Isolated Third Nerve Cranial Palsy: Complication of Brain Aneurysm

This case report highlights a critical and emergent condition, isolated third nerve cranial palsy due to a brain aneurysm. It emphasizes the importance of differential diagnosis and attentiveness to the physical exam in an emergency setting. The detailed progression from initial symptoms and misinterpretation to final diagnosis offers valuable insight into the dangers of overlooking critical diagnoses. A bilobed intracranial aneurysm arising from the internal carotid artery (ICA) caused symptoms in this patient that could have been attributed to a less malignant etiology, such as a complex migraine. Overlooking the urgency of the situation and missing the diagnosis could have had a grave and irreversible outcome.

Mimicking aneurysm in a patient with chronic occlusion of the left middle cerebral artery

The chronic occlusion of intracranial arteries generally has no or mild clinical symptoms,and the clinical symptoms of acute cerebral artery occlusion are mostly manifested as severe cerebral infarction symptoms,which often make early diagnosis difficult,thus losing the best treatment opportunity.Once cerebral infarction occurs,the consequences are difficult to recover.This is also an important reason for the high misdiagnosis rate and mortality of this disease.In this paper,the characteristics of the disease were analyzed to provide clinical reference.

Advancements and challenges in neuroimaging for the diagnosis of intracranial aneurysms:Addressing false positive diagnoses and emerging techniques

Despite advancements in neuroimaging,false positive diagnoses of intracranial aneurysms remain a significant concern.This article examines the causes,prevalence,and implications of such false-positive diagnoses.We discuss how conditions like arterial occlusion with vascular stump formation and infundibular widening can mimic aneurysms,particularly in the anterior circulation.The article compares various imaging modalities,including computer tomography angiogram,magnetic resonance imaging/angiography,and digital subtraction angiogram,highlighting their strengths and limitations.We emphasize the im-portance of accurate differentiation to avoid unnecessary surgical interventions.The potential of emerging technologies,such as high-resolution vessel wall ima-ging and deep neural networks for automated detection,is explored as promising avenues for improving diagnostic accuracy.This manuscript underscores the need for continued research and clinical vigilance in the diagnosis of intracranial aneurysms.

Enhancing postoperative pain control by surgically-initiated rectus sheath block in abdominal aortic aneurysm open repair: A case report

BACKGROUND Abdominal aortic aneurysm(AAA)repair often involves significant postoperative pain,traditionally managed with systemic opioids,which can cause undesirable side effects.This case report explores the novel use of a surgically-initiated rectus sheath block with a catheter-over-needle assembly for pain management in AAA repair.CASE SUMMARY A 67-year-old female with hypertension and previous aortic dissection underwent elective open repair of an infrarenal AAA,which had grown from 3.4 cm to 4.3 cm over 14 months.A rectus sheath block was initiated surgically for postoperative pain control.The patient reported low pain scores and did not require systemic intravenous opioids,enabling early ambulation and discharge on postoperative day seven without complications.By preventing complications of systemic opi-oids,the method indicating a promising direction for postoperative pain management in major vascular surgeries.CONCLUSION Surgically-initiated rectus sheath block as a valuable tool for managing postoperative pain in AAA repair.

COMPLICATION ANALYSIS OF INTRACRANIAL ANEURYSM EMBOLIZATION WITH CONTROLLABLE COILS

Objective To explore the causes, prevention, and management of the complications during intra-cranial aneurysm embolization with controllable coils (mechanical detachable spiral, MDS; and Guglielmi detachable coil, GDC). Methods Retrospective review of 120 cases with 125 intracranial aneurysms embolized with con-trollable coils from March 1995 to July 1999 was conducted. The 20 accidents(in 18 cases) including aneurysm rupture, over-embolization, protrusion of coil end into the parent artery, and thrombosis of the parent artery were analyzed. Results Among the 20 accidents, there were 6 aneurysm ruptures, 6 over-embolizations (in 5 cases), 6 coil protrusions, and 2 thromboses (one was secondary to coil protrusion). The embolization-related mortality was 3.33% (4/120), the permanent neurological deficit was 1.67% (2/120), and the transitory neurological deficit was 3.33%(4/120). The occurrence and outcome of the complications were related to the embolizing technique, the pattern of aneurysm and its parent artery, the imperfection of embolic materials, and the observation and management during embolization. Conclusion Skilled embolizing technique, better understanding of the angio-anatomy of an aneurysm and its parent artery, correct judgement and management during embolization, and improvement of embolic materials are beneficial to the reduction of complications and to the melioration of the outcome of complications.

Huge extrahepatic portal vein aneurysm as a late complication of liver transplantation

A 60-year-old male underwent orthotopic liver trans- plantation because of hepatitis C virus related cirrhosis. After 12 d,the patient underwent re-transplantation due to primary graft non function.One year later the patient developed a thrombosis of the main portal vein needing a surgical revision.After 11 years the patient was operated on because of a clinical picture of intestinal occlusion.As an incidental finding,a large aneurysm of the main portal vein was diagnosed.The incidence of intra-and extrahepatic Portal vein aneurysms(PVAs) is not clear.To the best of our knowledge,only one case of intrahepatic PVA in a liver transplant has been reported in the literature.In addition,we have found no documented cases of extrahepatic PVAs in liver transplanted patients.

Successful management of hepatic artery pseudoaneurysm complicating chronic pancreatitis by stenting

A 41-year old alchoholic male with a history of chronic pancreatitis was admitted for nausea, vomiting and weight loss. Angiogram was performed and demonstrated an aneurysmal sac with a narrow neck originating from the inferior aspect of the distal portion of the proper hepatic artery. The origin of the pseudoaneurysm was covered with a 5 mm × 2.5 cm Viabahn cover stent （Gore）. A repeat angiogram showed some leak and a second stent （6 mm × 2.3 cm） was deployed and overlapped with the first stent by 3 mm. Contrast was injected and a repeat angiogram demonstrated complete exclusion of the aneurysm. A repeat computerized axial tomography （CAT） scan of the abdomen after 24 h showed successful stenting. The patient had an uneventful post-operative course.

Splenic arteriovenous fistula and sudden onset of portal hypertension as complications of a ruptured splenic artery aneurysm: Successful treatment with transcatheter arterial embolization. A case study and review of the literature

Splenic arteriovenous fistula （SAVF） accounts for an unusual but well-documented treatable cause of portal hypertension. A case of a 50-year-old multiparous female who developed suddenly portal hypertension due to SAVF formation is presented. The patient suffered from repeated episodes of haematemesis and melaena during the past twelve days and thus was emergently admitted to hospital for management. Clinical and laboratory investigations established the diagnosis of portal hypertension in the absence of liver parenchymal disease. Endoscopy revealed multiple esophageal bleeding varices. Abdominal computed tomography （CT） and transfemoral celiac arteriography documented the presence of a tortuous and aneurysmatic splenic artery and premature filling of an enlarged splenic vein, findings highly suggestive of an SAVF. The aforementioned vascular abnormality was successfully treated with percutaneous transcatheter embolization. Neither recurrence nor other complications were observed.

A complicated case of innominate and right common arterial aneurysms due to Takayasu’s arteritis

BACKGROUND Innominate artery aneurysms (IAAs) are relatively rare. Endovascular therapy has been an alternative to open surgery in some IAA cases, but open repair is still necessary in complicated cases. CASE SUMMARY We report a 35-year-old female who suffered from Takayasu’s arteritis. The patient did not get regular treatment, and IAA and right common carotid artery aneurysm developed, which complicated with occlusion of the left carotid artery, subclavian artery, and the initial part of the left vertebral artery. The patient also had moderate aortic valve insufficiency. With inflammation being controlled well, the patient received the surgery for arterial aneurysms of innominate and right common carotid arteries and aortic valve insufficiency. The shunts for cerebral blood supply were designed to protect the brain and the surgery was conducted successfully under extracorporeal circulation. CONCLUSION The case illustrates that open surgery may be appropriate for some complicated IAAs, and brain protection is important.

Safety and efficacy of complete versus near-complete coiling in treatment of intracranial aneurysms

Objective:This study aimed to evaluate the clinical and angiographic outcomes of aneurysms that were completely or near-completely embolized and ascertain whether complete embolization is important in the stent-assisted coiling(SAC)of intracranial aneurysms.Methods:This retrospective study enrolled 390 patients(417 aneurysms).Among them,complete(100%)or nearcomplete(>90%)angiographic obliteration of the aneurysms on immediate angiography was accomplished.Baseline characteristics,complications,angiography follow-up results,and clinical outcomes were analyzed.Results:Cumulative adverse events occurred in 30 patients(7.7%),including thromboembolic complications in 17(4.4%),intraoperative rupture in 10(2.6%),and others in 3(0.8%).Statistical analyses revealed an increased intraprocedural rupture rate in the initial completely occluded aneurysms(5.6%compared with 1.0%).The incidence of cumulative adverse events was higher in patients with completely occluded aneurysms(11.1%)than in those with near-completely occluded aneurysms(5.5%).Angiography follow-up was available for 173 aneurysms.Aneurysm occlusion status at follow-up was correlated with stent placement(p?0.000,odds ratio?5.847),size(p?0.000,odds ratio?6.446 for tiny aneurysms;and p?0.001,odds ratio?5.616 for small aneurysms),and initial aneurysm occlusion status(p?0.001,odds ratio?3.436).Complete occlusion at followup was seen in 82.6%of the initial complete occlusion group versus 63.0%of the initial near-complete occlusion group.The incidence of complete occlusion at follow-up was higher in the initial completely occluded aneurysms with SAC(100%)than in the initial completely occluded aneurysms with non-SAC(65.2%).Conclusions:Initial complete treatment may lead to higher complication rates and good clinical outcomes at follow-up.Stent placement may enhance progressive aneurysm occlusion.Initial complete occlusion with SAC can provide durable closure at follow-up.

Follow-up of endovascular aortic aneurysm repair:Preliminary validation of digital tomosynthesis and contrast enhanced ultrasound in detection of medium- to long-term complications

AIM: To validate the feasibility of digital tomosynthesis of the abdomen(DTA) combined with contrast enhanced ultrasound(CEUS) in assessing complications after endovascular aortic aneurysm repair(EVAR) by using computed tomography angiography(CTA) as the gold standard.METHODS: For this prospective study we enrolled 163 patients(123 men; mean age, 65.7 years) referred for CTA for EVAR follow-up. CTA, DTA and CEUS were performed at 1 and 12 mo in all patients, with a maximum time interval of 2 d.RESULTS: Among 163 patients 33 presented complications at CTA. DTA and CTA correlated for the presence of complications in 32/33(96.96%) patients and for the absence of complications in 127/130(97.69%) patients; the sensitivity, specificity, positive predictive value(PPV), negative predictive value(NPV) and accuracy of DTA were 97%, 98%, 91%, 99%, and 98%, respectively. CEUS and CTA correlated for the presence of complications in 19/33(57.57%) patients and for the absence of complications in 129/130(99.23%) patients; the sensitivity, specificity, PPV, NPV and accuracy of CEUS were 58%, 99%, 95%, 90%, and 91%, respectively. Sensitivity, specificity and accuracy of combining DTA and CEUS together in detecting EVAR complications were 77%, 98% and 95%, respectively.CONCLUSION: Combining DTA and CEUS in EVAR follow-up has the potential to limit the use of CTA only in doubtful cases.

An Extraordinary Case of Silent Extensive Anterior Wall Myocardial Infarction Complicated with Giant Left Ventricular Aneurysm and Dressler Syndrome

Early post-acute myocardial infarction (AMI) pericarditis, pericardial effusion with or without cardiac tamponade, and late post-MI pericarditis (Dressler syndrome), are the major pericardial complications after AMI. It is quite rare and estimated to be only about 0.1% in AMI patients according to a recent report, so it is easily neglected or misdiagnosed and may have tragic result to patient. Clinical features of this post-AMI complication include fever, chest pain, pericarditis and pleurisy occurring 2 to 3 weeks after AMI. Dressler syndrome is rarely associated with left ventricular aneurysm. Contrast enhanced magnetic resonance and echocardiography play important roles in diagnosis of left ventricle aneurysm. We report a 54-year-old male heavy labor worker who had asymptomatic, severe coronary artery disease, complicated with silent myocardial infarction, which resulted in large left ventricular aneurysm, and also systolic heart failure was noted. Patient was diagnosed to have Dressler syndrome after his second cardiology clinic follow-up. He received coronary angiography which revealed triple vessel disease with total occlusion of left anterior descending artery, and a giant left ventricular aneurysm was found. He received surgical intervention with Batista method and followed-up uneventfully at the cardiology clinic.

Operative strategy of complex internal carotid arteryposterior communicating artery aneurysms Defensive effect on perioperative nerve injury

BACKGROUND： The two problems in treating intracranial aneurysm are the vascular reconstruction and brain protection, especially for complex internal carotid artery-posterior communicating artery （ICA-PComA） aneurysms. OBJECTIVE： To analyze the anatomic features and operative technique of complex ICA-PComA aneurysms, and investigate how to better protect the brain tissue. DESIGN： A retrospective case analysis. SETTING： Department ofNeurosurgery, Dalian Central Hospital. PARTICIPANTS： Totally 154 inpatients with ICA-PComA aneurysms were selected from the Department of Neurosurgery, Dalian Central Hospital from January 1998 to December 2006, including 19 cases （12.3%） of complex ICA-PComA aneurysms, 8 males and ll females, 38 -67 years of age. Informed contents for surgery and observation were obtained from all the patients or their relatives. METHODS： The clinical manifestations, including initial symptoms and Hunt＆Hess grading, were observed. Corresponding strategies were selected for different types of ICA-PComA aneurysms. The patients were followed up at 3 months postoperatively. According to the results of Glasgow scoring, the curative effects were classified as good （4 - 5 points）, bad （2 - 3 points） and dead （1 point）. The results at discharge were taken as early results, whereas the follow-up results as late results. MAIN OUTCOME MEASURES： Clinical manifestations and curative effects of the patients. RESULTS： All the 19 patients with ICA-PComA were involved in the analysis of results. For clinical manifestations, the initial symptoms were subarachnoid hemorrhage （n =15）, paralysis of oculomotor nerve （n =3）, and occasional attack （n =1）; The Hunt＆Hess grading was grade Ⅰ in 4 cases, grade Ⅱ in 6 cases, grade Ⅲ in 6 cases, grade Ⅳ in 2 eases, and grade Ⅴ in 1 ease. The curative effects were that aneurysm breakage and bleeding occurred in 6 cases perioperatively, uncomplete clipping of aneurysm in 2 cases and constriction of parent artery in 1 case. The complications were nervous and ischemic ones. The early outcome was good in 12 eases and bad in 7 cases, no one died. The late outcome was good in 17 cases and bad in 2 eases. CONCLUSION： Complex ICA-PComA aneurysm is a particular aneurysm, thus different operative strategies should be adopted according to the conditions to improve the operative outcome and reduce ischemic and nervous injuries.

Idiopathic cystic artery aneurysm complicated with hemobilia and acute pancreatitis

BACKGROUND:Aneurysm of the cystic artery is no common,and it is a rare cause of hemobilia.Most o reported cases are pseudoaneurysms resulting from eithe an inflammatory process in the abdomen or abdomina trauma. METHOD:We report a healthy individual who developed hemobilia and acute pancreatitis associated with cysti artery aneurysm. RESULT:The patient was managed with angio-embolization with an uneventful post-embolization course. CONCLUSIONS:Visceral artery aneurysms are rare and can rupture with potentially grave outcome due to excessive bleeding.Angiographic embolization as a common method of treatment for visceral artery aneurysms was used in ou patient with good outcome.

Total Thrombosis of Bifurcated Endoprosthesis: A Rare Complication of Endovascular Treatment of Abdominal Aortic Aneurysm

Background: Aortic stents are a therapeutic alternative to open surgery of abdominal aortic aneurysms. We report a case of treatment of an abdominal aortic aneurysm with a bifurcated stent, complicated by total thrombosis. Aim: The purpose of this presentation was to understand the causes, mechanisms, incidents and accidents that contributed to this complication. Case Presentation: A 48-year-old man patient with a history of high blood pressure, ischemic heart disease, chronic obstructive pulmonary disease, who was found during a surveillance check-up, an infra-renal abdominal aorta aneurysm measured at 56 mm in diameter, asymptomatic but progressive. The indication of an endovascular treatment by the placement of a bifurcated prosthesis was posed and accepted. Thrombosis of the two limbs was intra-operative, upper-end migration without endoleak at 4 months postoperative, total thrombosis of the stent at 13 months postoperatively. Explantation of the stent followed by aortobi-iliac bypass was finally performed in the 15th month. Conclusion: The cardiopulmonary antecedents, the anatomical and evolutionary characteristics of the aneurysm could have played a role in the occurrence of the complications observed in this patient.

Extensive complex thoracoabdominal aortic aneurysm salvaged by surgical graft providing landing zone for endovascular graft:A case report

BACKGROUND Surgical repair of complex abdominal aortic aneurysm is associated with a higher perioperative mortality and morbidity.The advent of endovascular aortic repair(EVAR)has reduced perioperative complications,although the utilization of such techniques is limited by lesion characteristics,such as involvement of the visceral or renal arteries(RA)and/or presence of a sealing zone.CASE SUMMARY A 60-year-old male presented with a Crawford type IV complex thoracoabdominal aortic aneurysm(CAAA)starting directly distal to the diaphragm extending to both common iliac arteries(CIAs).The CAAA consist of a proximal and distal aneurysmal sac separated by a 1 cm-healthy zone in the infrarenal level.Due to the poor performance of the patient and the expansive disease,we planned a stepwise-combined surgery and EVAR to minimize invasiveness.A branched graft was implanted after surgical debranching of the visceral and RA.Since the patient had renal and liver injury after surgery,the second stage EVAR was performed 10 mo later.The stent graft was implanted from the distal portion of surgical branched graft to both CIAs during EVAR.The patient has been uneventful for 5-years after discharge and is being followed in the outpatient clinic.CONCLUSION The current case demonstrates that the surgical graft can provide a landing zone for second stage EVAR to avoid aggressive surgery in patients with poor performance with a long hostile CAAA.

Unruptured Right Sinus of Valsalva Aneurysm Dissecting into Interventricular Septum Causing Complete Heart Block: Can Early Surgical Correction Revert Rhythm Disturbances?

A sinus of Valsalva aneurysm (SOVA) is abnormal dilatation of the either aortic sinuses, area of the aortic root between the aortic valve annulus and the sinotubular junction. Their clinical presentation may range from being asymptomatic as an incidental finding on cardiac imaging to symptomatic presentations related to the compression of adjoining structures or intracardiac shunting caused by rupture of the SOVA mostly into the right side of the heart. The compression leads to findings of tricuspid valve regurgitation, right ventricular outflow tract (RVOT) obstruction and rarely complete heart block (CHB). Dissection or erosion into interventricular septum is one of the rarest complications of SOVA. The symptomatic presentation is almost always a surgical emergency. Here we present a case report of a patient with unruptured sinus of valsalva originating from right sinus dissecting into interventricular septum causing complete heart bock. In this case after surgical correction the complete heart block reverted to sinus rhythm.

Complications, imaging results, and midterm clinical outcomes of pipeline embolisation device in the treatment of cerebral aneurysms

Background: The introduction of pipeline embolisation device (PED) has improved the feasibility of endovascular treatment of intracranial aneurysms. The device allows for endoluminal reconstruction across the aneurysm neck but is permeable enough that flow is preserved across the pressure gradients into sidebranch arteries. In spite of higher rates of aneurysm occlusion, there is lack of data concerning medium to long-term clinical and imaging results. Methods: This study was a prospective single center analysis of complications, imaging results, and medium term clinical outcomes after PED treatment of intracranial aneurysms. We included cases over a 17-month period in a tertiary interventional neuroradiology center. We collected data on demographics, vascular risk factors, clinical presentation, angiographic results post treatment, angiographic follow-up and clinical follow-up. Results: Thirty-three patients were included, 25 females and 8 males, with mean age of 55 years;3 presented with acute subarachnoid hemorrhage and 30 for elective treatment. Thirty-seven aneurysms were treated: 35 Internal Carotid Artery (ICA), 1 basilar trunk fusiform, and 1 vertebral artery intradural dissecting aneurysms. No deaths have occurred. Five patients suffered transient neurological complications (15%). Overall aneurysm occlusion was demonstrated in 85% of patients at the end of one year. Discussion:?Overall, the technique of flow diversion and endoluminal reconstruction differs greatly from the established endosaccular packing techniques of standard coiling, balloon remodeling, or stent assisted coiling. Our midterm follow-up confirms that, the rates of clinically significant complications compare favorably with published data on stent assisted coiling, potentially making these devices a truly revolutionizing technique.

Vasospasm as a Complication after Aneurysmal Rupture and Its Relation with Surgical Clipping and Endovascular Coiling among a Georgian Sample

Background: Potentially lethal, aneurysmal subarachnoid hemorrhage has a bad prognosis for many individuals. Over the past few decades, endovascular and surgical interventions have been developed, including surgical clipping, and endovascular coiling. Patients who have aSAH are also susceptible to delayed cerebral ischemia and cerebral vasospasm. The aim of this study is to compare the outcome of endovascular coiling with surgical clipping in patients with SAH, specifically in relation to prevalence of vasospasm, in the country of Georgia. Method: In this study, we present a retrospective review of the outcomes of 217 patients with acute subarachnoid hemorrhage who underwent endovascular coiling or surgical clipping. The data were gathered from patients who are admitted to New Vision University Hospital and Caucasus Medical Center in Tbilisi, Georgia, between 2017 and 2022. Results: Vasospasm was prevalent in 217 of the patients who had aneurysmal rupture when they first appeared. Endovascular coiling or surgical clipping was used to treat aneurysmal rupture. In our sample, 24.81 percent of patients who underwent coiling experienced vasospasm after 14 days, compared to 31.25 percent of patients who underwent clipping. After endovascular coiling and surgical clipping, the severity of vasospasm was only slightly different, according to Lindegaard ratios. Finally, 32 patients (23.35 percent) died after coiling whereas 55 patients (68.75 percent) died within three decades of clipping. Conclusion: After 5 years of data collection, this study has demonstrated the most favorable option for treatment is endovascular coiling. However, the treatment choice takes multiple factors into account, and clipping is not ideal for some ruptured aneurysms. Despite the fact that endovascular coiling is usually successful and minimally invasive, complications can occur and additional monitoring and potential surgical intervention are indicated.
