Advanced Surgical Care for Artery, Vein & Complex Vascular Conditions
Open vascular surgery is a specialized surgical treatment used to repair, bypass, reconstruct, or remove diseased blood vessels when vascular conditions cannot be safely or effectively managed with medication or minimally invasive procedures alone. Patients may require open vascular surgery for conditions affecting the arteries, veins, aorta, carotid arteries, leg circulation, mesenteric arteries, or dialysis access. At Asan Medical Center in Seoul, South Korea, vascular surgery is supported by detailed diagnostic evaluation, advanced surgical planning, and multidisciplinary care for complex vascular disease. This approach helps international patients receive individualized treatment designed to restore blood flow, reduce serious vascular risks, and support long-term circulation health.
🔍 What Is Open Vascular Surgery?

Open vascular surgery refers to traditional surgical procedures performed through direct access to the affected blood vessel. The goal is to restore healthy circulation, prevent complications, remove blockages, repair weakened vessels, or create reliable vascular access when needed. This type of vascular surgery may be recommended for complex arterial blockages, abdominal aortic aneurysms, carotid artery disease, severe peripheral artery disease, venous disease, mesenteric artery problems, or vascular access complications in patients receiving hemodialysis.During open vascular surgery, the surgeon may remove plaque from an artery, bypass a blocked vessel, repair an aneurysm, revise a dialysis fistula, or reconstruct circulation using a graft or the patient’s own blood vessel when suitable. The procedure is performed under carefully monitored hospital conditions, with attention to blood flow, organ protection, wound healing, and post-operative recovery.
Open vascular surgery remains an important treatment option for selected patients, especially when vascular disease is advanced, anatomically complex, or unsuitable for endovascular repair.
🩺 Types of Open Vascular Surgery
- Carotid Endarterectomy – Removes plaque from the carotid artery in the neck to help improve blood flow to the brain and reduce stroke-related vascular risk in selected patients.
- Open Abdominal Aortic Aneurysm Repair – Repairs a weakened or enlarged section of the abdominal aorta using surgical reconstruction when open repair is considered appropriate.
- Peripheral Artery Bypass Surgery – Creates a new pathway for blood flow around blocked or narrowed arteries in the legs, helping improve circulation in patients with severe peripheral artery disease.
- Arteriovenous Fistula Creation or Revision – Creates, repairs, or revises vascular access for patients who require hemodialysis due to end-stage renal disease.
🩺 Who Is a Good Candidate?
Open vascular surgery may be suitable for patients with significant artery or vein disease that requires direct surgical repair. A vascular specialist determines candidacy after reviewing imaging, symptoms, medical history, and overall surgical risk. The best candidates are patients whose condition can benefit from improved blood flow, vessel repair, aneurysm treatment, or vascular access correction.
✔️ Individuals with leg pain while walking, rest pain, or poor wound healing due to reduced circulation
✔️ Patients with carotid artery narrowing who may require surgical plaque removal
✔️ Individuals with abdominal aortic aneurysm or iliac artery aneurysm requiring repair
✔️ Patients with complex vascular anatomy not suitable for simple catheter-based treatment
✔️ Individuals with mesenteric artery disease causing blood flow problems to the intestines
✔️ Patients with vascular access complications related to hemodialysis
✔️ Individuals with severe venous disease, swelling, skin changes, or venous ulcers
✔️ Patients who have completed vascular imaging and specialist evaluation
✔️ Adults with stable enough heart, kidney, lung, and general health for surgery
✔️ Patients who understand the recovery process and follow-up requirements

📝 Consultation & Preparation
Preparation for open vascular surgery begins with a detailed review of the patient’s vascular diagnosis, symptoms, imaging results, and previous treatments. International patients are usually asked to share recent medical records, medication lists, imaging reports, laboratory results, and specialist notes before the hospital evaluation. This helps the vascular surgery team understand the urgency, complexity, and safest treatment pathway.

✔️ Review of diagnosis, symptoms, medical history, and previous procedures
✔️ Evaluation of CT angiography, MR angiography, ultrasound, or vascular imaging when available
✔️ Non-invasive vascular testing when required to assess blood flow and vessel condition
✔️ Review of heart, kidney, lung, diabetes, and blood pressure status
✔️ Medication review, including blood thinners, antiplatelet therapy, diabetes medication, and supplements
✔️ Blood tests, cardiac assessment, anesthesia review, and infection screening if needed
✔️ Discussion of open surgery, endovascular options, or hybrid treatment when applicable
✔️ Explanation of surgical goals, hospital stay, possible risks, and expected recovery timeline
✔️ Planning for wound care, mobility support, follow-up imaging, and long-term vascular management
🩺 Recovery & Aftercare
Recovery after open vascular surgery depends on the type of operation, the patient’s condition before surgery, and the complexity of the vascular repair. Some patients require close monitoring in the hospital after surgery, especially when the procedure involves the aorta, carotid artery, major leg arteries, or dialysis access. The care team monitors circulation, wound healing, pain control, blood pressure, and overall recovery.
✔️ Hospital monitoring after surgery to assess circulation and general stability
✔️ Regular checks of pulses, limb temperature, skin color, and blood flow
✔️ Pain control and medication support during early recovery
✔️ Wound care instructions to reduce infection risk and support proper healing
✔️ Gradual walking and mobility guidance based on the surgical site
✔️ Avoiding heavy lifting, smoking, and strenuous activity during early healing
✔️ Blood thinner or antiplatelet management when prescribed by the specialist
✔️ Follow-up imaging or vascular ultrasound when needed to assess the repair
