Cardiac Tamponade due to Left Ventricular Pseudoaneurysm After Aortic Valve Replacement
The Heart Surgery Forum, 2013
Left ventricular outflow tract pseudoaneurysm is a rare but a potentially lethal complication, mainly after aortic root endocarditis or surgery. Usually, it originates from a dehiscence in the mitral-aortic intervalvular fibrosa and arises posteriorly to the aortic root. We report a rare case of a patient with cardiac tamponade due to left ventricular pseudoaneurysm after aortic valve replacement. The subsequent surgical resection was performed successfully.
Acute type A aortic dissection: the prognostic impact of preoperative cardiac tamponade
European Journal of Cardio-Thoracic Surgery, 2001
Objective: Acute type A aortic dissection requires emergency surgery and is associated with considerable mortality. The aim of the study was to evaluate whether occurrence of preoperative cardiac tamponade with or without palpable pulses in these patients is associated with higher incidence of multiple organ failure (MOF) and in-hospital mortality. Methods: A retrospective cohort study included 87 patients with acute type A aortic dissection, who were admitted via an emergency department between December 1991 and December 1999 for emergency surgery. Impending cardiac tamponade (with palpable pulses) and severe cardiac tamponade (without palpable pulses) were recorded and patients were followed for occurrence of MOF and/or in-hospital mortality. Results: Impending cardiac tamponade with palpable pulses was diagnosed in 33 patients (38%), signs of severe cardiac tamponade without palpable pulses were found in seven patients (8%). MOF occurred in 41 patients (47%); 32 patients (37%) died during the present stay, all of them had MOF. Preoperative severe cardiac tamponade without palpable pulses was associated with a significantly increased risk for poor outcome (odds ratio (ORÞ ¼ 16:1, 70% confidence interval (CI) 4.8-71.7, P ¼ 0:04), particularly preoperative death (n ¼ 6 of 7). Impending cardiac tamponade with palpable pulses (OR ¼ 1:6, 70% CI 0.8-3.3, P ¼ 0:2) was not associated with the occurrence of MOF/death. Hemodynamic shock (OR ¼ 6:5, 70% CI 3.0-13.9, P ¼ 0:01) was also associated with poor outcome. Conclusion: Patients with acute type A aortic dissection and signs of preoperative cardiac tamponade without palpable pulses had a 16-fold increased risk for poor outcome, particularly preoperative death. In contrast, cardiac tamponade with palpable pulses was not associated with increased frequency of MOF/in-hospital mortality. q
A standard experiment with emergency endovascular interventions on the descending thoracic aorta
World Journal Of Advanced Research and Reviews, 2023
Background: Using emergency endovascular aortic repair to treat severe acute aortic disorders affecting the descending aorta is an appealing prospect. Aim: This study's objective was to evaluate the efficacy of thoracic endovascular aortic repair (TEVAR) in the management of acute surgical emergencies involving the descending thoracic aorta. Methods: The medical records of every patient who underwent TEVAR in a single centre since 2007 were retrospectively evaluated. Emergency criteria for inclusion were used to treat patients with aortic disease who had complicated spontaneous acute aortic syndrome (csAAS), traumatic aortic acute injuries (TAIs), and other symptoms calling for urgent treatment. The Society for Vascular Surgery reporting guidelines for thoracic endovascular aortic repair were used to evaluate the technical and clinical success with regard to patient mortality, survival, and reoperation rate (TEVAR). Results: In 74 cases (51.0%), emergency procedures were required, including those involving patients with traumatic aortic acute injuries (TAIs) (31.1%) and complicated spontaneous acute aortic syndrome (csAAS) (64.8%; n = 48). Aortic iatrogenic dissection (AID) in one case and two other fistulas following the prior stent graft were also identified as implantation's. While 2 hybrid operations required extra approaches, all procedures were performed through surgically exposed femoral arteries. The main technical success rate was 95.9%; endoleak was recorded in 3 instances. In 94.5% of cases, the main clinical success was achieved. All of the patients made it through the endovascular procedures, however one of them passed away in the hospital as a result of multi-organ failure (early mortality: 1.3%). 11 patients passed away throughout the follow-up period, which lasted 6 to 164 months (median 67). The probability of survival over one year, five years, and 10 years was 86.4 ± 0.04%, 80.0 ± 0.05%, and 76.6 ± 0.06%, respectively. However, following TAI (95.2%) compared to scAAS (63.4%), the rate of 5-year survival was significantly greater (p=0.008). One person experienced temporary para-paresis right after the operation (1.3%). Throughout the postdischarge follow-up period, no more severe stent-graft-related adverse events were reported. Conclusion: The probability of survival over one year, five years, and 10 years was 86.4 ± 0.04%, 80.0 ± 0.05%, and 76.6 ± 0.06%, respectively. However, following TAI (95.2%) compared to scAAS (63.4%), the rate of 5-year survival was significantly greater (p=0.008).

Emergency Procedures on the Descending Thoracic Aorta in the Endovascular Era
Journal of Vascular Surgery, 2010
Background: Thoracic endovascular aortic repair (TEVAR), initially developed for the treatment of degenerative aneurysms of the descending thoracic aorta, has been applied to the entire spectrum of descending thoracic aortic pathology in both the elective and emergent settings. This single center study evaluates the effectiveness of TEVAR for the treatment of acute surgical emergencies involving the descending thoracic aorta, including traumatic aortic disruption (TAD), ruptured descending thoracic aneurysm (RDTA), and acute complicated Type B dissection (cTBD). Methods: A retrospective review of the medical records of all patients undergoing emergent TEVAR at the University of Mississippi Medical Center between August 2007 and November 2010 was undertaken. Patients were studied for 30-day survival, complications, type of device used for the repair, and technical aspects of the procedure. Results: A total of 44 patients (59% male) with an average age of 49 years (range, 16-87 years) underwent emergent TEVAR during the study period. The technical success rate was 100%, with no patient requiring emergent open surgery for conditions involving the descending thoracic aorta at our institution during the study period. The majority (73%) of the repairs were accomplished using commercially available thoracic stent grafts. Abdominal endograft proximal extension cuffs were used in 12 (38%) of the 32 patients undergoing repair of TAD. Twenty-one patients (48%) required coverage of the left subclavian artery, two (10%) of whom subsequently required subclavian artery revascularization. Procedure-related complications included two strokes, one spinal cord ischemia, one unintentional coverage of the left carotid artery, one episode of acute renal failure, and three access site injuries. One patient undergoing repair of TAD had collapse of the stent graft in the early postoperative period. He was successfully treated by placement of an additional stent graft. Seven patients (16%) died within 30 days of surgery. Three of the deaths occurred in patients who had successfully undergone repair of a TAD and died of associated injuries. Conclusions: Emergent TEVAR has become the treatment of choice for acute surgical emergencies involving the descending thoracic aorta. Short-term morbidity and mortality compare favorably with historic results for emergent open surgical procedures on the descending thoracic aorta. Survival is highest in patients undergoing repair of TAD. Using current endograft technology, nearly all emergent conditions of the descending thoracic aorta can be successfully treated with TEVAR.
Cardiac Tamponade Complicating Aortic Dissection
Aortic dissection is a relatively rare but dreadful illness, often presenting with tearing chest pain and acute hemodynamic compromise. We report a case of a patient with suspected food poisoning that turned out to be aortic dissection. With high level of suspicion, the patient was diagnosed at the earliest but soon developed cardiac tamponade for which pericardiocentesis was done, but the patient developed cardiac arrest and died within few hours of presentation to the hospital. We discuss the controversial role of pericadiocentesis in cardiac tamponade complicating aortic dissection.

Background: Elective thoracic endovascular aortic repair in selected patients with suitable aortic anatomy is associated with low morbidity and mortality, and is gaining widespread acceptance. Its benefit in acute thoracic aorta diseases, however, has not yet been demonstrated in highnumbered studies. This report presents data of the Talent Thoracic Retrospective Registry (TTR) of all patients who underwent endovascular stent grafting for acute thoracic aorta pathology. Methods: Between December 1996 and July 2004 data were collected regarding 113 consecutive patients who underwent emergent endovascular stent grafting of the thoracic aorta using the Talent thoracic stent graft (Medtronic, Inc., Santa Rosa, California) in 7 European referral centers. Acute thoracic aorta pathology consisted of 41 (36.3 %) traumatic aortic injuries, 37 (32.7 %) Stanford type B dissections, 5 (4.4 %) intramural hematomas, 18 (15.9 %) thoracic aorta aneurysms, 4 (3.5 %) pseudoaneurysms and 8 (7.1 %) penetrating ulcers. Results: In all patients the stent graft system could be introduced via the common femoral artery. Conversion to open surgical repair was necessary in 2 patients, one in the early phase due to persistent bleeding via backflow in the false lumen from a distal entry tear, and another patient in a late phase due to retrograde dissection. Intraoperative mortality was 1.8%, one patient suffered a massive myocardial infarction, and another died of tamponade secondary to retrograde dissection. Overall hospital mortality was 8.0% (9 patients). In only 2 of them, it was considered a stent graft procedure related death. New neurological symptoms were seen in 6.2% (7 patients), with complete recovery in 5 patients. Mean follow-up was 15 months (range 1-69 months). Late mortality was 8.7% (9 patients). Only one late death was considered aorta related. Overall re-intervention rate was 8.9% (n = 10) and was mainly for type I endoleak or persistent false lumen perfusion. Conclusion: Subanalysis of the Talent Thoracic Retrospective Registry for endovascular stent grafting of acute thoracic aorta pathology in over 100 consecutive patients demonstrated its feasibility, with low morbidity and acceptable low mortality rates.
