Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	*Basis of Presentation* The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2022, filed with the Securities and Exchange Commission (the “SEC”) on March 27, 2023. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for fair presentation have been included. Operating results for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023. For further information, refer to the consolidated financial statements and footnotes thereto included in Item 8 of the Company’s most recent Annual Report on Form 10-K. The preparation of these consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ materially from those estimates. The Company assessed certain accounting matters that generally require consideration of forecasted financial information in context with the information reasonably available to the Company as of March 31, 2023 and through the date of this report filing. The accounting matters assessed included, but were not limited to, the allowance for expected credit losses and the carrying value of intangible and long-lived assets. At the annual and special meeting of the Company’s shareholders held on May 10, 2023, the Company’s shareholders granted the Company’s Board of Directors discretionary authority to implement a consolidation of the issued and outstanding common shares of the Company (a "Reverse Stock Split") and to fix the specific ratio within a range of one-for-five (1-for-5) to a maximum of a one-for-fifteen (1-for-15) consolidation. On May 11, 2023, the Company filed an amendment to the Company’s Certificate of Incorporation to implement the Reverse Stock Split based on a one-for-fifteen (1-for-15) consolidation ratio. The Company’s common shares began trading on the Nasdaq Capital Market on a split-adjusted basis under the Company’s existing trade symbol “VERO” at the opening of the market on May 12, 2023. In accordance with U.S. GAAP, the change has been applied retroactively. Amounts reported in thousands within this report are computed based on the amounts in U.S. dollars. As a result, the sum of the components reported in thousands may not equal the total amount reported in thousands due to rounding. Certain columns and rows within tables may not add due to the use of rounded numbers. Percentages presented are calculated from the underlying numbers in dollars.

ASU 2020-06 reduces the number of accounting models for convertible debt instruments by eliminating the cash conversion and beneficial conversion models. The diluted net income per share calculation for convertible instruments will require us to use the if-converted method. For contracts in an entity’s own equity, the type of contracts primarily affected by this update are freestanding and embedded features that are accounted for as derivatives under the current guidance due to a failure to meet the settlement conditions of the derivative scope exception. This update simplifies the related settlement assessment by removing the requirements to (i) consider whether the contract would be settled in registered shares, (ii) consider whether collateral is required to be posted, and (iii) assess shareholder rights. ASU 2020-06 is effective for the Company on January 1, 2024, with early adoption permitted. ASU No. 2020-06 can be adopted on either a fully retrospective or modified retrospective basis. The Company is currently assessing the impact of applying this guidance as well as when to adopt this guidance.
