Venous leak is an inability to maintain an erection in the presence of sufficient arterial blood flow through the cavernosal arteries of the penis. [6] The defect lies in the excessive drainage of veins in the cavernosal tissue of the penis, which undermines normal erectile function.
Catheter access, sometimes called a CVC (central venous catheter), consists of a plastic catheter with two lumens (or occasionally two separate catheters) which is inserted into a large vein (usually the vena cava, via the internal jugular vein or the femoral vein) to allow large flows of blood to be withdrawn from one lumen, to enter the dialysis circuit, and to be returned via the other lumen.
Tunneled catheters have multiple channels called lumens which lay exposed on the surface of the skin. These lumens are the access points when the catheter is used. Tunneled catheters can be single, double, or triple lumened. Removal of a tunneled catheter is a simple procedure requiring only local anesthetic. A bandage is applied to the site to ...
In some situations, venous access is obtained by inserting catheters into the large central veins of the trunk of the body such as the internal jugular, subclavian, or femoral veins. This type of venous access is performed with central venous catheters (CVCs) , and is required in certain situations where peripheral access is inadequate.
Femoropopliteal bypass surgery is mainly used to treat cases of femoral artery blockage that cause more severe symptoms that restrict completion of daily tasks such as peripheral artery disease and claudication, or cases that have not responded well to other treatment options . Before surgery is considered, adjustments are made to lifestyle ...
Cyproterone can cause side effects such as fatigue, low mood, and fulminant hepatitis. Orchiectomy allows individuals to stop taking these medications and avoid these adverse effects. [1] It is also an alternative for trans women who have contraindications to antiandrogens and is a minimally invasive procedure to eliminate testosterone levels. [11]
Implanted central venous catheter Implanted port. The "nipples" which define the clinician's target area are here readily discerned. Gripper needle inserted in port. An implanted central venous catheter, also called a port a "cath" or "port-a-cath", is similar to a tunneled catheter, but is left entirely under the skin and is accessible via a ...
A peripherally inserted central catheter (PICC or PICC line), also called a percutaneous indwelling central catheter or longline, [1] is a form of intravenous access that can be used for a prolonged period of time (e.g., for long chemotherapy regimens, extended antibiotic therapy, or total parenteral nutrition) or for administration of substances that should not be done peripherally (e.g ...
