AbstractIntroductionDespite advances in trauma care, hemorrhage continues to be the leading cause of preventable mortality in trauma. The evidence to support its use in non‐trauma patients is limited. We aim to report our experience with prehospital blood product transfusion. We hypothesize that it is safe, appropriately utilized, and that our protocol, which was designed for trauma patients, is adaptable to fit the needs of non‐trauma patients.MethodsPatients transfused with blood products, packed red blood cells (pRBCs) or plasma, in the prehospital environment between 2002 and 2014 were included. Trauma patients were compared to non‐trauma patients using descriptive statistics.ResultsA total of 857 patients (n = 549 trauma and n = 308 non‐trauma) were transfused with pRBCs (76 %, n = 654, mean 1.6 ± 1.1 units en route), plasma (53 %, n = 455, mean 1.7 ± 0.7 unit), or both (29 %, n = 252) during ground (12 %) or air (84 %) critical care transport. Mean age was 60.8 ± 21.6 years with 60.1 % (n = 515) males. Subsequently, in‐hospital blood transfusions were performed in 80 % of patients, operations in 44 %, and endoscopy in 31 %. Five percent (n = 41) of patients did not require any of these interventions. Thirty‐day mortality rate was 18 %, and one patient (<0.01 %) had a transfusion reaction. The majority of patients were non‐trauma (n = 549, 64 %). Of the non‐trauma patients, 219 (40 %) were surgical, 193 (35 %) gastrointestinal bleeds, and 137 (25 %) medical.ConclusionBoth non‐trauma and trauma patients require blood products for life threatening hemorrhage and the majority required further interventions. Further research on the benefits of transfusion among non‐trauma patients is warranted.

Background. Reconstruction of intrapelvic defects can be a challenging problem in patients with limited regional muscle flap options and previously resected omentum. In such situations, alternative methods of mobilizing vascularized tissue may be required.Methods. A case of a patient that underwent pelvic extirpation for recurrent rectal cancer who had limited donor sites for flap reconstruction is presented. The mucosa was removed from a blind loop of colon, and a pedicled seromuscular flap based on the colonic mesentery was placed into the pelvis for vascularized soft-tissue coverage and elimination of dead space.Results. The postoperative course was only complicated by a small subcutaneous fluid collection beneath the sacrectomy skin incision, which was drained with radiological assistance. The patient recovered without any major postoperative complications.Conclusion. Seromuscular colonic flap is a useful option for soft-tissue coverage after pelvic extirpation and should be considered by plastic surgeons when other reconstruction options are not available.

AbstractIntroductionAlthough seemingly straightforward, tube thoracostomy (TT) has been associated with complication rates as high as 30 %. A lack of a standardized nomenclature for reporting TT complications makes comparison and evaluation of reports impossible. We aim to develop a classification method in order to standardize the reporting of complications of TT and identify all reported complications of TT and time course in which they occurred to validate the reporting method.MethodsA systematic search of MEDLINE, Scopus, EMBASE, and Cochrane Central Register of Controlled Trials and Database of Systematic Reviews from each databases inception through November 5, 2013 was conducted. Original articles written in the English language reporting TT complications were searched. This review adhered to preferred reporting items for systematic reviews and meta‐analyses (PRISMA) standards. Duplicate reviewers abstracted case reports for inclusion. Cases were then sorted into one of the five complication categories by two reviewers, and in case of disagreements, settled by a third reviewer.ResultsOf 751 papers reporting TT complications, 124 case reports were included for analysis. From these reports, five main categories of TT complications were identified: insertional (n = 65); positional (n = 36); removal (n = 11); infective and immunologic (n = 7); and instructional, educational, or equipment related (n = 5). Placement of TT has occurred in nearly every soft tissue and vascular structure in the thoracic cavity and intra‐abdominal organs.ConclusionOur classification method provides further clarity and systematic standardization for reporting TT complications.

Endovascular repair has become the first line of treatment in most patients with blunt aortic injury. The most common mechanism is deceleration injury affecting the aortic isthmus distal to the origin of the left subclavian artery. Injuries of the distal thoracic aorta are uncommon. We report the case of a 25-year-old male patient who presented with paraplegia and distal thoracic aortic pseudoaneurysm associated with severe thoracolumbar vertebral fracture and displacement after a motocross accident. Endovascular repair was performed using total percutaneous technique and conformable C-TAG thoracic stent-graft (WL Gore, Flagstaff, AZ). Following stent-graft placement and angiographic confirmation of absence of endoleak, thoracolumbar spinal fixation was performed in the same operative procedure. This case illustrates a multispecialty approach to complex aortic and vertebral injury and the high conformability of newer thoracic stent-grafts to adapt to tortuous anatomy.

The resection of large pelvic tumors is challenging due to their infiltrative nature into multiple structures and organ systems. In this report, we describe the use of multiple vascularized and nonvascularized spare parts to reconstruct a pelvic defect in a patient with a uniquely large pelvic sarcoma invading the spinal canal. A 39‐year‐old Caucasian female who presented with a large retroperitoneal sarcoma where the tumor encased the left ureter, kidney, colon, and external iliac vessels and invaded the L3‐S1 vertebral bodies. An extensive hemipelvectomy and reconstruction was performed over two days. A free thigh and leg fillet flap together with ipsilateral fibula flap, based on the superficial femoral artery and venae comitantes, was used for spinal reinforcement as well as abdominal and pelvic wall reconstruction. The postoperative course was uneventful without complications, no flap compromise or wound healing problems. After a follow‐up period of 4 months, the patient had no complications and returned to activities of daily living with mild limitations. The success of this flap procedure shows the practicality and usefulness of using the full spectrum of tissue transfer for the purposes of a large pelvic reconstruction. © 2014 Wiley Periodicals, Inc.
