Vascular Surgery

Introduction

Vascular surgery is a medical subspecialty covering all conditions affecting blood vessels, arteries and veins. Healthcare providers use a broad spectrum of procedures to treat vascular diseases affecting blood circulation, which can result in devastating complications, including stroke, myocardial infarction, or limb amputations. Vascular surgery, including carotid endarterectomy, bypass surgery, and other vascular procedures, plays an important role in the treatment of morbidity of atherosclerosis, aneurysms and peripheral artery disease (PAD).

Experienced surgeons, advanced technology, and rational medical choices have contributed to the successful development of vascular surgeries in India. This article will comprehensively analyze the different vascular surgeries, including carotid endarterectomy and bypass surgeries, their advantages, risks, prices, and recovery period.

What is Vascular Surgery?

If any symptom is associated with diseases of the vessels of blood, it would be treated by vascular surgery, such as the treatment of arteries and the treatment of veins. This specialty corrects diseases affecting blood vascularization. Vascular diseases may cause extreme complications, including heart disease, stroke and organ damage.

The following are some of the commonly managed conditions by vascular surgery:

• Atherosclerosis (plaque buildup in the arteries)
• Peripheral artery disease (PAD)
• Carotid artery disease (leading to stroke)
• Aortic aneurysms
• Varicose veins
• Venous insufficiency

Vascular surgeons employ both minimally invasive (e.g., endovascular procedures) and conventional open approaches in treating [these] conditions.

Why is Vascular Surgery Performed?

Vascular surgery is carried out for the treatment of diseases that affect blood circulation, which can result in a whole spectrum of complications, including, but not limited to, organ failure, stroke and death. Vascular surgery is often necessary when other treatments, such as medication or lifestyle changes, are not effective in managing the disease.

Some common reasons for vascular surgery include:

• Blocked or Narrowed Arteries: Arterial narrowing resulting from conditions such as atherosclerosis can cause the arteries to constrict, with a consequence of diminished blood flow, resulting in significant and serious complications, such as stroke, myocardial infarction, etc.
• Aneurysms: An abnormality in the wall of an artery may result in a possible apocalyptical rupture. Surgery is performed to repair or remove the aneurysm.
• Varicose Veins: The swollen and twisted nature of veins may lead to pain and complications. Vascular surgery can be used to reduce symptoms and promote blood circulation.
• Peripheral Artery Disease (PAD): PAD is a condition of inadequate blood flow of the extremities, with subsequent possible gangrene unless properly treated. Surgery is carried out to enhance blood circulation and prevent further damage.

Types of Vascular Surgeries

There are so many types of vascular surgeries used to treat various vascular diseases. Some of the most common procedures include:

• Carotid Endarterectomy: This technique is applied to treat carotid artery disease, an entity in which plaque accumulates in the carotid arteries and thereby raises the risk of stroke. In this surgery, the surgeon removes the plaque to restore normal blood flow to the brain.
• Bypass Surgery: That is, in bypass surgery, a surgeon constructs a bypass of a constricted or occluded artery. The most frequent surgical procedure is coronary artery bypass grafting (CABG), but in other arteries than the coronary arteries (e.g., femoral artery, tibial artery, cervical artery), bypass surgeries could be performed.
• Endovascular Procedures: These are small incision procedures in which a catheter is guided into a blood vessel to remove a stenosis or repair a damaged blood vessel. This method is commonly applied in the treatment of aortic aneurysms or peripheral artery disease.
• Aneurysm Repair: Assuming an aneurysm (an abnormal fusiform enlargement of the artery wall) is available, surgery can be performed to repair or excise the aneurysm to prevent recanalization. This may be achieved by traditional open surgery or by less invasive approaches.
• Varicose Vein Surgery: Operative interventions for varicose veins are the surgery-based venoplasty of vein stripping (excision of the varicose vein), endovenous laser therapy (ELT) or enclosure via sclerotherapy (injection of a local substance to occlude the vein).

Procedure Steps for Vascular Surgery

Procedures in vascular surgery can differ depending on the type of surgery that is being considered. However, the general procedure typically involves the following:

1. Pre-Operative Evaluation: At the time of surgery, the patient undergoes a battery of preregistration tests, such as blood tests, imaging (ultrasound and CT scan), physical examination of the affected area, preoperative evaluation of disease severity, and surgical planning.
2. Anesthesia: Vascular surgeries are commonly performed under generalized anesthesia, in which the patient is anesthetized and free from pain during surgery. In some cases, local anesthesia may be used.
3. Incision: If other surgery is required, then an incision is made in the vicinity of the surgical site. In laparoscopic surgery, larger cuts (incisions) are necessary to reach the blood vessels. For endovascular surgery, tiny cuts are created to place a catheter.
4. Treatment: During carotid endarterectomy, the surgeon adducts plaque within the carotid artery. During bypass surgery, the surgeon performs a graft from a vein or a synthetic material to destroy the blocked artery. During endovascular procedures, the operator introduces a catheter to address the stenosis or the aneurysm.
5. Post-Operative Care: Postoperatively, patients are cared for in the hospital for the development of complications, including bleeding or infection. Recovery times depend on the surgery, but patients are usually hospitalized for a few days to a week.

Benefits of Vascular Surgery

Vascular surgery has a wide range of advantages for patients with vascular diseases, such as:

• Improved Blood Flow: Vascular surgeries restore the normal blood flow to vital organs, including the ain, heart, and limbs, thereby avoiding further complications.
• For patients with carotid artery disease or coronary artery disease, surgical treatment can decrease the risk of both stroke and myocardial infarction.
• Pain Relief: Vascular surgery can improve the symptomatology of pain and discomfort resulting from diseases such as peripheral artery disease or varicose veins.
• Preventing Amputations: Blood flow to the limb(s) can be improved with bypass surgery or endovascular procedures to avoid amputation in cases of severe peripheral artery disease.

Cost of Vascular Surgery

• USA: $20,000-$100,000. 
• UK: $15,000 – $60,000 
• India: $1,500 – $12,000 
• Thailand: $8,000 – $20,000 
• Mexico: $5,000 – $15,000 USD

India offers highly skilled surgeons and advanced medical facilities at a fraction of the cost found in Western countries, making it a popular destination for medical tourism.

Best Hospitals in India for Vascular Surgery

India has many highly respected hospitals that are specifically focused on vascular surgery. Among the leading hospitals for vascular surgery in India are:

• Medanta—The Medicity, Gurgaon: Medanta is internationally renowned for its specialization in cardiovascular and vascular surgery and provides the best treatment facility for a variety of vascular diseases.
• Fortis Memorial Research Institute, Gurgaon: Provides a full range of vascular care, from traditional open surgery to minimally invasive approaches.
• Apollo Hospitals, Chennai: A center of excellence in vascular surgery, with outstanding care for arterial and venous disease in India.

Risks and Complications

Like any major surgery, vascular surgery is associated with risk and complications, such as:

• Infection: Infection at the site of incision or within the vascular system is a risk.
• Bleeding: Patients may experience bleeding during or after the surgery.
• Blood Clots: Postoperatively, blood clots may occur, which may result in other complications such as stroke or pulmonary embolism.
• Graft Failure: The graft may fail in the context of bypass surgery, thus inducing a recurrence of the condition obstructing the vessel.
• Organ Injury: Surgery can cause damage to adjacent organs/tissues in very rare cases.

Recovery After Vascular Surgery

After vascular surgery, the process of rehabilitation differs based on the operation but typically includes:

• Hospital Stay: Patients generally remain in the hospital for 3-7 days after surgery, according to the complexity of surgery.
• Follow-Up Appointments: Follow-up visits are mandatory to assess healing as well as to check for adverse events.
• Physical Rehabilitation: Physical therapy may be needed to restore maximal mobility for some patients, particularly after bypass surgery.
• Medications: Pain medication and blood thinner may be prescribed to block thrombosis.
