Pseudoaneurysm at the suture line is one of the most common complications in aortic surgery for Takayasu arteritis (TA) and is associated with a high mortality rate. A 52-year-old man with TA, who previously underwent the Bentall procedure and two redo surgeries for coronary artery obstruction and a pseudoaneurysm of a coronary button, was diagnosed with an anastomotic pseudoaneurysm in the ascending aorta. Hybrid zone 0 debranching thoracic endovascular aortic repair was performed, and the patient was discharged uneventfully on postoperative day 8...

Despite recent publications indicating billowing (aneurysmal degeneration of the outer fabric material manifesting as a bulging sac of contained contrast due to weakening of the fabric material between the metal struts) as a benign finding, we present a unique case of billowing that resulted in aneurysmal rupture with the AFX2® stent-graft (Endologix, Inc., Irvine, CA). AFX2® consists of an inner metallic endoskeleton with multiple metallic struts covered by a polytetrafluoroethylene graft fabric (PTFE). It allows for the flow of blood or contrast beyond the border of the metallic endoskeleton without evidence of endoleak or rupture secondary to the outer cover being anchored to the endoskeleton with polypropylene sutures only at the proximal and distal ends...

In this paper we investigate the feasibility of harvesting energy from cardiac valvular perturbations to self-power a wireless sonomicrometry sensor. Compared to the previous studies involving piezoelectric patches or encasings attached to the cardiac or aortic surface, the proposed study explores the use of piezoelectric sutures that can be implanted in proximity to the valvular regions, where non-linear valvular perturbations could be exploited for self-powering. Using an ovine animal model, the magnitude of valvular perturbations are first measured using an array of sonomicrometry crystals implanted around the tricuspid valve...

We investigated the influence of mechanical stretching on the genetic expression pattern of noncollagenous bone matrix proteins in osteoblasts. The cranial sutures of neonatal mice were subjected to ex vivo mechanical stretching. In the nonstretched control group, as osteoblast differentiation progressed, the successive genetic expression of bone sialoprotein (BSP), osteopontin (OPN), and osteocalcin (OCN) was detected using in situ hybridization, in that order. In the stretched group, the sutures were widened, and after 24 hr of cultivation, a large number of osteoblasts and abundant new osteoid were observed on the borders of the parietal bones...

Several operative techniques for inframammary fold (IMF) reconstruction have been described and have resolved the shortcomings of conventional methods. However, there are still difficulties with IMF reconstruction, that is, performance through small mastectomy scars, creation of a smooth IMF curve, transfer of external IMF markings to the interior chest wall, or determining correct IMF without an implant in place. We have used a type of anchor suture with a completely percutaneous approach, the vertical pendulum suture (VP suture), to reconstruct the IMF easily in implant-based breast reconstruction...

The position of the nasal tip holds important aesthetic significance. Cephalic rotation of the nasal tip is a frequent motivating factor for patients seeking rhinoplasty. The position of the nasal tip is a complex interplay of the size, morphology, and position of several anatomic components of the lower one-third of the nose. Cephalic rotation can be achieved by way of six different methods. The indirect methods promote passive cephalic rotation and include cephalic trim of the lower lateral cartilages, caudal trim of the upper lateral cartilages, and caudal septal trim...

BACKGROUND: Our previous study showed that muscle-derived cells could regenerate strong engineered tendon with better tissue structure. However, little was known about the mechanism of neo-tendon built by muscle-derived cells, and the development and maturation of the cells. We hypothesized that mechanical loading modulated this process. The aim of this study is to investigate whether mechanical loading could regulate muscle-derived cells engineered tendon formation and maturation. METHODS: Muscle-derived cells were isolated, expanded and seeded on polyglycolic acid (PGA) fibers that formed a cell-scaffold complex...

In 1986, Altemir first reported the use of submental intubation to avoid tracheotomy in patients with panfacial and midfacial fractures for whom intermaxillary fixation is necessary, but orotracheal and nasotracheal intubations are not recommended. This novel technique allowed intraoperative access to perform dental occlusion and reconstruction of the nasal pyramid in patients with skull base fractures. Herein, we describe a refined technique based on Altemir's original procedure. Seven male patients with panfacial fractures underwent submental intubation using our refined technique...

The transverse colon is a particularly rare site for a diverticulum to develop, with only few reports of solitary diverticula described in the literature. Among the reported complications, colocutaneous fistulas appear relatively infrequently. We describe the case of an 80-year-old woman with a solitary diverticulum of the transverse colon presenting as acute diverticulitis with abscess formation in the epigastric region. A fistulous tract was found between the inflamed colon and the skin. A wedge resection of the inflamed colon together with the fistula and the solitary diverticulum was performed followed by primary suturing of the healthy colonic tissue...

Introduction: Microsurgery is a subspecialised field which requires high technical skill. Laboratory training offers good opportunity for novice surgeons to learn and repetitively practise their skills prior to hands-on clinical practice. Commonly, the training programme consists of models in a stepwise increase in fidelity: from latex sheet to anaesthetised rat. We introduce microgrids model as a daily warm up procedure in a 5-day basic microsurgery course. The purpose of this study is to evaluate the correlation between microgrids colouring under magnification with microsuturing proficiency among novice surgeons...

Introduction: The optimal surgical treatment for acromioclavicular joint (ACJ) injuries remains controversial. The modified Weaver-Dunn (WD) procedure is one of the frequently used techniques. Recently when it was compared with anatomical autogenous tendon graft reconstruction procedures, the results were inferior. However, these anatomical procedures are technically more demanding with small margin of error and they have tendency for postoperative pain because of extra donor site incision. Materials and Methods: Forty patients with type IV to VI ACJ dislocations were treated by modified WD procedure using non-absorbable synthetic suture passed through the base of coracoid process for augmentation of transferred coraco-acromial (CA) ligament...

A 68-year-old man presented with a posterior tracheal wall injury caused by percutaneous dilatational tracheostomy. The wound was immediately covered with an absorbable polyglycolic acid sheet. Ten days after the injury, the perforation was closed with knotless sutures using a Castroviejo needle-holder through the tracheostomy. The successful repair in this case indicates the feasibility of the knotless suture technique for perforations. The technique is described in detail in this report. The patient was weaned from the mechanical ventilator on postoperative day 25...

Laparoscopic right colectomy by the rule of complete mesocolic excision is becoming a standard operation for right colon cancer. Intraoperative iatrogenic vascular injuries are rare but disastrous complications. In addition to the dissection along the embryonic plane, reducing iatrogenic bleeding is of crucial importance to safeguard the surgical procedure. Keeping the operative field clear by gentle suction to have a good exposure is essential to identify the origin of bleeding, and then to make decision how to control the bleeding by bipolar coagulation, clipping and transection, suturing or conversion to open surgery...
