Insights

Conservative therapy for splenic injuries preserves immune function. Two pediatric cases of splenic artery pseudoaneurysm resolved spontaneously, highlighting a potential non-invasive outcome for traumatic splenic injuries.

Area of Science:

  • Pediatric Traumatology
  • Vascular Surgery
  • Radiology

Background:

  • Conservative management of splenic injuries is preferred for preserving immune function and avoiding surgical complications.
  • Increased use of imaging has led to more frequent detection of splenic artery pseudoaneurysms during follow-up.
  • Splenic artery pseudoaneurysms can occur as a complication of splenic trauma, even with non-operative treatment.

Observation:

  • Two pediatric patients with post-traumatic splenic artery pseudoaneurysms were identified.
  • One pseudoaneurysm thrombosed during diagnostic angiography.
  • The second pseudoaneurysm thrombosed spontaneously during follow-up imaging.

Findings:

  • Spontaneous thrombosis is a possible resolution pathway for splenic artery pseudoaneurysms in children.
  • Diagnostic angiography may coincide with or trigger pseudoaneurysm thrombosis.
  • Non-operative management of splenic injuries can lead to pseudoaneurysm formation but also spontaneous resolution.

Implications:

  • These cases suggest that conservative management of splenic artery pseudoaneurysms in children may be successful.
  • Further investigation into the natural history and management of splenic pseudoaneurysms is warranted.
  • Preservation of splenic function can be achieved through non-operative strategies, including watchful waiting for pseudoaneurysm resolution.

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...

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Esophageal Perforation-II: Clinical Manifestations and Management

Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.
