Rare association of aneurysm of anterior mitral leaflet with bicuspid aortic valve

Mitral valve aneurysm is defined as outpouching of the mitral valve which expands in systole and collapse in diastole. It was first reported in 1729 by Morand. Most of the cases have been described in the African population. It is rare in the Indian population. Its chief presentations are congestive heart failure, palpitations, arrhythmia, or in rare cases an embolic phenomenon. It can be diagnosed either by echocardiography or cardiac imaging (magnetic resonance imaging/computed tomography). It can either occur as an isolated defect or with other associated valvular abnormalities. Here, we present a case of a 40-year-old male who was referred for the evaluation of palpitation who on the investigation was found to have a bicuspid aortic valve with severe Aortic Regurgitation (AR) along with aneurysm in the anterior mitral leaflet causing severe mitral regurgitation. This case highlights the importance of keeping a submitral aneurysm as a differential diagnosis for mitral regurgitation and searching for other associated valvular defects which may affect the management and treatment outcomes.

Hoarseness as a Predictor for Pulmonary Arterial Aneurysm and Extrinsic Left Main Coronary Artery Compression in Patients with Severe Pulmonary Hypertension

OBJECTIVE

Pulmonary artery (PA) enlargement is a common finding in patients with severe pulmonary hypertension (PH) and may be associated with extrinsic compression of the left main coronary artery (LMCA-Co) and/or compression of the left recurrent laryngeal nerve resulting in hoarseness named as Ortner syndrome (OS). In this study, we evaluated the diagnostic impact of OS in predicting the PA aneurysm and significant LMCA-Co in patients with PH.

METHODS

Our study population comprised retrospectively evaluated 865 with PH confirmed with the right heart catheterization between 2006 and 2022. Patients underwent coronary angiography due to several indications, including the presence of a PA aneurysm on echocardiography, angina symptoms, or the incidental discovery of LMCA-Co on multidetector computed tomography. The LMCA-Co is defined as diameter stenosis ³ 50% in reference distal LMCA segment on two consecutive angiographic planes.

RESULTS

The LMCA-Co and hoarseness were documented in 3.8% and 4.3% of patients with PH, respectively. Increasing PA diameter was significantly associated with worse clinical, hemodynamic, laboratory, and echocardiographic parameters. The receiver operating curves revealed that the PA diameter >41 mm was cutoff for hoarseness (AUC: 0.834; sensitivity 69%, specificity 84%, and negative predictive value 98%), and PA diameter >35 mm was cutoff for LMCA-Co >50% (AUC: 0.794; sensitivity 89%, specificity 58 %, and negative predictive value 99%). An odds ratio of hoarseness for LMCA-Co was 83.3 (95% confidence interval; 36.5-190, P < 0.001) with 3.2% sensitivity, 98.7% specificity, and 59% positive and 98% negative predictive values.

CONCLUSION

In this study, a close relationship was found between the presence of hoarseness and the probability of extrinsic LMCA-Co by enlarged PA in patients with severe PH. Therefore, the risk of LMCA-Co should be taken into account in patients with PH suffering from hoarseness.

Intravascular Ultrasound-Guided Stent Implantation in the Left Main Coronary Artery Extrinsic Compression by Pulmonary Artery Aneurysm Due to Eisenmenger Syndrome

Pulmonary arterial hypertension (PAH) is a profoundly destructive condition marked by the gradual narrowing and restructuring of small pulmonary arteries, leading to a rise in pulmonary vascular resistance (PVR), causing right-sided heart failure and, ultimately, mortality. During more advanced stages of this disease, patients may present with rare manifestations of pulmonary artery aneurysm (PAA) which are exertional chest pain, and hoarseness. The left main coronary artery compression (LMCA-Co) has been an increasingly recognized and possibly life-threatening entity in patients with severe PAH. The lack of well-established decision-making strategies for the management of both PAA and LMCA-Co has been remained as an unsolved issue in this setting. In this report, we present a case of percutaneous intervention of LMCA-Co with the guidance of intracoronary imaging in a patient with patent ductus arteriosus-Eisenmenger syndrome. Percutaneous intervention with intravascular guidance appears to be a safe and effective option for relieving symptoms and achieving positive clinical outcomes in patients with LMCA-Co.

Giant right atrial aneurysm associated with persistent left cranial vena cava in a cat

A 10-month-old female spayed Scottish Fold was referred to cardiology for incidental radiographic cardiomegaly. Echocardiography was suspicious for a right atrial or right auricular aneurysm. The differential diagnosis also included peritoneal-pericardial diaphragmatic hernia, mass lesion (cyst, granuloma, or neoplasia), or cardiac malformation. A giant right atrial aneurysm associated with a persistent left cranial vena cava was subsequently confirmed with computed tomography.

Indications for a "Surgery-First" Approach for the Treatment of Lower Extremity Arterial Disease

BACKGROUND

In recent years, there has been a tendency toward an "endovascular-first" approach for the treatment for femoropopliteal arterial disease. The purpose of this study is to determine if there are patients that are better served with an initial femoropopliteal bypass (FPB) rather than an endovascular attempt at revascularization.

METHODS

A retrospective analysis of all patients undergoing FPB between June 2006 - December 2014 was performed. Our primary endpoint was primary graft patency, defined as patent using ultrasound or angiography without secondary intervention. Patients with <1-year follow-up were excluded. Univariate analysis of factors significant for 5-year patency was performed using χ2 tests for binary variables. A binary logistic regression analysis incorporating all factors identified as significant by univariate analysis was used to identify independent risk factors for 5-year patency. Event-free graft survival was evaluated using Kaplan-Meier models.

RESULTS

We identified 241 patients undergoing FPB on 272 limbs. FPB indication was disabling claudication in 95 limbs, chronic limb-threatening ischemia (CLTI) in 148, and popliteal aneurysm in 29. In total, 134 FPB were saphenous vein grafts (SVG), 126 were prosthetic grafts, 8 were arm vein grafts, and 4 were cadaveric/xenografts. There were 97 bypasses with primary patency at 5 or more years of follow-up. Grafts patent at 5 years by Kaplan-Meier analysis were more likely to have been performed for claudication or popliteal aneurysm (63% 5-year patency) as compared with CLTI (38%, P < 0.001). Statistically significant predictors (using log rank test) of patency over time were use of SVG (P = 0.015), surgical indication of claudication or popliteal aneurysm (P < 0.001), Caucasian race (P = 0.019) and no history of COPD (P = 0.026). Multivariable regression analysis confirmed these 4 factors as significant independent predictors of 5-year patency. Of note, there was no statistical correlation between FPB configuration (above or below knee anastomosis, in-situ versus reversed saphenous vein) and 5-year patency. There were 40 FPBs in Caucasian patients without a history of COPD receiving SVG for claudication or popliteal aneurysm that had a 92% estimated 5-year patency by Kaplan-Meier survival analysis.

CONCLUSIONS

Long-term primary patency that was substantial enough to consider open surgery as a first intervention was demonstrated in Caucasian patients without COPD, having good quality saphenous vein, and who underwent FPB for claudication or popliteal artery aneurysm.

Superficial temporal artery aneurysm with segmental arterial mediolysis: a case report

Segmental arterial mediolysis (SAM) is a rare non-arteriosclerotic and non-inflammatory vascular disease. Superficial temporal artery (STA) aneurysms are usually associated with trauma, surgery, and hair transplantation. Spontaneous aneurysms of the STA are uncommon, but an STA aneurysm caused by SAM is rare. We report a 70-year-old woman with a spontaneous aneurysm of the STA. The mass in the left parietal region was pulsatile and gradually enlarged in size without any history of head trauma. The mass was successfully removed by surgery and was proved histopathologically to be a true aneurysm with SAM.

Obstructive jaundice as a rare complication of multiple pancreaticoduodenal artery aneurysms due to median arcuate ligament syndrome: a case report and review of the literature

BACKGROUND

Obstructive jaundice has various causes, and one of the rarest is pancreaticoduodenal artery aneurysm (PDAA), which is often associated with celiac axis stenosis caused by median arcuate ligament syndrome (MALS).

CASE PRESENTATION

The patient was a 77-year-old Azeri woman who presented with progressive jaundice, vague abdominal pain, and abdominal distension from 6 months ago. The intra- and extrahepatic bile ducts were dilated, the liver's margin was slightly irregular, and the echogenicity of the liver was mildly heterogeneous in the initial ultrasound exam. A huge cystic mass with peripheral calcification and compressive effect on the common bile duct (CBD) was also seen near the pancreatic head, which was connected to the superior mesenteric artery (SMA) and had internal turbulent blood flow on color Doppler ultrasound. According to the computed tomography angiography (CTA) findings, the huge mass of the pancreatic head was diagnosed as a true aneurysm of the pancreaticoduodenal artery caused by MALS. Two similar smaller aneurysms were also present at the huge aneurysm's superior margin. Due to impending rupture signs in the huge aneurysm, the severe compression effect of this aneurysm on CBD, and the patient's family will surgery was chosen for the patient to resect the aneurysms, but unfortunately, the patient died on the first day after the operation due to hemorrhagic shock.

CONCLUSION

In unexpected obstructive jaundice due to a mass with vascular origin in the head of the pancreas, PDAA should be considered, and celiac trunk should be evaluated because the main reason for PDAA is celiac trunk stenosis or occlusion by atherosclerosis or MALS. The treatment method chosen (including transarterial embolization, open surgery, or combined method) depends on the patient's clinical status and radiological findings, but transarterial embolization would be safer and should be used as a first-line method.

Gastroduodenal artery pseudoaneurysm presenting with hyperamylasemia

We present the case of a 75-year-old male admitted due to severe epigastric pain. His medical history was remarkable for chronic alcohol abuse, diabetes mellitus type 2, arterial hypertension, dyslipidemia. At admission he was hemodynamically stable. The initial workup showed elevated amylase, and the abdominal ultrasound excluded gallstone disease, so the diagnosis of acute pancreatitis was assumed. Despite appropriate fluid therapy, the patient developed hemodynamic instability. No signs of GIB were detected. An urgent laboratory workup revealed a new onset anemia and liver tests, including hyperbilirrubinemia. He underwent an urgent abdominal computed tomography with contrast, which showed a bleeding gastroduodenal artery (pseudoaneurysm and a hematoma adjacent to the second part of the duodenum. The patient underwent coil embolization achieving hemostasis without complications. GAD (pseudo)aneurysm is rare, accounting for 1.5% of all visceral artery aneurysms. Our patient presented with elevated pancreatic and liver enzymes, a more unique and challenging presentation since another more common differential diagnosis should be considered. The aneurysm can cause extrinsic common bile duct and main pancreatic duct pressure, which could explain the raised liver tests. Gastroenterologists should be aware of this rare and life-threatening entity, especially among patients presenting with common findings such as elevated amylase, jaundice, or altered liver tests. Hemodynamic instability is the main clue unmasking this diagnosis.

Rare but life-threatening cause of massive haemoptysis in an adolscent with tuberculosis: Rasmussen's aneurysm

Rasmussen's aneurysm is a rare yet fatal cause of massive haemoptysis in pulmonary tuberculosis. Early identification and timely intervention are of utmost importance to reduce the associated mortality. A girl in early adolescence presented with persistent fever and massive haemoptysis who required intubation and was subsequently confirmed to have tuberculosis. CT pulmonary angiogram showed the presence of pseudoaneurysms in the left upper and lower lobes. The haemoptysis resolved following the embolisation of the culprit's vessel. Residual lung destruction was evident on CT after a 12-month course of antituberculosis therapy. Rasmussen's aneurysm is a significant vascular complication of cavitary tuberculosis and needs to be considered in patients presenting with massive haemoptysis.

Resection and double pericardial patch repair of a congenital aneurysm of the mitral-aortic intervalvular fibrosa

Mitral-aortic intervalvular fibrosa aneurysms and pseudoaneurysms are rare entities but can lead to different, unpredictable and sometime dramatic complications. We report the case of a young woman presenting a congenital form of this aneurysm. Given the clinical and symptomatological progression, surgical treatment is mandatory. After a transverse aortotomy, we resected the aneurysm. Performing a pulmonary arteriotomy allows adequate control of the left main coronary artery, adjacent to the lesion. We repaired the remaining cavity, not far from the left coronary aortic cusp, with a double patch of bovine pericardium.

Endovascular Management of Pediatric Traumatic Intracranial Pseudoaneurysms: A Systematic Review and Case Series

OBJECTIVE

This study aims to systematically review the management and outcomes of pediatric patients who develop intracranial pseudoaneurysm (IPA) following head trauma or iatrogenic injury.

METHODS

Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic literature review was performed. Additionally, a retrospective analysis was conducted on pediatric patients who underwent evaluation and endovascular treatment for IPA originating from head trauma or iatrogenic injury at a single institution.

RESULTS

Two hundred twenty-one articles in the original literature search. Fifty-one met inclusion criteria resulting in a total of 87 patients with 88 IPAs including our institution. Patients ranged in age from 0.5 months to 18 years. Parent vessel reconstruction was used as first-line treatment in 43 cases, parent vessel occlusion in 26, and direct aneurysm embolization (DAE) in 19. Intraoperative complications were observed in 3.00% of procedures. Complete aneurysm occlusion was achieved in 89.61% of cases. 85.54% of cases resulted in favorable clinical outcomes. The mortality rate after treatment was 3.61%. The DAE group had higher rates of aneurysm recurrence than other treatment strategies (P = 0.009). Patients with SAH had overall worse outcomes compared to patients who did not (P = 0.024). There were no differences in favorable clinical outcomes (P = 0.274) or complete aneurysm occlusion (P = 0.13) between primary treatment strategies.

CONCLUSIONS

IPAs were successfully obliterated, and favorable neurological outcomes were achieved at a high rate regardless of primary treatment strategy. DAE had a higher rate of recurrence than the other treatment groups. Each described treatment method in our review is safe and viable for the treatment of IPAs in pediatric patients.

Effectiveness of Lumbar Cerebrospinal Fluid Drain Among Patients With Aneurysmal Subarachnoid Hemorrhage: A Randomized Clinical Trial

Importance

After aneurysmal subarachnoid hemorrhage, the use of lumbar drains has been suggested to decrease the incidence of delayed cerebral ischemia and improve long-term outcome.

Objective

To determine the effectiveness of early lumbar cerebrospinal fluid drainage added to standard of care in patients after aneurysmal subarachnoid hemorrhage.

Design, Setting, and Participants

The EARLYDRAIN trial was a pragmatic, multicenter, parallel-group, open-label randomized clinical trial with blinded end point evaluation conducted at 19 centers in Germany, Switzerland, and Canada. The first patient entered January 31, 2011, and the last on January 24, 2016, after 307 randomizations. Follow-up was completed July 2016. Query and retrieval of data on missing items in the case report forms was completed in September 2020. A total of 20 randomizations were invalid, the main reason being lack of informed consent. No participants meeting all inclusion and exclusion criteria were excluded from the intention-to-treat analysis. Exclusion of patients was only performed in per-protocol sensitivity analysis. A total of 287 adult patients with acute aneurysmal subarachnoid hemorrhage of all clinical grades were analyzable. Aneurysm treatment with clipping or coiling was performed within 48 hours.

Intervention

A total of 144 patients were randomized to receive an additional lumbar drain after aneurysm treatment and 143 patients to standard of care only. Early lumbar drainage with 5 mL per hour was started within 72 hours of the subarachnoid hemorrhage.

Main Outcomes and Measures

Primary outcome was the rate of unfavorable outcome, defined as modified Rankin Scale score of 3 to 6 (range, 0 to 6), obtained by masked assessors 6 months after hemorrhage.

Results

Of 287 included patients, 197 (68.6%) were female, and the median (IQR) age was 55 (48-63) years. Lumbar drainage started at a median (IQR) of day 2 (1-2) after aneurysmal subarachnoid hemorrhage. At 6 months, 47 patients (32.6%) in the lumbar drain group and 64 patients (44.8%) in the standard of care group had an unfavorable neurological outcome (risk ratio, 0.73; 95% CI, 0.52 to 0.98; absolute risk difference, -0.12; 95% CI, -0.23 to -0.01; P = .04). Patients treated with a lumbar drain had fewer secondary infarctions at discharge (41 patients [28.5%] vs 57 patients [39.9%]; risk ratio, 0.71; 95% CI, 0.49 to 0.99; absolute risk difference, -0.11; 95% CI, -0.22 to 0; P = .04).

Conclusion and Relevance

In this trial, prophylactic lumbar drainage after aneurysmal subarachnoid hemorrhage lessened the burden of secondary infarction and decreased the rate of unfavorable outcome at 6 months. These findings support the use of lumbar drains after aneurysmal subarachnoid hemorrhage.

MULTIPLE-SESSION SUBTHRESHOLD MICROPULSE LASER THERAPY FOR EXUDATIVE PERIFOVEAL VASCULAR ANOMALOUS COMPLEX: A CASE REPORT

PURPOSE

To report a case of exudative perifoveal vascular anomalous complex treated with a 532-nm subthreshold micropulse laser unresponsive to intravitreal injections.

METHODS

A case report.

RESULTS

A 65-year-old woman presented with blurred vision in the left eye for 1 month. An isolated perifoveal aneurysm surrounded by retinal hemorrhages and hard exudates was revealed in fundus examination, and optical coherent tomography showed a round lesion with a hyperreflective wall, subretinal fluid, and an intraretinal cyst. She was diagnosed with exudative perifoveal vascular anomalous complex and received four intravitreal injections. However, her best-corrected visual acuity decreased, and an aneurysmal lesion with macular edema persisted for approximately 6 months. Three sessions of 532-nm subthreshold micropulse laser therapy around the aneurysm were applied because the intravitreal injection treatment was ineffective. Since the last session, macular edema disappeared, the involuted lesion remained substantially stable without recurrence, and her best-corrected visual acuity improved without visual field defect.

CONCLUSION

To our knowledge, this is the first report of a successful subthreshold micropulse laser treatment for an exudative perifoveal vascular anomalous complex lesion, and it could be a safe and effective method for the patient unresponsive to intravitreal injections.

[Digital artery pseudoaneurysm. Case report and systematic review of the literature]

INTRODUCTION

aneurysms are focal and permanent dilations of an artery; in pseudoaneurysms, the normal layers of the blood vessel are replaced by fibrous tissue. Due to their low incidence, as well as the diagnostic and therapeutic challenge they represent; our objective is to present the clinical case of a pseudoaneurysm of a digital artery of the hand and to carry out a systematic review of this pathology.

MATERIAL AND METHODS

literature search in Medline, using the terms "digital artery" and "aneurysm." Studies of vascular dilation pathology affecting the hand and fingers were incorporated. Studies with pathology of proximal involvement of the hand were excluded.

CASE PRESENTATION

a 79-year-old female patient who, after a sharp force trauma to the fifth finger of the left hand, develops a rapidly growing necrotic tumor. She had ultrasound and angiography that suggested hematoma. Surgical management was decided, during which it was observed that the tumor involved ulnar collateral digital artery of the fifth finger. The lesion and the arterial segment involved were resected. Post-surgical course without complications. The histopathological diagnosis of pseudoaneurysm of the lesion was confirmed.

DISCUSSION

traumatic etiology is the most frequent cause of digital aneurysms. Risk factors for pseudoaneurysms include sharp force trauma and alterations of the coagulation pathways, as in the case presented.

CONCLUSION

the pseudoaneurysm of a digital artery is a rare pathology with great variability of therapeutic management. Surgical resection of the lesion with vascular flow reconstruction is the recommended treatment.

Characteristics of ANCA-associated vasculitis with aneurysms: Case series and review of the literature

INTRODUCTION

ANCA-associated vasculitis (AAV) is an exceptional cause of small and large vascular aneurysms. Here, we present the phenotypic characteristics of patients with AAV associated with the presence of aneurysms.

METHODS

We conducted a retrospective multicenter study and a systematic review of the literature. Only AAV patients with positive ANCA results and > 1 aneurysm(s) were enrolled. Patients were recruited through a call of observations among the French Vasculitis Study Group (FVSG) and the French Internal Medicine Network. Patients with aneurysm rupture were compared to those without.

RESULTS

We enrolled 51 patients in the cohort, including 31 (67%) with granulomatosis with polyangiitis. The median Birmingham Vasculitis Activity Score was 18 [6-41]. A total of 92 aneurysms were noted, 74% of which involved medium-sized arteries, particularly the renal artery. During a follow-up of 24 [6-56] months, 22 (43%) patients experienced aneurysmal rupture, 91% of which involved medium-sized vessels. Patients with aneurysmal rupture showed significantly more pulmonary infiltrates and higher creatinine levels at baseline than patients without rupture. Initial treatments did not differ between the two groups. Ten (20%) patients died during the follow-up, including three from an aneurysmal rupture.

CONCLUSION

Aneurysms were more frequently observed in GPA patients and predominantly affected medium-sized vessels, especially the renal arteries. The risk of rupture was high and occurred in >40% of patients. Because of their increased mortality, further studies are required to better manage this subset of patients.

Management of a fusiform brachial artery aneurysm associated with birth trauma

Brachial artery aneurysms in children are rare. Surgical treatment is generally recommended.We present the case of a female toddler with a pulsatile swelling on the medial aspect of the right upper arm without history of recent trauma. Medical history revealed a traumatic birth with labour arrest. Postnatally diffuse trunk and arm haematomas as well as a temporary right arm discolouration were detected. Preoperative ultrasound revealed a true brachial artery aneurysm. A full-body MRI ruled out any accompanying lesions. Primary resection and end-to-end anastomosis were performed. Recovery was uneventful. 6-month and 12-month follow-up showed normal motor function and arterial patency; ultrasound also demonstrated harmonious growth of the anastomosed vessel segments.No other publication has associated birth trauma with brachial artery aneurysm yet. Correct diagnosis and prompt curative surgery are key to prevent severe complications. Further reports and data on long-term outcome are needed to optimise clinical management.

Frail Silk: Is the Hughes-Stovin Syndrome a Behçet Syndrome Subtype with Aneurysm-Involved Gene Variants?

Hughes-Stovin syndrome is a rare disease characterized by thrombophlebitis and multiple pulmonary and/or bronchial aneurysms. The etiology and pathogenesis of HSS are incompletely known. The current consensus is that vasculitis underlies the pathogenic process, and pulmonary thrombosis follows arterial wall inflammation. As such, Hughes-Stovin syndrome may belong to the vascular cluster with lung involvement of Behçet syndrome, although oral aphtae, arthritis, and uveitis are rarely found. Behçet syndrome is a multifactorial polygenic disease with genetic, epigenetic, environmental, and mostly immunological contributors. The different Behçet syndrome phenotypes are presumably based upon different genetic determinants involving more than one pathogenic pathway. Hughes-Stovin syndrome may have common pathways with fibromuscular dysplasias and other diseases evolving with vascular aneurysms. We describe a Hughes-Stovin syndrome case fulfilling the Behçet syndrome criteria. A MYLK variant of unknown significance was detected, along with other heterozygous mutations in genes that may impact angiogenesis pathways. We discuss the possible involvement of these genetic findings, as well as other potential common determinants of Behçet/Hughes-Stovin syndrome and aneurysms in vascular Behçet syndrome. Recent advances in diagnostic techniques, including genetic testing, could help diagnose a specific Behçet syndrome subtype and other associated conditions to personalize the disease management.

Issues in Medicine

Rasmussen aneurysms are abnormalities of the pulmonary arterial system caused by tuberculosis (TB). They are associated with a highmortality rate when they cause life-threatening haemoptysis. High TB-prevalence regions have a large burden of TB-related haemoptysisbut often limited resources. This series of 25 patients who presented with life-threatening haemoptysis from current and/or previous TBwere found to have abnormal pulmonary arteries on computed tomography pulmonary angiogram (CTPA), which were judged to belikely contributors to their bleeding, either in isolation or with concomitant abnormal bronchial or systemic vasculature. These patientsunderwent transcatheter placement of Amplatzer vascular plugs in the feeder pulmonary artery. Bronchial and systemic lesions wereaddressed separately as needed. Immediate technical success was achieved in all patients, but four of them experienced intraoperativehaemoptysis related to dislodgement of the occluding platelet plug by the high-pressure automatic injector and wire. At 48 hours after theprocedure, 18 (72%) remained haemoptysis-free. Six of these experienced recurrence within 1 year of their procedure. Pulmonary arteryplacement of an Amplatzer vascular plug is a feasible option for treating bleeding Rasmussen aneurysms, but should be part of a combinedapproach to addressing suspected culprit vascular lesions in all intrathoracic vascular systems.
