Introduction: Rectus sheath hematoma is a rare entity. This report presents a clinical case of a rectus sheath hematoma in a patient with COVID-19 pneumonia and chronic myeloid leukemia, along with a review of the literature. Case Report: A 55-year-old male patient, hospitalized for COVID-19 pneumonia and chronic myeloid leukemia, presents with tachycardia and hypotension. Computed tomography shows a rectus sheath hematoma. Surgical management was performed to control bleeding and drainage of the hematoma. There were no postoperative complications or need for reoperation. Discussion: Hemorrhagic complications in patients with COVID-19 are seldomly reported. Bleeding is a possible complication in patients with chronic myeloid leukemia. It is important to take into account rectus sheath hematoma in patients with COVID-19 and/or chronic myeloid leukemia who present with abdominal pain, for early management by a multidisciplinary team. Conclusion: Active surveillance and a high index of suspicion are key to identifying potential bleeding complications in patients with COVID-19 and/or chronic myeloid leukemia.
ABSTRACT
Background: The aim of the study was assessment of post-operative outcomes of rectus sheath block and comparison ofoutcomes between rectus sheath block and sub cutaneous bupivacaine.Materials and Methods: This study enrolled 58 patients who were scheduled to undergo laparotomy. Group I – 30 patientsreceived rectus sheath block using bupivacaine by placing catheters in between the muscle and posterior rectus sheath.Group II – 28 patients received bupivacaine infiltration by placing catheters in the subcutaneous plane. Visual analog scale(VAS) score, peak expiratory flow rate (PEFR), rescue analgesia, and complications were noted and follow-up of thesepatients was done.Results: Both the groups were comparable, hemoglobin concentration and anesthesiologists grades (statisticallyinsignificant). The majority of the patients from rectus sheath block group had VAS scores <5 comparing to subcutaneousinfiltration group which was statistically very significant (P ≤ 0.001). There was a statistically significant improvement ofpost-operative PEFR values in Group I as compared to Group II (P < 0.001). In Group I, 20 patients showed VAS scoreof 1 (no pain) at rest as compared only four patients in Group II. Rate of infection was more common in group receivingsubcutaneous infiltration.Conclusion: The patients from rectus sheath block group showed a statistically significant decrease in post-operative painin terms of VAS scores compared to that of subcutaneous bupivacaine infiltration group. There was statistically significantdecreased use of opioids as rescue analgesic in the rectus sheath group compared to that of the subcutaneous bupivacaineinfiltration group.
ABSTRACT
Objectives: Rectus sheath hematoma (RSH) can result from bleeding into the rectus abdominis muscle or a direct muscular tear; nontraumatic spontaneous RSH is a rare condition. Here, we report a case of spontaneous RSH associated with warfarin administration for the treatment of chronic thromboembolic pulmonary hypertension (CTEPH).Patient: An 87-year-old woman was referred to our hospital because of abdominal pain, nausea, and vomiting for 3 days. She was receiving warfarin for treating CTEPH. She had a bulging and hard lower abdomen with ecchymosis. Moreover, the bulging portion was highly tender, and a positive Carnett’s sign was also observed. She reported no history of abdominal trauma. Abdominal computed tomography (CT) scan revealed right RSH.Results: She was diagnosed with spontaneous RSH and admitted to our hospital. Warfarin was antagonized with an intravenous injection of vitamin K; hemostatic agents were intravenously administered. Gradually, her abdominal pain improved. She was finally discharged 12 days after the admission. Abdominal CT scan performed 17 days after the discharge revealed a reduction in the size of RSH.Conclusion: Despite not having a history of trauma, it is necessary to consider the possibility of RSH for patients receiving warfarin and complaining of abdominal pain.
ABSTRACT
La macrosomía es un factor de riesgo de traumatismos obstétricos y se asocia con morbimortalidad neonatal. El cefalohematoma y la fractura clavicular son los más frecuentes. Los traumatismos intrabdominales son poco frecuentes. El hematoma de la vaina de los rectos es una acumulación de sangre en la vaina del músculo recto mayor del abdomen. Se asocia con traumatismos, cirugías y tratamiento anticoagulante, en especial en los adultos y las personas de edad avanzada. En este artículo presentamos el caso de un recién nacido de sexo masculino con parto vaginal distócico. Durante el examen físico se observó un hematoma periumbilical de 1 x 1 cm y un cefalohematoma parietal de 1 x 1 cm. En la ecografía abdominal y la tomografía computada del abdomen se observó un hematoma de la vaina del recto derecho de 7 x 4 x 2 cm.
Macrosomia is a risk factor for birth injuries and is associated with neonatal morbidity and mortality. Cephalohematoma and clavicular fracture are the most frequent birth injuries. Intraabdominal injuries are uncommon birth injuries. Rectus sheath hematoma (RSH) is an accumulation of blood in the sheath of rectus abdominis muscle. It is associated with trauma, operations and anticoagulant therapy, especially in adults and elders. We present a macrosomic male neonate with difficult vaginal delivery, who had in the physical examination periumblical ecchymose of 1x1 cm and a parietal cephalohametoma of 1x1 cm. The abdominal ultrasonogram and the computed tomography scan of the abdomen showed a 7x4x2 cm right rectus sheath hematoma.

Background: Casual internet surfing at times proves extremely rewarding with astonishing results. Chance finding of an unknown old PhD thesis prompted documentation of detailed description of retropubic spaces supplementary to the author’s recent publication (Ansari MM. Ann Int Med Den Res 2017; 3(5): SG25-31.). Methods: Prospective study in adult patients with inguinal hernia who underwent laparoscopic total extra-peritoneal preperitoneal (TEPP) hernioplasty through standard 3-midline-port technique at J. N. Medical College, Aligarh between 2010 and 2015. Results: Under excellent fibre-optic light and magnified view during preperitoneal laparoscopy, multiple potential retropubic spaces were observed in the retropubic region, ranging from 4 to 7 in number. A total of four fissile potential retropubic spaces were recognized in 46 cases of TEPP hernioplasty when the posterior rectus sheath was incomplete (single- or double-layered) and the preperitoneal fascia as well as transversalis fascia was single-layered; a total of five fissile potential retropubic spaces were observed when preperitoneal fascia was double-layered along with presence of a single- or double-layered incomplete posterior rectus sheath (N=8); a total of five fissile potential retropubic spaces was also observed when the preperitoneal fascia was single-layered and the posterior rectus sheath was found single-layered but complete extending upto the pubic bone (N=10); a total of six fissile potential retropubic spaces were observed when the preperitoneal fascia was double-layered along with the presence of a single-layered complete posterior rectus sheath (N=3); and a maximum of seven fissile potential retropubic spaces was recognized, given the presence of a double-layered complete posterior rectus sheath and a double-layered preperitoneal fascia at the same time (N=1). Conclusion: Instead of a single Retzius space, multiple loosely fissile potential interfascial spaces (4-7) were documented in retropubic region, necessitating re-evaluation of Retzius space anatomy, in order to help TEPP hernia surgeon to execute the procedure with ease, rapidity and safety.
ABSTRACT
Objective To observe anesthetic effects of ultrasound-guided rectus sheath block (RSB)in peritoneal dialysis catheter implantation in patients with end-stage renal disease. Methods A total of 75 uremic patients (38 males,37 females,aged 18-65 years,BMI 18.5-24 kg/m2,ASA physical status Ⅲ),scheduled for elective peritoneal dialysis catheterization,were randomly divided into three groups (n=25 each)using a random number table:group A:total intra-venous anesthesia;group B:rectus sheath block,0.5% ropivacaine 15 ml were injected into the lat-eral rectus sheath;group C:local infiltration anesthesia was performed with 1% lidocaine and 0.5% ropivacaine.The mean arterial pressure and heart rate at the point of entering the operating room (T0),10 min after anesthesia induction (T1),at the beginning of operation (T2),20 min after the beginning of operation(T3),and at the end of the operation(T4)were recorded.The VAS score and Ramsay score at 2,4,8,12,24 h after surgery were recorded.The duration of operation and the oc-currence of adverse reactions were recorded.Results In group A,compared with T0,MAP and HR at T1-T3decreased significantly (P<0.05).In group B,there were no difference among T0-T4.In group C,compared with T0,T1and T4,MAP and HR at T2,T3increased significantly(P<0.05). Compared with group C,the duration of operation time in group A and group B decreased significantly (P<0.05).Compared with group A and group C,the VAS score at each point of group B was lower (P<0.05).Compared with group B,the total number of remediation analgesia in group C increased significantly(P<0.05).There was no adverse reaction in all three groups.Conclusion Ultra-sound-guided rectus sheath block anesthesia is safe and effective in peritoneal dialysis catheter implanta-tion patients with end-stage renal disease,and is worthy of clinical promotion.
ABSTRACT
Objective To discuss the efficacy and safety of transversus abdominis plane block (TAPB) combined with rectus sheath block (RSB) for peritoneal dialysis catheter placement.Methods Thirty patients,ASA Ⅰ or Ⅱ,body mass index (BMI) 18-30 kg/m2,were scheduled for elective peritoneal dialysis catheter placement.They were randomly divided into three groups:local anesthesia group (group L),ultrasound-guided TAPB group (group T),ultrasound-guided TAPB combined with RSB group (group TR).Mean arterial blood pressure (MAP) and heart rate (HR) were recorded before (T0) and after (T1) anaesthesia,the beginning of operation (T2) and abdomen-closing (T3),6 h (T4),12 h (T5),24 h (T6) after surgery.The consumption of local anesthetic during the surgery,dezocine after the surgery,the score of visual analogue scale (VAS) during rest and movement at T2-T6 and the adverse reactions were recorded.Results At T3,MAP and HR in group L and group T were higher than those in group TR (P ＜ 0.05).At T4 and T5,MAP and HR in group L were higher than those in group T and group TR (P ＜ 0.05);the consumption of local anesthetic ropivacaine in group L and group T were more than that in group TR (P ＜ 0.05);the consumption of local anesthetic ropivacaine and dezocine in group L were more than that in group T (P ＜ 0.05).The VAS score was significantly lower in group T and group TR at T3,T4,T5 compared with that in group L (P ＜ 0.05).There were no adverse reactions.Conclusion Ultrasound-guided TAPB combined with RSB is safe and efficacious in patients undergoing peritoneal dialysis catheter placement.

ABSTRACT
Background: Laparoscopic surgery is associated with considerable postoperative pain, though it is less compared to open surgery. Post laparoscopic pain results from phrenic nerve irritation caused by residual gas, stretching of the intraabdominal cavity and peritoneal inflammation. The Modified Rectus Sheath Block (MRSB) is fairly easy and reliable procedure when performed using ultrasound guidance so it is compared with the intraperitoneal instillation method by using Inj. Bupivacaine for postoperative analgesia in diagnostic laparoscopy. Aim of the study was to assess and compare the effect of the USG guided modified rectus sheath block (MRSB) with the intraperitoneal instillation using Inj. Bupivacaine in diagnostic laparoscopy. Material and methods: It was prospective randomized study. The Patients were randomly allocated in two groups. Group A were given USG guided rectus sheath block and Group B was given Patel V, Mehta K, Patel K, Parmar H. Comparison of USG guided modified rectus sheath block with intraperitoneal instillation with Inj. Bupivacaine for postoperative pain relief in diagnostic laparoscopy. IAIM, 2016; 3(1): 85-89. Page 86 intraperitoneal 25 mg Bupivacaine. Patients with obesity, local anesthetic agent allergy and emergency surgeries were excluded. Pain was assessed 1, 6, 10 and 24 hours postoperatively by visual analogue pain score. Results: Postoperative pain was assessed by visual analogue pain score (VAS) at every hour for 24 hours postoperatively. The VAS was significantly lower in Group A at 6 and 10 hours postoperatively. After 6 hours the median pain score was 3 in group A while it was 7 in group B. After 8 hourrs the median pain score was 2 in group A compared with 5 in group B and after 10 hours the median score were 2 and 5 in group A, group B respectively (p<.001 and <0.004 respectively). No significant difference noted in pain score at 1 hour and 24 hour post laparoscopy among the two groups. Conclusion: USG guided modified rectus sheath block (MRSB) provides prolonged post operative analgesia than intraperitoneal instillation in diagnostic laparoscopy.
ABSTRACT
Objective To evaluate the efficacy and safety of bilateral transversus abdominis plane block (TAPB)combined with bilateral rectus sheath block (RSB)in abdominal surgery. Methods Ninety ASA Ⅰ or Ⅱ patients,35 males,55 females,aged 19-79 years,with body mass index 18-30 kg/m2 ,scheduled for elective laparoscopic cholecystectomy were randomly divided into three groups(n=30):ultrasound-guided bilateral TAPB combined with bilateral RSB group (group TR),ultrasound-guided bilateral TAPB group (group T),patient-controlled intravenous analgesia (PCIA)group (group P).In group TR,ultrasound-guided bilateral TAPB were performed with 20 ml of 0.22% ropivacaine mesylate injection in each side and ultrasound-guided bilateral RSB were per-formed with 10 ml of 0.22% ropivacaine mesylate injection in each side before surgery.In group T, ultrasound-guided bilateral TAPB were performed with 20 ml of 0.22% ropivacaine mesylate injection in each side and ultrasound-guided bilateral RSB were performed with 10 ml of NS in each side before surgery.In group P,ultrasound-guided bilateral TAPB were performed with 20 ml of NS in each side and ultrasound-guided bilateral RSB were performed with 10 ml of NS in each side before surgery, and PCIA was applied in group P.BP,HR,SpO2 were observed when patients were sent into the op-erating room, 2 minutes before trocar puncture, and 2 minutes after trocar puncture, the consumption of propofol and remifentanil used during the surgery were recorded.The score of visual analogue scale (VAS)during rest and movement were recorded at 2,6,12,24 h after surgery.The patient analgesia satisfaction and the adverse reactions were recorded.Results Compared with group T and group P,group TR had less change of BP before and after trocar puncture(P <0.05).The VAS score was significantly lower in group TR after operation(P <0.05).There were no statistical significant differences of VAS score at 24 h after operation among the three groups.The patient anal-gesia satisfaction was significantly better in group TR than other two groups (P < 0.05 ). Conclusion Ultrasound-guided bilateral transversus abdominis plane block combined with bilateral rectus sheath block is of safety and much efficacy of postoperative analgesia in patients undergoing laparoscopic cholecystectomy.
ABSTRACT
Patients presenting for emergency abdominal procedures often have medical issues that cause both general anaesthesia and central neuraxial blockade to pose significant risks. Regional anaesthetic techniques are often used adjunctively for abdominal procedures under general anaesthesia, but there is limited published data on procedures done under peripheral nerve or plexus blocks. We herein report the case of a patient with recent pulmonary embolism and supraventricular tachycardia who required colostomy refashioning. Ultrasonography-guided regional anaesthesia was administered using a combination of ilioinguinal-iliohypogastric, rectus sheath and transversus abdominis plane blocks. This was supplemented with propofol and dexmedetomidine sedation as well as intermittent fentanyl and ketamine boluses to cover for visceral stimulation. We discuss the anatomical rationale for the choice of blocks and compare the anaesthetic conduct with similar cases that were previously reported.

Rectus sheath hematoma is a well documented clinical entity, though uncommon and often clinically misdiagnosed cause of acute abdomen. The non-specific nature of presentation combined with a lower incidence of the disorder leads to difficulty in diagnosing. Our patient presented with rectus sheath hematoma, following caesarean section on 9th post-operative day. She presented with wound discharge and lower abdominal pain. The case report is presented to increase the awareness in considering this entity in the differential diagnosis and management of acute lower abdominal pain. Rectus sheath hematoma’s early diagnosis and appropriate treatment may help to prevent complications.

Rectus sheath hematoma (RSH) is an uncommon condition caused by hemorrhage into the rectus sheath. RSH is characterized by abdominal pain and an abdominal mass. This condition is associated with old age, childbirth, abdominal surgery, severe coughing, severe sneezing, anticoagulation therapy, and/or coagulation disorders. We report herein a case of RSH and pelvic cavity hematoma that was induced by dalteparin injection in a 77-year-old woman with pulmonary embolism and deep vein thrombosis, and who was successfully treated by conservative management.

Rectus sheath hematoma is a rare complication of anticoagulant therapy. We have described the case of a 78-year-old woman with unstable angina who developed a life-threatening rectus sheath hematoma during treatment with antiplatelet drugs and enoxaparin. The patient had underlying diseases of hypertension and triple vessels disease status post coronary artery bypass graft. She was admitted initially with an asthmatic attack. Three days later, she developed unstable angina and thus received aspirin, clopidogrel, and enoxaparin. After the fifth dose of enoxaparin, she developed progressive suprapubic pain with a newly palpable mass, anemia, hypotension, and oliguria. Abdominal computed tomography revealed a rectus sheath hematoma sized 15 cm., (about 2,000 mL by volume). Her coagulogram was normal. Despite rapid fluid resuscitation, packed red cell transfusion (1,300 mL), platelet transfusion, and protamine sulfate injection, the patient’s hemodynamic status remained unstable. Finally recombinant activated factor VII (rFVIIa) injection improved her hemodynamic status and stabilized her hemoglobin level without a thrombotic complication. This case report provides evidence of the benefit of rFVIIa use as a part of the treatment of refractory bleeding from enoxaparin.
ABSTRACT
We report a case in which feelings of abdominal distension and discomfort of the abdominal wall caused by malignant ascites were relieved by ultrasound-guided rectus sheath block. <b>Case report</b>: A 59-year-old man developed gastric cancer with malignant ascites and experienced feelings of abdominal distension, but no nausea, dyspnea, poor mobility, or limb edema. Symptom control was inadequate with diuretic therapy and abdominal paracentesis. Feelings of distension improved temporarily with ultrasound-guided rectus sheath block. A percutaneous catheter was then used to administer an infusion of 0.25% ropivacaine triweekly until his death 20 days later. <b>Conclusion</b>: Feelings of abdominal distension is one of various symptoms of severe ascites and is difficult to manage. Ultrasound-guided rectus sheath block can be used to relieve this symptom on a case-by-case basis.
ABSTRACT
BACKGROUND: Abdominal wall hematoma is due to trauma, coagulation disorders or anticoagulation therapy complications. METHODS: In this report we present a case of a 44-year-old female who suffered from blunt abdominal trauma and presented to the emergency department with sharp abdominal pain and ecchymosis. FAST and abdominal computerized tomography (CT) revealed an abdominal wall hematoma. Treatment with an ultrasound-guided percutaneous drainage was performed successfully. RESULTS: The patient remained under observation for six hours with serial ultrasound scans, and no signs of hematoma recurrence were present. She was discharged the same day with clinical improvement. CONCLUSION: Complete history investigation and clinical examination help to make a correct diagnosis of abdominal wall hematoma, select a prompt treatment, and reduce complications.
ABSTRACT
PURPOSE: Although the rectus abdominis and its sheath are well known structures, their development in the human fetus is poorly understood. MATERIALS AND METHODS: We examined rectus abdominis and sheath development in semiserial horizontal sections of 18 fetuses at 5-9 weeks of gestation. RESULTS: Rectus muscle differentiation was found to commence above the umbilicus at 6 weeks and extend inferiorly. Until closure of the anterior chest wall via fusion of the bilateral sternal anlagen (at 7 weeks), the anterior rectal sheath originated from the external oblique and developed towards the medial margin of the rectus abdominis at all levels, including the supracostal part. After formation of the anterior sheath, fascial laminae from the internal oblique and transversus abdominis contributed to formation of the posterior rectus sheath. However, the posterior sheath was absent along the supracostal part of the rectus abdominis, as the transversus muscle fibers reached the sternum or the midline area. Therefore, it appeared that resolution of the physiological umbilical hernia (8-9 weeks) as well as chest wall closure was not required for development of the rectus abdominis and its sheath. Conversely, in the inferior part of the two largest fetal specimens, after resolution of the hernia, the posterior sheath underwent secondary disappearance, possibly due to changes in mechanical stress. CONCLUSION: Upward extension of the rectus abdominis suddenly stopped at the margin of the inferiorly developing pectoralis major without facing the external intercostalis. The rectus thoracis, if present, might correspond to the pectoralis.

The pattern of formation of the human rectus sheath exhibits variations, it is not clear if these variations are population specific. This study aimed at describing the pattern of formation of the rectus sheath in a select Kenyan population. Formation of the rectus sheath was analyzed in eighty subjects (47 male, 33 female) during autopsies and cadaveric dissection. The anterior wall of the rectus sheath in all cases was aponeurotic and firmly attached to rectus abdominis muscle. The posterior wall of the rectus sheath was aponeurotic in 71 (88.5 percent) cases, the rest were musculoaponeurotic and only seen in males. In all cases the aponeurosis of internal oblique abdominis split into two lamina; a deep lamina that fused with the aponeurosis of transverses abdominis at the lateral border of rectus abdominis and a superficial lamina that fused with aponeurosis of external oblique abdominis mid-way between the medial and lateral borders of rectus abdominis muscle. The pattern of formation of the rectus sheath among Kenyans shows some variations which have not been reported by previous workers. Knowledge of these variations is important in surgery as this sheath is always incised when making most aabdominal incisions.
El patrón de formación de la vaina del músculo recto abdominal humano muestra variaciones, no está claro si estas variaciones son población-específicas. Este estudio tiene como objetivo describir el patrón de formación de la vaina del músculo recto del abdomen en una población seleccionada de Kenia. La formación de la vaina del músculo recto del abdomen se analizó en 80 sujetos (47 hombres, 33 mujeres) durante autopsias y disección de cadáveres. La pared anterior de la vaina del músculo recto en todos los casos era aponeurótica y firmemente unida al músculo recto abdominal. La pared posterior de la vaina del músculo recto era aponeurótica en 71 (88,5 por ciento) casos, las paredes restantes eran musculoaponeuróticas y sólo se observaron en varones. En todos los casos, la aponeurosis del músculo oblicuo interno del abdomen se dividió en dos láminas, una lámina profunda que se fusionaba con la aponeurosis del músculo transverso del abdomen en el borde lateral del músculo recto del abdomen y una lámina superficial que se fusionaba con la aponeurosis del músculo oblicuo externo del abdomen a mitad del recorrido entre los bordes medial y lateral del músculo recto del abdomen. El patrón de formación de la vaina del músculo recto del abdomen, entre los kenianos muestra algunas variaciones que no han sido reportadas en trabajos anteriores. El conocimiento de estas variaciones es importante en cirugía ya que esta vaina es seccionada en abordajes abdominales.

Rectus sheath hematoma is an uncommon cause of acute abdomen, caused by a tear in deep epigastric vessels or its branches. It occurs spontaneously, after trauma or surgery. Rectus abdominus myonecrosis is a life threatening complication of rectus sheath hematoma. We report a case with fatal rectus sheath hematoma complicated by rectus abdominus myonecrosis caused by ischial fracture in a chronic active rheumatoid arthritis patient.
