RESUMO
BACKGROUND: Venous congestion after deep inferior epigastric artery perforator (DIEP) flap breast reconstruction is a complication that may be partially attributable to variations in venous abdominal wall anatomy. In previous work, we have shown that ferumoxytol may be used as a bloodpool contrast agent to perform high-resolution venous imaging. Our current aim was to use this technology to perform a detailed analysis of the venous anatomy among patients undergoing DIEP flap breast reconstruction. METHODS: All patients undergoing DIEP flap reconstruction with preoperative ferumoxytol-enhanced magnetic resonance angiography (FE-MRA) were retrospectively reviewed. A detailed anatomic analysis of each abdominal wall on FE-MRAwas performed before review of operative findings. Statistical analysis was used to determine venous characteristics associated with superficial inferior epigastric vein (SIEV) augmentation. RESULTS: From 2012 to 2016, 59 patients underwent preoperative FE-MRA. This resulted in imaging for 118 hemiabdomen and 99 flaps. Superficial-deep communication was identified in 117 of 118 hemiabdomen. Fifty (93%) of 59 patients had greater than 1-mm venous communication of the superficial system across midline. Reconstructed breasts were based on dominant medial row perforators in 82 (83%) of 99 flaps. The mean diameters of the SIEVand dominant venous perforator were 3.8 and 2.8mm, respectively. Anatomic characteristics associated with SIEVaugmentation included SIEVdiameter ( P = 0.01), dominant perforator diameter ( P = 0.04), and the ratio between these 2 variables ( P = 0.001). CONCLUSIONS: Ferumoxytol-enhanced magnetic resonance angiography provides excellent imaging of the venous system. Anatomic characteristics such as the diameter of the SIEVand the diameter of the dominant perforator may be useful in determining which flaps require venous augmentation using the SIEV.

BACKGROUND: Breast cancer patients with ptotic breasts pursuing mastectomy with immediate reconstruction can present challenges. A wise pattern (inverted-T) mastectomy incision (WPM) has been suggested as an alternative to the standard horizontal elliptical mastectomy (EM) to reduce redundant skin and correct ptosis. Herein, we sought to examine the differences in morbidity between the two techniques. METHODS: We performed a retrospective review of women undergoing mastectomy with immediate reconstruction at our institution from June 2007 to January 2016. We compared those undergoing WPM to a control population undergoing EM. Statistical analysis was performed evaluating clinical, pathological, and surgical outcome variables according to patient and per breast. All tests were two-sided with alpha level set at 0.05 for statistical significance. RESULTS: A total of 241 women underwent mastectomy and reconstruction in 421 breasts; 78/241 (32%) had WPM (149 breasts), 163/241 (68%) had EM (272 breasts). Both groups were similar in age, smoking status, diabetes, race, tumor type, and pathologic stage (all P > 0.07). Skin flap necrosis was the most frequently encountered complication, occurring in 58/149 (38.9%) of WPM breasts and in 24/272 (8.9%) of EM breasts (P < 0.0001). There was no difference in the need for revisional procedures between the groups (WPM: 24.1% vs EM: 17.6%, P = 0.207). CONCLUSION: Patients should be counseled WPM is associated with higher rates of skin flap necrosis. However, this does not translate into higher rates of revisional procedures or return to OR.

Perioperative hyperglycemia is a well-known risk factor for surgical morbidity such as wound healing, infection, and prolonged hospitalization. This association has been reported for a number of surgical subspecialties, including plastic surgery. Specialty-specific guidelines have become increasingly available in the literature. Currently, glucose management guidelines for plastic surgery are lacking. Recognizing that multiple approaches exist for perioperative glucose, protocol-based models provide the necessary structure and guidance for approaching glycemic control. In this article, we review the influence of diabetes on outcomes in plastic surgery patients and propose a practical approach to perioperative blood glucose management based on current Endocrine Society and Mayo Clinic institutional guidelines.

BACKGROUND: Long-term follow-up of patients with aortouniiliac (AUI) grafts is lacking in the current literature. The purpose of this study was to review the outcomes of endovascular aneurysm repair (EVAR) using commercially available AUI devices with femorofemoral bypass in patients whose aortoiliac anatomy was unfavorable for bifurcated repair. METHODS: A retrospective review of 35 patients from September 2000 to February 2012, who underwent EVAR with commercially manufactured AUI devices, was performed. These comprised 35 of 372 (9.4%) patients who underwent EVAR during that period. Patient records were reviewed to determine morbidity, mortality, and survival after AUI repair. Patients were followed at 1-, 3-, 6-, and 12-month intervals with computed tomography (CT) scans during each visit. Median follow-up was 40 months (range: 2-135 months). RESULTS: Median age at surgery was 76 years (range: 60-93). The median preoperative aneurysm diameter was 57 mm (range: 45-71) and the median postoperative diameter was 53 mm (range: 29-80). Two type II endoleaks occurred on 1-month CT, whereas 10 endoleaks (type I [3], II [6], and III [1]) occurred during follow-up after 1 month. Migration of the stent graft occurred in 9% (n=3). Secondary procedures were required in 26% (n=9), whereas tertiary procedures were required in 3% (n=1). One patient required treatment for thrombosis of the iliac extension and 2 required treatment for thrombosis of the femorofemoral component. Mortality over the follow-up period was 34% (n=12) with no deaths occurring within 30 days. CONCLUSIONS: High-risk patients who present with aortoiliac anatomy unsuitable for bifurcated stent graft placement should be offered AUI graft placement as a potential alternative to open repair.

BACKGROUND: Given the malignant potential of main duct intraductal papillary mucinous neoplasm (M-IPMN), surgical resection is generally indicated. With regard to side-branch intraductal papillary mucinous neoplasm (SB-IPMN), resection vs. observation is a topic of debate. Further review of SB-IPMN is necessary to clarify appropriate management. The primary focus of this project is to determine the incidence of malignant final pathology for patients undergoing surgery for isolated SB-IPMN with non-malignant fine-needle aspiration (FNA) cytology. We also sought to describe the relationship between factors considered in the international consensus guidelines and final pathologic outcome. METHODS: The study is a retrospective review of all patients who underwent surgical resection for intraductal papillary mucinous neoplasm (IPMN) from 2002 to 2013 at our institution. Patients with a preoperative diagnosis of isolated SB-IPMN and FNA results for non-malignant cytology were selected among this surgical cohort for further analysis of preoperative clinical characteristics and outcomes. RESULTS: A total of 137 patients undergoing resection for IPMN were identified. Of these, 81 patients (59%) had a component of M-IPMN or invasive disease on FNA, leaving 66 (46%) patients with SB-IPMN and non-malignant cytology. Invasive adenocarcinoma was found in 8/66 (12%) patients and high-grade dysplasia (HGD) in 4/66 (8%) patients. The mean [SD] diameter of benign SB-IPMN was 2.0 cm [1.1] (range 0.3-5.7) vs. that of HGD/invasive disease which was 3.1 cm [1.3] (range 1.5-6.0; P = 0.014). Of the 12 patients found to have HGD or invasive disease, symptoms, mural nodules, and septations were found in 7 (58%), 5 (42%), and 6 (50%), respectively. Tumor staging were as follows: IA (2), IB (2), 2A (4), and 2B (1). CONCLUSION: With proper selection criteria, SB-IPMN is associated with a low rate of invasive pancreatic ductal adenocarcinoma at the time of resection. Nevertheless, given the demonstrated incidence of malignancy, appropriate operative candidates should undergo resection.

INTRODUCTION: Cervical thoracic duct cyst (CTDC) is a rare cause of lateral neck mass. Surgical excision with ligation of the cervical thoracic duct is the current standard for definitive management with symptomatic patients. We report the first case of an alternative method of management performing a cyst venous anastomosis for decompression. PRESENTATION OF CASE: A 77 year old female presented with a six month history of left arm pain, swelling and a left-sided cystic neck mass. She was treated with cyst-venous anastomosis between the cyst wall and the left internal jugular vein. At two year follow-up, she has had resolution of pain and no recurrence of the mass. DISCUSSION: Many potential etiologies have been proposed for CTDC, though surgical management of this rare problem has consistently required cyst excision and thoracic duct ligation. Few innovative modes of therapy have been developed to address this problem in a less invasive manor. Maintaining a more natural thoracic duct anatomy decreases the likely of complications associated with duct ligation. CONCLUSION: Cyst-venous anastomosis for the management of CTDC provides an effective, novel form of treatment which maintains the integrity of the thoracic duct and avoids potential complications associated with duct ligation.
RESUMO
OBJECTIVE: Subarachnoid hemorrhage (SAH) is a particularly devastating type of stroke which is responsible for one third of all stroke-related years of potential life lost before age 65. Surgical treatment has been shown to decrease both morbidity and mortality after subarachnoid hemorrhage. We hypothesized that payer status other than private insurance is associated with lower allocation to surgical treatment for patients with SAH and worse outcomes. DESIGN: We examined the association between insurance type and surgical treatment allocation and outcomes for patients with SAH while adjusting for a wide range of patient and hospital factors. We analyzed the Nationwide Inpatient Sample hospital discharge database using survey procedures to produce weighted estimates representative of the United States population. PATIENTS: We studied 21047 discharges, representing a weighted estimate of 102595 patients age 18 and above with a discharge diagnosis of SAH between 2003 and 2008. MEASUREMENTS: Multivariable logistic and generalized linear regression analyses were used to assess for any associations between insurance status and surgery allocation and outcomes. MAIN RESULTS: Despite the benefits of surgery 66% of SAH patients did not undergo surgical treatment to prevent rebleeding. Mortality was more than twice as likely for patients with no surgical treatment compared to those who received surgery. Medicare patients were significantly less likely to receive surgical treatment. CONCLUSIONS: Nearly two thirds of patients with SAH don't receive operative care, and Medicare patients were significantly less likely to receive surgical treatment than other patients. Bias against the elderly and those with chronic illness and disability may play a part in these findings. A system of regionalized care for patients presenting with SAH may reduce disparities and improve appropriate allocation to surgical care and deserves prospective study.
