Final answer:
In embalming, a thrombus can cause diminished distribution and intravascular resistance, leading to uneven preservation of the body. The clot obstructs the flow of embalming fluid, which can result in areas of accelerated decomposition.
Step-by-step explanation:
A thrombus, an aggregation of blood components such as platelets, red blood cells, and potentially white blood cells typically trapped within a mass of fibrin strands, can cause serious complications in embalming. When present, particularly as mural or occlusive thrombi, they can adhere to blood vessel walls or block blood flow, respectively. The most pertinent complication for embalming processes would be diminished distribution and intravascular resistance. This results from the thrombus impeding blood flow, which is necessary for the even distribution of embalming fluid. It can also create areas of tissue that may not be properly preserved, leading to uneven preservation and potentially accelerated decomposition.
In the case of deep vein thrombosis (DVT), the risk of a piece of the thrombus breaking free to become an embolus, which can lead to a pulmonary embolism (PE), is a significant health concern. However, in the context of embalming, the issue is primarily the obstruction of vascular pathways.
