valves. - Correct Answerscalves; leaflets
What tests are used to detect DVT? - Correct Answers- look, feel, interview patient

venography
Conventional catheter diagnostic venography is limited to specific scenarios: - Correct Answers- prior
placement of IVC filters
- evaluation of central DVT in the proximal arms and thorax
- prelude to interventions, such as thrombolysis, thrombectomy, and stent placement
, - in obese patients or patients with a markedly swollen leg
- when other modalities don't or can't solve a specific problem

venography for the pelvic and thigh veins, but is _________ accurate for the calves. - Correct
Answershigh; less
