In operation of increasing the technology day by day as increasing the complexity of telecommunication network system. As the subscriber become more interested to get the advance and easy and fastest technology of the cellular network. There is a evolution take place in order to get the advance technology in the wireless communication (1G to 5G). In addition, the main purpose of the wireless communication is to reduce the human effort. We are in the midst of major change in the wireless network and the primary objective of wireless network operation has been to satisfy the users need. As this paper represent the Generation of the wireless communication, the network architecture of wireless communication and the hardware and software logics evolution of the wireless communication, Network Security and the Future Technologies 6G and 7G.
Background
Spontaneous retroperitoneal haemorrhage (SRH) is a rare cause of retroperitoneal haemorrhage in patients who are on anticoagulants or antiplatelet agents or both.
Case summary
We report here a rare and catastrophic complication of use of anticoagulants and antiplatelet drugs in a case undergoing coronary angioplasty. The patient had multiple coronary risk factors and developed acute myocardial infarction with pulmonary oedema and hypotension during hospitalization for treatment of lower respiratory tract infection and diabetic ketoacidosis. He underwent successful angioplasty of the culprit vessel but later developed hypotension attributable to retroperitoneal haemorrhage. No bleeding site was identified despite extensive evaluation of the aorta and iliac vessels.
Discussion
A diagnosis of SRH is considered when a patient on anticoagulants or antiplatelet drugs develops retroperitoneal haemorrhage without any specific identifiable site of bleeding in the retroperitoneum. Diffuse vasculopathy and atherosclerosis or vasculitis of the small vessels in the retroperitoneum may result in rupture of the most friable vessels and result in bleeding. Intense cough, forceful vomiting or sneezing may also be responsible for traumatizing the vessels and resulting in bleeding. Most cases recover with conservative management but some may benefit from interventional occlusion of the leak or surgical decompression in cases of abdominal compartment syndrome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
