Digital subtraction angiography in the diagnosis of retinal vascular disease
Insights
Digital subtraction angiography offers a safe and affordable alternative for diagnosing systemic vascular disease when conventional methods are too risky. This technique proved effective in managing various retinal vascular conditions in five patients.
Area of Science:
- Vascular Medicine
- Diagnostic Imaging
- Ophthalmology
Background:
- Conventional carotid angiography poses risks for certain patients.
- Systemic vascular disease can manifest with retinal vascular conditions.
- Need for safer, cost-effective diagnostic tools in vascular investigation.
Observation:
- Digital subtraction angiography (DSA) was employed in five patients with diverse retinal vascular issues.
- Patient 1: 55-year-old female with right internal carotid artery occlusion.
- Patient 2: 63-year-old male with bilateral internal carotid artery occlusions.
- Patient 3: 72-year-old male with left subclavian artery stem occlusion and innominate artery irregularity.
- Patient 4: 77-year-old male with optic nerve neovascularization and multi-arterial stenosis.
- Patient 5: 74-year-old male with recurrent left internal carotid artery stenosis.
Findings:
- DSA successfully identified the vascular abnormalities in all five cases.
- The technique aided in establishing accurate diagnoses for complex vascular conditions.
- DSA provided crucial information for guiding treatment strategies.
Implications:
- Digital subtraction angiography is a valuable, safe, and economical diagnostic method for systemic vascular disease.
- It is particularly useful for patients at high risk with conventional angiography.
- The findings support the broader application of DSA in managing retinal and systemic vascular pathologies.
Abstract:
Digital subtraction angiography is a safe, inexpensive method of investigating systemic vascular disease in patients for whom conventional carotid angiography is too risky. We used this technique in five patients with a variety of retinal vascular conditions--a 55-year-old woman with occlusion of the right internal carotid artery, a 63-year-old man with bilateral occlusion of the internal carotid arteries, a 72-year-old man with occlusion of the stem of the left subclavian artery and an irregularity of the proximal portion of the innominate artery, a 77-year-old man with optic nerve head neovascularization and stenosis of the left internal and external and right internal carotid arteries, and a 74-year-old man with recurrent stenosis of the left internal carotid artery. In all five cases, digital subtraction angiography was helpful in determining the diagnosis and course of treatment.
