Appellant Rene Flores appeals a memorandum decision of the United States Court of Appeals for Veterans Claims (“Veterans Court”), which affirmed a Board of Veterans’ Appeals (“Board”) decision denying Mr. Flores’s application to reopen his claim. See J.A. 5-7 (Veterans Court decision); J.A. 9-23 (Board decision). On appeal, Mr. Flores argues that the Department of Veterans Affairs (“VA”) has not produced certain medical records that Mr. Flores contends exist and are missing from the rec-ord. 1 Appellee Secretary of Veterans Affairs responds that this court lacks jurisdiction over Mr. Flores’s appeal. In the alternative, the *596 Secretary argues that the Veterans Court and Board both properly found that the record contradicts Mr. Flores’s assertions that any medical records are missing. We agree with the Secretary on the question of jurisdiction and dismiss Mr. Flores’s appeal for lack of jurisdiction.

“Our jurisdiction to review the decisions of the [Veterans Court] is limited by statute.” Summers v. Gober, 225 F.3d 1293, 1295 (Fed.Cir. 2000). While this court is authorized to “decide all relevant questions of law, including interpreting constitutional and statutory provisions,” we cannot adjudicate “(A) a challenge to a factual determination, or (B) a challenge to a law or regulation as applied to the facts of a particular case,” unless a constitutional issue is presented. 38 U.S.C. § 7292(d).

The Veterans Court did not interpret or decide the validity of a statute or regulation in rendering its decision, a fact that Mr. Flores concedes. See Appellant’s Br., item 2 (checking the “No” box in response to “[d]id the Court of Appeals for Veterans Claims decision involve the validity or interpretation of a statute or regulation?”). Mr. Flores also rightly admits that the Veterans Court did not decide a constitutional issue. See id. item 3 (checking the “No” box in response to “[d]id the Court of Appeals for Veterans Claims decide constitutional issues? ). At most, Mr. Flores argues that the Veterans Court misapplied 38 U.S.C. § 5108, which requires the VA to reopen a claim if new, material evidence is presented.

Finally, the Veterans Court concluded that the VA satisfied its duty to assist Mr. Flores in obtaining the relevant records. This is also an issue over which we do not have jurisdiction, as it is not a question of constitutional or statutory interpretation. See Glover v. West, 185 F.3d 1328, 1333 (Fed.Cir. 1999); 38 U.S.C. § 7292(d). Thus, although Mr. Flores remains concerned that certain records are missing, the Veterans Court was the last court that could consider that issue.

Accordingly, we lack jurisdiction over Mr. Flores’s appeal, and his case is dismissed. 38 U.S.C. § 7292(d).
