Further application of the bilobed flap: the split bilobed flap for reconstruction of composite posterior auricular and mastoid defects
2006
In this article a modified bilobed flap from mastoid and lateral neck skin for reconstruction of complex defects of the posteromedial surface of the auricle and mastoid skin, with the preservation of the retroauricular sulcus, is described. Reconstruction of the postero-medial auricular surface has almost never been a concern for reconstructive surgeons. It is in fact a shaded area with little aesthetic relevance and direct closure, skin grafting and even secondary healing are used for skin cancer defects repair. Also mastoid skin defects can be repaired with simple techniques such as skin grafts or transposition flaps from the remaining mastoid skin or from the neck. On the other hand, can…
Safety of Reconstructive Microsurgery in the Elderly Population: a Multicentric Prospective Study
2021
Background: Safety of reconstructive microsurgery in elderly patients is still a topic of debate, because no conclusive evidence exists that provides indications and risk evaluation in elderly patients. The purpose of this study, which the Italian Society for Plastic, Reconstructive, and Aesthetic Surgery (SICPRE) has promoted, is to evaluate the safety and the complication risk of elective reconstructive microsurgery in elderly patients as well as to identify patient- or procedure-related risk factors. The secondary aim is to evaluate the predictive role for complications of the Geriatric 8 score (G8). Methods: A total of 194 consecutive patients from 18 centers, aged 65 or older, who rece…
Epidemiological investigations of aircrew: an occupational group with low-level cosmic radiation exposure.
2012
Aircrew and passengers are exposed to low-level cosmic ionising radiation. Annual effective doses for flight crew have been estimated to be in the order of 2-5 mSv and can attain 75 mSv at career end. Epidemiological studies in this occupational group have been conducted over the last 15-20 years, usually with a focus on radiation-associated cancer. These studies are summarised in this note. Overall cancer risk was not elevated in most studies and subpopulations analysed, while malignant melanoma, other skin cancers and breast cancer in female aircrew have shown elevated incidence, with lesser risk elevations in terms of mortality. In some studies, including the large German cohort, brain c…
A wire-loop technique for implantation of an iliac branched device in a patient with previous surgery for a ruptured abdominal aortic aneurysm
2013
We described a modified technique for implanting a bridging stent-graft into an iliac branched device. A 79-year-old male who had received aortobiiliac synthetic graft surgery for a ruptured abdominal aortic aneurysm six months earlier was admitted to our unit for treatment of a left common iliac aneurysm involving the origin of the hypogastric artery. A standard technique was unsuccessful at implanting the bridging stent-graft, and therefore a wire-loop guidewire over the graft bifurcation was used to stabilize the contralateral sheaths and to complete the implantation. © Turkish Society of Radiology 2012.
Detection of flap venous and arterial occlusion using interstitial glucose monitoring in a rodent model.
2010
Background: Free tissue transfer necessitates vigilant postoperative monitoring for vessel occlusion. Unfortunately, most monitoring methods require experienced personnel and are expensive to use. Furthermore, many tests have low sensitivity, low specificity, or significant delay between vessel occlusion and detection. The authors report on a novel method of tissue monitoring that avoids these limitations by tracking interstitial glucose concentration. Methods: Vertical rectus abdominis myocutaneous flaps were elevated in adult rats based on the superior epigastric vessels. Interstitial glucose within the flaps was monitored using a transcutaneous sensor. Interstitial glucose was recorded f…
Composite graft: a simple option for nasal lining.
2007
Background We present our experience in the reconstruction of full-thickness losses of the substance of the nose using a forehead flap and a composite graft (taken from the anterior surface of the concha and adequately shaped) as both support and endonasal lining. This technique has never been described for the reconstruction of large full-thickness losses of the substance of the nose. The donor site of the composite graft in the concha is repaired by a Masson retroauricular flap. Methods This technique was used on 14 patients (age range, 52–92 years) after full-thickness excision of tumors of the distal third of the nose. Follow-up was from 1 to 4 years. All the composite grafts were rev…
Late Complication after Superficial Femoral Artery (SFA) Aneurysm: Stent-graft Expulsion Outside the Skin.
2014
A 78-year-old man presented with a 7-cm aneurysm in the left superficial femoral artery, which was considered unfit and anatomically unsuitable for conven- tional open surgery for multiple comorbidities. The patient was treated with stent-graft [Viabhan stent-graft (WL Gore and Associates, Flagstaff, AZ)]. Two years from stent-graft implantation, the patient presented a purulent secretion and a spontaneous external expulsion through a fistulous channel. No claudication symptoms or hemorrhagic signs were present. The pus and device cultures were positive for Staphylococcus aureus sensitive to piperacillin/tazobac- tam. Patient management consisted of fistula drainage, systemic antibiotic the…
External polytetrafluoroethylene reinforcement of varicose autologous vein grafts in peripheral bypass surgery produces durable bypass function
2017
Abstract Objective Use of autologous veins as peripheral bypass graft may become critical in the presence of significant varicose degeneration of the harvested vein. External support of such dilated veins with standard polytetrafluoroethylene (PTFE) prostheses was recommended as an option to use these veins for peripheral bypass. A single-center experience with this technique regarding long-term graft function, secondary reinterventions, and potential graft degeneration is presented. Methods Between January 1995 and January 2006, there were 54 patients with varicose veins who underwent 57 consecutive infrainguinal vein bypass operations with PTFE reinforcement in 57 limbs. Indications for s…
Annoyance to different noise sources is associated with atrial fibrillation in the Gutenberg Health Study
2018
Abstract Background Annoyance is a common reaction in populations exposed to environmental noise and is associated with cardiovascular diseases. We investigated for the first time the existence of an association between noise annoyance and atrial fibrillation (AF). Methods and results Cross-sectional data from 14,639 participants of the Gutenberg Health Study were collected between 2007 and 2012. Annoyance from road traffic, aircraft, railways, industrial/construction and neighbourhood noise during daytime and sleep were collected from all participants through questionnaires using a 5-point scale. AF was assessed via self-reported medical history and/or documentation of AF on the study elec…
Mid-Term Results of Endovascular Aneurysm Sealing in the Treatment of Abdominal Aortic Aneurysm With Unfavorable Morphology.
2020
Purpose: To report mid-term results of endovascular aneurysm sealing (EVAS) of abdominal aortic aneurysms (AAA) deemed unsuitable for a standard endovascular aneurysm repair (EVAR). Methods: A prospectively maintained database of 42 patients with EVAR-unfavorable anatomy treated by EVAS combined with chimney grafts in case of the proximal AAA neck shorter than 5 mm was analyzed. Early outcomes included final angiographic result, intra- and early post-operative deaths, and complications. Mid-term outcomes included all-cause mortality (ACM), aneurysm-related mortality (ARM), patency of the stents, occurrence of endoleaks, serious complications and graft failures defined as the AAA growth of m…
