Arterial Occlusive and Stenotic Diseases
Dr. Scallan treats conditions characterized by narrowing or blockage of arteries, restricting blood flow to vital organs and limbs.
- Critical Limb Ischemia (CLI): Represents the end-stage of PAD and requires urgent revascularization efforts to prevent amputation.
- Peripheral Artery Disease (PAD) / Peripheral Vascular Disease (PVD): Often caused by atherosclerosis, significantly impacting mobility and limb viability if untreated.
Aortic and Other Arterial Aneurysmal Diseases
Dr. Scallan treats conditions involving abnormal dilation or bulging of arterial walls, primarily the aorta, posing a risk of rupture.
- Aortic Dissection: A serious condition in which the inner layer of the aorta tears, causing blood to flow between the layers of the aortic wall, forcing the layers apart.
- Abdominal Aortic Aneurysm (AAA): Often asymptomatic and detected incidentally; screening is recommended for at-risk individuals (e.g., older male smokers).
- Peripheral Artery Aneurysms (e.g., Popliteal, Femoral): Repair is often recommended to prevent limb-threatening complications.
This list is not exhaustive. For a comprehensive evaluation of your vascular health, a consultation with Dr. Oonagh Scallan is necessary.
- Peripheral Artery Disease (PAD) Management - Surgical & Endovascular: Minimally invasive endovascular procedures such as angioplasty, stenting, and atherectomy for PAD.
- Spider Vein Treatment (Sclerotherapy): Performed in an outpatient clinic setting.
- Non-Invasive Vascular Laboratory Interpretation (e.g., Duplex Ultrasound): Utilizing vascular lab findings to guide treatment decisions for arterial and venous disorders.
- Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE) Management - Select Interventions: Interventional treatments for extensive DVT or massive PE, such as catheter-directed thrombolysis or thrombectomy (often in collaboration with interventional radiology).
- Post-operative Vascular Care and Surveillance: Managing post-procedure care, including wound healing and medication adjustments.
