Case report: Navigating the challenges: successful mechanical thrombectomy in a case of persistent primitive hypoglossal artery

Persistent primitive hypoglossal artery (PPHA) is a highly uncommon abnormal connection between the internal carotid artery (ICA) and vertebral artery (VA), with reported incidences ranging from 0.027 to 0.26%. Attempting endovascular intervention in such cases presents a considerable challenge as it carries a higher risk of embolization and other procedure-related complications that may affect a wide area of the brain. We present a case study involving the utilization of mechanical thrombectomy (MT) to treat an ischemic stroke in the M1 segment of the middle cerebral artery (MCA) despite the presence of PPHA. Performing mechanical thrombectomy in an anomalous vascular connection is feasible; however, it necessitates heightened vigilance, thorough knowledge of the anatomy, and utmost caution

An alternative patellar resurfacing technique in knee replacement: patellofemoral fascial interposition arthroplasty

The present study reports the early clinical results of 38 osteoarthritic patients (38 knees) who were treated by total knee replacement in conjunction with patellofemoral fascial interposition arthroplasty (PFIA). After the femoral and tibial components were inserted, a fasciotendinous graft was harvested from the anterior surface of the quadriceps tendon and sutured around the articular surface of the patella. The patients were followed-up for a minimum of 24 months. The durability of the fascial graft was assessed radiographically by addition of a wire suture marker placed into the fascia in the first five patients. Patients were evaluated using the Hospital for Special Surgery (HSS) knee-rating system, and anterior knee pain was assessed using specific patellofemoral-related questions. The average HSS knee score improved from 61 points preoperatively to 92 points at 24 months' follow-up (P < 0.001). Twenty-five patients (65.7%) had anterior knee pain preoperatively, and seven patients (18.4%) revealed anterior knee pain at their last visits (P < 0.001). The position of the markers in the fascial grafts did not show any change during radiological follow-ups. Our data suggest that, PFIA provides good pain relief and it may be an alternative resurfacing technique avoiding the complications of patellar components

Effect of End-to-side Repair of Proximal Nerve Stumps of Transected Peripheral Nerves on the Development of Neuroma (Experimental Study)

Objective: Neuroma is a psychologically and physically disabling problematic condition without any current standard therapy. For that reason, we investigated whether end-to-side anastomosis of the proximal end of the transected nerve into the adjacent nerve will prevent the development of neuroma in different types of nerve injuries. Study design: In this study, hind legs of 18 Sprague - Dawley female rats were used. Six groups were formed. In group I, peroneal nerves were transected and its proximal end was attached end-to-side through the epineural window to the adjacent tibial nerve. In group II, contrary to group I, an epineural window was created in the tibial nerve and the same number of sutures were employed. In group III, tibial nerve was transected proximal to the end-to-side repair site, whereas in group IV, distal segment of the nerve was cut, and an end-to-end repair procedure was repeated. In group V, unlike group I, an approximately 1-cm segment was resected and removed distal (from tibial nerve) to the end-to-side repair site. In group VI, an epineural window was created in the tibial nerve and the same number of sutures were used, and also a 1-cm distal nerve segment was resected. The rats were followed for 2 months, and then all of the groups were evaluated histopathologically, and weights of the posterior muscle groups of hind legs were evaluated. Findings and Conclusions: No neuroma formation was observed in the proximal stumps of peroneal nerve segments in end-to-side repair sites in groups I, III, IV, and V, and proximal stumps of the tibial nerve in group V. In group VI, neuroma formation was observed in the proximal end of the tibial nerve. When weights of the posterior muscle groups of hind legs in groups I and II were comparatively assessed, statistically significant difference was not detected. In conclusion, based on histological data obtained for proximal nerve ends and segments distal to the end-to-side repair sites, we think that end to side neurorrhaphy of the proximal end of the damaged nerve to adjacent nerve will prevent the development of neuroma without injuring the intact nerve segment. © American Association for Hand Surgery 2007
