RESUMO

Objective: To investigate the digital subtraction angiography (DSA) manifestations of hemorrhage after partial nephrectomy (PN) for renal tumors, and the safety and efficacy of interventional therapy. Methods: The clinical data, DSA images and interventional treatment of 15 patients undergoing emergency interventional therapy due to hemorrhage after PN in the Department of Interventional Therapy of Beijing University Cancer Hospital from January 2015 to January 2019 were retrospectively analyzed. The DSA manifestations, safety and prognosis of interventional therapy were summarized. Results: Among the 15 patients, 10 had abdominal hemorrhage, 2 had abdominal hemorrhage with hematuria, and 3 had hematuria, all of which occurred 6 hours to 7 days after the operation. The DSA manifestations included contrast medium overflow, local artery wall unevenness, local artery branch expansion, pseudoaneurysm formation and renal arteriovenous fistula. There were 14 survivors, followed up for 6-12 months, and further no bleeding occurred. The success rate of interventional therapy was 100% (14/14), and the success rate of hemostasis was 100% (14/14). One patient died of asphyxia due to intraoperative nausea and vomiting. The creatinine levels were (76.0±11.0), (80.0±9.0), (76.0±9.0) µmol/L before operation, 1 week after operation and 1 month after operation respectively. There was no significant difference in creatinine levels among the three groups (F=3.171, P=0.058). The levels of urea nitrogen before operation, 1 week after operation and 1 month after operation were (6.80±1.04), (7.13±0.89), (6.81±0.79) µmol/L respectively. There was significant difference among the three groups (F=4.322, P=0.024). The level of urea nitrogen at 1 month after operation was significantly lower than that at 1 week after operation (P=0.016), but there was no difference compared with that before operation (P=1.000). Conclusion: Contrast medium overflow, pseudoaneurysm formation and renal arteriovenous fistula were the main manifestations of DSA hemorrhage after PN. Interventional therapy was safe and effective and might be a priority in cases of hemorrhage after PN.

RESUMO

RATIONALE: Stent retriever mechanical thrombectomy is a recommended treatment for acute ischemic stroke. However, refractory thrombus in artery bifurcation can reduce the rate of successful revascularization. PATIENT CONCERNS: A 72-year-old male, owing to the acute onset of almost complete right-sided hemiplegia and global aphasia, received bridging therapy. National Institutes of Health Stroke Scale score was 16 at the time of admission. DIAGNOSES: Cerebral digital subtraction angiography revealed occlusion of the M1 segment of the left MCA. INTERVENTIONS: Thrombectomy with 3 passes of the Solitaire FR device (Medtronic, Minneapolis, MN) was unsuccessful. Two stent retrievers were inserted in parallel by one microcatheter access point to each M2 branch, and then both stents were gradually retrieved out of the catheter while continuous suction was maintained. OUTCOMES: After thrombectomy, subsequent follow-up angiograms showed mTICI 3 reperfusion of MCA. The patient has mRS 2 at discharge and the 3-month mRS score after stroke is 1 score. LESSONS: The presented Y-configuration double-stent-retriever thrombectomy technique constitutes a safe and effective rescue treatment method for refractory thrombus in MCA bifurcation.

RESUMO

In recent years, in the absence of venous component, dilated, overlapping, and tortuous arteries forming a mass of arterial loops with a coil-like appearance have been defined as pure arterial malformation (PAM). It is extremely rare, and its etiology and treatment have not yet been fully elucidated. Here, we reported 2 cases of PAM with associated aneurysmal subarachnoid hemorrhage in this paper. Both patients had severe headache as the first symptom. Subarachnoid hemorrhage was found by CT and computed tomography angiography (CTA) and PAM with associated aneurysm was found by digital subtraction angiography (DSA). In view of the distribution of blood and the location of aneurysms, the aneurysm rupture was the most likely to be considered. Based on the involvement of the lesion in the distal blood supply, only the aneurysm was clamped during the operation. It used to be consider that PAM is safety, because of the presentation and natural history of previously reported cases. Through the cases we reported, we have doubted about "the benign natural history" and discussed its treatment. PAM can promote the formation of aneurysms and should be reviewed regularly. The surgical indications for PAM patients with aneurysm formation need to be further clarified. Management of PAM patients with ruptured aneurysm is the same as that of ruptured aneurysm. Whether there are indications needed to treat simple arterial malformations remains to be further elucidated with the multicenter, randomized controlled studies on this disease.

RESUMO

Haemodynamic flow-related stress at the vessel curvatures is an important risk factor for intracranial aneurysmal growth and rupture. The rete middle cerebral artery (MCA) is a rare entity causing hyperdynamic blood flow into the ipsilateral anterior cerebral artery (ACA), especially when the contralateral A1-segment is non-dominant. Ruling out the clinicoradiological mimics like vasculitis, moyamoya and chronic occlusive disease with vessel wall imaging and detailed investigations helps manage the clinical entity effectively. We present a successfully managed case of ruptured ACA aneurysm at the acute curvature of the A1-A2 junction associated with ipsilateral rete MCA. Pre-emptive diagnosis of the rete MCA can aid preventive strategies to manage rupture and regrowth of the aneurysm at the points of flow-related stress.

RESUMO

ABSTRACT: To evaluate the feasibility and potential value of 2D Parametric Parenchymal Blood Flow (2D-PPBF) for the assessment of perfusion changes following partial spleen embolization (PSE) in a retrospective observational study design.Overall, 12 PSE procedures in 12 patients were included in this study. The outcome of the study was the platelet response (PR), calculated as the percentage increase of platelet count (PLT), following PSE. To quantify perfusion changes using 2D-PPBF, the acquired digital subtraction angiography series were post-processed. A reference region-of-interest (ROI) was placed in the afferent splenic artery and a target ROI was positioned on the embolization territory of the spleen on digital subtraction angiography series pre- and post-embolization. The ratios of the target ROIs to the reference ROIs were calculated for the Wash-In-Rate (WIR), the Time-To-Peak (TTP) and the Area-Under-the-Curve (AUC). Comparisons between pre- and post-embolization data were made using Wilcoxon signed-rank test and Spearman's rank correlation coefficient (r). Afterwards, the study population was divided by the median of the TTP before PSE to analyze its value for the prediction of PR following PSE.Following PSE, PLT increased significantly from 43,000 ±â€Š21,405 platelets/µL to 128,500 ±â€Š66,083 platelets/µL with a PR of 255 ±â€Š243% (P = .003). In the embolized splenic territory, the pre-/post-embolization 2D-PPBF parameter changed significantly: WIRpre-PSE 1.23 ±â€Š2.42/WIRpost-PSE 0.09 ±â€Š0.07; -64 ±â€Š46% (p = 0.04), TTPpre-PSE 4.41 ±â€Š0.99/TTPpost-PSE 5.67 ±â€Š1.52 (P = .041); +34 ±â€Š47% and AUCpost-PSE 0.81 ±â€Š0.85/AUCpost-PSE 0.14 ±â€Š0.08; -71 ±â€Š18% (P = .002). A significant correlation of a 2D-PPBF parameter with the PLT was found for TTPpre-PSE/PLTpre-PSE r = -0.66 (P = .01). Subgroup analysis showed a significantly increased PR for the group with TTPpre-PSE >4.44 compared to the group with TTPpre-PSE ≤4.44 (404 ±â€Š267% versus 107 ±â€Š76%; P = .04).2D-PPBF is an objective approach to analyze the perfusion reduction of embolized splenic tissue. TTP derived from 2D-PPBF has the potential to predict the extent of PR during PSE.

RESUMO

RATIONALE: Despite significant advances in surgical techniques and implants, the clinical outcome of high-energy pilon fractures remains unsatisfactory, which continues to represent numerous challenges for orthopedic trauma surgeons. PATIENT CONCERNS: A 62-year-old man injured his right ankle after falling from a 3 m high place. There were no open wounds or other complications. DIAGNOSES: According to the X-ray and CT scans, the patient was diagnosed with pilon fracture (type AO-43-C2) and lateral malleolus fracture of the right limb. INTERVENTIONS: The patient was initially treated with calcaneal traction upon admission to a primary hospital. Five days after the injury, the patient underwent open reduction and internal fixation (ORIF) of the fracture and vacuum sealing drainage (VSD) for wound closure. OUTCOMES: The patient presented to our hospital on the 9th day after the first ORIF operation because of critical ischemia of the affected foot and distal lower leg. Blood circulation did not improve after a series of salvage treatments, and below-knee amputation was ultimately performed. LESSONS: This is a rare case of complete ischemic necrosis following ORIF surgery of a closed pilon fracture due to iatrogenic damage. Standardized treatment that strictly follows the guidelines, instructions, or expert consensus should be promoted in this kind of complicated pilon fracture.

RESUMO

OBJECTIVE: To assess the diagnostic yield of lateral decubitus digital subtraction myelography (LDDSM) and stratify LDDSM diagnostic yield by the Bern spontaneous intracranial hypotension (SIH) score of preprocedure brain MRI. METHODS: This retrospective diagnostic study included consecutive adult patients investigated for SIH who underwent LDDSM. Patients without preprocedure brain and spine MRI and patients with extradural fluid collection on spine MRI (type 1 leak) were excluded. LDDSM images and brain MRIs were assessed by 2 independent blinded readers; a third reader adjudicated any discrepancies. Diagnostic yield of LDDSM was assessed, both overall and stratified by Bern SIH scoring. RESULTS: Of the 62 patients included in this study, 33 (53.2%) had a CSF leak identified on LDDSM. Right-sided leaks were more common (70.6%), and the most commonly identified levels of leaks were at T6, T7, and T10. No leak was found in any of the 9 patients with Bern SIH score of 2 or less. Of the 11 patients with Bern SIH score of 3-4, 5 (45.5%) had a CSF leak identified; of the 42 patients with Bern SIH score of 5 or higher, 28 (66.7%) had a CSF leak identified. CONCLUSIONS: LDDSM has a high diagnostic yield for finding the exact location of spinal CSF leak, and the diagnostic yield increases with higher Bern SIH score. No leaks were found in patients with Bern SIH score of 2 or less, suggesting that foregoing invasive testing such as LDDSM in these patients may be appropriate unless accompanied by high clinical suspicion. CLASSIFICATION OF EVIDENCE: This study provides Class II evidence that for patients with suspected SIH, higher Bern SIH scores are associated with a greater likelihood of LDDSM-identified CSF leaks.

RESUMO

Objective: To evaluate the diagnostic value of 3.0T time-of-flight MR angiography with sparse undersampling and iterative reconstruction (TOFu-MRA) for unruptured intracranial aneurysms (UIAs) on the basis of using digital subtraction angiography (DSA) as the reference standard. Methods: A total of 65 patients with suspected UIAs were prospectively enrolled and all patients underwent TOFu-MRA and DSA. Relying on DSA as the reference standard, the sensitivity (SEN), specificity (SPE), positive predictive value (PPV) and negative predictive value (NPV) of using TOFu-MRA in UIA diagnosis were calculated, and the inter-observer agreement between two doctors was determined. Comparison of maximum intensity projection (MIP) and volume rendering (VR) image datasets was made to evaluate the agreement between DSA results and TOFu-MRA in the measurement of UIA morphological parameters, including the neck width (D neck), height (H) , and width (D width) of UIAs. Results: The study covered 55 UIAs from 46 patients. The SEN, SPE, PPV and NPV of the two doctors using TOFu-MRA in UIA diagnosis were as follows: (95.7%, 95.7%), (94.7%, 94.7%), (97.8%, 97.8%) and (90.0%, 90.0%), respectively for patient-based assessment; (96.4%, 94.5%), (94.7%, 94.7%), (98.1%, 98.1%) and (90.0%, 85.7%), respectively, for aneurysm-based assessment. There is a strong inter-observer agreement (Kappa=0.93 for patient-based assessment and 0.96 for aneurysm-based assessment) between the two doctors. Moreover, Bland-Altman analysis showed that more than 95% points fell within the limits of agreement (LoA), suggesting strong agreement between the two examination methods for the measurement of UIAs morphological parameters. Conclusion: TOFu-MRA showed good diagnostic efficacy for UIAs and the results were in good agreement with those of DSA, the reference standard, for assessing UIA morphological parameter. TOFu-MRA can be used as a first choice for noninvasive diagnostic evaluation of UIAs.

RESUMO

INTRODUCTION: Although arteriovenous fistulas(AVFs)are typically located within the cranium, there are several published reports documenting rare cases of extracranial AVFs between the ascending pharyngeal artery(APA)and the internal jugular vein(IJV). Herein, we report the case of a patient with APA-IJV AVFs who presented with symptoms of lower cranial nerve palsy that was treated with transvenous embolization(TVE). CASE: A 53-year-old man presented with chief complaints of numbness in the left oral cavity and a temple headache. Magnetic resonance angiography showed an abnormal signal in the left jugular bulb. An AVF was suspected; digital subtraction angiography revealed the presence of a shunt from the jugular branch of the APA to the jugular bulb which was accompanied by regurgitation into the inferior petrosal sinus(IPS)and sigmoid sinus(SS). Numbness in the oral cavity was diagnosed as lower cranial nerve palsy associated with increased pressure within the jugular foramen. As the nature of the AVF(single or multi-hole)was uncertain, a therapeutic TVE was planned. Microcatheters were guided into the IPS and SS, and TVE was performed using a double-catheter technique. Regurgitation into the IPS resolved; embolization via the APA was not performed, and symptoms improved postoperatively. CONCLUSIONS: AVFs involving the APA and IJV are identified infrequently and there are only a few published case reports describing this vascular anomaly. Most reported cases were single-hole AVF and were treated with trans-arterial embolization via the APA. As noted in the present case, APA-IJV AVF can also be treated by TVE.

RESUMO

Acute upper gastrointestinal (UGI) bleeding is one of the most frequent presentations to a surgical emergency. Most of them respond to initial resuscitation, and a definite diagnosis is established as soon as possible, thereby helping the clinician in management. We present the diagnostic challenges that we faced with a 70-year-old man who presented with UGI bleed. He initially responded to resuscitation, but later deteriorated and became haemodynamically unstable. The source of the UGI bleed on evaluation was found to be pseudoaneurysm of the gastroduodenal artery (PsGDA) and treated successfully by coil embolisation. The cause of the PsGDA was diverticulum arising from the first part of duodenum with changes of diverticulitis. Diverticulum originating from the first part of the duodenum is seldom reported. Moreover, diverticulitis involving this part and causing PsGDA has not been reported so far.

RESUMO

A 47-year-old woman with history of seizure disorder (semiology of seizure unknown), not well controlled with antiepileptic drugs since last 30 years presented with 1-year history of intermittent throbbing headache. On the day prior to admission, she experienced worst headache, followed by loss of consciousness. On regaining consciousness, she had neck pain without any focal neurological deficit, but examination was marked by positive meningeal signs. She had history of oral ulceration, photosensitivity and small joints pain for which no medical consultancy was sought until. Following relevant investigations, this case came out to be moyamoya angiopathy secondary to underlying systemic lupus erythematosus. She was put on immunosuppressive and immunomodulator as per recommendations. Among neurological symptoms, headache improved dramatically without any further seizure recurrence till the 6 months of follow-up.

RESUMO

OBJECTIVE: While it is generally considered that patients with diabetes mellitus (DM) have more distal peripheral arterial disease (PAD), there is little information on how individual vessels are affected. The aim of this study was to adapt Bollinger's scoring system for lower limb angiograms (DSAs) to include the distal and planter vessels. The reliability of this extension was tested and was used to compare the distribution of disease in two cohorts of patients with and without DM. METHODS: Patients who had undergone DSA ± angioplasty for PAD at a single centre between September 2010 and April 2014 were identified. Twenty-five patients' images were reviewed by four clinicians and scored using an extended version of the Bollinger score. A total of 153 patients with DM were matched, for age, sex, ethnicity, smoking, and hypertension, with 153 patients without DM. The infrainguinal vessels were divided into 16 arterial segments, including plantar vessels, and scored using the Bollinger score. The score ranges from 0 to 15. Fifteen represents an arterial segment with more than 50% of its length occluded. Interobserver reliability was tested using interclass correlation (ICC) and Cohen's kappa coefficient. RESULTS: The ICC demonstrated good agreement between observers (0.76 [0.72-0.79]) with good internal consistency (Cronbach's alpha 0.93). When the Bollinger scores were categorised, the results were weaker, Cohen's kappa ranged from 0.39 (standard error 0.033) to 0.54 (0.030). Patients with DM had a higher burden of disease in the anterior tibial and posterior tibial arteries with relative sparing of the peroneal artery and no difference in the plantar vessels. CONCLUSION: It has been demonstrated that the Bollinger score can be extended to include the distal vessels. This amended scoring system can be used to compare the burden of distal disease in patients with PAD. How the score relates to clinical presentation and outcomes needs further investigation.

RESUMO

We report the 3-year follow-up result of Wingspan intracranial stenting for symptomatic severe in-stent stenosis after stent-assisted coiling (SAC) for a ruptured left distal internal carotid artery (ICA) aneurysm. A middle-aged male patient visited our hospital for in-stent stenosis of a stent that was placed to treat a ruptured ICA aneurysm. Routine follow-up cerebral angiography, 1 year after SAC, showed in-stent stenosis around the distal markers of the inserted stent at the left M1 proximal segment. Six months later, he developed right dysesthesia. We performed intracranial stenting with Wingspan stent for the in-stent stenosis. Follow-up digital subtraction angiography performed 1 year after the Wingspan stenting showed good patency of the ICA and middle cerebral artery flow without evidence of restenosis. At 3-year follow-up, magnetic resonance angiography showed sufficient middle cerebral artery flow although the stenting segment could not be visualized clearly. Wingspan stenting might be a feasible option in patients with iatrogenic intracranial stenosis resulting from in-stent stenosis who experience the progression of intracranial stenosis with manifestation of neurological symptoms despite dual anti-platelet therapy.

RESUMO

ABSTRACT: Some evidences suggest the involvement of the central nervous system in patients infected with SARS-CoV-2. We aim to analyze possible associations between coronavirus disease 2019 (COVID-19) pandemic and spontaneous subarachnoid hemorrhage (SAH), in a comprehensive neurological center.We conducted a retrospective case series of 4 patients infected by COVID-19, who developed spontaneous SAH. Clinical data were extracted from electronic medical records.Between March 24, 2020, and May 22, 2020, 4 cases (3 females; 1 male) of SAH were identified in patients infected with SARS-CoV-2, in a comprehensive neurological center in Brazil. The median age was 55.25 years (range 36 -71). COVID-19-related pneumonia was severe in 3 out of 4 cases, and all patients required critical care support during hospitalization. The patients developed Fisher grade III and IV SAH. Digital subtraction angiography (DSA) was performed in 3 of the 4 patients. However, in only 1 case, an aneurysm was identified. Inflammatory blood tests were elevated in all cases, with an average D-dimer of 2336 µg/L and mean C-reactive protein (CRP) of 3835 mg/dl The outcome was poor in the majority of the patients, with 1 death (25%); 2 (50%) remained severely neurologically affected (mRS:4); and 1 (25%) had slight disability (mRS:2).This study shows a series of 4 rare cases of SHA associated with COVID-19. The possible mechanisms underlying the involvement of SARSCoV-2 and SHA is yet to be fully understood. Therefore, SHA should be included in severe neurological manifestations in patients infected by this virus.

RESUMO

Sarcomas are a rare and fatal treatment complication following radiotherapy. Radiation-induced sarcomas (RISs) presenting as a gluteal abscess is a rarity, accounting for its varied presentation. We present a case of a middle-aged woman, post-chemo-radiation for carcinoma cervix 5 years ago, who presented with gluteal abscess. Achieving haemostasis post incision and drainage under anaesthesia was a challenge. On further evaluation, she was diagnosed with radiation-induced gluteal soft tissue sarcoma. Haemostasis was achieved after radiation following failed attempts of surgical and radiological interventions. She is currently planned for chemotherapy. Cancer survivors have an increased risk of developing a second malignancy following radiation treatment. RISs are highly aggressive, exhibit a varied clinical presentation and pose a challenge in early diagnosis; thus, have a poor outcome. RISs pose a diagnostic challenge; any dubious lesion in the previously irradiated field should raise suspicion and prompt aggressive management.

RESUMO

Visceral artery aneurysms (VAAs) are uncommon with an approximate incidence of 0.01%-0.2%. Gastroduodenal artery (GDA) aneurysm is a rare subtype of these uncommon visceral aneurysms that can be fatal if ruptured. We present a case of a 58-year-old Caucasian woman with a VAA and a large haematoma arising from an actively bleeding GDA. While patients with VAA may remain asymptomatic, with some of the aneurysms found incidentally during imaging, they may also present with abdominal pain, anaemia and possible multiorgan failure which may be fatal.

RESUMO

Post-traumatic direct carotid-cavernous fistulas may develop in patients with a closed head injury. The classical presentation is the Dandy's triad-chemosis, pulsatile proptosis and orbital bruit. Associated findings may include orbital pain, dilated episcleral corkscrew vessels, vision deficit and cranial nerve palsies. Cranial nerves-oculomotor (III), trochlear (IV), ophthalmic (V1), and maxillary (V2) divisions of trigeminal and the abducens (VI) lie in close association of the cavernous sinus. Abducens nerve (VI) lies close to the intracavernous internal carotid artery, within the substance of the sinus and is hence easily susceptible to vascular insult. The two sinuses connect across the midline and communicate freely with each other. Back pressure changes can present with the same sided or bilateral cranial nerve palsies. We report a rare association of a long-standing left-sided carotid-cavernous fistula with right eye abduction deficit and contralateral abducens palsy.
