This paste might have destroyed any residual cancer cells not detected by the pathologist. Missing epidermal margins. Ideally, the Mohs section should include 100% of the epidermal margin ...

This is because head vessels of the aortic arch supplying blood to the brain cannot be covered and for this reason, there is often an inadequate landing zone for stent-graft delivery. A hybrid repair strategy offers a reasonable choice for treating such patients. A commonly used hybrid repair procedure is the "frozen elephant trunk repair". [20]
Many details must be discussed between the artist and scientist before a final drawing can be completed, and additional preliminary drawings must be prepared in order to work out aesthetic details. Pen and ink (often a flex nib fountain pen) line illustrations are clean, crisp, clear, and inexpensive to produce, making them ideal for biological ...
An anastomotic leak is a fault in the surgical connection between the two remaining sections of bowel after a resection is performed. This allows the bowel contents to leak into the abdomen. Anastomotic leaks may cause infection, abscess development, and organ failure if untreated. Surgical steps are taken to prevent leaks when possible.
Pericardiocentesis can be used to diagnose and treat cardiac tamponade. [3] [4] Cardiac tamponade is a medical emergency in which excessive accumulation of fluid within the pericardium (pericardial effusion) creates increased pressure. [5]
