Surgical treatment of a rare brachial artery aneurysm postarteriovenous fistula closure after kidney transplant:A case report

BACKGROUND Brachial artery aneurysms are defined as dilations greater than 50%of the normal diameter,which are rare among all peripheral arterial aneurysms.While they are often present as pseudoaneurysms,true brachial artery aneurysms are also detected rarely.In this case report,the surgical repair method of true brachial artery aneurysms,which is a rare condition,is explained.CASE SUMMARY Herein,we present a 61-year-old male patient with complaints of swelling and pain in the right arm antecubital region that had been progressing over 6 mo.Upon the diagnosis of a true brachial artery aneurysm associated with arteriovenous fistula,the aneurysm was surgically repaired with an autologous saphenous vein graft.The patient was discharged without any neurovascular complications postoperatively.CONCLUSION True brachial artery aneurysms are rare and there are not any recommendations for their management in the current literature.Even though the treatment of true aneurysms in this artery is primarily based on a surgical treatment,endovascular repair also might be an option.

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.

Surgical Treatment of Poor Grade Middle Cerebral Artery Aneurysms Associated with Large Sylvian Hematomas Following Prophylactic Hinged Craniectomy

The clinical characteristics of patients who presented in poor clinical grade due to ruptured middle cerebral artery aneurysms （MCAAs） associated with large sylvian hematomas （SylH） were ana- lyzed and an ingenious designed prophylactic hinged craniectomy was introduced. Twenty-eight pa- tients were graded into Hunt-Hess grades IV-V and emergency standard micro-neurosurgeries （aneu- rysm clipping, hematoma evacuation and prophylactic hinged craniectomy） were performed, and their clinical data were retrospectively analyzed. 46.43% of the patients reached encouraged favorable out- comes on discharge. The favorable outcome group and the poor outcome group significantly differed in terms of patients＇ anisocoria, Hunt-Hess grade before surgery, extent of the midline shift and time to the surgery after bleeding （P〈0.05）. There were no significant differences in age, sex, volume and location of the hematoma, size of aneurysm between the favorable and poor groups （P〉0.05）. However, ingen- ious designed prophylactic hinged craniectomy efficiently reduced the patients＇ intracranial pressure （ICP） after surgery. It was suggested that preoperative conditions such as Hunt-Hess grading, extent of the midline shift and the occurrence of cerebral hernia affect the prognosis of patients, but time to the surgery after bleeding and prophylactic hinged craniectomy are of significant importance for optimizing the prognosis ofMCAA oatients 19resenting with large SylH.

Impact of Intraoperative Blood Pressure Control and Temporary Parent Artery Blocking on Prognosis in Cerebral Aneurysms Surgery

Objective In cerebral aneurysm clipping and embolization, blood pressure control and temporaryparent artery blocking are common methods to prevent aneurysm rupture. Their influence on the prognosis isuncertain. In this study, we try to find out the association between methods above and prognostic indicators.

Applications of multislice CT angiography in the surgical clipping and endovascular coiling of intracranial aneurysms

Prompt diagnosis and therapy of aneurysms are critical for patients with nontraumatic subarachnoid hemorrhage （SAH）.The aim of our study was to assess the clinical usefulness of multislice computed tomography angiography （CTA） in the surgical and endovascular treatment of intracranial aneurysms.A total of 195 cases with 206 intracranial aneurysms underwent CTA.Fifty （24%） aneurysms underwent surgical clipping while 156 （76%） aneurysms underwent endovascular coiling.In the five missed aneurysms at digital substraction angiography and the nine aneurysms with mass intracerebral hematomas,surgical treatment was successfully performed based on 16-slice CTA alone,and the other 36 aneurysms were clipped on the main basis of the CTA.The intraoperative findings correlated well with the CTA findings and all aneurysms were clipped successfully.Sixteen-slice CTA image information has been shown to determine the choice of aneurysm therapy and assist the surgical and endovascular treatment of intracranial aneurysms.

Dynamic interaction nursing intervention on functional rehabilitation and self-care ability of patients after aneurysm surgery

BACKGROUND Nursing practices based on the dynamic interaction model have been shown to be superior to generic nursing practices.However,whether this model is effective in patients recovering from intracranial aneurysm surgery is not well studied.AIM To investigate the effect of nursing based on a dynamic interaction model on functional rehabilitation of patients after aneurysm surgery.METHODS A total of 86 cases in our hospital with intracranial aneurysm from April 2019 to April 2021,were selected and divided into the study group and the control group,with 43 patients in each group.The control group received routine nursing,and the research group received nursing intervention based on a dynamic interaction model.The daily living ability(activities of daily living,ADL),cognitive function(Simple Intelligent Mental State Scale,MMSE),quality of life(Generic Quality of Life Inventory-74,GQOL-74),self-care ability(Exercise of Self-Care Agency scale),incidence of complications,and nursing satisfaction were recorded before and after intervention.RESULTS Before intervention,ADL(52.09±6.44),MMSE(18.03±4.11),and GQOL-74(53.68±4.34)scores in the study group were not significantly different from those in the control group(ADL:50.97±7.32,MMSE:17.59±3.82,GQOL-74:55.06±3.98)(P>0.05).After intervention,ADL(86.12±5.07),MMSE(26.64±2.66),and GQOL-74(83.13±5.67)scores in the study group were higher than those in the control group(ADL:79.81±6.35,MMSE:24.51±3.00,and GQOL-74:77.96±6.27)(P<0.05).Before intervention,self-concept(17.46±4.44),self-care skills(25.22±4.20),self-care knowledge(22.35±4.74),and self-care responsibility(15.06±3.29)scores in the study group was similar to those in the control group(self-concept:16.89±5.53,self-care skills:24.59±4.46,self-care knowledge:21.80±3.61,and self-care responsibility:14.83±3.11)(P>0.05).After the intervention,self-concept(26.01±3.18),self-care skills(37.68±6.05),self-care knowledge(45.56±5.83),and self-care responsibility(22.01±3.77)scores in the study group were higher than those in the control group(self-concept:22.97±3.46,self-care skills:33.02±5.65,selfcare skills knowledge:36.81±5.54,and self-care responsibility:17.97±3.56 points)(P<0.05).The incidence of complications in the study group(4.65%)was lower than that in the control group(18.60%)(P<0.05).Nursing satisfaction in the study group(95.35%)was higher than that in the control group(81.40%)(P<0.05).CONCLUSION Nursing intervention based on a dynamic interaction model can improve postoperative cognitive function,daily living ability,self-care ability,quality of life,and patient satisfaction,while reducing the risk of complications.

Diagnosis and surgical treatment of giant splenic artery aneurysms with portal hypertension; report of 4 cases

BACKGROUND:Giant splenic artery aneurysm (GSAA) is a rare but clinically relevant disease. Its importance lies in potential rupture and hemorrhage. Early diagnosis and treatment before rupture of GSAA are crucial to GSAA pa- tients especially to GSAA patients with portal hypertension (PHT). METHODS: Four patients of GSAA with PHT treated at our hospital from December 1999 to September 2001 were retrospectively reviewed. RESULTS: GSAA was found in all patients with digital sub- stracted angiography ( DSA) and/or magnetic resonance angiography (MRA) before operation. Resection of GSAA and treatment of PHT were carried out successfully with no perioperative mortality. CONCLUSIONS: Patients with GSAA are apt to have PHT or segmental PHT because of suppression of the splenic vein or formation of aneurysm-portal vein fistula. Opera- tion should be focused on GSAA, and PHT complica- tions.

Surgical resection of rare internal jugular vein aneurysm in neurofibromatosis type 1

Neurofibromatosis type 1 is a congenital condition affecting neurons and connective tissue integrity including vasculature.On extremely rare occasions these patients present with venous aneurysms affecting the internal jugular vein.If they become large enough there presents a risk of rupture,thrombosis,embolization or compression of adjacent structures.In these circumstances,or when the patient becomes symptomatic,surgical exploration is warranted.We present a case of one of the largest aneurysms in the literature and one of only five associated with Neurofibromatosis type 1.A 63-year-old female who initially presented for a Hinchey Ⅲ diverticulitis requiring laparotomy developed an incidentally discovered left neck swelling prior to discharge.After nonspecific clinical exam findings,imaging identified a thrombosed internal jugular vein aneurysm.Due to the risks associated with the particularly large size of our patient's aneurysm,our patient underwent surgical exploration with ligation and excision.Although several techniques have been reported,for similar presentations,we recommend this technique.

Surgical Treatment of Aortic Aneurysm and Aortic Dissection:A Retrospective Analysis of 122 Cases

The study summarizes the clinical experience of surgical treatments of various types of thoracic aneurysm and aortic dissection. Clinical data of 122 patients with thoracic aneurysm and aortic dissection during July 2005 to July 2008 were retrospectively analyzed. The elective operations were performed in 107 patients while emergency surgery was done in 15 cases. Different surgical strategies were employed on the basis of diseased region, including simple ascending aortic replacement （n=3）, aortic root replacement （n=43）, hemi-arch replacement/total arch replacement ＋ elephant trunk technique （n=32）, thoracic/thoracoabdominal aortic replacement （n=8） and endovascular repair （n=36）. In this series, there is 4 cases of perioperative death due to massive cerebral hemorrhage （n=1）, respiratory failure （n=1） and multiple organ dysfunction syndrome （MODS） （n=2）. Three cases developed post-operative massive cerebral infarction and the relatives of the patients abandoned treatment. Instant success rate of endovascular repair was 100%. The intimal rupture was sealed. Blood flow was unobstructed in true lumen and no false lumen was visualized. It was concluded that aggressive surgery should be considered in the patients with thoracic aneurysm and aortic dissection. Surgical procedures should vary with the location and the nature of the lesions.

Extrahepatic portal vein aneurysm: Two case reports of surgical intervention

We report two cases of extrahepatic portal vein aneurysm,and both of them underwent surgical intervention. The first case had a mild pain in right upper quadrant of the abdomen; the second had no obvious symptoms. Physical examination revealed nothing abnormal. Both of them were diagnosed by magnetic resonance imaging angiography (MRA). One of the aneurysms was located at the main portal vein, the other, at the confluence of the superior mesenteric vein and the splenic vein, and these two places are exactly the most common locations of the extrahepatic portal vein aneurysm reported in the literature (30.7% each site). The first case underwent aneurysmorrhaphy and the second case, aneurysm resection with splenectomy. Both of them recovered soon after the operation, and the symptom of the first case was greatly alleviated. During the follow-up of half a year, no complication and adverse effect of surgical intervention was found and the color Doppler ultrasonography revealed no recurrence of the aneurysmal dilation. We suggest that surgical intervention can alleviate the symptom of the extrahepatic portal vein aneurysm and prevent its complications effectively and safely for low risk patients.

Outcomes of early physiotherapy in patients with cerebral aneurysms treated by surgical clipping or endovascular embolization

Early physiotherapy was given to 124 patients with ruptured or unruptured cerebral aneurysms who were treated by surgical clipping or endovascular embolization.Patients were divided into four groups according to their Hunt and Hess grade at admission and aneurysm treatment modality： Group 1,Hunt and Hess grade≤II and surgical clipping;Group 2,Hunt and Hess grade≤II and endovascular embolization;Group 3,Hunt and Hess grade≥III and surgical clipping;Group 4,Hunt and Hess grade≥III and endovascular embolization.Level of consciousness was evaluated using the Glasgow Coma Scale,functional status using the Glasgow Outcome Scale,level of the mobility using the Mobility Scale for acute stroke patients,and independence in activities of daily living using the Barthel Index.After early physiotherapy,the level of consciousness and functional status improved significantly in Groups 1,3,and 4;mobility improved significantly in all groups;and independence in activities of daily living improved significantly in Groups 1 and 3.At discharge, Groups 1 and 2 had better functional status than Groups 3 and 4.Level of consciousness,functional status,mobility and independence in activities of daily living improved after early physiotherapy. These findings suggest that early physiotherapy improved the prognosis of patients with cerebral aneurysms who were treated by surgical clipping or endovascular embolization.Patients with a worse clinical status at presentation had a poorer functional status at discharge.The outcome of physiotherapy was not affected by whether surgical clipping or endovascular embolization was chosen for treatment of the aneurysm.

EXPERIENCE ON SURGICAL MANAGEMENT OF RUPTURE OF ABDOMINAL AORTIC ANEURYSM

Objective. To describe our surgical experience on rupture of abdominal aortic aneurysm .Methods. Two cases of ruptured aortic aneurysms with severe complication were analyzed. Aorta reconstruction procedures were performed using bifurcated e-PTFE grafts during emergency operation. Diagnosis, preoperadve resuscitation, emergency surgical intervention, and postoperative complications of these patients were summarized and discussed.Results. Rupture of aortic aneurysm in both patients presented as a huge retroperitoneum haematoma by computed tomography scan. They were successfully saved by prompt body fluid compensation, emergency procedure, intraoperative resuscitation, and postoperative intensive care.Conclusions. Correct diagnosis, prompt surgical management, immediate intraoperative proximal aorta clamping during procedure, and effective management of postoperative complications were the key points to successful treatment of ruptured aortic aneurysm.

Significance of Cold Renal Perfusion on Renal Function and Clinical Outcomes When Renal Ischemia Time Exceeded 30 Min during Pararenal and Juxtarenal Abdominal Aortic Aneurysm Surgery

Objectives: To investigate the influence of cold renal perfusion on renal function and clinical outcomes in cases where the renal ischemia time exceeded 30 min during pararenal and juxtarenal abdominal aortic aneurysm (P/JAAA) surgery. Methods and Results: Fifty-four patients who underwent open repair for P/JAAAs were retrospectively analyzed. Thirty-nine patients received renal perfusion with cold Ringer’s solution (perfusion group) and 15 patients did not receive renal perfusion (non-perfusion group). There were no significant differences in preoperative serum creatinine level (Cr) (1.08 ± 0.42 vs. 1.35 ± 0.71 mg/dL, p = 0.09), percentage of patients with Cr > 2 mg/dL [2/38 (5%) vs. 2/15 (13%), p = 0.8], and renal ischemia time during proximal aortic clamping (49 ± 21 vs. 47 ± 11 min;p = 0.8) between the groups. Postoperative Cr was significantly lower in the perfusion group than in the non-perfusion group (1.48 ± 0.76 vs. 2.23 ± 1.21 mg/dL, p < 0.01). The percentage of patients with postoperative Cr > 2 mg/dL was also significantly lower in the perfusion group than in the non-perfusion group [5 (13%) vs. 7 (47%), p < 0.01)]. At discharge, Cr returned to preoperative levels in both groups. All patients were discharged from the hospital without incidents. Conclusion: Renal artery perfusion with cold Ringer’s solution clearly reduced the deterioration of postoperative renal function compared to non-renal perfusion.

Surgical repair of thoracoabdominal aortic aneurysms using the critical artery reattachment technique

In the study, we sought to retrospectively analyze the effectiveness and safety of surgical repair of thoracoab-dominal aortic aneurysm using the critical artery reattachment technique. Twenty-three consecutive thoracoab-dominal aortic aneurysm patients were treated using the technique of sequential aortic clamping and critical artery reattachment. The entire procedure was technically successful in all patients. One died of renal failure and the overall hospital mortality was 4.35%. The total incidence of complications was 21.74%. At a median follow-up of 33 months, all patients were alive. We found that the application of critical artery reattachment technique in the management of thoracoabdominal aortic aneurysm provides excellent short- and mid-term results in most patients. It could markedly increase the curing rate and reduce the morbidity of postoperative complications including par-aplegia, ischemia of abdominal viscera, and renal failure.

Celiac Artery Aneurysm Due to Chronic Spontaneous Dissection: Two Cases of Surgical Repair

In this report, we describe two surgical cases of celiac artery aneurysm due to chronic and asymptomatic spontaneous dissection without atherosclerotic change or medial degeneration. Case 1 had replacement of the celiac and common hepatic arteries using a knitted Dacron prosthetic graft, and case 2 had simple aneurysmectomy. The incidence of celiac artery dissection is increasing lately, but subsequent aneurysm is relatively rare. Our two cases had no atherosclerotic risk factors, so it might be possible that celiac artery aneurysm due to spontaneous dissection may produce different findings from dissection of other arteries. We consider that the need for surgery should be determined carefully if the asymptomatic celiac artery aneurysm due to dissection is small and unless it shows any changes in its diameter in the follow-up period.

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.

Open surgical approach for two coincidental splenic artery aneurysms:a case report

Several factors can contribute to the formation of aneurysms,including hemodynamic changes,polyarteritis nodosa,bacterial endocarditis,vasculitis,fibromuscular dysplasia,vascular malformation,and cystic medial necrosis.^([1,2]) Surgery is recommended for splenic artery aneurysms (SAAs) greater than 25 mm in diameter,and several surgical approaches are used,including open surgery,laparoscopic surgery,and percutaneous embolization.Laparoscopic surgery might be associated with an increased risk of pancreatic leakage compared to the open surgery approach.

Atherosclerotic Descending Aortic Aneurysms. Pros and Cons of Surgery

Within the last few years, there has been a strong trend to rethink the issue of management of atherosclerotic descending thoracic and abdominal aortic aneurysms (AAAs). When etiopathogenetic associations among changes observed during the progression of the disease were not fully described, surgeons had successfully applied, although traumatic, but a rather radical method to rescue from the rupture threat. As we gained experience and knowledge about long-term outcomes, mostly concerned mortality, we realized that surgery could not be the main tactical approach to AAAs treatment due to its frequent inefficiency and failure to guarantee that the disease would be suppressed including co-morbidities, polymorphic processes and clinical manifestations. It all required more sparing treatment strategies. The situation gave rise to a more argumentative and sparing medical-and-surgical approach to treatment based on a more in-depth understanding of the etiopathogenesis of the disease whereas surgery would remain of prime importance when appropriate. The following has been developed to improve treatment outcomes for AAA: 1) Multifactorial determination of indications for surgical correction with outlining the area of relative and absolute risk of aneurysm rupture;2) Method of conservative treatment aimed to attain and maintain optimal blood pressure, target levels of cholesterol and low-density lipoproteins, as well as reduce oxidative and inflammatory processes in aorta, strengthen its wall, stabilize the disease and control co-morbidities. A four-year follow-up of patients using this developed technology has yielded more preferred results suggesting the need for narrowing indications for surgery to treat AAAs. Another advantage of the sparing approach to treat AAA is economic, due to fewer operations and implantations of stent-grafts, considering the fact that medical treatment should be used in operated subjects, too.

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.
