Summary
Percutaneous transluminal angioplasty and stenting (PTAS) via upper-extremity access successfully treated innominate artery stenosis (IAS) when transfemoral access was not feasible. These cases highlight effective distal embolic protection strategies for complex IAS interventions.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Cerebrovascular Disease
Background:
- Innominate artery stenosis (IAS) can lead to severe hypoperfusion and ischemic events.
- Percutaneous transluminal angioplasty and stenting (PTAS) is a treatment option for IAS.
- Limited reports exist on PTAS exclusively via an upper-extremity approach.

Peripheral Artery Disease III: Interprofessional Care
Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
Peripheral Artery Disease V: Postoperative Nursing Management
During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
