ABSTRACT

OBJECTIVES: This study aims to present the importance of a multidisciplinary approach to radiofrequency ablation (RFA) treatment in osteoid osteoma (OO) patients by a team of experts in their field in preventing recurrence and complications. PATIENTS AND METHODS: For this retrospective study, a team of two orthopedists, two interventional radiologists, and one anesthesiologist was established in January 2013 to manage the diagnosis, follow-up, and treatment process of patients with OO at Bakirköy Dr. Sadi Konuk Training and Research Hospital. A total of 27 patients (15 males, 12 females; mean age 22.9 years; range, 9 to 54 years) were treated by this team between February 2013 and September 2016. The anatomic localization included iliac crest in four patients, the femur in 12 patients, fibula in two patients, humerus in three patients, radius in one patient, tibia in three patients, talus in one patient, and metacarpal in one patient. The procedures were carried out by the same interventional radiologists, same orthopedic surgeons, and same anesthesiologist in the computed tomography (CT) unit under aseptic conditions. After appropriate anesthesia for the localization of OO, the patient was positioned on the CT bed and the localization of the lesion was confirmed with a CT scan mapping. Then, a bone penetration cannula was advanced and bone cortex was penetrated with a charged motor and Kirschner (K)-wire. When the cannula reached the nidus, it was replaced with RFA probe. Ablation of the nidus was performed for five minutes at 90°C. RESULTS: The mean follow-up period was 46 months (range, 25 to 66 months). Patients were evaluated with visual analog scale (VAS) scores preoperatively and at postoperative 15th day, sixth month, and first year. In the last evaluation of the study data, the patients were called by telephone and questioned whether there were any changes in their final status. The mean preoperative VAS score was 7.2. The mean postoperative VAS scores of the 15th day, sixth month, and first year were 1.3, 0.6, and 0, respectively. In the last follow-up, the OO-related pain completely disappeared and none of the patients had any recurrence. There was a significant difference between preoperative and postoperative 15th day and sixth month VAS score measurements. CONCLUSION: Radiofrequency ablation treatment of OOs is a minimally invasive, safe, low-cost, and efficient method. We believe that with experienced teams and appropriate planning, RFA will take part in practice as the standard treatment of OO.

ABSTRACT

BACKGROUND: Tigertriever (Rapid Medical, Yoqneam, Israel) is a new design of stent retriever. PURPOSE: To evaluate the feasibility, safety, and efficacy of the Tigertriever in patients with acute ischemic stroke who have undergone mechanical thrombectomy. MATERIALS AND METHODS: Two different techniques-namely, standard unsheathing (SUT) and repetitive inflation-deflation (RID) techniques, were used. Modified Thrombolysis in Cerebral Infarction (mTICI) scores of 2b and 3 were considered as successful recanalization. RESULTS: A total of 61 thrombectomy procedures with Tigertriever were retrospectively evaluated. The mean age of patients was 60.7 years and their National Institutes of Health Stroke Scale score was 14.7. Overall, the percentage of patients with a mTICI score of 0, 2b, and 3 was 24.6, 26.2, and 49.2, respectively. Successful recanalization and first-pass success rates were 75.4% and 37.7%, respectively. There were no statistical differences between the results of the SUT and RID techniques. No vessel rupture, dissection, or device detachment was observed. The number of patients with a good clinical outcome (modified Rankin Scale score 0-2) was 17 (27.9%). CONCLUSION: Our results showed that the Tigertriever device is safe and efficient for mechanical thrombectomy.

ABSTRACT

BACKGROUND: The present study is an evaluation of the efficacy of endovascular treatment in emergency setting for patients with acute peripheral and visceral arterial injury secondary to penetrating or blunt trauma. METHODS: Twelve patients (11 men) aged 35.8±11.3 years (range: 18-56 years) with penetrating or blunt trauma who underwent endovascular treatment in our department between March 2010 and June 2014 for peripheral and visceral arterial injury were retrospectively reviewed. Selective coil embolization was performed on 11 patients and particle embolization of the injured vessel was performed on 1 patient. Criteria for endovascular treatment included active extravasation or pseudoaneurysm on contrast-enhanced computed tomography and decrease in hemoglobin level or temporary hemodynamic instability. RESULTS: Arterial injuries were secondary to penetrating injury due to gunshot wound in 4 patients and stab wound in 5, and blunt abdominal injury as result of traffic accident in 3 patients. Traumatic lesions were in the right hepatic artery (n=3), left hepatic (n=2), right hepatic and right renal (n=1), left inferior epigastric (n=2), left facial (n=1), anterior tibial (n=1), and deep femoral (n=1) arteries. Technical success with no procedural complications was seen in all cases. Two patients died due to coexisting injuries on 29th and 43rd days of hospitalization. Median hospitalization period was 6.0 days (range: 1-43 days) and mean intensive care unit hospitalization was 7.7 days (range: 0-43 days). CONCLUSION: In our experience, endovascular treatment was a safe and effective option for acute traumatic peripheral and visceral arterial lesions.

ABSTRACT

We describe a complex congenital pelvic AVM with multiple feeding arteries arising from the side branches of the right internal iliac artery and a single draining vein in a male patient. Concomitant transarterial and transvenous embolization with a new liquid embolic agent Squid-12 and metallic coils enabled a complete embolization at a single session. Squid-12 is composed of ethylene vinyl alcohol copolymers and its lower viscosity makes it a promising agent for the treatment of AVMs. The patient showed prompt resolution of the symptoms and complete devascularization of the AVM lesion was persisted on the 1-month control angiography. The patient was asymptomatic on the 6th month follow-up.

ABSTRACT

PURPOSE: We aimed to present our preliminary single-center experience of the endovascular management of thoracic and abdominal aortic ruptures. MATERIALS AND METHODS: Between September 2010 and May 2012, 11 consecutive patients (nine males, two females; age range, 26-80 years) with thoracic and abdominal aortic ruptures underwent endovascular repair in our unit. Thoracoabdominal computed tomography (CT) angiography was performed for diagnosis and follow-up. Patients were selected for endovascular repair by a cardiovascular surgeon, anesthesiologist, and interventional radiologist. All repairs were performed using commercially available stent-grafts. The patients were followed up with CT angiography before discharge, at six months, and yearly thereafter. RESULTS: Three patients died by day 30. One patient died due to an unsuccessful procedure and hemodynamic instability; two patients died because of comorbidities. The other eight patients were followed for six to 24 months after the procedure. No endoleaks or late ruptures were observed during the follow-up period. The patient with iatrogenic thoracic aortic rupture developed paraplegia after the procedure. CONCLUSION: Reduced mortality due to aortic rupture has been reported with the expanding use of endovascular repair. Reports of small centers are important because of the rarity of these pathologies, and because transferring patients with aortic rupture to a referral center is not usually possible.
