March Internal Vascular Series: DVT

During a traffic jam, the torrent of vehicles trying to get out of the area make it nearly impossible for other cars to come in. 

Deep vein thrombosis (DVT) is like a major traffic jam in a large vein in the body, usually in the legs – except the traffic jam is caused by a blood clot that develops.  Blood can’t get into the leg because there is so much blockage with the blood trying to get out of the leg.  The result?  A leg that suddenly swells up – sometimes even doubling in size.  If the clot breaks off, it can be life-threatening if left untreated.  Pulmonary embolism (PE) most commonly results from a clot that migrates to the lung, a process called venous thromboembolism (VTE).

DVT and its complications claim the lives of more people each year in the U.S. than breast cancer and AIDS combined!  A whopping 600,000 Americans are diagnosed with DVT annually, making it the third most common cardiovascular disease.  VTE is the leading cause of preventable hospital death.

With a problem this prevalent, TMC has developed one of the busiest programs in the nation for minimally invasive DVT interventions.  Vascular surgeon Dr. Matthew Namanny from Saguaro Surgical estimates 80 to 200 of these procedures are done at TMC every year.  All are done in TMC’s hybrid operating room.

DVT awareness is gaining steam, thanks to efforts on all levels, from the nationwide Coalition to Prevent DVT, to the local level – where Dr. Namanny says educating others is not just part of the job, rather a true passion for him and his colleagues.  “We must take a multidisciplinary team approach to take care of these patients.  We all have to look for them and ask about risk factors,” he said.

Namanny in action 2Driving that point home was one of the main messages of Tucson Medical Center’s internal vascular series for the month of March, which focused on DVT.  Dr. Namanny spoke to health care workers who play a role in preventing these clots at the patients’ bedside.

Who’s at risk for blood clots?  Anyone.  “I’ve had patients who were in their teens all the way to patients in their 80’s and 90’s.  It’s not just a disease that affects older people.  It does have an increased prevalence with age, people who travel and take long flights, people who are immobilized.  Patients who have had major surgery, trauma, cancer, or who have had DVT in the past also have a higher risk, as do pregnant women, and any woman on oral contraceptives,” Dr. Namanny said.

The symptoms can be very subtle, he explains, and can range from minor pain and swelling to legs that are massively swollen to the point where circulation is compromised.  If patients have had pulmonary embolism, they can also be short of breath. 

DVT is easier to treat the earlier it’s caught.  Patients are started on blood thinners right away.  If symptoms are severe, they’re evaluated for intervention and clot removal.  Treatment options have really advanced, as the problem can typically be fixed during an outpatient procedure.

  1. I have no family hrotsiy of DVT and got this 18 months back in my lower left limb.. was not able to move for a month then with the continuous dosage of LMWH there was improvement. Later a drug called ACITROM was advised to me by my DOC which i regulary had for next 8-10 months and then stopped. Now I am on NO medication ( since last 7-8 months) and not going to the Doc . Still there is a little pain in the lower limb if i walk a bit more than the usual.. seems i have to live with it now.
