Repair of a right coronary artery rupture with perforated right ventricle following spontaneous pseudoaneurysm: a case report.

BACKGROUND: Following the rupture of a coronary artery, a patient's condition usually deteriorates rapidly due to cardiac tamponade. A pseudoaneurysm due to a coronary artery rupture is rare; however, when a spontaneous coronary artery pseudoaneurysm occurs without tamponade, it creates a fistula in the right ventricle, often requiring surgical repair. CASE PRESENTATION: This report describes the case of a 68-year-old man who presented with chest discomfort after a 12-day course of antibiotic treatment for bacteremia. Following coronary angiography, echocardiography, and enhanced computed tomography, he was diagnosed with a right coronary artery pseudoaneurysm accompanied with perforation of the right ventricle. Severe adhesions were observed during emergency surgery surrounding the entire heart. The patient presented with risk factors for coronary artery disease, including hypertension and smoking history. His coronary artery was severely calcified due to end-stage renal failure requiring dialysis; thus, a covered stent could not fit inside the arterial lumen. Consequently, coronary artery bypass grafting to the right coronary artery and right ventricle repair were performed. Unfortunately, the patient died postoperatively due to sepsis from intestinal translocation. This rare development was hypothesized to be an incidental result of the combination of severe post-inflammatory adhesions, extensive coronary artery calcification, and rupture of the calcification crevices. CONCLUSIONS: In the case of a severe post-inflammatory response, shock without cardiac tamponade may require further scrutiny by assuming the possibility of inward rupture. For patients in poor condition, two-stage surgical treatment might be considered after stabilization with a covered stent.

When Ascites Is Not Ascites!

Patients presenting with ascites should be properly evaluated to differentiate potential etiologies. Then, based on the evaluation, we can tailor more accurate treatment plans for patients. Cirrhosis is the most common cause, and others include cancer, heart failure, and, in our case, rarely a visceral artery rupture. Rupture of the splenic artery aneurysm can be lethal and should be considered as a possible differential in a patient with no previous history of heart failure, cancer, or cirrhosis. Our patient was identified after an initial misdiagnosis of possible ascites secondary to cirrhosis. However, input from an interventional radiologist led to proper identification and tailored management. Early treatment is crucial to prevent complications, including death.

Internal carotid artery rupture during endovascular thrombectomy in patients with tandem occlusion: A two-case report.

Endovascular thrombectomy in patients with tandem occlusions can rarely result in the rupture of the internal carotid artery, leading to subarachnoid haemorrhage and death. However, this complication and its causes are rarely reported and discussed in the literature. We describe two cases of internal carotid artery rupture during endovascular thrombectomy in patients with tandem occlusion. It is hypothesised that the primary approach to the distal lesion, before recanalization, creates a blind alley that faces an intraluminal pressure increase upon manual contrast injection, surpassing the vessel's resistance and resulting in arterial wall rupture. To prevent this complication, approaches such as treating the proximal occlusion first, injecting the contrast through a microcatheter or retracting the endovascular support catheter proximally to the stenosis of the cervical internal carotid artery have been suggested and are discussed.

Spontaneous Hemoperitoneum Due to Ruptured Uterine Artery: A Rare Complication During Pregnancy.

Spontaneous rupture of the uterine artery is a rare and life-threatening cause of hemoperitoneum in pregnancy, associated with high maternal and perinatal morbidity and mortality. We present a case of a 29-year-old woman, in the 36th week of gestation, with acute abdomen due to hemoperitoneum. Ultrasound revealed free fluid in the abdominal cavity, with no signs of fetal distress, and the patient was mildly hypotensive. Exploratory laparotomy and cesarean section were performed, and extensive blood clots on the upper abdominal quadrants were discovered, as well as a bleeding left uterine artery. We expect that this case raises awareness of the ruptured uterine artery as a possible etiology of hemoperitoneum during pregnancy.

Spontaneous coronary artery rupture after lung cancer surgery: A case report and review of literature.

BACKGROUND: Spontaneous coronary artery rupture (SCAR) is a rare and life-threatening complication after lung cancer surgery. We present a case of SCAR following left upper lobectomy, successfully managed through emergency thoracotomy and coronary artery ligation. CASE SUMMARY: A 61-year-old male patient underwent left upper lobectomy and mediastinal lymph node dissection for lung cancer. The surgery was performed using single-port video-assisted thoracoscopic surgery, and there were no observed complications during the procedure. However, 19 h after surgery, the patient experienced chest discomfort and subsequently developed severe symptoms, including nausea, vomiting, and a drop in blood pressure. Urgent measures were taken, leading to the diagnosis of SCAR. The patient underwent emergency thoracotomy and coronary artery ligation, successfully stopping the bleeding and stabilizing the condition. Despite postoperative complications, the patient made a successful recovery and was discharged from the hospital. CONCLUSION: SCAR is a rare but life-threatening complication following lung cancer surgery. Immediate thoracotomy has been shown to be a life-saving measure, while stenting is not the preferred initial approach.

Idiopathic spontaneous intraperitoneal haemorrhage: A near fatal presentation of acute abdomen requiring prompt diagnosis.

INTRODUCTION AND IMPORTANCE: Idiopathic spontaneous intraperitoneal haemorrhage is a rare and life-threatening condition that results from non-traumatic visceral artery rupture in the latter half of pregnancy and within the postpartum period [1-3]. CASE PRESENTATION: A 32 -year-old woman presented to emergency department, 14 weeks post-partum, with sharp left sided abdominal pain, nausea, and vomiting. Initial computed tomography (CT) was suggestive of non-specific colitis from transverse to descending colon of unclear cause. Six hours into admission she became haemodynamically unstable with abdominal peritonism resulting in emergency laparotomy. Intra-operative findings showed large volume haemoperitoneum with an active bleed from the middle colic artery. CLINICAL DISCUSSION: Symptoms and clinical presentation of Idiopathic spontaneous intraperitoneal haemorrhage is variable and ranges from vague abdominal pain to haemorrhagic shock. A latent period of several hours may be followed by a rapid progression of symptoms owing to rapidity of extravasation[3]. Pathogenesis has been suggested to arise from the increased physiologic demands during the intrapartum period, wherein repeated distension of vessels and increased tortuosity leads to a predisposition for rupture [4]. CONCLUSION: Diagnosis of Idiopathic spontaneous intraperitoneal haemorrhage is difficult but should be a differential in those who are post-partum presenting with abdominal pain. Patients should be assessed with CT angiography and treatment focused around aggressive resuscitation, surgical exploration, and ligation [3].

Transplant Hepatic Artery Rupture.

A case of transplant hepatic artery thrombosis treated with thrombolysis and vascular stenting is presented. Stenting was complicated by hepatic artery rupture necessitating emergent stent graft placement. Hepatic artery occlusion in a liver transplant often leads to biliary complications such as ischemic cholangiopathy, biliary necrosis, cholangitis, biloma formation, intrahepatic abscesses, and liver failure. Prompt recognition and appropriate treatment of hepatic artery thrombosis are necessary to avoid graft failure and possible death.

Life threatening, subclavian artery mycotic aneurysm rupture into a gigantic supraclavicular abscess in an intravenous drug user.

Subclavian artery injuries are sporadic, and the most common aetiology is trauma. Self-injury of the vessel in those misusing intravenous drugs is a rare complication, as most reports describe injury to the femoral artery. Thus, erosion and potential rupture of the arterial wall is possible due infection and phlegmon or abscess formation. We present a case of a young, female, hemodynamically unstable intravenous drug user admitted to the emergency department with a life-threatening, purulent haemorrhagic mass located at her right lateral cervical region. The patient admitted an inadvertent arterial puncture 10 days prior and an effort to self-manage the bleeding with the application of self-pressure and antibiotics. Computed tomography arteriogram of the neck revealed a gigantic, multicompartment, thick-walled collection with hyperdense fluid in her right supraclavicular region while active extravasation derived from the right subclavian artery was evident in late arterial phase. The patient was treated with endovascular graft stenting, despite the given presence of infection, as a salvage operation due to time limitation in open surgical repair.

Delayed rupture of the iliac artery after endovascular therapy.

Iliac artery rupture during endovascular therapy (EVT) is a life-threatening complication requiring prompt diagnosis and treatment. However, delayed rupture of the iliac artery after EVT is rare, and its predictive value remains unknown. Herein, we present the case of a 75-year-old woman who developed delayed iliac artery rupture 12 h after balloon angioplasty and placement of a self-expandable stent in the left iliac artery. Hemostasis was achieved with a covered stent graft. However, the patient died of hemorrhagic shock. From the review of previous case reports and the pathological findings of the current case, increased radial force due to overlapping stent and kinking of the iliac artery may be associated with delayed iliac artery rupture. Learning objective: Delayed iliac artery rupture after endovascular therapy is rare but with a poor prognosis. Hemostasis can be achieved using a covered stent; however, the outcome could be fatal. Based on pathological findings and previous case reports, increased radial force at the stent site and kinking of the iliac artery may be associated with delayed iliac artery rupture. Self-expandable stent probably should not be overlapped at the site where kinking is likely to occur, even if long stenting is needed.

The C-CAT sign may predict coronary artery perforation in severe calcified lesions during coronary intervention: a case series.

Background: Coronary artery rupture is a rare but fatal complication of percutaneous coronary intervention (PCI). The mortality rate reaches 19% in patients with the Ellis type III classification. The predictors of coronary artery rupture were reported in previous studies. However, there are few reports showing the risk factors of this threatening complication in terms of intravascular image such as optical coherence tomography and intravascular ultrasound (IVUS). Case summary: We report the case of three patients with coronary artery rupture, who underwent IVUS-guided PCI for severe calcified lesions. All three patients developed the Ellis grade III rupture, which was successfully managed with the use of a perfusion balloon and covered stents. In these patients, the common characteristics were observed in pre-procedural IVUS images. Specifically, a C-type CAlcified and residual Thin plaque sign (C-CAT sign) was seen in all three patients. Discussion: These patient cases provide an insight into the coronary artery rupture in severe calcified lesions. The C-CAT sign in the pre-IVUS image may predict coronary artery rupture. If we obtain such a unique IVUS image before intervention, we have to consider using a smaller balloon size, for example a half size down, judging from the vessel diameter of the reference site or using ablation devices such as orbital atherectomy and rotational atherectomy to prevent coronary artery rupture. Conclusion: The C-CAT sign may predict coronary artery perforation in severe calcified lesions during PCI, although larger registries of such intracoronary pre-perforation imaging are required in order to correlate different signs with outcomes.

Case report: Right coronary artery rupture-A rare complication of cardiopulmonary resuscitation.

An 8-month-old female experienced a life-threatening right coronary artery rupture resulting from cardiopulmonary resuscitation (CPR) 1 week after corrective surgery for Tetralogy of Fallot (TOF). Emergency exploratory thoracotomy was performed due to uncorrectable hemorrhagic shock. During exploration, active bleeding was detected in the anterior branch of the right ventricular coronary artery. After the repair, the patient's condition improved. Coronary artery rupture is an extremely rare complication of CPR. Here, we present a case that provides new reflections and warnings to clinicians.

Treatment of celiac artery rupture with a hybrid procedure involving aortic stent grafting and open surgery in a patient with neurofibromatosis type 1.

Neurofibromatosis type 1 is associated with vascular fragility, and vascular disease is the second leading cause of death in these patients. A 42-year-old woman with neurofibromatosis type 1 was transferred to our hospital owing to shock. A computed tomography scan revealed a ruptured celiac artery aneurysm, which had expanded from 14 to 26 mm in 1 day. The survival rate of patients with celiac artery rupture is extremely low, and there is no consensus on treatment. Here, we successfully performed a hybrid procedure with emergent implantation of aortic stent grafts for life-saving treatment and subsequent laparotomy for complete hemostasis.

Successful liver and kidneys transplant following aortic dissection and subclavian artery rupture: A case report.

INTRODUCTION AND IMPORTANCE: Despite the increasing number of liver and kidney transplants, the number of patients awaiting for a proper donor is still exceeding. Therefore, the preservation of donor organs is critically advocated. CASE PRESENTATION: Herein, we presented a successful liver and kidney transplant from a brain-dead donor who was found preoperatively to have simultaneous aortic dissection and intramural hematoma and additionally developed left subclavian artery dissection and perforation, which was noticed following sternotomy. CLINICAL DISCUSSION: This case experience highlights the key role of cardiac surgeons in preserving visceral organs by rapid repair of the dissection and perforation sites of the aorta and its branches which culminate in lifesaving organ donation. CONCLUSION: This case report introduces the first case of a successful; liver and kidneys transplant in a patient with concurrent aortic dissection and subclavian artery rupture which served as a lifesaving donor.

An isolated brachiocephalic artery rupture on penetrating trauma in a 9-year-Old child - A case report.

Introduction and Importance: A stab or penetrating wound is one of the etiologies of chest trauma. In the case of penetrating chest trauma, assessment of probable major vascular injuries must be done. Thoracic, vascular injuries, in particular brachiocephalic rupture, require the surgeon to make swift decisions for repair as the wrong approach or incision could quickly lead to mortality. Case presentation: Here, we report a case of a hemodynamically stable 9-year-old boy presenting with a stab wound by a fishing arrow. CT scan showed the fishing arrow projection at the suprasternal notch extended to the right hemithorax where the tip was near the brachiocephalic artery posterior wall. A sternotomy exploration and preservation of the proximal brachiocephalic artery, subclavian artery, and common carotid artery was done. We found a 0.5 cm rupture on the brachiocephalic truncus and performed a direct suture repair. Discussion: Through this case, we present a vascular technique repair after the major thoracic artery rupture caused by a stab or penetrating wound. The principle of artery repair is to save the proximal and distal end of the ruptured artery, followed by a further safe and precise procedure. Conclusion: The overall combination of approaches of chest trauma by a penetrating wound and vascular injury like brachiocephalic rupture without pseudoaneurysm or other asymptomatic high risks of vascular injury resulted in a satisfactory evaluation. In this case, leaving the arrow undisturbed is the key to the success of the first aid management before the patient is sent to the operating room.

Successful Percutaneous Intervention of Contained Coronary Artery Rupture: The Role of Intracoronary Imaging.

A 66-year-old male presented with ST-segment-elevation myocardial infarction. Percutaneous coronary intervention (PCI) of the culprit right coronary artery lesion was performed, during which a small wire-related perforation was noted. The perforation was no longer visible post procedure and we opted for conservative management. One month later, coronary angiography before intervention of the left anterior descending and circumflex lesions revealed a focal dilation at the site of the earlier wire perforation. Further imaging with intravascular ultrasound and optical coherence tomography visualized the defect and guided treatment options.

Infective Artery Rupture of Renal Allografts: A Single-Center Retrospective Study in China.

OBJECTIVE: This study investigated the composition of pathogenic microorganisms, clinical features, and therapeutic strategies of infective artery rupture of renal allografts in recipients receiving deceased donor (DD) kidneys. METHODS: We retrospectively studied the clinical data of the DD kidney transplant recipients with donor-associated infection at Tongji Hospital, Wuhan, China from January 1, 2015 to December 31, 2018, related recipients and corresponding donors. We collected the entire results of pathogenic microorganisms cultured from these related ruptured kidneys and then analyzed their distribution and differences. RESULTS: A total of 1440 kidney transplants from DD were performed in our center. The total incidence of infective artery rupture in kidney transplants was about 0.76% (11/1440), and the annual incidence ranged from 0.25% to 1.03%. The microbial culture results revealed that 11 recipients suffered from infective artery rupture and 3 recipients who accepted the kidney from same donor had the donor-associated pathogens, including 9 fungal strains (28.1%) and 23 bacterial strains (71.9%). There were 4 recipients infected with multi-drug-resistant Staphylococcus and Klebsiella pneumoniae from the above 11 recipients, of which, 10 recipients underwent graft loss, and one died of septic shock. The microbial cultures of the remaining 3 recipients who received appropriate anti-infective regimens turned negative eventually, and the patients were discharged successfully without significant complications. CONCLUSION: Renal recipients with infections derived from DDs were at high risk of artery rupture, graft loss, or even death. Appropriate anti-infective treatment is essential to reduce the incidence of artery rupture and mortality.

Sudden Cardiac Arrest Due to Spontaneous Coronary Artery Rupture - A Case Report with a Diagnostic Challenge.

Spontaneous coronary artery rupture (SCAR) is a rare, life-threatening disease, and the diagnosis is often challenging. We herein report a 70-year-old man who suffered sudden cardiac arrest due to SCAR with pericardial fluid. At first, emergent coronary angiography (CAG) failed to detect abnormalities. The emergent operation revealed that the presence of pericardial fluid was caused by bleeding that had spontaneously occurred at the left circumflex artery (LCx). A careful retrospective CAG review showed slight contrast spillage from the distal LCx. SCAR should be suspected in patients with unknown etiology of pericardial effusion, and careful inspection of CAG is necessary.

Late Open Repair of a Massive Common Iliac Artery Aneurysm after Endovascular Failure.

Giant Common Iliac Artery Aneurysms (CIAA) are an uncommon pathology that may present as a late complication after endovascular aortic repair secondary to aneurysmal degeneration with endoleak. We present an unusual case of a patient presenting 9 years after index endovascular CIAA exclusion with a painless abdominal mass found to be a 20+ cm CIAA secondary to type II endoleak from a recanalized coil embolized hypogastric artery. The patient underwent open aneurysmorrhaphy with ligation of the hypogastric artery.

A very rare complication of subacute pericarditis: a case report of spontaneous coronary artery rupture.

BACKGROUND: Spontaneous coronary artery rupture (SCAR) is an extremely rare and highly lethal disease. CASE SUMMARY: A 74-year-old man who had undergone respiratory surgery (robot-assisted thoracoscopic surgery) presented with exertional dyspnoea since postoperative day (POD) 6. Echocardiography and contrast-enhanced computed tomography showed diffuse pericardial effusion, and a 12-lead electrocardiogram showed widespread concave ST-segment elevation. The diagnosis of acute pericarditis was made based on the absence of significant elevation of cardiac enzymes and the presence of elevated C-reactive peptide levels. The patient was started on anti-inflammatory medication, including steroids; however, on POD 11, the patient developed a sudden cardiopulmonary arrest due to cardiac tamponade. Extracorporeal cardiopulmonary resuscitation was performed, and an emergency coronary angiography showed contrast extravasation from the left anterior descending artery to the epicardium. He was diagnosed with SCAR and underwent transcatheter arterial embolization (TAE) and pericardial drainage. DISCUSSION: In this case, SCAR occurred during the course of acute pericarditis. We speculated that the cause of SCAR was more affected with pericarditis than injury by the respiratory surgery. The clinical course of acute pericarditis generally has a good prognosis, but the rare occurrence of fatal complications should be considered, suggesting the need for careful follow-up. In addition, TAE was a less invasive and feasible treatment for SCAR.
