____ access is a critical component of vascular and interventional procedures.
Arterial
26
The most common arterial access points are:
•Femoral artery •Radial artery •Brachial artery
27
Other access points, such as _____, are used for specific peripheral vascular interventions.
pedal or antegrade arterial access
28
Most common site for arterial interventions
Femoral Artery Access
29
Preferred for lower extremity interventions, including recanalization of tibial or femoropopliteal occlusions
Femoral Artery Access
30
•Visible via ultrasound but manual compression is less effective. •Used when femoral access is not feasible (e.g., severe aortoiliac disease).
Brachial Artery Access
31
•Increasingly preferred in both cardiology and interventional radiology.
Radial Artery Access
32
is a collection of clotted blood that forms outside of a blood vessel.
Hematoma formation
33
•Occurs when the arterial puncture site fails to seal.
Pseudoaneurysm
34
•Tear in the tunica intima causing a false lumen.
Arterial Dissection
35
•Formed when both the artery and vein are punctured.
Arteriovenous Fistula (AVF)
36
•Due to plaque disruption or atheroembolism.
Distal Ischemia
37
Only patients with _____ collateral circulation are candidates for radial access
adequate
38
Inadequate ulnopalmar patency (<2% of patients)
Grade D
39

41
42
43
44
involves the placement of a catheter into a large vein to provide reliable access to the central circulation.
Central venous access
45
•Inserted via peripheral veins (basilic, cephalic, or brachial).
Peripherally Inserted Central Catheter (PICC)
46
•Common insertion sites: Internal jugular (IJ), subclavian, or femoral veins. •Indications: Emergency access, short-term use. 10 days to 2 weeks. •Higher risk of dislodgement and infection over time.
Non tunneled Central Line
47
•Inserted with a subcutaneous tunnel to reduce infection risk and improve catheter stability.
Tunneled Central Line
48
•Fully implanted under the skin with a reservoir.
Implantable Port (Port-a-Cath)
49
Occur during the procedure (uncommon due to image guidance).
Immediate Complications
50
Typically involve catheter malfunction.
Late Complications
51
Occurs when air enters the sheath after dilator removal.
Air embolism
52
Kinking due to acute catheter angles.
Catheter Malfunction
53
Layering of material around the catheter tip.
Fibrin Sheath Formation
54
is a common nonvascular procedure performed by interventional radiologists (IR).
Percutaneous enteric access
55
1.Enters the stomach through the abdominal wall. 2.Suitable for patients with normal anatomy and small bowel motility.
Gastrostomy (G-tube)
56
1.Tip resides in the jejunum. 2.Ideal for patients with severe reflux or gastric outlet obstruction.
Gastrojejunostomy (GJ-tube)
57
1.Direct entry to bowel through the abdominal wall. 2.Used for patients with prior gastrectomy or biliary-jejunal anastomosis.
Jejunostomy (J-tube) or Cecostomy
58
•is a minimally invasive procedure to drain fluid collections within the body. •It has largely replaced open surgical drainage due to lower complication rates and better clinical outcomes.
Transcatheter fluid drainage
59
: Commonly due to recent surgery or infection along the bowel.
Abscesses
60
Generally should not be drained unless infected, as sterile hematomas are better left undisturbed.
Hematomas
61
refer to the accumulation of fluid within the chest cavity. The most common type is pleural effusion
Intrathoracic fluid collections
62
•Long-term, tunneled pleural drains for patients with malignant effusions. •Designed for home use with periodic self-drainage or home health assistance.
PleurX Catheters
63
•Caused by thoracic duct trauma, often following cardiothoracic surgery. •Diagnosed by milky-white drainage and positive chylomicrons in pleural fluid.
Chylothorax
