Aneurysm III: Interprofessional Care

476
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...

Aneurysm I: Introduction

646
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 II: Clinical Manifestations and Diagnostic Studies

578
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 IV: Nursing Management

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

Anastomoses01:19

Anastomoses

3.7K
In human anatomy, anastomosis refers to a connection or opening between two things, particularly between blood vessels or other tubular structures. The term is derived from the Greek term 'anastomosis,' which means 'outlet' or 'opening.' This natural network of connections plays a critical role in the survival and functionality of the human body.
Anastomoses can be formed at arterial, venous, and lymphatic vessels.
Arterial Anastomosis: These occur between arteries. They...

Summary

Prepapillary vascular loops can lead to serious complications like macroaneurysm rupture and branch retinal artery occlusion. Intravitreal bevacizumab (IVB) treatment effectively resolved serous retinal detachment and improved vision in a patient with these conditions.

Area of Science:

  • Ophthalmology
  • Retinal Vascular Diseases

Background:

  • Prepapillary vascular loops are rare vascular anomalies.
  • Complications include macroaneurysm rupture and branch retinal artery occlusion (BRAO).
  • Management strategies for these complications are evolving.

Purpose of the Study:

  • To report a case of prepapillary vascular loops complicated by suspected macroaneurysm rupture and BRAO.
  • To evaluate the efficacy of intravitreal bevacizumab (IVB) in managing the resulting serous retinal detachment.

Main Methods:

  • Case presentation of a 62-year-old woman with decreased vision.
  • Diagnostic workup included fundus examination, optical coherence tomography, and indocyanine green angiography.
  • Treatment involved intravitreal bevacizumab (IVB) for persistent serous retinal detachment.

Main Results:

  • The patient presented with vision loss, retinal hemorrhage, and serous retinal detachment.
  • Indocyanine green angiography confirmed prepapillary vascular loops and suggested a macroaneurysm with possible BRAO.
  • Following IVB treatment, visual acuity improved from 0.6 to 1.0, with resolution of serous retinal detachment and an organized macroaneurysm.

Conclusions:

  • Prepapillary vascular loops pose a risk for sight-threatening complications.
  • Intravitreal bevacizumab (IVB) can be an effective treatment for associated serous retinal detachment.
  • Close monitoring of patients with prepapillary vascular loops is crucial for early detection and management of complications.
