Item Reversal of Severe Vasospasm Causing Transradial Angiogram Catheter Entrapment by Low Dose Sedation(Acıbadem Mehmet Ali Aydınlar Üniversitesi, 2015-04-01) Zencirci, Ertuğrul; Değirmencioğlu, Aleks; Karakul, GültekinABSTRACT One of the major disadvantages of the transradial approach during cardiac interventions is radial artery spasm. Severe vasospasm of the radial artery causing catheter entrapment is less frequently encountered and its man agement has rarely been reported. Herein, a 72-year-old female patient who was scheduled for an elective left heart catheterization due to exer tional angina pectoris is reported. During transradial diagnostic coronary angiography, catheter entrapment occurred due to severe vasospasm of the radial artery. Reversal of severe vasospasm and release of entrapped cath eter was not possible until low dose sedation with intravenous midazolam was given. This case report demonstrates that low dose sedation with intra venous midazolam could be used effectively to reverse resistant vasopasm of the radial artery during transradial interventions.Item Recent Developments in Above-Knee Prosthetics and the Importance of Energy Recovery in Transfemoral Amputee Gait(Acıbadem Mehmet Ali Aydınlar Üniversitesi, 2015-04-01) Bayram, Hande ArgunsahABSTRACT Objectives: Use of a spring as an energy harvest/release mechanism for transfemoral prosthetics designs is gaining traction. While springs theo retically can minimize the energy flow deficiency during the stance phase knee flexion, there are problems associated with controlling the release of energy harvested by springs. The purpose of this review is to discuss the importance of controlled energy flow at the knee joint, recent attempts to harvest/return energy and the emphasis on the role of the ankle prosthesis in achieving assisted gait. Study Design: Literature Review Methods: Use of a spring in emerging prosthetic knee designs are presented in terms of their energy regeneration abilities along with their advantages and limitations. Results: Use of a spring in knee prosthetics can cut power demand signifi cantly as they mimick the musculotendonous structures by harvesting and returning needed energy. Conclusions: Controlled energy flow at the knee joint could not only provide natural movement of the amputated limb but could also create positive power peaks at the knee joint. These features cannot be produced by any of the current generation of controlled damping prosthetic knees.Item Kalvarium Metastazı Ayırıcı Tanısında Enostoz: Olgu Sunumu(Acıbadem Mehmet Ali Aydınlar Üniversitesi, 2015-04-01) Güdük, Mustafa; Sav, Aydın; Vardareli, Erkan; Peker, SelçukÖZET Enostozlar (kemik adaları), genelde insidental olarak bulunan, herhangi bir klinik şikayet yaratmayan kemik lezyonlarıdır. Ayırıcı tanılarında primer kemik tümörleri ve metastazlar mevcuttur ve tanıya yönelik çalışmalarda kafa karıştırıcı olabilmektedirler. Olgu sunumumuzda metastaz ön tanısı ile opere edilen 65 yaşındaki erkek enostoz olgusu sunulmaktadır.
