Peripheral diabetic neuropathy (PDN) is one of the major complications arising in patients with diabetes. Since PDN is traditionally considered an irreversible disorder, treatment has been aimed to prevent the development of complications. In a novel concept, however, it is postulated that decompression surgery of the affected nerve may reverse the natural course of PDN. In this review, we will discuss experimental and human studies that addressed the value of nerve decompression surgery in PDN. Furthermore, we report on the awareness of this novel treatment strategy among medical professionals that are primarily involved in diabetes care.
Repetitive trauma to the hypothenar eminence can cause the ulnar artery to become aneurysmal, thrombose, or send emboli to the digital arteries. The symptoms and signs are also known as the hypothenar hammer syndrome. We postulate that an arterial autograft is a superior conduit to the traditional vein graft. In this article, we report 3 cases (2 in 1 patient) of reconstruction of the distal ulnar artery with the descending branch of the lateral circumflex femoral artery (LCFA). Two patients, ages 45 to 50 years, had severe ischemic complaints of the ulnar fingers. Arteriograms confirmed occlusion of the distal ulnar artery without direct perfusion of the superficial palmar arch. All reconstructions were carried out with the descending branch of the LCFA. From the ulnar artery at wrist level to the superficial palmar arch and the involved common digital arteries. Patency was certified during follow-up with color-coded Duplex sonography at 6 to 28 months. Preoperative complaints like cold intolerance and other ischemic symptoms disappeared.
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.
