OBJECTIVE: Surgical treatment of ventrally located intradural cysts is difficult and controversial. Laminectomy with division of the denticulate ligaments and gentle cord mobilization remains the standard approach, but risks further neurological deterioration secondary to cord manipulation. Our purpose is to evaluate the safety and effectiveness of a midline cord splitting approach as an alternative for treating ventral thoracic intradural cysts. METHODS: We describe two patients who were treated for ventral intradural cysts causing progressive and severe myelopathy...

Described by Kato et al1 , the frozen elephant technique (FET) has simplified aortic arch surgery. As with thoracic endovascular aortic repair (TEVAR), FET reconstructions often require re-intervention. Skilled endovascular management of FET complications is imperative as novel devices emerge. We describe two cases of early intervention for severe foreshortening and incomplete expansion of the Thoraflex TM (Vascutek, Inchinnan, UK) stent-graft.

BACKGROUND: Conjoined twinning is a rare congenital malformation, and the resultant huge body wall defects after separation of conjoined twins represent a real challenge to surgeons. METHODS: From 2004 to 2009, authors performed body wall reconstruction for 2 pairs of thoraco-omphalopagus twins and 1 pair of ischiopagus tetrapus twins. Before separation, the techniques of tissue expansion and tractive training were adopted to acquire sufficient skin for final coverage...

Aortic root aneurysm is the most common cardiovascular manifestation requiring surgical intervention in patients with Marfan syndrome (MFS), a heritable thoracic aortic disease. Elective replacement of the aortic root is the treatment of choice for patients with aneurysmal complications of the aortic root and ascending aorta. There are two basic approaches to aortic root replacement: valve-sparing (VS) and valve-replacing (VR) techniques. After successful aortic root replacement surgery, several patients with MFS may develop a late complication related to their aortic disease process, such as developing a pseudoaneurysm of the coronary artery reattachment buttons, aneurysmal expansion, or aortic dissection in the remaining native aorta...

Carol C Hasler
Early-onset scoliosis (EOS) describes a wide array of diagnoses and deformities exposed to growth. This potentially life-threatening condition is still 1 of the biggest challenges in pediatric orthopaedics. The enlightenment of Bob Campbell's thoracic insufficiency syndrome concept and the negative impact of the earlier short and straight spine fusion approach on respiratory function and survival have fueled the evolution of EOS care. Despite all the progress made, growth-friendly spine surgery remains to be a burden to patients and caregivers...

BACKGROUND: We sought to identify the trends in bilateral internal thoracic artery use and determine the degree to which the survival advantage of bilateral internal thoracic artery revascularization persists among perceived "high-risk" patients, compared with the use of left internal thoracic artery alone. METHODS: A retrospective review was conducted of patients who underwent isolated coronary artery bypass grafting for multivessel coronary artery disease at the Mayo Clinic between January 2000 and December 2015...

OBJECTIVE: Aortic dissection (AD) often involves the infrarenal aorta. We review our experience with open infrarenal aortic repair with or without false lumen intentional placement (FLIP) of endografts in the proximal dissected aorta as part of a hybrid strategy to treat complex AD. METHODS: A prospectively maintained database of patients undergoing intervention for AD was reviewed. Data regarding diagnosis, imaging features, nature of the infrarenal repair (one- vs two-stage procedure), endoleaks, need for additional interventions, morbidity, and mortality were collected...

PURPOSE: Stabilizing techniques for flail chest injuries are described through wide surgical approaches to the chest wall, especially in the most affected posterior and lateral regions. Severe morbidity due to these invasive approaches needs to be considered due to dissection of the scapular guiding muscles and the risk of injuries to neurovascular bundles. This study discusses possibilities for minimized approaches to the posterior and lateral regions. METHOD: Ten fresh-frozen cadavers in lateral decubitus position were observed on both sides...

OBJECTIVE: Distal stent graft-induced new entry (SINE) can occur after thoracic endovascular aortic repair (TEVAR) of type B aortic dissection. This study investigated the mechanism of distal SINE and its prevention using a restrictive bare stent (RBS) technique. METHODS: From January 2013 to December 2014, 68 consecutive type B aortic dissection patients received endovascular repair at our center. The RBS technique was used with distal oversizing (between the diameter of the thoracic stent graft and the descending aorta true lumen diameter at the level of the intended distal edge of the thoracic stent graft) >20%...

We describe the management of posterior trachea tears after blunt neck trauma in two children. The first, a 5 year-old boy who fell off his scooter, causing a 1.0cm tear in the membranous cervical trachea, was managed conservatively with 5 days of intubation. The second, a 12 year-old girl who fell on her bicycle, causing a 4.0cm tear in the membranous thoracic trachea, was repaired with thoracoscopic techniques. The presumed mechanism may be expansion of the U-shaped cartilage with tear of the membranous trachea...

The strategy of root reconstruction for Stanford type A aortic dissection (AAD) includes resection of the intimal tear site, correction of concomitant aortic valve dysfunction and amendment of coronary lesion. Supracommissural tube graft replacement is a well-adopted and convenient procedure for most patients, although its application is limited when distinct sinus expansion and severe intimal damage is present. Composite valve conduit replacement (Bentall procedure) is suitable for patients with overt sinus damage...

Laparoscopic transhiatal esophagectomy is a minimally invasive approach for esophageal cancer. However, a transhiatal procedure has not yet been established for en bloc mediastinal dissection. The purpose of this study was to present our novel procedure, hand-assisted laparoscopic transhiatal esophagectomy, with a systematic procedure for en bloc mediastinal dissection. The perioperative outcomes of patients who underwent this procedure were retrospectively analyzed. Transhiatal subtotal mobilization of the thoracic esophagus with en bloc lymph node dissection distally from the carina was performed according to a standardized procedure using a hand-assisted laparoscopic technique, in which the operator used a long sealing device under appropriate expansion of the operative field by hand assistance and long retractors...

BACKGROUND: Provisional Extension To Induce Complete Attachment (PETTICOAT) technique has shown good results in the treatment of acute type B aortic dissections (ABAD). Usually, uncovered tubular stainless steel stents are used to promote distal true lumen reattachment. METHODS: We describe the Petticoat technique using a conic self-expanding nitinol device as distal uncovered stent in five cases of complicated ABAD. We used as distal uncovered stent the single-flared E-XL (Jotec-GmbH)...

BACKGROUND: The quantification of extracellular volume fraction (ECV) by Cardiac Computed Tomography (CCT) can identify changes in the myocardial interstitium due to fibrosis or infiltration. Current methodologies require laboratory blood hematocrit (Hct) measurement - which complicates the technique. The attenuation of blood (HUblood ) is known to change with anemia. We hypothesized that the relationship between Hct and HUblood could be calibrated to rapidly generate a synthetic ECV without formally measuring Hct...

BACKGROUND: Uncontrollable chest wall bleeding secondary to thoracic trauma has been a challenging problem faced by surgeons. Thoracic packing has been described as a good alternative although most thoracic surgeons avoid it because of the potential deleterious effects on cardiopulmonary function. METHODS: We describe a selective gauze packing technique of the thoracic wall preserving cardiopulmonary function in 3 patients with uncontrollable bleeding, where gauze packs were placed on bleeding areas holding them in a "sandwich-like" arrangement between the skin and the pleura and tightly fixed with coated wire stitches using internal and external-thoracic Ventrofil® devices...

The size of the thoracodorsal artery perforator (TDAP) flap or pedicle, in general, may be found to be inadequate. Pre-expansion of the flap before harvest can be a solution to increase the size of the TDAP flap in such instances. The pre-expanded TDAP flap can be used to reconstruct large-sized defects with the advantage of primary closure of the donor site. This article presents details on the surgical technique and provides discussion of the authors' experiences.

This article introduces pre-expanded super-thin intercostal perforator flaps, particularly the flap that has a perforator from the first to second intercostal spaces. The key techniques, advantages and disadvantages, and complications and management of this flap are described. At present, the thinnest possible flap is achieved by thinning the pre-expanded flap that has a perforator from the first to second intercostal spaces. It is used to reconstruct large defects on the face and neck, thus restoring function and cosmetic appearance...
