What is PTS? The \u201cpermanent damage\u201d after thrombosis explained simply <\/b><\/h2>\n<p><span style=\"font-weight: 400;\">To understand why your leg hurts, a comparison helps: Imagine your vein as a motorway on which blood flows back to the heart. A thrombosis was a serious accident that blocked all lanes. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Even when the debris (the clot) has been cleared, the motorway is often no longer the same:<\/span><\/p>\n<ul>\n<li><b>Scarred narrowings (obstruction):<\/b><span style=\"font-weight: 400;\"> The vein is narrowed, as if by a permanent construction site. Old scar tissue makes the vessel rigid and narrow.<\/span><\/li>\n<li><b>Damaged valves (reflux):<\/b><span style=\"font-weight: 400;\"> There are valves in the veins that, like locks, prevent the blood from pooling downward. Thrombosis has often destroyed these valves. The blood now flows back into the leg, following gravity. <\/span><\/li>\n<\/ul>\n<p><b>The result:<\/b><span style=\"font-weight: 400;\"> A <\/span><b>venous hypertension<\/b> develops<span style=\"font-weight: 400;\"> \u2013 chronic high pressure in the leg. This pressure forces fluid into your tissue, leading to swelling and pain.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><b>2. Why conventional examinations are often \u201cblind\u201d<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Many patients come to us and say, \u201cMy GP did an ultrasound and found nothing.\u201d This is not due to the doctor, but to the physical limitations of standard methods. <\/span><\/p>\n<h3><strong>External ultrasound (duplex)<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">Standard ultrasound looks from the outside through skin and tissue. It is like looking through a window from the street: you can see the fa\u00e7ade, but not the details in the hallway. Especially in the pelvic area, intestinal gas or bones often obscure the view of the decisive narrowings.   <\/span><\/p>\n<h3><strong>X-ray phlebography<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">Contrast agent is injected here. The problem: it is a two-dimensional shadow image.  A vein can look completely normal from the front, while, when viewed from the side, it is almost completely compressed by an overlying artery (the so-called &#8221; <\/span><b>May-Thurner syndrome<\/b><span style=\"font-weight: 400;\">).<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><strong>3. The revolution at VenaZiel\u00ae: Philips\u00ae IVUS \u2013 the \u201ceye\u201d inside the vein<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">At <\/span><b>VenaZiel\u00ae<\/b><span style=\"font-weight: 400;\">  begin where others must stop. We use the  <\/span><b>Philips\u00ae IVUS<\/b><span style=\"font-weight: 400;\">. This stands for  <\/span><b>I<\/b><span style=\"font-weight: 400;\">ntra<\/span><b>v<\/b><span style=\"font-weight: 400;\">ascular <\/span><b>u<\/b><span style=\"font-weight: 400;\">ltra<\/span><b>s<\/b><span style=\"font-weight: 400;\">ound.<\/span><\/p>\n<h3><strong>How does the view from the inside work?<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">Instead of scanning from the outside, we insert a tiny probe (smaller than a noodle) directly into the vein. At the tip is a high-tech sensor from our partner &#8221; <\/span><b>Philips\u00ae<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<ul>\n<li><b>360-degree view:<\/b><span style=\"font-weight: 400;\"> The probe provides live images from inside the vessel.<\/span><\/li>\n<li><b>No shadows:<\/b><span style=\"font-weight: 400;\"> We can see every scar, every narrowing, and every obstruction crystal-clear, without bones or gas interfering with the view.<\/span><\/li>\n<\/ul>\n<p><b>In scientific terms:<\/b><span style=\"font-weight: 400;\"> IVUS enables a morphological assessment of the vessel wall and the lumen in real time. It is the gold standard for precisely measuring the vein\u2019s \u201carea\u201d (cross-sectional area).<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><strong>4. When is IVUS at VenaZiel\u00ae useful for you? (Indications) <\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">We use this specialised diagnostic method whenever we suspect a mechanical cause for your symptoms.<\/span><\/p>\n<h3><strong>A. Suspected May-Thurner syndrome<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">The left pelvic vein is often compressed by an artery against the spine. Patients suffer from a persistently swollen left leg. Only IVUS can determine the extent of this compression with centimetre-level precision.  <\/span><\/p>\n<h3><strong>B. Deep venous insufficiency of the femoral vein<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">If your thigh vein (femoral vein) is \u201cleaky,\u201d we use IVUS to look one level higher into the pelvis. There is often congestion there. If we restore outflow in the pelvis, this often relieves the thigh vein so much that the symptoms disappear.  <\/span><\/p>\n<h3><strong>C. Post-thrombotic syndrome (PTS)<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">If your veins are scarred from an old thrombosis, IVUS shows us whether we can dilate these scars to normalise blood flow again.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><strong>5. Precision in treatment: placing the stent perfectly<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">If a vein is so severely narrowed that a <\/span><b>stent<\/b><span style=\"font-weight: 400;\"> (a small mesh support) has to be inserted, <\/span><b>Philips\u00ae IVUS<\/b><span style=\"font-weight: 400;\"> is our most important tool for your safety:<\/span><\/p>\n<ol>\n<li><b>The right size:<\/b><span style=\"font-weight: 400;\"> A stent must be neither too large nor too small. We measure your vessel to the exact millimeter.<\/span><\/li>\n<li><b>The perfect fit:<\/b><span style=\"font-weight: 400;\"> We immediately check whether the stent is in firm contact with the vessel wall everywhere. This is crucial to prevent the stent from becoming blocked again.<\/span><\/li>\n<li><b>The landing zone:<\/b><span style=\"font-weight: 400;\"> We determine exactly where healthy tissue begins and ends so that the stent is optimally anchored in the bloodstream.<\/span><\/li>\n<\/ol>\n<h2><\/h2>\n<h2><strong>6. Examination procedure: safe and painless<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">A procedure at <\/span><b>VenaZiel\u00ae<\/b><span style=\"font-weight: 400;\"> is minimally invasive. This means: we work through a tiny opening in the skin.<\/span><\/p>\n<ul>\n<li><b>Anaesthesia:<\/b><span style=\"font-weight: 400;\"> You will receive local anesthesia at the puncture site (e.g., in the hollow of the knee). If desired, twilight sedation is also possible.<\/span><\/li>\n<li><b>Sensation:<\/b><span style=\"font-weight: 400;\"> Because veins have no pain nerves on the inside, you will not feel the IVUS probe being advanced.<\/span><\/li>\n<li><b>Duration:<\/b><span style=\"font-weight: 400;\"> The examination usually takes only 30 to 60 minutes. After a short rest period, you can go home again.<\/span><\/li>\n<\/ul>\n<h2><\/h2>\n<h2><strong>7.
