One needs to be aware of this crucial fact since surgery is one of the major risk factors in case of DVT, a condition wherein blood clot forms in the veins within the muscles. Legs are the mostly commonly affected body part. Blood clot could become detrimental to health in case it ruptures open within one of such deep veins and reach inside the lung blocking blood supply. This form of obstruction is known as pulmonary embolism and would prevent oxygen reaching the blood.

Surgery and DVT Risk

Blood clot formation could occur due to blood supply slowing down, some injury to the interiors of the vein or blood clotting too soon, all of which could occur during or post-surgical procedure.

Minor, brief operative procedures generally do not lead to DVT, however, lengthy operations, particularly those which need the patient to be anesthetized (general) and those procedures done on the lower body areas place a person at risk.

For instance, DVT is prevalently the reason behind urgent re-admission following joint replacement operation.

One needs to be aware of the following vital truths about DVT prior to undergoing surgery.

• Operative procedures conducted under the influence of general anaesthesia that involve keeping the person stationary on the surgery table for extended times might lead to the veins relaxing which allow blood pooling. Due to blood flow slowing down, there is greater likelihood of clot formation.
• Bone surgery (like the knee, hip) could emit matter (protein, fat types) inside the blood which spur clot formation.
• Harm to vein wall at the time of an operation or they could face compression due to inflamed tissues which surround the veins. These occurrences could promote blood clot development.
• Major operative procedures necessitating immobility or subsequent bed rest are far perilous since such inactiveness could slacken blood supply.
• DVT risk during or post-surgery could additionally augment because of factors not related to surgical procedure like old age, being obese or overweight, those who smoke, intake of estrogen-containing drugs, cancer patients or those with a past of blood clot formations.

How could physicians lower risk of deep vein thrombosis symptoms arising?

Physicians are well-aware of DVT as a likely risk factor of surgery and are ably prepped to tackle any complications. The physician must be informed about a personal or family history of blood clots who could then take the following pre-emptive measures to shield the person from developing deep vein thrombosis symptoms.

• Drugs
  
  Anticoagulant medicines or blood thinners, before or post-surgery could be taken by the patient subsequent to surgery till DVT risk has subsided. Such medications could be administered via intravenous route or orally. It is now general practice to offer a patient at elevated risk or undergoing a high risk surgery such drugs before, at the time of and following operative procedure.
• Pneumatic compression stockings
  
  These stockings aid in maintaining optimal blood supply in the lower extremities. Such specially created stockings are inflatable with an air-pump after which the air would move via them and squeeze blood backwards in the direction of the heart when the patient is in supine position.
• Exercising

  Patients are recommended getting up and walking as early as doable post-surgery. While bed-ridden, the feet could be pumped upwards and downwards and muscles (claves and thighs) could be flexed to avert blood clot formation

Researchers are creating an automated plastic stripe which can evaluate the risk of developing deep vein thrombosis amongst lengthy haul air flight travelers.

The novel system would need placement of a single droplet of blood that would be examined by a bio-chip searching for blood clotting indicators or markers which point towards a high risk of deep vein thrombosis.

The disposable cartridge plate is a portable system that could be promising, life-saving choice for those people at risk of developing clotting disorders, inclusive of expectant mothers, stroke sufferers, those smoking or overweight.

At the outset, it is anticipated that doctors would interpret the results via a small manual scanner.

However analogous to how diabetes is checked with the use of personal screens for reading insulin levels, it is anticipated that those people at risk of developing deep vein thrombosis would sooner or later be able to do a self-check of their blood clotting levels.

The DVT analytical test would eventually become accessible in hospital settings and general practitioner’s operations wherein instant results would be obtainable thus curbing the earlier waiting for several days to get the laboratory results.

DVT occurs due to a person being immobile for lengthy time spans. This is the case for passengers during air travel which leads to the development of a blood clot in the deep veins of the legs. In case the blood clot is not treated it could have perilous consequences.

In case the developed blood clot charts its course and manages to reach the lungs, a pulmonary embolism could develop that could lead to lung collapse and cardiac failure.

Investigators hailing from 8 countries in Europe are crafting the technology for the DVT system and several other intelligent plastics for monitoring body functioning. For instance, sensor wrist bands for measurement of electrical smog to caveat heart patients with pacemakers implanted of life-menacing exposure.

Around 10 principal study institutions and high-tech companies in Europe are presently at work endeavoring to engineer the DVT analytical system.

Engineering of the sensor wrist band is being done at the German research institute Fraunhofer IZM. Prof. Karlheinz Block heading the Polytronic Systems at the institute states that the sensor wrist band illustrates the potential which lay inside the plastic electronics built on the foils.

The sensor wristband could provide long term examination of varied significant body functioning for elderly patients and sports persons.

The wristband resembles a plastic wrist watch; however the dial is replaced by a lighted electro-luminescent display which shows for instance, the true body temperature during any instant of the day.

It additionally helps in detecting dampness on the skin that might be an indicator of the patient or sports person being dehydrated.

In patients fitted with pacemakers, the sensor wrist band could additionally warn of likely danger, pointing towards the electro-magnetic field strength located closely.

• Preventing blood clots from growing bigger in size.
• Preventing the blood clot from reaching the lungs which could lead to pulmonary embolism.
• Preventing postthrombotic syndrome – a disorder leading to inflammation of the inflicted leg.
• Preventing blood clots from recurring.

Preliminary Line of Treatment

In case signs & symptoms of deep vein thrombosis have been identified, then testing would commence instantaneously for ascertaining if one had a blood clot in the leg. Alternatively, in case blood clot has been diagnosed in the lung – a condition known as pulmonary embolism, then the physician would carry out tests for deep vein thrombosis.

Following diagnosis of deep vein thrombosis, treatment commences right away for reducing the chances of the blood clot growing or a portion of the clot could loosen out and make its way to the lungs leading to pulmonary embolism. Treating such an individual early on would lower chances of postthrombotic syndrome.

Anticoagulant drugs namely warfarin (like Coumadin) and heparin are employed for treating DVT. Heparin is administered via intravenous route or as a shot and has instant action. Warfarin is administered orally and could take a number of days for becoming effectual. Frequently, the duo medications are commenced together, after which heparin is stopped subsequent to warfarin becoming effectual. Several individuals could be advised long-term use of LMWH (low-molecular-weight heparin) rather than warfarin.

In case blood clot has developed in the proximal leg vein (upper part) then warfarin intake would be recommended for 3-6 months or more. Based on the individual risk factors and conclusion of indicated time period of intake, continuing lesser warfarin (like Coumadin) dosages on an on-going basis would be medically advised for preventing DVT from relapsing.

Duo heparin forms are obtainable for treating DVT, namely, unfractioned heparin or UH which is administered in the hospital facility and LMWH could be self-injected in the convenience of one’s home.  LMWH heparin generally does not need intervallic blood analysis for monitoring its outcomes, though each of these anticoagulant medications have equal efficacy.

Classically, in case blood clot has developed in calf region (distal leg vein) then anticoagulants would be advised for three to six months, time span varying according to an individual’s health. At times, the physician would not commence drugs immediately and could adopt a wait-&-watch policy for 1-2 days to observe whether blood clot is developing. NSAID or nonsteroidal anti-inflammatory drugs (ibuprofen) could be advised for providing respite from symptoms.

Other medical advice for allaying inflammation could comprise of:

• Keeping affected leg elevated whenever doable.
• Heating pads.
• Taking walks.
• Wearing compression stocking.

All those people incapable of taking anticoagulants could require vena cava filter or diverse medications.

On-going treatment

In case DVT has affected the upper part of the leg, warfarin (like Coumadin) could be advised for three to six months and likely for even extended time spans following preliminary treatment. Long standing use of LMWH could be advised for some individuals rather than warfarin.

Subsequent to 3-6 months of use, continual use of anticoagulants could be advised for preventing DVT from relapsing.

Blood could be drawn by the doctor on a regular basis for monitoring whether the anticoagulants are functioning as expected.

Treatment for deteriorating condition

In case clot development is continuing or pulmonary embolism has occurred when on the course of anticoagulants then insertion of a vena cava filter could be done intravenously.

Expectant mothers are usually not advised oral-intake anticoagulants warfarin (like Coumadin) due to them being causal to birth anomalies. But, intravenous administration of UH or LMWH shots generally are safe all through gestational term. Oral anti-coagulants are advised soon after delivery of the baby.

When any of the symptoms that point to the presence of DVT are decipherable, then one must immediately seek professional opinion to avert matters escalating and getting grave. The direct line of treatment for DVT is the assessment and treatment of any complications that could have cropped up due to the dislocation of the clot like in pulmonary embolism or in certain situations the clot has made it way up to the brain.

Subsequent to this, certain medications are administered to assist in the dissolution of the clot. The medications work by thinning the blood thus facilitating better flow. After prompt administration of the medicines, an oral dose of the medicines are generally advised to the patient that has to be followed in their daily routine for a particular period of months. Such drugs are known to be quite potent and have a major effect on the blood, hence a battery of tests would be regularly required to be done to ensure that the dosage is correct and suiting the particular person.

Pre-emptive means to combat DVT

The development of DVT can normally be averted if one religiously follows certain deterrent measures. The chances of getting DVT could be majorly decreased by simply ascertaining that one is active and mobile through the day. By staying in a particular place for extensive periods would slow the flow of blood and lead to blood getting accumulated and coagulation taking place in the vessels that would lead to the formation of blood clot.

When one discerns the fact that one is comparatively less active, then consuming a single dose of aspirin during the day would aid in the blood thinning process. However, one must note that aspirin must always be taken along with one’s meals or on a full stomach to decrease irritation to the stomach lining.

If one is hospitalised or are going to be on an extended air travel, then it is ideal to carry along compression stocking that can be major life savers. It is important to invest in the right shape and size for the leg after consulting with the doctor who would gauge the leg size and suggest accordingly.

During protracted periods of driving, halting at a two hour interval and having short, brisk strolls and keeping oneself hydrated is crucial. Even smaller range of motions is as effectual as physical exercises and loading up on fluids would aid in maintaining the blood volume and thinness.

Maintaining idyllic weight and gaining knowledge about some effectual exercises for the foot and ankle would also be beneficial.

Those with medical history of DVT or in the greater risk bracket must steer clear from OC pills and a substitute method be adopted after medical consultation.

DVT is caused due to the formation of a blood clot typically in the deep veins of the lower portion of the leg that impedes the blood circulation in the limb region. The problem escalates when the blood clot gets dislocated and moves to the vital organs making it detrimental to one’s health.

When the clot makes its course to the lungs and hinders respiration it could lead to a fatal condition known as pulmonary embolism which is a rampant fatality generally correlated to DVT.

Women Being At Greater Risk of DVT

Women are believed to be in the high risk bracket for DVT due to varied factors. Pregnancy is considered to up the chances of ailing from DVT, particularly following child birth. To keep tab on matters, the midwife is noted to constantly question the new-mom about any kind of pain arising in the limbs during the days that follow child delivery.

The intake of contraceptive pills is also believed to raise the risk of getting DVT. Women who are on oral contraceptive (OC) pills must be discerning about the indicators of DVT and halt their intake instantly and get medical opinion when any signs of DVT surface. Doctors advice discontinuing the intake of OC pills during the weeks prior to a surgery, particularly when it is being carried out on an in-patient basis and there is imminent likelihood of immobility for a period of days or weeks.

Being obese also adds up to the risks of developing DVT with women having greater probability of being overweight in comparison to men.

Watching out for tell-tale signs of DVT

The widely prevalent signs of DVT comprise of soreness, inflammation, pain, tenderness experienced in the lower part of the limbs, though there is possibility of DVT manifesting itself in the upper portion of the limbs, hence one needs to be vigilant regarding its indicators in other areas of the body as well.

The area being affected like the calf muscles could additionally turn reddish and emanate heat due to the tissues locally present undergoing immense engorgement as the blood accumulates in the vessels. The presence of any of such indicators must elicit swift medical assistance.
