Study Aim. Evaluation of results in blunt injury of the thoracic aorta (BAI) endovascular treatment.Materials and Methods. Sixteen patients were treated for BAI. Thirteen patients had associated polytrauma, 4 of these had a serious hypotensive status and 4 had an hemothorax. In the remaining 3, two had a post-traumatic false aneurysm of the isthmus and 1 had a segmental dissection. In those 13 patients a periaortic hematoma was associated to hemothorax in 4. All patients were submitted to an endovascular treatment, in two cases the subclavian artery ostium was intentionally covered.Results. One patient died for disseminated intravascular coagulation. No paraplegia was recorded. No ischemic complications were observed. A type I endoleak was treated by an adjunctive cuff. During the followup (1–9 years) 3 patients were lost. A good patency and no endoleaks were observed in all cases. One infolding and 1 migration of the endografts were corrected by an adjunctive cuff.Conclusion. The medium and long term results of the endovascular treatment of BAI are encouraging with a low incidence rate of mortality and complications. More suitable endo-suite and endografts could be a crucial point for the further improvement of these results.

Background Replacement of the descending thoracic aorta is traditionally performed via a left thoracotomy. Endovascular treatment of descending thoracic aortic aneurysms has recently evolved as an alternative treatment for selected patients, yet no long-term results are available. The authors replaced the descending thoracic aorta in a group of pigs with an interposition Dacron graft using a closed-chest, totally robotic technique. Methods Ten pigs, weighing 25 to 45 kg, underwent surgery using the DaVinci robotic surgical system. Under single-lung ventilation and CO2 insufflation, the descending thoracic aorta was completely mobilized. Proximal and distal cross-clamps were applied through separate accessory stab wounds. The mid-descending thoracic aorta was excised. An interposition Dacron graft was robotically sewn in an end-to-end fashion to the descending thoracic aorta using interrupted nitinol clips. Results All animals survived the procedure. Mean aortic clamp time was 55 ± 14 minutes. All anastomoses were completed without difficulty with a mean total anastomotic time of 42 ± 11 minutes. The anastomoses were challenged for bleeding by administrating α1-adrenergic receptor agonists to a systolic blood pressure of 200 mm Hg with no evidence of leak. Discussion Robotic replacement of the thoracic aorta is feasible and reproducible. This procedure provides the standard Dacron graft repair with its known long-term results. The added value of robotic technology to the therapeutic armamentarium in the treatment of thoracic aortic aneurysms may be worth the effort required for procedural development. Furthermore, it may serve as a valid alternative to endovascular treatment of thoracic aortic aneurysms.

Purpose: To assess the long-term results of a homemade aortomonoiliac polytetrafluoroethylene (PTFE) device used for endovascular abdominal aortic aneurysm (AAA) repair. Methods: A vascular audit database was interrogated to identify 58 consecutive AAA patients (all men; median age 73 years, range 56–88) who underwent aortomonoiliac stent-graft repair. AAAs were eligible for endovascular treatment if the infrarenal neck was ≥15 mm long and ≤28 mm in diameter. Results: Nine (15.5%) procedures failed, 8 during the procedure and 1 on the 7th postoperative day; 8(13.8%) patients were converted, but one was unfit for surgery. There was one intraprocedural stroke, and 3 (5.2%) patients died within 30 days. The primary success rate (no conversion or mortality) was 79.3%. Over a median follow-up of 45 months (range 23–80), there were 3 (5.2%) graft occlusions, 1 kink requiring stent implantation, and 1 expanding sac without identifiable endoleak. There were 11 (19.0%) endoleaks in 10 patients, 9 type I leaks (2 proximal) and 1 type II. One patient with a distal type I endoleak (treated) also exhibited a type III leak at 2 years, but the sac size had not increased. There was a 40% incidence of bilateral buttock claudication, which was serious in only 1 patient. The long-term survival rate by Kaplan-Meier life-table analysis was 57% at 4 years. Conclusions: Implantation of an aortomonoiliac PTFE device can be achieved with good primary success, and the stent-graft seems durable over the long term. Proximal type I endoleaks are rare, but distal endoleaks from the contralateral common iliac artery can be solved by using a different covered stent.

Objective – to evaluate long-term results of treatment of patients with arteriovenous malformations AVM of the spinal cord. Materials and methods. A retrospective analysis of clinical and angiographic data of the results of treatment of patients with spinal AVM for the period from 2005 to 2019 was conducted. In SO «Scientific-Practical Center of Endovascular Neuroradiology NAMS of Ukraine» 47 patients were operated on endovascular method. The age of patients ranged from 11 to 62 years (middle age is 45.3 years). There were 29 men (61.7 %), 18 women (38.3 %). Liquid cyanoacrylate embolizant was used for endovascular intervention. The operations were performed with transfemoral access. Accoding the classification proposed by Anson and Spetzler in 1992 patients with type I were 31 (65.9 %), with ІІ type – 8 (17.0 %), with ІIІ type – 5 (10.6 %), with IV type – 3 (6.4 %). Magnetic resonance tomography and spinal angiography were used for diagnostics AVM.Results. Total exclusion of AVM from the bloodstream was achieved in 22 (46.8 %) cases. Out of the 31 (65.9 %) patients with type I AVM, 17 (54.8 %) had an early transient deepening of the neurological deficit. In this group, complete dissection of arteriovenous fistula was achieved in 16 (51.6 %) patients. In 8 (17.0 %) patients with type II AVM, complete exclusion of AVM was achieved in 5 (62.5 %) cases. In this case, 6 (75.0 %) patients were observed early postoperative deepening of neurological symptoms. In 5 (10.6 %) patients with type III AVM, total exclusion was achieved in 1 (20.0 %) case. Transient deepening of neurological deficit was noted in 3 (60.0 %) patients. In 3 (75.0 %) patients with type IV AVM, total embolization was achieved in 1 (33.0 %) observation. Neurological impairment occurred in 1 (33.0 %) patient. In all groups there were no fatalities.Conclusions. Angiography is the gold standard of diagnosis and dynamic monitoring of patients with spinal cord AVM. The use of endovascular treatment of AVM can stop the further progression of neurological deficits, which, however, is not always associated with the total exclusion of AVM. The best neurological improvement and total exclusion were achieved in patients with type I AVM. Radicality, efficacy and deepening of neurological deficiency depend on angioarchitectonics of AVM. The main condition for carrying out embolization is to achieve a safe level of catheterization of the afferent.

INTRODUCTION Interest for traumatic thoracic aorta rupture stems from the fact that its number continually increases, and it can be rapidly lethal. OBJECTIVE The aim of this study is to present early and long term results as well as experiences of our team in surgical treatment of traumatic thoracic aorta rupture. METHOD Our retrospective study includes 12 patients with traumatic thoracic aorta rupture treated between 1985 and 2007. There were 10 male and two female patients of average age 30.75 years (18-74). RESULTS In six cases, primary diagnosis was established during the first seven days days after trauma, while in 6 more than one month later. In 11 cases, classical open surgical procedure was performed, while endovascular treatment was used in one patient. Three (25%) patients died, while two (16.6%) had paraplegia. Nine patients (75%) were treated without complications, and are in good condition after a mean follow-up period of 9.7 years (from one month to 22 years). CONCLUSION Surgical treatment requires spinal cord protection to prevent paraplegia, using cardiopulmonary by-pass (three of our cases) or external heparin-bonded shunts (five of our cases). Cardiopulmonary by-pass is followed with lower incidence of paraplegia, however it is not such a good solution for patients with polytrauma because of hemorrhage. The endovascular repair is a safe and feasible procedure in the acute phase, especially because of traumatic shock and polytrauma which contributes to higher mortality rate after open surgery. On the other hand, in chronic postrauamatic aortic rupture, open surgical treatment is connected with a lower mortality rate and good long-term results. There have been no published data about long-term results of endovascular treatment in the chronic phase.

Abstract BACKGROUND: The clinical significance of pathologies of the spinal dura is often unclear and their management controversial. OBJECTIVE: To classify spinal dural pathologies analogous to vascular aneurysms, present their symptoms and surgical results. METHODS: Among 1519 patients with spinal space-occupying lesions, 66 patients demonstrated dural pathologies. Neuroradiological and surgical features were reviewed and clinical data analyzed. RESULTS: Saccular dural diverticula (type I, n = 28) caused by defects of both dural layers, dissections between dural layers (type II, n = 29) due to defects of the inner layer, and dural ectasias (type III, n = 9) related to structural changes of the dura were distinguished. For all types, symptoms consisted of local pain followed by signs of radiculopathy or myelopathy, while one patient with dural ectasia presented a low-pressure syndrome and 10 patients with dural dissections additional spinal cord herniation. Type I and type II pathologies required occlusion of their dural defects via extradural (type I) or intradural (type II) approaches. For type III pathologies of the dural sac no surgery was recommended. Favorable results were obtained in all 14 patients with type I and 13 of 15 patients with type II pathologies undergoing surgery. CONCLUSION: The majority of dural pathologies involving root sleeves remain asymptomatic, while those of the dural sac commonly lead to pain and neurological symptoms. Type I and type II pathologies were treated with good long-term results occluding their dural defects, while ectasias of the dural sac (type III) were managed conservatively.

Anterior Palatoplasty

OBJECTIVE: Review long-term results of the modified cautery-assisted palatoplasty (mod CAPSO)/anterior palatoplasty for the treatment of mild-moderate obstructive sleep apnea (OSA). STUDY DESIGN: Prospective series of 77 patients. All patients were >18 years old, type I Fujita, body mass index (BMI) < 33, Friedman clinical stage II, with apnea-hypopnea index (AHI) from 1.0 to 30.0. The mean follow-up time was 33.5 months. The procedure involved an anterior soft palatal advancement technique with or without removal of the tonsils. The procedure was done under general or local anesthesia. RESULTS: There were 69 men and eight women; the mean age was 39.3 years old; and mean BMI was 24.9 (range 20.7–26.8). There were 38 snorers and 39 OSA patients. The AHI improved in patients with OSA, 25.3 ± 12.6 to 11.0 ± 9.9 ( P < 0.05). The overall success rate for this OSA group was 71.8 percent (at mean 33.5 months). The mean snore scores (visual analog score) improved from 8.4 to 2.5 (for all 77 patients). Lowest oxygen saturation also improved in all OSA patients. Subjectively, all patients felt less tired. CONCLUSION: This technique has been shown to be effective in the management of patients with snoring and mild-moderate OSA.
