No inheritance, no bad luck passed to your children — just one of those delightful anatomical quirks that affects 20-25% of people and gets diagnosed in approximately nobody until something irreversible has already happened. Why no swelling? Because your body, being rather clever, built bypass veins from birth. Collaterals. A shadow network that keeps things just functional enough to fool every doctor you will ever visit. Light activity? Fine. Decades of desk work, prolonged standing, physical labour? The system starts cracking. Pressure builds. Walls stretch. Pain arrives in the left flank, left lower back, left leg, left testicle — and six different specialists treat six different “diseases” that are actually one plumbing problem nobody thought to check. After puberty the compensation collapses further. Varicocele forms — not a disease in itself but a pressure valve for blood that has nowhere to go. Valves fail. Surgeons remove the varicocele, the great saphenous vein, every available collateral — not realising these were the lifeboats. The tailored suit, as one urologist memorably said, cannot be re-sewn once ruined. Correct observation. Old-school vascular surgeons still demand 90% compression plus thrombosis plus visible swelling before they’ll consider stenting. Waiting for all three in a nonthrombotic patient is like refusing to treat angina until the heart attack arrives. Modern dedicated venous stents, sized and placed under IVUS guidance, last a lifetime. In the nonthrombotic group — no prior DVT, intact vein walls — stent thrombosis risk is negligible. No lifelong anticoagulation. No repeat procedures. Just a restored highway where there was a permanent roadblock. Fix it deep first. Before the suit is ruined.
