SVG Full Form In Medical In English
In the medical field, SVG stands for Saphenous Vein Graft. It is a surgical technique commonly used in Coronary Artery Bypass Grafting (CABG) to treat patients suffering from severe coronary artery disease (CAD). CAD occurs when the coronary arteries that supply blood to the heart muscle become narrowed or blocked due to the buildup of fatty deposits, leading to chest pain, shortness of breath, or even heart attacks. A Saphenous Vein Graft involves removing a section of the great saphenous vein, which is a long vein running along the inside of the leg, and using it to create a new pathway for blood to flow to the heart. The harvested vein is attached above and below the blocked area of the coronary artery, allowing blood to bypass the obstruction and reach the heart muscle efficiently.
The SVG procedure is preferred because the saphenous vein is easily accessible and long enough to create multiple grafts if needed. It has been a standard technique for several decades and continues to be widely practiced. However, compared to arterial grafts (like the internal mammary artery), SVGs are more prone to blockages over time due to the development of atherosclerosis within the graft. Despite this limitation, Saphenous Vein Grafts remain an essential part of cardiac surgery. They significantly improve blood flow, relieve symptoms like angina (chest pain), enhance the patient’s quality of life, and reduce the risk of life-threatening cardiac events.

सैफेनस वेन ग्राफ्ट एक सर्जिकल प्रक्रिया है, जिसका उपयोग मुख्य रूप से कोरोनरी आर्टरी बाईपास ग्राफ्टिंग (CABG) में किया जाता है। यह प्रक्रिया उन मरीजों के लिए की जाती है जिनकी दिल की धमनियाँ (कोरोनरी आर्टरीज़) संकरी या ब्लॉक हो जाती हैं, जिससे दिल को पर्याप्त मात्रा में रक्त और ऑक्सीजन नहीं मिल पाती।इस प्रक्रिया में डॉक्टर मरीज की टांग की अंदरूनी तरफ से एक लंबी नस जिसे ग्रेट सैफेनस वेन कहते हैं, निकालते हैं। फिर इस नस के टुकड़े को दिल की ब्लॉक धमनियों के ऊपर और नीचे जोड़ा जाता है ताकि रक्त एक नया रास्ता बनाकर ब्लॉकेज को बायपास कर सके और दिल तक पहुँच सके।
सैफेनस वेन ग्राफ्ट का उपयोग इसलिए किया जाता है क्योंकि यह नस शरीर में आसानी से उपलब्ध होती है और इसकी लंबाई पर्याप्त होती है जिससे कई ग्राफ्ट तैयार किए जा सकते हैं। हालांकि समय के साथ इसमें ब्लॉकेज या एथेरोस्क्लेरोसिस (धमनियों में चर्बी जमना) होने की संभावना रहती है।फिर भी, SVG दिल की बीमारियों के इलाज में एक महत्वपूर्ण भूमिका निभाता है। यह प्रक्रिया हृदय को पर्याप्त रक्त पहुंचाने, छाती में दर्द (एंजाइना) को कम करने और मरीज के जीवन की गुणवत्ता को बेहतर बनाने में सहायक होती है।

Frequently Asked Questions
What is the full form of SVG in medical terms?
SVG stands for Saphenous Vein Graft.
What is a Saphenous Vein Graft used for?
It is used in Coronary Artery Bypass Grafting (CABG) to bypass blocked coronary arteries and restore blood flow to the heart.
Where is the saphenous vein located in the body?
The saphenous vein is a long vein located in the inner side of the leg, extending from the ankle to the groin.
Why is the saphenous vein chosen for grafting?
It is long, easily accessible, and generally suitable for creating one or more grafts during heart bypass surgery.
Are there any risks or complications with SVG?
Yes, over time SVGs can become narrowed or blocked due to atherosclerosis, leading to reduced effectiveness.
How long does a saphenous vein graft last?
SVGs typically last around 5 to 10 years, though longevity can vary based on the patient’s health and lifestyle.
What are the alternatives to SVG in bypass surgery?
Arterial grafts, such as the internal mammary artery or radial artery, are commonly used alternatives with longer-lasting results.
SVG surgery considered safe?
Yes, CABG using SVG is a standard and generally safe procedure, though it carries risks like any major surgery.
Can SVG be done more than once?
Yes, redo bypass surgeries can be performed, but they are more complex and depend on the patient’s overall condition.
Conclusion
In the medical field, SVG (Saphenous Vein Graft) plays a vital role in coronary artery bypass grafting (CABG), offering a reliable solution to restore blood flow in patients with blocked coronary arteries. By using a vein from the leg, surgeons can create a new pathway for blood to reach the heart muscle, reducing the risk of heart attacks and improving overall heart function. Despite the possibility of long-term complications, SVG remains a widely used and effective technique in cardiac surgery, contributing significantly to the management of coronary artery disease and enhancing patients’ quality of life.
