Insights

This study details rare abdominal aortic branch dissections in Japan, finding most patients were male, middle-aged smokers with hypertension. While many received conservative treatment, some required embolization or surgery, with a small number of in-hospital deaths.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Gastroenterology

Background:

  • Isolated dissections of abdominal aortic branches are rare, with limited data from small case series.
  • Understanding the clinical features, risk factors, and outcomes is crucial for patient management.

Purpose of the Study:

  • To describe the clinical characteristics of patients with isolated celiac, superior mesenteric, splenic, and hepatic artery dissections (ICAD, ISMAD, ISAD, IHAD).
  • To analyze treatment modalities and in-hospital outcomes for these rare vascular events.

Main Methods:

  • Retrospective analysis of a Japanese national inpatient database (July 2010 - March 2013).
  • Inclusion criteria: patients diagnosed with ICAD, ISMAD, ISAD, or IHAD.
  • Data extracted: demographics, risk factors (smoking, comorbidities), treatments (transcatheter arterial embolization (TAE), surgery), and outcomes (complications, death).

Main Results:

  • Identified 276 ICAD, 715 ISMAD, 23 ISAD, and 11 IHAD among 18.3 million inpatients.
  • Predominantly affected males (78-92%), mean age 54.7-56.8 years.
  • Common comorbidities included hypertension (48-65%); 35-65% were smokers.
  • Most patients managed conservatively; TAE and surgery were used in a minority.
  • 14 in-hospital deaths occurred across all groups.

Conclusions:

  • Isolated abdominal aortic branch dissections predominantly affect middle-aged males with vascular risk factors.
  • Conservative management is common, but interventions like TAE and surgery are sometimes necessary.
  • While rare, these conditions can lead to significant morbidity and mortality.

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Aneurysm I: Introduction

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests01:22

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Abdominal Aorta01:25

Abdominal Aorta

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...
