Aspetti Ultrasonografici in Corso di Sviluppo Placentare e Adattamento Cardiovascolare nella Cavalla Gravida: ecografia bidimensionale, ecocardiografia ed ecocontrastografia (CEUS)

In corso di gravidanza normale avvengono modificazioni emodinamiche centrali e periferiche volte a garantire le crescenti richieste nutritive dell'unità feto-placentare. L’ecografia con mezzo di contrasto (CEUS-Contrast Enhanced Ultrasonography) a base di microbolle offre una nuova opportunità di monitorare e quantificare la perfusione utero-placentare in condizioni normali e patologiche. L’ecocardiografia è stata ampiamente usata in medicina umana per valutare l’adattamento morfo-funzionale cardiaco materno durante la gravidanza. Gli scopi di questo lavoro prospettico sono stati di applicare, per la prima volta nella specie equina, un mezzo di contrasto di II generazione (Sonovue®), al fine quantificare la perfusione utero-placentare in corso di gravidanza normale, valutandone gli effetti sul benessere materno-fetale e di descrivere le modificazioni nei parametri ecocardiografici morfometrici e funzionali cardiaci, in particolare relativi alla funzione del ventricolo sinistro nel corso di una gravidanza fisiologica. Due fattrici sane di razza Trottatore sono state monitorate ecograficamente in maniera seriale durante l’intero corso della gravidanza, tramite esame bidimensionale, ecocontrastografia dell'unità utero-placentare, flussimetria Doppler delle arterie uterine, ecocardiografia materna in modalità bidimensionale, M-mode, Doppler e Tissue Doppler Imaging. I neonati sono stati clinicamente monitorati e gli invogli fetali esaminati. Il pattern di microperfusione utero-placentare è valutabile quali-quantitativamente tramite la CEUS e dimostra un’aumento del flusso a livello di microvascolarizzazione uterina con l'avanzare della gravidanza; non è stata rilevata la presenza di microbolle a livello di strutture fetali nè effetti dannosi sul benessere materno-fetale. In questo studio sono state osservate delle modificazioni cardiache materne in corso di gravidanza fisiologica, relative all'aumento della FC, del CO ed in particolare all'aumento delle dimensioni dell'atrio sinistro ed a modificazioni nelle onde di velocità di flusso e tissutali di riempimento del ventricolo sinistro.

Minimal-invasive percutaneous reduction and transsacral screw fixation for U-shaped fractures

STUDY DESIGN Technical note and case series. OBJECTIVE To introduce an innovative minimal-invasive surgical procedure reducing surgery time and blood loss in management of U-shaped sacrum fractures. SUMMARY OF BACKGROUND Despite their seldom appearance, U-shaped fractures can cause severe neurological deficits and surgical management difficulties. According to the nature of the injury normally occurring in multi-injured patients after a fall from height, a jump, or road traffic accident, U-shaped fractures create a spinopelvic dissociation and hence are highly unstable. In the past, time-consuming open procedures like large posterior constructs or shortening osteotomies with or without decompression were the method of choice, sacrificing spinal mobility. Insufficient restoration of sacrococcygeal angle and pelvic incidence with conventional techniques may have adverse long-term effects in these patients. METHODS In a consecutive series of 3 patients, percutaneous reduction of the fracture with Schanz pins inserted in either the pedicles of L5 or the S1 body and the posterior superior iliac crest was achieved. The Schanz pins act as lever, allowing a good manipulation of the fracture. The reduction is secured by a temporary external fixator to permit optimal restoration of pelvic incidence and sacral kyphosis. Insertion of 2 transsacral screws allow fixation of the restored spinopelvic alignment. RESULTS Anatomic alignment of the sacrum was possible in each case. Surgery time ranged from 90 to 155 minutes and the blood loss was <50 mL in all 3 cases. Two patients had very good results in the long term regarding maintenance of pelvic incidence and sacrococcygeal angle. One patient with previous cauda equina decompression had loss of correction after 6 months. CONCLUSIONS Percutaneous reduction and transsacral screw fixation offers a less invasive method for treating U-shaped fractures. This can be advantageous in treatment of patients with multiple injuries.

Minimally invasive approach to lumbosacral decompression in a cadaveric canine model

AIMS To determine efficacy of a minimally invasive (MI) surgical approach using a human MI lumbar retractor for canine lumbosacral dorsal laminectomy and partial discectomy and to compare this technique to the standard open surgical (OS) approach. METHODS Lumbosacral dorsal laminectomy and partial discectomy was performed on 16 large-breed canine cadavers using either a standard OS (n=8) or MI (n=8) approach. Skin and fascial incision length, procedure time, and intraoperative complications were recorded. Postoperatively specimens were evaluated for laminectomy and discectomy dimensions, and visible damage to the cauda equina and exiting nerve roots. RESULTS Median length of skin and fascial incisions in the OS group were longer than in the MI group (p<0.001). Median laminectomy length was similar between both approaches (p=0.234) but width was greater for the MI than OS approach (p=0.002). Both approaches achieved similar partial discectomy width (p=0.279). Overall surgical time was longer for MI approaches compared to OS, with a median of 18.5 (min 15.5, max 21.8) minutes for MI compared to 14.6 (min 13.1, max 16.9) minutes for OS (p=0.001). CONCLUSIONS The MI approach reduced incision lengths while retaining comparable laminectomy and discectomy dimensions. For this in vitro model the MI approach required more time to complete, but this difference may not be relevant in clinical cases. CLINICAL RELEVANCE Dogs undergoing lumbosacral dorsal laminectomy are commonly large-breed dogs. The traditional open approach requires a large skin incision and soft tissue dissection, especially in overweight animals. A MI approach accomplishing the same surgical result while minimising soft tissue trauma could reduce post-operative pain and recovery time, and may lower wound-related complications. Clinical studies are needed to confirm postoperative benefit and assess operating times in vivo.
