Why Do Some Leg Wounds Take So Long to Heal? How Poor Blood Circulation Can Delay Wound Healing A Guide to Leg Ulcer Causes & Treatment in Pune Most stubborn leg wounds trace back to poor circulation, even though it's rarely the first thing that comes to mind. Skin needs a steady flow of oxygen and nutrients, delivered through blood. When that flow weakens, blood struggling to reach the legs or failing to drain back out properly, tissue repair falls behind. A wound that should close in a week ends up lingering for a month, sometimes longer. Venous insufficiency explains a lot of these cases. Vein valves weaken over the years, letting blood pool low in the legs instead of moving back up. Pressure builds where it shouldn't, and eventually skin gives way, usually near the ankles, into an ulcer that doesn't respond to typical wound care. Arterial insufficiency gets there differently. Arteries narrow, sometimes shut off completely, and oxygen-rich blood stops reaching feet and lower legs properly. Tissue starved this way turns fragile fast, and these ulcers tend to hurt more, heal slower too, compared to venous ones. Diabetes tends to make things worse across the board. Nerve damage means injuries go unnoticed longer, and healing capacity drops at the exact same time circulation's already struggling. Fixing the ulcer by itself rarely solves the real issue. Whatever's restricting circulation needs attention too, or the wound just comes back, sometimes worse than before. That's the whole point of proper vascular evaluation. An experienced interventional radiologist in Pune uses imaging to pinpoint what's actually behind the poor circulation, steering treatment toward the real cause instead of managing the wound alone.
