-Old Boy

Aortic dissection is exceptional in children. When they are affected, many clinical conditions as Marfan syndrome or Ehlers-Danlos syndrome are usually involved, but up to 22% have no associated background. Its high morbidity and low incidence in this age group require a high level of suspicion in children without predisposing factors when the presentation is atypical, to avoid the severe consequences of the delay of their diagnosis. In this article we describe the dissection and aortic rupture in a 12-year-old child without relevant medical history, and the open repair that was performed as treatment.

The risk of misdiagnosis in acute thoracic aortic dissection: a review of current guidelines

Acute aortic syndrome and in particular aortic dissection (AAD) persists as a cause of significant morbidity and mortality despite improvements in surgical management. This clinical review aims to explore the risks of misdiagnosis, outcomes associated with misdiagnosis and evaluate current diagnostic methods for reducing its incidence.Due to the nature of the pathology, misdiagnosing the condition and delaying management can dramatically worsen patient outcomes. Several diagnostic challenges exist, including low prevalence, rapidly propagating pathology, non-discrete symptomatology, non-specific signs, analogy with other acute conditions and lack of management infrastructure. A similarity to acute coronary syndromes is a specific concern and risks patient maltreatment. AAD with malperfusion syndromes are both a cause of misdiagnosis and marker of disease complication, requiring specifically tailored management plans from the emergency setting.Despite improvements in diagnostic measures, including imaging modalities and biomarkers, misdiagnosis of AAD remains commonplace and current guidelines are relatively limited in preventing its occurrence. This paper recommends the early use of AAD risk scoring, focused echocardiography and most importantly, fast-tracking patients to cross-sectional imaging where the suspicion of AAD is high. This has the potential to improve the diagnostic process for AAD and limit the risk of misdiagnosis. However, our understanding remains limited by the lack of large patient datasets and an adequately audited processes of emergency department practice.

A case report of unexpected sudden cardiac death due to aortic rupture following laparoscopic appendectomy

INTRODUCTION

Aortic dissection is a very rare but life-threatening condition associated with a high mortality. Unexpected sudden cardiac death due to aortic rupture following laparoscopic appendectomy is very rare and may be difficult to diagnose. However, early diagnosis of aortic dissection is essential for the timely treatment and outcome of aortic dissection.

CASE PRESENTATION

A 50-year-old man underwent a laparoscopic appendectomy. Postoperatively, the patient complained of dyspnea and chest pain. In 25 minutes after arrival in the postanesthesia care unit (PACU), the patient was in asystole. Then, he underwent cardiopulmonary resuscitation (CPR) according to advanced cardiac life support (ACLS) protocol using 1 mg of epinephrine, one 200J DC shock for ventricular fibrillation (V-fib). After that, his noninvasive blood pressure (NIBP) was 80/40 mm Hg, pulse rate (PR) was 140 beats/min, and peripheral oxygen saturation (SpO2) was 84%. His electrocardiogram (ECG) finding was atrial fibrillation (A-fib). After 20 minutes, the patient developed asystole rhythm again and CPR was restarted. He remained severely hypotensive despite vasopressors and died after 5 hours CPR. A forensic autopsy was performed postmoterm and thoracic and abdominal aortic dissection along the root of ascending aorta was present and massive hematoma within right and left thorax was present.

CONCLUSION

Acute aortic disease can be difficult to recognize; therefore, diagnosis is sometimes delayed or missed. It is important to recognize the atypical symptoms of aortic dissection and maintain a broad differential diagnosis if patients complained of abdominal pain.
