[Long-term results of carotid endarterectomy and carotid artery stenting in patients with high bifurcation of common carotid artery: a multiple-center study]. / Otdalennye rezul'taty karotidnoi endarterektomii i karotidnoi angioplastiki so stentirovaniem u patsientov s vysokim raspolozheniem bifurkatsii obshchei sonnoi arterii. Rezul'taty mnogotsentrovogo issledovaniya.

OBJECTIVE: To analyze in-hospital and long-term results of eversion carotid endarterectomy (CEE), carotid endarterectomy with patch repair and carotid artery stenting (CAS) in patients with high bifurcation of common carotid artery. MATERIAL AND METHODS: A retrospective multiple-center open study included 1983 patients who underwent internal carotid artery (ICA) repair for severe stenosis between 2010 and 2021. Three groups of patients were distinguished depending on revascularization option: group 1 (n=638) - eversion CEE; group 2 (n=351) - CEE with patch repair; group 3 (n=994) - CAS. RESULTS: In-hospital postoperative mortality and incidence of stroke and myocardial infarction were similar. All bleedings (n=39) occurred after CEE. ICA thrombosis was diagnosed in groups 1 and 2 due to intimal detachment after insertion of temporary bypass tube. Incidence of laryngeal paresis, neuropathy of hypoglossal and glossopharyngeal nerves, Horner syndrome, damage to salivary glands was comparable in groups 1 and 2. Long-term mortality was the highest (n=10; 2.8%) after CEE with patch repair due to fatal stroke. In turn, the highest incidence of ICA restenosis and restenosis-induced ischemic stroke was observed after CEE with patch repair and CAS. CONCLUSION: 1. Classical and eversion CEE in patients with high CCA bifurcation is followed by high in-hospital incidence of damage to cranial nerves and salivary glands, laryngeal paresis, Horner syndrome, bleeding and risk of ICA thrombosis. 2. In patients with high CCA bifurcation, CAS and CEE with patch repair are accompanied by high incidence of ICA restenosis, restenosis-induced stroke and mortality in long-term postoperative period. 3. Eversion CEE demonstrates the lowest rates of all adverse cardiovascular events in long-term follow-up period.

[Parkinson syndromes: aspects of social medical care]. / Parkinson-Syndrome: Aspekte der sozialmedizinischen Versorgung.

Parkinson syndromes (PS) represent frequent neurodegenerative disorders. The demographic change suggests an increasing prevalence of PS in the near future. Treatment expenses, early retirement and need of long-term care result in rising public health care expenditures. Standardised concepts of care do not only improve the quality of patient-centered care, but also help to minimize its consequential costs. Their implementation requires profound knowledge of therapeutic strategies and sociomedical regulations. Medical treatment and sociomedical care have to be regularly reevaluated and adapted to the patient's needs and disease severity. An optimal therapy concept guarantees the patient's long term social integration and improves the compliance.

Through the 10-mm Looking Glass: Advances in Minimally Invasive Surgery in Trauma.

BACKGROUND: Minimally invasive surgery is increasingly being used in trauma surgery as both a diagnostic and a therapeutic tool. However, significant debate regarding the accuracy, safety, and indications for minimally invasive surgery in trauma continues to impede widespread acceptance of these techniques among trauma surgeons. METHOD: Herein, we report a contemporary review of the current role of both laparoscopy and thoracoscopy in modern trauma surgery. Literature search was performed using PubMed database and the following keywords: "Trauma," "Minimally Invasive Surgery," "Laparoscopy," and "Thoracoscopy." RESULTS: Current recommendations advocate for the use of laparoscopy as a diagnostic tool in penetrating trauma for the diagnosis of diaphragm injuries and peritoneal violation. A significant body of research demonstrates that laparoscopy in select hemodynamically normal patients can significantly decrease nontherapeutic laparotomy rates and hospital costs and is highly sensitive and specific with very low missed injury rates, including small bowel injuries. Laparoscopic repairs to a wide breadth of abdominal and thoracic injuries have been reported with impressive results. Adherence to a standardized laparoscopic examination system and routine use of laparoscopy in elective or acute care practice strongly influence positive results with minimally invasive surgery in trauma. Video-assisted thoracoscopic surgery is most commonly used for evaluation of diaphragm, evacuation of retained hemothorax, and management of ongoing bleeding post-trauma. CONCLUSION: Minimally invasive surgery does offer several advantages compared to traditional open surgery and should be considered as an additional tool in the trauma surgeon's armamentarium in the care of select injured patients.

Post-Earthquake Injuries Treated at a Field Hospital ù Haiti, 2010

Afin de caractériser les blessures et les interventions chirurgicales effectuées par l'UMGI/PM et d'évaluer les besoins spéciaux médicaux, chirurgicaux et de réadaptation, l'UMGI/PM et le "Centers for Disease Control and Prevention" (CDC) mènent une analyse rétrospective de tous les dossiers médicaux de malades disponibles pour la période du 13 janvier au 28 mai 2010. Le premier article de cette revue décrit les résultats de cette analyse et présente les données quantitatives obtenues.

Randomized clinical trial of intermittent pneumatic compression and low molecular weight heparin in trauma.

BACKGROUND: After trauma, up to 60 per cent of immobilized patients have been reported to develop a silent deep vein thrombosis (DVT). No large, prospective randomized trials have tested the efficacy of intermittent pneumatic compression (IPC) devices in these patients. METHODS: A prospective randomized trial was performed of 442 patients who received thromboprophylaxis using either an IPC device or low molecular weight heparin (LMWH). Duplex imaging was performed on both legs on admission, and was repeated weekly thereafter until discharge, at 30 days or when there was a thrombotic event, whichever occurred first. RESULTS: There were no significant differences in time spent in intensive care, or the proportion of patients with pelvic fractures, spinal cord or head injuries between the two groups. Six patients (2.7 per cent) developed a DVT in the IPC group and one (0.5 per cent) in the LMWH group (P = 0.122). Pulmonary embolism occurred in one patient in each group. There were 13 minor bleeding episodes (four in the IPC group and nine in the LMWH group) and eight major bleeding episodes (four in each group), none of which required operative intervention. CONCLUSION: The low rate of thromboembolic complications and the cost savings suggest that IPC might be used safely and effectively for thromboprophylaxis in trauma patients.

Evaluating blunt abdominal trauma with sonography: a cost analysis.

Ultrasonography (US) is becoming increasingly utilized in the United States for the evaluation of blunt abdominal trauma (BAT). The objective of this study was to assess the cost impact of utilizing US in the evaluation of patients with BAT in a major trauma center. All patients sustaining BAT during a 6-month period before US was used at our institution (Jan-Jun 1993) were compared to BAT patients from a recent period in which US has been utilized (Jan-Jun 1995). The numbers of US, computed tomography (CT), and diagnostic peritoneal lavage (DPL) were tabulated for each group. Financial cost for each of these procedures as determined by our finance department were as follows: US $96, CT $494, DPL $137. These numbers are representative of actual hospital expenditures exclusive of physician fees as calculated in 1994 U.S. dollars. Cost analysis was performed with t test and chi squared test, and significance was defined as P < 0.05. There were 890 BAT admissions in the 1993 study period and 1033 admissions in the 1995 study period. During the 1993 period, 642 procedures were performed on the 890 patients to evaluate the abdomen: 0 US, 466 CT, and 176 DPL (see table) [table: see text]. This compares to 801 procedures on the 1,033 patients in 1995: 552 US, 228 CT, and 21 DPL. Total cost was $254,316 for the 1993 group and $168,501 for the 1995 group. Extrapolated to a 1-year period, a significant (P < 0.05) cost savings of $171,630 would be realized. Cost per patient evaluated was significantly reduced from $285.75 in 1993 to $163.12 in 1995 (P < 0.05). This represents a 43 per cent reduction in per patient expenditure for evaluating the abdomen. By effectively utilizing ultrasonography in the evaluation of patients with blunt abdominal trauma, a significant cost savings can be realized. This effect results chiefly from an eight-fold reduction in the use of DPL, and a two-fold reduction in the use of CT.

Prospective randomized trial of two wound management strategies for dirty abdominal wounds.

OBJECTIVE: To determine the optimal method of wound closure for dirty abdominal wounds. SUMMARY BACKGROUND DATA: The rate of wound infection for dirty abdominal wounds is approximately 40%, but the optimal method of wound closure remains controversial. Three randomized studies comparing delayed primary closure (DPC) with primary closure (PC) have not conclusively shown any advantage of one method over the other in terms of wound infection. METHODS: Fifty-one patients with dirty abdominal wounds related to perforated appendicitis, other perforated viscus, traumatic injuries more than 4 hours old, or intraabdominal abscesses were enrolled. Patients were stratified by cause (appendicitis vs. all other causes) and prospectively randomized to one of two wound management strategies: E/DPC (wound packed with saline-soaked gauze, evaluated 3 days after surgery for closure the next day if appropriate) or PC. In the E/DPC group, wounds that were not pristine when examined on postoperative day 3 were not closed and daily dressing changes were instituted. Wounds were considered infected if purulence discharged from the wound, or possibly infected if signs of inflammation or a serous discharge developed. RESULTS: Two patients were withdrawn because they died less than 72 hours after surgery. The wound infection rate was greater in the PC group than in the E/DPC group. Lengths of hospital stay and hospital charges were similar between the two groups. CONCLUSION: A strategy of DPC for appropriate dirty abdominal wounds 4 days after surgery produced a decreased wound infection rate compared with PC without increasing the length of stay or cost.

Incidence and susceptibility of pathogenic bacteria vary between intensive care units within a single hospital: implications for empiric antibiotic strategies.

BACKGROUND: The purpose of this study was to determine whether the incidence of recovery and patterns of antibiotic susceptibility of pathogenic bacteria vary between intensive care units (ICUs) in a single teaching hospital. METHODS: Culture and susceptibility results were collected prospectively for a 3-month period (April through June 1999) in each of the surgical, trauma, and medical ICUs. The number of unique isolates and susceptibility patterns were determined. Susceptibility of isolates among ICUs was compared with chi2. RESULTS: Statistically significant differences between ICUs in susceptibility to various antibiotics were found for Staphylococcus aureus, Enterococcus sp, Acinetobacter sp, Enterobacter sp, Klebsiella sp, and Pseudomonas sp. Notably, vancomycin-resistant Enterococcus was not seen in the medical ICU, whereas it was seen in both the surgical and trauma ICUs. Klebsiella spp resistant to ceftazidime were seen only in the trauma ICU. The aminoglycosides and quinolones had attenuated activity against Pseudomonas sp in the surgical ICU, whereas they remained highly effective in the trauma ICU. Cefazolin had no activity against the Enterobacter sp in either of the surgical ICUs, but was highly effective in the medical ICU. CONCLUSION: Although the microbiologic results of this study should not be extrapolated to other institutions, the principle is of value. There is variability between ICUs in a single large teaching hospital in susceptibility of bacterial pathogens to various antibiotics. This may have implications in the design of empiric antibiotic strategies and the planning of the hospital formulary. Hospital wide or composite ICU antibiograms are inadequate for planning empiric therapy in the ICU.

Gram positive infection in trauma patients: new strategies to decrease emerging Gram-positive resistance and vancomycin toxicity.

Bacterial resistance to antibiotics has become a serious problem in medicine. Particularly worrisome is the increasing incidence of multi-resistant organisms such as methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE). Not surprisingly, in view of the high incidence of life-threatening infections and heavy antibiotic use, resistance has become very frequent and problematic in intensive care units. The standard approach for the treatment of MRSA is vancomycin or teicoplanin. Long-term therapeutic and unrestricted prophylactic use of vancomycin has given rise to VRE which in turn may lead to the emergence of vancomycin-resistant S. aureus (VRSA) through plasmid mediated transmission. In order to reduce the incidence of VRE and to avoid the emergence of VRSA, vancomycin use should be restricted and alternative antibiotic strategies should be developed. Using those antibiotics to which MRSA are still generally sensitive, perhaps in combination with new ones, such as, quinupristin/dalfopristin, should be entertained. We performed a retrospective review of the Gram-positive infections in our Level 1 Trauma Center Intensive Care Unit, and an analysis of the resistance patterns of the NMSA infections showed that additional resistance rarely develops within less than 5 days. We then designed a new strategy for the treatment of MRSA infections. This strategy consists of the sequential use of a range of antibiotics with activity against MRSA in short 5-7 day pulses until the full clinical course is completed. Studies validating the benefit of this approach are currently in preparation.

The role of computed tomography in selective management of gunshot wounds to the abdomen and flank.

OBJECTIVE: To determine whether computed tomography (CT) is an accurate diagnostic modality for the triage of hemodynamically stable patients with gunshot wounds of the abdomen and flank. METHODS: A chart review of 83 trauma patients for whom abdominal CT was used as initial screening. RESULTS: In 53 patients, CT revealed no evidence of peritoneal penetration, and in 15 patients, there was evidence of either peritoneal penetration or liver injury. There were no false results in these patients. Among 15 patients with questionable peritoneal penetration, cavitary endoscopy was performed in 11 and exploratory laparotomy was performed in 3, and 1 patient was initially observed and subsequently underwent exploratory surgery for a missed colonic injury. CONCLUSION: In selected centers and in hemodynamically stable patients with abdominal and flank gunshot wounds, abdominal CT can be an effective and safe initial screening modality to document the presence or absence of peritoneal penetration and to manage nonoperatively stable patients with liver injuries. If there is any question of peritoneal penetration, cavitary endoscopy should be part of the protocol of nonoperative management.

Thoracoscopy in the evaluation and management of thoracic trauma.

Video-thoracoscopy was used to evaluate and manage patients after thoracic trauma. It was used in 29 patients. Indications included retained hemothorax in 16 patients, empyema in 11, evaluation for the source of thoracic bleeding in 1, and an airleak in 1. The mechanism of injury was blunt trauma in 8 cases, 10 with stab wounds, and 11 with gunshot wounds. In blunt trauma, thoracoscopy was carried out an average of 11.7 days post injury, chest tubes were removed after an average of 7 days post thoracoscopy, and discharge averaged 10.7 days after thoracoscopy. The failure rate was 12.5% with no mortality. In stab wounds, it was carried out an average of 8.8 days post injury, chest tube removal occurred after 6.1 days, and discharge averaged 7.8 days after thoracoscopy. The failure rate was 20% with no mortality. In gunshot wounds, it was carried out an average of 7.5 days after injury, chest tubes were removed after 9.9 days, and discharge averaged 16 days post thoracoscopy. The failure rate was 9% with a mortality of 9%. Overall, the failure rate for thoracoscopy was 13.8% (4/29). The mortality rate was 3.5% (1/29). It was successfully performed up to 30 days post injury. It proved to be effective in the management of empyema, evacuation of clotted hemothorax, and diagnosis of ongoing thoracic bleeding.

Laparoscopic cholecystectomy in cirrhotic patients.

BACKGROUND: Reported mortality for open cholecystectomy in patients with cirrhosis ranges from 10% to 80%. Laparoscopic cholecystectomy has gained acceptance in the general population and has become the procedure of choice for symptomatic cholelithiasis. We reviewed our experience with the use of laparoscopic cholecystectomy in this group. STUDY DESIGN: We did a retrospective review of the records of 25 consecutive laparoscopic choleoystectomy procedures performed on cirrhotic patients from May 1992 to July 1996. RESULTS: There were no mortalities in our group. All procedures were completed laparoscopically. Mean length of stay was 1.7 days (range, 1 to 8 days). Morbidity consisted of wound hematomas, pneumonia, and ascites for a rate of 32%. Only patients with Child's Class A and Class B cirrhosis were operated on. CONCLUSIONS: Laparoscopic cholecystectomy can be performed safely in cirrhotic patients with well compensated liver function.

The role of liver transplantation in the subacute trauma patients.

Two case reports are presented involving complex liver traumas requiring the need for liver transplantation. Both of these patients were designated unsalvageable until the transplant team was consulted. It is imperative that surgeons involved with complex hepatic trauma not give up hope and include these patients as potential liver recipients when irreversible liver failure occurs.

Personal watercraft crash injuries: an emerging problem.

BACKGROUND: The increased popularity of personal watercraft (PWC) has resulted in an increase in PWC-related injuries. In an effort to better understand the problem, a retrospective review of 37 victims of such injuries seen at a Level I trauma center and fatalities examined by the medical examiner were analyzed. RESULTS: Fourteen percent of the victims were passengers, two of whom were struck from behind, resulting in severe injuries. Twelve patients died of their injuries. For six victims, the cause of death was drowning; only one of these victims was wearing a personal flotation device. Two patients sustained transected aortas, 20% had brain injuries, 20% had spinal fractures, and 48% had skeletal and skull fractures. Abdominal organ injuries were present in only 13.5% of the victims, but they were significant, with liver, spleen, and kidney lacerations and aortic and renal artery injuries. CONCLUSION: In this population of victims of PWC crashes meeting preestablished trauma criteria or on-scene deaths, injuries were significant. Many of the drowning deaths may have been prevented with the use of personal flotation devices. The potential for serious intra-abdominal injury must be recognized and dealt with appropriately.

Pyloric exclusion in the management of duodenal trauma: is concomitant gastrojejunostomy necessary?

Pyloric exclusion with gastrojejunostomy (PE-GJ) has been recommended in patients with severe injuries to the pancreatoduodenal complex. Recently, the management philosophy for pancreatoduodenal injuries has been that less treatment is probably the best treatment. But whether gastrojejunostomy (GJ) should be used routinely with pyloric exclusion (PE) remains controversial. A retrospective review was conducted of patients who underwent PE at a Level I trauma center during a 36-month period. Forty-five patients had duodenal injuries and 12 of these (27%) underwent PE for management of complex duodenal injuries. Gunshot wounds were the cause of the injuries in 10 of the 12 patients (83%). Eight patients (67%) underwent PE-GJ and had a mean hospital stay of 25 days. Four patients (33%) underwent PE alone and had a mean hospital stay of 29 days. All 12 patients had spontaneous opening of the PE, regardless of the technique used. One patient (12.5%) in the PE-GJ group developed marginal ulceration and significant hemorrhage, and one patient died in the PE-GJ group. The reported incidence of marginal ulceration in the PE-GJ group, the spontaneous opening of the pylorus, and the need to limit the extent of surgical repair to focus on all other associated lesions present in these patients, suggest that GJ should not be used routinely in patients undergoing PE for the management of severe pancreatoduodenal injuries.

A technique for prolonged arterial infusions of fibrinolytic agents in the immediate postoperative period through a cutaneous venostomy.

Prolonged use of fibrinolytic agents post thrombectomy is limited by present techniques that require arterial puncture and indwelling arterial catheters. This limitation can be avoided by attaching a short segment of saphenous vein to the arteriotomy used for the thrombectomy and bringing this out to the skin as a "venostomy"; thus providing ready access to the vascular tree for arteriography, prolonged infusion of thrombolytic agents, or selective catheter placement. In delayed thrombectomies (Categories 2 & 3 as described by the Ad Hoc Committee on Reporting Standards, J Vasc Surg 1986;4:80-94), extending the use of these agents may represent the only hope for limb salvage.
