Completely percutaneous endovascular aortic aneurysm repair (PEVAR) has become more common, using the suture-mediated “preclose” technique. The rate of periprocedural, iatrogenic, acute deep vein thrombosis (DVT), hitherto unknown, was found to be low for this approach, according to a study reported by Dr. Courtney E. Morgan and her colleagues at the Northwestern University, Chicago.
The researchers assessed 52 consecutive patients (44 men) with a mean age of 73 years, who underwent PEVAR at their center. Only 6% had a prior history of DVT (J Vasc Surg. 2015 Aug; 62:351-4).
Acute DVT was seen in four patients on postoperative day 1. These four DVTs comprised one femoropopliteal, and three calf DVTs. Three of these patients had associated risk factors: history of DVT (two patients); active smokers (one patient); and obesity (body mass index greater than 30 kg/m2 in all three patients).
At 2 weeks postoperatively, 75% of the DVTs had resolved.
“We found an overall rate of proximal DVT of 4% after PEVAR, which increased to 13% when calf-vein DVTs were included. Most patients with postoperative DVT had preexisting risk factors, which suggests that routine duplex ultrasound screening after PEVAR is not necessary unless there exist preclinical risk factors or postprocedural clinical indications suggestive of DVT,” the authors concluded.
Two of the researchers have received funding and/or served as speakers/consultants for device companies involved in EVAR.
