Rupture of the right ventricular free wall after myocardial infarction

Patient, 75 years-old, with free wall rupture of the right ventricle, corrected with prolene 3.0 points anchored in bovine pericardium patch, promoting the closure of the rupture. The patient was discharged on the 59th day after surgery in good clinical ans laboratorial conditions.

Angiographic Results in Intracranial Aneurysms Treated with Inert Platinum Coils

This study was designed in an attempt to identify the risk factors that could be significantly associated with angio graphic recurrences after selective endovascular treatment of aneurysms with inert platinum coils. A retrospective analysis of all patients with selective endovascular coil occlusion of intracranial aneurysms was prospectively collected from 1999 to 2003. There were 455 aneurysms treated with inert platinum coils and followed by digital subtraction angiography. Angio graphic results were classified according Roy and Raymond's classification. Recurrences were subjectively divided into minor and major. The most significant predictors for angio graphic recurrences were determined by ANOVAs logistic regression, Cochran-Mantel-Haenszel test, Fisher exact probability. Short-term (4.3 +/- 1.4 months) follow-up angiograms were available in 377 aneurysms, middle-term (14.1 +/- 4.0 months) in 327 and long-term (37.4 +/- 11.5 months) in 180. Recurrences were found in 26.8% of treated aneurysms with a mean of 21 +/- 15.7 months of follow-up. Major recurrences needing retreatment were present in 8.8% during a mean period follow-up of 17.9 +/- 12.29 months after the initial endovascular treatment. One patient (0.2%) experienced a bleed during the follow-up period. Recurrences after endovascular treatment of aneurysms with inert platinum coils are frequent, but hemorrhages are unusual. Single aneurysm, ruptured aneurysm, neck greater than 4 mm and time of follow-up were risk factors for recurrence after endovascular treatment. The retreatment of recurrent aneurysm decreases the risk of major recurrences 9.8 times. Long-term angiogram monitoring is necessary for the population with significant recurrence predictors.

Outcomes of ruptured abdominal aortic aneurysm

Ruptured abdominal aortic aneurysm (RAAA) is a life-threatening event, and without operative treatment the patient will die. The overall mortality can be as high as 80-90%; thus repair of RAAA should be attempted whenever feasible. The quality of life (QoL) has become an increasingly important outcome measure in vascular surgery. Aim of the study was to evaluate outcomes of RAAA and to find out predictors of mortality. In Helsinki and Uusimaa district 626 patients were identified to have RAAA in 1996-2004. Altogether 352 of them were admitted to Helsinki University Central Hospital (HUCH). Based on Finnvasc Registry, 836 RAAA patients underwent repair of RAAA in 1991-1999. The 30-day operative mortality, hospital and population-based mortality were assessed, and the effect of regional centralisation and improving in-hospital quality on the outcome of RAAA. QoL was evaluated by a RAND-36 questionnaire of survivors of RAAA. Quality-adjusted life years (QALYs), which measure length and QoL, were calculated using the EQ-5D index and estimation of life expectancy. The predictors of outcome after RAAA were assessed at admission and 48 hours after repair of RAAA. The 30-day operative mortality rate was 38% in HUCH and 44% nationwide, whereas the hospital mortality was 45% in HUCH. Population-based mortality was 69% in 1996-2004 and 56% in 2003-2004. After organisational changes were undertaken, the mortality decreased significantly at all levels. Among the survivors, the QoL was almost equal when compared with norms of age- and sex-matched controls; only physical functioning was slightly impaired. Successful repair of RAAA gave a mean of 4.1 (0-30.9) QALYs for all RAAA patients, although non-survivors were included. The preoperative Glasgow Aneurysm Score was an independent predictor of 30-day operative mortality after RAAA, and it also predicted the outcome at 48- hours for initial survivors of repair of RAAA. A high Glasgow Aneurysm Score and high age were associated with low numbers of QALYs to be achieved. Organ dysfunction measured by the Sequential Organ Failure Assessment (SOFA) score at 48 hours after repair of RAAA was the strongest predictor of death. In conclusion surgery of RAAA is a life-saving and cost-effective procedure. The centralisation of vascular emergencies improved the outcome of RAAA patients. The survivors had a good QoL after RAAA. Predictive models can be used on individual level only to provide supplementary information for clinical decision-making due to their moderate discriminatory value. These results support an active operation policy, as there is no reliable measure to predict the outcome after RAAA.

Acute subdural hematoma from ruptured cerebral aneurysm

The combination of ruptured aneurysms with acute subdural hematomas (aSDHs) is a rare presentation. Patients with aSDH associated with aneurysmal bleeding represent a subgroup within the spectrum of aneurysmatic hemorrhage. We summarize the clinical characteristics, diagnostic evaluation, and management of a series of cases presenting with aSDH associated with aneurysmal subarachnoid hemorrhage (SAH).

Repair of ruptured abdominal aortic aneurysm in octogenarians

To determine whether advanced age was independently associated with prohibitive surgical risks or impaired long-term prognosis after ruptured aortic aneurysm repair.

Endovascular suitability and outcome after open surgery for ruptured abdominal aortic aneurysm

Endovascular repair of ruptured abdominal aortic aneurysm (rAAA) has rapidly gained popularity, but superior results may be biased by patient selection. The aim was to investigate whether suitability for endovascular repair predicted survival, irrespective of technique of repair.

Delayed volume resuscitation during initial management of ruptured abdominal aortic aneurysm

In acute traumatic bleeding, permissive arterial hypotension with delayed volume resuscitation is an established lifesaving concept as abridge to surgical control. This study investigated whether preoperatively administered volume also correlated inversely with survival after ruptured abdominal aortic aneurysm (rAAA).

The management of ruptured abdominal aortic aneurysms: screening for abdominal aortic aneurysm and incidence of rupture

Twenty-five years have passed since the first randomised controlled trial began its recruitment for screening for abdominal aortic aneurysm (AAA) in men aged 65 and above. Since this and other randomised trials, all launched in the late 80s and 90s of the last century, the epidemiologic profile of abdominal aortic aneurysm may have changed. The trials reported an AAA prevalence in the range of 4-7% for men aged 65 years or more. AAA-related mortality was significantly improved by screening, and after 13 years, the largest trial showed a benefit for all-cause mortality. Screening also was shown to be cost-effective. Today, there are studies showing a substantial decrease of AAA prevalence to sometimes less than 2% in men aged ≥ 65 years and there is evidence that the incidence of ruptured aneurysm and mortality from AAA is also declining. This decline preceded the implementation of screening programmes but may be due to a change in risk factor management. The prevalence of smoking has decreased and there has been improvement in the control of hypertension and a rising use of statins for cardiovascular risk prevention. Additionally, there is a shift of the burden to the older age group of ≥ 75 years. Such radical changes may influence screening policy and it is worth reflecting on the optimum age of screening - it might be better to screen at ages >65 years - or rescreening 5 to 10 years after the first screen.

Management of Patients Presenting with Acute Subdural Hematoma due to Ruptured Intracranial Aneurysm

Acute subdural hematoma is a rare presentation of ruptured aneurysms. The rarity of the disease makes it difficult to establish reliable clinical guidelines. Many patients present comatose and differential diagnosis is complicated due to aneurysm rupture results in or mimics traumatic brain injury. Fast decision-making is required to treat this life-threatening condition. Determining initial diagnostic studies, as well as making treatment decisions, can be complicated by rapid deterioration of the patient, and the mixture of symptoms due to the subarachnoid hemorrhage or mass effect of the hematoma. This paper reviews initial clinical and radiological findings, diagnostic approaches, treatment modalities, and outcome of patients presenting with aneurysmal subarachnoid hemorrhage complicated by acute subdural hematoma. Clinical strategies used by several authors over the past 20 years are discussed and summarized in a proposed treatment flowchart.

To see or not to see – Ambiguous findings on post-mortem cross-sectional imaging in a case of ruptured abdominal aortic aneurysm

We present a case of a ruptured abdominal aortic aneurysm (AAA) with ambiguous accessory findings on post-mortem computed-tomography (PMCT), post-mortem magnetic resonance (PMMR) imaging, and PMCT-angiography (PMCTA) suggestive of thoracic aortic dissection. The diagnosis of ruptured AAA was confirmed by autopsy; however, there was no aortic dissection. The imaging findings that mimicked the presence of aortic dissection might have been an atypical presentation of post-mortem clotting or sedimentation. This case is an ideal example to illustrate benefits, limitations, and challenges of post-mortem cross-sectional imaging. It serves as a reminder that both, training as well as correlation of imaging findings with autopsy are fundamental to improve our understanding of radiologic findings on post-mortem cross-sectional imaging.
