Endoscopic lavage for an infected pelvic hematoma in a patient with pelvic sepsis after anterior pelvic exenteration.

Anastomotic leakage and subsequent pelvic sepsis are serious complications after surgery for pelvic malignancies, particularly challenging due to the large pelvic cavity dead space post-exenteration. We report a 47-year-old man treated for a severely infected pelvic hematoma and sepsis following anastomotic leakage after anterior pelvic exenteration. Post robot-assisted exenteration for locally advanced sigmoid colon cancer treated with neoadjuvant chemotherapy, a pelvic abscess from anastomotic dehiscence was identified. Initial CT-guided drainage and subsequent laparoscopic drainage were performed. On postoperative day 22, a bleeding left internal iliac pseudoaneurysm required embolization. Despite these efforts, the sepsis worsened due to an enlarged, infected hematoma. Endoscopic lavage, in collaboration with skilled endoscopists, successfully removed the hematoma, leading to an improved inflammatory response, and the patient was discharged. Endoscopic lavage proved to be the safest and most effective treatment for pelvic sepsis with an infected hematoma after various attempted interventions.

A large forearm subcutaneous hematoma after contrast extravasation requires surgical managements: A case report.

RATIONALE: Large extremity hematoma can rarely happen after contrast extravasation during a contrast-enhanced computed tomography scan. Some hematomas need prompt surgical managements. PATIENT CONCERNS: A 77-year-old man had acute ischemic stroke and received the thrombolytic and antiplatelet therapies. He had a contrast extravasation during the computed tomography scan and developed a large hematoma in the right forearm, despite without evidence of compartment syndrome. DIAGNOSIS: Right forearm hematoma, status post contrast extravasation. INTERVENTIONS: The patient responded poorly to the routine care with arm elevation, cold pack, and wet dressing, and was finally treated by the surgical debridement, vacuum sealing drainage, fascioplasty, and skin flap repair. OUTCOMES: Right forearm wound healed with a scar. LESSONS: Large extremity hematoma can happen after contrast extravasation during computed tomography scan, which may require surgical treatments. Careful preparation, close monitor, and prompt managements should be applied in high-risk patients.

Total aortic arch replacement with frozen elephant trunk technique for intramural haematoma of the thoracic aorta.

Presenting this video tutorial, we want to demonstrate a step-by-step surgical approach to acute intramural haematoma of the thoracic aorta without a definite entry tear. Limited by the aortic valve proximally, the intramural haematoma involved the aortic root, ascending aorta, aortic arch, including adjacent parts of supra-aortic branches, and descending aorta extending to the diaphragmatic level. The operative strategy involved urgent total aortic arch replacement with the frozen elephant trunk technique and anatomical reimplantation of the three supra-aortic vessels. The direct open over-the-wire technique was used to cannulate the right axillary artery, and standard venous cannulation was performed while brain protection was achieved with bilateral selective antegrade cerebral perfusion.

Spontaneous spinal hematomas: A case series.

PURPOSE: Spontaneous spinal hematoma (SSH), a rare neurological disorder, demands immediate diagnostic evaluation and intervention to prevent lasting deficits. This case series analyzes instances, particularly highlighting cases where vascular causes were identified despite inconclusive initial imaging. METHODS: In a retrospective study of 20 patients treated for SSH at a Level I spine center from 01/01/2017 to 11/15/2023, we examined demographics, clinical presentation, imaging, and treatment details. Excluding traumatic cases, we present 4 instances of SSH associated with diverse vascular pathologies. RESULTS: Patient ages ranged from 39 to 85 years, with a median age of 66 years. 45% were male, and 55% were female. Among 20 cases, 14 were epidural hematomas, 4 subdural, 1 combined epidural and subdural, and 1 subarachnoid hemorrhage. 85% presented with neurological deficits, while 3 solely had pain-related symptoms. 55% were under anticoagulant medication, and vascular anomalies were found in 25% of cases. The cause of SSH remained unclear in 20% of cases. MRI was performed for all patients, and DSA was conducted in 25% of cases. The 4 highlighted cases involved individuals with distinct vascular pathologies managed surgically. CONCLUSION: Urgent attention is crucial for SSH due to possible lasting neurological consequences. The study emphasizes comprehensive diagnostics and surgical exploration, especially in cases with unclear etiology, to identify and address vascular causes, preventing hematoma progression or recurrence. Despite their rarity, vascular malformations contributing to spinal hematomas warrant particular attention.

A patient with cervical ligamentum flavum haematoma: case report.

INTRODUCTION: Ligamentum flavum haematoma (LFH) is an extremely rare entity, found mostly in the lumbar and thoracic ligamentum flavum and seldom in the cervical ligamentum flavum. Cervical LFH can cause paralysis in patients. We describe a case of LFH in the cervical spine that accepted surgical treatment. CASE PRESENTATION: A 70-year-old man with incomplete spinal cord injury presented with sudden paralysis of his left limbs for 10 days and hemi-hypaesthesia below the level of the right clavicle. Magnetic resonance imaging (MRI) showed a space-occupying lesion in the left ligamentum flavum between the C4 and C5 laminae. The preliminary diagnoses were concluded to be incomplete spinal cord injury, spinal epidural lesions, and cervical spinal stenosis. After a posterior C3-C6 laminectomy with lateral mass screw instrumentation, the muscle strength and sensation recovered partially. The lesion was greyish black and located in the ligamentum flavum. A pathological examination identified it as a haematoma of the ligamentum flavum. The patient was discharged 15 days after the operation and commenced rehabilitation. DISCUSSION: The LFH was mainly caused by slight trauma during gentle activities and contributed by many factors. MRI is an essential tool but pathological diagnosis is the gold standard. Most LFH patients can be treated surgically.

Primary decompressive craniectomy in patients with large intracerebral hematomas due to aneurysmal subarachnoid hemorrhage.

BACKGROUND: Decompressive craniectomy (DC) can alleviate increased intracranial pressure in aneurysmal subarachnoid hemorrhage patients with concomitant space-occupying intracerebral hemorrhage, but also carries a high risk for complications. We studied outcomes and complications of DC at time of ruptured aneurysm repair. METHODS: Of 47 patients treated between 2010 and 2020, 30 underwent DC during aneurysm repair and hematoma evacuation and 17 did not. We calculated odds ratios (OR) for delayed cerebral ischemia (DCI), angiographic vasospasm, DCI-related infarction, and unfavorable functional outcome (extended Glasgow Outcome Scale 1-5) at three months. Complication rates after DC and cranioplasty in the aneurysmal subarachnoid hemorrhage patients were compared to those of all 107 patients undergoing DC for malignant cerebral infarction during the same period. RESULTS: In DC versus no DC patients, proportions were for clinical DCI 37% versus 53% (OR = 0.5;95%CI:0.2-1.8), angiographic vasospasm 37% versus 47% (OR = 0.7;95%CI:0.2-2.2), DCI-related infarctions 17% versus 47% (OR = 0.2;95%CI:0.1-0.7) and unfavorable outcome 80% versus 88% (OR = 0.5;95%CI:0.1-3.0). ORs were similar after adjustment for baseline predictors for outcome. Complications related to DC and cranioplasty occurred in 18 (51%) of subarachnoid hemorrhage patients and 41 (38%) of cerebral infarction patients (OR = 1.7;95%CI:0.8-3.7). CONCLUSIONS: In patients with aneurysmal subarachnoid hemorrhage and concomitant space-occupying intracerebral hemorrhage, early DC was not associated with improved functional outcomes, but with a reduced rate of DCI-related infarctions. This potential benefit has to be weighed against high complication rates of DC in subarachnoid hemorrhage patients.

Severe capsular contracture in a patient with a history of multiple malignancies - Hematoma or neoplasm recurrence?: A case report.

RATIONALE: Complications associated with breast implants pose a significant obstacle to improving the quality of life for patients undergoing implant-based breast reconstruction. Due to the intricate nature of their presentation, diagnosis often becomes challenging and perplexing. Herein, we present a case report detailing the diagnostic and therapeutic processes employed in managing implant-related complications in a patient with multiple malignancies who underwent immediate breast reconstruction following mastectomy. PATENT CONCERNS: The patient, a 48-year-old woman, presented with severe pain and hardening in her left breast. She had previously undergone nipple-sparing mastectomy followed by immediate implant-based breast reconstruction 3 years ago. DIAGNOSES: Upon admission, we suspected a simple diagnosis of capsular contracture. However, upon investigation, she had a medical history of colon cancer, breast cancer, and acute B-lymphoblastic leukemia. Furthermore, she recently experienced nipple hemorrhage. INTERVENTIONS: Considering her clinical manifestations, we postulated the possibility of tumor recurrence along with potential presence of breast implant-associated anaplastic large cell lymphoma. The situation took a new turn, as diagnostic imaging techniques including breast MRI, and ultrasound revealed indications of potential prosthesis rupture and periprosthetic infection. OUTCOMES: Ultimately, en bloc capsulectomy with implant removal was performed, revealing no evidence of implant rupture or infection but rather indicating delayed hematoma formation. LESSONS: An accurate diagnosis of complications associated with breast prosthesis reconstruction is crucial for effective treatment. The examination and treatment processes employed in this case offer valuable insights toward achieving a more precise diagnosis of prosthesis-related complications, particularly in patients with complex medical histories.

A comparison of the efficacy of computed tomography-guided minimally invasive puncture and drainage and craniotomy for hematoma evacuation in the treatment of cerebellar hemorrhage.

OBJECTIVE: This study aimed to compare the efficacy of computed tomography (CT)-guided minimally invasive puncture and drainage (MIPD) and craniotomy for hematoma evacuation in the treatment of cerebellar hemorrhage. METHODS: This single-center prospective cohort study was conducted from January 2020 to February 2023. During the study period, 40 patients with cerebellar hemorrhage who underwent CT-guided MIPD treatment were enrolled in the CT-guided MIPD (CTGMIPD) group, and 40 patients with the cerebellar hemorrhage who had a propensity score matching that of the CTGMIPD group and who underwent craniotomy for hematoma evacuation were enrolled in the standard craniotomy (SC) group. The primary outcome indicators were the 6-month mortality of the patients and the proportion of survivors with a modified Rankin Scale (mRS) scores of 1 or 2. The secondary outcome indicators were the cerebellar hematoma volume, National Institutes of Health Stroke Scale (NIHSS) score, Glasgow Coma Scale (GCS) score, incidence of postoperative complications, length of hospital stay, and medical costs. In addition, data concerning the patients who died during the study period were further analyzed. RESULTS: At the 6-month follow-up, there was no significant difference in mortality between the two groups, although the proportion of patients with an mRS scores of 1 or 2 was significantly higher in the CTGMIPD group when compared with the SC group (P = 0.015). No significant differences were observed in the hematoma volume, NIHSS score, and GCS score between the two groups. By contrast, the incidence of postoperative complications, length of hospital stay, and medical costs were significantly lower in the CTGMIPD group than in the SC group (all P < 0.05). When compared with the SC group, the proportion of dead patients with a hematoma volume greater than 30 ml was higher in the CTGMIPD group (P = 0.03). Moreover, after stratification of the patients with a preoperative GCS score ≤8, the CTGMIPD group had a significantly higher mortality rate than the SC group (P = 0.04). CONCLUSION: The efficacy of CT-guided MIPD in the treatment of cerebellar hemorrhage is close to that of craniotomy for hematoma excavation, although the complication and disability rates of the former are significantly lower than those of the latter. When the preoperative hematoma volume is less than 30 mL or the preoperative GCS score is greater than 8, CT-guided MIPD represents a better choice for the treatment of cerebellar hemorrhage than craniotomy for hematoma evacuation.

Purely Endoscopic Evacuation of Intracranial Hematomas.

Cerebral hemorrhage is a frequent disease and one of the main causes of disabilities. Even in the case of cerebral hemorrhage, if there were a treatment that would improve the functional prognosis, the benefits would be immeasurable. Although there are limited reports with a high level of evidence in past studies, it has been found that surgery can be effective if a large amount of hematoma can be removed in a minimally invasive manner. Also, it has become clear that the control of bleeding becomes a problem when surgery is performed within 2 days after the onset of stroke and that the therapeutic time window might be longer. In Japan, since the introduction of the transparent sheath by Nishihara et al., endoscopic hematoma removal has been widely performed and has become the standard surgical procedure. The three basic equipment needed for this surgery are a rigid scope, a suction coagulator, and a transparent sheath. The key point of the surgery is to search for hematomas and bleeding points through a transparent sheath and coagulate the bleeding vessels. In this chapter, we will introduce surgical techniques using these devices, but it is important to carefully decide on surgical options by considering your own technique, the condition of each patient, and the devices available in the area.

Unusual case of Reinke's oedema.

This case report describes a man in his mid 40s, with a history of chronic smoking, who presented with dysphonia. He underwent microlaryngoscopy and biopsy for a suspicious lesion on the anterior right vocal cord. Mask ventilation proved difficult on induction of general anaesthesia due to a solid lesion acting as a ball valve into the glottis. This mass was LASER debulked and sent for histopathology. This demonstrated a haematoma, likely traumatic in origin, with some polypoidal features, consistent with advanced Reinke's oedema. Reinke's oedema is a benign condition where chronic inflammation causes fluid accumulation within the vocal cords. Long-standing inflammation leads to disarrangement of the vocal cord lamina propria, causing fluid accumulation and thereby resulting oedema of the vocal cords. This process can subsequently lead to polyp formation and can cause gravelly voice. This case report describes the potential airway sequelae of this benign condition.

Aortic arch de-branching for suspected expanding perigraft haematoma after previous acute type-A dissection repair with AMDS stent: a technique for a potential future problem.

BACKGROUND: Acute Stanford type- A aortic dissections make up a large part of emergency cardiac surgery. They also carry a significant burden of morbidity. New techniques to aid aortic remodelling include the Ascyrus Medical Dissection Stent (AMDS): Its increasing use, looks to present a potential problem in cases where surgery involving the aortic arch may be required. CASE REPORT: We present the case of a 49-year-old male who underwent urgent redo-surgery for total arch replacement and de-branching following recent replacement of the ascending aorta for acute type-A dissection, where an AMDS stent was deployed. The patient underwent total arch replacement with a stented tri-furcate prosthesis and de-branching of arch vessels with the stent landed inside the previous AMDS, to good effect. CONCLUSION: This case highlights a possible approach to aortic arch surgery in patients who have previous had AMDS insertion.

Safety of Endoscopic Surgery for Spontaneous Intracerebral Hemorrhage in the Registry of Intracerebral Hemorrhage Treated by Endoscopic Hematoma Evacuation in Japan.

OBJECTIVE: The long history of treatment for intracerebral hemorrhage (ICH) includes the development of surgical procedures. However, few studies have demonstrated that surgery improved the functional outcome. The present study used the prospective Registry of Intracerebral hemorrhage treated by endoscopic hematoma evacuation of the outcomes in endoscopic surgery, which is widely followed in Japan, to try to establish clinical evidence. METHODS: The Registry of Intracerebral hemorrhage treated by endoscopic hematoma evacuation is a multicenter, prospective registry in Japan, and included 143 surgical cases treated by certified neurosurgeons. The etiology and the location of ICH was evaluated by univariate and multivariate analyses as follows: deep, surface, intraventricular hemorrhage, cerebellum, and surgical outcome. RESULTS: Hematoma location was deep in 44.8% of cases, intraventricular hemorrhage in 19.6%, surface in 21.7%, and cerebellum in 14.0%. Most cases were treated in the ultraearly stage within 8 hours. Mean hematoma evacuation rate was 83.6% and median residual hematoma volume was 3.0 ml. Duration of surgery was median 78 minutes. Rebleeding as a complication was observed in 6.7%, but only 2.9% were symptomatic. 2 cases required reoperation. Favorable outcome at 6 months was achieved in 35.8% of cases, with a mortality rate of 5.6%. CONCLUSIONS: Endoscopic surgery for spontaneous ICH is safe and comparable to conventional surgery. The time required for the procedure was significantly reduced, demonstrating the minimally invasive character of the surgical burden. However, this study did not establish whether minimally invasive surgery is superior to conservative treatment. Future randomized controlled trials should clarify the effectiveness of the treatment.

A Keyhole Approach for Intracranial Hematoma Removal Using ORBEYE.

OBJECTIVE: By maximizing the advantages of exoscopy, we developed a keyhole approach for intracranial hematoma removal. Herein, we validated the utility of this procedure, and compared it with conventional microscopic hematoma removal and endoscopic hematoma removal in our institution. METHODS: We included 12 consecutive patients who underwent this procedure from June 2022 to March 2024. A 4-cm-long skin incision was made, and a keyhole craniotomy (diameter, 2.5 cm) was performed. An assistant manipulated a spatula, and an operator performed hematoma removal and hemostasis using typical microsurgical techniques under an exoscope. The dura mater was reconstructed without sutures using collagen matrix and fibrin glue. The outcomes of this series were compared with those of 12 consecutive endoscopic hematoma removals and 19 consecutive conventional microscopic hematoma removals from October 2018 to March 2024. RESULTS: The mean age was 72±10 years, and 7 (58%) patients were men. Hematoma location was the putamen in 5 patients and subcortical in 7 patients. The mean operative time was 122±34 min, the mean hematoma removal rate was 95%±8%, and the mortality rate was 0%. Although the preoperative hematoma volume was similar between the 3 groups, the operative time and total time in the operating room was significantly shorter in the exoscope group than in the microscope group (P<0.0001). CONCLUSIONS: This procedure may be simpler and faster than conventional microscopic hematoma removal, and comparable to endoscopic hematoma removal.

CT scan the key to unmasking a solid pseudopapillary pancreatic neoplasm in blunt abdominal trauma.

SUMMARY: We present a previously healthy 13-year-old male, who sustained a handlebar injury after falling from his bicycle. The computerised tomography (CT) scan indicated a probable pancreatic neoplasm associated with a retroperitoneal haematoma which was, following resection, confirmed histologically to be a solid pseudopapillary neoplasm of the pancreas. These are rare tumours of the pancreas, especially in young males. The rarity of this neoplasm and the mechanism that led to its presentation make this an interesting and unique case.

Delayed femoral artery injury caused by heterotopic ossification: a rare case report and review of the literature.

BACKGROUND: Arterial injury caused by heterotopic ossification (HO) following fractures is rarely reported, yet it can have catastrophic consequences. This case report presents a unique instance of femoral artery injury and hematoma organization, occurring a decade after intramedullary nail fixation for a femoral shaft fracture complicated by HO. CASE PRESENTATION: A 56-year-old male presented with right femoral artery injury and organized hematoma, a decade after suffering bilateral femoral shaft fractures with mild head injury in a traffic accident. He had received intramedullary nailing for the right femoral shaft fracture and plate fixation for the left side in a local hospital. Physical examination revealed two firm, palpable masses with clear boundaries, limited mobility, and no tenderness. Peripheral arterial pulses were intact. Radiography demonstrated satisfactory fracture healing, while a continuous high-density shadow was evident along the inner and posterior aspect of the right thigh. Computed tomography angiography identified a large mixed-density mass (16.8 × 14.8 × 20.7 cm) on the right thigh's medial side, featuring central calcification and multiple internal calcifications. The right deep femoral artery coursed within this mass, with a smaller lesion noted on the posterior thigh. Surgical consultation with a vascular surgeon led to planned intervention. The smaller mass was completely excised, but the larger one partially, as it encased the femoral artery. The inability to remove all HO was due to excessive bleeding. Postoperatively, the patient experienced no complications, and one-year follow-up revealed a favorable recovery with restoration of full right lower limb mobility. CONCLUSION: This case underscores the potential gravity of vascular injury associated with heterotopic ossification. Surgeons should remain vigilant regarding the risk of vascular injury during HO excision.

The Usefulness of the 3.1-mm-diameter 4K Rigid Endoscope for Intracerebral Hematoma Evacuation.

The indication for surgical intervention in spontaneous intracerebral hemorrhage remains controversial. Although many clinical trials have failed to demonstrate its efficacy over medical treatment, less invasive endoscopic treatment is expected to demonstrate its superiority. A novel endoscopic system for hematoma removal consisting of a 3.1-mm-diameter 4K high-resolution rigid endoscope was used.The system was used in eight cases of spontaneous intracerebral hemorrhage. It provided improved maneuverability of the surgical instrument while maintaining satisfactory image quality. The surgical goal was achieved in all cases without any complications, including perioperative rebleeding.Endoscopic hematoma removal using the 3.1 mm high-resolution endoscope is an alternative minimally invasive approach to spontaneous intracerebral hemorrhage with improved reliability.

Management of Intramyocardial Dissecting Hematoma Following Myocardial Infarction.

Intramyocardial dissecting hematoma (IDH) is a rare condition mostly seen following acute myocardial infarction, chest trauma, and cardiac surgery. It is described as an incomplete rupture caused by hemorrhagic dissection within the myocardium, rather than extending to the epicardial layer. Management strategies for IDH are controversial due to limited reports. We present a case of a 61-year-old man diagnosed with IDH, left main, and three-vessel disease, subsequently treated surgically.

Spontaneous retroperitoneal haemorrhage after pulmonary endarterectomy surgery.

Spontaneous retroperitoneal hematoma (SRH) is a rare complication of anticoagulation therapy. Presentation may vary from limb paresis to hypovolemic shock due to blood loss. The optimal treatment is controversial. It can be managed conservatively or surgically. We report a case of a 73-year-old man presenting with progressively worsening abdominal pain and severe pain radiating to his left lower limb twenty-five days after his pulmonary endarterectomy (PEA) surgery. He was on anticoagulation per our institutional protocol for PEA patients. Investigations revealed a large, spontaneously occurring iliopsoas hematoma. Our patient was treated conservatively, and the SRH stabilised.

The Effect of Tranexamic Acid on Neurosurgical Intervention in Spontaneous Intracerebral Hematoma: Data From 121 Surgically Treated Participants From the Tranexamic Acid in IntraCerebral Hemorrhage-2 Randomized Controlled Trial.

BACKGROUND AND OBJECTIVES: An important proportion of patients with spontaneous intracerebral hemorrhage (ICH) undergo neurosurgical intervention to reduce mass effect from large hematomas and control the complications of bleeding, including hematoma expansion and hydrocephalus. The Tranexamic acid (TXA) for hyperacute primary IntraCerebral Hemorrhage (TICH-2) trial demonstrated that tranexamic acid (TXA) reduces the risk of hematoma expansion. We hypothesized that TXA would reduce the frequency of surgery (primary outcome) and improve functional outcome at 90 days in surgically treated patients in the TICH-2 data set. METHODS: Participants enrolled in TICH-2 were randomized to placebo or TXA. Participants randomized to either TXA or placebo were analyzed for whether they received neurosurgery within 7 days and their characteristics, outcomes, hematoma volumes (HVs) were compared. Characteristics and outcomes of participants who received surgery were also compared with those who did not. RESULTS: Neurosurgery was performed in 5.2% of participants (121/2325), including craniotomy (57%), hematoma drainage (33%), and external ventricular drainage (21%). The number of patients receiving surgery who received TXA vs placebo were similar at 4.9% (57/1153) and 5.5% (64/1163), respectively (odds ratio [OR] 0.893; 95% CI 0.619-1.289; P -value = .545). TXA did not improve outcome compared with placebo in either surgically treated participants (OR 0.79; 95% CI 0.30-2.09; P = .64) or those undergoing hematoma evacuation by drainage or craniotomy (OR 1.19 95% 0.51-2.78; P -value = .69). Postoperative HV was not reduced by TXA (mean difference -8.97 95% CI -23.77, 5.82; P -value = .45). CONCLUSION: TXA was not associated with less neurosurgical intervention, reduced HV, or improved outcomes after surgery.
