The Impact

Study Design: Retrospective cohort study. Objective: Studies investigating the impact of interbody subsidence in ACDF suggest a correlation between subsidence and worse radiographic and patient-reported outcomes. The purpose of this study was to assess whether allograft subsidence assessed on CT is associated with worse cervical alignment. Methods: We performed a retrospective review of a prospective cohort of patients undergoing 1 to 3 level ACDF. Cervical alignment was assessed on standing radiographs performed preoperatively, less than 2 months postoperatively, and greater than 6 months postoperatively. Allograft subsidence was assessed on CT scan performed at least 6 months postoperatively. Patients with at least 1 level demonstrating greater than 4mm of cage subsidence were classified as severe subsidence. Student’s t-test was used to compare all means between groups. Results: We identified 66 patients for inclusion, including 56 patients with non-severe subsidence and 10 patients with severe subsidence. For the entire cohort, there was a significant increase in C2-7 Lordosis (p = 0.005) and Segmental Lordosis (p < 0.00 001) from preoperative to early postoperative. On comparison of severely and non-severely subsided levels, severely subsided levels demonstrated a significantly greater loss of segmental lordosis from early to mid-term follow-up than non-severely subsided levels (-4.89 versus -2.59 degrees, p < 0.0001), manifesting as a significantly lower segmental lordosis at >6 months postoperative (0.54 versus 3.82 degrees, p < 0.00 001). There were no significant differences in global cervical alignment parameters between patients with severe and non-severe subsidence. Conclusions: Severe subsidence is associated with a significant increase in loss of segmental lordosis, but has minimal effect on global cervical alignment parameters.

Introduction: Common femoral artery endarterectomy (CFE) is considered a relatively simple, successful and safe procedure in the literature, but major complications can occur. This retrospective study was performed in order to define characteristics contributing to success or failure after common femoral artery endarterectomy, either performed as a single or hybrid procedure. Methods: A total of 298 patients who underwent CFE in our hospital between 1 January 2011 and 1 January 2017 were included. After exclusion, 227 patients were analyzed. Patient characteristics and outcomes were derived from the patient records. Follow-up was 30 days postoperatively. Outcomes were analyzed by the chi-square test and regression analysis. Clinical success was defined as a combination of technical success, improvement in the ankle-brachial index, increased walking distance and “no complications.” Results: The procedure was clinically successful in 74.4% of the patients, and in 25.6%, a complication occurred. The Rutherford class improved in 65.1% of the patients with 1.6 (SD 1.3) class points. The ankle-brachial index improved in 44.8% of the cases, with an average of 116.6%. The most contributing factors for complications such as death, unplanned amputation, surgical site infection, thrombosis and longer hospital admission were emergency operation and a higher ASA classification. Significantly more complications also occurred in patients with renal failure, congestive heart disease, a high Rutherford classification and previous groin incision. A higher Rutherford class was the only factor correlating with an increase in the ankle-brachial index. When single CFE (48.9% of cases) and hybrid procedures (51.1%) were compared, no significant difference in success or failure was found. Conclusion: Limb ischemia requiring emergency operation and preoperative comorbidity were identified as the most important factors predictive for complications following femoral artery endarterectomy. Combining femoral endarterectomy with an endovascular intervention does not seem to increase the risk of a postoperative complication.

Background: Dysphagia is one of the most serious complications of occipitocervical fusion (OCF). The previous studies have shown that postoperative cervical alignment, documented with occipito (O)-C2 angles, C2-C6 angles, and pharyngeal inlet angles (PIA), impacted the incidence of postoperative dysphagia in patients undergoing OCF. Here, we investigated the relationship of preoperative versus postoperative cervical alignment on the incidence of postoperative dysphagia after OCF. Methods: We retrospectively reviewed the clinical data/medical charts for 22 patients following OCF (2006– 2019). The O-C2 angles, C2-C6 angles, PIA, and narrowest pharyngeal airway spaces (nPAS) were assessed using plain lateral radiographs of the cervical spine before and after the surgery. The severity of dysphagia was assessed with the functional oral intake scale (FOIS) levels as documented in medical charts; based on this, patients were classified into the nondysphagia (FOIS: 7) versus dysphagia (FOIS: 1–6) groups. Results: Seven patients (35%) experienced dysphagia after OCF surgery. Preoperative PIA and nPAS were smaller in the dysphagia group. Spearman rank correlation showed a positive correlation between preoperative PIA and FOIS and between preoperative nPAS and FOIS. Conclusion: This study suggests that preoperative cervical alignment may best predict the incidence of postoperative dysphagia after OCF.
