Bifurcation dissecting aneurysm: tips and tricks to differentiate from saccular aneurysm.

Bifurcations are a common site for saccular aneurysms, but rarely can be a site for dissecting aneurysms. Identification of these aneurysms is extremely important because the management plan depends on it. We describe a rare case of a ruptured dissecting aneurysm at the right ICA bifurcation in a pre-teen child which posed a diagnostic dilemma but ultimately was successfully managed with flow diversion.

Anesthetic management for cesarean section in two parturient with ascending aortic aneurysm: a case-based discussion.

BACKGROUND: The anesthetic management of parturients with ascending aortic aneurysm for cesarean section can be particularly challenging, primarily because of increased risk for aortic dissection or aneurysm rupture. CASE PRESENTATION: We present some aspects of the anesthetic management of two parturients with ascending aortic aneurysm for cesarean sections; amongst, the use of remifentanil with its effects on patient and newborn. We emphasize the importance of a cardio-obstetric team in the context of preoperative planning of such patients. Also, we reviewed some literature on the anesthetic management with its effect on peri-operative hemodynamic stability. CONCLUSION: Maintaining hemodynamic stability is paramount in the prevention of the rupture or dissection of ascending aortic aneurysm during labor of parturient.

Right Sinus of Valsalva Aneurysm Rupturing into the Right Atrium and Dissecting into the Interventricular Septum.

The right sinus of the Valsalva aneurysm (SVA) rupturing into the right atrium (RA) and dissecting into the interventricular septum (IVS) is rare. The disease can be definitively diagnosed using two-dimensional (2D) echocardiography and color Doppler ultrasonography. Real-time biplane imaging and three-dimensional (3D) echocardiography offer new perspectives for viewing and diagnosing this disease.

Cerebral revascularization for complex vertebrobasilar artery dissecting aneurysms.

Vertebrobasilar artery dissecting aneurysms (VBDAs) are the most surgically challenging type of aneurysm. Cerebral revascularization is the ultimate treatment for complex VBDAs. We retrospectively analysed the characteristics, surgical outcomes and follow-up data of 21 patients who underwent cerebral revascularization to treat complex VBDAs from 2015 to 2022. According to the location of the aneurysm and the anatomic relationship between the VBDA and the PICA, VBDA patients were classified into four groups: aneurysms located at the VA with PICA involvement (10 patients), aneurysms located at the VA without PICA involvement (1 patient), aneurysms located at the basilar apex segment (1 patient) and aneurysms located at the basilar trunk segment (9 patients). A surgical algorithm for complex VBDAs was determined primarily by the location of the aneurysm, the status of the aneurysm and the ability of retrograde blood flow to reach the proximal vertebrobasilar artery. Surgical modalities for patients with aneurysms in the VA with PICA involvement included low-flow (OA-PICA) bypasses with aneurysm trapping, aneurysm excision or reconstructive clip in 8 patients and STA-PCA bypass combined with PICA preservation and aneurysm trapping in 2 patients. In patients with aneurysms in the VA without PICA involvement, aneurysm excision was performed without cerebral bypass. In patients with aneurysms in the basilar apex segment, high-flow bypass (ECA-RA-P2) with aneurysm trapping was performed. In patients with aneurysms in the basilar trunk segment, surgical modalities included high-flow bypasses (ECA-RA-P2 and LVA-RA-P2) with aneurysm trapping or proximal occlusion in 6 patients, ECA-RA-P2 bypass with partial proximal occlusion in 1 patient, ECA-RA-P2 bypass alone in 1 patient, and STA-PCA bypass with R-VA narrowing in 1 patient. Of the 21 patients, 20 experienced clinical improvement or no change, and 17 of 21 patients achieved favourable functional outcomes (mRS ≤ 2). However, one patient died of infarction and respiratory failure postoperatively. Aneurysms were completely obliterated in 13 patients, shrank in 5 patients and stabilized in 2 patients. The median follow-up period was 32.5 months. During the follow-up period, all bypasses were patent, and further clinical improvement was observed in 11 patients. Cerebral revascularization appears to be safe and effective for the treatment of complex VBDAs, and cerebral revascularization could act as a complementary treatment strategy.

Invasive treatment for extracranial carotid artery aneurysm: a single-center case series and literature review.

BACKGROUND: Extracranial carotid artery aneurysm (ECAA) is a rare peripheral arterial disease. The main treatment strategies include conservative treatment, open surgery, endovascular treatment, and hybrid techniques, and there is no expert consensus or guidelines, with only a few case reports. METHOD: This article reviewed 10 cases diagnosed with "extracranial carotid artery aneurysm" and received invasive treatment from January 2013 to July 2023 in our medical center. RESULTS: There were 10 patients with ECAA admitted to our center, including seven cases of true aneurysms, two cases of pseudoaneurysms, and one case of dissecting aneurysm. There were 3 females and 7 males aged between 24-61 years. Based on the characteristics of ECAA, we designed the individualized procedure including open surgery, endovascular treatment, and hybrid treatment. Procedures were technically successful for all patients, and none of them had any adverse events during the follow-up period except for one patient who developed cerebral hemorrhage on the third postoperative day and recovered after cerebral puncture and drainage. CONCLUSION: The current invasive treatments for ECAA mainly include open surgery, endovascular treatment, and hybrid treatment, and they all appear to be safe and effective.

Symptomatic Vasospasm Refractory to Clazosentan after Subarachnoid Hemorrhage of Ruptured Vertebral Artery Dissecting Aneurysm: Clinical Implications from Two Contrasting Cases.

Clazosentan prevents vasospasms after aneurysmal subarachnoid hemorrhage (SAH). However, clinical data on patients with SAH with ruptured vertebral artery dissecting aneurysms (VADAs) are limited. We report the case of a 49-year-old male patient with mild-grade (WFNS grade 1) thick and diffuse (modified Fisher grade 3) SAH who underwent endovascular trapping of a ruptured VADA, resulting in a poor functional outcome with a modified Rankin Scale score of 4 due to severe symptomatic vasospasm refractory to clazosentan, requiring repeated rescue endovascular therapies and chronic communicating hydrocephalus. A retrospective analysis of the clot density in the basal and Sylvian cisterns, assessed by the Hounsfield unit (HU) values of serial CT scans, in this patient showed persistent higher values, distinct from another VADA case that showed a decline in HU values with a good clinical course. These results imply the limited effectiveness of clazosentan in cases of thick and diffuse SAH after a ruptured VADA, even in good-clinical-grade patients treated with less invasive modalities. The HU values may become a simple quantitative marker for predicting symptomatic vasospasms and chronic hydrocephalus.

Spontaneous triple vessel cervicocephalic artery dissection in a young gentleman: A case report.

INTRODUCTION: Cervicocephalic arterial dissections (CADs) occur in 3 cases per 100,000 individuals across all ages. Multiple simultaneous CADs are found in 13 to 22% of cases, and three or more dissections occur in approximately 2%. CADs might result from multifactorial intrinsic deficiencies of vessel wall integrity and extrinsic factors, e.g., minor trauma. CASE PRESENTATION: A young gentleman presented to the emergency department with a sudden onset of a spinning sensation of surrounding, left side arm weakness, blurring of vision, and an NIHSS score of 4. An urgent CT scan of the head and intracranial angiogram showed bilateral severe stenosis of the distal cervical segment of internal carotid arteries (ICAs) and right vertebral artery moderate stenosis at the V2 segment. He had been given IV TPA (Alteplase) within the 4.5-hour window. After 4 hours, the patient's GCS dropped from 15 to 10, and the NIHSS score increased from 4 to 24, followed by witnessed a generalized tonic-clonic seizure. Repeat urgent CT head showed no evidence of intracerebral hemorrhage (ICH). The patient was arranged for cerebral angiographic catheterization that showed bilateral flame-shaped occlusion of cervical ICA dissection. There is a mild focal narrowing of the right cervical vertebral artery, likely dissection. Routine laboratory blood workup for vasculitis was negative. During MICU admission, he had witnessed the right arm hemichorea-ballism spectrum abnormal movement. After the 6th-month follow-up, intracranial CT angiogram showed reduced caliber of the bilateral distal cervical course of the internal carotid arteries seen with residual dissection and focal outpouching of the right ICA representing pseudoaneurysm. DISCUSSION: The occurrence of multiple CADs suggests the presence of an underlying intrinsic arteriopathy, such as FMD, the presence of pseudoaneurysm, environmental triggers, cervical manipulation, and remote history of head or neck surgery. A study of the most extensive case series of patients with cervical artery dissection showed 15.2% of patients with multiple CAD. In most patients with multiple cervical artery dissections, antithrombotic treatment is effective, complete recanalization, and the outcome is favorable. Outside the window period of acute ischemic stroke, either anticoagulation or antiplatelet therapy is a recognized treatment for secondary ischemic stroke prevention due to extracranial artery dissection. For acute stroke or TIA patients caused by intracranial artery dissection, experts recommend antiplatelet therapy rather than anticoagulation. CONCLUSION: Simultaneous triple-vessel cervicocephalic arterial dissections are rarely reported condition. Multiple CADs are associated with underlying vasculopathy and environmental triggers, and a majority are recanalized with antithrombotic treatment with favorable outcomes. Antithrombotic treatment is effective in most patients with multiple CADs, and most expect complete recanalization. This case report guides physicians in the treatment and outcome of acute stroke due to multiple CAD.

Multiple intracranial enlarging dissecting aneurysms: a case report.

BACKGROUND: Cases of multiple cerebral aneurysms are rare. In this case report, we describe a male patient with multiple, enlarging, and ruptured aneurysms. The two aneurysms were believed to be dissecting aneurysms. CASE DESCRIPTION: A 47-year-old man presented with left limb paralysis. Magnetic resonance imaging revealed a cerebral infarction. Digital subtraction angiography (DSA) identified an aneurysm and occlusion in the right middle cerebral artery (MCA). The MCA aneurysm was remarkably enlarged on the eighth day after cerebral ischemia and was treated using endovascular techniques. Two weeks after the endovascular treatment, the patient experienced a severe headache and became comatose, and a subarachnoid re-hemorrhage was confirmed. The fourth DSA revealed an enlarging dissecting aneurysm in the posterior cerebral artery. The patient died without further treatment. CONCLUSION: Some dissecting aneurysms rapidly enlarge and rupture.

Efficacy and predicting factors of multimodal treatment for ruptured intracranial vertebral artery dissecting aneurysms.

We aimed to investigate the efficacy of our multimodal strategies and propose a treatment algorithm for ruptured vertebral artery dissecting aneurysms (VADAs). This study included 41 patients treated at a single institution between 2015 and 2022. The treatment modalities were justified based on the collateral circulation and aneurysm location related to the posterior inferior cerebellar artery (PICA). Treatment outcomes and complications of each treatment group were analyzed. The association between the collateral blood flow and the postoperative vertebrobasilar ischemia (VBI) was also investigated. There were 17 post-PICA, 10 PICA-involved, 7 pre-PICA, and 7 non-PICA types. Reconstruction techniques included flow diversion devices (n = 11) and stent-assisted coiling (n = 3). Deconstruction techniques included coil trapping (n=17) and microsurgical parent artery occlusion with (n = 8) or without PICA revascularization (n = 2). Five (18.5%) of the deconstruction group had postoperative VBI. Overall favorable outcomes in both groups were observed in 70.7% of patients with a mean follow-up time of 21.5 months. Poor World Federation of Neurosurgical Societies grade (IV-V) was identified as a predictor of unfavorable outcomes (p = 0.003). In addition, the VA4/BA4 ratio > 0.22, the presence of collateral blood flow from the posterior communicating artery (PcomA), and a contralateral VA diameter > 2.5 mm were associated with a lower risk of postoperative VBI. In summary, the proposed strategic treatment in this study is pragmatic, yielding satisfactory results where a deconstructive technique should be used with caution, particularly when there is a flow mismatch or the absence of collateral PcomA in the vertebrobasilar circulation.

Diagnosis of fast-growing thoracic aneurysm with microscopic evidence of dissection over 6 months follow-up in an asymptomatic middle aged gentleman: a case report.

BACKGROUND: Thoracic aortic aneurysm (TAA), is a pathological dilatation of the aortic segment with the tendency to expand, dissect or rupture, and risk of mortality. The progression rate is mainly slow. As the risk of rupture increases with the size of the aortic diameter, it is important to diagnose TAA appropriately to prevent mortality. CASE PRESENTATION: Here, we present a case with a fast-growing TAA, complicated by subclinical dissection in a middle-aged gentleman, associated with non-compaction left ventricle, diagnosed 6 months after the first diagnosis of this co-occurrence, successfully managed by an uneventful surgical procedure. The pathological examination was the key to the diagnosis of this concealed phenomenon, i.e. a fast-growing aortic aneurysm complicated by subclinical dissection. CONCLUSION: This case report emphasizes the importance of close follow-up of patients with fast-growing TAA for considering remote possibility of this silent life-threatening disease; subclinical dissecting aneurysm, especially in patients with other cardiac comorbidities. Although imaging modalities can help accurate diagnosis, in cases with fast-growing TAA, we should not wait for imaging signs of dissection and/or rupture.

The optimal management of ruptured basilar artery dissecting aneurysms: a case series and scoping review.

The natural history of ruptured basilar artery dissecting aneurysms (BADAs) remains unclear compared to that of ruptured vertebral artery dissecting aneurysms (VADAs). In this study, we investigated the natural history and optimal management of ruptured BADAs. We identified 17 patients with ruptured BADA among 4586 patients with aneurysmal subarachnoid hemorrhage (SAH) treated in seven participating hospitals. A scoping literature review was undertaken to investigate prognostic factors. Six patients among the profiled patients (35.3%) died, all with poor SAH grades (World Federation of Neurological Societies Grade IV and V). Rebleeding after admission was observed in three patients (17.6%) with poor SAH grades. Aggressive treatment and conservative management were initiated in seven and ten patients, respectively. Patients with good SAH grades had significantly higher favorable treatment outcomes than those with poor grades (83.3% vs. 9.1%, P = 0.005). Moreover, based on a scoping review of 158 cases with ruptured BADA, including the patients from our series, approximately 90% of patients with good SAH grades had favorable outcomes. A good SAH grade and no rebleeding after admission were favorable prognostic factors (P < 0.0001 and P = 0.002, respectively). The rebleeding rates were 20.2%, 13.3%, and 6.3% for dilated, pearl and string, and stenotic lesions, respectively. We concluded that the natural history of isolated ruptured BADAs may be better than that of VADAs. Although definitive treatment, if possible, is undoubtedly important, conservative management with careful radiological follow-up for morphological changes might be a viable option for patients in good clinical condition and with non-dilated lesions.

Flow diverter for the treatment of large (> 10 mm) vertebral artery dissecting aneurysms.

OBJECTIVE: To evaluate the outcomes of flow-diverting device (FDD) treatment for large vertebral artery dissecting aneurysms (VADAs). METHODS: This retrospective study evaluated 12 patients with 12 VADAs who were treated using FDD between 2013 and 2020. Clinical and radiographic data, including procedure-related complications and clinical outcomes assessed using the modified Rankin Scale (mRS) at the time of the last follow-up, were collected and reviewed. RESULTS: All 12 patients had unruptured aneurysms. There were 3 (25%) female and 9 (75%) male patients, and the mean patient age was 54.6 years. The mean size of the aneurysm was 15.9 ± 4.8 mm. The mean follow-up duration was 15.8 months. Single FDD without additional coils was used in all patients. One patient underwent second-line treatment with FDD for recurrence of large VADA after stent-assisted coiling. Immediate follow-up angiography after placement of the FDD demonstrated intra-aneurysmal contrast stasis. There were 2 (17%) patients who had peri-procedural stroke. Angiography at the 6-month follow-up in 10 patients showed favorable occlusion (OKM grade C3 + D). A total of 11 (92%) patients had good clinical outcome (modified Rankin Scale ≤ 2) at the last follow-up. No re-treatment or delayed aneurysm rupture occurred during the follow-up period. CONCLUSIONS: Reconstructive technique with FDD is a feasible and effective modality for the treatment of large VADAs, showing favorable occlusion rate and clinical outcome.

Overlapping Pure LIVS Jr. Stents for Isolated Ruptured Dissecting Aneurysm of the Proximal Posterior Inferior Cerebellar Artery.

We report our experience in treating a ruptured dissecting posterior inferior cerebellar artery (PICA) aneurysm. To our knowledge, this is the first reported case of overlapping stenting without coils for a ruptured dissecting aneurysm of the proximal PICA. A 66-year-old male patient presented with sudden altered mental state and a subarachnoid hemorrhage (SAH). The cerebral angiography revealed a long segmental dissecting aneurysm on proximal PICA. Overlapping stents were deployed to the dissecting site, and angiogram showed intact distal PICA flow and decreased contrast staining in the dissecting site. Successful flow diversion was achieved with stents. Procedure-associated complications did not occur. The patient's postoperative course was uneventful. In follow-up cerebral angiography, dissecting aneurysm achieved complete remodeling. The decision that led to the choice of treatment is discussed.

Stent graft placement guided by intravascular ultrasound for subclavian artery dissecting aneurysm.

Subclavian artery dissecting aneurysm is relatively rare and can be caused by traumatic, nontraumatic, and iatrogenic etiologies. Surgical management of subclavian artery dissecting aneurysm has been sparsely reported. Recently, due advances in endovascular techniques making them less invasive, these approaches have become more standard as treatments. Subclavian artery dissecting aneurysm management usually depends on whether there is ischemia of the tissues supplied by the subclavian artery. Furthermore, treatment strategies depend on which section of the artery is involved. In particular, treatment is difficult if the dissecting aneurysm has branching vessels. In this case report, we show that endovascular repair using a covered stent graft is a promising approach to repair a subclavian artery dissecting aneurysm. In this case, the stent graft was highly effective, and follow-up examinations showed good patency of the subclavian artery. Additional use of IVUS (Volcano Inc.; Rancho Cordova, CA, USA) is helpful to obtain the precise location of the true lumen of a dissecting aneurysm.

Long-term fate of aortic branches in patients with aortic dissection.

OBJECTIVE: Late morbidity and mortality related to aortic branches in patients with aortic dissection (AD) have not been well described. We investigated the fate of aortic branches in a population cohort of patients with newly diagnosed AD. METHODS: We used the Rochester Epidemiology Project record linkage system to identify all Olmsted County, Minnesota, residents with a diagnosis of AD from 1995 to 2015. Only patients with >30 days of available follow-up imaging studies were included in the present analysis. The primary outcome was freedom from any branch-related event (any intervention, aneurysm, malperfusion, rupture, or death occurring after the acute phase >14 days). The secondary outcome was the diameter change in the aortic branches. Univariate and multivariable Cox proportional hazards models were used to identify the predictors of branch-related events. Univariate and multivariate linear regression models were used to assess the aortic branch growth rate. RESULTS: Of 77 total incident AD cases, 58 patients who had survived and had imaging follow-up studies available were included, 28 (48%) with type A and 30 (52%) with type B AD. The presentation was acute in 39 patients (67%), 6 (10%) of whom had had branch malperfusion. Of 177 aortic branches involved by the AD, 81 (46%) had arisen from the true lumen, 33 (19%) from the false lumen, and 63 (36%) from both. After the acute phase, freedom from any branch-related event at 15 years was 48% (95% confidence interval [CI], 32%-70%). A total of 31 branch-related events had occurred in 19 patients within 15 years, including 12 interventions (76% freedom; 95% CI, 63%-92%), 10 aneurysms (67% freedom; 95% CI, 50%-90%), 8 cases of malperfusion (76% freedom; 95% CI, 61%-94%), and 1 rupture (94% freedom; 95% CI, 84%-100%). No branch-related deaths had occurred. Type B AD (hazard ratio [HR], 3.5; 95% CI, 1.1-10.8; P = .033), patency of the aortic false lumen (HR, 6.8; 95% CI, 1.1-42.2; P = .038), and malperfusion syndrome at presentation (HR, 6.0; 95% CI, 1.3-28.6; P = .023) were predictors of late aortic branch-related events. The overall growth rate of aortic branches was 1.3 ± 3.0 mm annually. Patency of the aortic false lumen, initial branch diameter, and Marfan syndrome were significantly associated with diameter increase. CONCLUSIONS: In patients with AD, aortic branch involvement was responsible for significant long-term morbidity, without any related mortality. Type B AD, patency of the aortic false lumen, and malperfusion syndrome at presentation resulted in a greater risk of branch events during the long-term follow-up. Dilatation of the aortic branches was observed in one third of cases during follow-up, especially in the case of a patent aortic false lumen or the presence of Marfan syndrome.

Treating a thrombotic giant dissecting renal artery aneurysm through ex-vivo vascular reconstructive surgery followed by kidney reimplantation.

Renal artery aneurysms, although rare, may give rise to complications both per se (due to the risk of thrombosis and subsequent wall rupture) and by impairment of the renal function (due to extrinsic compression and high blood pressure). We describe a paucisymptomatic young patient with acute thrombosis of a massive dissecting renal artery aneurysm, for which the successful treatment was performed through ex-vivo vascular surgery followed by autotransplantation of the reconstructed kidney. The aneurysm was described through abdominal echography, computed tomography angiography, and transfemoral transcatheter arterial angiography. It originated from an atypical branch emerging at 90 degrees from the left renal artery. After a short branching off, it degenerated into a dissected aneurysmal sac as large as half a kidney (outer diameter of 60 mm), compressing the lower pole of the left kidney and delaying the lower half nephrogram. Ex-vivo surgical exclusion of the aneurysm was successfully performed. The kidney was reimplanted in the left iliac fossa (termino-lateral anastomosis between the renal artery and external left iliac artery, termino-terminal ureteric anastomosis) with excellent postoperative outcomes. For most asymptomatic aneurysms, expectant treatment is a reasonable approach. However, interventional or surgical repair is indicated in certain circumstances depending on the size of the aneurysm and its natural history, rupture risk, and interventional/surgical risks. The renovascular hypertension, dissecting and thrombotic events, its giant size, the young fertile age, and the presence of the flank pain were all indicative of the need for aneurysm exclusion in our case.

Complete Aortic Endovascular Repair.

Patients unfit for open repair after development a postdissection aortic arch and thoraco-abdominal aneurysm after open ascending aortic replacement for type A dissection would have no other treatment options. We report the case of a 75-year-old man with a type A aortic dissection treated by ascending aortic replacement. The patient presented an enlargement of the downstream aorta and thoraco-abdominal aneurysm 6-months after. This patient underwent a three-stage surgical sessions, open surgery for extraanatomical supra-aortic trunks reconstruction, endovascular branched treatment of ascending, arch and descending aorta and another one to perform an endovascular fenestrated reconstruction of thoraco-abdominal and infrarenal aorta.

A dissecting aneurysm of the sinus of Valsalva involving the inter-ventricsular septum in a patient with syphilis and a quadricuspid aortic valve.

Aneurysms of the sinus of Valsalva are rare, with dissecting aneurysms of the sinus of Valsalva that extend into the inter-ventricular septum being even more rare. This report describes a young patient with syphilis and a quadricuspid aortic valve who experienced a spontaneously dissecting aneurysm of the sinus of Valsalva and the basal inter-ventricular septum.

Risk factors for medullary infarction after endovascular trapping of vertebral artery dissecting aneurysms.

Internal trapping (IT) is a treatment option for intracranial vertebral artery dissecting aneurysms (VADAs). Medullary infarction (MI) is a complication linked to this treatment. This study aims to clarify the outcomes of IT for VADAs and the risk factors for MIs. We retrospectively reviewed the databases from 2010 to 2017 to identify patients with VADAs treated by IT at seven collaborating institutions. Radiological findings, clinical courses, and outcomes were analyzed. Perforating arteries were classified into terminal or longitudinal types using preoperative angiography. IT was completed in 90 patients (74 ruptured and 16 unruptured VADA). Postoperative rebleeding did not occur in any ruptured VADA patients. Postoperative MRI detected MIs in 26 patients (28.9%). The incidence of MIs in the ruptured VADA (32%) was higher compared with that in the unruptured VADA (13%), though it was not significant. In the MI group, the occlusion or blind alley of the terminal-type and longitudinal-type perforator was confirmed in 23 patients (88%) and 11 patients (42%), respectively. The occlusion or blind alley of the terminal-type perforator was an independent risk factor for MIs in the logistic regression analysis (OR 5.81; 95% CI 1.34-25.11; p = 0.018). In ruptured VADA, postoperative MI (OR 12.2; 95% CI 3.19-64.55; p = 0.0001) and high-grade SAH (OR 8.02; 95% CI 2.32-37.70; p = 0.0006) were independent risk factors of an unfavorable clinical outcome. In conclusion, MIs were an independent risk factor for unfavorable outcomes after IT, especially for a ruptured VADA. The occlusion or blind alley of the terminal-type perforator caused by the IT was associated with postoperative MIs.

Multimodal imaging of a rare interventricular septum dissecting aneurysm: A case report.

We report the case of a patient who presented with chest pain and palpitation, and in whom multimodality imaging, including transthoracic echocardiography, computer tomography angiogram, and coronary angiogram led to the diagnosis of interventricular septum dissecting aneurysm resulting from the rupture of a sinus of Valsalva aneurysm and paravalvular aortic root pseudoaneurysm. The patient underwent the modified Cabrol procedure in the cardiac surgery department. His ruptured sinus of Valsalva aneurysm was repaired and its communication with the pseudoaneurysm was closed. This case report highlights the role of multimodality cardiac imaging.
