A rare case of bilateral subclavian artery agenesis.

Arterial agenesis is a rare condition and has been reported to affect the internal carotid artery, common carotid artery, and pulmonary artery. However, to the best of our knowledge, it has not yet been reported to affect the subclavian arteries. We present a case of asymptomatic bilateral subclavian artery agenesis and left subclavian artery aneurysm. This patient's abnormal vasculature was found incidentally. Despite being asymptomatic, repair of the aneurysm via vertebral transposition and ligation of the subclavian artery was performed to prevent eventual thrombosis, emboli, and stroke.

Analysis of Later Stage Morbidity and Mortality after Pancreatic Surgery Because of Abdominal Trauma.

Background: Pancreatic trauma surgery is a complicated surgical procedure for severe pancreatic injuries, accompanied by a high incidence of complications and mortality. This study was designed to explore the long-term prognosis of pancreatic surgery because of abdominal trauma. Patients and Methods: The clinical data of 103 patients who were admitted to Jinling Hospital between August 2012 and August 2019 who had pancreatic trauma surgery were analyzed retrospectively. Results: All admissions involved pancreatic trauma surgery performed at an outside hospital network, which later transferred patients to our institution because of post-operative later-stage complications. Eight patients received American Association for the Surgery of Trauma (AAST) grade 1 or 2 pancreatic injuries and 95 received AAST grade 3, 4, or 5 pancreatic injuries. The primary surgical management of pancreatic injuries included drainage of the pancreatic injury (n = 28), repair of the pancreas (n = 35), partial pancreatectomy (n = 15), pancreaticojejunostomy (n = 6), and pancreaticoduodenectomy (n = 19). The most common mechanism of trauma was motor vehicle collision (n = 72), crush injury (n = 26), and stab wound (n = 5). Of 103 patients suffered varying degrees of gastrointestinal fistulae and intra-abdominal infections, there were 66 cases of pancreatic fistulae (64.1%), 49 cases of enteric fistulae (47.6%), 26 cases of colonic fistulae (25.2%), 14 cases of gastric or gastrointestinal anastomotic fistulae (13.6%), and 13 cases of biliary fistulae (12.6%). Ninety-five patients survived and eight patients died after therapy; the mean length of intensive care unit stay was 33 days. The number of patients who underwent emergency pancreaticoduodenectomy (EPD), the incidence of blood transfusion, the number of fistulae per patient, and the duration of mechanical ventilation and bacteremia in the mortality group were substantially higher than in the survival group (p < 0.05 each). The patients who underwent EPD had more grade 5 pancreatic injuries, more blood transfusions, higher peak total bilirubin, greater numbers of fistulae and open abdomen, and longer duration of mechanical ventilation and mortality than other patients (p < 0.05 each). Conclusions: The grade of pancreatic injury was associated with mortality and post-operative complications. The post-operative mortality and occurrence of complications of EPD because of abdominal trauma were significant; use of damage control surgery could potentially reduce the morbidity and mortality related to this procedure.

Safety and efficacy of transcarotid artery revascularization in a community hospital.

OBJECTIVE: We evaluated the outcomes and complications of transcarotid artery revascularization (TCAR) outside of academic vascular surgery programs. METHODS: An institutional review board-approved retrospective study was performed. Data from all cases of TCAR performed at a community hospital from May 2017 to February 2020 were collected and analyzed. Seven vascular surgeons performed the procedures after receiving appropriate training. The primary outcomes included technical success, the need for further revascularization, and major adverse events (death, cerebrovascular accident [CVA], myocardial infarction). The secondary outcomes included other adverse events and complications. The outcomes were assessed in the perioperative and 30-day follow-up periods. RESULTS: During a 33-month period, TCAR was completed in 147 of 149 attempted cases (98.7%). No patients required further revascularization. The perioperative and 30-day major adverse event rates were 0.7% (n = 1) and 3.4% (n = 5), respectively. One case of a minor perioperative CVA occurred. At 30 days, one patient had died. The 30-day complications included CVA (n = 1) and myocardial infarction (n = 3). The combined perioperative and 30-day minor complication rates were 2.7% and 1.4%, respectively. CONCLUSIONS: TCAR is a safe and effective method of carotid artery revascularization in a community hospital setting. This technology might help improve revascularization in patients without access to larger academic centers.

The Role of Manual Dexterity and Cognitive Functioning in Enhancing Resident Operative Autonomy.

INTRODUCTION: Autonomy, both operative and nonoperative, is one of the most critical aspects of successful surgical training. Both surgeon and resident share the responsibility of achieving this goal. We hypothesize that operative autonomy is distinct and depends, for the most part, on the resident's manual dexterity, knowledge of, and preparation for the procedure. METHODS: Over a period of 4 academic years, between July 2014 and June 2018, a total of 958 Global Rating Scale of Operative Performance evaluations were completed by 32 general and subspecialty faculty surgeons for 35 residents. Elective procedures were evaluated, including 165 (17.2%) by postgraduate year (PGY)1 residents, 253 (26.4%) by PGY2, 199 (20.8%) by PGY3, 147 (15.3%) by PGY4, and 194 (20.3%) by PGY5. The procedures evaluated were: 261 (27.2%) hernia repairs; 178 (18.6%) cholecystectomies; 102 (10.6%) colorectal and anal procedures; 73 (7.6%) vascular procedures; 56 (5.8%) thyroid and parathyroidectomies; 39 (4.1%) foregut (esophagus and stomach) procedures; 38 (4%) skin, soft tissue, and breast; 92 (10%) hepatopancreatic; 20 (2.1%) pediatric procedures; and 99 (10.3%) other procedures including amputations, cardiothoracic, and solid organs procedures. Each resident was scored from 1 to 5 (1 lowest, 5 highest) in each of the following categories of Global Rating Scale of Operative Performance: respect for tissue (RT), time and motion (T&M), instrument handling (IH), knowledge of the instrument (KI), flow of operation (FO) and resident's preparation for the procedure (RP). Resident operative autonomy (ROA) was assessed using the Zwisch scale, a 4-point scale describing faculty supervision behaviors associated with different degrees of resident autonomy (1: Show and Tell, 2: Active Help, 3: Passive Help, and 4: Supervision Only). RESULTS: Correlation and ordinal regression analyses were conducted to examine the relationship between ROA and manual dexterity (RT, T&M, IH, and FO), and cognitive functioning (knowledge of instruments and resident preparation). Results indicated a positive correlation between ROA and RT (r = 0.528, p < 0.001), T&M (r = 0.630, p < 0.001), IH (r = 0.597, p < 0.001), KI (r = 0.490, p < 0.001), FO (r = 0.637, p < 0.001), and RP (r = 0.525, p < 0.001). Additionally, there was a weak inverse correlation between ROA and the number of years the surgeon had been in practice (r = -0.127, p = 0.001). The significant predictors of resident autonomy found by the ordinal logistic regression include time and motion (p < 0.001), flow of operation (p < 0.001), and resident's preparation for the procedure (p < 0.001). CONCLUSIONS: Resident operative autonomy is a product of shared responsibility between the faculty and resident. However, residents' inherent and/or acquired skills and preparation for the operative procedures play a critical role. Residents should be advised to use available resources such as simulation to augment their skills preoperatively and to enhance their autonomy in the operating room.

Glomus faciale tumors: A report of 3 cases and literature review.

Our objectives in reporting this case series are to familiarize readers with the rare occurrence of paragangliomas originating along the facial nerve and to provide a literature review. We describe 3 such cases that occurred at our tertiary care academic medical center. Two women and 1 man presented with a tumor adjacent to the vertical segment of the facial nerve. The first patient, a 48-year-old woman, presented with what appeared to be a parotid tumor at the stylomastoid foramen; she underwent a parotidectomy, transmastoid facial nerve decompression, and a shave biopsy of the tumor. The second patient, a 66-year-old man, underwent surgery via a postauricular infratemporal fossa approach, and a complete tumor resection was achieved. The third patient, a 56-year-old woman, presented with a middle ear mass; she underwent complete tumor removal through a transmastoid transcanal approach. All 3 patients exhibited normal facial nerve function both before and after surgery. Paragangliomas of the facial nerve are extremely rare, and their signs and symptoms are unlike those of any other temporal bone glomus tumors. Management options include surgical resection, radiologic surveillance, and radiotherapy. The facial nerve can be spared in selected cases.
