Spontaneous Regression of an Unruptured Arteriovenous Malformation Due to Drainer Vein Thrombosis in a Patient with Protein S Deficiency: A Case Report and Literature Review. NMC Case Rep J 2023; 10:221-226. [PMID: 37621748 PMCID: PMC10446868 DOI: 10.2176/jns-nmc.2023-0056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Accepted: 05/17/2023] [Indexed: 08/26/2023] Open
Abstract
Spontaneous regression of an arteriovenous malformation (AVM) is a rare condition observed in 0.3%-1.3% of patients with AVMs and is most likely caused by hemorrhagic events. The regression of an unruptured AVM is rarer than that of a ruptured AVM. Moreover, due to its low frequency of occurrence, the etiology and natural course of spontaneous regression of an AVM is still unclear. This is the first report presenting a case of a spontaneous regression of an unruptured AVM caused by a gradual drainer vein thrombosis that was suspected to result from hypercoagulability due to protein S deficiency.

Ahmed JO, Ahmed SA, Hassan MN, Kakamad FH, Salih RQ, Abdulla BA, Rahim Fattah FH, Mohammed SH, Ali RK, Salih AM. Post COVID-19 neurological complications; a meta-analysis. Ann Med Surg (Lond) 2022; 76:103440. [PMID: 35261766 PMCID: PMC8891214 DOI: 10.1016/j.amsu.2022.103440] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2022] [Revised: 02/19/2022] [Accepted: 02/27/2022] [Indexed: 12/12/2022] Open
Abstract
Introduction Despite numerous studies regarding neurological manifestations and complications of COVID-19, only a few cases of neurological consequences following complete recovery from SARS-CoV-2 infection have been described. Objectives The current study aims to present a quantitative meta-analysis of published studies regarding the post-infectious neurological complications of COVID-19. Data sources The Web of Science, PubMed, MEDLINE on OVID, and Google scholar were searched for English-language researches published after January 1, 2020. Result The review of the literature revealed 60 cases - of which 40 (66.7%) cases were male, and 18 (30%) were female. The average age was 44.95 years. Overall, 17 (28.3%) patients had comorbid conditions. Twenty-four (40%) patients were hospitalized during an active COVID-19 infection. The average interval from the COVID-19 infection to the onset of neurological sequelae was 33.2 days. Guillain-Barre syndrome was the most commonly reported neurological condition (15, 25%). Conclusion Despite recovery from acute infection, the pandemic highlights the significance of ongoing, comprehensive follow-up of all COVID-19 patients - even those initially were believed to be asymptomatic. SARS-CoV-2 most commonly associates with pneumonia. However, new studies have indicated that many other organ systems can be involved. Also various neurological sequelae in COVID-19 individuals have been identified. The specific relationship between the infection and neurological disorders remains unknown. In this study, metadata were discussed regarding post COVID-19 neurological complications.
