The operative treatment of 26 aorto-caval fistulas during the last 18 years is reviewed (24 male and two female patients; average of 65.3 year). Out of 1698 cases presenting an abdominal aortic aneurysm, 406 presented with rupture, and 26 had aorto caval fistula. In 24 cases (92.3%) it concerned an atherosclerotic aneurysm. One aneurysm with aorto-caval fistula was secondary to abdominal blunt trauma (3.8%), and one due to iatrogenic injury (3.8%). The time interval between first clinical signs of aorto-caval fistula and diagnosis, ranged from 6 hours to 2 years (average 57,3 days). Clinical presentation included congestive heart failure infive patients (11.5%), extreme leg edema in 13 (50.0%), hematuria in 2 (7.0%), renal insufficiency 2 (7.0%), and scrotal edema in six patients. Diagnosis was made by means of color duplex scan in eight patients (30.7%), CT in seven patients (27%), NMR in three patients (11.5%), and angiography in seven patients (27%). Most reliable physical sign was an abdominal bruit,present in 20 patients (77%). In ten patients (38.4%) correct diagnosis was not made prior to surgery. The operative treatment consisted of transaortic suture of the vena cava (25 pts-96.0%), and aneurysm repair. Five operative deaths occurred (19,2%), and for all of them it concerned a misdiagnosis. Cause of death was myocardial infarction (one patient-3.8%), massive bleeding (one patient-3.8%), MOF (two patients-7, 0%), and colon gangrene (one patient-3.8%). Follow-up period varied from six months to 18 years (mean 4 years and two months). Long term results showed a 96% patency rate. No postoperative lower extremity venous insufficiency nor pelvic venous hypertension was observed post-operatively.

The abdominal compartment syndrome (ACS) is defined a situation of high degrade abdominal hypertension (IAH) with clinicals signs of multiorganic dysfunction. It's observed like in the intensive care, in particular surgycals and postraumatics, there is ever a bigger frequence of complications presented by criticals patients. The various trials remark a changeable incidence, but the common factor is characterized by a particular severity of scores. All the possibles mechanicals, haemorragicals, infiammatories, and postraumatics causes act, but don't enable the stability among abdominal content, abdominal compliance and parietal tension. The initial triad of effects is constitued by the elevation of diaphragm and the visceral and vascular compression; after this triad provoke a pathophysiologic system that, through various levels, bring to a respiratory, renal and cardiocirculatory dysfunction and to a parietal, hepatic and intestinal ischemia with consequent bacterical translation: sepsis and MOF. The Burch's classification (1996) report four levels of gravity by the slight (< 15 mmHg) to the heavyest (> 35 mmHg): the firsts two levels are of intensivistic competence and for the detention are used conservatives metodics and pharmacological approach; instead in the lasts two levels it's necessary to foresee a surgycal treatment of laparotomy, washing and drainage with following temporary paret's closure. The mortality is now very elevated (29-62%) especially when it's already established a multiorganical dysfunction; therefore it's necessary forward its appearance through the monitorization of abdominal pression (IAP) with the measurement of vescical pression in alls criticals patients at the aim to treat immediately the firsts signs of IAH.

A recently developed pneumonia caused by SARS-CoV-2 bursting in Wuhan, China, has quickly spread across the world. We report the clinical characteristics of 82 cases of death from COVID-19 in a single center. Clinical data on 82 death cases laboratory-confirmed as SARS-CoV-2 infection were obtained from a Wuhan local hospital's electronic medical records according to previously designed standardized data collection forms. All patients were local residents of Wuhan, and a large proportion of them were diagnosed with severe illness when admitted. Due to the overwhelming of our system, a total of 14 patients (17.1%) were treated in the ICU, 83% of deaths never received Critical Care Support, only 40% had mechanical ventilation support despite 100% needing oxygen and the leading cause of death being pulmonary. Most of the patients who died were male (65.9%). More than half of the patients who died were older than 60 years (80.5%), and the median age was 72.5 years. The bulk of the patients who died had comorbidities (76.8%), including hypertension (56.1%), heart disease (20.7%), diabetes (18.3%), cerebrovascular disease (12.2%), and cancer (7.3%). Respiratory failure remained the leading cause of death (69.5%), followed by sepsis/MOF (28.0%), cardiac failure (14.6%), hemorrhage (6.1%), and renal failure (3.7%). Furthermore, respiratory, cardiac, hemorrhagic, hepatic, and renal damage were found in 100%, 89%, 80.5%, 78.0%, and 31.7% of patients, respectively. On admission, lymphopenia (89.2%), neutrophilia (74.3%), and thrombocytopenia (24.3%) were usually observed. Most patients had a high neutrophil-to-lymphocyte ratio of >5 (94.5%), high systemic immune-inflammation index of >500 (89.2%), and increased C-reactive protein (100%), lactate dehydrogenase (93.2%), and D-dimer (97.1%) levels. A high level of IL-6 (>10 pg/ml) was observed in all detected patients. The median time from initial symptoms to death was 15 days (IQR 11-20), and a significant association between aspartate aminotransferase (p = 0.002), alanine aminotransferase (p = 0.037) and time from initial symptoms to death was remarkably observed. Older males with comorbidities are more likely to develop severe disease and even die from SARS-CoV-2 infection. Respiratory failure is the main cause of COVID-19, but the virus itself and cytokine release syndrome-mediated damage to other organs, including cardiac, renal, hepatic, and hemorrhagic damage, should be taken seriously as well.
