Hypertension
|
The categories of blood pressure (category: systolic mmHg(S), diastolic mmHg(D)) as: optimal (S < 120, D < 80), normal (S < 130, D < 85), high normal (S 130–139, D 85–89), stage1(mild) (S 140–159, D 90–99), stage 2 (moderate) (S 160–179, D 100–109), and stage 3 (severe) (S ≥ 180, D ≥ 110) [29].

|
Body mass index
|
Weight in kilograms divided on height in meters squared (kg/m2). Categories as: underweight (Less than18.5 kg/m2), normal (Between 18.5 kg/m2 and 24.9 kg/m2), and overweight (More than 25 kg/m2) [29].
|
|
Number of femoral punctures
|
The number of groin punctures to achieve proper femoral artery cannulation.
|
|
Oozing
|
Presence of any leakage of blood from the puncture site. The blood tainted area is < 3 × 3 cm2 on the gauze, but it does not reach the level of bleeding [18].
|
|
Ecchymosis (bruising)
|
Presence of any skin discoloration associated with pain and minor swelling [16].
|
|
Bleeding
|
Considered present when there is more than 2 g/dl loss from baseline of hemoglobin from puncture site [18].
|
|
Hematoma
|
Swelling mass surrounding the puncture site hard, palpable, and tender (Small hematoma: < 5 cm in diameter, Large hematoma: > 5 cm in diameter) [17].
|
|
Pseudoaneurysm
|
Pulsatile mass; presence of a palpable mass with corresponding movement to systole and diastole diagnosed by Doppler ultrasound detecting flow [14].
|
|
Retroperitoneal bleeding
|
Moderate to severe back pain associated with hypotension and tachycardia diagnosed by computed tomography [17].
|
|
Femoral occlusion (Thrombosis)
|
Complete occlusion of the femoral vessel as detected by the absence of distal foot pulses, and confirmed by Doppler ultrasound detecting flow [17].
|
|
Arteriovenous fistula
|
Abnormal communication between the femoral artery and vein produces palpable thrill and bruit sound confirmed by a stethoscope placed over the puncture site, and by Doppler ultrasound detecting flow [17].
