Cervical paragangliomas: single centre experience with 44 cases

Paragangliomas (PGL) are rare lesions of the neuroendocrine system; in the neck, they usually affect the carotid glomus (carotid body tumours-CBT). This retrospective analysis reports our experience in management of these lesions in patients treated by surgical resection. Between 2000 and 2014, 33 patients were surgically treated at our institution, obtaining a series of 44 cervical PGLs. Tumour characteristics, family history, diagnostic procedures, surgical treatment, short- and long-term outcomes were reviewed. A female prevalence was found (76% of cases). Familial cases occurred in 9 patients (20%); 6 presented with bilateral lesions and 1 had multiple paragangliomas. Lymph node metastasis was not found in any patient. All lesions were classified into three groups according to the latero-lateral diameter. Complete resection of the PGL was performed in all patients. Mortality was null; transitory cranial nerve deficit occurred in 20% of cases with permanent palsy in 6.7%. No perioperative stroke/TIA were observed. Surgical resection of PGL should be considered as the only therapeutic option because it can ensure complete removal of the disease. Patients with bilateral lesions and positive family history should be referred for genetic analysis. Preoperative planning of the surgical procedure by integrated diagnostic imaging and a full mastery of vascular surgery techniques are mandatory to minimise the risk of the most common postoperative complications. Long-term follow-up is recommended, particularly in patients with familial disease or sporadic lesions treated in an advanced stage

Combination of Open Subtotal Calcanectomy and Stabilization with External Fixation as Limb Salvage Procedure in Hindfoot-Infected Diabetic Foot Ulcers

Diabetic hindfoot ulcers, complicated by osteomyelitis, are associated with a high risk of major amputation. Partial calcanectomy, preceded by an effective management of the infection and of the eventual peripheral artery disease, can be considered as valid therapeutic option. We have evaluated a therapeutic protocol for diabetic hindfoot ulcers complicated by osteomyelitis, which, besides an adequate surgical debridement, considers a reconstructive pathway assisted by the positioning of a circular external fixator. We made a prospective study of a cohort of diabetic patients affected by heel ulcer complicated by osteomyelitis. All patients underwent open partial calcanectomy associated with the positioning of a circular external frame specifically designed for hindfoot stabilization and offloading. A reconstructive procedure was implemented starting with the application of negative pressure wound therapy and coverage with dermal substitute and split thickness skin grafting. From November 2014 to November 2015, 18 consecutive patients were enrolled. Mean follow-up period was 212.3 ± 64.0 days. Healing was achieved in 18 (100%) patients. The mean healing time was 69.0 ± 64.0 days. No major amputation had to be performed during the follow-up. Open partial calcanectomy associated with external fixation and skin reconstruction was as efficient as limb salvage in patients with infected lesions of the hindfoot complicated by calcaneal osteomyelitis

Surgical Management of the Charcot Foot

Charcot neuropathic osteoarthropathy is a severe complication of diabetic neuropathy. Even today the disease is difficult to recognize and treat. While in the early stages conservative therapy is extremely efficient and avoids progression into more advanced phases, when there are structural deformities and osteoarticular alterations, surgery often takes on the role of limb salvage therapy. Within this scenario, we take into consideration the physiopathology and anatomical/functional conditions that support the indication for surgery. In this paper, we review the surgical techniques, both in the field of reconstructive and prophylactic surgery aiming at correcting deformity and instability before ulcerative lesions onset, and in the field of emergent surgery once there is a complicated condition due to osteomyelitis in the bone structures

Extension and grading of osteomyelitis are not related to limb salvage in Charcot neuropathic osteoarthropathy: A cohort prospective study

Aims Charcot neuropathic osteoarthropathy (CN) represents a complication for diabetic patients which involves a progressive alteration of the osteoarticular apparatus with high risk of amputation. The aim of the study was to assess whether the localization of CN and the extent or grading of the osteomyelitis have an influence on the rate of limb salvage and the time to recovery. Methods We treated a diabetic population affected by CN complicated by ulceration and widespread osteomyelitic involvement. All patients were treated surgically to eliminate infected tissues, stabilize and correct the bone deformities. Histopathological and microbiological analyses were carried out on the bone specimens. Results Thirty-three patients affected by CN complicated by large osteomyelitic involvement of midfoot and/or ankle were treated between January 2010 and May 2014. The mean follow-up was 409,35 ± 154,06 days. Thirty patients had complete recovery (90.91%) at the end of follow-up. No difference in limb salvage rate and time to recovery was observed when stratifying the population according to CN localization, extent and grading of osteomyelitis. Conclusions In this cohort prospective study we observed a high percentage of limb salvage in patients affected by CN complicated by diffuse midfoot/hindfoot osteomyelitis. The localization of Charcot deformity and the extent/stage of osteomyelitis did not change the rate of limb salvage

Limb salvage in diabetic patients with no-option critical limb ischemia: outcomes of a specialized center experience

Objective: To describe the characteristics, the management and the outcome of a consecutive series of patients with diabetic foot lesions (DF) and no-option critical limb ischemia (CLI) treated with a multidimensional, interdisciplinary approach in a dedicated center. Research Design and Methods: The prospective database of the Diabetic Foot Unit of the Maria Cecilia Hospital (Cotignola, Italy) collects medical history, risk factors, chemistry values, angiographic data, characteristic of foot lesions, medical and surgical therapies of all patients admitted with a diagnosis of DF and CLI. All patients were followed-up for at least 1 year and/or total recovery. The primary endpoint was 1-year amputation-free survival (AFS), secondary endpoints were limb salvage and survival. Results: Between October 2014 and October 2017, 1024 patients with DF and CLI were admitted to the center. Eighty-four of them (8.2%) fulfilled the criteria for no-option CLI. At 1 year, AFS, limb salvage, and survival rates were 34%, 34%, and 83%, respectively. Lesions located proximal to the Lisfranc joint were associated with major amputation (HR 2.1 [1.2–3.6]). One-year survival of patients treated with minor procedures was significantly higher compared to patients treated with major amputation (96% vs 76%, log-rank p = 0.019). Major amputation was independently associated with mortality (HR 7.83 [1.02–59.89]). Conclusions: The application of dedicated and standardized strategies permitted limb salvage in one-third of patients with no-option CLI. Patients with stable lesions limited to the forefoot and without ischaemic pain had a greater probability to successfully receive conservative treatments. Limb salvage was associated with subsequent higher one-year survival
